Septicemia in dialysis patients: incidence, risk factors, and prognosis. (2/1510)

BACKGROUND: Infection is second to cardiovascular disease as a cause of death in patients with end-stage renal disease (ESRD), and septicemia causes a majority of these infectious deaths. To identify patients at high risk and to characterize modifiable risk factors for septicemia, we examined the incidence, risk factors, and prognosis for septicemia in a large, representative group of U.S. dialysis patients. METHODS: We conducted a longitudinal cohort study of incident ESRD patients in the case-mix study of the U.S. Renal Data System with seven years of follow-up from hospitalization and death records. Poisson regression was used to examine independent risk factors for hospital-managed septicemia. Cox proportional hazards analysis was used to assess the independent effect of septicemia on all-cause mortality and on death from septicemia. Separate analyses were performed for patients on peritoneal dialysis (PD) and hemodialysis (HD). RESULTS: Over seven years of follow-up, 11.7% of 4005 HD patients and 9.4% of 913 PD patients had at least one episode of septicemia. Older age and diabetes were independent risk factors for septicemia in all patients. Among HD patients, low serum albumin, temporary vascular access, and dialyzer reuse were also associated with increased risk. Among PD patients, white race and having no health insurance at dialysis initiation were also risk factors. Patients with septicemia had twice the risk of death from any cause and a fivefold to ninefold increased risk of death from septicemia. CONCLUSIONS: Septicemia, which carries a marked increased risk of death, occurs frequently in patients on PD as well as HD. Early referral to a nephrologist, improving nutrition, and avoiding temporary vascular access may decrease the incidence of septicemia. Further study of how race, insurance status, and dialyzer reuse can contribute to the risk of septicemia among ESRD patients is indicated.  (+info)

Acinetobacter bacteremia in Hong Kong: prospective study and review. (3/1510)

The epidemiological characteristics of 18 patients with acinetobacter bacteremia were analyzed. Patients (mean age, 55.5 years) developed bacteremia after an average of 14.1 days of hospitalization. Fifteen of 16 patients survived bacteremia caused by Acinetobacter baumannii. Cultures of blood from the remaining two patients yielded Acinetobacter lwoffii. Most patients (78%) resided in the general ward, while four patients (22%) were under intensive care. Genotyping by arbitrarily primed polymerase chain reaction analysis and the temporal sequence of isolation were more useful than phenotyping by antimicrobial susceptibility in the determination of the source of bacteremia, and the intravascular catheter was the leading infection source (39% of cases). The possibility of an association of glucose with the pathogenesis of acinetobacter infection was raised.  (+info)

Infective endocarditis due to Staphylococcus aureus: 59 prospectively identified cases with follow-up. (4/1510)

Fifty-nine consecutive patients with definite Staphylococcus aureus infective endocarditis (IE) by the Duke criteria were prospectively identified at our hospital over a 3-year period. Twenty-seven (45.8%) of the 59 patients had hospital-acquired S. aureus bacteremia. The presumed source of infection was an intravascular device in 50.8% of patients. Transthoracic echocardiography (TTE) revealed evidence of IE in 20 patients (33.9%), whereas transesophageal echocardiography (TEE) revealed evidence of IE in 48 patients (81.4%). The outcome for patients was strongly associated with echocardiographic findings: 13 (68.4%) of 19 patients with vegetations visualized by TTE had an embolic event or died of their infection vs. five (16.7%) of 30 patients whose vegetations were visualized only by TEE (P < .01). Most patients with S. aureus IE developed their infection as a consequence of a nosocomial or intravascular device-related infection. TEE established the diagnosis of S. aureus IE in many instances when TTE was nondiagnostic. Visualization of vegetations by TTE may provide prognostic information for patients with S. aureus IE.  (+info)

Validation of haemodialysis recirculation and access blood flow measured by thermodilution. (5/1510)

