Central venous catheter exchange by guidewire for treatment of catheter-related bacteraemia in patients undergoing BMT or intensive chemotherapy. (1/1115)

Current guidelines for the treatment of catheter-related bacteraemia (CRB) advise against central venous catheter (CVC) exchange because of the potential risk of prolonging infection. However, there are no consistent data proving this recommendation. We evaluated prospectively the usefulness of CVC exchange by guidewire for the treatment of CRB in patients undergoing BMT or intensive chemotherapy. CVC exchange was considered when fever and positive blood cultures persisted after 2 days of adequate antimicrobial therapy and no potential source of bacteraemia other than CVC could be identified. The guidewire exchange was preceded and followed by a slow infusion of adequate antimicrobial therapy. Bacteraemia was confirmed as catheter-related by demonstrating concordance between isolates from the tip and blood cultures by pulsed-field electrophoresis of genomic DNA. This procedure was performed in 19 episodes of bacteraemia during a 1-year period. Fourteen episodes (74%) were catheter-related and 71% of these were due to coagulase-negative staphylococci. Guidewire replacement was accomplished uneventfully 4 days after development of sepsis (range 3-6). In all cases, clinical signs of sepsis disappeared in less than 24 h after replacement. Definitive catheter withdrawal was carried out a median of 16 days (range 3-42) after guidewire exchange; in all cases, the tip culture was negative. We conclude that CVC replacement by guidewire under adequate antimicrobial therapy may be a reasonable option for the treatment of CRB when antimicrobial therapy alone has been unsuccessful.  (+info)

Right atrial bypass grafting for central venous obstruction associated with dialysis access: another treatment option. (2/1115)

PURPOSE: Central venous obstruction is a common problem in patients with chronic renal failure who undergo maintenance hemodialysis. We studied the use of right atrial bypass grafting in nine cases of central venous obstruction associated with upper extremity venous hypertension. To better understand the options for managing this condition, we discuss the roles of surgery and percutaneous transluminal angioplasty with stent placement. METHODS: All patients had previously undergone placement of bilateral temporary subclavian vein dialysis catheters. Severe arm swelling, graft thrombosis, or graft malfunction developed because of central venous stenosis or obstruction in the absence of alternative access sites. A large-diameter (10 to 16 mm) externally reinforced polytetrafluoroethylene (GoreTex) graft was used to bypass the obstructed vein and was anastomosed to the right atrial appendage. This technique was used to bypass six lesions in the subclavian vein, two lesions at the innominate vein/superior vena caval junction, and one lesion in the distal axillary vein. RESULTS: All patients except one had significant resolution of symptoms without operative mortality. Bypass grafts remained patent, allowing the arteriovenous grafts to provide functional access for 1.5 to 52 months (mean, 15.4 months) after surgery. CONCLUSION: Because no mortality directly resulted from the procedure and the morbidity rate was acceptable, this bypass grafting technique was adequate in maintaining the dialysis access needed by these patients. Because of the magnitude of the procedure, we recommend it only for the occasional patient in whom all other access sites are exhausted and in whom percutaneous dilation and/or stenting has failed.  (+info)

Evidence for nasal carriage of methicillin-resistant staphylococci colonizing intravascular devices. (3/1115)

Nasal surveillance cultures were performed for 54 patients exhibiting >/=10(3) CFU of methicillin-resistant coagulase-negative staphylococci per ml in central venous catheter (CVC) rinse cultures over a 6-month period. Forty-two of the nasal cultures yielded growth of methicillin-resistant coagulase-negative staphylococci, and 33 of the 42 cultures contained organisms that belonged to the same species as the CVC isolates. Of the 33 same-species isolates, 20 appeared to be identical strains by pulsed-field gel electrophoresis analysis. These data suggest that measures should be taken to reduce cross-contamination between the respiratory tract and intravascular devices. However, the potential interest in detecting methicillin-resistant coagulase-negative staphylococcus carriage in high-risk patients is hampered by the lack of sensitivity of nasal surveillance cultures.  (+info)

Central line sepsis in a child due to a previously unidentified mycobacterium. (4/1115)

A rapidly growing mycobacterium similar to strains in the present Mycobacterium fortuitum complex (M. fortuitum, M. peregrinum, and M. fortuitum third biovariant complex [sorbitol positive and sorbitol negative]) was isolated from a surgically placed central venous catheter tip and three cultures of blood from a 2-year-old child diagnosed with metastatic hepatoblastoma. The organism's unique phenotypic profile and ribotype patterns differed from those of the type and reference strains of the M. fortuitum complex and indicate that this organism may represent a new pathogenic taxon.  (+info)

Bloodstream infections can develop late (after day 100) and/or in the absence of neutropenia in children receiving allogeneic bone marrow transplantation. (5/1115)

We retrospectively evaluated the incidence and time from transplantation of bloodstream infections occurring in children receiving bone marrow transplant (BMT) at G Gaslini Children's Hospital between September 1984 and December 1997. During this period the incidence was 35% after allogeneic and 26% after autologous BMT (P=0.08). Among these episodes, 38% after allogeneic BMT and 90% after autologous BMT were detected in the presence of neutropenia within the first 30 days from reinfusion (P < 0.001). Incidence of catheter-related bloodstream infections was 40% after allogeneic and 8% after autologous BMT (P < 0.001). Bloodstream infections in the absence of neutropenia were 55% after allogeneic BMT vs 10% after autologous BMT (P < 0.001) and occurred later after reinfusion (mean 199 vs 41 days, P <0.001). Among the episodes occurring after allogeneic BMT and in the absence of neutropenia, 61% were related to the presence of a central venous catheter, 15% were related to the presence of GVHD, but 23% were not associated with any of major risk factors for infection. Finally, 38% of episodes following allogeneic BMT were detected after day 100 vs 1% after autologous BMT. We concluded that patients receiving allogeneic BMT experience a high incidence of bloodstream infections in the absence of neutropenia and that a significant proportion of these episodes is not clearly associated with well known risk factors such as GVHD or central venous catheters. Moreover, many episodes develop a long time after the transplantation procedure. Therefore, any febrile episode following allogeneic BMT even late and/or in the absence of neutropenia should be intensively managed.  (+info)

Short-term continuous infusion thrombolytic therapy for occluded central nervous venous dialysis catheters. (6/1115)

