Endovascular repair of a descending thoracic aortic aneurysm: a tip for systemic pressure reduction. (1/550)

A proposed technique for systemic pressure reduction during deployment of a stent graft was studied. A 67-year-old man, who had a descending thoracic aneurysm, was successfully treated with an endovascular procedure. An occluding balloon was introduced into the inferior vena cava (IVC) through the femoral vein. The balloon volume was manipulated with carbon dioxide gas to reduce the venous return, resulting in a transient and well-controlled hypotension. This IVC-occluding technique for systemic pressure reduction may be safe and convenient to minimize distal migration of stent grafts.  (+info)

Risk of clot formation in femoral arterial sheaths maintained overnight for neuroangiographic procedures. (2/550)

BACKGROUND AND PURPOSE: The purpose of this study was to evaluate the presence of blood clots in femoral arterial sheaths maintained after cerebral angiography and the effect of heparinized saline on clot formation. METHODS: Twenty-three sheaths were evaluated in 18 patients. Sheaths were maintained for 14 to 80 hours (average, 33 hours; median, 24 hours). After the sheaths were removed, they were vigorously flushed with 60 mL of normal saline and the number and size of clots found in each sheath were recorded. Additionally, patients' age, catheter size, presence of heparin, amount of time the sheath was kept in the artery, and patients' coagulation status were recorded. RESULTS: Clots were found in 17 (74%) of the 23 sheaths. Ten catheters had continuous heparin drip, of which seven (70%) sustained clots. Of the 13 sheaths without heparin, 10 sustained clots (77%). The difference was not statistically significant. The average number of clots was 2.2, and the maximal length of clots ranged from 0.5 to 105 mm. No thromboembolic complications associated with sheath placement were encountered in our patient population. CONCLUSION: Blood clots are present in the vast majority of intraarterial sheaths maintained after cerebral angiography. These clots constitute a risk of thromboembolic complications in the event of repeat angiography. Sheath exchange should be considered before obtaining repeat cerebral angiograms.  (+info)

An unusual cutaneous manifestation of myelodysplastic syndrome: "pseudo-Koebner phenomenon". (3/550)

An unusual and hitherto unreported complication of myelodysplastic syndrome is reported: the "pseudo-Koebner phenomenon." The skin lesions were characterised by exuberant "fleshy" masses at the sites of intravenous cannulation and skin trauma, and by histological evidence of chronic inflammation with focal necrosis and abscess formation. No evidence of dermal infiltration by malignant haemopoietic cells was seen. The exact aetiopathology of the phenomenon is unclear but an inappropriate and exaggerated inflammatory response owing to aberrant mediator mechanisms that are known to occur in some cases of myelodysplastic syndrome may be implicated.  (+info)

A reexamination of the angiotoxicity of superselective injection of DMSO in the swine rete embolization model. (4/550)

BACKGROUND AND PURPOSE: There are a variety of embolization applications for non-adhesive, liquid agents. We reevaluated the potential microvascular angiotoxicity of superselective infusions of dimethyl sulfoxide (DMSO) using very long infusion rates in a previously described animal model. METHODS: Twenty-six swine underwent percutaneous femoral puncture for superselective catheterization of the artery of the rete while being continuously monitored for ECG and intraarterial pressure. Two volumes (0.5 or 0.8 mL) and three durations (30, 60, and 90 seconds) of superselective infusion of DMSO were used to evaluate the effect of a single-dose rate within an ipsilateral rete. Contralateral control infusions of normal saline were also administered. Acute hemodynamic and angiographic outcomes were assessed. After recovery, follow-up angiography and sacrifice were performed at either 10 or 28 days. Brains and retia were harvested for gross and microscopic histopathologic evaluation. RESULTS: No significant hemodynamic alterations occurred acutely. Twenty-three of the 24 infused retia showed variable acute vasospasm that typically was mild to moderate in severity and transient (10 to 20 minutes). Follow-up angiography at sacrifice always showed normal retial arterial anatomy. No adverse clinical sequelae were noted. Gross inspection of brains showed no evidence of infarction or subarachnoid hemorrhage. Microscopic histopathologic examination of retia showed mostly nonspecific changes in both exposed and control samples. Possible causal histotoxicity was seen in four retia (three of four exposed to higher dose rates), in which involvement was limited to one to three retial arteries. CONCLUSION: Lower total dose and dose rates of superselective infusion of DMSO into the retial microarterial network resulted in substantially less angiotoxicity than that found in a previous study, as defined by clinical, angiographic, gross, and histopathologic criteria.  (+info)

Superselective intraarterial fibrinolysis in central retinal artery occlusion. (5/550)

Intraarterial fibrinolysis was performed in three patients with acute central retinal artery occlusion using recombinant tissue plasminogen activator as a fibrinolytic agent. In two cases the ophthalmic artery was selectively catheterized, and in the other a thrombolytic drug was infused into the ophthalmic artery by way of the meningeal collaterals. All patients experienced visual improvement. Fibrinolysis can produce better results than obtained from conservative treatment. A good prognosis can be achieved if the treatment starts within the first 4 to 5 hours after occlusion.  (+info)

Application of a rheolytic thrombectomy device in the treatment of dural sinus thrombosis: a new technique. (6/550)