BACKGROUND: Recirculation (R) and access blood flow (Qac) measurements are considered useful indicators of adequate delivery of haemodialysis. It was the purpose of this study to compare measurements of R and Qac obtained by two different techniques which are based on the same principle of indicator dilution, but which differ because of the characteristics of the injection and detection of the different indicators used. METHODS: Recirculation measured by a thermal dilution technique using temperature sensors (BTM, Fresenius Medical Care) was compared with recirculation measured by a validated saline dilution technique using ultrasonic transducers placed on arterial and venous segments of the extracorporeal circulation (HDM, Transonic Systems, Inc.). Calculated access flows were compared by Bland Altman analysis. Data are given as mean +/- SD. RESULTS: A total of 104 measurements obtained in 52 treatments (17 patients, 18 accesses) were compared. Recirculation measured with correct placement of blood lines and corrected for the effect of cardiopulmonary recirculation using the 'double recirculation technique' was -0.02 +/- 0.14% by the BTM technique and not different from the 0% measured by the HDM technique. Recirculation measured with reversed placement of blood lines and corrected for the effect of cardiopulmonary recirculation was 19.66 +/- 10.77% measured by the BTM technique compared with 20.87 +/- 11.64% measured by the HDM technique. The difference between techniques was small (-1.21 +/- 2.44%) albeit significant. Access flow calculated from BTM recirculation was 1328 +/- 627 ml/min compared with 1390 +/- 657 ml/min calculated by the HDM technique. There was no bias between techniques. CONCLUSION: BTM thermodilution yields results which are consistent with the HDM ultrasound dilution technique with regard to both recirculation and access flow measurement.  (+info)

Right atrial bypass grafting for central venous obstruction associated with dialysis access: another treatment option. (6/1510)

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)

A method for collecting right coronary venous blood samples from conscious dogs. (7/1510)

This report describes for the first time a technique to collect right coronary venous blood samples from conscious dogs. Catheters, prepared from Micro-Renathane tubing, were surgically implanted in right ventricular superficial veins of three anesthetized dogs. Also implanted were an arterial catheter, a right coronary flow transducer, and a right coronary artery constrictor. The coronary catheter was introduced at a venous bifurcation so that its side holes were positioned above the bifurcation; both ends of the catheter were exteriorized. Heparinized saline was continuously infused through the venous catheter by a battery-powered pump. The dogs were maintained for 10-13 days after surgery, and all catheters remained patent. Multiple right coronary venous samples were collected from each dog. These samples were analyzed for venous oxygen tension (PvO2) under baseline conditions, with right coronary pressure reduced to 50 mmHg, and during the reactive hyperemia after release of the right coronary artery constriction. PvO2 was 27.7 +/- 1.0 mmHg at baseline, 23.4 +/- 1.0 mmHg during coronary artery constriction, and 34.3 +/- 1.5 mmHg during reactive hyperemia. These data and the position of the catheter at autopsy demonstrated that coronary venous blood had been sampled.  (+info)

Volume flow measurement in hemodialysis shunts using time-domain correlation. (8/1510)

Volume flow was measured in 58 hemodialysis shunts (32 grafts and 26 radial fistulas) using the color velocity imaging-quantification method. This method is based on time-domain correlation for velocity calculation and integration of time-varying velocity profiles generated by M-mode sampling. Measurements were made in the brachial artery to estimate radial fistula flow or directly in the grafts. Intraoperator reproducibility was 14.9% for fistulas and 11.6% for grafts. Flow rate was significantly lower in abnormal shunts associated with a functional disorder or a morphologic complication (808 ml/min +/- 484) than in shunts associated with no abnormalities (1401 ml/min +/- 562). Receiver operating characteristic curves showed that a flow rate of 900 ml/min for fistulas and 1300 ml/min for grafts provided 81% and 79% sensitivity and 79% and 67% specificity, respectively. A functional disorder or a morphologic complication was associated with all fistulas and grafts in which flow rates were lower than 500 ml/min and 800 ml/min, respectively.  (+info)

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 ...

BACKGROUND: We investigated the safety and efficacy of several dosing regimens of catheter-directed staphylokinase (SY162) bolus administration for the treatment of long-term venous access catheter occlusion. METHODS: This open-label, ascending dose study enrolled 24 subjects. Three doses of SY162 were evaluated in three cohorts (0.15 mg, 0.3 mg and 0.45 mg) with eight subjects each. Catheter function was evaluated 30 min after the first bolus administration. In case of incomplete catheter function restoration, a second bolus was administered with reassessment of catheter function 30 min thereafter. Cathetergram was repeated to assess thrombus resolution. RESULTS: Complete restoration of catheter withdrawal function was observed in 2 (25%), 1 (13%) and 7 (88%) subjects after the first bolus in the first, second and third cohort respectively and in 4 (50%), 7 (88%) and 7 (88%) patients after the second administration of SY162. There were no bleeding complications nor other adverse events related ...