The necessity of maintaining a strict schedule of dialysis treatments in patients with chronic renal failure dictates that occluded access catheters be restored to full function in a timely and cost-effective manner. The records of 22 consecutive patients receiving outpatient treatment for occluded hemodialysis catheters at Osteopathic Medical Center of Texas were reviewed by the authors. Each patient had 100,000 units of urokinase in 50 ml normal saline instilled over 30 minutes through the occluded catheter. In most instances the dose was divided to allow 35 ml to the proximal port and 15 ml to the distal port. The maximum sustained blood flow rate on dialysis was recorded for each patient. The mean maximum sustained blood flow rate improved from 150 ml/min +/- 79 ml to 261 ml/min +/- 62 ml. Following infusion, improvement was obtained in 19 of 22 patients, with 14 catheters delivering blood flow greater than 250 ml/min. The total cost per treatment was $316. No adverse events were experienced. Thrombotic occlusion of extended use hemodialysis catheters can be rapidly and safely relieved in a cost-effective manner with little delay in scheduled dialysis treatments.  (+info)

Defibrillation-guided radiofrequency ablation of atrial fibrillation secondary to an atrial focus. (7/1115)

OBJECTIVES: Our aim was to evaluate a potential focal source of atrial fibrillation (AF) by unmasking spontaneous early reinitiation of AF after transvenous atrial defibrillation (TADF), and to describe a method of using repeated TADF to map and ablate the focus. BACKGROUND: Atrial fibrillation may develop secondary to a rapidly discharging atrial focus that the atria cannot follow synchronously, with suppression of the focus once AF establishes. Focus mapping and radiofrequency (RF) ablation may be curative but is limited if the patient is in AF or if the focus is quiescent. Early reinitiation of AF has been observed following defibrillation, which might have a focal mechanism. METHODS: We performed TADF in patients with drug-refractory lone AF using electrodes in the right atrium (RA) and the coronary sinus. When reproducible early reinitiation of AF within 2 min after TADF was observed that exhibited a potential focal mechanism, both mapping and RF ablation were performed to suppress AF reinitiation. Clinical and ambulatory ECG monitoring was used to assess AF recurrence. RESULTS: A total of 44 lone AF patients (40 men, 4 women; 32 persistent, 12 paroxysmal AF) with a mean age of 58+/-13 years underwent TADF. Sixteen patients had early reinitiation of AF after TADF, nine (20%; 5 paroxysmal) exhibited a pattern of focal reinitiation. Earliest atrial activation was mapped to the right superior (n = 4) and the left superior (n = 3) pulmonary vein, just inside the orifice, in the seven patients who underwent further study. At the onset of AF reinitiation, the site of earliest activation was 86+/-38 ms ahead of the RA reference electrogram. The atrial activities from this site were fragmented and exhibited progressive cycle-length shortening with decremental conduction to the rest of the atrium until AF reinitiated. Radiofrequency ablation at the earliest activation site resulted in suppression of AF reinitiation despite pace-inducibility. Improved clinical outcome was observed over 8+/-4 months' follow-up. CONCLUSIONS: Transvenous atrial defibrillation can help to unmask, map, and ablate a potential atrial focus in patients with paroxysmal and persistent AF. A consistent atrial focus is the cause of early reinitiation of AF in 20% of patients with lone AF, and these patients may benefit from this technique.  (+info)

Image-guided central venous catheters for apheresis. (8/1115)

Apheresis is an increasingly important procedure in the treatment of a variety of conditions, sometimes performed via peripheral access because of concern over major complications associated with central venous catheter (CVC) placement. This study sought to determine the safety and success for ultrasound and fluoroscopically guided, non-tunneled dual lumen CVCs placed for apheresis. Prospective data collection was made of 200 attempted CVC placements in the radiology department utilizing real time sonographic guidance. The complications relating to placement were noted in all and the number of passes required for venepuncture and whether a single wall puncture was achieved was recorded in 185 cases. Duration of catheterization and reason for line removal were recorded in all. Our study group included 71 donors providing peripheral blood stem cells for allogeneic transplant. CVCs were successfully placed in all patients, 191 lines in the internal jugular and seven in the femoral vein. 86.5% required only a single pass and 80.5% with only anterior wall puncture. Inadvertent but clinically insignificant arterial puncture occurred in six (3%) cases. In no case did this prevent line placement. There were no other procedure-related complications. 173 (87.4%) catheters were removed the same day. No catheters were removed prematurely. There was one case of prolonged venous bleeding. Our study demonstrates the safety of central venous catheters for apheresis provided that duration of catheterization is short and real-time sonographic guidance is used for the puncture, and guide wire and catheter placement are confirmed fluoroscopically.  (+info)

TY - JOUR. T1 - Advances in the Diagnosis and Management of Central Venous Access Device Infections in Children. AU - Bowan, Asha. AU - Carapetis, Jonathan. PY - 2011. Y1 - 2011. N2 - Infection is a well-known complication of central venous access device (CVAD) use, with an incidence of 3-6 bloodstream infections per 1,000 catheter days in children. Prevention of CVAD infections has improved with new strategies including the use of chlorhexidine antisepsis, bundles, maximal sterile barriers for insertion, prophylactic locks, antibiotic impregnated catheters and tunnelling of long-term devices. Despite these strategies, catheter-related bloodstream infections (CRBSIs) continue to be an important health problem. New approaches to diagnosis include differential time to positivity and quantification of blood cultures and molecular diagnostics. The management of CRBSIs includes techniques for line salvage including ethanol, antibiotic, hydrochloric acid, taurolidine and urokinase locks. When these ...

Bacterial colonisation of central venous access devices (CVADs) is a major cause of morbidity and potential cause of mortality in children receiving cancer chemotherapy. Catheter related bacterial infections can occur in the form of exit site infection (erythema, tenderness or swelling with positive skin swab), tunnel infection (erythematous tracking along the catheter path), colonisation of the line (positive blood culture from CVAD or fever/rigor with line flush, peripheral venous cultures sterile) or true catheter related bacteraemia (bacterial isolation from central and peripheral blood cultures)(Bishop). Device removal is frequently advised to manage the infection. However, it can result in significant morbidity, which includes the need for general anaesthesia during removal and reinsertion of a new line, and delay in chemotherapy. Particular problems arise with recurrent infections following CVAD colonisation. These concerns prompted early researchers to try alternative measures using ...