We present a novel application of a transvascular rheolytic thrombectomy system in the treatment of symptomatic dural sinus thrombosis in a 54-year-old woman with somnolence and left-sided weakness. The diagnosis of bilateral transverse and superior sagittal sinus thrombosis was made and the patient was treated with anticoagulant therapy. After an initial period of improvement, she became comatose and hemiplegic 8 days after presentation. After excluding intracerebral hemorrhage by MR imaging, we performed angiography and transfemoral venous thrombolysis with a hydrodynamic thrombectomy catheter, followed by intrasinus urokinase thrombolytic therapy over the course of 2 days. This technique resulted in dramatic sinus thrombolysis and near total neurologic recovery. Six months after treatment, the patient showed mild cognitive impairment and no focal neurologic deficit. Our preliminary experience suggests that this technique may play a significant role in the endovascular treatment of this potentially devastating disease.  (+info)

Pharmacokinetic advantage of intra-arterial cyclosporin A delivery to vascularly isolated rabbit forelimb. I. Model development. (7/550)

Effective antirejection therapy with minimal systemic morbidity is required if limb transplantation is to become a clinical reality. We investigated whether i.a. infusion of cyclosporin A (CSA) into the vascularly isolated rabbit forelimb will distribute drug homogeneously to the tissues and produce higher local drug levels than same-dose i.v. treatment, thereby improving the therapeutic index. CSA 4.0 mg/kg/day was infused continuously via osmotic minipump into either the right brachial artery (i.a. group) or jugular vein (i.v. group) of New Zealand rabbits. Ligation of all muscles at the right mid-arm level was performed in the i.a. group to eliminate collateral circulation and simulate allografting, while leaving bone and neurovasculature intact. On day 6, CSA concentrations were measured in skin, muscle, bone, and bone marrow samples taken from different compartments of the right and left forearms in the i.a. group and right forearm only in the i.v. group. There were no significant differences between compartmental CSA levels in all tissues examined on the locally treated, right side during i.a. infusion, indicating that drug streaming from the catheter tip is not occurring in our model. During i.a. infusion, mean CSA concentrations were 4- to 7-fold higher in the right limb than in the left limb in all four tissues examined. Tissue CSA levels in the left limb were equivalent to those achieved during i.v. infusion, but CSA concentrations in blood, kidney, and liver were higher during i.a. infusion. These favorable, preliminary, single-dose pharmacokinetic results warrant further investigation in our novel rabbit model.  (+info)

Pharmacokinetic advantage of intra-arterial cyclosporin A delivery to vascularly isolated rabbit forelimb. II. Dose dependence. (8/550)

A vascularly isolated rabbit forelimb model simulating conditions of composite tissue allografting was used to determine the regional pharmacokinetic advantage achievable in extremity tissue components during i.a. cyclosporin A (CSA) administration. CSA was infused continuously via osmotic minipump into the right brachial artery of New Zealand rabbits at multiple doses ranging from 1.0 to 8.0 mg/kg/day. On day 6, CSA concentrations were measured in aortic whole blood, as well as in skin, muscle, bone, and bone marrow samples from both right and left forelimbs. The variation of right-sided mean CSA concentrations with dose was tissue dependent and saturable in the case of skin and bone, whereas left-sided tissue concentrations correlated significantly with systemic blood levels. At 1.0 mg/kg/day, there were no significant differences between right and left mean CSA concentrations for all four tissues examined. However, with a doubling of the i.a. dose, huge increases in local tissue CSA concentrations were produced with only very modest increases in systemic whole-blood and tissue drug levels, resulting in a 4-fold regional advantage (right/left ratio of CSA concentrations) in bone and bone marrow, 7-fold in muscle, and 14-fold in skin. With further dose increases to 8.0 mg/kg/day, the regional advantage decreased to 4-fold in skin, increased to 9-fold in bone marrow, remained relatively constant in bone, and initially decreased and then increased to 9-fold in muscle. These favorable pharmacokinetic results suggest that reduced, local doses of CSA might be useful in preventing extremity composite tissue allograft rejection with decreased systemic drug exposure.  (+info)

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. ...
A peripherally inserted central catheter (PICC or PIC line), less commonly called a percutaneous indwelling central catheter, is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g., antihypotensive agents a.k.a. pressors). It is a catheter that enters the body through the skin (percutaneously) at a peripheral site, extends to the superior vena cava (a central venous trunk), and stays in place (dwells within the veins) for days or weeks. First described in 1975, it is an alternative to central venous catheters in major veins such as the subclavian vein, the internal jugular vein or the femoral vein. Subclavian and jugular line placements may result in pneumothorax (air in the pleural space of lung), while PICC lines have no such issue because of the method of placement. In those who are very ...
A peripherally inserted central catheter (PICC), or PICC line, is a catheter that is placed in the antecubital vein (a large vein in the inner elbow area). It is threaded through the vein into or near the right atrium of the heart.

Peripheral inserted central catheters (PICCs) have increasingly become the mainstay of patients requiring prolonged treatment with antibiotics, transfusions, oncologic IV therapy and total parental nutrition. They may also be used in delivering a number of other medications to patients. In recent years, bed occupancy rates have become hugely pressurized in many hospitals and any potential solutions to free up beds is welcome. Recent introductions of doctor or nurse led intravenous (IV) outpatient based treatment teams has been having a direct effect on early discharge of patients and in some cases avoiding admission completely. The ability to deliver outpatient intravenous treatment is facilitated by the placement of PICCs allowing safe and targeted treatment of patients over a prolonged period of time. We carried out a retrospective study of 2,404 patients referred for PICCs from 2009 to 2015 in a university teaching hospital. There was an exponential increase in the number of PICCs requested ...
The aim of this study was to identify factors that contribute significantly to the bacterial contamination of peripheral intravenous catheters in dogs and cats.

