    Central venous catheters are of an essential importance to critically ill patients who require long-term venous access for various purposes. Their use made the treatment much easier, but still they are not harmless and are prone to numerous complications. Catheter infections represent the most significant complication in their use. The frequency of infections varies in different patient care settings, but their appearance mostly depends on the patient's health condition, catheter insertion time, localization of the catheter and type of the used catheter. Since they are one of the leading causes of nosocomial infections and related to significant number of morbidity and mortality in intensive care units, it is very important that maximal aseptic precautions are taken during the insertion and the maintenance period. Prevention of infection of the central venous catheters demands several measures that should be applied routinely.

    Full Text Available We report an uncommon complication of subclavian central venous catheterization, discovered at thoracotomy. The central venous catheter (CVC was placed by left infraclavicular route after induction of general anesthesia. CVC was secured after aspiration of blood and satisfactory central venous tracing. On thoracotomy, CVC was noticed to traverse the pleural cavity while the tracing was normal. CVC was thus removed consequent to which bleeding from each puncture site was noticed, that were secured surgically.

    Central venous access is increasingly becoming the domain of the radiologist, both in terms of the insertion of central venous catheters (CVCs) and in the subsequent management of these lines. This article seeks to provide an overview of the CVC types available for paediatric patients and a more detailed explanation of the spectrum of complications that may lead to catheter malfunction. A standard catheter contrast study or 'linogram' technique is described. The normal appearances of such a study and a detailed pictorial review of abnormal catheter studies are provided, together with a brief overview of how information from catheter investigations can guide the management of catheter complications.

    Primary misplaced or secondary flipped implanted catheters are located mostly in the right jugular vein. We demonstrate an effective method to replace fix implanted catheters such as Ports, Grochomg or Hickman catheters. Using a femoral venous approach, replacement into the superior vena cava can easily be done with a Sidewinder 1 catheter which is hooked over the misplaced central venous approach. In all our patients the method was successful. The repositioning technique described is simple, fast and has low costs. We can keep sterile conditions and do not need to solve the catheters' fixation. (orig.)

    Peripherally inserted central catheters (PICC) are widely used to provide central venous access, often in chronically ill patients with long-term intravenous access requirements. There are a number of significant complications related to both insertion and maintenance of PICC lines, including catheter malposition, migration, venous thrombosis, and line fracture. The incidence of these complications is likely to rise as the number of patients undergoing intravenous outpatient therapy increases, with a corresponding rise in radiologist input. This paper provides an overview of the relevant peripheral and central venous anatomy, including anatomical variations, and outlines the complications of PICC lines. Imaging examples demonstrate the range of radiological findings seen in these complications.

    We evaluated the technical success and complication rates associated with the radiological placement of tunneled central venous catheters in pediatric patients. Between May 1, 2005 and March 31, 2008, a total of 46 tunneled central venous catheters were placed in 34 children (M:F = 22:12; mean age, 9.9 years [9 months to 16.8 years]). All procedures were performed under ultrasonographic and fluoroscopic guidance. Follow-up data were obtained through the retrospective review of the medical records. We used the Kaplan-Meier survival method for the evaluation of survival rate of the catheters. All procedures were technically successful. The observed periprocedural complications included hematoma formation in three patients. The mean catheter life was 189.3 days (total, 8710 days; range, 7-810). Catheters were removed due to death (n=9), the end of treatment (n=8), catheter sepsis (n=4), malfunction (n=8), and accidental removal (n=4). The rate of catheter sepsis and malfunction was 0.459 and 0.919 for every 1000 catheter days, respectively. The expected mean catheter life was 479.6 days as per the Kaplan- Meier analysis. The results suggest that the radiologic placement of a tunneled central venous catheter is an effective technique with a high technical success rate and low complication rate.

    Central venous catheters (CVCs) are commonly used in children, and inadvertent arterial or extravascular cannulation is rare but has potentially serious complications. To identify the radiographic signs of arterial placement of CVCs. We retrospectively reviewed seven cases of arterially malpositioned CVCs on chest radiograph. These cases were identified through departmental quality-assurance mechanisms and external consultation. Comparison of arterial cases was made with 127 age-matched chest radiographs with CVCs in normal, expected venous location. On each anteroposterior (AP) radiograph we measured the distance of the catheter tip from the right lateral border of the thoracic spine, and the angle of the vertical portion of the catheter relative to the midline. On each lateral radiograph we measured the angle of the vertical portion of each catheter relative to the anterior border of the thoracic spine. When bilateral subclavian catheters were present, the catheter tips were described as crossed, overlapping or uncrossed. On AP radiographs, arterially placed CVCs were more curved to the left, with catheter tip positions located farther to the left of midline than normal venous CVCs. When bilateral, properly placed venous catheters were present, all catheters crossed at the level of the superior vena cava (SVC). When one of the bilateral catheters was in arterial position, neither of the catheters crossed or the inter-catheter crossover distance was exaggerated. On lateral radiographs, there was a marked anterior angulation of the vertical portion of the catheter (mean angle 37 ± 15 standard deviation [SD] in arterial catheters versus 5.9 ± 8.3 SD in normally placed venous catheters). Useful radiographic signs suggestive of unintentional arterial misplacement of vascular catheters include leftward curvature of the vertical portion of the catheter, left-side catheter tip position, lack of catheter crossover on the frontal radiograph, as well as exaggerated

    Central venous catheters (CVCs) provide valuable vascular access. Complications associated with the insertion and maintenance of CVCs includes pneumothorax, arterial puncture, arrhythmias, line fracture, malposition, migration, infection, thrombosis, and fibrin sheath formation. Image-guided CVC placement is now standard practice and reduces the risk of complications compared to the blind landmark insertion technique. This review demonstrates the imaging of a range of complications associated with CVCs and discusses their management with catheter salvage techniques

    Thirty-nine hemodialysis patients with permanent central venous catheters were analyzed for bacterial catheter colonization comparing different catheter-lock strategies. The closed needleless Tego connector with sodium chloride lock solution was significantly more frequently colonized with bacteria than the standard catheter caps with antimicrobially active citrate lock solution (odds ratio, 0.22 [95% confidence interval, 0.07-0.71]; P = .011).

    Full Text Available Background/Aim. Central venous catheters (CVC are at the crucial importance, particulary in the intensive therapy units. In order to handle a CVC safely, nursing students need to acquire theoretical and practical knowledge during the course of their studies. The aim of the study was to establish theoretical knowledge of nursing students about the procedures of nurses in placing and removing a central venous catheter (CVC, dressing the catheter entry point, the reasons for measuring central venous pressure (CVP, possible complications and risk factors for developing infections related to CVC. Methods. The questionnaire developed specifically for this cross-sectionl study was handed out to 87 full-time students and 57 part-time students. Results. The results show that all the surveyed nursing students know why chest radiography is carried out when inserting a catheter, have relatively good knowledge of CVC insertion points, procedures carried out in case of a suspected catheter sepsis and complications and risk factors for the development of infections related to CVC. However, the study show that the majority of students have insufficient knowledge of the procedures accompanying insertion of a catheter, signs that indicate correct functioning of CVC, frequency of flushing a catheter when it is not in use and the reasons for introducing an implanted CVC. Conclusion. Based on the results of the study it can be concluded that the second-year nursing students have insufficient knowledge of CVC. In order to correctly and safely handle a CVC, good theoretical knowledge and relevant practical experience are needed. The authors therefore believe that, in future, the classes should be organized in smaller groups with step-by-step demonstrations of individual procedures in handling a CVC, and the students encouraged to learn as actively as possible.

    Indwelling central venous catheters have been reported to increase the risk of superior venous cava (SVC) syndrome. This case report describes the development of acute SVC syndrome in a 28-year-old woman with end-stage renal disease implanted with a left-side hemodialysis reliable outflow graft and a right-side double lumen hemodialysis catheter via internal jugular veins. Her symptoms were not alleviated after catheter removal and systemic anticoagulation therapy. She was eventually treated with catheter-directed thrombolysis and a predischarge computer tomographic venogram on postthrombolytic procedure day 7 showed patent central veins and patient remained asymptomatic. This case demonstrates that catheter-directed thrombolysis can be safely employed to treat refractory catheter-induced acute SVC syndrome in end-stage renal disease patients.

    We aimed to compare the effectiveness of various catheters for prevention of catheter-related infection and to evaluate whether specific catheters are superior to others for reducing catheter-related infections. We identified randomised, controlled trials that compared different types of central venous catheter (CVC), evaluating catheter-related infections in a systematic search of articles published from January 1996 to November 2009 via Medline, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials. Network meta-analysis with a mixed treatment comparison method using Bayesian Markov Chain Monte Carlo simulation was used to combine direct within-trial, between-treatment comparisons with indirect trial evidence. Forty-eight clinical trials (12 828 CVCs) investigating 10 intervention catheters contributed to the analyses. For prevention of CVC colonisation, adjusted silver iontophoretic catheters (odds ratio: 0.58; 95% confidence interval: 0.33-0.95), chlorhexidine and silver sulfadiazine catheters (0.49; 0.36-0.64), chlorhexidine and silver sulfadiazine blue plus catheters (0.37; 0.17-0.69), minocycline-rifampicin catheters (0.28; 0.17-0.43) and miconazole-rifampicin catheters (0.11; 0.02-0.33) were associated with a significantly lower rate of catheter colonisation compared with standard catheters. For prevention of CRBSI, adjusted heparin-bonded catheters (0.20; 0.06-0.44) and minocycline-rifampicin catheters (0.18; 0.08-0.34) were associated with a significantly lower rate of CRBSI with standard catheters. Rifampicin-based impregnated catheters seem to be better for prevention of catheter-related infection compared with the other catheters.

  16. The Malposition of Central Venous Catheters in Children

    International Nuclear Information System (INIS)

    Contemporary medical care, especially in the field of pediatrics often requires central venous line (CVC – Central Venous Catheter) implantation for carrying out treatment. Some conditions are treated intravenously for several months, other require long-term venous access due to periodical administration of medications or daily nutritional supplementation. A total number of 309 CVCs were implanted at Children’s University Hospital in Cracow between January 2011 and December 2012 (24 months). Malposition of the CVC is not common. The target of our article was to present two rare cases of malposition of catheters and two displacements of catheter due to chest tumors, and to enhance the importance of differential diagnostic imaging when difficulties occur. CVC malposition was detected with different imaging modalities followed by appropriate medical procedures. In case of any difficulties with central lines, it is necessary to investigate the underlying cause. The central line team at hospital cooperating with other specialists is needed to detect complications and to prevent them

    Full Text Available Migration of the tip of central venous catheters is not an uncommon event and the mechanism for this is not clear. Increased intrathoracic pressure due to coughing, sneezing or weight lifting, changing the body position or physical movements such as abduction or adduction of the arms is thought to be the cause of such migration. We present here a case of a patient with a port catheter tip that migrated from the left subclavian to the superior vene cava following extubation.

    Large numbers of central venous catheters (CVCs) are placed each year and misplacement occurs frequently. This review outlines the normal and abnormal anatomy of the central veins in relation to the placement of CVCs. An understanding of normal and variant anatomy enables identification of congenital and acquired abnormalities. Embryological variations such as a persistent left-sided superior vena cava are often diagnosed incidentally only after placement of a CVC, which is seen to take an abnormal course on X-ray. Acquired abnormalities such as stenosis or thrombosis of the central veins can be problematic and can present as a failure to pass a guidewire or catheter or complications after such attempts. Catheters can also be misplaced outside veins in a patient with otherwise normal anatomy with potentially disastrous consequences. We discuss the possible management options for these patients including the various imaging techniques used to verify correct or incorrect catheter placement and the limitations of each. If the course of a misplaced catheter can be correctly identified as not lying within a vulnerable structure then it can be safely removed. If the misplaced catheter is lying within or traversing large and incompressible arteries or veins, it should not be removed before consideration of what is likely to happen when it is removed. Advice and further imaging should be sought, typically in conjunction with interventional radiology or vascular surgery. With regard to misplaced CVCs, in the short term, a useful aide memoir is: 'if in doubt, don't take it out'.

    This study comprises five different kind of venous central catheters, 103 in total, made of Polyurethane Tecoflex, Polyurethane Vialon, PTFE and PVC, and the influence of their raw material on the microbial colonization. Patients age and sex, besides their clinical conditions, were taken into account, and neither considered as a sample vicious, nor associated with colonization. When the tips of the catheters were asseptically inoculated in Tryptic Soy Broth and Tioglicolate, colonization was detected in 15.5% of the catheters. Coagulase negative Staphylococcus, some of which with biofilm, were the predominant organisms found, although some bacillus have also been detected: Enterobacter aerogenes, Hafnia alvei, Pseudomonas cepacia, Xanthomonas maltophilia and Aeromonas sobria. It was not possible to notice any association between the colonization of the catheters and their raw material, probably due to the influence of a previous contact and linking with blood components. This contact causes a thin coating on the surface of the cathether, which makes all the catheters similar in respect of the attachment of a bacterial cell. So, the colonization depends on the virulence of the organism, much more then on the nature of the catheter. PMID:10326311

    For modern medicine central venous catheters play an important role for diagnostic and therapeutic options. Catheter implantation, complication detection and therapy of catheter complications are an increasing demand for the radiologist. The review article provides an overview of different catheter types, their indications, advantages and disadvantages. Catheter malpositions are usually detectable in conventional X-ray. Most malpositions are correctable using interventional-radiological techniques. In addition therapeutical options for thrombotic complications (venous thrombosis, catheter occlusion, fibrin sheath) are discussed. In case of an infectious catheter complication, usually a catheter extraction and re-implantation is necessary.

  2. Heparin Leakage in Central Venous Catheters by Hemodynamic Transport

    2014-11-01

    Central venous catheters (CVCs), placed in the superior vena cava for hemodialysis, are routinely filled with heparin, an anticoagulant, while not in use to maintain patency and prevent thrombus formation at the catheter tip. However, the heparin-lock procedure places the patient at risk for systemic bleeding incidences, as heparin is known to leak into the blood stream. We propose that the driving mechanism behind heparin leakage is advective-diffusive transport due to the pulsatile blood flow surrounding the catheter tip. This novel hypothesis is based on Planar Laser Induced Fluorescence (PLIF) measurements of heparin transport from a CVC placed inside an in vitro pulsatile flow loop and validated with CFD simulations. The results show an initial, fast (catheter lumen, where concentration is still high, that is insufficient at replenishing the lost heparin at the tip. These results, which estimate leakage rates consistent with published in vivo data, predict that the concentration of heparin at the catheter tip is effectively zero for the majority of the interdialytic phase, rendering the heparin lock ineffective.

    Full Text Available Introduction/Aim. Intravascular device placement (IVD is a part of everyday medical practice, however, its application is associated with a high risk of onset of nosocomial infections (NI and increased mortality and morbidity. Nosocomial blood infections (NBIs account for 10% of all the registered NI. NBIs are more frequent in patients with a placed IVD and it present an important risk factor for the onset of NBI, i.e. catheter-associated NBIs (CANBIs. Pathogenesis of CANBIs is complex and conditioned by the presence of different characteristics related to a catheter, patient and a specific causative organism. The most common CRBSI causes include coagulase-negative staphylococcus, S. aureus, Enterobacter spp, Candida spp, Klebsiella spp, Pseudomonas spp. and Enterococcus spp. Methods. All the patients hospitalized at the Intensive Care Department of the Clinic of Digestive Diseases over the period January 1, 2004-September 1, 2004 were retrospectively analyzed. The study included 107 patients in whom central venous catheter (CVC was placed for more than 48 h. All the causes isolated from a CVC segment were recorded. Culture, isolation and identification of the causative organisms were performed using standard microbiological methods in the Bacteriological Laboratory within the Emergency Center, Clinical Center of Serbia. Catheter segment samples (tip of the CVC 3-5 cm long were analyzed. Based on the insight into medical documentation, patients’ examination and medical staff interview, catheter and patient-related characteristics were recorded. Results. A total of 107 CVCs were analyzed, out of which 56 (52% were sterile while 51 (48% were colonized. The results of our study evidenced that total parenteral nutrition (TPN (p < 0.05, number of catheterization days (p < 0.05, and central venous pressure measurement (p < 0.05 were significantly associated with CVC colonization.

    Central venous catheters (CVC) are used to provide vascular access during hemodialysis in patients with end-stage kidney disease. Despite several advantages and widespread use, CVCs have a high incidence rate of clot formation during the interdialytic phase (48 hrs). In an attempt the prevent clot formation, hospitals routinely administer heparin, an anticoagulant, into the catheter after a dialysis session. It has been reported, however, that up to 40% of the heparin solution will leak into the blood stream during the interdialytic phase, placing the patient at risk for systemic bleeding incidences. The aim of this study is to determine the role that advective-diffusive transport plays in the heparin leaking process. Numerical simulations of heparin convective mass transfer have been conducted, showing that while advective losses may be significant at the tip, previous studies may be overestimating the total amount of heparin leakage. To validate the quantitative prediction from the simulations, P.L.I.F. is used to experimentally measure heparin transport from CVCs placed in an idealized Superior Vena Cava with physically accurate pulsatile flow conditions. Improved understanding of flow near the catheter tip is applied to improve catheter design and heparin locking procedures.

    Central venous catheters are used for delivering medications and parenteral nutrition, measuring hemodynamic variations, and providing long-term intravenous access. In our clinic, during liver transection using a living-liver donor, peripherally inserted central venous catheters are generally preferred because they involve a less invasive technique with a lower risk of complications. In this report, we present the case of a 36-year-old male liver donor into whom we peripherally inserted a central venous catheter from his left basilic vein. After transecting the hepatic vein, the surgeon found foreign material inside the venous lumen, which turned out to be the distal segment of the catheter.

    The purpose of this retrospective study was to report 11 cases of severe vascular complications after central venous catheter misplacement. For each patient, data collection included body mass index, the diagnosis at admission, the site of the procedure, the type of catheter, coagulation parameters, the imaging modalities performed and the applied treatment. Eight patients had a lesion of the subclavian artery. Brachiocephalic vein perforations were assessed in three more patients. All patients had a chest roentgenogram after the procedure, six a CT examination, and four an angiographic procedure. Seven patients had a body mass index above 30, and 5 patients had coagulation disorders prior to the procedure. Seven patients were conservatively managed, 2 patients died despite resuscitation, 1 patient was treated with a stent graft, and one by superselective embolization. Subclavian or jugular vein temporary catheter positioning is a practical approach. Identification of any iatrogenic perforation of the subclavian artery or central veins urges obtainment a chest roentgenogram and, when required, a chest CT, selective angiograms or venograms. Body mass index superior to 30, previous unsuccessful catheterization attempts, and coagulation factor depletion seemed to account for risk factors. Recognition of clinical and radiological complications is mandatory. (orig.)

    Dual-lumen haemodiafiltration catheters enable continuous renal replacement therapy in the critically ill and are often co-located with central venous catheters used to infuse drugs. The extent to which infusions are immediately aspirated by an adjacent haemodiafiltration catheter remains unknown. A bench model was constructed to evaluate this effect. A central venous catheter and a haemodiafiltration catheter were inserted into a simulated central vein and flow generated using centrifugal pumps within the simulated vein and haemodiafiltration circuit. Ink was used as a visual tracer and creatinine solution as a quantifiable tracer. Tracers were completely aspirated by the haemodiafiltration catheter unless the infusion was at least 1 cm downstream to the arterial port. No tracer was aspirated from catheters infusing at least 2 cm downstream. Orientation of side ports did not affect tracer elimination. Co-location of central venous and haemodiafiltration catheters may lead to complete aspiration of infusions into the haemodiafilter with resultant drug under-dosing.

This protocol describes a way to grow Candida albicans biofilms on the interior lumen of central venous catheters surgically implanted into rats, which mimics quite well the clinical cases of biofilms found on human central venous catheters. These infected catheters can then be studied via a multitude of different experiments...

    Stenting of the central veins is well established for treating localized venous stenosis. The techniques regarding catheter preservation for central venous catheters in the superior vena cava have been described. We describe here a method for stent implantation in the superior vena cava and the left brachiocephalic vein, and principally via a single jugular venous puncture, while saving a left sided jugular central venous catheter in a patient suffering from central venous stenosis of the superior vena cava and the left brachiocephalic vein.

    Full Text Available Insertion of central venous catheter is an accepted method for hemodynamic monitor-ring, drug and fluid administration, intravenous access, hemodialysis and applying cardiac pace-maker in hospitalized patients. This procedure can be associated with severe complications. The aim of this article is to provide a practical approach to prevent catheter malposition in states that the guide wire will not pass freely.During central venous insertion in internal jugular vein using modified seldinger technique, when after venous insertion, the passage of the guide wire shows difficulties and don’t pass freely, insertion of an intravenous cannula over the wire and re-insertion of the wire can help to prevent malposition of the wire and the catheter. Use of an intravenous cannula over the guide, in situations that the guide wire cannot pass freely among the needle inserted in internal jugular vein, and re-insertion of the guide can probably prevent or reduce the tissue or vascular trauma and the associated complica-tions. This simple maneuver can be helpful in difficult cases especially in cardiac surgery patients who receive high dose heparin and it is necessary to avoid traumatize-tion of carotid artery.

    To evaluate prospectively the results of interventional radiologic placement of tunneled central venous catheters, and subsequent complications. Between April 1997 and April 1998, a total of 557 tunneled central venous catheters were percutaneously placed in 517 consecutive patients in an interventional radiology suite. The indications were chemotherapy in 533 cases, total parenteral nutrition in 23 and transfusion in one. Complications were evaluated prospectively by means of a chart review, chest radiography, central vein angiography and blood/catheter culture. The technical success rate for tunneled central venous catheter placement was 100% (557/557 cases). The duration of catheter placement ranged from 4 to 356 (mean, 112{+-}4.6) days; Hickman catheters were removed in 252 cases during follow-up. Early complications included 3 cases of pneumothorax(0.5%), 4 cases of local bleeding/hematoma(0.7%), 2 cases of primary malposition(0.4%), and 1 case of catheter leakage(0.2%). Late complications included 42 cases of catheter-related infection(7.5%), 40 cases of venous thrombosis (7.2%), 18 cases of migration (3.2%), 5 cases of catheter / pericatheter of occlusion(0.8%), and 1 case of pseudoaneurysm(0.2%). The infection rate and thrombosis rate per 1000 days were 1.57 and 1.50, respectively. The technical success rate of interventional radiologic placement of tunneled central venous catheters was high. In comparison to conventional surgical placement, it is a more reliable method and leads to fewer complications.

    Long-term or repeated venous access in chelonians is difficult to obtain and manage, but can be critically important for administration of medications and blood sampling in hospitalized patients. Jugular catheterization provides the most rapid and secure route for vascular access, but catheters can be difficult to place, and maintaining catheter patency may be challenging. Long multilumen polyurethane catheters provide flexibility and sampling access, and minimize difficulties, such as catheter displacement, that have been encountered with traditional over-the-needle catheters. We describe placement of 4 Fr. 13-cm polyurethane catheters in three chelonians with the use of a modified Seldinger technique. Venous access was obtained with the use of an over-the-needle catheter, which allowed placement of a 0.018-in.-diameter wire, over which the polyurethane catheter was placed. Indwelling time has ranged between 1 and 4 mo currently. All tortoises were sedated for this procedure. Polyurethane central catheters provide safe, long-term venous access that allows clinicians to perform serial blood sampling as well as intravenous administration of medications, anesthetic agents, and fluids. A jugular catheter can also allow central venous pressure measurement. Utilization of central line catheters was associated with improvements in diagnostic efficiency and therapeutic case management, with minimal risks and complications.

    Central venous catheters (CVCs) are associated with occlusive, infectious, and thrombotic complications. The aim of this study was to determine if internal CVC tip position was correlated with subsequent complications. This was an institutional review board approved single-center retrospective review of 169 consecutive patients who underwent placement of 203 semipermanent CVCs. Using post-placement chest X-rays, a de novo scale of internal catheter tip position was developed. Major complications were recorded. A logistic regression analysis was used to determine if catheter tip position predicted subsequent complications. There were 78 men and 91 women with a mean age of 48 ± 11 years. There were 21 catheter tips placed in the subclavian/innominate veins, 32 in the upper superior vena cava, 113 in the atriocaval junction, and 37 in the right atrium. There were 83 complications occurring in 61 (36.1 %) patients, including sepsis in 40 (23.7 %), venous thrombosis in 18 (10.7 %), catheter occlusion in 16 (9.5 %), internal catheter repositioning in 6 (3.6 %), pneumothorax in 2 (1.2 %), and death in 1 (0.6 %). An internal catheter tip position peripheral to the atriocaval junction resulted in a catheter that was more likely to undergo internal repositioning (p venous thrombosis (p catheters were more likely to develop sepsis (45 %) than patients whose catheters were inserted through the upper extremity veins (18 %) (p catheter-associated morbidity and potentially mortality, the internal catheter tip should be positioned at the atriocaval junction or within the right atrium and femoral insertion sites should be avoided whenever possible.

    One hundred and seven Hickman catheters for haemodialysis were inserted in 90 end-stage chronic renal failure patients, and were used for 1-448 days (median 45 days). Sixty-nine per cent of the patients were treated without any problem for 1-165 days (median 34 days). Clinically evident complications occurred in 44 catheters inserted in 28 patients, and included outflow obstruction (16.8% of the catheters) and thrombosis (13.1% of the catheters). However, many episodes of clotting or insufficient flow could be corrected by simple manoeuvres. Other less frequent complications were recorded: sepsis, mainly in patients with increased risk factors (4.1% of the catheters), laceration of the catheter (3.7%) and occasional cases of jugular-vein phlebitis, transient palsy of a vocal cord, haematoma of the wound, and bleeding of the cutaneous orifice. No clinical sign of subclavian or innominate-vein thrombosis was observed. Nevertheless, a prospective study conducted in 50 asymptomatic patients demonstrated a 12% rate of anomalies of the venous system, although two-thirds of these alterations were mild and had no consequence. When the present series is compared to the results obtained with currently available percutaneous haemodialysis catheters, it is concluded that the Hickman catheter is a safe, comfortable and efficient vascular access device.

    The use of indwelling central venous catheters is essential for pediatric patients who require hemodialysis, parenteral nutrition, chemotherapy, or other medications. Fever is a common chief complaint in the emergency department, and fever in a patient with a central venous catheter may be related to a common cause of fever, or it may be due to a catheter-associated bloodstream infection. Catheter-associated bloodstream infections may also lead to additional complications such as sepsis, septic shock, or septic complications including suppurative thrombophlebitis, endocarditis, osteomyelitis, septic emboli, and abscesses. Early resuscitation as well as timely and appropriate antibiotic therapy have been shown to improve outcomes. This issue focuses on the approach to fever in pediatric patients with central venous catheters and the management and disposition of patients with possible catheter-associated bloodstream infections.

    Full Text Available INTRODUCTION Central venous catheters (CVC are used in the treatment of critically ill patients. Indications for placement of CVCs include hemodynamic monitoring, administration of intravenous fluids, medications and total parenteral nutrition. MATERIAL AND METHODS We investigated risk factors and effects of glycopeptide antibiotics on the development of central venous catheter-related infections in 300 patients treated in intensive care units. A semiquntitative culture technique was used. The investigation included: age, diagnosis on admission, catheter insertion site, catheter duration, the first or next catheter and using of glycopeptide drugs. RESULTS 91 catheters (30.3% were colonised, catheter-related infection was found in 50 catheters (16.7%. Infections were more frequent in catheters inserted through the internal jugular vein than in subclavian venous catheters; they were also more frequent if duration of catheterization was longer than seven days, but less frequent in patients who received glycopeptide antibiotics. The isolated microorganism was Staphylococcus aureus. DISCUSSION According to the literature, a number of catheter-related risk factors for infections include: insertion site, type of catheter, the number of manipulations, inadequat asepsis, lumen number, type of antiseptic. The relative importance of one risk factor over another is difficult to assess, given that studies have no priority report. CONCLUSION The duration of catheterization and the insertion site were the most frequent risk factors for infection. The use of glycopeptide antibiotics during catheterization has protective effects.

    BACKGROUND: Tunneled central venous catheters (CVCs) are inevitable in children with acute lymphoid leukemia (ALL). The aim of this study was to evaluate the risk of CVC-related complications in children with ALL in relation to timing of catheter placement and type of catheter. PROCEDURE: All...... children hospitalized from January 2000 to March 2008 with newly diagnosed ALL and with double-lumen total implantable devices (TIDs) or tunneled external catheters (TEs) were included retrospectively. We only used data related to the patient's first catheter. RESULTS: We included 98 children; 35 received...... a TID and the remaining 63 received a TE. A total number of 29,566 catheter days and 93 catheter-associated blood stream infections (CABSI) was identified. We found a CABSI rate of 3.1/1,000 catheter days (5.4/1,000 catheter days for TEs and 1.4/1,000 catheter days for TIDs, incidence rate ratio (IRR) 3...

    The purpose of this study was to report our experience of percutaneous retrieval of dislodged port catheters with concurrent use of pigtail and loop snare catheters. During a 5-year period at our institute (June 2005 to July 2010), a total of 23 dislodged port catheters were retrieved. The interval between port catheter implantation and dislodged catheter retrieval ranged from 43 days to 1,414 days (mean 586.7 days). The time of delayed retrieval ranged from 1 day to 45 days (mean 4.6 days). All dislodged catheters were retrieved with the concurrent use of pigtail and loop snare catheters via femoral venous route. The prevalence of port catheter dislodgement at our institute was 3.4%. All dislodged port catheters were removed successfully with pigtail and loop snare catheters together. No procedure-related complications were encountered, except for transient arrhythmia in two patients, which required no medication. In conclusion, the concurrent use of pigtail and loop snare catheters is a feasible and easy way for percutaneous retrieval of a dislodged central venous port catheter.

    The supraclavicular fossa ultrasound view can be useful for central venous catheter (CVC) placement. Venipuncture of the internal jugular veins (IJV) or subclavian veins is performed with a micro-convex ultrasound probe, using a neonatal abdominal preset with a probe frequency of 10 Mhz at a depth of 10-12 cm. Following insertion of the guidewire into the vein, the probe is shifted to the right supraclavicular fossa to obtain a view of the superior vena cava (SVC), right pulmonary artery and ascending aorta. Under real-time ultrasound view, the guidewire and its J-tip is visualized and pushed forward to the lower SVC. Insertion depth is read from guidewire marks using central venous catheter. CVC is then inserted following skin and venous dilation. The supraclavicular fossa view is most suitable for right IJV CVC insertion. If other insertion sites are chosen the right supraclavicular fossa should be within the sterile field. Scanning of the IJVs, brachiocephalic veins and SVC can reveal significant thrombosis before venipuncture. Misplaced CVCs can be corrected with a change over guidewire technique under real-time ultrasound guidance. In conjunction with a diagnostic lung ultrasound scan, this technique has a potential to replace chest radiograph for confirmation of CVC tip position and exclusion of pneumothorax. Moreover, this view is of advantage in patients with a non-p-wave cardiac rhythm were an intra-cardiac electrocardiography (ECG) is not feasible for CVC tip position confirmation. Limitations of the method are lack of availability of a micro-convex probe and the need for training.

    Central venous catheter (CVC) day definitions do not consider concurrent CVCs. We examined traditional CVC day counts and resultant central line-associated bloodstream infection (CLABSI) rates with a CVC day definition that included concurrent CVCs. Accounting for concurrent CVCs increased device day counts by 8.5% but only mildly impacted CLABSI rates.

    The fracture of a central venous catheter is a rare but potentially serious complication. Moreover, removal of the broken catheter pieces is considerably challenging, especially for premature infants. We report 3 case studies of the percutaneous transcatheter retrieval of broken catheter parts in 3 premature infants. We confirmed the location of the catheter fragments via a DSA venogram with diluted contrast media. Using the minimum amount of contrast, and extreme caution, we made certain no contrast-induced nephrotoxicity of air embolism occurred during catheter manipulation. In addition, when the broken fragment was curled or attached to the cardiac wall, we used a hook-shaped catheter to facilitate the capturing of the catheter with a loopsnare. This report demonstrates the feasibility of removing a retained catheter fragment in a premature infant using a percutaneous transcatheter approach.

    Introduction: Central venous catheter placement is an effective alternative vascular access for dialysis in patients with chronic renal failure. The purpose of this study was to evaluate the insertion of central venous catheters for hemodialysis using angiographic techniques in patients with previous multiple catheterizations in terms of efficacy of the procedure and early complications. Materials and methods: Between 2008 and 2010, the vascular access team of our hospital placed 409 central venous catheters in patients with chronic renal failure. The procedure was performed using the Seldinger blind technique. In 18 (4.4%) cases it was impossible to advance the guidewire, and so the patients were transported to the angiography suite. Results: Using the angiographic technique, the guidewire was advanced in order to position the central venous catheter. The latter was inserted into the subclavian vein in 12 (66.6%) cases, into the internal jugular vein in 4 (22.2%) and into the femoral vein in 2 (11.1%) cases. There was only one complicated case with severe arrhythmia in 1 (5.5%) patient. Conclusion: Our results suggest that insertion of central venous catheters using angiographic techniques in hemodialysis patients with previous multiple catheterizations is a safe and effective procedure with few complications and high success rates.

    We present a 6-year-old girl with acute lymphoblastic leukemia who demonstrated on chest X-ray a radiopacity in the superior vena cava after removal of an implanted venous access device. This radiopacity was initially thought to be a retained catheter fragment. On review of previous imaging, we were able to document the temporal development of a calcified catheter cast as distinct from the catheter. This case represents a rare consequence of central venous catheterization in children. Knowledge of this finding as a possible complication may help avoid performance of unnecessary follow-up imaging or invasive procedures.

    Long-term utilization of central venous catheters (CVCs) for parenteral nutrition has a high incidence of central venous complications including infections, occlusions, and stenosis. We report the case of a 31-year-old woman presenting with a malabsorption caused by short gut syndrome due to congenital aganglionic megacolon. The patient developed a chronic occlusion of all central neck and femoral veins due to long-term use of multiple CVCs over more than 20 years. In patients with central venous occlusion and venous transformation, the implantation of a totally implanted port system by accessing collateral veins is an option to continue long-term parenteral nutrition when required. A 0.014-in. Whisper guidewire (Terumo, Tokyo) with high flexibility and steerability was chosen to maneuver and pass through the collateral veins. We suggest this approach to avoid unfavorable translumbar or transhepatic central venous access and to conserve the anatomically limited number of percutaneous access sites.