In this secondary analysis of the ELVIS study, we found that inserting a DC by GWE (as opposed to VPI) did not increase the risk of DC colonization but was associated with a higher risk of DC dysfunction. The risk of DC dysfunction was more than twofold higher when the previous DC was malfunctioning and had been replaced by GWE rather than by VPI.. In a pilot study Palmer et al. demonstrated that guidewire contamination during central line placement predisposes to subsequent colonization of the inserted catheter [19]. This is why replacement by GWE of a non-tunnelled catheter that is suspected to be infected is discouraged, but it may be used to replace a malfunctioning catheter when there is no evidence of catheter infection [14].. Three recent observational studies of critically ill adult patients, designed to assess the impact of catheter replacement by GWE on the risk of infections, yielded conflicting results [20-22]. In a prospective multicentre survey of 1598 central venous catheters, ...

A tunneled catheter remains the most common access in patients initiating haemodialysis.1 This is most likely because the catheters are ready to use immediately after insertion, with no maturation time needed. As with any other dialysis access, hydraulic performance is critical for tunneled catheters. This depends mainly on the exit site, the shape of the catheter curve, and the tip position. In this report, Mohamed A Sheta and John R Ross discuss one important technical issue: the catheter tip.. In 2006, the Kidney Disease Outcomes Quality Initiative recommended that "at the time of placement, the tip(s) of the catheter should be in the mid-atrium, with the arterial lumen facing the mediastinum."2 In one study, Mandolfo et al reported better blood flow with the catheter tip in the right atrium.3 In another study by McCarthy, the mean survival of catheters in the right atrium was 245 days, but only 116 days for catheters placed at the junction of the superior vena cava and the right atrium.4 ...
The catheter tip must be in the lower superior vena cava for optimal performance. If placed femorally, the catheter tip should be placed in the inferior vena cava to minimize recirculation. Catheters greater than 24 cm are intended for femoral vein insertion. CAUTION: For jugular and subclavian insertion, the catheter tip should not be located in the right atrium.. WARNING: Verification of the catheter tip location must be confirmed by x-ray.. ...

BACKGROUND: Catheter-related infection (CRI) is associated with increased all-cause mortality and morbidity in hemodialysis patients and may be reduced by using antimicrobial lock solutions (ALSs). STUDY DESIGN: We performed a meta-analysis of studie
A catheter for hemodialysis comprises a flexible catheter tube defining a plurality of separate lumens. The catheter defines an arc angle of generally U-shape in its natural, unstressed configuration. Thus, the catheter may be implanted with a distal catheter portion residing in a vein of the patient, the distal catheter portion being of substantially the shape of the vein in its natural, unstressed condition. Also, a proximal catheter portion resides in a surgically created tunnel extending from the vein and through the skin of the patient, this section of the Catheter also being typically in its natural, unstressed condition. Thus blood may be removed from the vein through one lumen of the catheter, and blood may be returned to the vein through another lumen of the catheter, while the catheter is subject to long term indwelling in the body. Improved results are achieved because of the lack of mechanical stress in the shape of the catheter, which stress causes the catheter to press unduly against
A number of past conventional meta-analyses have compared different ALS with heparin. However, there is no consensus recommendation regarding which type of ALS is best. The purpose of our study is to carry out a network meta-analysis comparing the efficacy of different ALS for prevention of CRI in patients with HD and ranking these ALS for practical consideration.. METHODS AND ANALYSIS: We will search six electronic databases, earlier relevant meta-analyses and reference lists of included studies for randomised controlled trials (RCTs) that compared ALS for preventing episodes of CRI in patients with HD either head-to-head or against control interventions using non-ALS. Study selection and data collection will be performed by two reviewers independently. The Cochrane Risk of Bias Tool will be used to assess the quality of included studies. The primary outcome of efficacy will be catheter-related bloodstream infection (CRBSI). We will perform a Bayesian network meta-analysis to compare the ...
Although Hickman catheters provide safe and reliable venous access for chemotherapy over many months (1, 2), infectious complications (3, 4) and the need for sophisticated and attentive care to maintain patency of the catheter for the duration of therapy (5) have encouraged the development of alternative devices. Access ports have recently been introduced (6, 7) to avoid these problems of maintenance and sepsis. The ports are implanted subcutaneously and have a small reservoir attached to the external end of the venous access tubing. Entry to the device for drug administration is gained by directing a specially designed needle through the ...
A. A central line is a device that assists in the process of administering chemotherapy and other medications and fluids, and blood sampling. A tube is surgically placed into a blood vessel. This device avoids the need for separate needle insertions for each infusion or blood test. Examples of these devices include Hickman or Broviac catheters, PICC lines and ports. Hickman or Broviac catheters are placed in the upper chest, and there is an external portion that protrudes from the skin. PICC lines are placed in the arm, and also have an external portion. Ports are placed in the chest but are implanted below the skin, so that nothing shows externally. When a Broviac, Hickman or PICC line are accessed, a syringe is attached to the external portion in a painless procedure. When a port is accessed, the needle is inserted through the skin causing a brief moment of discomfort, minimized with the use of a special cream (EMLA) applied to the skin. ...