Abstract:. BACKGROUND: Despite the popularity of peripherally inserted central catheters (PICCs), recent literature highlights their potential injurious complications. Innovative PICC materials have been developed to prevent thrombosis and infection formation (Endexo®) and antireflux valves to prevent occlusion (pressure-activated safety valve®). No large randomized controlled trial has assessed these technologies. Our primary aim was to evaluate the feasibility of a large randomized controlled efficacy trial of PICC materials and design to reduce PICC complication in pediatrics.. METHODS: A randomized controlled feasibility trial was undertaken at the Lady Cilento Childrens Hospital in South Brisbane, Australia, between March 2016 and November 2016. Consecutive recruitment of 150 pediatric participants were randomly assigned to receive either (1) polyurethane PICC with a clamp or (2) BioFlo® PICC (AngioDynamics Inc, Queensbury, NY). Primary outcomes were trial feasibility, including PICC ...

The Article: Bugden S, et al. Skin Glue Reduces the Failure Rate of Emergency Department-Inserted Peripheral Intravenous Catheters: A Randomized Controlled Trial. Ann Emerg Med. 2016;1-6.. The One-Liner: Skin glue, in addition to standard care securement, may reduce peripheral intravenous catheter failure rates at 48 hours for admitted patients after insertion in the ED.. Background: Frequently initiated in the ED setting, peripheral intravenous (IV) catheters may fail with inadequate fixation serving as the underlying etiology in infection, phlebitis, occlusion, or dislodgement. Failure disrupts hydration, antibiotic therapy, and analgesia for the patient, and incurs the added costs of additional supplies and staff time. In comparison to standard polyurethane dressings, medical-grade skin glue (cyanoacrylate) in addition to a dressing has been proven to be more effective in securing central venous, epidural, and peripheral arterial catheters.

ALBANY, N.Y., June 12, 2013-- AngioDynamics, a leading provider of innovative, minimally invasive medical devices for vascular access, surgery, peripheral vascular disease and oncology, announced that its BioFlo peripherally inserted central catheter was one of 14 medical innovations on display in front of thousands of healthcare providers and experts at the Premier healthcare alliances 2013 Breakthroughs Conference and Exhibition.
Caroline is still wearing a designer nasal canula (Im not sure if its Coach or LV, but its sooo this season) and its on about the lowest setting available. The remaining belly tube has a mandatory removal date sometime in the next 24-48 hours, but thats good and bad. The belly line has to come out because its at risk for an infection, but she still needs a line in for fluids, meds and food. If it were just fluids and meds, then an IV would work, but the food is a different story... so theyll soon have to insert a PICC line. A PICC line is a Peripherally Inserted Central Catheter. Its basically an IV that gets inserted into a vein in your upper left arm and pushed up near your heart. Food (or rough drugs) causes the small veins to collapse easily, so this will keep her from having to be stuck with a needle over and over again. It kinda stinks because it makes holding her a little more difficult, but its needed. Theyll put that intomorrow or Tuesday ...
OBJECTIVE: The etiology of necrotizing enterocolitis (NEC) remains elusive despite known associations with several factors, including intestinal ischemia related to the effects of umbilical arterial catheterization on the mesenteric circulation. However, the role of the mesenteric venous circulation has yet to be studied as a potential cause of NEC. We examined the association between umbilical venous catheter (UVC) position and the development of NEC in prematureinfants. ...
Peripheral intravenous catheters (or IVs) are the mainstay for providing therapies in modern medicine. Yet approximately 90 million people each year require multiple attempts to establish IV access. These extra attempts result in increased hospital cost associated with employee time, additional patient discomfort, and delays in delivering important therapies. Currently IV catheters rely upon blood return and they do not assist with advancing the catheter into the vein. ThreadRite is a modified standard catheter that immediately alerts clinicians to vein entry. It also employs a guidewire to help clinicians thread the IV right into the vein. ThreadRite will reduce patient pain as well as provider costs associated with this common problem.. ...

Background: Peripheral intravenous catheters (PIVCs) are the most widely used invasive devices among inpatients. Catheter-related bloodstream infections (CRBSI) are serious yet preventable events for patients. Although the contribution of PIVCs towards these infections is gradually being recognised, its role in the Spanish setting is yet to be determined. We aimed to estimate the rate and incidence of PIVC failure at Manacor hospital (Spain) as baseline within a wider quality improvement initiative. Methods: Tips from all PIVC removed during December 2017 and January 2018 in hospital wards were cultured semiquantitatively. The study population included all PIVCs inserted in adult patients admitted to any of three medical and one surgical wards, emergency department, critical care unit and operating rooms. Clinical, microbiological and ward information was collected by clinical researchers for each PIVC from insertion to removal on the study sites. CRBSI was defined per international guidelines ...