    Full Text Available Context: Central venous catheter-related bloodstream infection (CRBSI is associated with high rates of morbidity and mortality in critically ill patients. Aims: This study was conducted to determine the incidence of central venous catheter-related infections (CRIs and to identify the factors influencing it. So far, there are very few studies that have been conducted on CRBSI in the intensive care unit in India. Settings and Design: This was a prospective, observational study carried out in the medical intensive care unit (MICU over a period of 1 year from January to December 2004. Materials and Methods: A total of 54 patients with indwelling central venous catheters of age group between 20 and 75 years were included. The catheters were cultured using the standard semiquantitative culture (SQC method. Statistical analysis used SPSS-10 version statistical software. Results: A total of 54 CVC catheters with 319 catheter days were included in this study. Of 54 patients with CVCs studied for bacteriology, 39 (72.22% catheters showed negative SQCs and also negative blood cultures. A total of 15 (27.77% catheters were positive on SQC, of which 10 (18.52% were with catheter-associated infection and four (7.41% were with catheter-associated bacteremia; the remaining one was a probable catheter-associated bacteremia.

    Full Text Available We present two cases of misplaced central venous catheters having in common theabsence of free blood return from one lumen immediately after placement. The former is acase of right hydrothorax associated with central venous catheterization with the catheter tipin intra-pleural location. In this case the distal port was never patent. In the latter case therewas an increased aspiration pressure through the middle port due to a catheter looping.The absence of free flow on aspiration from one lumen of a central catheter should not beundervalued. In these circumstances the catheter should not be used and needs to be removed.

    Background: Central venous catheters (CVCs) are inserted in many critically ill patients, but there is no gold standard in estimating their approximate depth of insertion. Many techniques have been described in literature. In this study, we compare the topographic method with the standard formula technique. Materials and Methods: 260 patients, in whom central venous catheterization was warranted, were randomly assigned to either topographic method or formula method (130 in each group). The position of the CVC tip in relation to carina was measured on a postprocedure chest X-ray. The primary endpoint was the need for catheter repositioning. Results: The majority of the CVCs tips positioned by the formula method were situated below the carina, and 68% of these catheters required repositioning after obtaining postprocedure chest X-ray (P formula approach in estimating the depth of insertion of right internal jugular CVCs.

    The aim of this study was to predict the optimal depth for insertion of a left-sided central venous catheter in children. Using 3D chest computed tomography angiography, we measured the distance from a point where the internal jugular vein is at the superior border of the clavicle, and from a point where the subclavian vein is inferior to the anterior border of the clavicle, to the junction of the superior vena cava and the right atrium in 257 children. Linear regression analysis revealed that the distances correlated with age, weight and height. Simple formulae for the depth of a central venous catheter via the left internal jugular vein (0.07 × height (cm)) and the left subclavian vein (0.08 × height (cm)) were developed to predict placement of the central venous catheter tip at the junction of the superior vena cava with the right atrium. Using these fomulae, the proportion of catheter tips predicted to be correctly located was 98.5% (95% CI 96.8-100%) and 94.0% (95% CI 90.8-97.3%), respectively.

    Pigs are used for long-term biomedical experiments requiring repeated injections, infusions and collections of blood samples. Thus, it is necessary for vascular catheters to be indwelling to avoid undue stress to the animals and the use of restraints. We propose a refined model of percutaneous insertion of long-term central venous catheters to minimize the surgical trauma and postoperative complications associated with catheter insertion. Different sizes of needles (18 Ga versus 21 Ga) for initial puncture of the veins were compared. In conventional pigs weighing less than 30 kg, catheter insertion may be facilitated by using a microintroducer set with a 21 Ga needle. In pigs weighing 50 kg, a standard 18 Ga needle may be preferable.

    Full Text Available Background and Aim: Central venous catheters (CVC are important in the management of critically ill patients. Incorrect positioning may lead to many serious complications. Chest radiograph is a convenient means of determining the correct position of the catheter tip. The present study was designed to evaluate the depth of CVC placed through the right and left internal jugular vein (IJV in order to achieve optimum placement of the catheter tip. Materials and Methods: A total of 107 patients in whom CVCs were put through either the right or left IJV through a central approach were included in this prospective study. Catheter tip position was observed in the post procedure chest radiograph. It was considered correct if the tip was just below the carina in the left-sided catheters and just above carina in the right-sided catheters. The catheters were repositioned based on the chest radiographs. The catheter depth leading to optimum tip placement was noted. Results: In males, catheter repositioning was required in 13 of 58 patients (22.41% in the right IJV catheters, whereas in 2 of 13 patients (15.38% in the left IJV catheters. In females, repositioning was required in 12 of 25 patients (48% in the right IJV catheters and 2 of 11 patients (18.18% in the left IJV catheters. Repositioning rate was higher in females (14/36 compared with males (15/71, which was statistically significant ( P = 0.05, 95% CI. Repositioning rates were significantly higher in females (12/25 as compared with males (13/58 in the right IJV catheters ( P = 0.019, 95% CI. Conclusion: By cannulating the IJV through a central approach, the catheters can be fixed at a length of 12-13 cm in males and 11-12 cm in females in the right IJV and at a length of 13-14 cm in males and 12-13 cm in females in the left IJV in order to achieve correct positioning.

    Objectives: This study aimed to assess the technical success, safety and immediate and delayed complications of double-lumen tunnelled cuffed central venous catheters (TVCs) at the Sultan Qaboos University Hospital (SQUH), Muscat, Oman. Methods: This retrospective study took place between January 2012 and October 2013. The clinical records and radiological data of all patients who underwent ultrasound- and fluoroscopy-guided TVC placement at SQUH during the study period were reviewed. Demographic data and information regarding catheter placement, technical success and peri- and post-procedure complications (such as catheter-related infections or thrombosis) were collected. Results: A total of 204 TVCs were placed in 161 patients. Of these, 68 were female (42.2%) and 93 were male (57.8%). The mean age of the patients was 54.4 ± 17.3 years. The most common reason for catheter placement was the initiation of dialysis (63.4%). A total of 203 procedures were technically successful (99.5%). The right internal jugular vein was the most common site of catheter placement (74.9%). Mild haemorrhage which resolved spontaneously occurred in 11 cases (5.4%). No other complications were observed. Subsequent follow-up data was available for 132 catheters (65.0%); of these, thrombosis-related catheter malfunction was observed in 22 cases (16.7%) and catheter-related infection in 29 cases (22.0%). Conclusion: Radiological-guided placement of tunnelled haemodialysis catheters can be performed safely with excellent technical success. The success rate of catheter insertion at SQUH was favourable in comparison with other studies reported in the literature. PMID:26629377

Several cases have been reported in the literature together with an explanation of the mechanism. To describe three premature babies with their PCVCs inserted through the left saphenous vein that ended up in the lumbar spinal dural venous plexus. Plain radiographs obtained to check positions showed an unusual 360 curl of the PCVC in the left inguinal area.

    PurposeEntrapment of central venous catheters (CVC) at the superior vena cava (SVC) cardiopulmonary bypass cannulation site by closing purse-string sutures is a rare complication of cardiac surgery. Historically, resternotomy has been required for suture release. An endovascular catheter release approach was developed.Materials and MethodsFour cases of CVC tethering against the SVC wall and associated resistance to removal, suggestive of entrapment, were encountered. In each case, catheter removal was achieved using a reverse catheter fluoroscopically guided over the suture fixation point between catheter and SVC wall, followed by the placement of a guidewire through the catheter. The guidewire was snared and externalized to create a through-and-through access with the apex of the loop around the suture. A snare placed from the femoral venous access provided concurrent downward traction on the distal CVC during suture release maneuvers.ResultsIn the initial attempt, gentle traction freed the CVC, which fractured and was removed in two sections. In the subsequent three cases, traction alone did not release the CVC. Therefore, a cutting balloon was introduced over the guidewire and inflated. Gentle back-and-forth motion of the cutting balloon atherotomes successfully incised the suture in all three attempts. No significant postprocedural complications were encountered. During all cases, a cardiovascular surgeon was present in the interventional suite and prepared for emergent resternotomy, if necessary.ConclusionAn endovascular algorithm to the “entrapped CVC” is proposed, which likely reduces risks posed by resternotomy to cardiac surgery patients in the post-operative period.

    Full Text Available Introduction. Pericardial effusion (PCE and tamponade can cause significant morbidity and mortality in neonates. Such cases have been reported in the literature in various contexts. Case Presentation. A 6-day old neonate with meconium aspiration syndrome and persistent pulmonary hypertension of newborn on high frequency oscillator ventilation and inhaled nitric oxide was referred to our hospital with a large pericardial effusion causing hemodynamic compromise. Prompt pericardiocentesis led to significant improvement in the cardio-respiratory status and removal of the central line prevented the fluid from reaccumulating. Cellular and biochemical analysis aided in the diagnosis of catheter related etiology with possibility of infusate diffusion into the pericardial space. Conclusion. We present this paper to emphasize the importance of recognizing this uncommon but serious complication of central venous catheters in intensive care units. We also discuss the proposed hypothesis for the mechanism of production of PCE.

    Abstract Objective: to identify the model, average length of stay on site and complications of central venous catheter in patients undergoing transplant of hematopoietic stem cells and verify the corresponding relationship between the variables: age, gender, medical diagnosis, type of transplant, implanted catheter and insertion site. Method: a retrospective and quantitative study with a sample of 188 patients transplanted records between 2007 and 2011. Results: the majority of patients used Hickman catheter with an average length of stay on site of 47.6 days. The complication fever/bacteremia was significant in young males with non-Hodgkin's lymphoma undergoing autologous transplant, which remained with the device for a long period in the subclavian vein. Conclusion: nurses should plan with their team the minimum waiting time, recommended between the catheter insertion and start of the conditioning regimen, as well as not to extend the length of time that catheter should be on site and undertake their continuing education, focusing on the prevention of complications.

    AIM: To establish the relationship between the tip position of tunnelled central venous catheters (CVC) and the incidence of venous thrombosis. MATERIALS AND METHODS: A randomly sampled, retrospective review of 428 CVC inserted into 334 patients was performed. The chest radiograph obtained post-catheter insertion, as well as follow-up radiographs, linograms, venograms and Doppler ultrasounds (US), were reviewed. RESULTS: The median follow-up was 72 days (range 1-720 days), with a total follow-up of 23,040 line days. Venous thrombosis occurred in five out of 191 (2.6%) CVC in a distal position (distal third of the superior vena cava (SVC) or right atrium (RA)), five of 95 (5.3%) in an intermediate position (middle third of the SVC) and 20 of 48 (41.7%) in a proximal position (proximal third SVC or thoracic inlet veins). There was a significant difference in thrombosis rate between lines sited with the tip in a distal compared with a proximal position (p<0.0005). CVC with tips in a proximal position were 16 times more likely to thrombose than those in a distal position. None of the 58 CVC with the tip located in the RA thrombosed or caused complications. CONCLUSION: Distal placement of tunnelled CVC, either in the distal third of the SVC or proximal RA is optimal.

    Objective: To evaluate dialysis history, imaging findings and outcome of endovascular treatment in six patients with central venous stenosis without a history of previous catheter placement. Material and methods: Between April 2000 and June 2004, six (10%) of 57 haemodialysis patients had stenosis of a central vein without a previous central catheter placement. Venography findings and outcome of endovascular treatment in these six patients were retrospectively evaluated. Patients were three women (50%) and three men aged 32-60 years (mean age: 45 years) and all had massive arm swelling as the main complaint. The vascular accesses were located at the elbow in five patients and at the wrist in one patient. Results: Three patients had stenosis of the left subclavian vein and three patients had stenosis of the left brachiocephalic vein. The mean duration of the vascular accesses from the time of creation was 25.1 months. Flow volumes of the vascular access were very high in four patients who had flow volume measurement. The mean flow volume was 2347 ml/min. One of three patients with brachiocephalic vein stenosis had compression of the vein by the brachiocephalic artery. All the lesions were first treated with balloon angioplasty and two patients required stent placement on long term. Number of interventions ranged from 1 to 4 (mean: 2.1). Symptoms resolved in five patients and improved in one patient who had a stent placed in the left BCV. Conclusion: Central venous stenosis in haemodialysis patients without a history of central venous catheterization tends to occur or be manifested in patients with a proximal permanent vascular access with high flow rates. Balloon angioplasty with or without stent placement offers good secondary patency rates in mid-term.

    Catheter rupture during CT angiography has prompted policies prohibiting the use of electronic injectors with peripherally inserted central venous catheters (PICCs) not only for CT but also for MRI. Consequently, many institutions mandate hand injection for MR angiography, limiting precision of infusion rates and durations of delivery. To determine whether electronic injection of gadolinium-based contrast media through a range of small-caliber, single-lumen PICCs would be safe without risk of catheter rupture over the range of clinical protocols and determine whether programmed flow rates and volumes were realized when using PICCs for contrast delivery. Experiments were performed and recorded using the Medrad Spectris Solaris EP MR Injection System. PICC sizes, contrast media and flow rates were based on common institutional protocols. No catheters were damaged during any experiments. Mean difference between programmed and delivered volume was 0.07 {+-} 0.10 mL for all experiments. Reduced flow rates and prolonged injection durations were observed when the injector's pressure-limiting algorithm was triggered, only in protocols outside the clinical range. PICCs commonly used in children can withstand in vitro power injection of gadolinium-based contrast media at protocols significantly above clinical levels. (orig.)

    Ankylosing spondylitis (AS) can be challenging for anesthesiologists because central venous access can be difficult, and the airway can be blocked due to the fixed flexion deformity of the spine. In this case, we attempted central access via the right subclavian vein, but the catheter was repeatedly inserted into the azygos vein, which was confirmed by radiology. After several attempts, the catheter position was corrected at the superior vena cava-atrial junction. Although several useful devi...

    A percutaneous 27-gauge OD central venous catheter was inserted at 4 +/- 3 (SD) days of age and left in place for up to 2 weeks in 20 neonates with birth weights less than 1200 g and greater than 24 h of age. Parenteral nutritional solutions and medications were administered through these catheters. Twenty neonates matched for birth weight and gestational age served as paired controls. In vitro studies demonstrate that the maximum infusion rate for parenteral nutrition solutions is about 20 ml/hr. Packed red blood cells could not be infused through these catheters. In vivo results demonstrate a significant (p less than 0.05) reduction in number of peripheral iv catheters inserted during study (2 +/- 1 vs 7 +/- 4, SD) with no difference in cost per day of iv access ($79.42 +/- 113.51 vs $43.91 +/- 15.99, SD). Two-dimensional ultrasound assessment of catheter thrombosis was unsuccessful. Moreover, there was no correlation between angiographic and electron microscopic evaluation of catheter tip thrombosis. Electron microscopy of catheter tips revealed 33% with complete, partial and no occlusion, respectively, and 39% with sheath thrombosis. In summary, percutaneous insertion of a 27-gauge OD Vialon central venous catheter is a feasible alternative in providing venous access in very low birth weight infants. PMID:2112646

    Central line-associated bloodstream infection (CLABSI) is the major complication of central venous catheters (CVC). The aim of the study was to test the effectiveness of a hospital-wide strategy on CLABSI reduction. Between 2008 and 2011, all CVCs were observed individually and hospital-wide at a large university-affiliated, tertiary care hospital. CVC insertion training started from the 3rd quarter and a total of 146 physicians employed or newly entering the hospital were trained in simulator workshops. CVC care started from quarter 7 and a total of 1274 nurses were trained by their supervisors using a web-based, modular, e-learning programme. The study included 3952 patients with 6353 CVCs accumulating 61,366 catheter-days. Hospital-wide, 106 patients had 114 CLABSIs with a cumulative incidence of 1.79 infections per 100 catheters. We observed a significant quarterly reduction of the incidence density (incidence rate ratios [95% confidence interval]: 0.92 [0.88-0.96]; P<0.001) after adjusting for multiple confounders. The incidence densities (n/1000 catheter-days) in the first and last study year were 2.3/1000 and 0.7/1000 hospital-wide, 1.7/1000 and 0.4/1000 in the intensive care units, and 2.7/1000 and 0.9/1000 in non-intensive care settings, respectively. Median time-to-infection was 15 days (Interquartile range, 8-22). Our findings suggest that clinically relevant reduction of hospital-wide CLABSI was reached with a comprehensive, multidisciplinary and multimodal quality improvement programme including aspects of behavioural change and key principles of good implementation practice. This is one of the first multimodal, multidisciplinary, hospital-wide training strategies successfully reducing CLABSI. PMID:24714418

    Background Complications associated with central venous catheters (CVCs) increase over time. Although early removal of unnecessary CVCs is important to prevent complications, the extent to which clinicians are aware that their patients have a CVC is unknown. Objective To assess how often clinicians were aware of the presence of triple-lumen or peripherally inserted central catheters (PICCs) in hospitalized patients. Design Multicenter, cross-sectional study. Setting Three academic medical centers in the United States. Patients Hospitalized medical patients in intensive care unit (ICU) and non-ICU settings. Measurements To ascertain awareness of CVCs, we first determined whether a PICC or triple-lumen catheter was present; clinicians were then queried about device presence. Differences in device awareness among clinicians were assessed by chi-square tests. Results 990 patients were evaluated, and 1881 clinician assessments were done. The overall prevalence of CVCs was 21.1% (n = 209), of which 60.3% (126 of 209) were PICCs. A total of 21.2% (90 of 425) of clinicians interviewed were unaware of the presence of a CVC. Unawareness was greatest among patients with PICCs, where 25.1% (60 of 239) of clinicians were unaware of PICC presence. Teaching attendings and hospitalists were more frequently unaware of the presence of CVCs than interns and residents (25.8% and 30.5%, respectively, vs. 16.4%). Critical care physicians were more likely to be aware of CVC presence than general medicine physicians (12.6% vs. 26.2%; P = 0.003). Limitations Awareness was determined at 1 point in time and not linked to outcomes. Patient length of stay and indication for CVC were not recorded. Conclusion Clinicians are frequently unaware of the presence of PICCs and triple-lumen catheters in hospitalized patients. Further study of mechanisms that ensure that clinicians are aware of these devices so that they may assess their necessity seems warranted. Primary Funding Source None. PMID

    Prescription of thromboprophylaxis is not a common practice in pediatric intensive care units. Most thrombi are catheter-related and asymptomatic, without causing acute complications. However, chronic complications of these (a)symptomatic catheter-related thrombi, that is, postthrombotic syndrome (PTS) and residual thrombosis have not been studied. To investigate these complications, critically ill children of 1 tertiary center with percutaneous inserted femoral central venous catheters (FCVCs) were prospectively followed. Symptomatic FCVC-thrombosis occurred in 10 of the 134 children (7.5%; 95% confidence interval [CI], 2.4-9.5). Only FCVC-infection appeared to be independently associated (P=0.001) with FCVC-thrombosis. At follow-up 2 of the 5 survivors diagnosed with symptomatic thrombosis developed mild PTS; one of them had an occluded vein on ultrasonography. A survivor without PTS had a partial occluded vein at follow-up. Asymptomatic FCVC-thrombosis occurred in 3 of the 42 children (7.1%; 95% CI, 0.0-16.7) screened by ultrasonography within 72 hours after catheter removal. At follow-up, mild PTS was present in 6 of the 33 (18.2%; 95% CI, 6.1-30.3) screened children. Partial and total vein occlusion was present in 1 (3%) and 4 (12%) children, respectively. In conclusion, children on pediatric intensive care units are at risk for (a)symptomatic FCVC-thrombosis, especially children with FCVC-infection. Chronic complications of FCVC-thrombosis are common. Therefore, thromboprophylaxis guidelines are warranted in pediatric intensive care units to minimize morbidity as a result of FCVC-thrombosis.

    2013-01-01

    Full Text Available A central venous catheter (CVC is inserted for measurement of haemodynamic variables, delivery of nutritional supplements and drugs and access for haemodialysis and haemofiltration. Catheterization and maintenance are common practices and there is more to the technique than routine placement as evident when a procedure-related complication occurs. More than 15% of the patients who receive CVC placement have some complications and infectious endocarditis involving the tricuspid valve is a rare and serious complication with high morbidity and mortality. Overenthusiastic and deep insertion of the guide wire and forceful injection through the CVC may lead to injury of the tricuspid valve and predispose to bacterial deposition and endocarditis. We report a case of tricuspid valve endocarditis, probably secondary to injury of the anterior tricuspid leaflet by the guide wire or the CVC that required open heart surgery with vegetectomy and repair of the tricuspid valve.

    Central venous catheter-related blood stream infections (CR-BSIs) are a serious complication in patients with hematological malignancies. However, it remains unclear whether there is a difference in the rate of CR-BSI associated with the conventional type of central venous catheters (cCVCs) and peripherally inserted CVCs (PICCs) in such patients. To address this question, we retrospectively investigated the incidence of CR-BSIs associated with PICCs versus cCVCs in patients with hematological malignancies. We used PICCs in all consecutive patients requiring CVC placement between February 2009 and February 2013. We compared the CR-BSI rate in patients with PICCs with that in patients with cCVCs treated between September 2006 and January 2009 (control group). Eighty-four patients received PICCs and 85 received cCVCs. The most common reason for removal due to catheter-related complications was CR-BSI. The CR-BSI rate in the PICC group was significantly lower than that in the cCVC group (PICCs: 1.23/1000 catheter days; cCVCs: 5.30/1000 catheter days; P Catheter-related complications other than CR-BSIs occurred at an extremely low rate in the PICC group. The median catheter-related complication-free survival duration was significantly longer in the PICC group than in the cCVC group. Our study shows that PICCs are useful in patients with hematological malignancies.

    Full Text Available Hematopoietic stem cells are usually transfused through a central venous catheter (CVC, which also facilitates administration of medications and intravenous fluids. We had observed high rate of catheter-related blood-stream infection (CR-BSI at our Bone Marrow Transplantation (BMT unit despite prescribing fluoroquinolones for anti-bacterial prophylaxis. Accordingly, we implemented prophylactic use of a relatively inexpensive broad spectrum antibiotic, namely doxycycline to address this problem. We wanted to investigate whether doxycycline prophylaxis reduces CR-BSI rate. Data was collected retrospectively on 54 consecutive patients, 26 of whom received doxycycline (doxycycline group, and we compared their outcomes to a previous cohort of 28 patients who did not receive doxycycline (comparison group. The groups were comparable in regards to age, gender, hematopoietic cell transplant type, and primary diagnosis. No CVC infection (0% was observed in the doxycycline group, while 5 infection episodes (18.5% occurred in 4 patients in the comparison group (p<0.001. Episodes of CR-BSI were due to: Escherichia-coli (EC=1, coagulase-negative Staphylococcus-spp (CNSS=2, both EC & CNSS=1. Our results demonstrate that CR-BSI was reduced significantly after introducing doxycycline. This finding suggests a beneficial role for systemic use of doxycycline prophylaxis to prevent CR-BSI in adult BMT patients. Nevertheless, a randomized controlled study is warranted to confirm these findings.

    Children who require long-term parenteral nutrition (PN) have central venous catheters (CVCs) in place to allow the safe and effective infusion of life-sustaining fluids and nutrition. Many consider recreational swimming to be a common part of childhood, but for some, the risk may outweigh the benefit. Children with CVCs may be at increased risk of exit site, tunnel, and catheter-related bloodstream infections (CRBSIs) if these catheters are immersed in water. The purpose of this review is to evaluate the current literature regarding the risk of infection for patients with CVCs who swim and determine if there is consensus among home PN (HPN) programs on this controversial issue. A total 45 articles were reviewed and 16 pediatric HPN programs were surveyed regarding swimming and CVCs. Due to the limited data available, a firm recommendation cannot be made. Recreational water associated outbreaks are well documented in the general public, as is the presence of human pathogens even in chlorinated swimming pools. As a medical team, practitioners can provide information and education regarding the potential risk, but ultimately the decision lies with the parents. If the parents decide swimming is worth the risk, they are encouraged to use products designed for this use and to change their child's dressing immediately after swimming. Due to our experience with a fatal event immediately after swimming, we continue to strongly discourage patients with CVCs from swimming. Further large and well-designed studies regarding the risk of swimming with a CVC are needed to make a strong, evidence-based recommendation.

    ABSTRACT: BACKGROUND: Catheters are the most common cause of nosocomial infections and are associated with increased risk of mortality, length of hospital stay and cost. Prevention of infections and fast and correct diagnosis is highly important. METHODS: In this study traditional semiquantitative...... culture-dependent methods for diagnosis of bacteria involved in central venous catheter-related infections as described by Maki were compared with the following culture-independent molecular biological methods: Clone libraries, denaturant gradient gel electrophoresis, phylogeny and fluorescence in situ...... observed on most of the catheters and were much more common than the cultivation-dependent methods indicated. CONCLUSION: The results show that diagnosis based on molecular methods improves the detection of microorganisms involved in central catheter-related infections. The importance...

    Central venous catheterization is widely used in patients on hemodialysis. A rare complication associated with the clinical use of central venous catheters is perforation of the heart or major vessels. We report a case of inadvertent perforation of the left atrium and thrombosis after the placement of a hemodialysis catheter in the right internal jugular vein. In such cases, surgical removal of the central venous catheter from perforation sites in the heart and vessel walls poses anesthetic challenges because of the high risk of pneumothorax, hemorrhage, arrhythmias, thrombosis, and death.

    Full Text Available Abstract Background To optimize the fluid status of adult patients with severe malaria, World Health Organization (WHO guidelines recommend the insertion of a central venous catheter (CVC and a target central venous pressure (CVP of 0-5 cmH2O. However there are few data from clinical trials to support this recommendation. Methods Twenty-eight adult Indian and Bangladeshi patients admitted to the intensive care unit with severe falciparum malaria were enrolled in the study. All patients had a CVC inserted and had regular CVP measurements recorded. The CVP measurements were compared with markers of disease severity, clinical endpoints and volumetric measures derived from transpulmonary thermodilution. Results There was no correlation between the admission CVP and patient outcome (p = 0.67 or disease severity (p = 0.33. There was no correlation between the baseline CVP and the concomitant extravascular lung water (p = 0.62, global end diastolic volume (p = 0.88 or cardiac index (p = 0.44. There was no correlation between the baseline CVP and the likelihood of a patient being fluid responsive (p = 0.37. On the occasions when the CVP was in the WHO target range patients were usually hypovolaemic and often had pulmonary oedema by volumetric measures. Seven of 28 patients suffered a complication of the CVC insertion, although none were fatal. Conclusion The WHO recommendation for the routine insertion of a CVC, and the maintenance of a CVP of 0-5 cmH2O in adults with severe malaria, should be reconsidered.

    Full Text Available Approximately 5 million central venous catheters (CVCs are placed by physicians annually in the United States, with a complication rate of 15%.1 Guidelines and recommendations are continually being established and updated regarding CVC placement.2 While much has been done regarding training the technical skills of CVC placement using part-task trainers (i.e., mannequins, successfully finding and cannulating a central vein is but one part of the process. In fact, many steps designed to prevent untoward complications involve non-technical skills which are perhaps more important in training practitioners to safely place CVCs. First in aviation and now in healthcare, practitioners are being trained in realistic and highly interactive simulated environments so they can learn not just technical skills , but the key management and non-technical steps which make their task safer.3 One modality being used to improve performance is video gaming simulation, or "serious gaming." Gaming as a learning tool is being increasingly utilized in health care fields and can lead to better skill-based outcomes.4 As such, we have developed a game based around the placement of CVCs that will be used as a new teaching modality in a pilot program for instructing residents in safe CVC placement.

    Full Text Available Aim: The objective of this study was to critically analyze data of the National Notification System for Adverse Events and Technical Complaints (Notivisa related to central venous catheters, through an evaluation of the description of notifications recorded between 2006 and 2009. Methods: Notifications were categorized and evaluated to: (i determine the number of adverse events and technical complaints, (ii verify compliance with the classification criteria defined by the legislation, (iii reclassify notifications, when necessary, in order for them to fit in with the legal definitions, (iv verify registered companies in Brazil, (v quantify the notifications according to the registered company and product lot, and (vi identify the country of original of the notified product. Microsoft Excel® 2010 was used to categorize and systematize the data. Results: Some conceptual errors and incomplete records were found. Altogether, 228 notifications of technical complaints and 119 of adverse events were identified. Some notifications on guidewires and broken catheters were reported which led to the necessity of duplicating some medical procedures and to the occurrence of lesions/lacerations of vessels and tissue injury. Forty-seven percent of companies presented at least one notification in Notivisa and in all, 38 product lots had more than one notification. Conclusion: These data support a necessity for cooperation between all entities of the National Health Surveillance System to check compliance of this type of product and to properly report adverse events and technical complaints. It is also important to incorporate minimum standards for the management of technologies in health services, including in the acquisition of products and training of staff.

    To compare the effect of 3 kinds of different materials on the hemostasis of puncture site after central venous catheterization. Method: A selection of 120 patients with peripheral central venous catheter chemotherapy in the Affiliated Hospital of our university from January 2014 to April 2015, Randomly divided into 3 groups, using the same specification (3.5cm × 2cm) alginate gelatin sponge and gauze dressing, 3 kinds of material compression puncture point, 3 groups of patients after puncture 24 h within the puncture point of local blood and the catheter after the catheter 72 h within the catheter maintenance costs. Result: (1) The local infiltration of the puncture point in the 24 h tube: The use of alginate dressing and gelatin sponge hemostatic effect is better than that of compression gauze. The difference was statistically significant (P catheter within 72 h after insertion of the tube are lowest, compared with alginate dressing and gauze was significant (P<0.05). Conclusion: The choice of compression hemostasis material for the puncture site after PICC implantation, using gelatin sponge and gauze dressing is more effective and economic.

    Downhill esophageal varices are a rare cause of upper gastrointestinal hemorrhage. We present a case of downhill variceal bleeding due to superior vena cava thrombosis resulting from a prior central venous catheter. The patient was managed with endoscopic band ligation and later with surgical axillary vein to right atrium bypass grafting. Successful long-term resolution of varices was achieved at 1 year of follow-up. This is the longest follow-up described for combined endoscopic and surgical management in the existing literature for catheter-associated downhill varices. PMID:27807564

    Full Text Available Background and Aim: Central venous catheter (CVC insertion induces pain and discomfort to a conscious patient despite application of a local anaesthetic (LA field block and this pain can be greatly lessened by using additional analgesics. The aim of this study was to evaluate the efficacy of dexmedetomidine along with LA field infiltration in controlling pain and discomfort associated with CVC insertion. Methods: A prospective, randomised, double-blind, placebo-controlled trial of 54 patients scheduled for planned CVC insertion was undertaken. Patients were randomly assigned into two groups of 27 each, to receive either dexmedetomidine (1 μg/kg or 0.9% normal saline, along with LA field infiltration. Pain and discomfort score was measured at 5 time points. Results: The median pain score was worst for placebo group at local anaesthetic injection (6 [4-7] and at the end of procedure (5 [4-5], which was significantly attenuated in the dexmedetomidine group (4 [4-5] and 4 [3-5]; P = 0.007 and 0.040 respectively. The lower procedure related discomfort score in the immediate post-procedural period was statistically significant in dexmedetomidine group compared to placebo (4 [4-5] vs. 5 [4-6]; P = 0.008. Conclusions: Pre-procedural bolus dexmedetomidine infusion provides adequate analgesia and patient comfort for CVC insertion along LA field block. However, the tendency for excessive sedation and bradycardia associated with dexmedetomidine render it less desirable for this purpose.

    Full Text Available Central venous catheters (CVC are used commonly in clinical practice. Incidences of CVC-related right atrial thrombosis (CRAT are variable, but, when right atrial thrombus is present, it carries a mortality risk of 18% in hemodialysis patients and greater than 40% risk in nonhemodialysis patients. Different pathogenic mechanisms have been postulated for the development of CRAT, which includes mechanical irritation of the myocardial wall, propagation of intraluminal clot, hypercoagulability, and hemodynamics of right atria. Presentation of CRAT may be asymptomatic or may be associated with one of the complications of CRAT like pulmonary embolism, systemic embolism, infected thrombi, or hemodynamic compromise. There are no established treatment guidelines for CRAT. We describe an interesting case of a 59-year-old asymptomatic male successfully treated with open heart surgery after failure of medical treatment for a large CRAT discovered during a preoperative evaluation for a kidney transplant. Our case underscores that early detection of CRAT may carry a favorable prognosis as opposed to waiting until catastrophic complications arise. It also underscores the importance of transesophageal echocardiography in the detection of thrombus and perhaps guides clinicians on which treatment modality to be used according to the size of the thrombus.

    Full Text Available The objective was to identify the average total cost (ATC for installing and turning off hemodialysis on patients with central venous catheters. This quantitative, exploratory, and descriptive research, in the mode of a single-case study, was conducted in a public university hospital. The non-probabilistic sample corresponded to the observation of 100 installations and 100 terminations of hemodialysis on 42 patients during 23 days of collection. The ATC was calculated by multiplying the time spent by nurses by the unit cost of direct labor, and adding the cost of materials, solutions, and medications. The Brazilian currency (R$ was used for the calculations. The ATC for installation was R$ 80.10 and for shutting off was R$ 13.04, totaling R$ 93.14 per hemodialysis session. The results obtained will facilitate a better planning of the allocation of human, material, and financial resources enabling the increase of managerial strategies aimed at economic efficiency. doi: 10.5216/ree.v16i4.23044.