Central venous catheters, often needed by cancer patients, can be the source of Nocardia bacteremia. We evaluated the clinical characteristics and outcomes of 17 cancer patients with Nocardia bacteremia. For 10 patients, the bacteremia was associated with the catheter; for the other 7, it was a disseminated infection. N. nova complex was the leading cause of bacteremia. Nocardia promoted heavy biofilm formation on the surface of central venous catheter segments tested in an in vitro biofilm model. Trimethoprim- and minocycline-based lock solutions had potent in vitro activity against biofilm growth. Patients with Nocardia central venous catheter-associated bloodstream infections responded well to catheter removal and antimicrobial drug therapy, whereas those with disseminated bacteremia had poor prognoses ...

OBJECTIVE: To compare venous access device indications and complications, highlighting the use of midline catheters as a potentially cost-effective and safe approach for venous access in the ED.. DISCUSSION: Midline catheters (MC) offer a comparable rate of device-related bloodstream infection to standard peripheral intravenous catheters (PIV), but with a significantly lower rate than peripherally inserted central catheters (PICC) and central venous catheters (CVC) (PIV 0.2/1000, MC 0.5/1000, PICC 2.1-2.3/1000, CVC 2.4-2.7/1000 catheter days). The average dwell time of a MC is reported as 7.69-16.4 days, which far exceeds PIVs (2.9-4.1 days) and is comparable to PICCs (7.3-16.6 days). Cost of insertion of a MC has been cited as comparable to three PIVs, and their use has been associated with significant cost savings when placed to avoid prolonged central venous access with CVCs or in patients with difficult-to-access peripheral veins. Placement of a MC includes modified Seldinger and ...

As per our a priori definition of feasibility, a large efficacy trial of tunneled, cuffed CVAD securement and dressing in pediatrics, using these intervention arms, is feasible. Study processes were successful, with targets for eligibility, recruitment, retention, attrition, protocol adherence and missing data achieved. The proportion of failure (6%) and complication (6%) have provided point estimates for future interventional studies; and for a 5% absolute reduction in CVAD failure or complication is to be reached in future efficacy studies (p = 0.05; 80% ...
Central venous catheters (CVCs) are thin, flexible tubes that are inserted through the skin into a large vein, often in the arm or chest. The tube can then be used to give fluids, medicine and nutrition to chronically and critically ill patients. However, CVCs pose a significant risk of infection by providing a way for…
Controversy surrounds the role of central venous catheters (CVCs) impregnated with antimicrobial agents in the prevention of catheter-related bloodstream infection (CRBSI). We reviewed the current literature to evaluate the efficacy of antimicrobial-impregnated CVCs for preventing CRBSI. Eleven randomized studies published in article form were identified that included a control group that received nonimpregnated CVCs. We evaluated study methodologies, inclusion of key patient characteristics, use of clinically relevant end points, and molecular-relatedness studies. Review of these 11 trials revealed several methodological flaws, including inconsistent definitions of CRBSI, failure to account for confounding variables, suboptimal statistical and epidemiological methods, and rare use of clinically relevant end points. This review also failed to demonstrate any significant clinical benefit associated with the use of antimicrobial-impregnated CVCs for the purpose of reducing CRBSI or improving ...
Where to place a central venous catheter is a decision driven mainly by individual experience and preference. The limited evidence available has not established any site as superior; the subclavian position has been reported as being less infection-prone, but more likely to cause pneumothorax, compared to other sites. A large French randomized trial adds significantly to the evidence base.. Authors of the 3SITES study randomized more than 3,000 patients in France requiring central venous catheterization to have their line placed in either the internal jugular, subclavian, or femoral position.. To increase power (i.e., to reduce the number of enrolled patients needed to confidently find an effect), the primary outcome was a composite of either a catheter related bloodstream infection, or a deep venous thrombosis at the site.. Ultrasound was only used two-thirds of the time in internal jugular line placements (vs. 16% in subclavian line placements).. Chlorhexidine antiseptic was used less than ...

Millions of intravascular catheters are purchased each year by hospitals and clinics, placing many patients at risk for serious catheter-related infections. This chapter summarizes the rapidly expanding body of literature concerning prevention of intravascular catheter-related infections in the hope of reducing the risk posed to present and future patients. Prophylaxis with vancomycin or teicoplanin during central venous catheter insertion does not reduce the incidence of catheter-related bloodstream infection. The addition of prophylactic vancomycin to flush solutions or total parenteral nutrition solutions significantly reduces the incidence of catheter-related bloodstream infection; however, use of systemic antimicrobial agents to prevent intravascular catheter-related infections is not recommended. Administering very low doses of warfarin reduces thrombosis due to long-term central venous catheters. Use of prophylactic heparin by bolus infusion or when it is added to intravenous solutions does not
Central venous catheters are often inserted for a variety of clinical indications. In 1953, Sven-Ivar Seldinger introduced the technique of placing a central venous catheter by threading ...
Care of a central venous catheter depends on the type of catheter and whether a port is present. It is extremely important to follow the care instructions provided after a central venous catheter is in place to avoid infection or blockage. To prevent blockage, central venous catheters must be flushed routinely with a sterile solution, depending on the type of catheter. The catheter must be clamped securely and the tip covered tightly. Catheters that are connected to a port under the skin need less routine care, although most require flushing to prevent blockage.. A central venous catheter that has an exterior exit point must be kept dry during showers, and it must be protected from crimping or twisting caused by clothing or other articles rubbing against it. Occasionally, a central venous catheter may move out of its original location and require repositioning by the doctor. If it cannot be repositioned, the central venous catheter may have to be removed or reinserted. Any signs that the central ...
Central venous catheters (CVC) or lines (CVL) refer to a wide range of central venous access devices but can broadly be divided into four categories. They may be inserted by medical, surgical, anesthetic/ITU, or radiology specialists. Classifica...