Methods for making a loaded catheter assembly for delivering a self-expanding stent where the self-expanding stent is carried in a compressed state and the compressed stent has an inside diameter smaller than the outside diameter of the catheter distal tip. The methods can utilize catheter sub-assemblies lacking already attached tips or having partially formed distal tips. A stent can be proximally and co-axially slid over the distal end of the catheter shaft and constrained by a retractable sheath disposed co-axially about the compressed stent. The catheter distal tip can be added or more fully formed after the loading of the stent. Some catheters include a preformed distal conical tip held in position by a heat-shrink film. Other catheters have an elastomeric distal tip waist for slipping over and engaging an outward projection on the catheter shaft distal region. Some catheters are adapted to engage catheter shaft distal threaded regions.

Many different risk factors for CRI in intensive care patients have been reported in the literature [3, 4, 8, 9, 11-13]. These include insertion site, duration of catheterization, type of dressing, type of catheter, frequent manipulations, improper aseptic techniques, number of catheter lumens, type of topical antiseptic solution used and use of the catheter for TPN. The relative importance of one risk factor over another is diffucult to assess given that in most studies only univariate analysis has been performed and estimates of the risk of each factor has not been attempted. We performed a logistic regression to assess the major determinants of CRI and found that the independent predictors of CRI were catheter insertion site, duration of catheterization and antibiotic (glycopeptide) usage.. In our study infection rates of catheters inserted into jugular vein and subclavian vein were 22.7%, 11.9% respectively (p = 0.005). The CVCs inserted to the jugular vein were associated with approximately ...

A sliding gas-tight seal on an access port promotes insufflation of an anatomical space formed in tissue at a surgical site only during insertion of an endoscopic instrument through the access port into the anatomical space, and promotes deflation of the inflated space upon removal of the endoscopic instrument from within the access port. An inflatable balloon disposed about the port near the distal end may be selectively expanded to seal and anchor the access port within an incision through which a surgical procedure with insufflation is to be performed. Multiple resilient seals may be attached to the body of the port, and an auxiliary resilient seal may be inserted within the aperture of a seal attached to the body to accommodate a wide range of endoscopic instruments of various exterior dimensions inserted through the seals.
A hemodialysis catheter comprising a dual lumen tube with a bullet nose bolus at its distal end. A venous port is formed in one side of the bolus adjacent the bullet nose of the bolus. An arterial port is formed in the bolus circumferentially displaced 180 around the catheter from the venous port. The bolus contains a venous passage which transitions from a smaller diameter D-shaped cross-section to a larger diameter circular cross-section. The bullet nose is thinner than the tube but is inclined on an angle to the axis of the tube so that a portion of its outer periphery is substantially tangent to a hypothetical cylinder containing the trailing edge of the venous port.
Patients who undergo hemodialysis via a tunneled catheter often develop bloodstream infections that arise from the catheter. There are several management options for treatment of such an infection, though the best option is not clearly delineated. Standard of care options include exchanging the catheter for a new one over a guide-wire and instilling a high concentration of an antibiotic directly into the catheter lumen. The investigators are planning to treat hemodialysis catheter bloodstream infections by one of two strategies: 1. Use of a novel antibiotic lock solution Or 2. Changing out the infected catheter for a new one. Both these options have comparable cure rates as shown in the medical literature. After obtaining informed consent, patients will be randomized to either treatment arm and will continue to receive all other standard medical care.. Specific Aim: To conduct a randomized clinical trial to demonstrate that the use of a novel antibiotic lock solution (consisting of ...
Retrograde placement allows the placer to position the catheter tip in the desired anatomical location before creation of the tunnel tract. This differs from antegrade placement where the catheter tip is placed in the desired location after creation of the tunnel tract. As a result, retrograde placement may allow for more accurate tip placement.. ...
Intermittent catheters are used for emptying the urinary bladder in patients who lose control over their bladder. These catheters are used for short term. Urine incontinence can be caused due to neurogenic bladder disorders such as spinal cord injury, spina bifida or multiple sclerosis, and non-neurogenic bladder disorders. The catheter is inserted into the urethra and guided to the bladder causing the urine to flow through the catheter tube and drain into the collection bag. Once the bladder is emptied, the catheter can be removed. Self- catheterization is also possible with these catheters; even children of seven or eight years can be trained to handle catheterization on their own. A parent or caregiver can help in case a patient is physically ill.. The analysts forecast the Global Intermittent Catheters Market to grow at a CAGR of 6.33 percent over the period 2015-2019.. The report covers the present scenario and the growth prospects of the Global Intermittent Catheters market for the period ...