Those who manage the anesthetic care of children who need an arterial line know that insertion can be difficult. The pulse is felt, yet pass after pass fails to cannulate the artery. Ultrasound guidance is becoming more popular, particularly for difficult arterial cannulation.. Dr. Yoshinobu Nakayama, Department of Anesthesiology and Intensive Care, Kyoto Prefectural University of Medicine, Kyoto, Japan, and colleagues first determined factors that predicted ultrasound-guided percutaneous radial arterial catheterization in children and then used the strongest predictor of success as the basis of a randomized trial. Their results are presented in this months Anesthesia & Analgesia in the article "A Novel Method for Ultrasound-Guided Radial Arterial Catheterization in Pediatric Patients.". The authors used the Sonosite M-Turbo® ultrasound system. The arterial catheter was a 24 gaugeJelco® Plus catheter. The authors considered 102 patients in the initial assessment phase. A subcutaneous arterial ...
Background: Peripheral venous catheter (PVC) insertion is a crucial nursing action during life support. Several factors that increase the risk of thrombophlebitis associated with PVCs have been reported. Objective: We wish to evaluate the impact of a quality improvement regarding PVC treatment for patients with coronary heart diseases.. Method: A longitudinal, quantitative observational study was carried out in 2008 and 2013 in a hospital in southern Sweden with 360 consecutive patients suffering from acute chest pain. New routines for PVC treatment were included in the hospital with daily inspection according to a checklist. A structured observation protocol was used to survey the prevalence of thrombophlebitis between 2008 and 2013. Also, we examined the relationship between the location and luminal diameters of PVCs.. Results: The students t-test showed significant differences between 2008 and 2013 with respect to luminal diameter of PVCs (p = 0.002), prevalence of thrombophlebitis (p = ...
How to Insert a Cannula. Intravenous (IV) cannulation, also known as insertion of a peripheral venous catheter (PVC), is a fairly straightforward medical procedure. However, it does take some technique and preparation to complete safely....
The technique of blood samples extraction from the radial artery through an arterial catheter with a 3-way stopcock and automated washing with valve of fast flow is better than the one carried out through a fixed reusable arterial blood sample syringe and its manual washing because it shows a minor incidence of the complications originated from technical manipulation as infection, pseudo-aneurysm, ischemia or thrombosis of radial artery or obstruction of the catheter.. The purpose of this study is to evaluate the efficacy, in terms of adverse effects, of blood samples obtention using an arterial catheter with needless connector closed system or an arterial catheter with an arterial blood sample syringe.. Also a second purpose is to compare once a day (at the same time) the values of glycose blood levels between bedside glucometer determination of arterial catheter extraction and capillar puncture, and lab determination of glycose from venous puncture, in order to determinate fluctuation in ...

BACKGROUND: 12-lead ECG monitoring of the ST segment is more sensitive than patients symptoms for detecting ischemia after thrombolytic therapy or catheter-based interventions, but it is unclear whether monitoring of the single lead showing maximum ST deviation would be as efficacious. OBJECTIVE: To determine whether monitoring all 12 ECG leads for changes in the ST segment is necessary to detect ongoing ischemia in patients with unstable coronary syndromes. METHODS: Continuous 12-lead ST segment monitoring was performed in 422 patients from the onset of myocardial infarction or during balloon inflation in catheter-based interventions until the patients discharge from the cardiac care unit. Computer-assisted techniques were used to determine (1) which lead showed the maximum ST deviation at the onset of myocardial infarction or during balloon inflation and (2) what proportion of later ischemic events were associated with ST deviation in this lead. RESULTS: The lead with the maximum ST ...

We recently had an incident of an arterially placed PICC discovered after several weeks of treatment.The nurse who dcd the PICC noticed pulsing of blood from the insertion site after removal of the catheter.  A few days later, another nurse noticed on the x-ray film that the path of the PICC wasunusual...both of these films showed the catheter rising above the level of the clavicle and crossingthe midline, rather than dropping down into the SVC. Both these PICCs were placed in the rightarm. We(PICC nurses) view our PICC x-rays and release them for use...the really interesting thing was that in both cases,
There are different types of cannulation practiced in medical processes. Following are the most common:. Intravenous (IV) Cannulation. IV Cannulation is a technique of placing a cannula inside a vein to gain venous access. The primary function of IV is administration of intravenous fluids and medicine. Blood samples can also be obtained through this type of cannulation. Arterial cannula is used in major operations and critical care areas to draw multiple blood samples at different times.. Nasal/Oral Cannulation. A flexible tube when inserted into the nostrils/mouth to deliver oxygen, anesthesia. Its also used to measure airflow into and out of the nose/mouth. Nasal cannulas usually have multiple short, open-ended branches to facilitate insertion.. Purpose of Cannulation. As mentioned earlier, cannulation is process through which bodily fluids are either removed or added into ducts carrying these fluids. Administration of glucose, medication, nutrients, gases (oxygen), extraction of blood or ...
Good Morning all,I have a 80+ y/o female, A&0x3, s/p knee replacement (infected), get a PICC about about three weeks ago. Re-admitted for SOB. CT showed a PE. Doppler of lower extemities was clean, doppler of basilic showed a DVT without ettensnion (at PICC site). Pt is non-symptomatic. no swelling, no tenderness, no redness. If not for the PE and later diagnostics, wed have no clue she had the DVT. Her INR is therapeutic, shes ready to go home for three more weeks of IV ABX. Now my question: Do I move the PICC over to the other arm? Or since she is not symptomatic and we are keeping her INR therapeutic, do I leave the PICC where it is? With all the info at AVA about thrombus rates, my initial thought is to leave it be, and have family and clinic monitor. I suggested doppler studies at two week intervals but radiology shot me down, saying there was no data to support that practice.
My first PICC line was somewhere around 1999 or 2000. Im guessing around then because I dont ever remember having them in high school which I graduated from in 1998. I started receiving PICC lines for the same reason most of you start getting PICC lines; my peripheral lines would start to blow anywhere between 1-3 days. With 2 week stays, that meant that there were times I went through MULTIPLE I.V.s. As you can guess, that got old really fast. The other thing that was happening was because of my sensitive veins, they were having to pump the meds into me at an incredibly slow rate. Not that this was so much a problem medically, but mentally it was a little taxing being hooked up to my leash 24 hours a day. When Im in the Hole, I NEED to be active. If Im tethered to my I.V. pole that gets a little tough. So the decision was made for me to try a PICC line.. ...