    Full Text Available Backgraund/Aim. Hemodialysis catheter, as an integral part of hemodialysis, is a catheter placed into the jugular, subclavian and femoral vein. The most common catheter-related complications are infections and thrombosis. The aim of the study was to analyze the prevalence of complications associated with differently inserted central-vein catheters for hemodialysis. Methods. The study was organized as a prospective examination during the period from December 2003 to November 2006, and included all patients who needed an active depuration by hemodialysis, hospitalized at the Clinical Center Kragujevac. The subject of the study were 464 centralvein catheters inserted during the mentioned period and there were recorded all complications related to the placement and usage of catheters. Results. The largest percent of inserted catheters was into the femoral vein − 403 (86.8%, significantly less into the jugular vein − 42 (9.2%, while into the subclavian vein there were placed only 19 catheters (4%. The average of femoral catheter functioning was 17 catheter days, in jugular catheters it was 17.3 days while the subclavian catheters had an average rate of functioning of 25.9 catheter days; there was found a statistically significant difference regarding the duration of functioning (p = 0.03. By microbe colonization of smear culture of the skin at the catheter insertion site, in clinically present suspicion of catheter infection, there was obtained a positive finding in 5.5% of catheters placed into the femoral vein and 7.1% of catheters instilled into the jugular vein, of which Staphylococcus aureus was the most important bacterial type, without statistically significant difference (p = 0.51. Haemoculture, done when there was a suspicion of bacteriemia, was positive in 3.7% of the patients with femoral and 4.8% with jugular catheters; Staphylococcus aureus was the most common bacteria type, but there was no statistically significant difference (p

    Full Text Available Backgound and Objectives: Infections related to central venous catheter (CVC use constitute an important a problem. It is estimated that approximately 90% of bloodstream infections (BSI are caused by CVC use. This study aims at reviewing the risk factors and current recommendations for prevention of infections associated with central venous catheter use. Methods: A total of 12 articles published in the last 5 years and indexed in the databases of the Latin American and Caribbean Literature on Health Sciences (LILACS, Nursing Database (BDENF, International Literature on Health Sciences (Medline/Pubmed were selected, as well as publications related to the recommendations for BSI prevention, such as: Institute for Healthcare Improvement (IHI, Centers for Disease Control and Prevention (CDC and the National Health Surveillance Agency (ANVISA. Results: Two categories were identified: prevention and control measures and risk factors for BSI associated with central venous catheter use. Conclusions: Some recommendations that were well-defined over the years have been questioned by some authors and continuing training and education of the multidisciplinary team are the most important factors for the prevention of bloodstream infections associated with CVC use.

    Purpose: To compare the success and immediate complication rates of the anatomical landmark method (group 1) and the radiologically (combined real-time ultrasound and fluoroscopy) guided technique (group 2) in the placement of central venous catheters in emergent hemodialysis patients. Material and Methods: The study was performed prospectively in a randomized manner. The success and immediate complication rates of radiologically guided placement of central venous access catheters through the internal jugular vein (n = 40) were compared with those of the anatomical landmark method (n 40). The success of placement, the complications, the number of passes required, and whether a single or double-wall puncture occurred were also noted and compared. Results: The groups were comparable in age and sex. The indication for catheter placement was hemodialysis access in all patients. Catheter placement was successful in all patients in group 2 and unsuccessful in 1 (2.5%) patient in group 1. All catheters functioned adequately and immediately after the placement (0% initial failure rate) in group 2, but 3 catheters (7.5% initial failure rate) were non-functional just after placement in group 1. The total number of needle passes, double venous wall puncture, and complication rate were significantly lower in group 2. Conclusion: Percutaneous central venous catheterization via the internal jugular vein can be performed by interventional radiologists with better technical success rates and lower immediate complications. In conclusion, central venous catheterization for emergent dialysis should be performed under both real-time ultrasound and fluoroscopic guidance.

    Full Text Available Abstract Background Catheters are the most common cause of nosocomial infections and are associated with increased risk of mortality, length of hospital stay and cost. Prevention of infections and fast and correct diagnosis is highly important. Methods In this study traditional semiquantitative culture-dependent methods for diagnosis of bacteria involved in central venous catheter-related infections as described by Maki were compared with the following culture-independent molecular biological methods: Clone libraries, denaturant gradient gel electrophoresis, phylogeny and fluorescence in situ hybridization. Results In accordance with previous studies, the cultivation of central venous catheters from 18 patients revealed that S. epidermidis and other coagulase-negative staphylococci were most abundant and that a few other microorganisms such as P. aeruginosa and K. pneumoniae occasionally were found on the catheters. The molecular analysis using clone libraries and sequencing, denaturant gradient gel electrophoresis and sequencing provided several important results. The species found by cultivation were confirmed by molecular methods. However, many other bacteria belonging to the phyla Proteobacteria, Firmicutes, Actinobacteria and Bacteroidetes were also found, stressing that only a minor portion of the species present were found by cultivation. Some of these bacteria are known to be pathogens, some have not before been described in relation to human health, and some were not closely related to known pathogens and may represent new pathogenic species. Furthermore, there was a clear difference between the bacterial species found in biofilm on the external (exluminal and internal (luminal side of the central venous catheter, which can not be detected by Maki's method. Polymicrobial biofilms were observed on most of the catheters and were much more common than the cultivation-dependent methods indicated. Conclusion The results show that diagnosis

    When metal clips and venous catheters have been used the computerized tomography shows artifacts, which make it computerized tomography shows artifacts, which make it difficult to have a reliable and accurate diagnosis, because the X- raying of the metal clips and the venous catheter gives radiating lines, so called streaking. We have tested new materials for the metal clips and a new polymer to replace the substance of the venous catheter with the intention that the materials should have the same density as the normal tissues. With a new metal for the clips and a new polymer for the venous catheters, mixed with metal ions, the computerized tomography does not show streaking.

    Renal replacement treatment (RRT) is required in severe acute kidney injury, and a functioning central venous catheter (CVC) is crucial. Twenty-eight children younger than 16 years have been treated at the University Medical Centre Ljubljana between 2003 and 2012 with either acute hemodialysis (HD) and/or plasma exchange (PE), and were included in our study. The age of the patients ranged from 2 days to 14.1 years. Sixty-six CVCs were inserted (52% de novo, 48% guide wire). The sites of insertion were the jugular vein in 20% and the femoral vein in 80%. Catheters were in function from 1 day to 27 days. The most common cause for CVC removal or exchange was catheter dysfunction (50%). CVCs were mostly inserted in the femoral vein, which is the preferred site of insertion in acute HD/PE because of the smaller number of complications. PMID:27312920

    Central venous port devices made of two different polymeric materials, thermoplastic polyurethane (TPU) and silicone rubber (SiR), were compared due their material properties. Both naïve catheters as well as catheters after removal from patients were investigated. In lab experiments the influence of various chemo-therapeutic solutions on material properties was investigated, whereas the samples after removal were compared according to the implanted time in patient. The macroscopic, mechanical performance was assessed with dynamic, specially adapted tests for elasticity. The degradation status of the materials was determined with common tools of polymer characterisation, such as infrared spectroscopy, molecular weight measurements and various methods of thermal analysis. The surface morphology was analysed using scanning electron microscopy. A correlation between material properties and clinical performance was proposed. The surface morphology and chemical composition of the polyurethane catheter materials can potentially result in increased susceptibility of the catheter to bloodstream infections and thrombotic complications. The higher mechanic failure, especially with increasing implantation time of the silicone catheters is related to the lower mechanical performance compared to the polyurethane material as well as loss of barium sulphate filler particles near the surface of the catheter. This results in preformed microscopic notches, which act as predetermined sites of fracture. PMID:27552159

    Full Text Available The incidence of opportunistic infections by filamentous fungi is increasing partly due to the widespread use of central venous catheters (CVC, indwelling medical devices, and antineoplastic/immunosuppressive drugs. The case of a 13-year-old boy under treatment for acute lymphoblastic leukemia is presented. The boy was readmitted to the Pediatric Ward for intermittent fever of unknown origin. Results of blood cultures drawn from peripheral venous sites or through the CVC were compared. CVC-derived bottles (but not those from peripheral veins yielded hyaline fungi that, based on morphology, were identified as belonging to the Fusarium solani species complex. Gene amplification and direct sequencing of the fungal ITS1 rRNA region and the EF-1alpha gene confirmed the isolate as belonging to the Fusarium solani species complex. Portions of the CVC were analyzed by scanning electron microscopy. Fungi mycelia with long protruding hyphae were seen into the lumen. The firm adhesion of the fungal formation to the inner surface of the catheter was evident. In the absence of systemic infection, catheter removal and prophylactic voriconazole therapy were followed by disappearance of febrile events and recovery. Thus, indwelling catheters are prone to contamination by environmental fungi.

    Introduction: CT perfusion studies play an important role in the early detection as well as in therapy monitoring of vasospasm after subarachnoid hemorrhage. High-flow injections via central venous catheters are not recommended but may sometimes be the only possibility to obtain high-quality images. Materials and methods: We retrospectively analyzed our data for CT perfusions performed with power injection of contrast material with an iodine concentration of 400 mg/ml via the distal 16G lumen of the Arrow three and five lumen central venous catheter with preset flow rates of 5 ml/s. Results: 104 examinations with central venous catheters were evaluated (67 with five lumen and 37 with three lumen). No complications were observed. Mean flow rates were 4.4 {+-} 0.5 ml/s using the three lumen catheter and 4.6 {+-} 0.6 ml/s using the five lumen catheter respectively. The mean injection pressure measured by the power injector was 200.7 {+-} 17.5 psi for the three lumen central venous catheter and 194.5 {+-} 6.5 psi for the five lumen catheter, respectively. Conclusion: Following a strict safety protocol there were no complications associated with power injections of contrast material containing 400 mg iodine/ml with preset flow rates up to 5 ml/s via the distal 16G lumen of the Arrow multi-lumen central venous catheter. However, since power-injections are off-label use with Arrow central venous catheters, this procedure cannot be recommended until potential safety hazards have been ruled out by the manufacturer.

    Full Text Available Although central vascular catheters (CVC are indispensable in modern medicine, they are an important risk factor for primary bacteremias. We examined the incidence and risk factors associated with catheter-related bloodstream infection (CR-BSI caused by Staphylococcus aureus in surgical patients. A prospective study was carried out in the Hospital das Clínicas da Universidade Federal de Uberlândia (HC-UFU from September 2000 to December 2002. The skin insertion site, catheter tip, and blood were microbiologically analyzed. Demographics and risk factors were recorded for each patient, and cultures were identified phenotypically. Staphylococcus aureus was the most frequent pathogen, with an incidence rate of 4.9 episodes of CR-BSIs per 1,000 catheter/days. Based on logistic regression, the independent risk factors were: colonization on the insertion site =200 colony forming units (CFU/20 cm² (p=0.03; odds ratio (OR =6.89 and catheter tip (p=0.01; OR=7.95. The CR-BSI rate was high; it was mainly associated with S. aureus, and skin colonization at the insertion site and on the catheter tip were important risk factors for CR-BSI.

    Full Text Available BACKGROUND: Approximately 150 million central venous catheters (CVC are used each year in the United States. Catheter-related bloodstream infections (CR-BSI are one of the most important complications of the central venous catheters (CVCs. Our objective was to compare the in-hospital mortality when the catheter is removed or not removed in patients with CR-BSI. METHODS: We reviewed all episodes of CR-BSI that occurred in our intensive care unit (ICU from January 2000 to December 2008. The standard method was defined as a patient with a CVC and at least one positive blood culture obtained from a peripheral vein and a positive semi quantitative (>15 CFU culture of a catheter segment from where the same organism was isolated. The conservative method was defined as a patient with a CVC and at least one positive blood culture obtained from a peripheral vein and one of the following: (1 differential time period of CVC culture versus peripheral culture positivity of more than 2 hours, or (2 simultaneous quantitative blood culture with ≥ 5:1 ratio (CVC versus peripheral. RESULTS: 53 CR-BSI (37 diagnosed by the standard method and 16 by the conservative method were diagnosed during the study period. There was a no statistically significant difference in the in-hospital mortality for the standard versus the conservative method (57% vs. 75%, p = 0.208 in ICU patients. CONCLUSION: In our study there was a no statistically significant difference between the standard and conservative methods in-hospital mortality.

    Central line-associated bloodstream infection (CLABSIs) is an important healthcare-associated infection in the critical care units. It causes substantial morbidity, mortality and incurs high costs. The use of central venous line (CVL) insertion bundle has been shown to decrease the incidence of CLABSIs. Our aim was to study the impact of CVL insertion bundle on incidence of CLABSI and study the causative microbial agents in an intensive care unit in Kuwait. Surveillance for CLABSI was conducted by trained infection control team using National Health Safety Network (NHSN) case definitions and device days measurement methods. During the intervention period, nursing staff used central line care bundle consisting of (1) hand hygiene by inserter (2) maximal barrier precautions upon insertion by the physician inserting the catheter and sterile drape from head to toe to the patient (3) use of a 2% chlorohexidine gluconate (CHG) in 70% ethanol scrub for the insertion site (4) optimum catheter site selection. (5) Examination of the daily necessity of the central line. During the pre-intervention period, there were 5367 documented catheter-days and 80 CLABSIs, for an incidence density of 14.9 CLABSIs per 1000 catheter-days. After implementation of the interventions, there were 5052 catheter-days and 56 CLABSIs, for an incidence density of 11.08 per 1000 catheter-days. The reduction in the CLABSI/1000 catheter days was not statistically significant (P=0.0859). This study demonstrates that implementation of a central venous catheter post-insertion care bundle was associated with a reduction in CLABSI in an intensive care area setting.

    Peripherally inserted central catheters (PICCs) are frequently placed at the bedside. The purpose of our study was to evaluate the efficacy of the Sherlock II tip location system (Bard Access Systems, Salt Lake City, UT), which offers electromagnetic detection of the PICC tip to assist the operator in guiding the tip to a desired location. We performed a retrospective review of patients who had a bedside PICC using the Sherlock II tip location system. Three hundred seventy-five of 384 patients (97.7%) had the catheter tip positioned appropriately. Our results suggest that the Sherlock II tip location system is an efficacious system for bedside PICC placement.

    The objective of this study is to determine the catheter-related bloodstream infection (CRBSI) rate in a severely burned patient population, many of whom required prolonged use of central venous catheters (CVCs). Between January 2008 and June 2012, 151 patients underwent placement of 455 five-lumen minocycline/rifampin-impregnated CVCs. CRBSI was defined as at least one blood culture (>100,000 colonies) and one simultaneous roll-plate CVC tip culture (>15 colony forming units) positive for the same organism. Most patients had accidental burns (81.5%) with a mean TBSA of 50%. A mean of three catheters were inserted per patient (range, 1-25). CVCs were inserted in the femoral vein (91.2%), subclavian vein (5.3%), and internal jugular vein (3.3%). Mean overall catheter indwell time was 8 days (range, 0-39 days). The overall rate of CRBSI per 1000 catheter days was 11.2; patients with a TBSA >60% experienced significantly higher rates of CRBSI than patients with a TBSA ≤60% (16.2 vs 7.3, P = .01). CVCs placed through burned skin were four times more likely to be associated with CRBSI than CVCs placed through intact skin. The most common infectious organism was Acinetobacter baumannii. Deep venous thrombosis developed in eleven patients (7%). The overall rate of CRBSI was 11.2, consistent with published rates of CRBSI in burn patients. Thus, femoral placement of 5-lumen CVCs did not result in increased CRBSI rates. These data support the safety of femoral CVC placement in burn patients, contrary to the Centers for Disease Control recommendation to avoid femoral CVC insertion.

    Taurolidine has demonstrated inhibition of biofilm formation in vitro. The aim of this study was to compare the effect of catheter locking with taurolidine vs heparin in biofilm formation in central venous catheters. Forty-eight children with cancer were randomized to catheter locking by heparin (n...... = 22) or taurolidine (n = 26), respectively. After removal, catheters were examined by standardized scanning electron microscopy to assess quantitative biofilm formation. Biofilm was present if morphologically typical structures and bacterial cells were identified. Quantitative and semi......-quantitative cultures were also performed. Biofilm was identified in 23 of 26 catheters from the taurolidine group and 21 of 22 catheters from the heparin group. A positive culture was made of six of the catheters locked with taurolidine and heparin, respectively (p = 0.78). The rate of catheter-related bloodstream...

    The insertion of central venous catheters (CVCs) is an integral part of the management of critically ill patients. We aimed to study the impact of ultrasonography (USG) on CVC insertion in intensive care. A prospective study of 450 patients requiring CVC in the intensive care unit (ICU) of a tertiary care hospital. The patients were randomized into two groups: to have CVC insertion with USG-guidance or with the anatomic landmark technique (ALT). Data were collected on patient demographics; operator experience; and method, site and side of insertion. Outcome measures included successful insertion of CVC, number of attempts needed and complications. Internal jugular vein (IJV) cannulation was successful in 177/194 patients (91.2%) using ALT and in 200/205 patients (97.6%) using USG guidance, a significant difference of 6.4% (P = 0.006). Using ALT, 72.7% of cannulations could be accomplished in the first attempt as compared with 84.4% with USG guidance (P = 0.004). The overall complication rate was 28/399 (7%), with 19 (9.8%) complications in the ALT group and 9 (4.4%) in the USG group (age-, sex-, and operator-adjusted OR = 0.35, 95% CI: 0.13–0.96; P = 0.03). For subclavian vein catheterization, the success rate was 26/28 (92.9%) in the ALT group and 17/17 (100%) in the USG group (P = 0.52). Using ALT, 71.4% cannulation could be accomplished in the first attempt as compared with 82.4% under USG guidance (P = 0.49). The overall complication rate was 6/45 (13.3%), with 4 (14.3%) complications in the ALT group and 2 (11.8%) in the USG group (P > 0.99). Real-time USG guidance improves success rates, reduces the number of attempts and decreases the complications associated with CVC insertion, especially for the IJV, and should become the standard of care in intensive care

    Full Text Available Objectives: To determine the impact of an educational program on the prevention of central venous catheter-related infections in a Brazilian Pediatric Intensive Care Unit. Patients and Methods: All patients admitted to the unit between February 2004 and May 2005 were included in the cohort study in a longitudinal assessment. An educational program was developed based on the Centers for Disease Control and Prevention recommendations for prevention of catheter-associated infections and was adapted to local conditions and resources after an initial observational phase. Incidence of catheter-associated infections was measured by means of on-site surveillance. Results: One hundred eighteen nosocomial infections occurred in 253 patients (46.6 infections per 100 admissions and in 2,954 patient-days (39.9 infections per 1,000 patient-days. The incidence-density of catheter infections was 31.1 episodes per 1.000 venous central catheter-days before interventions, and 16.5 episodes per 1,000 venous central catheter-days afterwards (relative risk 0.53 [95% CI 0.28-1.01]. Corresponding rates for exit-site catheter infections were 8.0 and 2.5 episodes per 1,000 venous central catheter-days [0.32 (0.07-1.49], and the rates for bloodstream infections were 23.1 and 13.9 episodes per 1,000 venous central catheter-days, before and after interventions [0.61 (0.32-1.14]. Conclusion: A prevention strategy targeted at the insertion and maintenance of vascular access can decrease rates of vascular-access infections in pediatric intensive care unit.

    2012-01-01

    Full Text Available Central venous catheterization is a common practice in the management of critically ill patients and is associated with various complications, such as Bloodstream Infections (BSI, which are major determinants of increased morbidity, mortality and healthcare expenses. Few studies have addressed factors that predict mortality in patients with this complication. The aim of this study was to investigate factors associated with mortality in patients with Central Venous Catheter (CVC-related BSI in an intensive care unit of a tertiary care hospital in the Federal District, Brazil. This was a retrospective and observational study, in which all CVC-related BSI that occurred between January 2008 and December 2010 were reviewed. We obtained demographic, clinical, biochemical and microbiological data from medical records and investigated its association with mortality during ICU stay. There were 4,504 ICU admissions during the study period and 68 were complicated by CVC-related BSI (4.09 per 1000 catheter-days, most due to gram-negative organisms (45.6%. Overall mortality was 59.7%. Death risk was significantly associated with mechanical ventilation (OR 27.8, 95% CI 3.28-250, p-1 in survivors vs. 73.9 mg dL-1 in non-survivors, p = 0.001. Mortality was not associated with other clinical or biochemical features, neither with microbiological variables, although lethality was high among patients with gram-positive infections (77% Vs 58.33% for fungi and 54.83% for gram-negative. CVC-related BSI was associated with high absolute mortality, which was predicted by mechanical ventilation and a higher number of invasive devices other than the CVC. Knowledge of local factors predictive of mortality is critical for planning strategies to reduce death risk associated with this complication.

  12. Inadvertent arterial insertion of a central venous catheter: delayed recognition with abrupt changes in pressure waveform during surgery -A case report-.

    2011-01-01

    We present a case of inadvertent arterial insertion of a central venous catheter, identified during a pericardiectomy procedure after observing abrupt changes in pressure waveform and confirmed via arterial blood gas analysis and transesophageal echocardiography. Central venous pressure measurement was initially 20 mmHg in supine, and then elevated to 30-40 mmHg in right lateral decubitus, presumably resulting from constrictive physiology of pericarditis. The pressure waveforms, however, abruptly changed from a venous to an arterial waveform during surgery. When visual discrimination between arterial and venous blood regurgitation is unreliable, anesthesiologists should confirm that using all the available methods one has on the scene, especially after at least two unsuccessful attempts or in patients with advanced age or clinical conditions resulting in jugular venous dilation. To prevent arterial catheterization, one should limit the leftward rotation of the head by <40° and consider using ultrasound-guided method after more than two unsuccessful attempts.

    2014-10-01

    Critically ill pediatric patients, especially in the intensive care unit, receive multiple medications and have a higher risk of central venous catheter (CVC) occlusion. If an occlusion occurs immediately after the administration of multiple medications or incompatible medications, either an acidic solution such as 0.1 N hydrochloric acid (HCl) or a basic solution of 1 mEq/mL sodium bicarbonate or 0.1 N sodium hydroxide can be used. However, compounding and storing of 0.1 N HCl has become more complex due to USP guidelines for sterile compounding, and an alternative is needed. We report a series of cases in which L-cysteine was used instead of HCl to clear CVCs occluded due to administration of multiple medications. L-cysteine is a commercially available, sterile solution with a pH of 1–2.5. CVC occlusion was resolved in 10 of the 16 episodes in 13 patients. Two of the 16 occlusions were phenytoin related and would not have responded. An L-cysteine dose of 50 mg was used during 10 of the 16 episodes, 100 mg during 5 episodes, and 25 mg during 1 episode. A correlation between catheter clearance and dose was not observed. Occlusion resolution due to L-cysteine was not correlated to the prior use of tissue plasminogen activator. Metabolic acidosis, adverse effects, or damage to the catheters due to L-cysteine were not observed. On the basis of this limited experience, we propose L-cysteine as an effective alternative to 0.1 N HCl for clearing CVC occlusions caused by drugs with an acidic pKa.

    In cancer patients with long-term central venous catheters (CVC), removal and reinsertion of a new CVC at a different site might be difficult because of the unavailability of accessible vascular sites. In vitro and animal studies showed that a minocycline-EDTA-ethanol (M-EDTA-EtOH) lock solution may eradicate microbial organisms in biofilms, hence enabling the treatment of central line-associated bloodstream infections (CLABSI) while retaining the catheter in situ Between April 2013 and July 2014, we enrolled 30 patients with CLABSI in a prospective study and compared them to a historical group of 60 patients with CLABSI who had their CVC removed and a new CVC inserted. Each catheter lumen was locked with an M-EDTA-EtOH solution for 2 h administered once daily, for a total of 7 doses. Patients who received locks had clinical characteristics that were comparable to those of the control group. The times to fever resolution and microbiological eradication were similar in the two groups. Patients with the lock intervention received a shorter duration of systemic antibiotic therapy than that of the control patients (median, 11 days versus 16 days, respectively; P < 0.0001), and they were able to retain their CVCs for a median of 74 days after the onset of bacteremia. The M-EDTA-EtOH lock was associated with a significantly decreased rate of mechanical and infectious complications compared to that of the CVC removal/reinsertion group, who received a longer duration of systemic antimicrobial therapy.

  16. Comparison of two indwelling central venous access catheters in dogs undergoing fractionated radiotherapy

    International Nuclear Information System (INIS)

    Twenty dogs with neoplasms requiring multiple radiation treatments received either percutaneous vascular access catheters (PVACs; Cook, Bloomington, IN) or subcutaneous vascular access ports (SVAPs; Vascular-Access-Ports, Norfolk Medical Products, Inc., Skokie, IL); 10 dogs were entered in each group. All catheters were implanted and removed aseptically and the catheter tips were cultured during implant removal. Complications with PVACs included mild incisional swelling and redness and accidental severance or rupture of the catheter. Complications with SVAPs included incisional or port swelling, bruising or redness, hematoma formation, and pain. Ports in 4 of these dogs could not be used for 1 to 3 days after surgery because of swelling and pain. Surgical wound complications, when pooled for comparison, occurred significantly more frequently with the SVAPs (P = .023). Wound complications associated with both catheters were self-limiting and resolved within 7 days. Bacterial cultures were positive in two PVACs and four SVAP tips, however, none of these dogs had clinical signs of infection or sepsis. Although both types of indwelling catheters were functional in a clinical setting, PVACs were preferred to SVAPs for dogs undergoing radiation therapy because of decreased time for implantation and fewer overall complications

    This study was designed to compare the incidence of mechanical, thrombotic and infective complications in transjugular (IJV) and axillosubclavian (SCV) central venous catheters (CVC) in patients with hematological malignancy. In a prospective observational trial, 131 consecutive patients were classified into two groups: Group A included those with IJV catheter insertions under sonography guidance (n=61) and group B included those with SCV insertions under venography guidance (n=70). After catheter placement, patients were prospectively acquired and recorded to obtain the following data: success rates, total catheter days, and complication episodes per 100 catheter days. All procedures were technically successful. Total catheter days were 7800 (group A) versus 8391(group B). Mechanical complications were observed in three cases from group A and 11 from group B, with an incidence rate of 0.04 per 100 catheter days versus 0.13 (P=0.043), respectively. Two symptomatic thrombotic complications were observed in group B. The number of infective complications was not significantly different between the two groups (P=0.312). There was no difference in infective complication incidence between the two groups. To minimize catheter-related mechanical and thrombotic complications, however, the IJV approach is superior to the SCV approach. (orig.)

    In pLT recipients, the advantages of ICVCs need to be weighed against the risk of complications. This single-center retrospective study aimed to review ICVC complications in our cohort of pLT recipients. We performed chart reviews of pLT patients having undergone transplant between 01/2000 and 03/2014 and who underwent ICVC placement either before or after LT. We identified 100 ICVC in 85 patients. Overall observation time was 90 470 catheter-days. There was no difference in catheter lifespan between those inserted pre- or post-transplant; 46% of ICVC presented a complication. Most frequent complications were MD and infection. The infection rate was 0.09 per 1000 catheter-days, and MD rate was 0.36 per 1000 catheter-days. Patients having received technical variant grafts were more at risk of complications. To the best of our knowledge, this is the first study examining ICVC complications in pLT recipients. We conclude that ICVC have a high rate of MD. Children receiving technical variants may be more at risk of complications. By removing ICVC in a select number of patients at six months post-insertion, we might avoid as much as 60% of complications.

We retrospectively evaluated on a large cohort of patients the incidence of CVC-related early and late complications. From 7/99 to 12/2005, 1102 CVC have been implanted at our Institution in 881 patients with haematological malignancies (142,202 total day number of implanted CVC. Early mechanic complications were 79 (7.2% - 0.55/1,000 days/CVC. Thirty-nine episodes of early infective complications (<1 week from CVC implant occurred (3.5% - 0.3/1000 days/CVC: furthermore, 187 episodes of CVC-related sepsis (17% - 1.3/1000 days/CVC were recorded. There were 29 episodes (2.6% of symptomatic CVC-related thrombotic complications, with a median interval from CVC implant of 60 days (range 7 – 395. The rate of CVC withdrawal due to CVC-related complications was 26%. The incidence of CVC-related complications in our series is in the range reported in the literature, notwithstanding cytopenia often coexisting in haematological patients.

    Purpose: are implanted central venous port catheters suitable for contrast media pressure (power) injection in computed tomography? Material and methods: in an in vitro study 100 ml of contrast medium (Ultravist 370, Schering, Berlin, Deutschland) was injected through 20 different port catheter systems using a power injector (Stellant, Medrad, Inianola, USA) with a pressure limit of 325 PSI. The injection rate was increased from 2 ml/s to 10 ml/s in increments of 2 ml/s. The maximum injection pressure and maximum injection rate were assessed. Results: an injection rate of 2 ml/s was possible in all catheter systems. Injection rates of 4 ml/s in 18 systems, 6 ml/s in 13 systems and 8 ml/s in 6 systems were achieved. With a given pressure limit of 325 PSI an injection rate of 10 ml/s was not possible in any of the port catheter systems. There were no catheter ruptures, catheter disconnections or contrast extravasations noted. (orig.)

    Multilumen central venous catheters (CVCs) are not commonly used for power injection. However, in critically ill patients, CVCs - most of which do not have FDA approval for power injection - may be the only available venous access. The pitfalls of multilumen CVCs are illustrated by a case report of a patient in whom extravasation of intravenously administered contrast medium occurred after power injection in a triple-lumen CVC using the lumen with the port furthest from the catheter tip. The underlying mechanisms for the displacement of the initially correctly placed right subclavian CVC could include elevation of both arms of the obese patient or the power injection itself. The distances between port openings and catheter tips of various commercially available multilumen CVCs are assessed. We examine the possible caveats of ECG-guided CVC placement for optimal tip position, discuss technical difficulties related to power injection via CVCs, and review commonly used drugs that may cause extravasation injury. Knowledge of the distances between CVC port openings and the catheter tip are essential for safe intravasal administration of fluids. (orig.)

    Full Text Available Tamponamento cardíaco secundário ao uso de cateter venoso central é uma complicação rara, porém potencialmente tratável, quando identificada a tempo. Nós relatamos dois casos de tamponamento cardíaco, diagnosticados por ecocardiograma transtorácico, seguido de pericardiocentese de urgência e drenagem pericárdica cirúrgica como complicação de cateterização venosa umbilical. Em um caso, a ponta do cateter estava adequadamente localizada e, no outro caso, não. Em ambos os casos, solução hiperosmolar estava sendo infundida. Apesar de situação incomum, esta deve ser sempre considerada em neonato, evoluindo com choque cardiogênico sem causa aparente.Cardiac tamponade secondary to the use of central venous catheter is a rare complication; however, it is potentially reversible when it is caught in time. We report two cases of cardiac tamponade that was diagnosed using a transthoracic echocardiography, followed by urgent pericardiocentesis and surgical pericardial drainage as a complication from umbilical venous catheterization. In one case, the tip of the catheter was properly placed, and in the other case, it was not. In both cases, a hyperosmolar solution was being injected. Although it may be an uncommon situation, it should be always considered as a possibility in a newborn who develops cardiogenic shock without an apparent cause.

    Full Text Available Background and Aims: The complications of central venous catheterisation can be minimized by ensuring catheter tip placement just above the superior vena cava-right atrium junction. We aimed to compare two methods, using an electrocardiogram (ECG or landmark as guides, for assessing correct depth of central venous catheter (CVC placement. Methods: In a prospective randomised study of sixty patients of <12 years of age, thirty patients each were allotted randomly to two groups (ECG and landmark. After induction, central venous catheterisation was performed by either of the two techniques and position of CVC tip was compared in post-operative chest X-ray with respect to carina. Unpaired t-test was used for quantitative data and Chi-square test was used for qualitative data. Results: In ECG group, positions of CVC tip were above carina in 12, at carina in 9 and below carina in 9 patients. In landmark group, the positions of CVC tips were above carina in 10, at carina in 4 and below carina in 16 patients. Mean distance of CVC tip in ECG group was 0.34 ± 0.23 cm and 0.66 ± 0.35 cm in landmark group (P = 0.0001. Complications occurred in one patient in ECG group and in nine patients in landmark group (P = 0.0056. Conclusion: Overall, landmark-guided technique was comparable with ECG technique. ECG-guided technique was more precise for CVC tip placement closer to carina. The incidence of complications was more in the landmark group.

    Objective: Totally implantable devices (TIDs) and external tunneled catheters (ETCs) became a basic requirement in the treatment of pediatric oncologic patients. Techniques for implantation and confirmation of proper position vary among different centers. The article presented different techniques for sonographic guided puncture of the target central vein and confirmation of the proper position of tunneled catheters. Methods: This was an observational study with a single crossover phase, in which operators initially used the open cut down technique and subsequently converted to the ultrasound guided technique. Internal jugular vein (IJV) was used in all cases. Results: In ultrasound guided group, TIDs were inserted in 121cases while ETCs were inserted in 13 cases. Ultrasound was successful in guiding IJV puncture from the first trial in all cases and in guide-wire localization in the right atrium in 132 cases. There were no reported cases of hematoma, pneumothorax,hemothorax, catheter malposition or surgical-site infection (SSI) in the perioperative period. In the open cut down group, TIDs were inserted in 119 cases. Two patients developed post operative hematoma and one of them developed SSI. The mean time of ultrasound guided TIDs was (30.04 ± 1.1) minutes which was significantly lower than the mean time of cases done by theopen cut down technique (45.4 ± 3.1) minutes (P < 0.0001). Conclusion: Ultrasound guidance is helpful for insertion of TIDs and ETCs in the IJV in pediatric oncologic patients. It minimizes the need for open cut downs and fluoroscopy.

    During three days 132 surgical patients with postoperative infusion treatment were checked on the frequency of venous reactions in the arms when catheters/cannulas of 4 different materials were used and the outcome compared. A significant result was obtained in connection with the I-cath catheter made of vialon (a polyurethanelike resin polymer) and the L-cath of polyurethane. Phlebitis was decreased to 27.3% resp. 24.2% - approximately half of its usual frequency - when I-cath of polyvinyl-chloride and FEP-teflon vasofix cannulas were applied (both 51.5%). The different predisposing factors of infusion phlebitis are under discussion. PMID:4093198

    Full Text Available Abstract Background Although several studies have demonstrated early survival advantages with peritoneal dialysis (PD over hemodialysis (HD, the reason for the excess mortality observed among incident HD patients remains to be established, to our knowledge. This study explores the relationship between mortality and dialysis modality, focusing on the role of HD vascular access type at the time of dialysis initiation. Methods A retrospective cohort study was performed among local adult chronic kidney disease patients who consecutively initiated PD and HD with a tunneled cuffed venous catheter (HD-TCC or a functional arteriovenous fistula (HD-AVF in our institution in the year 2008. A total of 152 patients were included in the final analysis (HD-AVF, n = 59; HD-TCC, n = 51; PD, n = 42. All cause and dialysis access-related morbidity/mortality were evaluated at one year. Univariate and multivariate analysis were used to compare the survival of PD patients with those who initiated HD with an AVF or with a TCC. Results Compared with PD patients, both HD-AVF and HD-TCC patients were more likely to be older (pp = 0.017 and cardiovascular disease (p = 0.020. Overall, HD-TCC patients were more likely to have clinical visits (p = 0.069, emergency room visits (ppvs. 0.93 vs. 0.64, per patient-year; pvs. 0.07 vs. 0.14, per patient-year; p = 0.034 than HD-AVF and PD patients, respectively. The survival rates at one year were 96.6%, 74.5% and 97.6% for HD-AVF, HD-TCC and PD groups, respectively (pp = 0.024. Conclusion Our results suggest that HD vascular access type at the time of renal replacement therapy initiation is an important modifier of the relationship between dialysis modality and survival among incident dialysis patients.