The standard procedure for maintaining patency between dialysis treatments, the instillation of heparin into the lumens in a volume sufficient to fill to the lumen tip (the lock) is being replaced by the substitution of a trisodium citrate (TSC) 4 percent lock at many centers. One large Canadian study (6) showed a lower rate of TDC exchange and tissue plasminogen activator (tPA) use without a change in hospitalization for TSC 4 percent versus heparin. On the basis of available evidence, the American Society of Diagnostic and Interventional Nephrology Clinical Practice Committee (7) recommends using a locking solution of heparin 1000 U/mL or TSC 4 percent to maintain TDC patency.. Although a larger-bore catheter design allows an initial rate of blood flow above 400 mL/min to be achieved, virtually all catheters show eventual flow dysfunction manifested as progressive blood flow reductions at prepump pressures considered safe: 200-250 mm Hg.. Prospective monitoring for blood flow dysfunction ...

Although the 5-F catheter is reputed to cause less vascular trauma than larger catheters, subintimal injections of contrast material have occurred following intimal damage by the catheter tip. Microscopic studies of the tips of two widely used 5-F polyethylene catheters have revealed a difference in configuration resulting in one of the catheters becoming markedly damaged during angiography. The authors make recommendations for finishing and protecting the catheter tip. ...
The construction of realistic simulators for medical procedures is increasingly important. We describe here a physical model and a numerical algorithm to simulate the insertion and navigation of a catheter into an arterial system. A novel formulation of the elasticity of thin rods was developed for modeling the catheter. The catheter bends and twists within the blood vessels, not simply tracking a central curve. The inner artery walls are modeled as rigid surfaces; this constraint of catheter containment within rigid walls is implemented through the use of a wall potential. The model has been integrated into an interactive system, with visualization and a direct catheter input interface (previously described), called da Vinci (Visual navigation of catheter insertion). © 2000 Elsevier Science Ltd.

A dilatation catheter is provided with an inflatable section which in its non-inflated condition may have a diameter several times that of the balance of the catheter. Means are provided to axially twist the inflatable part of the catheter to reduce its diameter in its non-inflated condition to a size comparable to that of the non-inflatable balance of the catheter so that the catheter may be threaded through and positionally emplaced within a blood vessel.
Of the desirable characteristics of an ideal vascular access device for dialysis, the most important is a high blood flow rate (up to 400-500ml for intermittent haemodialysis). It should be constructed of a biologically inert non-immunogenic material to improve tolerance, and it should be resistant to kinking and thrombotic occlusion. The catheter should be designed in a way which decreases the amount of recirculation (i.e. purified blood being sucked back into the filter).

To assess retrospectively the duration of functioning, rate and reason of complications and explantations, 230 totally implantable venous access systems (133 chest ports and 97 arm ports) implanted between 1995 and 1998 at the clinic of oral surgery of the Hospital Rechts der Isar (Technical University Munich) have been analysed. The observed complications have been classified and recommendations have been defined how to reduce the complication rates. The explantation rate due to complications (infection and deep venous thrombosis) was 12,2 % or 0,378 per 1.000 patient days and therefore better than the figures reported in literature (0,408 explantations per 1.000 patient days). It may be concluded that complications in these days are mainly subject to clinical management. For this reason general guidelines for an integrated port management (prophylaxis, nursing and control, diagnosis and therapy) for infectious and thrombotic complications after the implantation of central venous subcutaneous ...

Gleason7 - Until I hit Catheter 15, I had never had one block up or plug, so its not normal. #15 plugged up twice, the first time my wife was able to clear it, the 2nd time, I had to rushed to my uros office, and his asst. couldnt clear it so they swapped it. Since my radiation ended in late November, my leg/night bags have often had blood and bloody debris in with the urine. They feel that some of that is probably related to colateral damage from the radiation, and some of it is from the two corrective surgeries I had at the bladder neck, one in January, and one in March. The inlet to the catheter sits just above the balloon inside the blader, and the inlet holes are actually tiny when you see them up close. I can only guess that just by chance, debris too big to clear the inlets sits in the way and blocks. WHen the catheter is irragated, it flushes sterile water through the cath and into the bladder. This is done 1 - 3 times, to clear the debris ...