Background: Peripherally inserted central catheters (PICCs) related complications are common in catheterization patients. Many patients with PICC catheterization have diabetes mellitus. The data of incidence and risk factors in diabetic patients are scarce. Methods: A retrospective, multicenter study was performed on diabetic patients with PICC insertion from May 2017 to June 2018. A mobile App was used to collect patients and insertion information. We used univariable and multivariable analysis to examine the risk factors of PICC-related complications. Results: A total of 103 diabetic patients were included with 13 (12.6%) patients developed complications. In univariable analysis, marriage (|i|P|/i|=0.002), prior surgery (|i|P|/i||0.001) were associated with complications. Following logistic regression analysis, marriage (OR 0.13, 95 CI% 0.03-0.58, |i|P|/i|=0.007) and prior surgery (OR 2.30, 95% CI 2.33-42.68, |i|P|/i|=0.002) remained to be independent risk factors of complications. Conclusion: For

Central venous catheters (CVC) are vital for patients receiving chemotherapy not compatible with peripheral infusion. Thousands of centrally and peripherally inserted central venous catheters are inserted into patients with cancer each year. All types of intravascular catheters are associated with complications. These complications may be divided into infectious, thrombotic, mechanical and occlusive events. All of these events have the potential to harm patients and cause additional expense for the health-care system. Furthermore, the above-mentioned complications are largely avoidable through proper patient selection, insertion technique, hygiene precautions and catheter maintenance.. Catheter-related infections and deep venous thrombosis are the two most common and feared CVC related complications. Infection in a catheter can cause lifethreatening bacteraemia, and thrombosis can lead to pulmonary embolisation, post-thrombotic syndrome and stenosis of the vessel affected. Many studies ...
In this video Dr. Ola Borgquist makes the case for ultrasound-guided, right-sided subclavian central venous lines and introduces the microconvex transducer as a great tool in your practice. As Dr. Borgquist explains the learning curve is not as steep as with other procedures and he expects you will soon be convinced that this is a great technique for central venous catheterisation! Dr Ola Borgquist works as an anesthesiologist/critical care physician at the Department of Anesthesia & Critical Care of Skåne University Hospital in Lund, Sweden. His PhD thesis, Negative Pressure Wound Therapy - therapy settings and biological effects in peripheral wounds, was published in 2013. Currently, his research encompasses both cardiac arrest (the TTM2-trial) and central venous catheterisation (evaluation of complications). Dr. Borgquist is an avid fan of ultrasound-guided procedures (venous lines, regional anesthesia) and tries to help colleagues learn through instructional videos (www.interanest.org).
Central venous access is one of the most common surgery procedures worldwide, especially in pediatric surgery. Local and regional complications as the result of venous catheter permanence time are frequently described as: thrombosis, infection, edema and local cellulite, movement and loss of the catheter. Other severe complications such as endocardiac and hemorrhagic lesions are also described and considered the cause of catheter early removal. In the literature few studies have addressed vascular and perivascular lesions and complications as the result of central venous access to peripheral veins, given the difficulty of setting up venous catheterization experimental models to study blood vessels and perivascular tissue alterations after catheterization. In the present venous catheterization experimental model, rabbits were divided into two groups based on the time that the venous catheters were maintained in their veins. Group a composed of 7 New Zealand male rabbits was submitted to a 15-day

An observational study of using octenidine on the skin of patients in 17 intensive care units in Berlin in 2014 showed decreasing nosocomial infection rates.[6]. In a survey of German neonatal intensive-care units octenidine without phenoxyethanol and octenidine were the most common skin antiseptics used for intensive-care procedures. Skin complications included blistering, necrosis and scarring, which has not been previously reported in this population.[3]. In a 2016 study of pediatric cancer patients with long-term central venous access devices using octenidine/isopropanol for the disinfection of catheter hubs and 3-way stopcocks as part of a bundled intervention, the risk of bloodstream infections decreased.[7]. ...
Evaluating the source of fever with a through history, physical and laboratory testing is imperative in this population. Catheter-related bloodstream infection (CRBSI) should always be suspected if there is no obvious alternative source. Blood cultures are necessary to determine potential pathogens. If a central catheter is present then cultures should be taken from each lumen. Taking two blood culture specimens increases the likelihood of discovering true bacteremia. In one study, 32 to 43 percent of double lumen catheter cultures that resulted positive were positive from only one of multiple lumens.. Controversy exists regarding the value of peripheral cultures in addition to central catheter cultures if a central catheter is present. Although peripheral cultures may allow for more specific diagnosis of central catheter infection, the treatment of both entities is similar and in only rarely changes management. This pathway does not advocate for peripheral cultures.. Weight-based blood cultures ...
A patient admitted to an ICU is on central venous line for the last one week. He is on ceftazidime and amikacin. After 7 days of antibiotics he develops a spike of fever an his blood culture is positive for gram positive cocci in chains, which are catalase negative. Following this, vancomycin was started but the culture remained positive for the same organism even after 2 weeks of therapy. The most likely organism causing infection is ...
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered: Allergies Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