  20. Inadvertent Entrapment of a Central Venous Catheter by a Purse-String Suture during Cardiopulmonary Bypass: A Case Report

    Directory of Open Access Journals (Sweden)

    Abdorasoul Anvaripour

    2011-01-01

    Full Text Available A 65-year-old female patient with severe mitral valve stenosis plus coronary artery disease was scheduled for mitral valve replacement and 2-vessel coronary artery bypass graft (CABG surgeries simultaneously. After a successful procedure, resistance was met on a CVC withdrawal. During postoperative fluoroscopy, fixation of the catheter at the heart was confirmed which necessitated reopening the chest, cutting the suture, and removing the catheter. When a catheter became hard to withdraw after open heart surgery, we should never withdraw it forcefully and blindly. Although rare, one should consider inadvertent entrapment of CVC by a suture as the possible cause.

    Full Text Available Abstract Background Central venous catheters (CVCs are associated with early mortality in dialysis patients. However, some patients progress to end stage renal disease after an acute illness, prior to reaching an estimated glomerular filtration rate (eGFR at which one would expect to establish alternative access (fistula/peritoneal dialysis catheter. The purpose of this study was to determine if exclusion of this “acute start” patient group alters the association between CVCs and mortality. Methods We conducted a retrospective cohort study of 406 incident dialysis patients from 1 Jan 2006 to 31 Dec 2009. Patients were classified as acute starts if 1 the eGFR was >25 ml/min/1.73 m2, ≤3 months prior to dialysis initiation and declined after an acute event (n = 45, or 2 in those without prior eGFR measurements, there was no supporting evidence of chronic kidney disease on history or imaging (n = 12. Remaining patients were classified as chronic start (n = 349. Results 98 % and 52 % of acute and chronic starts initiated dialysis with a CVC. There were 148 deaths. The adjusted mortality hazard ratio (HR for acute vs. chronic start patients was 1.84, (95 % CI [1.19-2.85]. The adjusted mortality HR for patients dialyzing with a CVC compared to alternative access was 1.19 (95 % CI [0.80-1.77]. After excluding acute start patients, the adjusted HR fell to 1.03 (95 % CI [0.67-1.57]. Conclusions A significant proportion of early dialysis mortality occurs after an acute start. Exclusion of this population attenuates the mortality risk associated with CVCs.

    Catheters are widely used for vascular access and for the administration of drugs or fluids in critically ill patients. This exposes patients to an infection risk. Tegaderm chlorhexidine gluconate (CHG) (developed by 3M)-a transparent securement dressing-covers and protects catheter sites and secures devices to the skin. It comprises a transparent adhesive dressing to act as a barrier against external contamination and an integrated gel pad containing an antiseptic agent. The Medical Technologies Advisory Committee (MTAC) at the National Institute for Health and Care Excellence (NICE) selected Tegaderm CHG for evaluation. One study was identified by the sponsor as relevant to the decision problem. From this, the sponsor concluded that compared with standard dressings, Tegaderm CHG is associated with lower rates of catheter-related infection, but increased dermatitis incidence. The External Assessment Centre (EAC) identified four paired comparative studies between Tegaderm CHG, other CHG dressings or standard dressings. The EAC agreed with the sponsor's conclusion, finding that CHG dressings reduce infections compared with standard dressings. The sponsor constructed a de novo costing model. Tegaderm CHG generated cost savings of £77.26 per patient compared with standard dressings and was cost saving in 98.5 % of a sample of sets of inputs (2013 prices). The EAC critiqued and updated the model's inputs, yielding similar results to those the sponsor estimate. The MTAC reviewed the evidence and decided to support the case for adoption, issuing a positive draft recommendation. After a public consultation, NICE published this as Medical Technology Guidance 25. PMID:26458938

    Microorganisms may colonize needleless connectors (NCs) on intravascular catheters, forming biofilms and predisposing patients to catheter-associated infection (CAI). Standard and silver-coated NCs were collected from catheterized intensive care unit patients to characterize biofilm formation using culture-dependent and culture-independent methods and to investigate the associations between NC usage and biofilm characteristics. Viable microorganisms were detected by plate counts from 46% of standard NCs and 59% of silver-coated NCs (P=0.11). There were no significant associations (P>0.05, chi-square test) between catheter type, side of catheter placement, number of catheter lumens, site of catheter placement, or NC placement duration and positive NC findings. There was an association (P=0.04, chi-square test) between infusion type and positive findings for standard NCs. Viable microorganisms exhibiting intracellular esterase activity were detected on >90% of both NC types (P=0.751), suggesting that a large percentage of organisms were not culturable using the conditions provided in this study. Amplification of the 16S rRNA gene from selected NCs provided a substantially larger number of operational taxonomic units per NC than did plate counts (26 to 43 versus 1 to 4 operational taxonomic units/NC, respectively), suggesting that culture-dependent methods may substantially underestimate microbial diversity on NCs. NC bacterial communities were clustered by patient and venous access type and may reflect the composition of the patient's local microbiome but also may contain organisms from the health care environment. NCs provide a portal of entry for a wide diversity of opportunistic pathogens to colonize the catheter lumen, forming a biofilm and increasing the potential for CAI, highlighting the importance of catheter maintenance practices to reduce microbial contamination.

    Guidewire retention is a severe but preventable complication from central venous catheter (CVC) insertion. There were three cases of guidewire retention during CVC insertion in the medical intensive care unit (MICU) in Singapore General Hospital, in the period between December 2011 and February 2012. The primary objective of this quality improvement project was to eliminate future incidences of guidewire retention during CVC insertion in the MICU and medical intermediate care area (MICA) via a structured educational program and a cost effective modified CVC set. The secondary objective was to perform a cost analysis and comparison between the use of the conventional hospital CVC set and drape with our newly modified CVC dressing kit. Root cause analysis of the three cases identified major factors leading to guidewire retention. Interventions were planned and tested using PDSA cycles. Internal medicine trainees rotating through MICU and MICA during the period between February 2012 and June 2013 underwent a multi-modal structured CVC insertion training program with hands on simulation. They also used a newly modified CVC dressing kit and drape. The CVC dressing kit was modified (CVC PLUS) to include a sterile drape with reminder stickers stating "REMOVE the GUIDEWIRE," as well as a sterile ultrasound sleeve. The total number of CVC insertions performed and guidewire retentions were monitored. During the period of study there were 320 CVC insertions in the MICU and MICA. Since this quality improvement project was initiated, and up to the submission of this article, there have not been any further cases of guidewire retention in the MICU and MICA. The total cost reduction per use of CVC PLUS was S$29.26 (Singaporean Dollars). A multi-modal structured training program, integrated with a modified, pre-packed CVC set, and drapes with reminder stickers (all included in CVC PLUS) were cost effective, and improved patient safety by eliminating guidewire retention during CVC

    Full Text Available OBJECTIVES: To identify risk factors for short-term percutaneously inserted central venous catheter-related infections in children and to evaluate the accuracy of a mortality score in predicting the risk of infection. METHOD: After reviewing the charts of patients who developed catheter-related infection in a university hospital's pediatric intensive care unit, we conducted a case-controlled study with 51 pairs. Variables related to patients and to catheter insertion and use were analyzed. Risk factors were defined by logistic regression analysis. The accuracy of the Pediatric Risk of Mortality score to discriminate the risk for infection was tested using the Receiver Operating Characteristic curve. RESULTS: Infection was associated with respiratory failure, patient's length of stay, duration of tracheal intubation, insertion of catheter in the intensive care unit and parenteral nutrition. Insertion site (femoral or internal jugular was unimportant. Multivariate logistic regression analysis identified the following variables. Risk factors included more than one catheter placement (p=0.014 and duration of catheter use (p=0.0013, and protective factors included concomitant antibiotic use (p=0.0005 and an intermittent infusion regimen followed by heparin filling compared to continuous infusion without heparin (p=0.0002. Pediatric Risk of Mortality did not discriminate the risk of infection. CONCLUSIONS: Central parenteral nutrition and central venous catheters should be withdrawn as soon as possible. Femoral vein catheterization carries a risk of infection similar to internal jugular catheterization. The Pediatric Risk of Mortality score should not be used to predict the risk of central catheter-related infections.OBJETIVOS: Identificar fatores de risco para as infecções relacionadas a cateter venoso central de curta permanência, inserido por punção, em crianças e avaliar a eficiência de um escore de mortalidade pediátrica em prever o risco

    Only a few studies have investigated the optimal exit site management of tunneled central venous catheters (CVCs) in pediatric patients on chronic hemodialysis (HD). The aim of this study was to assess the efficacy of chlorhexidine solutions and a 5% povidone-iodine solution on the incidence of CVC-related infections in children on HD. The incidence of exit-site infection (ESI), tunnel infection (TI), and bloodstream infection (BSI) was assessed in two groups of tunneled CVCs. The iodopovidone group consisted of 14 CVCs used between 1 January 2011 and 30 June 2012 in 10 children, whose median age at the time of CVC placement was 11.8 years (range 1.2-19.2): 5% povidone-iodine was used for CVC exit-site care. From 1 August 2012 to 31 January 2014, 0.5% chlorhexidine gluconate/70% isopropyl alcohol was used for the exit site, and 2% chlorhexidine gluconate/70% isopropyl alcohol spray for the hub in 13 CVCs was used in 10 patients (chlorhexidine group), whose median age at the time of CVC placement was 10 years (range 1.2-19.2). Ten episodes of ESI were diagnosed in the iodopovidone group (incidence 3.4/1000 CVC days), and only one in the chlorhexidine group (incidence 0.36/1000 CVC days, P = 0.008). One TI was observed in the iodopovidone group (0.34/1000 CVC days), and none in the chlorhexidine group. The incidence of BSIs decreased from 1.7/1000 CVC days (5 cases) to 0.36/1000 CVC days (1 case, P = 0.06) after switching to chlorhexidine. Two CVCs were lost due to CVC-related infections in the iodopovidone group, whereas no CVC was lost due to infections in the chlorhexidine group. In comparison with 5% povidone-iodine, the use of chlorhexidine gluconate was associated with a reduction in the incidence of ESI, TI, and BSI in children on HD.

    Full Text Available Cateteres venosos de longa permanência são amplamente utilizados em pacientes com necessidade de acesso venoso por período prolongado. A infecção relacionada a esses cateteres permanece um desafio na prática clínica. Revisamos a literatura acerca da epidemiologia e tratamento das infecções relacionadas a cateteres. Staphylococcus aureus é a bactéria mais comumente isolada. Os cateteres semi-implantáveis apresentam taxas de infecção maiores que os totalmente implantáveis. O tratamento pode ser feito com locks, antibioticoterapia sistêmica e até mesmo com retirada do cateter, dependendo do tipo de infecção, do microrganismo isolado e das condições clínicas do paciente. O salvamento do cateter deve ser tentado sempre que possível.Long-term venous catheters are widely used in patients with needs of venous access for prolonged periods. The infection related to these catheters remains a challenge in clinical practice. We reviewed the literature about infection epidemiology and treatment related to catheters. Staphylococcus aureus is the most common isolated bacteria. Tunneled catheters present higher infection rates than implanted ports. Treatment may consist in the use of locks, systemic antibiotics, and even catheter removal, depending on the kind of infection, the isolated microorganism, and the patient's clinical conditions. Catheter salvation should be tried whenever possible.

    Full Text Available Insertion of central venous port (CVP catheter in the cancer population is associated with increased incidence of venous thromboembolic events (VTE. However, trials have shown limited benefit of antithrombotic treatment to prevent catheter-related venous thrombosis. This prospective observational cohort study was designed to assess the incidence of VTE closely related to CVP implantation in patients with cancer and undergoing chemotherapy, and to identify a high risk subgroup of patients. Between February 2006 and December 2011, 1097 consecutive cancer patients with first CVP implantation were included. Catheter-related VTE were defined as deep venous thrombosis in the arm, with or without pulmonary embolism (PE, or isolated PE. The incidence of CVP-associated VTE was 5.9% (IC95 4.4–7.3% at 3 months, and 11.3% (IC95 9.4–13.2% at 12 months. The incidence of any VTE was 7.6% (IC95 6.0–9.3% at 3 months, and 15.3% (IC95 13.1–17.6% at 12 months. High Khorana risk score and lung cancer were significant predictors of 3 month VTE. In conclusion, this large cohort study of patients with first CVP catheter implantation confirms the high incidence of VTE associated with the CVP implantation and allow identifying high risk patients who may benefit from thromboprophylaxis.

    Ultrasound-guided central venous puncture and fluoroscopic guidance during central venous catheter (CVC) positioning optimizes technical success and lowers the complication rates in children, and is therefore considered standard practice. The purpose of this study was to compare the radiation exposure levels recorded during CVC placement in children weighing less than 10 kg in procedures performed using an image intensifier-based angiographic system (IIDS) to those performed in a flat-panel detector-based interventional suite (FPDS). A retrospective review of 96 image-guided CVC placements, between January 2008 and October 2013, in 49 children weighing less than 10 kg was performed. Mean age was 8.2 ± 4.4 months (range: 1-22 months). Mean weight was 7.1 ± 2.7 kg (range: 2.5-9.8 kg). The procedures were classified into two categories: non-tunneled and tunneled CVC placement. Thirty-five procedures were performed with the IIDS (21 non-tunneled CVC, 14 tunneled CVC); 61 procedures were performed with the FPDS (47 non-tunneled CVC, 14 tunneled CVC). For non-tunneled CVC, mean DAP was 113.5 ± 126.7 cGy cm{sup 2} with the IIDS and 15.9 ± 44.6 cGy . cm{sup 2} with the FPDS (P < 0.001).

    Objective To discuss the use of central venous catheter under the intravenous electrocardiogram (IVECC). Methods 150 adult patients who would undergo selective operation of central venous catheterizations in general anesthesia were randomly divided into three groups, group A, B and C (n =50). Patients in group A received dexter internal jugular vein catheter-ization, patients in group B received dexter subclavian vein catheterization and in group C the dexter subclavian vein punctured and catheterization were performed. IVECC monitoring technology was applied in the three groups. We recorded the data of Lmax, Lact, Lpre and the value of Lmax - Lact and Lpre - Lmax respectively. The anteroposterior position of the X-ray examination after operation was taken to judge whether the catheter was in the right place or not. The standard of over-deep or ectopic for atrium dextrum was Lpre - Lmax ≥0.5 cm. Results 146 patients underwent paracentesis successfully, and 4 patients including one from group A, one from group B and two from group C failed in paracentesis. The average indexes of Lmax - Lact and Lpre - Lact were (2.4 ± 0.3) cm and(2.1 ±0.8)cm respectively in the 146 patients. There were 22 patients with Lpre -Lmax≥0. 5 cm (15.07% ) , including 7 patients in group A, 8 patients in group B and 7 patients in group C. The typical change was catheter tip being located at superior vena cava according to chest X-ray film postoperative. According to the results of IVECG and chest X-ray film, the patients with Lpre -Lmax≥0.5 cm canal were located in atrium dextrum and catheter placement coincidence rate was 100%. Conclusion IVECC assisted central venous catheter is easy to perform, does not have radio-active contamination and can replace X-ray examination.%目的 探讨在心内心电图(IVECG)辅助下置入中心静脉导管的可行性.方法 选择拟在全麻下行择期手术需放置中心静脉导管的成年患者150例,随机分为A、B、C3组,每组50例,

    The implantation of permanent (>14 days) central venous catheters is constantly increasing, accelerated by a trend toward outpatient therapies. Subcutaneous tunneled and non-tunneled catheters as well as port systems are available. The interventional radiologist plays an important role in the implantation of central venous catheters as well as in detection and treatment of any complications. Various access ways via peripheral and central veins are described and the implantation techniques for the different systems explained. The use of peel-away sheaths allows the radiologist to implant subcutaneous tunneled catheters via the Seldinger technique without surgical preparation. Procedure-related early and late complications may occur, and the radiologist plays an important role in the surveillance and management of catheter-associated complications. This review demonstrates the different catheter systems and implantation techniques. (orig.)

    Objective: To investigate the clinical presentation of dislodged totally implantable central venous access system (central venous port-catheter) fragments and the efficacy and safety of percutaneous retrieval of them in our hospital. Materials and methods: Ninety-two cancer patients, mean age of 53.8 years old with 51.1% male, were enrolled from January 2005 to March 2007. They were referred to our catheterization laboratory for retrieval of fractured central venous port-catheter in our hospital. All patients were followed in the outpatient department for at least 1 month after surgical insertion. The characteristics of disrupted central venous port-catheter were recorded. The procedure-related clinical condition was evaluated. Results: The most common presentation of central venous port-catheter dislodgement is irrigation resistance to infusion (51/92). The most common location of fractured fragments is between superior vena cava and right atrium (i.e. proximal end remained in superior vena cava and distal end in right atrium) (22/92). The most common fracture site of the catheter is at the anastomosis between injection port and catheter (77/92). The retrieval set used mostly is loop snare. The success rate of the percutaneous retrieval of dislodged fragment was 97.8% and the complication rate was 3.3% only. Conclusion: The faulty connection between catheter and injection port contributes mainly to dislodgement of central venous port-catheter. Percutaneous retrieval of dislodged catheter is a highly successful, safe and efficient method.

    Peripherally inserted central catheters (PICCs) are widely used in the pediatric population, and their use continues to grow in popularity. These catheters provide a reliable source of venous access to neonatal patients but can also be the cause of life-threatening complications. There are several well-documented complications such as infections, catheter thrombosis, vascular extravasations, and fractured catheters. However, the complication of vascular erosion into the pleural space using both small and silicone-based catheters is rarely described. After obtaining institutional review board approval, we identified 4 cases to review of PICCs complicated by vascular erosions in the past 2 years. Herein, we also review the current literature of PICC complications. Getting the catheter tip as close to the atrial-caval junction as possible and confirmation of this placement are of the utmost importance. The thick wall of the vena cava near the atrium seems to be less likely to perforate; in addition, this position provides increased volume and turbulence to help dilute the hyperosmolar fluid, which seems to also be a factor in this complication. A daily screening chest x-ray in patients with upper extremity PICCs and ongoing parenteral nutrition (PN) are not necessary at this time given the overall low rate of vascular erosion and concerns regarding excessive radiation exposure in pediatric populations. However, a low threshold for chest x-ray imaging in patients with even mild respiratory symptoms in the setting of upper extremity PN is recommended. PMID:25700180

    Full Text Available Introduction: The PICC (peripherally inserted central catheter is a long flexible catheter which is inserted through a peripheral vein, progresses through a needle introducer until the final portion of the vena cava, acquiring characteristics of a central catheter. Objective: To point out the main theoretical and scientific ideas that demonstrate the reliability, competence and ability of nurses to perform the PICC. Methodology: Systematic review of articles, which were found by searching the database scientific journals and bibliographies area. Results: The success of integration depends on the patient assessment and choice of venous access where the catheter will be positioned, and its tip should be in the middle third of the superior vena cava, or the middle third of the inferior vena cava. In neonates, which are used more frequently, proper positioning of the catheter is through nursing care in making the dressing, and the first 24 hours it should be compressive. Ideally, the PICC remains in the vein for periods longer than seven days or until the end of treatment, thus decreasing invasive procedures. Conclusion: According to the Federal Board of Nursing (COFEN, it is lawful for the insertion of PICC nurses, provided it has undergone professional training.

    To evaluate factors which affect the longevity of tunneled central venous catheters (T-CVCs). A retrospective study was conducted on 363 T-CVCs. We evaluated the relevant factors affecting the longevity of the T-CVCs, such as age, gender, indication for catheterization, site of entry vessel, diameter and type of T-CVC, catheter tip position, and underlying diseases. Of the 363 T-CVCs which had been inserted, 331 (91%) were placed through the right internal jugular vein (RIJV). The catheter tip position was the strongest predictor for the longevity of the T-CVC. The short limb of the catheter tip placed either at the cavoatrial junction (CA junction) or below the lower margin of the right main bronchus had a good prognosis. The vessel through which the T-CVC was placed significantly influenced the longevity of the T-CVC; the RIJV was associated with better results than the left internal jugular vein. Also, a split-type catheter was significantly associated with a better result. A two distinct and separate type T-CVC placed through the RIJV in which the short limb catheter tip position was at the level of the CA junction, significantly increased the longevity of T-CVCs.

    To determine the usefulness and safety of radiological placement of a central venous catheter by prospectively comparing the results of interventional radiology and blind surgery. For placement of a central venous catheter, the blind surgical method was used in 78 cases (77 patients), and the interventional radiological method in 56 cases (54 patients). The male to female ratio was 66:68, and the patients' mean age was 48 (range, 18-80) years. A tunneled central venous catheter was used in 74 cases, and a chemoport in 60. We evaluated the success and duration of the procedures, the number of punctures required, and ensuing complications, comparing the results of the two methods. The success rates of the interventional radiological and the blind surgical procedure were 100% and 94.8%, respectively. The duration of central catheterization was 3-395 (mean, 120) day, that of chemoport was 160.9 days, and that of tunneled central venous catheter was 95.1 days. The mean number of punctures of the subclavian vein was 1.2 of interventional radiology, and 2.1 for blind surgery. The mean duration of the interventional radiology and the blind surgical procedure was, respectively, 30 and 40 minutes. The postprocedure complication rate was 27.6% (37 cases). Early complications occurred in nine cases (6.7%): where interventional radiology was used, there was one case of hematoma, and blind surgery gave rise to hematoma (n=2), pneumothorax (n=2), and early deviation of the catheter (n=4). Late complications occurred in 32 cases (23.9%). Interventional radiology involved infection (n=4), venous thrombosis (n=1), catheter displacement (n=2) and catheter obstruction (n=5), while the blind surgical procedure gave rise to infection (n=5), venous thrombosis (n=3), catheter displacement (n=4) and catheter obstruction (n=8). The success rate of interventional radiological placement of a central venous catheter was high and the complication rate was low. In comparison with the blind

    Full Text Available Umbilical venous catheterization is a necessity for the advanced care of very low birth weight neonates. Even with utmost care, few complications cannot be avoided. Fractured and retained catheter fragments are one of them. Endoluminal retrieval of such a catheter is an uncommon and challenging procedure for the interventionist. The only alternative is an open exploration of these patients. Various techniques have been described for retrieval of such foreign bodies. We describe a novel technique for percutaneous retrieval of an embolized umbilical venous catheter from a very low birth weight neonate.

    Full Text Available In a young adult patient having situs solitus with dextrocardia the attempted pulmonary artery catheter placement for emergency mitral valve replacement required an unduly long length (50cm of catheter insertion to get into right ventricle and then into pulmonary artery. Although catheter coiling was suspected initially, chest x-ray taken after successfully placement revealed an uncommon congenital anomalous venous connection i.e. right internal jugular opening into left sided superior vena cava then into inferior vena cava after running all along the left border of the heart. With the result, it required to pass 50cm of PA catheter to get into right ventricle in our patient. This emphasizes the need to look for abnormal venous connections during echocardiography and x-ray screening in congenital heart disease. Fluoroscopy is recommended when an unusual length of pulmonary artery catheter insertion is required to enter the pulmonary artery.

  20. Flushing and Locking of Venous Catheters: Available Evidence and Evidence Deficit

    Directory of Open Access Journals (Sweden)

    Godelieve Alice Goossens

    2015-01-01

    Full Text Available Flushing and locking of intravenous catheters are thought to be essential in the prevention of occlusion. The clinical sign of an occlusion is catheter malfunction and flushing is strongly recommended to ensure a well-functioning catheter. Therefore fluid dynamics, flushing techniques, and sufficient flushing volumes are important matters in adequate flushing in all catheter types. If a catheter is not in use, it is locked. For years, it has been thought that the catheter has to be filled with an anticoagulant to prevent catheter occlusion. Heparin has played a key role in locking venous catheters. However, the high number of risks associated with heparin forces us to look for alternatives. A long time ago, 0.9% sodium chloride was already introduced as locking solution in peripheral cannulas. More recently, a 0.9% sodium chloride lock has also been investigated in other types of catheters. Thrombolytic agents have also been studied as a locking solution because their antithrombotic effect was suggested as superior to heparin. Other catheter lock solutions focus on the anti-infective properties of the locks such as antibiotics and chelating agents. Still, the most effective locking solution will depend on the catheter type and the patient’s condition.

    The technical success and complications were especially focused on and evaluated the need for fixation of a port under fluoroscopic guidance placement of the totally implantable central venous access ports for long term central venous access. Two hundred eighty nine consecutive patients (170 men, 119 women, mean age: 52-year-old) who underwent venous port implantation for the administration of chemotherapy were followed over a 1-month period. The procedures were performed in the angiographic suite by an interventional radiologist and all access was through the right jugular vein, except for the patients who had undergone a right mastectomy. The procedures were performed in the following order: 1) venous puncture, 2) making a pocket, 3) catheter tunneling, 4) port insertion, 5) catheter sizing, and 6) insertion. A port which was connected to the tunneled catheter was inserted into the minimally sized subcutaneous pocket with the aid of a small retractor. A follow-up was performed with medical records and chest radiographs. The follow-up period for evaluating the venous port ranged from 59 to 329 days (mean: 175 days) The procedures performed to gain right jugular vein access were successful without difficulty in all cases. The 18 patients that underwent procedures to gain left jugular vein access encountered some difficulty upon insertion of a catheter into the SVC due to encountering the tortuous left brachiocephalic vein. No complications occurred during and immediately after the procedure. In one case the port chamber rotated within the subcutaneous pocket; however, no catheter migration or malfunction occurred. If port insertion was followed by catheter insertion, the port chamber can be tightly implanted in the minimally sized pocket. This would avoid the need for fixation of the catheter to the port chamber leading into the pocket

Patients received 1% lidocaine (L, buffered 1% lidocaine (LB, or 2% chloroprocaine (CP injected around the internal jugular vein for procedural analgesia for central venous access. Patients reported pain via a standard linear visual analog scale, with 0 representing no pain and 10 being the worst pain imaginable.Results: Overall patient perception of pain was better with CP and L than LB with mean scores of CP 2.4, L 2.6, LB 4.2. Pain with injection mean scores were CP 2.1, L 2.5, LB 3.2. Pain with catheter placement scores were CP 2.5, L 1.7, LB 3.4. Operator assessment of overall pain values were CP 1.9, L 2.2, LB 3.4. LB consistently scored the worst, though compared with CP, this only reached statistical significance in overall patient pain and pain at catheter insertion compared with L.Conclusion: Though chloroprocaine scored better than lidocaine in 3 of 4 parameters, this trend did not achieve statistical significance. Adding sodium bicarbonate to lidocaine isn’t justified in routine practice, nor is routine replacement of lidocaine with chloroprocaine.Keywords: local anesthesia, analgesia, central venous access, lidocaine, chloroprocaine

    Objective: To investigate the main risk factors of peripherally inserted central catheter (PICC) related upper extremity deep venous thrombosis and establish the risk predictive model of PICC-related upper extremity deep venous thrombosis. Methods: Patients with PICC who were hospitalized between January 2014 and July 2015 were studied retrospectively; they were divided into a thrombosis group (n ¼ 52), with patients who had a venous thrombosis complication after PICC, and a no-thrombosis group (n ¼ 144), with patients without venous thrombosis. To compare between the two groups, significantly different variables were selected to perform multivariate logistic regression to establish the risk-predictive model. Results: The PICC catheter history, catheter tip position, and diameter of blood vessel were the key factors for thrombosis. The logistic regression predictive model was as follows:Y ¼ 3.338 þ 2.040 ? PICC catheter history þ1.964? catheter tip position ?1.572? diameter of vessel. The area under the receiver operating characteristic curve for the model was 0.872, 95%CI (0.817e0.927). The cut-off point was 0.801, the sensitivity of the model was 0.832, and the specificity was 0.745. Conclusions: The PICC catheterization history, catheter tip position, the diameter of blood vessel were the key factors for thrombosis. The logistic regression risk model based on these factors is reliable for predicting PICC-related upper extremity deep venous thrombosis.

We analysed the incidence, risk factors, bacteriological profile and antimicrobial susceptibility pattern of the isolates in central venous catheter associated bloodstream infection (CVC-BSI in the intensive care unit (ICU patients and studied the formation of biofilm in CVCs. Materials and Methods: The following case control study included 115 patients with CVC in situ. Quantitative blood cultures (QBC and catheter tip cultures were performed for the diagnoses. Direct catheter staining was done for an early diagnosis by acridine orange (AO and Gram staining methods. Biofilm production in catheters was detected by ′tissue culture plate′ (TCP method. The results were analysed using the computer-based program statistical package for the social sciences (SPSS. Results : In 25/115 patients, definite diagnosis of CVC-BSI was made. The mean age was 48.44 ± 17.34 years (cases vs 40.10 ± 18.24 years (controls and the mean duration of catheterisation was 25.72 ± 8.73 days (cases vs 11.89 ± 6.38 days (controls. Local signs of infection (erythema, tenderness and oozing were found more significantly in CVC-BSI cases. The AO staining was more sensitive and Gram staining of catheters showed higher specificity. Staphylococcus aureus followed by Pseudomonas aeruginosa and non-albicans Candida were common CVC-BSI pathogens. Multidrug-resistant (MDR strains were isolated in bacterial agents of CVC-BSI. Non-albicans Candida and Enterococcus faecalis showed strong biofilm production. Conclusion : The incidence of CVC-BSI was 21.73% and the rate was 14.59 per 1000 catheter days. Prolonged ICU stay and longer catheterisation were major risk factors. S. aureus was isolated most commonly in CVC-BSI cases. The menace of multidrug resistance and

    Full Text Available Totally implantable venous devices (TIVD are increasingly being utilized for venous access for chemotherapy of oncological patients. These devices considerably improve the quality of life of patients requiring long-term chemotherapy. However, despite the great usefulness of TIVDs, their insertion and maintenance is not free of complications. Many early as well as late complications associated with these devices have been reported. We report an unusual, silent, but potentially hazardous complication of catheter fracture and cardiac migration in a 16-year-old girl, in whom the port had been unused for 9 months before presentation. Percutaneous retrieval was unsuccessful as the catheter end was embedded in the myocardium. The catheter was removed via a midline sternotomy without any further complications. We have also reviewed the literature about the possible mechanism of this complication and discussed methods to recognize and avoid it.

    To evaluate the technical feasibility and clinical efficacy of the use of local thrombolysis for below-knee deep vein thrombosis (DVT). From a population of 41 patients with a lower extremity DVT, the prospective clinical trial included 11 patients (7 female, 4 male, average age 61.4 years) treated with catheter-directed thrombolysis with urokinase for below-knee DVT. After removal of the proximal ilofemoral DVT, additional interventional procedures to remove the residual thrombosis and restore the venous flow from the below-knee vein were performed in cases of continuous occlusion of venous flow from the popliteal and tibial veins. Under ultrasound (US) guidance, catheter-directed thrombolysis with urokinase was performed through the ipsilateral popliteal vein. After administration of oral anticoagulation therapy, CT and venography were performed to identify patency and the presence of a recurrent thrombosis. Successful removal of the thrombus and restoration of venous flow were achieved in all of the patients (100%). Restoration of flow with a residual thrombus occurred in one case. Focal venous stenosis was discovered in four cases. The duration of urokinase infusion was 1-4 days (average 2.36 days), which was considered long. For 15.2 months, the venous lumen of all cases was preserved without a recurrent thrombosis. Catheter-directed thrombolysis is an effective procedure for recanalization of below-knee DVT in patients with a lower extremity DVT.

    To analyse the effectiveness of percutaneous treatment of central venous obstruction in patients undergoing hemodialysis. In 100 patients, 107 central venous strictures (56 subclavian (occlusion:21, stenosis:35) and 51 innominate (occlusion:23,stenosis:28)) were assessed, and 170 percutaneous angioplasty procedures were performed. Balloon dilation of the venous lumen was the preferred mode, but if dilation was incomplete we inserted a stent at the site of the stricture. Technical success, procedural complications and the long-term patency rate were evaluated, and the patency difference according to location and degree of stricture, the existence of DM, and any history of central catheter insertion was also determined. We inserted 52 stents in 170 procedures, in 157 (92.4%) of which initial technical success was achieved. Stent migration occurred in two cases and balloon rupture in three. The 6- and 12-month primary patency rates were 46.2% and 24.1%, respectively, and the mean patency rate was 8.5 months. The 1-, 2-and 3-year accumulative patency rates were 59.8%, 47.5% and 35.7%, respectively, and the mean patency rate was 23.5 months. Other than in the history of central catheter insertion, there were no statistically significant differences in patency rates (p=0.0128). In hemodialysis patients with a central venous stricture, percutaneous angioplasty is a safe and useful procedure, but to maintain long-term central venous patency, repeated interventions are required.

    2008-02-01

    Full Text Available Abstract Introduction The insertion of percutaneous central venous catheters is a common procedure in neonatal intensive care nurseries. Placement of the catheter tip in a large central vein is most desirable. Occasionally, due to difficult venous access, catheter tips are left in places that are less than ideal. Case presentation A female infant with a complicated gastroschisis developed signs of short bowel syndrome post surgery. She was treated with a combination of parenteral nutrition and enteral feeds. A central venous line was inserted through a scalp vein. The tip was noted to be in a vessel at the level of the mandible. She subsequently became unwell with large milky pharyngeal aspirates and episodes of bradycardia. Chest radiography revealed aspiration. The central venous line was removed because of presumed extravasation. This is the first reported case of parenteral nutrition extravasation into the pharynx causing aspiration in an infant. Conclusion This complication may have been prevented by recognising that the tip of the catheter was not correctly placed. When catheters are in unusual positions it may be useful to obtain a second radiograph from a different angle or an ultrasound scan to confirm the positioning of the catheter tip.

    Central venous catheters (CVC), used for the management of children with hemato-oncological disorders, are burdened by a significant incidence of mechanical, infective, or thrombotic complications. These complications favor an increasing risk in prolongation of hospitalization, extra costs of care, and sometimes severe life-threatening events. No guidelines for the management of CVC-related occlusion and CVC-related thrombosis are available for children. To this aim, members of the coagulation defects working group and the supportive therapy working group of the Italian Association of Pediatric Hematology and Oncology (AIEOP) reviewed the pediatric and adult literature to propose the first recommendations for the management of CVC-related occlusion and CVC-related thrombosis in children with hemato-oncological disorders.