This is a lengthy process that usually requires leaving your dog or cat at the vets office. The actual cleaning process lasts anywhere from 45 minutes to an hour and a half, depending on the condition of your pets mouth, and any specific dental work such as extractions that may need to be done. The good news is, your furry friend should get to come home the same day. Here, Dr. Tyler Pilkington, co-owner of Animal Clinic, Inc., explains the entire cleaning procedure:. A thorough physical exam, including examination of the teeth and oral cavity, precedes any procedure or recommendation, and routine bloodwork is often recommended prior to anesthesia. Following the exam, an intravenous catheter is placed to administer fluids before, during, and shortly after anesthesia. These support heart and kidney function. Next, a balanced injectable pain medicine is administered, and an "induction agent" that helps put your pet to sleep is given through the IV catheter. A tube is placed in the airway to ...

Food Training and Testing. Approximately 1 week after preparation with intravenous catheters, rats were food-restricted (5 g/day) for 48 h before starting food training. After the initiation of food training, animals received 12 g rat chow per day, at least 1 h after the end of the food training session. During the initial 30-min session, the animals received 45-mg food pellets at fixed intervals (one pellet every 12 s for 5 min and then a 5-min break; this sequence was repeated until a total number of 75 pellets was delivered), with no requirement to lever press. After this session and on subsequent days, rats were allowed to press a lever to receive the food pellets on a fixed ratio 1 time-out 1 s (FR1TO1 s) schedule of reinforcement. Only one lever was extended into the operant testing chamber during the initial food training period. The schedule was gradually changed according to the sequence FR1TO1 s, FR2TO10 s, and FR5TO20 s, with sessions lasting 30 min. Animals moved through the sequence ...

Her x-rays looked better...yay us. I could still see abnormal spots on there but who am I kidding, I am not a radiologist so it is not like I actually know what I am looking at. We had a nice little surprise with that Xray. Her picc line ended up in her neck some how. Then I had some back up Sunday doctor who was probably an intern come in and talk to me and he caused a major melt down with me that was not even needed. He told me all of her meds are getting in fine but they have to pull this picc and put in a new one. I said well if it is working why would you put her through all of that again? He said well she can develop a clot there that will go to the heart or brain. I said ok when will we do it. He said I dont know I have to call the picc team and she has to not eat for six hours. At this point I am thinking great my daughters life could be in danger and he does not know and how long has it been like this anyway, she has had the Picc since Tuesday.

I luckily was awake! I was sitting in bed at 2 A.M. frustrated I could not sleep. When all the sudden I was in a big pile of my own blood (and lipids)! I knew automatically it was from my Picc line and I assessed the situation. I have a tube called a Y-site that looks like a letter Y. This is so I can hook up to lipids and TPN at the same time. (so 2 separate bags, and 2 separate tubes connect to the Y-site and that connects to my Picc line.) Well, my lipids came off the Y-site and where pumping all over my bed. But that is not the worst part in the few minutes I had been sitting there my blood was pumping out of my Picc line and let me telling you it was flying out! That is the scary part, I worry if I would of been asleep would I have bled to death? Maybe my insomnia is a blessing!! I definitely want my J/G tubes now! (by now I mean yesterday) Back to the story... I was bleeding all over and lipids were pumping all over. I hurriedly grabbed a washcloth and covered up the y site which made me ...