PURPOSE Antimicrobial lock therapy (ALT) seems a promising approach for treatment of central line associated bloodstream infections (CLABSI). The recent introduction of molecules such as daptomycin and tigecycline, alone or in combination with other molecules, improved chances of efficacy of ALT, due to their activity on the bacterial biofilm. Our aim was to review the literature concerning ALT for CLABSI, including data concerning novel molecules. METHODS We included case-control studies evaluating two or more molecules as ALT in central venous catheter infections extracted from the Medline database. Among 221 available articles in Pubmed, 54 were selected for their particular interest concerning ALT. RESULTS Incidence of CLABSI is high worldwide. Mechanisms of catheter infection include contamination by skin bacteria, hand contamination and hematogenous diffusion. Catheter-infection is associated with biofilm formation, which reduces the efficacy of ALT. The most promising situation for ALT to
OBJECTIVE: Continuous assessment of central venous oxygen saturation (S(cevox)O(2)) with the CeVOX device (Pulsion Medical Systems, Munich, Germany) was evaluated against central venous oxygen saturation (S(cv)O(2)) determined by co-oximetry. METHODS: In 20 cardiac surgical patients, a CeVOX fiberoptic probe was introduced into a standard central venous catheter placed in the right internal jugular vein and advanced 2-3 cm beyond the catheter tip. After in vivo calibration of the probe, S(cevox)O(2), S(cv)O(2), mixed venous oxygen saturation (S(mv)O(2)) haemoglobin (Hb), body temperature, heart rate, central venous and mean arterial pressure, and cardiac index were assessed simultaneously at 30 min intervals during surgery and at 60 min intervals during recovery in the intensive care unit. Agreement between S(cevox)O(2), and S(cv)O(2) was determined by Bland-Altman analysis. Simple regression analysis was used to assess the correlation of S(cevox)O(2), and S(cv)O(2) to Hb, body temperature and ...
The use of US to reduce the number of complications related to vascular access for CVC placement has been evaluated in numerous previous studies in a variety of clinical settings. Recent Cochrane systematic reviews and meta-analyses summarize the current evidence for US guidance versus anatomic landmark techniques for CVC placement in the IJV [22], SV [23], and FV [23] with regard to complications of CVC placement. These meta-analyses included adult and pediatric patients treated in the intensive care unit or the operating room and compared conventional landmark techniques with techniques using static or real-time US or Doppler US. The primary outcome measure was the total rate of peri-interventional complications and adverse events.. For the IJV, 35 trials enrolling a total of 5108 patients were included in the meta-analysis [22]. The analysis demonstrated that the use of US for CVC placement in the IJV reduces the total rate of complications compared with conventional landmark techniques (US, ...
The ITNE will assess the patient and treatment characteristics and use an evidence based decision making algorithm for the selection of the most suitable VAD.. If the VAD needed is a PICC or a midline ITNE will place it following hospitals protocols. If needed, ITNE will also educate and support patients and next of keens in the maintenance of the device at home.. If other devices such as peripheral catheters, central venous catheters (jugular or subclavian) or venous subcutaneous reservoirs are the preferable VADs for patients and treatment conditions, ITNE will work together with health professionals in charge of patients to activate the usual procedures to place the according device. ...
Subjects will be admitted to the bone marrow transplant unit and put in isolation to reduce exposure to infectious agents.. Prior to transplantation, they will receive BUSULFAN via the central venous line, four times a day for four days, CYCLOPHOSPHAMIDE via the central venous line once a day for two days, and MELPHALAN via the central venous line for one day. Busulfan, cyclophosphamide, and melphalan are given to destroy the subjects cancer. As well, these drugs will destroy their immune system to help ensure the new stem cells take and grow after transplantation.. On the day of transplantation, umbilical cord blood from the donor will be transfused via venous line. These new cells will replace the subjects bone marrow.. After transplantation, the subjects will receive Cyclosporin A and either MMF or MTX. Isolation will be continued until adequate numbers of cells are present in the blood to fight infection. Subjects will be discharged from the hospital when medically ready. They will be ...
OBJECTIVE--Major thromboses can occur in the venous system in association with central venous catheters. This usually necessitates removal of the catheter. METHODS--The effectiveness of low dose recombinant tissue type plasminogen activator (rt-PA) in combination with heparin was assessed in patients with central venous catheter associated thrombosis. RESULTS--In five patients, all suffering from cancer, a 5-7 day continuous infusion resulted in complete lysis of the thrombus without complications in three. In the other two patients moderately severe haemorrhage was observed with only partial lysis, of the thrombus. CONCLUSIONS--The infusion of heparin and rt-PA is potentially effective in thrombosis related to use of central venous catheters, but the risk of haemorrhage is not inconsiderable.. ...

On day 67 of life, because of short bowel syndrome and intolerance of full enteral feeds of a semi-elemental formula, she was recommenced on parenteral nutrition (120 mL/kg/day) with some nasogastric feeds (60 mL/kg/day). Venous access was extremely difficult to obtain and after two different attempts a 24 French peripherally inserted central venous line (Neocath®, Vygon, Ecouen) was inserted through a right sided scalp vein. Blood was easily aspirated from the line at the time of insertion. As per our usual practice, the central venous catheter was slowly injected with 0.5 mL of Isovue 300 (Isovue® 300, Regional Health Care Products Group Medi-Consumabales Pty Ltd, Rosebery) and a radiograph was taken while injecting the dye (Figure 1) [1]. The tip was noted to be in a vessel at the level of the mandible and was deemed to be satisfactory for the infusion of parenteral nutrition. The Radiologists report stated the catheter tip location as the "internal jugular vein ...
In patients with chronic gastrointestinal tract failure, requiring access to the venous system, the subsequent catheter re-insertion are leading to large veins thrombosis impeding or preventing the insertion of another catheter and exposing patients to the risk of complications. Understanding the pathophysiology of catheter-related infections, enabled to use methods allowing to eradicate the source of infection without removal and replacement of central catheter with a new one. In our center, for many years we have been using an alternative method involving implementation of the alcohol-antibiotic lock in the treatment of infections. This method is based on the assumption that the destruction of biofilm with concentrated alcohol will enable antibiotic penetration and killing other microorganisms. Treatment with alcohol-antibiotic lock lasts from 8 to 10 days and involves filling the catheter with 96% alcohol followed by a solution of the antibiotic of high concentration.. The aim of the study ...
Disclosed are an apparatus and methods for initial, or replacement, central venous catherization using a flexible guidewire with markings thereon and a substantially translucent non-thrombogenic catheter. In operation, the guidewire is inserted along a catheter positioned in a vein. The marks on the guidewire are then used to establish, and maintain as constant, the position of the guidewire. Next, the catheter already in the vein is removed by sliding it over the guidewire, and a new catheter is slipped over the guidewire into position. Once the new catheter is positioned, the guidewire is removed.
Ok, so let me preface this with the fact that I walk around with a handheld ultrasound rather than a stethoscope, and that I examine ALL patients with a focused cardiopulmonary and abdominal exam. My bias towards bedside ultrasound is ridiculously huge. I think practicing without it, once the skill is acquired, is unethical. Having…
Another potential benefit to the use of DRGN-1 in the treatment of infections is its ability to prevent biofilm formation. Biofilms are essentially "slime cities" of bacteria which are relatively more resistant to antibiotics and therefore more difficult to treat. Biofilms are commonly found on infected prosthetic material and are one of the main reasons why infected prosthetics need to be removed. DRGN-1 has been shown to be able to prevent biofilm formation in the laboratory which might make it useful in treating infections where biofilm formation is a problem e.g. prosthetic joint infection, central venous catheter infection, urinary catheter infection ...
Central Venous Catheters (CVCs) are used to administer medications, intravenous fluids, and nutritional supplements. However, the insertion of a CVC creates a tiny opening in the skin, which raises the risk of infection. When these infections occur, they may spread to the bloodstream, which can lead to changes in blood pressure and fluid balance, organ dysfunction, and, in extreme cases, death. In fact, bacterial infections of the blood arising from central venous catheters are among the most common hospital-acquired infections in the intensive care unit.. ...
A central line placement is an invasive technical skill that is frequently performed in the hospital. Central lines may be placed in the neck, shoulder or groin area for lack of peripheral access, monitoring or introduction of multiple fluids.. Historically, resident physicians are trained by the "See one, Do one, Teach one" method. This means a resident typically watches one being performed by either an attending physician or a senior resident before doing one him or herself. Using this traditional method, trainees learn procedures vicariously through observation of their peers. If their peers have not been properly trained, mistakes are handed down from generation to generation of resident trainees. In addition, the use of ultrasound to place central lines could potentially minimize these risks.. If not done correctly, complications associated with central lines include pneumothorax (punctured lung), bleeding, hematoma, arterial puncture and infection. One study notes central venous catheter ...
Infections: The most common potential problem is a catheter infection. Although these catheters are placed in a sterile environment (the operating room), sometimes the skin harbors bacteria that can establish an infection. Other times, the bacteria are in your childs blood stream for other reasons and settle down on the inside of the catheter, starting a catheter infection. If a catheter infection occurs, it can usually be treated with antibiotics, however, sometimes the catheter will have to be removed.. Bleeding: At the time of placement of the catheter, the surgeon has two primary concerns, particularly when the catheter is placed with the needle method (the technical term is "percutaneous", or through the skin, i.e. without an actual incision). One is bleeding from the vein or the artery that is located next to the vein. This is not necessarily a major problem, unless your childs ability to stop bleeding is impaired, which may happen due to a low platelet count, for example. If the level ...