    Percutaneously inserted central venous catheters (PICCs) have been used to provide central venous access for more than 25 years. Although these lines initially were placed by physicians, currently there are many adult, pediatric, and neonatal nurse-based PICC teams. This article describes the inception and growth of 1 team which, during the last 14 years, has placed more than 3400 catheters and trained more than 50 bedside nurses to insert PICCs. It highlights the development of the team, including details of how team members were selected and trained. Management of ongoing issues was handled by a self-directed nurse team organized into a committee structure composed of an oversight committee and education, guideline, qualifications, and quality improvement subcommittees. This team set and achieved the goals of training bedside nurses to place PICCs, providing consistent management of PICCs, and closely monitoring outcomes. PMID:17536330

    BACKGROUND: Semi-permanent double-lumen central venous catheter as an important supplement of autogenous arteriovenous fistula has been widely used in maintenance hemodialysis patients. But the studies have found that the mortality rate of semi-permanent double-lumen central venous catheters used for hemodialysis vascular access is higher than that of autogenous arteriovenous fistula. The reason is not clear. At present, the effect of different types of vascular access on the micro-inflammatory state is rarely reported. OBJECTIVE: To compare the different levels of inflammation factors in maintenance hemodialysis patients with semi-permanent double-lumen central venous catheter and arteriovenous fistula, and to explore the effect of the hemodialysis vascular access types on the micro-inflammation in maintenance hemodialysis patients. METHODS: Eighty patients with uremia underwent maintenance hemodialysis were selected, and divided into autologous arteriovenous fistula group (n=48) and semi-permanent double-lumen central venous catheter group (n=32) according to different vascular access types. Sixty healthy people were selected as normal control group. The serum high sensitivity C-reactive protein, interleukin-6 and tumor necrosis factor-α of the maintenance hemodialysi group and the normal control group were detected. RESULTS AND CONCLUSION: The serum high sensitivity C-reactive protein, interleukin-6 and tumor necrosis factor-α of the maintenance hemodialysis patients were significantly higher than those of the normal control group (P < 0.01). The serum high sensitivity C-reactive protein, interleukin-6 and tumor necrosis factor-α in the semi-permanent double-lumen central venous catheter group were higher than those in the autologous arteriovenous fistula group (P < 0.05). Micro-inflammatory state exists in maintenance hemodialysis patients, and the utilization of semi-permanent double-lumen central venous catheter as hemodialysis vascular access can

    significativo para la mortalidad en neonatos y niños. CONCLUSIÓN: Se observó en esta revisión que la sepsis primaria fue la complicación más prevalente relacionada al cateter central.OBJECTIVE: To analyze mortality related to infections in the use of central venous catheters in newborns and hospitalized children. METHODS: This was a systematic review, using studies that were identified in the databases of MEDLINE, EMBASE, Lilacs, CINAHL, SciELO and Cochrane, in bibliographical references of articles, and other reviews. Two reviewers independently identified relevant studies, analyzed the methodological quality, and subsequently, extracted data. RESULTS: We encountered 1,000 articles, of which 16 were related to catheter infection and only two mentioned mortality. Findings of these two studies verified that sepsis was the principal complication related to the use of central venous catheters, and the most prevalent microorganisms in these infections were Candida sp. and Enterococcus sp., with significant impact on neonatal and child mortality. CONCLUSION: It was observed in this review that sepsis was most prevalent complication related to central catheters.

METHODS Prospective monitoring was carried out on patients aged over one month whose ICU length of stay was over 24 hours from Jul 2009 to Nov 2010. The risk factors for CRBSI were analyzed. RESULTS Among the 1145 cases surveyed,890 cases were under intravenous catheterization. The rate of intravenous catheterization was 77. 7% while the overall duration was 9189 days. A total of 26 cases of CRBSI were observed with the incidence rate of 2. 9% and the mean daily incidence rate of 2. 8 per 1,000 catheter-day; the incidence rate of CRBSI was positively correlated with the duration of catheterization (x2 =40. 71,P = 0. 000) and frequency of catheterization (x2 =28. 6, P=0. 000), respectively. The duration (OR=2. 415) and frequency (OR=l. 531) of the catheterization were the independent risk factors for CRBSI in general ICU patients with central intravenous catheter. CONCLUSION The incidence rate of CRBSI can be reduced by performing strict hand hygiene procedures, aseptic technique for insertion, care for intravascular catheters and the removal of catheters in a timely manner.

    Full Text Available Central venous catheterization is an invasive procedure commonly preferred for hemodynamic monitorization, total parenteral nutrition, cardiac pacemaker implantation, long-term use of vasoactive or irritating agents and hemodialysis. We present a 19-year-old woman with acute renal failure scheduled for hemodialysis catheterization. A catheter guidewire extending from the right internal jugular vein to the right external iliac vein was detected in the chest X-ray, taken two hours following catheterization after occurrence of arrhythmia and hypotension. Catheteter guidewire was extracted noninvasively without any complications. Most common reasons for this complication are stated to be attention deficits, lack of experience, overtired staff, and inadequate supervision of trainees. In this paper, we discussed this complication’s causes and preventive methods. (Journal of the Turkish Society Intensive Care 2011; 9:64-7

    After the insertion of a central venous catheter, a chest radiograph is usually obtained to ensure correct positioning of the catheter tip. To determine in a paediatric population whether B-mode and colour Doppler sonography after central venous access is useful to evaluate catheter position, thus obviating the need for a postprocedural radiograph. A prospective study of 107 consecutive central venous access procedures placed in a paediatric intensive care unit was performed. At the end of the procedure, B-mode and colour Doppler sonography were used to assess catheter position and check for complications. A postprocedural chest radiograph was obtained in all patients. In 96 patients postprocedural B-mode and colour Doppler sonography showed colour Doppler signals within the vena cava. Among the 11 patients predicted to have a potential complication, there was one pneumothorax and ten malpositions. Chest radiography showed a total of 13 complications - 1 pneumothorax and 12 malpositions. The concordance between colour Doppler sonography and chest radiography was 98.1% in the detection of catheter position; sonography had a sensitivity of 84.6% and a specificity of 100%. The close concordance between B-mode and colour Doppler sonography and chest radiography justifies the more frequent use of sonography to evaluate catheter position because ionizing radiation is eliminated. Chest radiography may then be performed only when there is suspected inappropriate catheter tip position after sonography. (orig.)

    Full Text Available Implantable central venous port catheters are widely used in the management of children with cancer undergoing long term chemotherapy. These catheters can manifest a number of complications such as arrhythmia. Central venous port catheter was placed on a ten years old boy for chemotherapy. Before insertion of port catheter his physical examination, laboratory parameters, electrocardiography and echocardiography were normal. The patient felt palpitations shortly after the insertion of the port catheter. At that time the heart rate was 200 beats/minute but immediately normal sinus rhythm was restored. A chest roentgenogram revealed that the distal fragment of the port catheter was inside the right atrium. The port catheter was pulled back somewhat and then tachycardia attacks stopped. To our knowledge there are a few reports of supraventricular tachycardia (SVT in children associated with central venous port catheter. Here we aimed to present a pediatric case with SVT after placement of central venous port catheter and his management.

No hubo diferencia estadística significante cuanto al tipo de curativo y las variables estudiadas. Los CVC posicionados a 90º en relación a la piel presentaron mayor índice de infección por S. aureus. CONCLUSIÓN: El uso del filme transparente no proporcionó reducción de infección, sin embargo el análisis cualitativo de este tipo de curativo tuvo mejor aceptación por los pacientes y profesionales.OBJECTIVES: To evaluate the efficacy of two types of dressings used on central venous catheter (CVC in patients undergoing hemodialysis and to determine the rate of local and systemic bacterial infection when using gauze and micropore dressings or transparent film dressings. METHODS: This study was a controlled randomized clinical trial with 66 subjects who were equally assigned to two groups (33 subjects per group. Group 1 used gauze and micropore dressings and group 2 used transparent film dressings. Measures consisted of a socio demographic questionnaire, clinical data, and catheter tip and blood culture tests. Subjects remained in the study until removal of the catheter. RESULTS: There were no statistically significant differences regarding the types of dressings. Positioning of CVCs at 90 degrees in relation to the skin had higher rate of infections by S. Aureus. CONCLUSION: Although the use of transparent film dressings did not reduce infection, qualitative data analysis suggested that this type of dressing was preferred by the patients and by the health care providers from a university hospital.

    We performed a meta-analysis for systematic evaluation of the status quo of catheter thrombolysis for the treatment of acute lower limb deep vein thrombosis in China. We searched the China Biomedical bibliographic database (CBM), China National Knowledge Infrastructure (CNKI), Weipu full-text electronic journals, Wanfang full-text database, and Medline (1990 through June 2011) for clinical randomized controlled trials of catheter-directed thrombolysis and superficial venous thrombolysis to compare their efficacies for the treatment of acute deep vein thrombosis. The results were analyzed by using the Cochrane-recommended RevMan 4.2 software package, and the odds ratio (OR) was used as the combined measure of efficacy. The search retrieved 8 randomized controlled trials, and meta-analysis using the total rate of effective treatment as the clinical observation index found that the combined OR for the catheter thrombolysis group versus the superficial venous thrombolysis group was significant (P venous thrombolysis for the treatment of acute deep vein thrombosis in the lower limb in Chinese individuals. However, the included trials were only of medium quality, so more rational and scientific clinical trials are needed to validate this conclusion.

    Objective: To prospectively evaluate the technical success and immediate complication rates of temporary central catheter placement in a homogenous patient population with disorders of hemostasis. Materials and methods: One hundred and thirty three temporary central vein catheters inserted under ultrasound guidance in 119 patients with bleeding disorders were analyzed over a 4-year period. Patients were males (n = 51; 43%) and females (n = 68; 57%) with a mean age of 56.6 years (age range 18-95 years). A catheter was inserted in IJV in 129 (97%) procedures, subclavian vein in 2 (1.5%) procedures and femoral vein in 2 (1,5%) procedures. Thirty-three (24.8%) procedures were performed on bedside. Of 119 patients, 106 (89%) had only one catheter placement and the rest had had more than one catheter placement (range 1-3). Results: Technical success was achieved in all patients (100%). Average number of puncture was 1.01 (range 1-2). One hundred and nineteen insertions (89.5%) were single-wall punctures, whereas 14 insertions were double-wall punctures. Eight (6%) minor complications occurred including oozing of blood around the catheter in five (3.8%) procedures, small hematoma in two (1.5%) procedure and both in one patient. There was no inadvertent arterial puncture or major complications like hemothorax or pneumothorax in any patients. Conclusion: US-guided placement of central vein catheters in patients with disorder of hemostasis is safe with high technical success and low complication rates. US guidance for central venous catheterization should be the preferred method in this group of patients, if available in the hospital setting.

    Heparin locking of venous dialysis catheters is routinely performed in intensive care to maintain catheter patency when the catheters are not being used. Leakage of heparin into the circulation can potentially cause systemic anticoagulation and may present a risk to intensive care patients. To assess the effect of 5000 units per millilitre heparin locking of non-tunnelled dialysis catheters on systemic anticoagulation, we performed a prospective observational study of ten intensive care patients receiving heparin locking of dialysis catheters in an adult tertiary intensive care unit between July and September 2015. Activated partial thromboplastin time (APTT) was measured prior to, and three minutes after, heparin locking of catheter lumens with the manufacturer's recommended locking volume to assess the effect on systemic anticoagulation. Heparin locking of venous dialysis catheters resulted in a significant rise in APTT (P=0.002). The median rise was by 56 seconds (interquartile range 30-166.5). Following heparin locking, 80% of patients had APTT values within or above the range associated with therapeutic anticoagulation. Heparin locking of non-tunnelled venous dialysis catheters can cause systemic anticoagulation in intensive care patients and therefore poses a potential risk to patient safety.

    Neonates with congenital diaphragmatic hernia (CDH) often require placement of lines and tubes for supportive therapy. The resulting altered anatomy can result in diagnostic errors when interpreting the location of support lines and tubes such as UVCs (umbilical venous catheters). The purpose of this study was to evaluate the effect of CDH on UVC position and to evaluate the accuracy at which radiologists describe the position on chest radiographs. During a 5-year period, 406 chest radiographs performed within 7 days of birth in infants with congenital diaphragmatic hernia were identified and reviewed for the following data: presence of UVC, location of catheter tip (cavoatrial junction, intracardiac, intrahepatic or umbilical vein), and location of CDH (right or left). The radiologic report of the UVC tip location for each case was then reviewed individually to determine the adequacy of interpretation. Inadequate reports were classified as incorrect (the wrong location of the catheter tip was reported), no mention (the location of the catheter tip was in a suboptimal location but not mentioned), and not specified (the precise location of the catheter tip was not clearly stated in the report when the tip was in a suboptimal location). A total of 60 infants were identified as having CDH (56 on the left, 4 on the right). The most common location for an incorrectly placed UVC was the contralateral chest, accounting for 26.7% (16/60) of the infants, followed by an abdominal intrahepatic location (16.7%) and the umbilical vein (8.3%). Thirty percent (120/406) of the chest radiograph reports were found to be inadequate regarding the interpretation of the location of the catheter tip. The majority of the inadequate reports (48/406, 11.8%) did not specify when the catheter tip was in a suboptimal location. In 37 reports (9.1%), the location of the catheter tip was reported incorrectly, and no mention of the catheter location was made in 35 reports (8.6%). The location of

    To assess the technical success and complication rates of the radiologic placement of central venous ports via the internal jugular vein. We retrospectively reviewed 1254 central venous ports implanted at our institution between August 2002 and October 2009. All procedures were guided by using ultrasound and fluoroscopy. Catheter maintenance days, technical success rates, peri-procedural, as well as early and late complication rates were evaluated based on the interventional radiologic reports and patient medical records. A total of 433386 catheter maintenance days (mean, 350 days; range 0-1165 days) were recorded. The technical success rate was 99.9% and a total of 61 complications occurred (5%), resulting in a post-procedural complication rate of 0.129 of 1000 catheter days. Among them, peri-procedural complications within 24 hours occurred in five patients (0.4%). There were 56 post-procedural complications including 24 (1.9%, 0.055 of 1000 catheter days) early and 32 (2.6%, 0.074 of 1000 catheter days) late complications including, infection (0.6%, 0.018 of 10000 catheter days), thrombotic malfunction (1.4%, 0.040 of 1000 catheter days), nonthrombotic malfunction (0.9%, 0.025 of 1000 catheter days), venous thrombosis (0.5%, 0.014 of 1000 catheter days), as well as wound problems (1.1%, 0.032 of 1000 catheter days). Thirty six CVPs (3%) were removed due to complications. Bloodstream infections and venous thrombosis were the two main adverse events prolonging hospitalization (mean 13 days and 5 days, respectively). Radiologic placement of a central venous port via the internal jugular vein is safe and efficient as evidenced by its high technical success rate and a very low complication rate.

    Full Text Available Systemic hypotension is common in very low birthweight preterm infants but the nature of the precipitating cause may be unclear. Targeted neonatal echocardiography (TnEcho is being increasingly used to support hemodynamic decisions in the neonatal intensive care unit (NICU, including identifying impairments in the transitional circulation of preterm infants, providing timely re-evaluation after institution of therapies and evaluating the placement of indwelling catheters. We present a case of a preterm infant with systemic hypotension and low cardiac output secondary to a large transatrial shunt induced by a malpositioned umbilical venous catheter. Repositioning of the line led to resolution of the hemodynamic disturbance and clinical instability, highlighting the utility of TnEcho in the NICU.

    Purpose: This study describes several cases of endovascular coil embolization of the proximal internal mammary artery injured by blind approach to the subclavian vein for central venous catheter or pacemaker lead insertion. Materials and methods: We conducted a retrospective analysis of five patients with iatrogenic arterial lesions of the internal mammary artery (IMA). The lesions occurred in three patients from a puncture of the subclavian vein during insertion of a central venous catheter and in two patients from a puncture of the subclavian vein for insertion of a pacemaker lead. Four patients had acute symptoms of bleeding with mediastinal hematoma and hematothorax and one patient was investigated in a chronic stage. A pseudoaneurysm was detected in all five patients. All four acute and hemodynamic unstable patients required hemodynamic support. Results: In all patients, embolization was performed using a coaxial catheter technique, and a long segment of the IMA adjacent distally and proximally to the source of bleeding was occluded with pushable microcoils. In one patient, additional mechanically detachable microcoils were used at the very proximal part of the IMA. Microcoil embolization of the IMA was successful in all patients, and the source of bleeding was eliminated in all patients. Conclusion: Transarterial coil embolization is a feasible and efficient method in treating acute bleeding and pseudoaneurysm of the IMA and should be considered if mediastinal hematoma or hemathorax occurs after blind puncture of the subclavian vein.

    Full Text Available Abstract Critically ill surgical patients are always at increased risk of actual or potentially life-threatening health complications. Central/peripheral venous lines form a key part of their care. We review the current evidence on incidence of central and peripheral venous catheter-related bloodstream infections in critically ill surgical patients, and outline pathways for prevention and intervention. An extensive systematic electronic search was carried out on the relevant databases. Articles were considered suitable for inclusion if they investigated catheter colonisation and catheter-related bloodstream infection. Two independent reviewers engaged in selecting the appropriate articles in line with our protocol retrieved 8 articles published from 1999 to 2011. Outcomes on CVC colonisation and infections were investigated in six studies; four of which were prospective cohort studies, one prospective longitudinal study and one retrospective cohort study. Outcomes relating only to PICCs were reported in one prospective randomised trial. We identified only one study that compared CVC- and PICC-related complications in surgical intensive care units. Although our search protocol may not have yielded an exhaustive list we have identified a key deficiency in the literature, namely a paucity of studies investigating the incidence of CVC- and PICC-related bloodstream infection in exclusively critically ill surgical populations. In summary, the diverse definitions for the diagnosis of central and peripheral venous catheter-related bloodstream infections along with the vastly different sample size and extremely small PICC population size has, predictably, yielded inconsistent findings. Our current understanding is still limited; the studies we have identified do point us towards some tentative understanding that the CVC/PICC performance remains inconclusive.

    Peripherally inserted central catheters (PICC) are used for a variety of infusion therapies. They are indicated in patients requiring long-term venous access. Incorrect positioning of the insertion of a PICC line is one of the known complications when inserting the device in clinical practice. Radiographers once performing imaging will commonly check if the tip of a PICC has entered the superior vena cava. This case study will report on a lesser known incorrect placement of a PICC line into the azygous vein and how this can be detected on radiographic imaging. This outcome for the patient can be detrimental as it has an increased risk of perforation, thrombus, and fistula formation.

    BACKGROUND There is little data comparing catheter-directed thrombolysis (CDT) via small saphenous veins vs. systematic thrombolysis on complications and efficacy in acute deep venous thrombosis patients. The aim of our study was to compare the efficacy and safety of CDT via the small saphenous veins with systematic thrombolysis for patients with acute deep venous thrombosis (DVT). MATERIAL AND METHODS Sixty-six patients with acute DVT admitted from June 2012 to December 2013 were divided into 2 groups: 27 patients received systemic thrombolysis (ST group) and 39 patients received CDT via the small saphenous veins (CDT group). The thrombolysis efficiency, limb circumference differences, and complications such as post-thrombotic syndrome (PTS) in the 2 groups were recorded. RESULTS The angiograms demonstrated that all or part of the fresh thrombus was dissolved. There was a significant difference regarding thrombolysis efficiency between the CDT group and ST group (71.26% vs. 48.26%, P=0.001). In both groups the postoperative limb circumference changes were higher compared to the preoperative values. The differences between postoperative limb circumferences on postoperative days 7 and 14 were significantly higher in the CDT group than in the ST group (all P<0.05). The incidence of postoperative PTS in the CDT group (17.9%) was significantly lower in comparison to the ST group (51.85%) during the follow-up (P=0.007). CONCLUSIONS Catheter-directed thrombolysis via the small saphenous veins is an effective, safe, and feasible approach for treating acute deep venous thrombosis. PMID:27552357

    Full Text Available Abstract Background Totally implantable central venous access devices (intraports are commonly used in cancer patients to administer chemotherapy or parenteral nutrition. Rupture of intraport is a rare complication. Patients and methods During 3 years period, a total of 245 intraports were placed in cancer patients for chemotherapy. Four of these cases (two colon cancer and one each of pancreas and breast cancer had rupture of the intraport catheter, these forms the basis of present report. Results Mean time insitu for intraports was 164∀35 days. Median follow-up time was 290 days and total port time in situ was 40180 days. The incidence of port rupture was 1 per 10,000 port days. Three of the 4 cases were managed by successful removal of catheters. In two of these the catheter was removed under fluoroscopic control using femoral route, while in the third patient the catheter (partial rupture was removed surgically. One of the catheters could not be removed and migrated to right ventricle on manipulations. Conclusion Port catheter rupture is a rare but dreaded complication associated with subcutaneous port catheter device placement for chemotherapy. In case of such an event the patient should be managed by an experienced vascular surgeon and interventional radiologist, as in most cases the ruptured catheter can be retrieved by non operative interventional measures.

    Simon Berzel

    2014-01-01

    Full Text Available This case describes the diagnostic testing and management of an acute thrombosis of the brachial artery in a female neonate. On day seven of life, clinical signs of acutely decreased peripheral perfusion indicated an occlusion of the brachial artery, which was confirmed by high-resolution Doppler ultrasound. Imaging also showed early stages of collateralization so that surgical treatment options could be avoided. Unfractionated heparin was used initially and then replaced by low-molecular-weight heparin while coagulation parameters were monitored closely. Within several days, brachial artery perfusion was completely restored. Acetylsalicylic acid was given for additional six weeks to minimize the risk of recurring thrombosis. If inadequately fixated in a high-risk location, a peripheral venous catheter can damage adjacent structures and thus ultimately cause arterial complications.

    Full Text Available Abstract Thromboembolism is a major cause of death in cancer patients. The association between paraneoplastic hypercoagulability of oncological patients and long-term central venous catheters (CVC may result in CVC associated thrombosis. Patent Foramen Ovale (PFO, especially when associated with atrial septal aneurysm (ASA is a risk factor for paradoxical embolism. We report a case of paradoxical embolism with stroke in an oncological patient with a huge CVC thrombus playing "ping-pong" with an hypermobile ASA with a PFO. We review the management of hypercoagulability in oncologic patients and discuss the potential role of routine transthoracic echocardiography before the implantation of long term central venous catheters to identify predisposing conditions to paradoxical embolism and select patients for anticoagulant therapy.

    Full Text Available Central Venous Catheters (CVC are used in intravenous therapy in order to facilitate diagnosis and treatment. They allow medicine administration, parenteral nutrition and also vascular access in hemodialysis. However, the use of these catheters offers risks of systemic and local infection, including endocarditis and bacteremia. The aim of this study was to isolate microorganisms from CVC utilizing the semiquantitative culture technique, and to identify them through conventional biochemical tests and an automated system. For the study, 198 CVC tips were evaluated and 105 (53% were considered positive, that is, showed microbial growth ³ 15 CFU. The microorganisms found were the following: 63.8% Grampositive bacteria, 30.5% Gram-negative bacteria, and 5.7% yeast. The most isolated were: coagulasenegative Staphylococci (35.2%, Staphylococcus aureus (25.7%, Klebsiella pneumoniae (8.5%, Pseudomonas aeruginosa (7.6%, Acinetobacter baumannii (7.6% and Candida albicans (4.7%. The increase of infection cases related to catheter has been observed worldwide reflecting the increase of invasive medical procedures used to treat patients. This work allowed the identification of the microorganisms most frequently isolated from CVC tips at a teaching hospital in the region of Londrina- PR. The identification of these microorganisms is extremely important in order to optimize the treatment of the infections and to establish methods of prevention.

    Background: Venous thrombosis is a common occurrence in cancer patients, developing spontaneously or in combination with indwelling central venous devices (CVD). Purpose: To analyze the multidetector CT (MDCT) prevalence, appearance, and significance of catheter related thoracic venous thrombosis in oncologic patients and to determine the percentage of thrombi identified in the original reports. Material and Methods: Five hundred consecutive patients were considered. Inclusion criteria were: presence of a CVD; availability of a contrast-enhanced MDCT; and cancer history. Exclusion criteria were: direct tumor compression/infiltration of the veins; poor image quality; device tip not in the scanned volume; and missing clinical data. Seventeen (3.5%) out of the final 481 patients had a diagnosis of venous thrombosis. Results: Factors showing the highest correlation with thrombosis included peripherally-inserted CVD, right brachiocephalic vein tip location, patient performance status 3, metastatic stage disease, ongoing chemotherapy, and longstanding CVD. The highest prevalence was in patients with lymphoma, lung carcinoma, melanoma, and gynecologic malignancies. Eleven out of 17 cases had not been identified in the original report. Conclusion: CVD-related thrombosis is not uncommon in cancer patients and can also be observed in outpatients with a good performance status and a non-metastatic disease. Thrombi can be very tiny. Radiologists should be aware of the possibility to identify (or overlook) small thrombi

  4. Central Venous Disease in Hemodialysis Patients: An Update

    International Nuclear Information System (INIS)

    Central venous occlusive disease (CVD) is a common concern among the hemodialysis patient population, with the potential to cause significant morbidity. Endovascular management of CVD, comprising percutaneous balloon angioplasty and bare-metal stenting, has been established as a safe alternative to open surgical treatment. However, these available treatments have poor long-term patency, requiring close surveillance and multiple repeat interventions. Recently, covered stents have been proposed and their efficacy assessed for the treatment of recalcitrant central venous stenosis and obstruction. Moreover, newly proposed algorithms for the surgical management of CVD warrant consideration. Here, we seek to provide an updated review of the current literature on the various treatment modalities for CVD

    A carbon fibre probe is described which utilises the oxidation of an endogenous biomarker to provide diagnostic information on the condition of intravascular access lines. The probe surface was modified through anodic oxidation to provide a high selectivity towards urate which was used as a redox probe through which the pH could be determined. A Nernstian response (-60 mV/pH) was obtained which was free from the interference of other redox species common to biofluids. The electroanalytical performance of the probe has been optimised and the applicability of the approach demonstrated through testing the responses in whole blood.

  7. Scheme for Creating a Subcutaneous Tunnel to Place an Indwelling Implantable Central Venous Access System in the Forearm

    International Nuclear Information System (INIS)

    We report a method that we have devised in which a secure subcutaneous tunnel is prepared during the placement of an indwelling central venous reservoir in the forearm. Subjects included 69 cases in which a procedure for implanting an indwelling reservoir in the forearm was performed between June 2006 and May 2007. For the subcutaneous tunnel, a 22-G Cathelin needle was advanced from the puncture site, turning toward the subcutaneous pocket side to the deep subcutaneous area. A 14-G Surflo IV catheter was then advanced along the 22-G Cathelin needle from the subcutaneous pocket. With the tip of the 14-G Surflo IV catheter emerging above the skin at the puncture site, the inner needle of the 14-G Surflo IV catheter and the 22-G Cathelin needle were removed. The catheter was passed through the outer 14-G Surflo IV catheter to emerge on the subcutaneous pocket site, then the outer needle of the Surflo catheter was also removed, and a connection to the port was made to create the subcutaneous tunnel. In all 69 cases, the subcutaneous tunnel in the forearm of the nondominant arm was successfully created within a short period of time (100% success rate). No problems were observed due to slack in the catheter until removal of the sutures 1 week later and for 3 months after treatment. With this method, we believe that a subcutaneous tunnel can be prepared in which the contained catheter has minimal freedom of movement, and which minimizes any damage induced by slack in the catheter within the subcutaneous tunnel.

    Circulatory shock is a dangerous medical condition, in which blood flow cannot provide the necessary amount of oxygen to organs and tissues. Currently, its diagnosis and therapy decisions are based on hemodynamic parameters (heart rate, blood pressure, blood gases) and mental status of a patient, which all have low specificity. Measurement of mixed or central venous blood oxygenation via catheters is more reliable, but highly invasive and associated with complications. Our previous studies in healthy volunteers demonstrated that optoacoustic systems provide non-invasive measurement of blood oxygenation in specific vessels, including central veins. Here we report our first results of a clinical study in coronary artery bypass graft (CABG) surgery patients. We used a medical-grade OPO-based optoacoustic system developed in our laboratory to measure in real time blood oxygenation in the internal jugular vein (IJV) of these patients. A clinical ultrasound imaging system (GE Vivid e) was used for IJV localization. Catheters were placed in the IJV as part of routine care and blood samples taken via the catheters were processed with a CO-oximeter. The optoacoustic oxygenation data were compared to the CO-oximeter readings. Good correlation between the noninvasive and invasive measurements was obtained. The results of these studies suggest that the optoacoustic system can provide accurate, noninvasive measurements of central venous oxygenation that can be used for patients with circulatory shock.

    Safe and reliable venous access is mandatory in modern health care, but central venous catheters (CVCs) are associated with significant morbidity and mortality, This paper describes current Swedish guidelines for clinical management of CVCs The guidelines supply updated recommendations that may be useful in other countries as well. Literature retrieval in the Cochrane and Pubmed databases, of papers written in English or Swedish and pertaining to CVC management, was done by members of a task force of the Swedish Society of Anaesthesiology and Intensive Care Medicine. Consensus meetings were held throughout the review process to allow all parts of the guidelines to be embraced by all contributors. All of the content was carefully scored according to criteria by the Oxford Centre for Evidence-Based Medicine. We aimed at producing useful and reliable guidelines on bleeding diathesis, vascular approach, ultrasonic guidance, catheter tip positioning, prevention and management of associated trauma and infection, and specific training and follow-up. A structured patient history focused on bleeding should be taken prior to insertion of a CVCs. The right internal jugular vein should primarily be chosen for insertion of a wide-bore CVC. Catheter tip positioning in the right atrium or lower third of the superior caval vein should be verified for long-term use. Ultrasonic guidance should be used for catheterisation by the internal jugular or femoral veins and may also be used for insertion via the subclavian veins or the veins of the upper limb. The operator inserting a CVC should wear cap, mask, and sterile gown and gloves. For long-term intravenous access, tunnelled CVC or subcutaneous venous ports are preferred. Intravenous position of the catheter tip should be verified by clinical or radiological methods after insertion and before each use. Simulator-assisted training of CVC insertion should precede bedside training in patients. Units inserting and managing CVC should

    Objective To investigate the distribution of pathogenic bacteria group and drug sensitivity in central venous catheter related infections ( CVC-RI ) after heart surgery. Methods The clinical records of 526 patients were screened after open heart surgery and central vein catheterization from Jan. 2009 to June 2011. The clinical materials of CVC-RI patients,and results of bacteria culture and drug sensitivity test were analyzed retrospectively. Results There were 38 patients suffered from CVC-IR and the total occurrence rate was 7. 22% ( 38/526 ). There were 48 stains of pathogenic bacteria cultured, among which there were 26 strains of Gram-positive bacteria ( 54. 16% ), 18 stains of Gram-negative bacteria ( 37. 50% ) and 4 stains of fungus ( 8. 33% ). Common pathogenic bacteria included Staphylococcus aureus ( 29. 16% ),Staphylococcus epidermidis ( 13. 67% ) and Pseudomonas aeruginosa ( 12. 50% ). The analysis on drug sensitivity showed that the sensitivity of Gram-positive bacteria to vancomycin was 100% and followed by chloromycetin,levofoxacin and piperacillin. The drug resistance of Gram-negative bacteria was high with a higher sensitivity to imipenem and followed by levofoxacin,ceftazidime and piperacillin/tazobactam. Conclusion The pathogenic bacteria inducing CVC-IR are commonly Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa after heart surgery,so antibiotics should be chosen reasonably according to drug sensitivity of pathogenic bacteria in anti-infection treatment.%目的 探讨心脏术后中心静脉导管相关性感染(CVC-RI)的致病菌群分布及药敏情况.方法 对我院2009年1月至2011年6月间,进行心脏直视手术并行中心静脉置管术的526例患者临床病历进行筛查,对发生CVC-RI患者的临床资料及细菌培养、药物敏感性试验结果进行回顾性分析.结果 38例患者发生了CVC-RI,总发生率为7.22%(38/526),培养出病原菌48株,其中革兰氏阳性菌有26株(54.16%)

    Full Text Available A 68 year old patient requiring urgent dialysis due to raising potassium was referred to our center. He had 3 indwelling catheters in his heart via right subclavian vein. His left subclavian and interngal jugular veins were thrombosed possibly due to earlier indwelling catheters. The dilemma was if right internal jugular venous route could be used for insertion of dialysis catheter. Under fluoroscopic guidance, right internal jugular vein was cannulated with the dialysis catheter without problems. This case is being presented to highlight the need for imaging both by ultrasound and radiography during the procedure.

    Peripherally inserted central venous catheters (PICCs) are widely used in cancer patients. Although PICC is a convenient tool, its use is associated with an obvious increase in the incidence of venous thrombosis. The risk factors for deep vein thrombosis associated with the use of PICCs in cancer patients are largely unexplored. This study aimed to investigate the incidence of PICC-associated thrombosis in lymphoma compared with its incidences in other types of cancer. A total of 8028 adult cancer patients inserted with PICC between June 2007 and June 2015 were included in this study. A total of 249 of the 8028 included patients (3.1%) inserted with PICC developed upper extremity deep vein thrombosis (PICC-UEDVT). Patients with lymphoma were more likely to have PICC-UEDVT than those with other types of malignancies (7.1% vs. 2.80%; P < 0.001). Logistic analysis revealed that a lymphoma diagnosis was a risk factor for UEDVT in cancer patients inserted with PICC (OR: 3.849, 95% CI: 2.334–6.347). Patients with lymphoma may be more predisposed to developing PICC-UEDVT than those with other types of malignancies. Identifying the mechanism underlying the relationship between PICC-UEDVT and lymphoma requires further study. PMID:27078849

    Full Text Available Introduction: Central venous pressure (CVP measurement is essential in the management of certain clinical situations, including cardiac failure, volume overload and sepsis. CVP measurement requires catheterization of the central vein which is invasive and may lead to complications. The aim of this study was to evaluate the accuracy of measurement of CVP using a new noninvasive method based on near infrared spectroscopy (NIRS in a group of cardiac surgical Intensive Care Unit (ICU patients. Methodology: Thirty patients in cardiac surgical ICU were enrolled in the study who had an in situ central venous catheter (CVC. Sixty measurements were recorded in 1 h for each patient. A total of 1800 values were compared between noninvasive CVP (CVPn obtained from Mespere VENUS 2000 CVP system and invasive CVP (CVPi obtained from CVC. Results: Strong positive correlation was found between CVPi and CVPn (R = 0.9272, P < 0.0001. Linear regression equation - CVPi = 0.5404 + 0.8875 × CVPn (r2 = 0.86, P < 0.001, Bland-Altman bias plots showed mean difference ± standard deviation and limits of agreement: −0.31 ± 1.36 and − 2.99 to + 2.37 (CVPi-CVPn. Conclusion: Noninvasive assessment of the CVP based on NIRS yields readings consistently close to those measured invasively. CVPn may be a clinically useful substitute for CVPi measurements with an advantage of being simple and continuous. It is a promising tool for early management of acute state wherein knowledge of CVP is helpful.