Comparison of three types of central venous catheters in patients with malignant tumor receiving chemotherapy Shirong Fang,1 Jinhong Yang,2 Lei Song,3 Yan Jiang,1 Yuxiu Liu4 1Department of Anesthesiology, 2Department of Oncology, Weifang People’s Hospital, Weifang, 3Intensive Care Unit, The Affiliated Hospital of Qingdao University, Qingdao, 4Nursing College, Weifang Medical University, Weifang, People’s Republic of China Background: Central venous catheters (CVCs) have been an effective access for chemotherapy instead of peripherally intravenous catheters. There were limited studies on the choices and effects of different types of CVCs for chemotherapy. The aim of this study was to compare the complications, cost, and patients’ quality of life and satisfaction of three commonly used CVCs for chemotherapy, such as implanted venous port, peripherally inserted central catheters (PICCs), and external non-tunneled central venous catheters (NTCs).Methods: A double-center prospective
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
Recently, various NIR devices have been launched to support intravenous cannulation. Although it is generally believed that visualization of veins with NIR might aid intravenous cannulation, thus far only 1 NIR device (the VeinViewer; Christie Medical Innovations, Memphis, TN) has been evaluated systematically.16-18 In the current study, we evaluated the clinical use of another such device at the operating rooms of a tertiary pediatric referral university hospital. The VascuLuminator was able to visualize the veins in more than 80% of the patients and was rated helpful by the performer in 21.6% of the cases. Nevertheless, the use of the device did not result in a significant improvement in success at first attempt or time to successful cannulation. Even when the NIR vascular imaging system was considered helpful, the rate of success at first attempt was not significantly higher.. In interpreting our findings, several aspects have to be taken into account. First, we chose a pragmatic, cluster ...
A severely calcified ascending aorta and arch are considered to increase the risk of a cerebral emboli occurring in patients undergoing aortic valve replacement. Several technical options have been used to avoid this complication, such as deep hypothermic circulatory arrest with or without ascending aortic replacement, endarterectomy of the ascending aorta, aortic inspection and cross-clamping during hypothermic circulatory arrest, and multiple arterial cannulation using the EndoClamp aortic balloon catheter [2-5]. In the present case undergoing aortic valve replacement, we selected bilateral axillary artery cannulation and short-term moderate hypothermic circulatory arrest for cross-clamping of the porcelain aorta to prevent neurological complications. We did not perform aortic replacement because the aortic arch and descending aorta were also severely calcified.. De Paulis et al. previously reported the usefulness of double-arterial cannulation for aortic valve replacement in three patients ...
Performing Intravenous Cannulation. Health workers use different methods of cannulation depending on their individual preferences. But to find a method with which you are most comfortable with is the real thing.. Before touching the cannula, make sure that you follow certain steps to ensure complete hygiene. Do wash and sterilize your hands. Also, it would be better if the patient is politely informed that cannulation process is required. You are supposed to explain entire process to the subject, but just saying, "Itll be a little uncomfortable, but dont worry, therell be hardly any pain", will do fine too. Also, you should ensure taking consent from the subject before proceeding with cannulation.. Ready Equipments. You need to ensure all required equipments are in place and readily accessible. Gather non sterile globes, apron, cannula, cannula dressing, saline and syringe (10ml), gauze, alcohol swab, and tourniquet.. Find Right Vein, Right Spot. Before puncturing, you need to make sure that ...
Two 18-G peripheral intravenous catheters and a 20-G right radial arterial catheter were placed, and standard ASA monitoring was performed in the angiography suite. Further invasive monitoring was not necessary because of the stability of the patients chest pain with nitroglycerin patch, normal electrocardiography results, no history of congestive heart failure or arrhythmia, and the relatively hemodynamic stability of the TIPS procedure. Sedation was achieved with 50 micro gram *symbol* kg sup -1 *symbol* min sup -1 propofol, 2 mg midazolam in 0.5-mg increments, and 100 micro gram fentanyl in 25-micro gram boluses intravenously. Two hours after the start of the procedure, the patients systolic blood pressure decreased from 110 to 60 mmHg with an increase in heart rate to 110 beats/min. No ST-T changes were noted on electrocardiogram monitoring. This coincided with dilation of the Wallstent device. As the patient lost consciousness, ventilation was supported with 100% Oxygen2via mask followed ...
Two methods are described here using the radial artery, the most common site because of low complication rates. Methods can be adapted to other arteries. Another common site is the posterior tibial artery, as both the radial and posterior tibial arteries have good collateral circulation. Ulnar (to be used only in the absence of previous radial artery puncture attempt) and dorsalis pedis arteries are alternative sites. The temporal, brachial, and femoral arteries are not recommended. Axillary artery cannulation is very difficult and also not recommended. Temporal artery catheterization may have adverse neurologic sequelae. The brachial artery does not have good collateral flow and can have a lot of complications. Lateral or posterior wrist transillumination or Doppler/real-time ultrasound may be helpful in locating the artery in premature infants. Arterial catheterization requires patience ...
A stabilizing fitting for securely holding an intravenous catheter to a patients skin at a venipuncture site comprises a laminar base member with an adhesive lower surface and a catheter hub retaining cradle on its upper surface. After insertion of the catheter into a vein and connection to an infusion tube, the catheter hub is pressed into the cradle which locates the hub laterally and longitudinally and the fitting is dabbed onto the patients skin. Stabilization is then achieved by affixing criss-cross adhesive tapes over the assembly.
Vapocoolant sprays have been used to decrease the pain associated with painful medical procedures such as immunizations, needle aspirations, injections, venipuncture and intravenous cannulation. In general, vapocoolant sprays , have been found to be effective in decreasing the pain of various medical procedures. Moreover, the use of vapocoolant sprays ,unlike other local anesthetics , such as infiltrative lidocaine , is not associated with a painful injection and does affect the success rate of the procedure including intravenous cannulation and may even increase the success rate of the intravenous cannulation ...
Background Septic shock is associated with high mortality. Aged and multimorbid patients are not always eligible for intensive care units. Norepinephrine is an accepted treatment for hypotension in septic shock. It is unknown whether norepinephrine has a place in treatment outside an intensive care unit and when given peripherally. Objectives To describe mortality, Acute Physiology And Chronic Health Evaluation (APACHE-II), time to mean arterial pressure |65 mmHg, and adverse events in patients with septic shock receiving norepinephrine peripherally in an intermediate care unit. Methods From a retrospective chart review of 91 patients with septic shock treated with norepinephrine for hypotension, ward mortality, 30-, 60- and 90-day mortality, standardized mortality ratio (SMR) and adverse events (necrosis and arrhythmia) were analysed. Administration route via peripheral venous catheter or central venous catheter was registered. Results Median age was 81 (43-96) years and median APACHE-II score