Central line complications are a major concern for hospitals and the healthcare sector, costing money and-most importantly-harm to patients. These complications are also highly preventable, as demonstrated by #simulation expert Dr. Yanick Beaulieu.. Central line (also "central venous") complications include placement failure of catheters and arterial punctures, as well as central line infections (CLIs). The reduction of CLIs, which is caused when a central venous catheter placed in a patients vein gets infected, is a particularly concern. For example, the Ontario Ministry of Health and Long Term Care (MOHLTC) now requires that all eligible hospitals submit data elements for CLIs in an effort to improve patient care and patient safety.. Dr. Beaulieu-a cardiologist at Hôpital Sacré-Coeur de Montréal and is an Assistant Professor at Université de Montréal-believes the best way to reduce central line complications is through ultrasound-guided simulation-based #education. A renowned expert in ...
Avoid Pressor Angst! Ordering that 3rd and 4th liter of fluid is an easy trap to fall into, but remember - 20-30cc/kg is usually no more than 2L of crystalloid. Excessive fluid administration often delays adjunctive intervention, can prolong the duration of hypotension, and may cause significant morbidity. We discuss "Pressor angst" as the mental hurdle that prevents a clinician from prescribing vasoactive therapy, often because it will define a patient as "critically ill" and increase the amount of resources they will require (central venous catheter placement, increased monitoring, and higher level of care at disposition). The patient likely needs these interventions, not an additional liter of crystalloid…. Dont delay vasoactives for central line placement. There is a growing body of evidence that peripheral vasoactive medication administration is safe3 It is appropriate to begin vasoactive medication peripherally early during resuscitation and then reassess the need for it after adequate ...
A tunnelled central venous catheter (also called external catheter or central line) is a long, flexible tube. One end of the catheter is placed in or near the right atrium of the heart and the other end is outside the skin of the chest. The tube tunnels under the skin of the chest, enters a large ve
A venous catheter is a tube inserted into a vein in the neck, chest, or leg near the groin, usually only for short-term hemodialysis. The tube splits in two after the tube exits the body. The two tubes have caps designed to connect to the line that carries blood to the dialyzer and the line that carries blood from the dialyzer back to the body. A person must close the clamps on each line when connecting and disconnecting the catheter from the tubes.. If kidney disease has progressed quickly, a patient may not have time for placement of an AV fistula or AV graft before starting hemodialysis treatments.. A nephrologist-a doctor who specializes in kidney problems-or an interventional radiologist-a doctor who uses medical imaging equipment to perform operations-performs the venous catheter placement procedure in a hospital or an outpatient center. The patient receives local anesthesia and sedation to stay calm and relaxed during the procedure.. Venous catheters are not ideal for long-term use. With ...
Chronic intestinal failure (IF) is caused by either surgically induced anatomical short bowel, severe motility, or absorption disorders. These patients require partial or total parenteral nutrition (PN and TPN, respectively) and are thereby critically dependent on maintaining venous access with a central venous catheter (CVC). Recurrent CVC-related thrombosis will ultimately lead to loss of central venous access with intestinal transplantation being the only treatment option left. Therefore, patients at risk for recurrent thrombosis and requiring (T)PN are often treated with long-term anticoagulants to prevent CVC-thrombosis, such as INR-adjusted vitamin K antagonists (VKAs) or low-molecular-weght heparins (LMWHs). A new generation of oral anticoagulants (NOACs), including dabigatran etexilate and rivaroxaban, has recently been approved for several indications. In contrast with VKAs, these drugs do not interact with vitamin K metabolism, have a more predictable pharmacokinetic profile, have less ...
Pediatric stem cell transplant and cancer patients often are discharged from the hospital with an external central venous line for medications that parents or other caregivers must clean and flush daily to avoid potentially life-threatening infections. If an outpatient develops a bloodstream infection associated with the central line, research from Dana-Farber/Boston Childrens Cancer and Blood Disorders Center finds, the median charges to treat it total $37,000 for a hospital stay of six days for young patients whose disease treatments have weakened their immune systems and infection-fighting abilities.. The results, published online by Pediatric Blood & Cancer, are part of the second phase of a collaborative effort among childrens hospitals to reduce central-line-associated bloodstream infections or CLABSIs. In the first phase, members of the Childrens Hospital Association Childhood Cancer and Blood Disorders Network reduced inpatient CLABSIs by 28 percent in less than three years, according ...