    Purpose: To retrospectively compare immediate and long-term outcome of central venous infusion port inserted via right high versus low jugular vein approaches. Materials and methods: The study included 163 patients (125 women patients, 38 men patients; age range, 18-79 years; mean age, 53 years); 142 patients underwent port insertion with low jugular vein approach and 21 patients with high jugular vein approach. The causes of high jugular vein puncture were metastatic lymphadenopathy (n = 7), operation scar (n = 6), radiation scar (n = 5), failure of low jugular vein puncture (n = 2), and abnormal course of right subclavian artery (n = 1). Medical records and radiologic studies were reviewed retrospectively to determine and compare the outcome and the occurrence of complication related to port. Results: The procedure-related complications were all minor (n = 14, 8.6%) in both groups; hematoma (n = 4, 2.8% in low jugular puncture group and n = 1, 4.8% in high jugular puncture group, p = 0.6295), air embolism (n = 2, 1.4% in low jugular puncture group and n = 0 in high jugular puncture group, p = 0.5842) and minor bleeding (n = 5, 3.5% in low jugular vein puncture group and n = 2, 9.5% in high jugular vein puncture group, p = 0.2054). The average length of follow-up was 431 days for low jugular vein puncture group and 284 days for high jugular vein puncture group. The difference between two groups was significant (p = 0.0349). The reasons for catheter removal were patients' death (59 in low jugular puncture group and 14 in high jugular puncture group, p = 0.0465), suspected infection (11 in low jugular vein puncture group and 2 in high jugular vein puncture group, p = 0.8242), catheter occlusion (four in low jugular vein puncture group and one in high jugular vein puncture group, p = 0.6583). The catheter tip migrated upward an average of 1.86 cm (range, -0.5 to 5.0 cm) in low jugular vein puncture group and 1.56 cm (range, 0-3.6 cm) in high jugular vein

    Purpose: To evaluate the efficacy of percutaneous mechanical thrombectomy (PMT) combined with catheter-directed thrombolysis (CDT) in the treatment of massive symptomatic lower limb deep venous thrombosis (DVT). Materials and methods: One hundred and three clinically confirmed DVT patients were discharged from our institution. Sixteen patients with massive lower limb DVT were included in this retrospective study. After prophylactic placement of inferior vena cava filters (IVCFs), percutaneous mechanical thrombectomy (ATD, n = 10; Straub, n = 6) and catheter-directed thrombolysis were performed in all patients. Complementary therapy included percutaneous transluminal venous angioplasty (PTA, n = 3) and stent placement (n = 1). The doses of thrombolytic agents, length of hospital stay, peri-procedure complications and discharge status were reviewed. Oral anticoagulation was continued for at least 6 months during follow-up. Results: The average hospital stay was 7 days. The technical success rate (complete and partial lysis of clot) was 89%, the other 11% patients only achieved less than 50% clot lysis. The mean dose of urokinase was 3.3 million IU. There were no significant differences of clinical outcome between the ATD and Straub catheter group. The only major complication was an elderly male who experienced a fatal intracranial hemorrhage while still in the hospital (0.97%, 1/103). Minor complications consisted of three instances of subcutaneous bleeding. No transfusions were required. Vascular patency was achieved in 12 limbs during follow-up. No pulmonary emboli occurred. There is one recurrent DVT 4.5 months after the treatment. Conclusions: Percutaneous mechanical thrombectomy combined with catheter-directed thrombolysis is an effective and safe method for the treatment of symptomatic DVT. A randomized prospective study is warranted.

    Full Text Available Establishment of long-term central venous access is a sine qua non step for bone marrow transplantation in children. Most frequently, long-term central venous access has been obtained via blind percutaneous cannulation of subclavian and internal jugular veins or via internal jugular vein cutdown. In order to avoid some potential minor and major complications associated with the subclavian or internal jugular approaches, the authors describe an easy, simple and safe method for central venous access through an external jugular vein cutdown that should be of interest to readers involved in the field of bone marrow transplantation. It should be also considered for children as well as adults needing central venous access via an external catheter - or totally implantable port - for reasons other than bone marrow transplantation, such as total parenteral nutrition and administration of chemotherapeutic agents.O estabelecimento de um acesso venoso central de longa duração é uma condição sine qua non para realizar o transplante de medula óssea em crianças.

Com o objetivo de evitar algumas complicações maiores e menores associadas com a subclávia e a jugular interna, os autores descrevem um método simples, fácil e seguro para o acesso venoso central através de dissecção da veia jugular externa. Este método deveria ser de interesse dos leitores envolvidos com o transplante de medula óssea e ser considerado também para crianças e/ou adultos que necessitem de cateter venoso central de longa permanência (externo ou totalmente implantável devido a outras razões, como a nutrição parenteral ou a administração de agentes quimioterápicos.

    Full Text Available Abstract Background A non-invasive surrogate measurement for central venous oxygen saturation (ScVO2 would be useful in the ED for assessing therapeutic interventions in critically ill patients. We hypothesized that either linear or nonlinear mathematical manipulation of the partial pressure of oxygen in breath at end expiration (EtO2 would accurately predict ScVO2. Methods Prospective observational study of a convenience sample of hemodialysis patients age > 17 years with existing upper extremity central venous catheters were enrolled. Using a portable respiratory device, we collected both tidal breathing and end expiratory oxygen and carbon dioxide concentrations, volume and flow on each patient. Simultaneous ScVO2 measurements were obtained via blood samples collected from the hemodialysis catheter. Two models were used to predict ScVO2: 1 Best-fit multivariate linear regression equation incorporating all respiratory variables; 2 MathCAD to model the decay curve of EtO2 versus expiratory volume using the least squares method to estimate the pO2 that would occur at Results From 21 patients, the correlation between EtO2 and measured ScVO2 yielded R2 = 0.11. The best fit multivariate equation included EtCO2 and EtO2 and when solved for ScVO2, the equation yielded a mean absolute difference from the measured ScVO2 of 8 ± 6% (range -18 to +17%. The predicted ScVO2 value was within 10% of the actual value for 57% of the patients. Modeling of the EtO2 curve did not accurately predict ScVO2 at any lung volume. Conclusion We found no significant correlation between EtO2 and ScVO2. A linear equation incorporating EtCO2 and EtO2 had at best modest predictive accuracy for ScVO2.

    1989-01-01

    Infusion thrombophlebitis is a common troublesome complication of intravenous therapy. This study compared peripheral intravenous Teflon and Vialon catheters. The incidence of phlebitis, bacterial adherence and mechanical resistance (distortion) were assessed on 170 catheters, 85 of each type. The Vialon catheter resulted in less phlebitis than the Teflon one (18 vs. 35; p less than 0.01). During the period 49 to 72 h after the insertion of the catheter, the risk of phlebitis in the Teflon group was twice that in the Vialon group. The study of bacterial adherence using a semi-quantitative culture method demonstrated that 9.0% of the catheters were infected with Staphylococcus epidermidis. There was no statistically significant difference between the two groups (5.7% Vialon group vs. 12.5% Teflon group). The Teflon catheters were much more distorted than vialon catheters: 1.7% vs. 55.7% in the macroscopic study; 1.75% vs. 8.2% in the microscopic study. As Vialon softens at body temperature, it would seem likely that it generates a lesser degree of endothelial injury, explaining the lower rate of phlebitis with Vialon catheters. PMID:2633660

    The Sonic Flashlight is an ultrasound (US) device that projects real-time US images into patients with use of a semireflective/transparent mirror. The present study evaluated the feasibility of use of the Sonic Flashlight for clinical peripherally inserted central catheter placements, originally with the mirror located inside a sterile cover (n = 15), then with the mirror outside (n = 11). Successful access was obtained in all cases. Results show that this new design improved visibility, as judged subjectively firsthand and in photographs. The study demonstrated the feasibility of the Sonic Flashlight and the new design to help assure sterility without degrading visibility, allowing further clinical trials involving physicians and nurses.

    Cerebral venous sinus thrombosis (CVST) can be life threatening. A previously healthy woman in her early forties on oral contraceptives presented with global CVST and rapid clinical deterioration. A novel 'Triaxial Angiojet technique' (KSAW Shuttle [Cook Inc., Bloomington, IN, USA], 5 MAX ACE [Penumbra Inc., Alameda, CA, USA], and Angiojet [Boston Scientific, Marlborough, MA, USA]) was employed to gain access into the superior sagittal sinus. The 5 MAX ACE reperfusion catheter was shortened prior to placing a 4 Fr Angiojet catheter through it. This resulted in markedly improved recanalization with good anterograde flow. The patient was extubated on postoperative day 2 and discharged neurologically intact on postoperative day 10. We report the first case of placing an Angiojet catheter through a larger Penumbra reperfusion catheter when access through a tortuous sigmoid and transverse sinus could not be obtained with a 6 Fr support catheter.

    PurposePercutaneous mechanical thrombectomy (PMT) is now established as an alternative treatment of acute arterial occlusions in addition to fibrinolysis and surgical thrombectomy. The objective of this retrospective study was the investigation of a rotational atherothrombectomy catheter in terms of safety and efficacy in the treatment of acute and subacute femoropopliteal bypass occlusions.Materials and MethodsForty-two patients (average age 65.8 {+-} 9.1 years) with acute (<14 days [n = 31]) and subacute (14-42 days [n = 11]) femoropopliteal bypass occlusions were treated consecutively with a rotational debulking and removal catheter (Straub Rotarex). The average occlusion length was 28.4 {+-} 2.9 (24-34) cm. Thirty-four (81 %) patients underwent venous bypass, and 8 (19 %) patients underwent polytetrafluoroethylene bypass.ResultsThe technical success rate was 97.6 % (41 of 42). In 1 patient, blood flow could not be restored despite the use of the atherothrombectomy system. The average catheter intervention time was 6.9 {+-} 2.1 (4-9) min. Ankle-brachial index increased from 0.39 {+-} 0.13 to 0.83 {+-} 0.11 at discharge and to 0.82 {+-} 0.17 after 1 month (p < 0.05). There were a total of 2 (4.8 %) peri-interventional complications: One patient developed a distal embolism, which was successfully treated with local lysis, and another patient had a small perforation at the distal anastomosis, which was successfully treated with a stent.ConclusionPMT with the Rotarex atherothrombectomy catheter represents a safe and effective option in the treatment of acute and subacute femoropopliteal bypass occlusions because it can quickly restore blood flow.

    Introduction The ESPEN guidelines on long-term (> 3 months) parenteral nutrition recommend the use of tunnelled central venous catheters (CVCs) to minimise the risk of insertion site infection. A developed symptomatic infection of the soft tissue tunnel surrounding a CVC may rapidly become directly life threatening if the infection progresses along the catheter tunnel towards its end inserted into the venous system. This requires immediate management to eliminate infection and limit its effects. Aim To compare two surgical techniques for the treatment of suppurative inflammation of a CVC tunnel: conventional drainage of the infected tissues (surgical technique A) vs. radical en bloc excision of the infected tissues together with the infected central catheter (surgical technique B). Material and methods Seventy-three patients hospitalised due to CVC tunnel phlegmon between April 2004 and May 2014 were included in the retrospective study. Thirty-four (46.5%) patients underwent surgical procedure A and another 39 (53.5%) underwent procedure B. Results The mean duration of antibiotic therapy following procedure A was 8 ±3 days, whereas procedure B required 7 ±2 days of antibiotic therapy (NS). The mean hospitalisation period following procedure B was over 8 days shorter in comparison to that following procedure A (16.54 ±7.59 vs. 24.87 ±10.19, p = 0.009, respectively). Conclusions The surgical treatment of CVC tunnel phlegmon involving radical en bloc excision of suppurated tissues along with the infected CVC shortens hospitalisation, expedites the insertion of a new CVC, and potentially reduces treatment costs.

    A hydrodynamic model is proposed to describe one of the most critical problems in intensive medical care units: the formation of biofilms inside central venous catheters. The incorporation of approximate solutions for the flow-limited diffusion equation leads to the conclusion that biofilms grow on the internal catheter wall due to the counter-stream diffusion of blood through a very thin layer close to the wall. This biological deposition is the first necessary step for the subsequent bacteria colonization.

  9. Direct contrast enhanced Venography MR in the study of central venous accesses in children receiving total parenteral nutrition

    International Nuclear Information System (INIS)

    Purpose. To present direct contrast enhanced Magnetic Resonance Venography, a recently developed method for the study of central venous accesses. Materials and methods. Six patients (4 males and 2 females; age range 15-18 Years) with severe intestinal failure treated with indwelling central Venous catheter since childhood were studied by MR-angiography. The examination was carried out with a 1.5 Philips Gyroscan Intera Magnet, sequences during the simultaneous injection of about 60 ml/limb paramagnetic contrast material, Gd DTPA, diluted with saline solution at a ratio of 1:12. The images were processed with maximum intensity coronal projections and compared with the phlebographic images obtained earlier. Results. In 4 cases the method demonstrated superior vena cava occlusion, in 2 cases inferior vena cava occlusion. The examination was well tolerated by all patients and image quality was very similar to that of the gold standard Study, conventional phlebography. Conclusions. We believe direct contrast-enhanced MR-venography to be a minimally invasive, panoramic and diagnostically reliable method, which should be considered the first choice in the study of central venous accesses of patients receiving total parental nutrition for the medical treatment of intestinal failure. The method does not expose the patients to ionizing radiation or require iodinated contrast material, and is relatively short with a room lime of about 30-40 minutes

  10. The bowed catheter sign: a risk for pericardial tamponade

    The use of a central venous catheter (CVC) has become commonplace in the care of children with a wide variety of medical and surgical problems. Complications resulting from the insertion of these catheters are well recognized and can be life-threatening. When a temporary CVC or other catheter is inserted into the central venous system it is secured to the skin with a combination of sutures and sterile dressing. This fixes the catheter in place and does not allow it to retract, thereby putting pressure on the right atrial wall via the catheter tip if it is too long. The probability of wall penetration is increased if a catheter or device is tapered at the point of contact. The purpose of this case report is to present the bowed catheter sign and to review the anatomy of the cavotricuspid isthmus, a possible predisposing factor to cardiac perforation and tamponade.

    Pediatric emergency physicians, pediatric critical care specialists, and pediatric surgeons perform central venous catheterization in many clinical settings. Complications of the procedure are not uncommon and can be fatal. Despite the frequency of application, the evidence-base describing the surface landmarks involved is missing. The aim of the current study was to critically investigate the surface markings of the central venous system in children. The superior vena cava/right atrial (SVC/RA) junction, superior vena cava (SVC) formation, and brachiocephalic vein (BCV) formation were examined independently by two investigators. Three hundred computed tomography (CT) scans collected across multiple centers were categorized by age group into: 0-3 years, 4-7 years, and 8-11 years. Scans with pathology that distorted or obscured the regional anatomy were excluded. The BCV formation was commonly found behind the ipsilateral medial clavicular head throughout childhood. This contrasts with the variable levels of SVC formation, SVC length, and SVC/RA junction. In the youngest group, SVC formation was most commonly at the second costal cartilage (CC), but moved to the first CC/first intercostal space (ICS) as the child grew. The SVC/RA junction was at the fourth CC in the youngest group and moved to the third CC/third ICS as the child grew. This study demonstrates the variable anatomy of SVC formation and the SVC/RA junction with respect to rib level. This variability underscores the unreliability of surface anatomical landmarks of the SVC/RA junction as a guide to catheter tip position. PMID:26518452

    To assess the outcome of tunneled central venous catheter placement via the right internal jugular vein. Between June 2001 and May 2002, 670 consecutive Hickman catheters were placed in 654 patients via the right internal jugular vein. The procedural complications arising and follow-up data obtained from May to July 2002 were evaluated. The technical success rate for catheter placement was 99.9% (669/670). Procedural complications were limited to eight cases (1.2%), including three pneumothoraces, one early migration of the catheter, one clinically unimportant air embolism, one catheter injury, one catheter kinking and one primary malpositioning in the azygos vein. Catheter dwelling time ranged from 1 to 407 (mean 107.1) days. During the follow-up period, 416 catheter were removed for various reasons: treatment had ended (n=334), patients declined treatment or their drug regimen was changed (n=16), late complications arose (n=53), or other circumstances intervened (n=13). Late complications included 44 cases of catheter-related infection (6.6%), five of catheter migration (0.7%), two of catheter occlusion (0.3%), one of thrombophlebitis (0.15%), and one of catheter-related right atrial thrombosis (0.15%). Only one instance of symptomatic venous thrombosis or stenosis was noted, namely the one case of thrombophlebitis. Because the incidence of subsequent symptomatic venous thrombosis or stenosis is lower, the preferred route for tunneled central venous catheter placement is the right internal jugular vein.

    To evaluate the venous patency in patients treated by catheter-directed thrombolysis with low-dose urokinase (UK) for symptomatic lower extremity deep venous thrombosis (DVT). Eighty-nine consecutive patients (46 women and 43 men; mean age, 58.1 years), treated by catheter-directed thrombolysis with low-dose UK were included in this study. Immediate venous patency was evaluated in terms of technical success (successful restoration of antegrade in-line flow in the treated vein with residual stenosis rate of less than 30%) and clinical success (significant reduction of clinical symptoms before hospital discharge). Late venous patency was evaluated in terms of primary patency rate and clinical success. Immediate technical success was achieved in all patients and immediate clinical success in 80 (90%) patients. There was no major systemic bleeding complication. The primary patency rate at 6 months and 12 months was 84% and 79%, respectively. Fifty-six (63%) patients were asymptomatic after a median clinical follow-up of 18 months, eleven (12%) patients improved moderately, seven (8%) patients remained unchanged, and fifteen (17%) patients had no clinical follow-up. Short-term catheter-directed thrombolysis with low-dose UK can be an effective, safe method to manage DVT of the lower extremities.

    In this retrospective study the success and complication rates after radiologically guided port catheter implantation were evaluated. Between 2000 and 2008, 3,160 port catheter systems were implanted in our interventional suite. All interventions were imaging guided. The puncture of the preferably right internal jugular vein (IJV) was ultrasound-assisted and the catheter tip position was controlled with fluoroscopy. Catheter indwelling time and rates of periprocedural, early and late complications were evaluated. 922,599 catheter days (mean, 292 days; range, 0-2,704 days) were documented. The implantation was successful in 3,153 (99.8%) cases. A total of 374 (11.8%; 0.41/1,000 catheter days) adverse events were recorded. Of these, 42 (1.33%) were periprocedural complications. 86 (3.3%; 0.09/1,000 catheter days) early and 246 (9.4%; 0.27/1,000 catheter days) late onset complications occurred after port implantation. The most common complications were blood stream infection (n = 134; 5.1%; 0.15/1,000 catheter days), catheter-induced venous thrombosis (n = 97; 3.7%; 0.11/1,000 catheter days) and catheter migration (n = 34; 1.3%; 0.04/1,000 catheter days). A total of 193 (6.1%) port explantations were required. Ultrasound guided port implantation via the IJV results in low periprocedural complication rates. (orig.)

    Peripherally inserted central catheters are often positioned blindly in the central circulation, and this may result in high malposition rates, especially in critically ill patients. Recently, a new technology has been introduced (Sherlock 3CG Tip Positioning System) that uses an electro-magnetic system to guide positioning in the superior vena cava, and then intra-cavity ECG to guide positioning at the cavo-atrial junction. In this observational study, we investigated how the Sherlock 3CG Tip Positioning System would affect peripherally inserted central catheter malposition rates, defined using a post-insertion chest radiograph, in critically ill patients. A total of 239 catheters positioned using the Sherlock 3CG Tip Positioning System were analysed. When an adequate position was defined as low superior vena cava or cavo-atrial junction, 134 catheters (56.1%; 95% CI 50-62%) were malpositioned. When an adequate position was defined as mid/low superior vena cava, cavo-atrial junction or high right atrium (≤ 2 cm from cavo-atrial junction), 49 (20.5%; 95% CI 16-26%) catheters were malpositioned. These malposition rates are significantly lower than our own historical data, which used a 'blind' anthropometric technique to guide peripherally inserted central catheter insertion.

    International guidelines advocate the use of first-line ultrasound for central venous catheter, particularly for the internal jugular vein. The role of ultrasound in peripheral venous access remains questionable. In some specific situations, such as pediatrics, obesity and patients with poor venous network, problems to cannulate peripheral vein may occur. Success rate of peripheral intravenous access increases with the diameter of the vein and for a depth of the vein between 0.3 and 1.5 cm. The type of puncture (long-axis or short-axis) and the type of catheters have little influence on the success rate. Specific considerations have to be taken concerning infection control.

    Aim: To determine the agreement and diagnostic accuracy of three-dimensional gadolinium-enhanced magnetic resonance venography (3D-Gd-MRV) in central venous steno-occlusive disease (CVSD) in haemodialysis patients. Materials and methods: Fourteen consecutive haemodialysis patients underwent interventional procedures to evaluate or treat CVSD. 3D-Gd-MRV was performed before the procedures and the results were compared with digital subtraction angiography (DSA). Results: DSA showed >50% stenosis in all 14 patients, 13 of whom were diagnosed correctly using 3D-Gd-MRV. Moderate stenosis was missed at 3D-Gd-MRV in one case whereby the indwelling dialysis central venous catheter may have caused an artefact on the images and hindered the accuracy of the result. The sensitivity of 3D-Gd-MRV in revealing stenosis was 93% (13/14). No complications caused by contrast agent toxicity occurred in any patient. Conclusion: 3D-Gd-MRV employing a non-breath-hold technique is highly sensitive in the diagnosis of CVSD and may be an alternative technique to DSA for the visualization of central veins.

    Full Text Available OBJECTIVE: to develop a risk score for unplanned removal of peripherally inserted central catheter in newborns.METHOD: prospective cohort study conducted in a neonatal intensive care unit with newborn babies who underwent 524 catheter insertions. The clinical characteristics of the newborn, catheter insertion and intravenous therapy were tested as risk factors for the unplanned removal of catheters using bivariate analysis. The risk score was developed using logistic regression. Accuracy was internally validated based on the area under the Receiver Operating Characteristic curve.RESULTS: the risk score was made up of the following risk factors: transient metabolic disorders; previous insertion of catheter; use of a polyurethane double-lumen catheter; infusion of multiple intravenous solutions through a single-lumen catheter; and tip in a noncentral position. Newborns were classified into three categories of risk of unplanned removal: low (0 to 3 points, moderate (4 to 8 points, and high (≥ 9 points. Accuracy was 0.76.CONCLUSION: the adoption of evidence-based preventative strategies based on the classification and risk factors faced by the newborn is recommended to minimize the occurrence of unplanned removals.

    Distal embolization of a fractured indwelling central catheter is a rare complication. The pinch-off syndrome (POS) should be known, prevented and early detected. We present a case in which further radiological exams were required to find the fragmented catheter with an atypical migration, requiring local surgery for removing. After chest and abdominal CT scan, neck X-ray, and heart echography, the catheter was found on the lower limbs X-ray on the internal side of right knee corresponding to a location of saphenous vein. Implanted catheters should be removed after completion of treatment and the integrity of the system should be monitored. To avoid POS, a catheter must be inserted into the subclavian vein as laterally as possible. PMID:27429915

    Upper-extremity deep venous thrombosis is less common than lower-extremity deep venous thrombosis. However, upper-extremity deep venous thrombosis is associated with similar adverse consequences and is becoming more common in patients with complex medical conditions requiring central venous catheters or wires. Although guidelines suggest that this disorder be managed using approaches similar to those for lower-extremity deep venous thrombosis, studies are refining the prognosis and management of upper-extremity deep venous thrombosis. Physicians should be familiar with the diagnostic and treatment considerations for this disease. This review will differentiate between primary and secondary upper-extremity deep venous thromboses; assess the risk factors and clinical sequelae associated with upper-extremity deep venous thrombosis, comparing these with lower-extremity deep venous thrombosis; and describe an approach to treatment and prevention of secondary upper-extremity deep venous thrombosis based on clinical evidence.

    A transhepatic central venous catheter was implanted in a 2-year-old child with a history of multiple venous access procedures and superior and inferior vena cava thrombosis. After 2 weeks, inadvertent dislodgement of the catheter was complicated by a biloma. The biloma was percutaneously drained, but a biliary-venous fistula led to a rapidly progressive and fatal bilhemia. We report this case as an infrequent complication of transhepatic catheterization.

    To assess the CT findings of acute deep venous thrombosis (DVT) in a lower extremity prior to catheter-directed thrombolysis, and to evaluate their relevance to the patency of an iliac venous stent placed with the help of CT after catheter-directed thrombolysis of DVT. Fourteen patients [M:F=3:11; age, 33-68 (mean, 50.1) years] with acute symptomatic DVD of a lower extremity underwent CT before and after catheter-directed thrombolysis using an iliac venous stent. The mean duration of clinical symptoms was 5.0 (range, 1-14 days. The CT findings prior to thrombolysis were evaluated in terms of their anatomic cause and the extent of the thrombus, and in all patients, the patency of the iliac venous stent was assessed at CT performed during a follow-up period lasting 6-31 (mean, 18.9) months. All patients were assigned to the patent stent group (n=9) or the occluded stent group (n=5). In the former, the anatomic cause of patency included typical iliac vein compression (May-Thurner syndrome) (n=9), and a relatively short segmental thrombus occurring between the common iliac and the popliteal vein (n=8). Thrombi occurred in the iliac vein (n=3), between the common iliac and the femoral vein (n=3), and between the common iliac and the popliteal vein (n=2). In one case, a relatively long segmental thrombus occurred between the common iliac vein and the calf vein. In the occluded stent group, anatomic causes included atypical iliac vein compression (n=3) and a relatively long segmental thrombus between the common iliac and the calf vein (n=4). Typical iliac vein compression (May-Thurner syndrome) occurred in two cases, and a relatively short segmental thrombus between the external iliac and the common femoral vein in one. Factors which can affect the patency of an iliac venous stent positioned after catheter-directed thrombolysis are the anatomic cause of the stenosis, and the extent of a thrombus revealed at CT of acute DVT and occurring in a lower extremity prior to

    We wanted to evaluate the feasibility of catheter-directed thrombolysis with a continuous infusion of low-dose urokinase for treating non-acute (less than 14 days) deep venous thrombosis of the lower extremity. The clinical data of 110 patients who were treated by catheter-directed thrombolysis with a continuous infusion of low-dose urokinase for lower extremity deep venous thrombosis was analysed. Adjunctive angioplasty or/and stenting was performed for the residual stenosis. Venous recanalization was graded by pre- and posttreatment venography. Follow-up was performed by clinical evaluation and Doppler ultrasound. A total of 112 limbs with deep venous thrombosis with a mean symptom duration of 22.7 days (range: 15-38 days) were treated with a urokinase infusion (mean: 3.5 million IU) for a mean of 196 hours. After thrombolysis, stent placement was performed in 25 iliac vein lesions and percutaneous angioplasty (PTA) alone was done in fi ve iliac veins. Clinically significant recanalization was achieved in 81% (90 of 112) of the treated limbs: complete recanalization was achieved in 28% (31 of 112) and partial recanalization was achieved in 53% (59 of 112). Minor bleeding occurred in 14 (13%) patients, but none of the patients suffered from major bleeding or symptomatic pulmonary embolism. During followup (mean: 15.2 months, range: 3-24 months), the veins were patent in 74 (67%) limbs. Thirty seven limbs (32%) showed progression of the stenosis with luminal narrowing more than 50%, including three with rethrombosis, while one revealed an asymptomatic iliac vein occlusion: 25 limbs (22%) developed mild post-thrombotic syndrome, and none had severe post-thrombotic syndrome. Valvular reflux occurred in 24 (21%) limbs. Catheter-directed thrombolysis with a continuous infusion of low-dose urokinase combined with adjunctive iliac vein stenting is safe and effective for removal of the clot burden and for restoration of the venous flow in patients with non-acute lower

    AIM: To investigate the effect of low central venous pressure (LCVP) on blood loss during hepatectomy for hepatocellular carcinoma (HCC).METHODS: By the method of sealed envelope,50 HCC patients were randomized into LCVP group (n = 25) and control group (n = 25). In LCVP group,CVP was maintained at 2-4 mmHg and systolic blood pressure (SBP) above 90 mmHg by manipulation of the patient's posture and administration of drugs during hepatectomy, while in control group hepatectomy was performed routinely without lowering CVP. The patients'preoperative conditions, volume of blood loss during hepatectomy, volume of blood transfusion, length of hospital stay, changes in hepatic and renal functions were compared between the two groups.RESULTS: There were no significant differences in patients' preoperative conditions, maximal tumor dimension, pattern of hepatectomy, duration of vascular occlusion, operationtime, weight of resected liver tissues, incidence of post-operative complications, hepatic and renal functions between the two groups. LCVP group had a markedly lower volume of total intraoperative blood loss and blood loss during hepatectomy than the control group, being 903.9±180.8 mL vs 2 329.4±2 538.4(W=495.5, P<0.01) and 672.4±429.9 mL vs1 662.6± 1932.1 (W=543.5, P<0.01). There were no remarkable differences in the pre-resection and post-resection blood losses between the two groups. The length of hospital stay was significantly shortened in LCVP group as compared with the control group, being 16.3±6.8 d vs21.5 ± 8.6 d (W= 532.5, P<0.05).CONCLUSION: LCVP is easily achievable in technique.Maintenance of CVP≤4 mmHg can help reduce blood loss during hepatectomy, shorten the length of hospital stay, and has no detrimental effects on hepatic or renal function.

    Ten intensive care patients and five healthy volunteers each received a bolus injection of lidocaine HCl (100 mg, 2%) over an injection period of 5 s. After 0.5, 1, 2, 4, 8, 15 and 25 min arterial, central venous and peripheral venous blood samples were collected. In four of the volunteers, arterial and central venous samples were also taken about 10 s after the end of injection. The fluorescence polarization method by means of the Abbott-TDx system was used, and plasma concentrations of lidocaine were determined. The measurements showed that lidocaine levels in central venous plasma 10 s after the end of administration were higher than those in arterial plasma. By 30 s after administration the opposite situation had developed, so that arterial concentrations were higher than those in central venous plasma. This relation did not change throughout the study, though the two levels became closer, as is shown by the ratios (Table 3, Fig. 2). Concentrations in peripheral venous plasma increased more slowly but remained far below those in arterial and central venous plasma, at least for the first 8 min. After 15 min lidocaine levels were almost the same in all three samples. During the entire study there were no ECG changes, and neither heart rate nor blood pressure showed any significant deviation from the values obtained at the beginning. The volunteers had minor toxic manifestations, such as dizziness, tinnitus and a metallic taste in the mouth; one person had a sensation of pressure in his chest, which improved following oxygen administration.(ABSTRACT TRUNCATED AT 250 WORDS)

    To evaluate the results and complications of placement of implantable port according to approach routes and methods. Between April 2001 and October 2002, a total of 103 implantable chemoport was placed in 95 patients for chemotherapy using preconnected type (n=39) and attachable type (n=64). Puncture sites were left subclavian vein (n=35), right subclavian vein (n=5), left internal jugular vein (n=9), right internal jugular vein (n=54). We evaluated duration of catheterization days, complications according to approach routes and methods. Implantable chemoport was placed successfully in all cases. Duration of catheterization ranged from 8 to 554 days(mean 159, total 17,872 catheter days). Procedure related complications occurred transient pulmonary air embolism (n=1), small hematoma (n=1) and malposition in using preconnected type (n=2). Late complications occurred catheter migration (n=5), catheter malfunction (n=3), occlusion (n=1) and infection (n=11). Among them 15 chemoport was removed (14.5%). Catheter migration was occured via subclavian vein in all cases (13%, p=.008). Infection developed in 10.7% of patients(0.61 per 1000 catheter days). There were no catheter-related central vein thrombosis. Implantation of chemoport is a safe procedure. Choice of right internal jugular vein than subclavian vain vein for puncture site has less complications. And selection of attachable type of chemoport is convenient than preconnected type. Adequate care of chemoport is essential for long patency.

    Full Text Available Venous malformations are rare but possible findings too, constituting a further risk factor for central venous catheter procedures. Herein we describe a case of death because of an innominate vein perforation by a catheter that incidentally was tucked into a sacciform malformation. Even if the technology advancement is constantly offering us new investigation tools, up to now diagnostic options are limited in the detection of those malformations that could potentially lead to dramatic complications as the described one. The present work raises the awareness about rare venous anomalies and their potential clinical implications. A proper literature review and diagnostic implementation proposal are reported.

    Optimising perioperative haemodynamic status may reduce postoperative complications. In this prospective prevalence study, we investigated the associations between standard haemodynamic parameters and a low central venous oxygen saturation (ScvO2) in patients after major surgery. A total of 201 patients requiring continuous arterial and central venous pressure monitoring after major surgery were recruited. Simultaneous arterial and central venous blood gases, haemodynamic and biochemical data and perfusion index were obtained from patients at a single time-point within 24 hours of surgery. A low ScvO2 (ventilation, mean arterial pressure, central venous pressure, haemoglobin concentrations, arterial pH and lactate concentrations, arterial oxygen (PaO2) and carbon dioxide tensions (PaCO2) were all associated with a low ScvO2 in the univariate analyses. In the multivariate analysis, only a higher perfusion index (odds ratio [OR] 0.87, 95% confidence interval [CI] 0.78 to 0.98), PaO2 (OR 0.98 per mmHg increment, 95% CI 0.97 to 0.99) and PaCO2 (OR 0.88 per mmHg increment, 95% CI 0.82 to 0.95) and a lower central venous pressure (OR 1.14 per mmHg increment, 95% CI 1.04 to 1.25) were significantly associated with a reduced risk of a low ScvO2, all in a linear fashion. In conclusion, PaO2, PaCO2, perfusion index and central venous pressure were significant predictors of a low ScvO2 in patients after major surgery including cardiac surgery. PMID:25579290

    One of the recognised complications of catheter ablation is pulmonary venous stenosis. The aim of this study was to compare two methods of evaluation of pulmonary venous diameter for follow-up assessment of the above complication: (1) a linear approach evaluating two main diameters of the vein, (2) semiautomatically measured cross-sectional area (CSA). The study population consists of 29 patients. All subjects underwent contrast-enhanced magnetic resonance angiography (CeMRA) of the pulmonary veins (PVs) before and after the ablation; 14 patients were also scanned 3 months later. PV diameter was evaluated from two-dimensional multiplanar reconstructions by measuring either the linear diameter or CSA. A comparison between pulmonary venous CSA and linear measurements revealed a systematic difference in absolute values. This difference was not significant when comparing the relative change CSA and quadratic approximation using linear extents (linear approach). However, a trend towards over-estimation of calibre reduction was documented for the linear approach. Using CSA assessment, significant PV stenosis was found in ten PVs (8%) shortly after ablation. Less significant PV stenosis, ranging from 20 to 50% was documented in other 18 PVs (15%). CeMRA with CSA assessment of the PVs is suitable method for evaluation of PV diameters. (orig.)