Venous cannulation is a common procedure with a relatively high first time failure rate-one that would be unacceptable in other invasive procedures. Most practitioners could relate at least a few "horror" stories of patients with difficult access, and no doubt, more than a few patients view cannulation with some trepidation. When troubleshooting difficult peripheral intravenous access, the use of warmth in various forms is frequently recommended. Lenhardt et al, in 2 studies, offer the first evidence of the superiority of this practice over standard insertion.. The designs of the studies were good. Randomisation was secure with an audit confirming the integrity of the allocation sequence. Loss to follow up was minimal. Efforts were made to blind the nurse anaesthetist and residents to group assignment; however, complete blinding was impossible due to the obvious change in hand temperature. Although some subjectivity exists in the method used to determine vein scores, outcomes such as time to ...
On Friday I had to go back into hospital as they had arranged for me to have my picc line fitted as they had a cancellation. The tablets I was supplied with on the Thursday I was told not to take as they would probably start the treatment earlier now. I was going to have the picc line fited on Monday and they had given me some Dexamethasone and a few other tablets to get me started while I waited and then start the treatment on the Thursday. Now that has all changed.. Friday I first thing I had a cannula fitted to my right wrist. They put it there as so that they could fit the picc line to my left arm and if they couldnt get it in they could still use my right arm. With the cannula fitted I had to wait for some platelets to arrive, which they gave to me through the cannula afterwards they gave me a unit of blood. Not long after starting the blood the Nurse found out I was having my picc line fitted at about one (which in hospital time means anywhere between one and a couple of hours). She ...

On the day the surgery is elected, your pet will be admitted in the morning, typically fasted for 8-10 hours with certain exceptions. Your pet will be medicated with slight sedation prior to anesthesia to alleviate pain and anxiety. Intravenous access in the form of an IV catheter will be placed for administration of medication, fluids, and other use, should immediate intravenous access be needed. The surgery will be performed in the morning and you will be notified once your pet is in recovery. Generally, your pet will stay one night in the hospital following surgery to ensure there are no lingering effects of the medication used during anesthesia, or any immediate complications associated with the surgery prior to being discharged.. Following surgery, a follow up exam is generally recommended in 10-14 days to assure adequate wound healing in the small incision in the groin area and suture removal. Generally, any medication for congestive heart failure may be discontinued at this time. Repeat ...
To the Editor:. We read with interest the article by Reggia, et al1, a monocentric study analyzing the efficacy and safety of switching from intravenous (IV) to subcutaneous (SC) formulation of abatacept (ABA) in patients with rheumatoid arthritis. The authors report a relatively high risk of disease relapse (27%) occurring in a mean of 11 weeks after switching to SC administration. The study did not find any significant predictive factor for a switch failure. The concern that patients with a higher body mass index could receive lower cumulative doses compared to weight-tiered monthly infusions, leading to a significant influence on treatment efficacy, was not confirmed by this study, or by previous dose-finding trials and non-inferiority randomized studies2,3,4.. We describe our experience based on a case series of 21 consecutive patients switching from ABA IV to SC administration at our center. The switch was motivated by difficulties in obtaining peripheral venous access, or to optimize ...
Hi Jan:. As you know from previous posts I have a PICC line that I use just for hydration purposes.(one liter a day). I have had 3 lines over the past 9 months. Its easier to put in a replacement PICC line than the original line. Prior to this I was getting an angiocath each week in order to get the fluids. My arms got totally scarred up and are still healing from all the "sticks". Prior to the angiocaths I was in the ER every other week with severe dehydration. My thinking was to treat the symptoms, dehydration, and then try and treat the cause. I have felt much, much better since I have been adequately hydrated. I have returned to work, I have travelled to the islands and I have felt much stronger overall. I know the PICC line is not a permanent solution but I believe it is buying me time to try and find the ultimate answer. It sure beats feeling terrible and going to the ER. I have other issues than most, I have had 2/3 of my pancreas removed, etc. and I have never suffered from UC or ...

When I was a paramedic student, my instructor took great pains to show us how to tear thin little strips of adhesive tape to secure IV catheters and endotracheal tubes. We fashioned elegant little chevrons of tape over the wings on our IV catheter hubs (seriously, they had wings) to secure them without obscuring the cannulation site. And we used to tear a one-inch strip of tape longitudinally for a few inches, wrapping one strip around the endotracheal tube and the other across the face like a big mustache. ...

Indwelling arterial catheters are used routinely for continuous haemodynamic monitoring and obtaining repetitive blood samples. The radial artery is the most common site for cannulation. We report a case of forearm ischaemia after radial artery cannulation, which probably went unnoticed for several hours. The ischaemia resulted in an upper arm amputation. The use of a 22 gauge cannula and the use of ultrasound for cannulation may reduce the risk of this complication. We also emphasise the importance of good physical monitoring of patients who are under our care in the intensive care unit.. ...

An electro-stimulation device includes a pair of electrodes for connection to at least one location in the body that affects or regulates the heartbeat. The electro-stimulation device both electrically arrests the heartbeat and stimulates the heartbeat. A pair of electrodes are provided for connection to at least one location in the body that affects or regulates the heartbeat. The pair of electrodes may be connected to an intravenous catheter for transvenous stimulation of the appropriate nerve. A first switch is connected between a power supply and the electrodes for selectively supplying current from the power supply to the electrodes to augment any natural stimuli to the heart and thereby stop the heart from beating. A second switch is connected between the power supply and the electrodes for selectively supplying current from the power supply to the electrodes to provide an artificial stimulus to initiate heartbeating. In another aspect, the invention is directed to a method for arresting the beat

Biofilms are bacterial colonies that are attached to a surface. They grow from suspended, or planktonic, cells attaching to the surface and by cell division and movement of existing attached cells. Biofilms are found naturally in many places, including teeth (plaque), medical devices such as intravenous catheters, prosthetic heart valves, and cardiac pacemakers, in sewage pipelines, ship hulls, and many other non-human environments. Such colonies display complex spatial and temporal development patterns that are the result of both cell-cell interactions and cell-environment interactions. ...