EARLY AND LATE COMPLICATIONS RELATED TO CENTRAL VENOUS CATHETERS IN HAEMATOLOGICAL MALIGNANCIES: A RETROSPECTIVE ANALYSIS OF 1102 PATIENTS
Central line insertion is an invasive procedure frequently performed in the intensive care unit (ICU). Patients in ICUs are at high risk of health care associated infections, including central line associated blood stream infections (CLAB), many of which are considered preventable. The Central Line Associated Bacteraemia in Intensive Care Units project (CLAB-ICU) is a NSW Statewide initiative that aims to improve patient outcomes, by reducing CLAB in ICUs. It advocates a standard sterile insertion practice. The project is overseen by the Intensive Care Co-ordination and MonitoringUnit (ICCMU) and the Clinical Excellence Commission (CEC), with the co-operation of the NSW Ministry of Healths Quality and Safety Branch. All level 5 and 6 ICUs are participating.. CLAB ICU is the first collaborative between the ICCMU and CEC providing an opportunity for clinicians to drive change at the coal face. ...

My senior supervisor Dr. Tomono Takahashi, whose speciality is Diabetology, also taught me about the examination and treatment of DM (diabetes mellitus). Not only did she teach me, but she organised visits for me in both Scintigraphy (of suprarenal gland) and an operation with the famous DaVinci robot in Urology (prostatectomy). It was fascinating to see them both. I also listened to a lecture about a nasal spray for allergic rhinitis in medical environment. My favourite procedure however was the adrenal vein sampling,in which I took part twice. I helped in putting the blood samples in the correct containers. I also learned how to insert a PICC (peripherally inserted central venous catheter) with ultrasound, which added a great skill to my medical carreer.

Results A total of 71 lines were placed in 53 infants , 33 weeks. 43% (53/131) infants , 33 weeks admitted had PICC line placed. The mean gestational age was 27.7±2.3 weeks and mean birth weight was 1030±332g. The indications for insertion was administration of Parenteral nutrition (86%), Inotropes (11%), and antibiotics (3%). The mean age at insertion was 7±6 days and the average duration of placement was 6±5 days. All the lines were inserted with maximum sterile barrier and 86% were accessed once per day under strict sterile protocol. 35% lines were correctly placed, 64% required manipulation and post manipulation catheter tip was confirmed in 64% cases. 58% of the lines completed treatment. Line occlusion was the most common complication (17%), which significantly reduced the duration of line placement by 3.3 days (p=0.02). The infection rate was 13 per 1000 catheter days.. ...

Substantial distress and delay to therapy can be caused to children undergoing haemodialysis when the central venous lines (CVLs), by which their treatment is delivered, are blocked by blood clots. Our research has shown that a new form of anti-coagulant, alteplase, is much more successful than the traditional agent, heparin, in preventing blockages. At the Royal Victoria Infirmary in Newcastle upon Tyne the annual probability of CVL replacement due to thrombosis was 0.7 prior to our work. Since alteplase has been used (2005-2012), no lines have had to be replaced because of thrombosis. This represents a remarkable reduction in the levels of distress to children and, by eliminating the delays associated with line replacement, effects financial savings for the NHS. As a result of our research alteplase is now used in 12 of the 14 paediatric kidney units in the UK and Ireland. The clinical trial which established the superiority of alteplase, required a novel form of optimal crossover ...
Throughout my internship I had so many amazing experiences. I was able to shadow a respiratory therapist and observe an intubation, participate in the PALS (pediatric advanced life support) course with the critical care fellows, follow attending physicians during rounds, learn how to place a central venous line (a special IV), learn how to place a breathing tube and how to properly ventilate a patient, watch a cardiac catheterization (a surgery during which a catheter is threaded through the patients vasculature all the way into his heart in order to diagnose or treat a condition), learn about cardiac arrhythmias and treat them using a defibrillator. I also learned about human anatomy, physiology, and medicine through watching and helping run simulations. Everyday was an adventure during which I knew that I would learn something new. ...

In many instances, the quantitative blood testing to determine the hormone can also be applied to assess and control some kinds of the cancer.. Cells, which are present within placenta, produce the hormone. This placenta is, in fact, a pouch, which nurtures the egg, just after this is fertilized completely and joins with the wall of uterine.. Human Chorionic Gonadotropin may be identified first in the blood specimen nearly eleven days following conception. The hormone level keeps on doubling after every three days. They get to the peak nearly 8 to 12 weeks after ones conception. The level of hormone then gets reduced and remains stable for remaining part of pregnancy.. Risks related to quantitative test. The dangers in this test are minimal. Slight bruising may occur at a point, where the doctor has inserted the needle.. In exceptional cases, there may be-. ...
I might be able to explain... I dont wear long line bras, but rather industrial strength ones - which are, by their very nature, long line. My natural bra size is 34KK, so as you can imagine I need a LOT of support. The reason why you might be feeling a little light headed has to do with weight distribution. The average bra - whether from Victorias Secret or Wal-Mart - has most of the load bearing in the shoulders. But a long line bra re-distributes the weight to be supported by the rib cage. Until you get used to that extra weight on your rib cage, pressing down on your lung area, you might not be taking as deep of breathes as youre used to. Another problem that can escalate this is a poor fitting bra. Most women in the US are used to such poorly fitting foundations that a properly fitted one feels wrong somehow. A properly fitted long line is tighter than you are used to - but its important! If you buy one thats bigger and looser you will actually have a HARDER time breathing because ...

We identified five new studies for this update (six prior studies were included in the original review), bringing the number of eligible studies to 11, with a total of 2392 participants. We noted differences in methods used by the included studies and variation in heparin concentrations (10 to 5000 IU/mL), time to follow-up (1 to 251.8 days), and the unit of analysis used (participant, catheter, line access). Combined results fromthese studies showed fewer occlusions with heparin than with NS (risk ratio (RR) 0.70, 95%confidence interval (CI) 0.51 to 0.95; P = 0.02; 1672 participants; 1025 catheters from 10 studies; I² = 14%) and provided very low-quality evidence. We carried out subgroup analysis by unit of analysis (testing for subgroup differences (P = 0.23; I² = 30.3%). When the unit of analysis was the participant, results show no clear differences in all occlusions between heparin and NS (RR 0.79, 95% CI 0.58 to 1.08; P = 0.15; 1672 participants; seven studies). Subgroup analysis using ...
In hospitalized hematology-oncology patients, culture of blood drawn through a central catheter or peripheral vein has excellent negative predictive value. Culture of blood drawn through an indwelling central venous catheter has a low positive predictive value, apparently less than seen with peripheral venipuncture. Thus, a positive result from a catheter needs clinical interpretation and may require confirmation. However, use of a catheter to obtain blood for culture may be acceptable for ruling out bloodstream infections. ...