    Full Text Available Background. Central venous catheters and peripherally inserted central catheters are well established risk factors for upper limb deep vein thrombosis. There is limited literature on the thrombosis rates in patients with peripheral catheters. A prospective observational study was conducted to determine the incidence of peripheral catheter-related thrombosis in surgical patients. Methods. Patients deemed high risk for venous thrombosis with a peripheral catheter were considered eligible for the study. An ultrasound was performed on enrolment into the study and at discharge from hospital. Participants were reviewed twice a day for clinical features of upper limb deep vein thrombosis during their admission and followed up at 30 days. Results. 54 patients were included in the study. The incidence of deep vein thrombosis and superficial venous thrombosis was 1.8% and 9.2%, respectively. All cases of venous thrombosis were asymptomatic. Risk factor analysis was limited by the low incidence of thrombosis. Conclusion. This study revealed a low incidence of deep vein thrombosis in surgical patients with peripheral catheters (1.8%. The study was underpowered; therefore the association between peripheral catheters and thrombosis is unable to be established. Future studies with larger sample sizes are required to determine the association between peripheral catheters and thrombosis.

    Lower extremity deep venous thrombosis (DVT) is uncommon in the pediatric population, but it can be associated with severe symptoms and potential long-term morbidity secondary to post-thrombotic syndrome. Inferior vena cava (IVC) atresia can predispose a patient to the development of extremity DVT. There is no clear consensus on optimal management of extensive extremity DVT in pediatric patients, especially in patients with IVC anomalies. We report a case of iliofemoral DVT in a 9-year-old boy with IVC atresia and presumed protein S deficiency that was treated successfully using pharmacomechanical thrombectomy and catheter-directed thrombolysis. He was maintained on long-term anticoagulation and remained symptom free at 6 months' follow-up.

    Peripherally inserted central catheter (PICC) has been widely used to treat cancer patients. It is unknown whether or not it can be applied safely during radiotherapy. The study aimed to investigate the direct effects of gamma radiation on physical properties of PICC. A total of 60 catheters were included in this study. Thirty PICCs were exposed to a radiation field, and another 30 PICCs received radiation in a 3-cm homogeneity water equivalent phantom and then were irradiated. Each group was divided into three subgroups: 10 PICCs were given conventional fractionation, 2 Gy per fraction, 5 fractions per week; 10 PICCs were continuously given hypofractionation, 10 Gy per fraction, for 6 weeks; and 10 PICCs were given mock radiation as controls. The physical properties of these catheters were analyzed after radiation. None of the PICCs leaked under 300-kPa airflow pressure lasting 15 seconds. Fracture force values and liquid velocity values of all PICCs were within the normal range. The liquid velocity values of the control groups were higher than the two groups that received radiation (P 0.05). There were no statistical differences among the conventional fractionation group, hypofractionation group, and control group when compared to the fracture force values in two parts (P > 0.05). The physical property of PICC is quite stable with a clinically relevant dose of gamma radiation. It is likely that PICC can be used safely in patients receiving radiotherapy, although further in vivo and clinical studies are required. PMID:27611595

    Purpose: To evaluate the efficacy and outcome of a flow confirmation study (FCS) in oncologic outpatients undergoing chemotherapy suspected of a central venous port (CVP) system-related mechanical complication. Materials and methods: A total of 66 patients (27 men, 39 women; mean age, 60 years) received FCS for the following reasons: prolonged infusion time during chemotherapy (n = 32), inability to inject saline fluid (n = 15), lateral neck and/or back pain (n = 6), subcutaneous extravasation of anticancer drug (n = 5), arm swelling (n = 4), and inability to puncture the port (n = 4). FCS consisted of examining the position of CVP, potential secondary shifts or fractures, and integrity of the system using contrast material through the port. Results: Of the 66 patients, 43 had an abnormal finding uncovered by FCS. The most frequent abnormal findings was catheter kinking (n = 22). Explantation and reimplantation of the CVP system was required in 21 of the 66 patients. Remaining 45 patients were able continue using the CVP system after the FCS without any system malfunction. Conclusion: FCS was effective for evaluating CVP system-related mechanical complications and was useful for deciding whether CVP system explantation and reimplantation was required.

    To evaluate visualization of the right adrenal vein (RAV) with multidetector CT and non-contrast-enhanced MR imaging in patients with primary aldosteronism. A total of 125 patients (67 men) scheduled for adrenal venous sampling (AVS) were included. Dynamic 64-detector-row CT and balanced steady-state free precession-based non-contrast-enhanced 3-T MR imaging were performed. RAV visualization based on a four-point score was documented. Both anatomical location and variation on cross-sectional imaging were evaluated, and the findings were compared with catheter venography as the gold standard. The RAV was visualized in 93.2 % by CT and 84.8 % by MR imaging (p = 0.02). Positive predictive values of RAV visualization were 100 % for CT and 95.2 % for MR imaging. Imaging score was significantly higher in CT than MR imaging (p < 0.01). The RAV formed a common trunk with an accessory hepatic vein in 16 % of patients. The RAV orifice level on cross-sectional imaging was concordant with catheter venography within the range of 1/3 vertebral height in >70 % of subjects. Success rate of AVS was 99.2 %. Dynamic CT is a reliable way to map the RAV prior to AVS. Non-contrast-enhanced MR imaging is an alternative when there is a risk of complication from contrast media or radiation exposure. (orig.)

    Introduction. Central venous catheters (CVC) have been inserted percutaneously since 1989. This technique has been adapted for transhepatic insertion of large-bore catheters in children with occluded central veins. Materials and methods. Three children aged 5, 11, and 12 years required hemodialysis or plasmaphoresis for treatment of life-threatening conditions. All central veins were occluded, thus transhepatic insertion of a large-bore catheter was necessary. All children underwent successful placement using a combination of ultrasound guidance and fluoroscopy. No complications occurred. Discussion. Transhepatic insertion of large-bore catheters can be performed safely in children. Catheter removal should be accompanied by track embolization to prevent exsanguinating hemorrhage. Conclusion. Transhepatic insertion of dialysis catheters is a safe alternative in children with occluded central veins. (orig.) With 2 figs., 7 refs.

    Burned patients with deep venous thrombosis present a particularly perplexing challenge. They frequently require central venous catheters. Their altered skin integrity does not permit correlation with the typical changes described by the classic terminology for thrombophlebitis or its most severe forms, phlegmasia cerulea dolens or phlegmasia alba dolens. They are at risk of exsanguination or massive graft loss with lytic therapy or anticoagulation. Venous thrombectomy may be a necessary limb-saving surgical option.

    To retrospectively analyze the technical result and long term outcome of central venous arm ports placed by radiologists. Over a 5-year period, 399 arm ports were implanted by radiologists in 391 patients. The system consists of a low profile titanium chamber and a silicone catheter. Ports were placed at the forearm after puncture of a vein proximally to the elbow under fluoroscopic guidance. In a retrospective analysis the technical results and the long term outcome were evaluated. Complications were documented according to the standards of the society of interventional radiology. In 391 patients a total of 98 633 catheter days were documented (1 - 1325 days, mean 252 days). Primary technical success was 99.25 % (396 / 399) with a 100 % secondary technical success rate. No severe procedural complications, e. g. pneumothorax or severe hemorrhage, were found. A total of 45 complications occurred (11.28 %, 0.45 / 1000 catheter days), including 8 portal pocket infections (27 - 205 days, mean 115 days). Fifteen ports were explanted because of complications. The complication rate corresponds to the data from subclavian ports and is less than the complication rates published in large surgical trials. Implantation of central-venous arm ports by radiologists is safe and minimally invasive. No severe immediate procedural complications occur due to the peripheral implantation site. Long term complication rates are comparable to other studies of radiological or surgical port implantation at different sites. (orig.)

    Full Text Available OBJECTIVE: to relate the variables from a surveillance form for intravenous devices in high risk newborn infants with peripherally inserted central catheter related infection.METHODOLOGY: approximately 15 variables were studied, being associated with peripherally inserted central catheter related infection, this being defined by blood culture results. The variables analyzed were obtained from the surveillance forms used with intravenous devices, attached to the medical records of newborn infants weighing between 500 and 1,499 g. The statistical association was defined using the Chi-squared and Student t tests. The study was approved by the Research Ethics Committee of the Instituto Fernandes Figueira under process N. 140.703/12.RESULTS: 63 medical records were analyzed. The infection rate observed was 25.4%. Of the variables analyzed, only three had a statistically-significant relationship with the blood culture - the use of drugs capable of inhibiting acid secretion, post-natal steroid use, and undertaking more than one invasive procedure (p-value of 0.0141, 0.0472 and 0.0277, respectively.CONCLUSION: the absence of significance of the variables of the form may be related to the quality of the records and to the absence of standardization. It is recommended that the teams be encouraged to adhere to the protocol and fill out the form.

    Full Text Available This prospective study was carried out over a period of 6 months in the Paediatric Intensive Care Unit (PICU of a tertiary care teaching hospital. The aim of the study was to determine the organisms causing catheter related nosocomial infections in the PICU and to study their antimicrobial susceptibility pattern. Patients with endotracheal intubation, indwelling urinary catheters and central venous catheters (CVC/venous cutdown catheters were included in the study. Colonization of the endotracheal tube, urinary catheter related infections (UCRI and colonization of the CVC/venous cutdown catheters was studied. E. coli was the commonest organism colonizing the endotracheal tube tip with maximum susceptibility to cefotaxime and amikacin. E. coli was also was the commonest organism causing UCRI with maximum susceptibility to nitrofurantoin and amikacin. Acinetobacter was the commonest organism colonizing the CVC/venous cutdown catheters with maximum susceptibility to ciprofloxacin. All these sites of catheter related infections considered together, E. coli and Klebsiella were the commonest nosocomial organisms. Both had maximum susceptibility to amikacin. Methicillin resistant Staphylococcus aureus (MRSA was isolated only from one culture. All the organisms had a poor susceptibility to cefazolin and amoxycillin. A knowledge of the resident microbial flora and their antimicrobial susceptibility pattern is necessary for formulating a rational antibiotic policy in an ICU.

  18. Rhodococcus bacteremia in cancer patients is mostly catheter related and associated with biofilm formation.

    Directory of Open Access Journals (Sweden)

    Fadi Al Akhrass

    Full Text Available Rhodococcus is an emerging cause of opportunistic infection in immunocompromised patients, most commonly causing cavitary pneumonia. It has rarely been reported as a cause of isolated bacteremia. However, the relationship between bacteremia and central venous catheter is unknown. Between 2002 and 2010, the characteristics and outcomes of seventeen cancer patients with Rhodococcus bacteremia and indwelling central venous catheters were evaluated. Rhodococcus bacteremias were for the most part (94% central line-associated bloodstream infection (CLABSI. Most of the bacteremia isolates were Rhodococcus equi (82%. Rhodococcus isolates formed heavy microbial biofilm on the surface of polyurethane catheters, which was reduced completely or partially by antimicrobial lock solution. All CLABSI patients had successful response to catheter removal and antimicrobial therapy. Rhodococcus species should be added to the list of biofilm forming organisms in immunocompromised hosts and most of the Rhodococcus bacteremias in cancer patients are central line associated.

    2001-05-01

    A postal questionnaire was sent to all UK consultant members of the Neuroanaesthesia Society to ascertain whether there was any consensus on indications for use and route of insertion of central venous cannulae in elective neuroanaesthetic practice. Five brief clinical scenarios were presented. Of 179 respondents, 98% indicated that they would insert a central venous cannula into patients requiring excision of an acoustic neuroma in the sitting position, 76% for clipping of an intracranial aneurysm and 75% for resection of an arteriovenous malformation. The antecubital fossa was the preferred route of insertion for 43.5% of respondents with 36.5% preferring the internal jugular approach. The subclavian (17%) and femoral (3%) routes were unpopular first-choice approaches. A significant proportion of respondents (43.5%) do not routinely order a chest X-ray at any stage following pre-operative central venous cannulation. The indications for use and advantages and disadvantages of each route of insertion, with reference to neuro-anaesthetic practice, are discussed. PMID:11350335

    Circulatory shock may be fatal unless promptly recognized and treated. The most commonly used indicators of shock (hypotension and tachycardia) lack sensitivity and specificity. In the initial stages of shock, the body compensates by reducing blood flow to the peripheral (skin, muscle, etc.) circulation in order to preserve vital organ (brain, heart, liver) perfusion. Characteristically, this can be observed by a greater reduction in peripheral venous oxygenation (for instance, the axillary vein) compared to central venous oxygenation (the internal jugular vein). While invasive measurements of oxygenation are accurate, they lack practicality and are not without complications. We have developed a novel optoacoustic system that noninvasively determines oxygenation in specific veins. In order to test this application, we used lower body negative pressure (LBNP) system, which simulates hemorrhage by exerting a variable amount of suction on the lower body, thereby reducing the volume of blood available for central circulation. Restoration of normal blood flow occurs promptly upon cessation of LBNP. Using two optoacoustic probes, guided by ultrasound imaging, we simultaneously monitored oxygenation in the axillary and internal jugular veins (IJV). LBNP began at -20 mmHg, thereafter was reduced in a step-wise fashion (up to 30 min). The optoacoustically measured axillary oxygenation decreased with LBNP, whereas IJV oxygenation remained relatively constant. These results indicate that our optoacoustic system may provide safe and rapid measurement of peripheral and central venous oxygenation and diagnosis of shock with high specificity and sensitivity.

  1. Use of PTFE Stent Grafts for Hemodialysis-related Central Venous Occlusions: Intermediate-Term Results

    International Nuclear Information System (INIS)

    Purpose: To assess the safety and effectiveness of a polytetrafluoroethylene (PTFE) encapsulated nitinol stents (Bard Peripheral Vascular, Tempe, AZ) for treatment of hemodialysis-related central venous occlusions. Materials and Methods: Study design was a single-center nonrandomized retrospective cohort of patients from May 2004 to August 2009 for a total of 64 months. There were 14 patients (mean age 60 years, range 50–83 years; 13 male, 1 female). All patients had autogenous fistulas. All 14 patients had central venous occlusions and presented with clinical symptoms of the following: extremity swelling (14%, 2 of 14), extremity and face swelling (72%, 10 of 14), and face swelling/edema (14%, 2 of 14). There was evidence of access dysfunction with decreased access flow in 36% (5 of 14) patients. There were prior interventions or previous line placement at the site of the central venous lesion in all 14 patients. Results were assessed by recurrence of clinical symptoms and function of the access circuit (National Kidney Foundation recommended criteria). Results: Sixteen consecutive straight stent grafts were implanted in 14 patients. Average treated lesion length was 5.0 cm (range, 0.9–7 cm). All 14 patients had complete central venous occlusion (100% stenosis). The central venous occlusions were located as follows: right subclavian and brachiocephalic vein (21%, 3 of 14), right brachiocephalic vein (36%, 5 of 14), left brachiocephalic vein (36%, 5 of 14), and bilateral brachiocephalic vein (7%, 1 of 14). A total of 16 PTFE stent grafts were placed. Ten- or 12-mm-diameter PTFE stent grafts were placed. The average stent length was 6.1 cm (range, 4–8 cm). Technical (deployment), anatomic (<30% residual stenosis), clinical (resolution of symptoms), and hemodynamic (resolution of access dysfunction) success were 100%. At 3, 6, and 9 months, primary patency of the treated area and access circuit were 100% (14 of 14). Conclusions: This PTFE encapsulated stent

    STUDY OBJECTIVE: To determine the analgesic efficacy of three different rates of remifentanil infusion in patients undergoing insertion or removal of long-term central venous access devices during monitored anesthesia care and local anesthetic field infiltration. DESIGN: Double-blinded, randomized, controlled study. SETTING: Operating theatre of an University hospital. PATIENTS: 44 unpremedicated, ASA physical status 1 and 2 patients, aged 18-65 years, undergoing insertion or removal of a Port-a-Cath or Hickman catheter. INTERVENTIONS: Patients sedated with a propofol target-controlled infusion were randomly allocated to three groups: Group R25 (n = 14), Group R50 (n = 15), and Group R75 (n = 15), to receive remifentanil 0.025, 0.05, and 0.075 mug\\/kg\\/min, respectively. Rescue remifentanil 0.5 mug\\/kg was administered for pain scores > 3. The remifentanil infusion rate was maintained constant unless respiratory and\\/or cardiovascular unwanted events occurred, whereupon the rate was adjusted in 0.01 mug\\/kg\\/min decrements as necessary. MEASUREMENTS: Pain scores (primary outcome), sedation, and movement scores (secondary outcomes) were assessed during local anesthetic infiltration of the anterior chest wall and 5 other procedural steps. MAIN RESULTS: All infusion rates had equal analgesic efficacy, as shown by comparable pain scores, number of rescue boluses, and number of patients requiring rescue analgesia. Excessive sedation was associated with the highest remifentanil rate such that Group R75 patients were significantly more sedated than Groups R25 or R50 at selective procedural steps (P < 0.05). More Group R75 patients (6\\/15) required remifentanil rate reduction than did patients from Group R50 (1\\/15) or Group R25 (0\\/14), P < 0.01, most commonly because of respiratory depression. CONCLUSIONS: For the insertion or removal of long-term central venous access devices, all three remifentanil infusion rates proved to be equally analgesic

    More than 20% of the world's population use a catheter for dialysis, despite guidelines limiting their use. Although the structure and design of the catheters differ by manufacturer, the material used in central venous catheters and peritoneal dialysis catheters are the same across manufacturers. Given the long-term use of these catheters in the dialysis population, the good compatibility of the antiseptics and disinfectants used on the catheters is imperative to prevent failure and cracking of the catheter material. Tensile strengths of commercially available catheters were measured after exposure to commonly used disinfectants. The tensile strength was then compared between the catheters by analyzing the displacement vs. force (N) curves produced during the evaluation. A total of 44 catheter lumens were evaluated. The electrolytically produced sodium hypochlorite solution, Alcavis 50/ExSept Plus, was the only solution shown to be compatible with all three catheter materials resulting in a deviation of less than 10% for each of the different catheter types. Electrolytically produced sodium hypochlorite solutions were the only solutions in this study that did not alter the physical properties of any of the catheters after long-term exposure.

    Methicillin-resistant Staphylococcus aureus is a frequent cause of hospital-associated infections, including central catheter-associated bacteremia. Vancomycin has been the drug of choice for treating this type of bacteremia for decades in patients who have no contraindications to the antibiotic. However, resistance to vancomycin is an emerging problem. Newer antibiotics approved by the Food and Drug Administration have activity against methicillin-resistant S aureus Some of the antibiotics also have activity against strains of S aureus that are intermediately susceptible or resistant to vancomycin. This article uses a case study to highlight the clinical signs of vancomycin failure and describes the indications for and appropriate use of alternative antimicrobials such as ceftaroline, daptomycin, linezolid, tigecycline, and telavancin.

    To compare prevalence and patterns of intravertebral collateral enhancement in patients with and without central venous obstruction (CVO). Chest CTs performed between 1/1/2000 and 12/15/2012 with reports containing terms indicating CVO were identified. All contrast enhanced CTs were examined for the presence of CVO and collateral venous pathways. If intravertebral collateral enhancement was present, the pattern was recorded as nodular, linear, or both. In 209 suspected cases of CVO, 53 (25 %) were confirmed with obstruction and 156 (75 %) were without obstruction. In patients with CVO, 47 % (25/53) demonstrated collateral venous flow through an intravertebral marrow pathway compared to 5 % (8/156) of patients without CVO (P < 0.0001). The most common level of enhancement was the upper thoracic spine, involving only the vertebral body. Nodular, linear, and combined nodular-linear enhancement patterns were seen with similar frequency. Nodular intravertebral collateral enhancement was mistaken for sclerotic metastases in 33 % (3/9) of cases. Intravertebral collateral enhancement was seen in almost half the patients with CVO and when nodular enhancement is present, it is important to differentiate between metastatic lesions and enhancement related to CVO.

    Background: Most blood tests require venous blood samples. Puncturing the vein also causes pain, infection, or damage to the blood, and lymph flow, or long-term healing. This study aimed to determine and compare the biochemical laboratory value of the blood samples that were provided through: peripheral vein infusion (PVI) receiving continuous intravenous fluid; and the usual method of blood sampling. Methods: This is an interventional, quasi-experimental, and controlled study. The selected study sample included 60 patients, who were hospitalized during 2014, in the Internal Medicine, part of Martyrs of Persian Gulf, teaching hospital at Bushehr. Three blood samples were taken from each patient that were provided through PVI line (5 ml blood collected at beginning of IVC and then another 5 cc), and another case was prepared by common blood sampling (control). All the samples were analyzed in terms of sodium, potassium, urea and creatinine using SPSS Ver.19 software, by paired t-test and Pearson’s correlation coefficients. Results: There was a statistically significant difference between the amount of sodium and potassium in the first blood samples taken from the intravenous infusion line and vein puncture. However, no significant differences were found among the biochemical amount in the second blood samples taken from the intravenous infusion line and vein puncture. Conclusions: We can use blood samples taken from peripheral intravenous infusion lines after 5cc discarding from the first part of the sample for measuring the value of sodium, potassium, urea and creatinine.

    Approximately 9,800 adverse events related to medical tubing are reported in Taiwan every year. Most neonates in critical condition and premature infants acquire fluid, nutrition, and infusion solution using percutaneously inserted central catheters (PICCs). Objective structured clinical examination (OSCE) is an objective evaluative tool that may be used to measure the clinical competence of healthcare professionals. Very little is known about the effects of OSCE in Taiwan in terms of improving the accuracy of use of PICCs in nursing care and of reducing unexpected medical tubing removals. The present project aimed to explore the effects of an OSCE course on these two issues in the realms of standard operating procedures, care protocols, and training equipment at a neonatal intermediate unit in Taiwan. The duration of the present study ran from 2/20/2013 to 10/30/2013. The results showed that nurses' knowledge of PICCs improved from 87% to 91.5%; nurses' skill-care accuracy related to PICCs improved from 59.1% to 97.3%; and incidents of unexpected tube removals declined from 63.6% to 16.7%. This project demonstrated that OSCE courses improve the quality of PICC nursing care. Additionally, the instant feedback mechanism within the OSCE course benefited both teachers and students.

    Full Text Available In recent years an increasing incidence and prevalence of oncological diseases is observed, with a consequent increase in chemotherapies. In order to avoid repeated venipuncture of patients and toxicity in small veins during different cycles of treatment, devices that provide a permanent central venous access are used. The aim of this study was to evaluate the success and safety of port a cath devices inserted by surgery residents. A consecutive case series of patients in whom Port-a-CathTM catheter was placed by residents of surgery in the period from March 2009 to January 2014 were included. A total of 358 Port-a-CathTM catheters were inserted. Average age 58.7 years (16-88. Females 53.1%. Chemotherapy treatment for solid neoplasias (74.8% and for hematological diseases (25.2%. SThe different venous accesses were: Subclavian (67.6%, Cephalic (27.4%, external jugular (3.3%, internal jugular (1.7%. The morbidity rate was 5.3%, twelve patients with catheter-associated infection requiring the removal of it, 3 venous thrombosis with subsequent replacement of the catheter and 4 patients required pleural drainage. Port-a-CathTM catheter placement by residents is a safe and effective procedure for the administration of chemotherapy

    Objective: To evaluate the efficacy of stent placement for treating upper extremity central venous obstruction in chronic hemodialysis patients. Methods and Material: Between January 1999 and October 2001, we inserted metallic stents into the upper extremity central veins of 14 patients with shunt dysfunction and/or arm swelling. The indications for stent placement were stenosis or occlusion of the central vein in the upper extremity used for dialysis. Six of the individuals were diagnosed with subclavian vein stenosis, and 5 with brachiocephalic vein stenosis. Of the remaining 3 patients, 2 had subclavian vein occlusion, and 1 had left brachiocephalic vein occlusion. Results: All the stent placement procedures were technically successful, and there were no major complications. Follow-up ranged from 2 weeks to 29 months. The 1-, 3-, 6- and 12-month primary stent patency rates were 92.8, 85.7, 50 and 14.3%, respectively. Repeat interventions, including percutaneous transluminal angioplasty and additional stent placement, were required in 9 patients. The 3-, 6-, 12-month, and 2-year assisted primary stent patency rates were 100, 88.8, 55.5 and 33.3%, respectively. Conclusion: Endovascular stent placement is an effective alternative to surgery in patients with shunt dysfunction due to obstruction of an upper extremity central vein. Repeated interventions are usually required to prolong stent patency.

    Excess blood pressure remains the most important risk factor for cardiovascular and renal disease. Poly pharmacy has been proved safe and effective under clinical trial circumstances; however, the majority of patients fail to sustain pharmaceutical persistence and adherence. The opportunity to offer patients a treatment or device in addition or perhaps instead of drug therapy alone may significantly broaden the options for patients and allow greater success in hypertensive therapy. In this review, we examine the potential of a fixed-volume central arterial-venous anastomosis to reduce blood pressure in hypertensive patients, review possible mechanisms by which the anastomosis may reduce blood pressure, and consider the unique clinical trial opportunities posed by this therapy.

    Intracranial complications of sinusitis are rare but life threatening. We present a case of a 17-year-old woman with sinusitis who deteriorated over the course of 12 days from subdural empyema and global purulent cerebral venous sinus thrombosis. The patient was managed with surgery and mechanical thrombectomy utilizing a novel 'stent anchor with mobile aspiration technique', in which a Trevo stent retriever (Stryker) was anchored in the superior sagittal sinus (SSS) while a 5 MAX ACE reperfusion catheter (Penumbra) was passed back and forth from the SSS to the sigmoid sinus with resultant dramatic improvement in venous outflow. The patient was extubated on postoperative day 3 and was discharged with minimal lower extremity weakness on postoperative day 11. This is the first report using the Trevo stent retriever for sinus thrombosis. It is important to keep these rare complications in mind when evaluating patients with oral and facial infections.

    Totally Implantable Central Venous Access Devices (Intraports) are commonly used in cancer patients to administer chemotherapy or parenteral nutrition. These devices are placed by Seldinger technique. We report an unusual case of intraport catheter rupture before the use of the device. The ruptured part of the catheter migrated into the left pulmonary vein via right ventricle. The ruptured part was removed by means of interventional radiology before causing any problems to the patient. All the reported ruptures of port catheters refer to port devices that had been used to administer chemotherapy, fluids, or parenteral nutrition. The unique feature of this case is that the catheter had not been used at all. It is of great interest also the removal of the broken part from the pulmonary vein.

    Background: Central venous disease is a serious complication in patients undergoing hemodialysis, often presenting with symptoms of venous hypertension. Treatment is aimed to provide symptomatic relief and to maintain hemodialysis access site patency. Aim: To describe our initial experience in the endovascular treatment of central venous stenosis or obstruction in patients undergoing hemodialysis. Settings and Design: This was a retrospective study carried out in a tertiary care center. Study duration was 24 months. Follow-up was variable. Materials and Methods: Eleven patients of chronic renal failure undergoing hemodialysis presented with central vein stenosis or obstruction having ipsilateral vascular access, between July 2012 and July 2014. All the patients underwent endovascular treatment and were analyzed retrospectively. Results and Conclusion: A total of 11 patients (4 male and 7 female) underwent 18 interventions for 13 stenotic segments during a time period of 2 years. Eight stenotic segments were in brachiocephalic vein, three in subclavian vein, and two in axillary veins. The technical success rate for endovascular treatment was 81.8%. Two patients underwent percutaneous transluminal angioplasty (PTA) alone and presented with restenosis later. Balloon angioplasty followed by stenting was done in seven patients, two of which required reintervention during follow-up. We found endovascular treatment safe and effective in treating central venous disease. PMID:26752817

    Full Text Available Introduction: Central venous catheterization (CVC can be an important component of the management of patients with severe sepsis and septic shock. CVC, however, is a time- and resource-intensive procedure associated with serious complications. The effects of the absence of shock or the presence of relative contraindications on undertaking central line placement in septic emergency department (ED patients eligible for early goal-directed therapy (EGDT have not been well described. We sought to determine the association of relative normotension (sustained systolic blood pressure >90 mmHg independent of or in response to an initial crystalloid resuscitation of 20 mL/kg, obesity (body mass index [BMI] ≥30, moderate thrombocytopenia (platelet count <50,000 per μL, and coagulopathy (international normalized ratio ≥2.0 with unattempted CVC in EGDT-eligible patients. Methods: This was a retrospective cohort study of 421 adults who met EGDT criteria in 5 community EDs over a period of 13 months. We compared patients with attempted thoracic (internal jugular or subclavian CVC with those who did not undergo an attempted thoracic line. We also compared patients with any attempted CVC (either thoracic or femoral with those who did not undergo any attempted central line. We used multivariate logistic regression analysis to calculate adjusted odd ratios (AORs. Results: In our study, 364 (86.5% patients underwent attempted thoracic CVC and 57 (13.5% did not. Relative normotension was significantly associated with unattempted thoracic CVC (AOR 2.6 95% confidence interval [CI], 1.6-4.3, as were moderate thrombocytopenia (AOR 3.9; 95% CI, 1.5-10.1 and coagulopathy (AOR 2.7; 95% CI, 1.3-5.6. When assessing for attempted catheterization of any central venous site (thoracic or femoral, 382 (90.7% patients underwent attempted catheterization and 39 (9.3% patients did not.

    2014-01-01

    Full Text Available We describe an unusual case of subphrenic abscess complicating a central venous catheter infection caused by Pseudomonas aeruginosa in a 59-year-old woman undergoing hemodialysis. The diagnosis was made through computed tomography, and Pseudomonas aeruginosa was isolated from the purulent drainage of the subphrenic abscess, the catheter tip and exit site, and the blood culture samples. A transesophageal echocardiography showed a large tubular thrombus in superior vena cava, extending to the right atrium, but no evidence of endocarditis or other metastatic infectious foci. Catheter removal, percutaneous abscess drainage, anticoagulation, and antibiotics resulted in a favourable outcome.

  2. Ethanol causes protein precipitation--new safety issues for catheter locking techniques.

    Directory of Open Access Journals (Sweden)

    Gernot Schilcher

    Full Text Available OBJECTIVE: The ethanol lock technique has shown great potential to eradicate organisms in biofilms and to treat or prevent central venous catheter related infections. Following instillation of ethanol lock solution, however, the inherent density gradient between blood and ethanol causes gravity induced seepage of ethanol out of the catheter and blood influx into the catheter. Plasma proteins so are exposed to highly concentrated ethanol, which is a classic agent for protein precipitation. We aimed to investigate the precipitating effect of ethanol locks on plasma proteins as a possible cause for reported catheter occlusions. METHODS: Plasma samples were exposed in-vitro to ethanol (concentrations ranging from 7 to 70 v/v% and heparin lock solutions. In catheter studies designed to mimic different in-vivo situations, the catheter tip was placed in a plasma reservoir and the material contained within the catheter was analyzed after ethanol lock instillation. The samples underwent standardized investigation for protein precipitation. RESULTS: Protein precipitation was observed in plasma samples containing ethanol solutions above a concentration of 28%, as well as in material retrieved from vertically positioned femoral catheters and jugular (subclavian catheters simulating recumbent or head down tilt body positions. Precipitates could not be re-dissolved by dilution with plasma, urokinase or alteplase. Plasma samples containing heparin lock solutions showed no signs of precipitation. CONCLUSIONS: Our in-vitro results demonstrate that ethanol locks may be associated with plasma protein precipitation in central venous catheters. This phenomenon could be related to occlusion of vascular access devices locked with ethanol, as has been reported. Concerns should be raised regarding possible complications upon injection or spontaneous gravity induced leakage of such irreversibly precipitated protein particles into the systemic circulation. We suggest

    The use of endovascular catheters is a routine practice in secondary and tertiary care level hospitals. Short peripheral catheters have been found to be associated with the risk of nosocomial bacteremia resulting in morbidity and mortality. Staphyloccus aureus is mostly associated with peripheral catheter insertion. This Consensus Document has been elaborated by a panel of experts of the Spanish Society of Cardiovascular Infections in cooperation with experts from the Spanish Society of Internal Medicine, Spanish Society of Chemotherapy and Spanish Society of Thoracic-Cardiovascular Surgery and aims at define and establish the norm for management of short duration peripheral vascular catheters. The document addresses the indications for insertion, catheter maintenance and registry, diagnosis and treatment of infection, indications for removal and stresses on continuous education as a driver for quality. Implementation of this norm will allow uniformity in usage thus minimizing the risk of infection and its complications. PMID:27580009

    Central venous catheters (CVCs) are commonly used in clinical practice. One of the foremost complications associated with their use is the potential for symptomatic or asymptomatic thrombosis. CVC thrombosis, in turn, may not only result in vascular and catheter occlusion but also infection, pulmonary embolism, and formation of right heart thromboemboli. Thrombi within cardiac chambers are associated with an increased risk of mortality due to their potential for embolization to the pulmonary ...