Today started early with a call from our nurse practitioner Kim, who is very kind and caring. She called around 5 AM letting us know that Haley has an infection from her PICC line. Haley still had the PICC line for the TPN that she is still getting. Haleys PICC line was infected with yeast, the very same thing that our precious little Ashlyn initially got infected with. The good thing about it is that because of two wonderful and observant nurses Brandi, and Kodi it seems it has been caught early enough to treat, unlike Ashlyn. We are so grateful to Brandi and Kodi for being the kind of nurses they are. They are extremely good with our girls, and they are very good at what they do. They are not 100% sure yet if it is yeast, they will have a microbiologist look at it in the morning. They seem pretty confident that it is though. We just returned home from the NICU and Haley seemed just fine. They have put her on an anti-fungal medication called amphotericin. It is a terrible drug for the kidneys, ...

Transfuse enough, but no more. The goal is a well-perfused patient. Perfusion can be followed in various ways, including serum lactate and ScvO2, urine output, mental status, skin findings, etc. Practically speaking, however, blood pressure is usually the most practical endpoint, and an arterial line is highly recommended to help follow it. Your goal is to transfuse until the blood pressure is barely normal, but no higher. Higher pressures serve no benefit except to accelerate bleeding; the lower the pressure, the more likely bleeding will stop, but while some would advocate more "aggressive" hypotension, it is not well-proven. Therefore, the familiar MAP goal of 65 is probably reasonable. When the MAP dips, give balanced blood; when you reach 65, stop. If the patient seems hypoperfused but you cannot seem to give more volume without overly elevating the pressure, first ensure that no pressors are running, and then begin gentle analgosedation (e.g. small boluses of fentanyl). While no sedation ...

Internal jugular vein cannulation has become a routinary and clinically important aspect of medical care in critically ill patients. The landmark-guided technique usually affords rapid and easy vascular access, but it is not always successful and may be complicated by arterial puncture, hematoma, pneumothorax. A prospective, descriptive study is reported on the use and success of ultrasound-assisted central vein catheterization in dialysis patients who had an indication for internal jugular vein catheterization. Data were collected prospectively on number of punctures, needle passes, and success rates. Over a 6-year period, there were 220 attempts at internal jugular catheterization in 205 patients and ultrasound guidance was used in 210 of the 220 (95%) attempts. Incidences of successful puncture and cannulation using ultrasound were 100% (210 out of 210) and 99.5% (209 out of 210), respectively, compared with 80% (8 out of 10) and 80% (8 out of 10) in the landmark group.

AU - Agarwal, Shvetank. AU - Rotem, Eran. PY - 2018/7/1. Y1 - 2018/7/1. N2 - Catheter-directed thrombolysis (CDT) for the treatment of acute pulmonary embolism (PE) has gained popularity in recent years, but potential complications during the procedure and their management are not frequently discussed in the literature. In this case report, we describe the clinical dilemma regarding the postoperative anticoagulation management of a 60-year-old male who developed cardiac perforation during a CDT of an acute saddle PE. Early resumption of systemic heparin in such cases may help in clot resolution; however, it can worsen the hemopericardium. On the other hand, delaying restarting heparin may help in healing of the cardiac perforation but can lead to clot propagation. As the chest tube output was minimal initially, ...

Peripheral nerve blocks are effective in treating acute pain, thereby minimizing the requirement for opiate analgesics. Fractured neck of femur (FNF) is a common, painful injury. The provision of effective analgesia to this cohort is challenging but an important determinant of their functional outcome. We investigated the analgesic efficacy of continuous femoral nerve block (CFNB) in patients with FNF. Following institutional ethical approval and with informed consent, patients awaiting FNF surgery were randomly allocated to receive either standard opiate-based analgesia (Group 1) or a femoral perineural catheter (Group 2). Patients in Group 1 received parenteral morphine as required. Those in Group 2 received a CFNB comprising a bolus of local anaesthetic followed by a continuous infusion of 0.25% bupivacaine. For both Groups, rescue analgesia consisted of intramuscular morphine as required and all patients received paracetamol regularly. Pain was assessed using a visual analogue scale at rest and

In human anatomy, the cephalic vein is a superficial vein in the arm. It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle. Near the shoulder, the cephalic vein passes between the deltoid and pectoralis major muscles (deltopectoral groove) and through the deltopectoral triangle, where it empties into the axillary vein. The cephalic vein is often visible through the skin, and its location in the deltopectoral groove is fairly consistent, making this site a good candidate for venous access. Permanent pacemaker leads are often placed in the cephalic vein in the deltopectoral groove. The vein may be used for intravenous access, as large bore cannula may be easily placed. However, the cannulation of a vein as close to the radial nerve as the cephalic vein can sometimes lead to nerve damage. Ordinarily the term cephalic refers to anatomy of the head. When Persian physician ...