After surgery, you will have tubes outside and inside of your body.. ​​​​​​​Drains from your incision. You will have an incision where the surgeon placed your new kidney. This area of the skin is usually closed with stitches (sutures) or staples and covered with a dressing.. You may have a thin plastic tube called a drain from the incision. This drains extra fluid from the surgery area and prevents it from collecting around the new kidney.. The sutures or staples are removed a few weeks after the surgery and it will take up to 6 weeks for the incision to heal.. Central venous catheter. A central venous catheter (CVC) is a tube in your neck that ​goes to the large vein above your heart. A CVC allows your healthcare team to give you fluids and medicines, draw blood for blood tests, and to check if you are getting enough fluids.. Foley catheter.

A tracheostomy is performed using an access device and a separate ventilation device. The access device is introduced through a surgical opening in the tracheal wall and has an anchor which is expanded in situ to hold the access device in place. The ventilation device is introduced through a passage in the access device and has an expandable cuff which is oriented above the access point through the tracheal wall. A concavity in the expandable cuff collects body secretions, and other materials from the oral and nasal cavities and/or gastro-intestinal reflux into the trachea, and the collected secretions are removed by aspiration through a lumen provided in the ventilation device. A one-way valve may be provided in the expandable cuff in order to permit exhalation through the larynx to assist in speech.

N2 - Background: Bedside placement of peripherally inserted central catheters (PICCs) may result in navigation to undesirable locations, such as the contralateral innominate or jugular vein, instead of the superior vena cava or right atrium. Although some guidance and tip location tools exist, they have inherent limitations because of reliance on physiological measures (eg, chest landmarks, electrocardiogram, etc), instead of anatomical assessment (ie, geometric changes in the vasculature). In this study, an accurate, anatomically based, non-X-ray guidance tool placed on a novel 0.035" conductance guidewire (CGW) is validated for PICC navigation and tip location. ...

Healthcare-associated infections (HAI) in preterm infants are a challenge to the care of these fragile patients. HAI-incidence rates range from 6 to 27 infections per 1000 patient-days. Most nosocomial infections are bloodstream infections and of these, the majority is associated with the use of central venous catheters. Many studies identified parenteral nutrition as an independent risk factor for HAI, catheter-associated bloodstream infection, and clinical sepsis. This fact and various published outbreaks due to contaminated parenteral nutrition preparations highlight the importance of appropriate standards in the preparation and handling of intravenous solutions and parenteral nutrition. Ready-to-use parenteral nutrition formulations may provide additional safety in this context. However, there is concern that such formulations may result in overfeeding and necrotizing enterocolitis. Given the risk for catheter-associated infection, handling with parenteral nutrition should be minimized and the
Central vein stenosis/occlusion is a common well-described sequel to the placement of hemodialysis catheters in the central venous system. The precise mechanisms by which central vein stenosis occurs are not well known. Current concepts in central vein stenosis pathophysiology focus on the response to vessel injury model, emphasizing the process of trauma. A case of left brachiocephalic vein stenosis due to the insertion and function of a temporary right subclavian hemodialysis catheter is presented. The purpose of the manuscript is to emphasize that, with the introduction of a temporary subclavian hemodialysis catheter via the right subclavian vein apart from causing concurrent stenosis/infarction of the right subclavian and right brachiocephalic vein, it is also possible to cause stenosis of the left brachiocephalic vein (close to its contribution to the superior vena cava) although the catheter tip is placed in the correct anatomical position in the superior vena cava ...
There is only 1 umbilical vein, and it remains open and viable for cannulation for up to 1 week after birth. The umbilical vein carries oxygenated blood from the placenta to the fetus. The UVC passes into the umbilical vein through the umbilicus and follows this path: junction of the right and left portal vein in the liver, the ductus venosus, crosses at the level of the right and left hepatic vein, and enters the inferior vena cava up to the junction of the inferior vena cava and right atrium. ...
Increasing number of people are being affected with Deep Vein Thrombosis (DVT) which will subsequently increase demand for LMWH. For instance, according to National Center on Birth Defects and Developmental Disabilities, Centers for Disease Control and Prevention (CDC), February 2018; the precise number of people affected by DVT/PE is unknown, although as many as 900,000 people could be affected (1 to 2 per 1,000) each year in the U.S.. Furthermore, increasing engagement of government healthcare regulatory bodies in developing and delivering effective and cost-effective low molecular weight heparin molecule products in the market is expected to propel the growth of the market. For instance, in 2014, American Society of Health-System Pharmacists (ASHP) issued the policy for safe and effective use of heparin in neonatal patients thereby supporting the development and use of nationally standardized concentrations of heparin when used for maintenance and flush of peripheral and central venous lines ...
A dialysis catheter is a catheter used for exchanging blood to and from a hemodialysis machine and a patient. The dialysis catheter contains two lumens: venous and arterial. Although both lumens are in the vein, the "arterial" lumen, like natural arteries, carries blood away from the heart, while the "venous" lumen returns blood towards the heart. The arterial lumen (typically red) withdraws blood from the patient and carries it to the dialysis machine, while the venous lumen (typically blue) returns blood to the patient (from the dialysis machine). Flow rates of dialysis catheters range between 200 and 500 ml/min. If a patient requires long-term dialysis therapy, a chronic dialysis catheter will be inserted. Chronic catheters contain a dacron cuff that is tunneled beneath the skin approximately 3-8 cm. The tunnel is thought to add a barrier to infection. The most popular dialysis catheter sold on the market today is the split-tip dialysis catheter. This catheter comprises two free floating ...
Cardiac tamponade secondary to a pericardial effusion. A rare but life-threatening complication of central venous catheters, including PICC and UVC. Incidence is 1% to 3%. Etiology is unclear, but proposed causes include a direct puncture of a vessel or myocardium (areas of weakness and incomplete muscularization may occur in neonates) by the catheter tip during insertion or delayed perforation secondary to erosion of the cardiac or vascular wall. Keep a high index of clinical suspicion in a neonate who has a central line and suddenly has cardiovascular collapse that does not respond to resuscitation or has resistance to external cardiac compressions and has no air leak by thoracic transillumination. Possible signs include hypotension, tachycardia, decreased/diminished heart signs, poor perfusion, decreasing arterial saturation, decreased heart sounds, increased jugular venous pressure (very difficult to assess in an infant), pulseless electrical activity with a central line, and pulsus ...