  5. Peripheral Venous Access Ports: Outcomes Analysis in 109 Patients

    International Nuclear Information System (INIS)

    Purpose: To perform a retrospective outcomes analysis of central venous catheters with peripheral venous access ports, with comparison to published data.Methods: One hundred and twelve central venous catheters with peripherally placed access ports were placed under sonographic guidance in 109 patients over a 4-year period. Ports were placed for the administration of chemotherapy, hyperalimentation, long-term antibiotic therapy, gamma-globulin therapy, and frequent blood sampling. A vein in the upper arm was accessed in each case and the catheter was passed to the superior vena cava or right atrium. Povidone iodine skin preparation was used in the first 65 port insertions. A combination of Iodophor solution and povidone iodine solution was used in the last 47 port insertions. Forty patients received low-dose (1 mg) warfarin sodium beginning the day after port insertion. Three patients received higher doses of warfarin sodium for preexistent venous thrombosis. Catheter performance and complications were assessed and compared with published data.Results: Access into the basilic or brachial veins was obtained in all cases. Ports remained functional for a total of 28,936 patient days. The port functioned in 50% of patients until completion of therapy, or the patient's expiration. Ports were removed prior to completion of therapy in 18% of patients. Eleven patients (9.9% of ports placed) suffered an infectious complication (0.38 per thousand catheter-days)-in nine, at the port implantation site, in two along the catheter. In all 11 instances the port was removed. Port pocket infection in the early postoperative period occurred in three patients (4.7%) receiving a Betadine prep vs two patients (4.2%) receiving a standard O.R. prep. This difference was not statistically significant (p = 0.9). Venous thrombosis occurred in three patients (6.8%) receiving warfarin sodium and in two patients (3%) not receiving warfarin sodium. This difference was not statistically significant

    We report an unusual case of lumbosacral osteogenic sarcoma with cauda equina syndrome and invasion into the central venous and cardiac system. A 41-year-old Hispanic man presented to the emergency department complaining of severe low back pain, cauda equina syndrome, bilateral lower extremity edema, and an extra heart sound on physical examination. CT of the lumbosacral spine done in the emergency department demonstrated a sclerotic lesion in the sacrum with cortical destruction, extension into the spinal canal and a bulky soft tissue mass containing calcifications. Supplemental MRI demonstrated marrow replacement of L4, L5, and the sacrum, soft tissue extension of the tumor, and invasion iliac veins extending into the IVC; however, the full extent of the intravascular tumor was not seen on this examination. Surgical laminectomy and biopsy of the spinal tumor provided the diagnosis of osteogenic sarcoma. A transthoracic echocardiogram was performed while the patient was recovering due to nonsustained ventricular tachycardia, which showed an echogenic mass within the right atrium and ventricle. CT pulmonary angiogram confirmed the echocardiogram showing a tumor extending through the pulmonary valve into the main pulmonary artery. The patient underwent en bloc resection of the tumor from the venous and cardiac systems. Histologic examination of the tumor confirmed osteogenic sarcoma. While vertebral osteogenic sarcoma is uncommon, invasion of the spinal canal is common in these tumors. However, tumor extending into the central venous and cardiac system is rare. The previously reported cases of central venous and cardiac involvement have been related to distant metastases or primary cardiac osteosarcomas. There is only one other reported case of direct extension into the venous system by an iliac bone osteosarcoma in an adolescent; however, the tumor did not extend into the pulmonary circulation.

    OBJECTIVE: Despite controversy about whether peripheral and central venous catheters should be locked with heparin to prevent catheter-associated clotting, the practice is widespread. We describe a severe side effect of the practice: a case of heparin-induced thrombocytopenia occurring with catheter flushes using unfractionated heparin (UFH) in a 10-month-old boy successfully treated with danaparoid. Patient: A preterm-born patient (33 wks gestational age, birth weight 1200 g) suffering from VACTERL syndrome was repeatedly treated with UFH in the context of several invasive procedures. On day 310 of age, a central venous catheter was inserted to provide total parenteral nutrition. The central catheter was flushed with a continuous infusion of UFH at 100 U/day, and a decrease in platelet counts from 150,000/&mgr;L (on day 310 of age) to 45,000/&mgr;L (on day 319 of age) was observed. Clinically suspected heparin-induced thrombocytopenia (HIT) was serologically confirmed by demonstrating HIT antibodies with platelet factor 4/heparin complex specificity. Main Result: Catheter flushing was switched to low-dose danaparoid sodium as a continuous infusion at 15 anti-factor Xa units per day. Two days later, platelet counts recovered. Neither catheter thrombosis nor systemic thromboembolic complications occurred during the follow up period. CONCLUSIONS: Even continuous infusion of low-dose heparin to provide patency of central venous port catheters may trigger the primary immune response of HIT. Low-dose danaparoid sodium, a heparinoid, can prevent in-catheter thrombus formation and allows normalization of platelet counts in acute HIT. PMID:12797878

    2007-01-01

    Objective: To analyze catheter-related complications during postoperative Intraperitoneal chemotherapy (IPCT) for gastric cancer. Methods: From December 2003 to April 2007, 80 patients with gastric cancer were treated with postoperative IPCT using central venous catheters (CVCs), during which the complications that occurred in association with CVCs were documented and analyzed. Results: Catheter-related complications were seen in 10 out of the 80 patients, yielding a total complication rate of 12.5%. Main complications included abdominal pain (3.8%), local infection (1.3%), catheter obstruction (2.5%), leakage (2.5%) and dislocation (2.5%). All patients successfully finished their IPCT, the success rate was 100%. There occurred no severe complications or treatment-related deaths. Conclusion: It is convenient and safe to carry out postoperative IPCT for gastric cancer using CVCs, which, with a low catheter-related complication rate, should be recommended for more clinic use.

    Full Text Available Abstract Background The extent to which medical residents are involved in the teaching and supervision of medical procedures is unknown. This study aims to evaluate the teaching and supervision of junior residents in central venous catheterization (CVC by resident-teachers. Methods All PGY-1 internal medicine residents at two Canadian academic institutions were invited to complete a survey on their CVC experience, teaching, and supervision prior to their enrolment in a simulator CVC training curriculum. Results Of the 69 eligible PGY-1 residents, 32 (46% consenting participants were included in the study. There were no significant baseline differences between participants from the two institutions in terms of sex, number of ICU months completed, previous CVC training received, number of CVCs observed and performed. Only 16 participants (50% received any CVC training at baseline. Of those who received any training, 63% were taught only by senior resident-teachers. A total of 81 CVCs were placed by 17 participants. Thirty-two CVCs (45% were supervised by resident-teachers. Conclusions Resident-teachers play a significant role both in the teaching and supervision of CVCs placed by junior residents. Educational efforts should focus on preparing residents for their role in teaching and supervision of procedures.

  12. Challenges in the Management of Pediatric Central Venous Access Devices in the Community.

    2012-05-25

    Central venous access devices (CVADs) play an essential role in the care of critically ill children. Significant challenges exist for teams in managing CVADs particularly in a community setting. The authors aimed to assess the experience of general practitioners (GPs) caring for children with CVADs. From 200 CVADs inserted in a pediatric hospital in 2009, 50 patients were randomly selected and 44 GPs were forwarded a questionnaire. Twenty (46%) GPs responded. The main reasons (n = 22) for using CVADs were medication administration (n = 11), nutrition (n = 6), and blood sampling (n = 5). Thirteen (65%) GPs had no education in CVAD management and 14 (70%) were unaware of existing guidelines. Those identified by GPs as having primary responsibility for care of CVADs in the community included hospital\\/pediatric teams (n = 9), parents (n = 3), GPs (n = 2), public health nurses (n = 1), and palliative care ("home care") teams (n = 1). The main challenges (n = 15) identified by GPs were lack of education (n = 4), line management difficulties (n = 3), infection risk (n = 3), infrequent exposure to CVADs (n = 3), and poor communication (n = 1). GPs felt that these challenges could be addressed through: education (n = 8), increased manpower and community support (n = 1), and improved communication (n = 1). This study highlights the inconsistency and challenges for GPs surrounding CVAD use in children. Further education and support is necessary to assist GPs in their use particularly when providing end-of-life care for children in the community.

    To evaluate the impact of interventional radiological imaging and treatment of central venous port catheter complications. Materials and Methods: In this retrospective analysis 429 port catheter dysfunctions were evaluated in 393 port catheter systems for a total of 389 patients over a period of 10 years. The study included 193 (49.1 %) patients with radiologically implanted port catheter systems and 200 (50.9 %) referred patients with surgically implanted port systems. Port catheter dysfunctions were subdivided into early and late complications as well as into non-thrombotic and thrombotic events. After administration of contrast medium, the port system was visualized using digital subtraction angiography. Data were retrospectively collected from the in-house databases and then analyzed descriptively. Results: 429 contrast media injections via port catheters were performed in 393 port catheter systems. There were 359 (83.7 %) late complications and 70 (16.3 %) early complications. In 299 (69.7 %) cases thrombotic events occurred and 130 (30.3 %) non-thrombotic events were recorded. The most common reason for contrast media injection via port catheter system was port catheter-related thrombosis in 269 (62.7 %) cases. 70 (16.3 %) catheter migrations and 30 (7.0 %) fibrin sheath formations were detected. 18 (4.2 %) port needle malfunctions could be resolved through needle exchange. All 15 (3.5 %) catheter disconnections had to be revised in all cases. Also six port explantations were performed in 6 (1.4 %) catheter fractures. Conclusion: The possibilities of angiographic imaging and interventional radiological correction of port catheter dysfunctions must be exploited fully in order to avoid premature port explantation.

    Venous access is an essential part of medical practice. It is needed to obtain blood samples to make the diagnosis and to administer fluids or medicines as part of treatment. Although relatively new in the history of medicine, the placement and maintenance of the various venous access devices now occupies a significant portion of many vascular and interventional radiology practices. Thus, it is important to have a thorough understanding of these devices and their uses. The first long-term venous access devices were used in 1973. These were placed via a surgical cut-down on the subclavian vein. In 1982, the first subcutaneous implantable ports were described. These procedures were initially performed by surgeons, but over the last 5-10 years, both the insertion and management of these devices has shifted to interventional radiologists. Peripherally inserted central catheter (PICC) lines have almost completely supplanted the use of standard central lines (Fig. 1). A number of factors have facilitated this - namely, ready and less expensive room access, outpatient procedure and radiologists' accessibility and familiarity with image-guidance procedures and catheters and guide wires.

    The subcutaneous venous access device (SVAD or 'port') is a critical component in the care of patients with chronic disease. The modern SVAD provides reliable access for blood withdrawal and medication administration with minimal disruption to a patient's lifestyle. Because of improved materials and catheter technology, today's ports are lighter and stronger and capable of high-pressure injections of contrast for cross-sectional imaging. The majority of SVAD placement occurs in interventional radiology departments due to their ability to provide this service at lower costs, lower, complication rates, and greater volumes. Port-insertion techniques vary depending on the operator, but all consist of catheter placement in the central venous circulation followed by subcutaneous pocket creation and port attachment to the catheter with fixation and closure of the pocket. Venous access challenges occasionally occur in patients with central vein occlusions, necessitating catheterization of collateral veins or port placement in alternate locations. Complications of SVADs include those associated with the procedure as well as short- (<30 days) and long-term problems. Procedural and early complications are quite rare due to the near-universal use of real-time ultrasound guidance for vein puncture, but they can include hematoma, catheter malposition, arrhythmias, and pneumothorax. Late problems include both thrombotic complications (native venous or port-catheter thrombosis) and infections (tunnel or pocket infections or catheter-associated bloodstream infections). Most guidelines suggest that 0.3 infections/1000 catheter days is an appropriate upper threshold for the insertion of SVADs.

    Catheter fracture is a rare but serious complication of a peripherally inserted central catheter ( PICC) . An adolescent patient was sent to Tianjin Medical University General Hospital ( Tianjin, China) because the PICC was fractured when removed by a nurse. Chest X-ray showed that the PICC fragment slid into the right pulmonary artery. Through emergency surgery, the remainder of the PICC was successfully retrieved by an interventional operation percutaneously via the right femoral vein. PICC fracture is less common and always without significant discomfort if not found timely, and it may lead to serious complications, such as pulmonary embolism, and even death. Thus, nurses, patients and their family members should pay enough attention to the daily mainte-nance of PICC and have a deep understanding of the reasons associated with PICC fracture as well as how to prevent it. Interventional operation is minimally invasive, which is a good choice for the removal of intravascular foreign bodies, leading to fewer complications and a good prognosis.

    Full Text Available Background and Aims: Tissue hypoperfusion is reflected by metabolic parameters such as lactate, central venous oxygen saturation (ScvO 2 and the veno-arterial CO 2 (vaCO 2 difference. We studied the relation of these parameters over time and with outcome in patients with severe septic shock. Materials and Methods: In this single-center, prospective observational cohort study, adult patients (≥18 years with circulatory shock were included. Echocardiography and simultaneous arterial and venous blood gases were done on enrolment (0 h and at 24, 48 and 72 h. The partial pressure of CO 2 , lactate and ScvO 2 were recorded from the central venous blood samples. The vaCO 2 was calculated as the difference in CO 2 between paired venous and arterial blood gas samples. Results: Of the 104 patients with circulatory shock, 79 patients (44 males with septic shock aged 49.8 (standard deviation ± 14.6 years and with sequential organ failure assessment (SOFA score of 11.0 ± 3.4 were included. 71 patients (89.9% were ventilated (11.4 ± 12.3 ventilator-free days. The duration of hospitalization was 16.6 ± 12.8 days and hospital mortality 50.6%. Lactate significantly decreased over time with a greater decrement in survivors than nonsurvivors (−0.35 vs. −0.10, P 70% and not in ScvO 2 ≤70%. Conclusion: In septic shock, vaCO 2 ≤6 mmHg is independently associated with mortality, particularly in those with normalized ScvO 2 consistent with metabolic microcirculatory abnormalities in these patients.

  3. The impact of sodium citrate on dialysis catheter function and frequency of catheter-related bacteriemia and haemorrhage

    Full Text Available Vascular access is one of the most important problems of hemodialysis therapy. It is known that an arteriovenous fi sutla provides the best vascular access, but its creation is not always possible. Other solutions, such as the insertion of a central venous catheter, are then required. Adequate protection of such catheters by interdialytic fi ll with locking solution affects the frequency of hemodialysis-related complications. The most widespread catheter locking solution is heparin. Sodium citrate is being used more frequent recently. Available data indicate that hemorrhage is 11.9 times more frequent if the catheter locking solution is 5000 IU/ml heparin than if 4�0sodium citrate or 1000 IU/ml heparin is used. Other data indicate that the frequency of infection is statistically decreased when 30�0sodium citrate is used to fi ll the catheter instead of 5000 IU/ml heparin. Analogous data on 46.7�0sodium citrate are not consistent. It seems that the use of 4�0sodium citrate instead of 5000 IU/ml heparin does not decrease the frequency of infections. Numerous studies indicate that sodium citrate at various concentrations exerts a positive infl lence on catheter function. However, not all data are in accord. The spill of sodium citrate from the catheter to the systemic circulation is connected with a risk of adverse events. It may be dangerous if the citrate concentration is 46.7�20However, adequate fi lling of the catheter should prezent such events. Available data indicate that fi lling of the catheter with a solution of citrate of a concentration of no more than 30�0should be safe. Data on 46.7�0citrate are not conclusive, so precautions should be taken.

    Full Text Available Abstract Background A central venous catheter (CVC currently represents the most frequently adopted intravenous line for patients undergoing infusional chemotherapy and/or high-dose chemotherapy with hematopoietic stem-cell transplantation and parenteral nutrition. CVC insertion represents a risk for pneumothorax, nerve or arterial punctures. The aim of this prospective observational study was to explore the safety and efficacy of CVC insertion under ultrasound (US guidance and to confirm its utility in clinical practice in cancer patients. Methods Consecutive adult patients attending the oncology-hematology department were eligible if they had solid or hematologic malignancies and required CVC insertion. Four types of possible complication were defined a priore: mechanical, thrombotic, infection and malfunctioning. The patient was placed in Trendelenburg's position, a 7.5 MHZ puncturing US probe was placed in the supraclavicular site and a 16-gauge needle was advanced under real-time US guidance into the last portion of internal jugular vein. The Seldinger technique was used to place the catheter, which was advanced into the superior vena cava until insertion into right atrium. Within two hours after each procedure, an upright chest X-ray and ultrasound scanning were carried out to confirm the CVC position and to rule out a pneumotorax. CVC-related infections, symptomatic vein thrombosis and malfunctioning were recorded. Results From December 2000 to January 2009, 1,978 CVC insertional procedures were applied to 1,660 consecutive patients. The procedure was performed 580 times in patients with hematologic malignancies and 1,398 times those with solid tumors. A single-needle puncture of the vein was performed on 1,948 of 1,978 procedures (98.48%; only eighteen attempts among 1,978 failed (0.9%. No pneumotorax, no major bleeding, and no nerve puncture were reported; four cases (0.2% showed self-limiting hematomas. The mean lifespan of CVC was 189

    Purpose: To evaluate whether catheter-related infections after radiologically placed port catheters can be reduced by single-shot periinterventional antibiosis. Materials and Method: Between January and September 2002, 164 consecutive patients with indication for central venous port catheter implantation were included in the present study. During implantation the interventional radiologist was responsible for deciding whether to administer a prophylactic single-shot antibiosis. The prophylactic antibiosis entailed intravenous administration of ampicillin and sulbactam (3 g Unacid, Pfizer) or 100 mg ciprofloxacine (Ciprobay, Bayer) in the case of an allergy history to penicillins. Catheter-related infection was defined as a local or systemic infection necessitating port catheter extraction. Results: Indication for port catheter implantation was a malignant disease requiring chemotherapy in 158 cases. The port catheter (Chemosite [Tyco Healthcare] [n = 123], low-profile [Arrow International] [n = 35], other port system [n = 6]) was implanted via sonographically guided puncture of the right jugular vein in 139 patients, via the left jugular vein in 24 cases and via the right subclavian vein in one patient. 75 patients received periinterventional prophylactic antibiosis (Unacid [n = 63] Ciprobay [n = 12]) and 89 patients did not receive antibiosis. The prophylactic antibiosis caused a minor allergic reaction in one patient that improved with antihistamic and corticoid medication. A total of 7 ports, 6 without prophylactic antibiosis versus one with periinterventional prophylaxis, were extracted due to infectious complications. Conclusion: Single-shot periinterventional prophylactic antibiosis can reduce early and late infectious complications after radiological-interventional placement of central venous port catheters.

    Full Text Available Central venous catheter-related blood stream infection is a major cause of morbidity and mortality in patients with renal disease treated with hemodialysis. Antibiotic lock solutions can be effective in preventing this complication in patients with hemodialysis. Searching in Epistemonikos database, which is maintained by screening more than twenty databases, we identified eight systematic reviews including seventeen randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded that antibiotic lock solutions probably decrease catheter-related blood stream infection in hemodialysis patients.

The capacitance of the catheter surfaces was measured and, to determine if the catheters released ions, distilled water was passed through and current measured as a function of voltage. With probes touching the inner and outer surfaces, capacitance was not voltage-dependent, indicating surfaces were uncharged or carried a similar charge. When one probe penetrated the catheter wall, capacitance was weakly voltage-dependent, indicating the presence of a surface charge. Standard and charged catheters were also exposed to phosphate buffered saline as controls or 2×106 colony forming units/mL (in phosphate buffered saline of six different microorganisms for 60 or 120 minutes. When the growth of detached bacteria was measured, biofilm formation was significantly reduced, (P<0.05, for charged catheters for all organisms.Keywords: central venous catheters, electrical charge, biofilm

    BACKGROUND The number of peripherally inserted central catheter (PICC) lumens is associated with thrombotic and infectious complications. Because multilumen PICCs are not necessary in all patients, policies that limit their use may improve safety and cost. OBJECTIVE To design a simulation-based analysis to estimate outcomes and cost associated with a policy that encourages single-lumen PICC use. METHODS Model inputs, including risk of complications and costs associated with single- and multilumen PICCs, were obtained from available literature and a multihospital collaborative quality improvement project. Cost savings and reduction in central line-associated bloodstream infection and deep vein thrombosis events from institution of a single-lumen PICC default policy were reported. RESULTS According to our model, a hospital that places 1,000 PICCs per year (25% of which are single-lumen and 75% multilumen) experiences annual PICC-related maintenance and complication costs of $1,228,598 (95% CI, $1,053,175-$1,430,958). In such facilities, every 5% increase in single-lumen PICC use would prevent 0.5 PICC-related central line-associated bloodstream infections and 0.5 PICC-related deep vein thrombosis events, while saving $23,500. Moving from 25% to 50% single-lumen PICC utilization would result in total savings of $119,283 (95% CI, $74,030-$184,170) per year. Regardless of baseline prevalence, a single-lumen default PICC policy would be associated with approximately 10% cost savings. Findings remained robust in multiway sensitivity analyses. CONCLUSION Hospital policies that limit the number of PICC lumens may enhance patient safety and reduce healthcare costs. Studies measuring intended and unintended consequences of this approach, followed by rapid adoption, appear necessary. Infect Control Hosp Epidemiol 2016;37:811-817. PMID:27033138

    This case reports describes a 39-year-old female with a history of surgically repaired hypoplastic left heart syndrome who presented with a left peripherally inserted central catheter (PICC) with associated large volume subclavian and brachiocephalic vein thrombus. Due to the presence of a right-to-left shunt via a fenestrated Fontan, there was clinical concern for a paradoxical embolism during removal of the PICC. The AngioVac aspiration system was successfully utilized to aspirate thromboemboli from the level of the proximal Glenn shunt during manipulation and removal of the PICC. This is the first reported case to demonstrate the safe and effective use of the AngioVac aspiration system for protection of paradoxical emboli through a cardiac right-to-left shunt during a procedure at high risk for thromboembolism.

    In current clinical practice, peripherally inserted central catheters (PICCs) are typically inserted using external anatomical measurements and a confirmatory chest X-ray, or using fluoroscopy. The Sherlock 3CG(®) Tip Confirmation System (TCS) allows magnetic tracking of the PICC tip during insertion and confirmation of the final location using ECG, meaning that most patients will not require a chest X-ray or fluoroscopy. The Sherlock 3CG(®) TCS was evaluated in 2014 by the UK National Institute for Health and Care Excellence (NICE) as part of the Medical Technologies Evaluation Programme. The company (C.R. Bard Ltd) identified four abstracts, one paper pending publication and questionnaire data from NHS users of the Sherlock 3CG(®) TCS. None of the evidence included a comparator arm. Placement accuracy of PICCs using the Sherlock 3CG(®) TCS where a chest X-ray was also used ranged from 79.5 to 100 %. The company reported that 9 out of 16 NHS centres that used the Sherlock 3CG(®) TCS were no longer using chest X-rays to routinely confirm PICC tip location. The evidence did not report the need for catheter repositioning, re-insertion, staff time savings, treatment delays, length of stay, quality of life outcomes or complications. The company's model found that the Sherlock 3CG(®) TCS was cost saving by GBP25.67 per patient compared to blind bedside PICC insertion. The External Assessment Centre (EAC) adapted the company's model to test alternative assumptions for nurse time, theatre cost, malposition rate and reinsertion method, and found that the Sherlock 3CG(®) TCS was cost incurring by GBP9.37 per patient compared to blind bedside PICC insertion. The use of the Sherlock 3CG(®) TCS in the UK NHS compared to blind PICC insertion using a confirmatory chest X-ray appears to hover around being cost neutral. Staff time and accuracy were key drivers in the model: evidence for these is sparse and the reality will vary in different situations. If evidence became

    Full Text Available After creation of an arteriovenous fistula or placement of an arteriovenous graft, several weeks are required for maturation prior to first cannulation. Patients need an alternative way to receive hemodialysis during this time, frequently a catheter. After multiple failed access attempts, patients can run out of options and become catheter dependent. At our institution, we place HeRO grafts in eligible patients who have otherwise been told they would be catheter dependent for life. By combining the HeRO graft system with a Flixene graft, patients are able to remove catheters sooner or avoid placement as they can undergo cannulation for hemodialysis the next day. Utilizing this novel technique, twenty-one patients over a two-year period with various forms of central venous stenosis, catheter dependence, or failing existing arteriovenous access have been successfully converted to stable long term noncatheter based upper extremity access.

    Full Text Available Objective. To report the experience of a percutaneous technique for retrieving fractured peripherally inserted central catheter (PICC segments migrating into the heart or the pulmonary artery. Method. From April 2013 to July 2015, we performed percutaneous retrieval of fractured PICC segments migrating into the heart or the pulmonary artery in five cancer patients who had undergone chemotherapy via PICC. The fractures were diagnosed with chest plain radiography. The patients included three cases of breast cancer, one case of rectal cancer, and one case of lower limb Ewing’s tumor. The fractures were retained in the vessels of the patients for 1 to 3 days. All the fractures were retrieved by using a novel two-step technique in the digital subtraction angiography (DSA suite. This two-step technique involves inserting a pigtail catheter to the heart or the pulmonary artery to grasp the fractured catheter fragment and bring it to the lower segment of the inferior vena cava, followed by grasping and removing the catheter fragment with a retrieval loop system of the vena cava filter retrieval set. Result. The fractured PICC segments were removed successfully in all five patients via unilateral (four patients or bilateral (one patient femoral vein access. No complications occurred during the interventional procedure. Conclusion. Percutaneous retrieval can be a safe, convenient, and minimally invasive method for the removal of fractured PICC segments. The technique reported in this paper will be applicable for the retrieval of fractured PICC segments and other catheter fragments migrating into the heart or the pulmonary artery.

    Objective: The aim of our research was to study the incidence, clinical diagnosis and treatment of peripherally inserted central catheters (PICC)-related sepsis in breast cancer patients carrying PICC catheter for chemotherapy. Methods: The data of the incidence, diagnosis and treatment of PICC-related sepsis in 215 cases of breast cancer patients carrying PICC catheter for chemotherapy in our hospital from August, 2009 to September, 2011 were analyzed retrospectively. Results: 216 PICCs had been successfully applied in 215 cases of breast cancer patients and followed for a total of 19,109 catheter days, (median catheterization duration, 88.9 days, range 1-212 days). Among those, 3 (1.39%) PICCs were removed respectively as a result of PICC-related sepsis in 29, 73 and 108 catheter-days (median 70 d), with a rate of 0.16 per 1000 catheter-days. Conclusion: Chemotherapeutic treatment via PICC for breast cancer patients is one of the most secure and effective measures but there exists small number of cases in which PICC catheter related sepsis is possible. Careful observation of relevant symptoms and signs, early diagnosis and treatment, not relying completely on blood culture tests and timely removal of PICC catheter can be very effective in treating PICC-related sepsis in these patients.

  4. Interventional radiology with venous port (chemotherapy and infusional support)

    International Nuclear Information System (INIS)

    A completely portable permanent central venous access, consisting of a steel capsule sealed with a silicone membrane and connected to a silicone catheter (Port-a-Cath), was implanted in the subcutaneous tissue of 36 patients, most of whom no longer had accessible peripheral veins and needed to continue chemotherapy or undergo total parenteral nutrition. The access vessel was mostly the subclavian vein and the capsule was sutured to the pectoral fascia. Total subcutaneous implantation seems to afford optimum safety from infection and freedom for personal hygiene, produced no noteworthy complications and proved relatively simple to maintain. (orig.)

    The use of checklists is recommended for the assessment of competency in central venous catheterization (CVC) insertion. To explore the use of a global rating scale in the assessment of CVC skills, this study seeks to compare its use with two checklists, within the context of a formative examination using simulation. Video-recorded performances of CVC insertion by 34 first-year medical residents were reviewed by two independent, trained evaluators. Each evaluator used three assessment tools: a ten-item checklist, a 21-item checklist, and a nine-item global rating scale. Exploratory principal component analysis of the global rating scale revealed two factors, accounting for 84.1% of the variance: technical ability and safety. The two checklist scores correlated positively with the weighted factor score on technical ability (0.49 [95% CI 0.17-0.71] for the 10-item checklist; 0.43 [95% CI 0.10-0.67] for the 21-item checklist) and negatively with the weighted factor score on safety (-0.17 [95% CI -0.48-0.18] for the 10-item checklist; -0.13 [95% CI -0.45-0.22] for the 21-item checklist). A checklist score of 80% on both checklists. All these candidates committed serious errors. In conclusion, the practice of universal adoption of checklists as the preferred method of assessment of procedural skills should be questioned. The inclusion of global rating scales should be considered. PMID:21877217

    Central venous access device (CVAD) insertion is one of the most common procedures performed on paediatric haemophilia patients. There are no clear guidelines outlining the optimal dosing schedule of factor VIII (FVIII) and duration of treatment required to achieve adequate haemostasis during and after surgery. In this article, we describe the experience at McMaster Children's Hospital using FVIII replacement therapy in 15 children with severe haemophilia A during the course of 7 years. This is a retrospective institutional chart review. Patients between 0 and 18 years of age with severe haemophilia A that underwent CVAD insertion at McMaster Children's Hospital in Hamilton, Ontario, from 2004 to 2010, were identified and charts were reviewed. A total of 15 CVAD insertion surgeries were reviewed. The total average preoperative dose of FVIII was 93.5 IU/kg (range: 53.7-145.4 IU/kg). The total average postoperative dose was 818.7 IU/kg (range: 441-1258 IU/kg). The total perioperative dose was 912.2 IU/kg (range: 495.2-1349 IU/kg). The current study attempts to describe the experience at McMaster Children's Hospital for CVAD insertion surgeries, the average factor dose administered has decreased during the years. These results may be of help in the development of optimal treatment schedules.

    Twentyeight patients with ileofemoral venous thrombosis were treated surgically. Five of the patients had moderate degree of venous congestion, 18 patients had phlegmasia alba dolens and five patients had phlegmasia coerulea dolens. The mean age was 54 years, range 15-80 years, and 15 were men and 13 were women. In all cases the thrombosis was verified by phlebography. Thrombectomy was performed with a Fogarty venous thrombectomy catheter. Peroperative phlebography was used in most cases to guarantee complete extraction of thrombotic material. No operative pulmonary embolism or mortality was encountered. Postoperative continuous heparin infusion in the thrombectomized segment was used for the first week followed by dicumarol treatment. The patients were followed from 6 months to 4 years postoperatively. In two patients thrombectomy was not possible to perform. One of these patients developed a pronounced postthrombotic syndrome, the other developed venous congestion of more moderate degree. Excellent long-term time results were obtained in 82% of the patients and satisfactory in 14%. Thrombectomy is an efficient treatment of ileofemoral venous thrombosis.

    To evaluate the efficacy and safety of radiologic venous port placement in children under venous anesthesia. Between April 2009 and July 2011, 44 ports were implanted in 41 children (24 boys, 17 girls). The age of patients ranged from 9 months to 19 years (mean, 6.5 years) and their body weights ranged from 6.8 kg to 56.3 kg (mean, 23.2 kg). Right internal jugular vein access was used in 42 ports, right subclavian vein in 1, and left subclavian in 1. Durability and complications of port implantation were reviewed. The technical success rate was 100%. The catheter life was 10-661 days (mean 246 days). Two patients died during the follow-up period, 21 and 6 ports were removed at the end of treatment or as a result of complications, respectively. One port was removed and replaced by a Hickmann catheter. Three ports were explanted due to port-related sepsis, one due to a catheter kink, and two for unexplained fever or insertion site pain. The overall port-related infection was 3 cases (6.8%, 0.28/1000 catheter days). Venous port placement by interventional radiologists in children under intravenous sedation is relatively safe, with a high rate of technical success and low rate of complications.

    The objectives are to analyze the technical success rate as well as the short-term and long-term complications of totally implantable venous access ports (TIVAPs) at the forearm. Retrospective analysis of 1,704 consecutively implanted TIVAPs was performed. Primary endpoints were defined as technical success rate, clinical outcome, device service interval, and rates of major complications. Minor complications not requiring port explantation were defined as secondary endpoints. The technical success rate was 99.2 % with no major complications. During follow-up, a total of 643,200 catheter-days were documented, the mean device service interval was 380.6 days/patient. A total of 243 complications (14.4 %) in 226 patients were observed (0.4/1000 catheter-days), in 140 patients (8.3 %) the port device had to be explanted. Disconnection between the port device and the catheter (1.6 %) was more frequent than fracture (0.8 %) and leakage (0.6 %) of the catheter, which occurred more frequently when the catheter was inserted via the cephalic versus the brachial vein. TIVAP implantation at the forearm is a simple and safe procedure with a low rate of early and late complications. (orig.)

  13. A venous outflow method for measurement of rapid changes of the cerebral blood flow and oxygen consumption in the rat.

    Nilsson, B; Siesjö, B K

    1983-01-01

    A technique for continuous measurement of cerebral venous outflow in the rat is described. The method involves cannulation of one retroglenoid vein close to its exit from the skull, and diversion of cerebral venous blood through a closed extracorporal circuit with a drop recording device, the blood being returned to the central venous circulation via a catheter in the external jugular vein. Occlusion of the contralateral retroglenoid vein increases measured flow and minimizes extracerebral contamination of the diverted cerebral venous blood. The venous outflow system is not further isolated from cerebral or potential extracerebral collaterals. Thus, the mass of tissue drained cannot be exactly defined anatomically. However, the experiments involving changes of PP, arterial CO2 tension, and induction of epileptic seizure activity, and simultaneous indirect measurements with radioactive tracer technique, indicate that significant extracerebral contamination does not occur and that in short term measurements the venous outflow represents cerebral blood flow (CBF) in a constant mass of (dorsal and central, mainly forebrain) cerebral tissue. Measurement of arterial blood pressure and pressure in the cisterna magna allows calculation of cerebral perfusion pressure (PP). By simultaneous measurement of arterial and cerebral venous oxygen content changes in cerebral oxygen consumption (CMRO2) can be calculated. The method has been applied to document several situations of transient CBF and CMRO2 changes. PMID:6658967

    Full Text Available INTRODUCTION: Central venous catheters (CVC are devices of great importance in health care. The advantages gained from the use of catheters outweigh the complications that might result from their use, among which bloodstream infections (BSI. In spite of its importance, few national studies have addressed this issue. OBJECTIVE: The aim this study was to determine the incidence of BSI in patients with CVC, hospitalized in ICU, as well as the variables associated with this complication. METHODS: Multicentric cohort study carried out at ICUs of three hospitals at Universidade Federal de São Paulo complex. RESULTS: A total of 118 cases of BSI in 11.546 catheters day were observed: 10.22 BSI per 1,000 catheters day. On average, BSI was associated to seven additional days of hospital stay in our study (p < 0.001, with a significant difference between types of catheters. Concerning the place of insertion, there was no statistical difference in BSI rates. CONCLUSION: We concluded that a patient who uses a catheter for longer than 13 days presents a progressive risk for infection of approximately three times higher in relation to a patient who uses the catheter for less than 13 days (p < 0.001. The median duration of catheter use was 14 days among patients with BSI and 9 days in patients without infection (p < 0.001. There was higher prevalence of Gram-negative infections. The risk factors for BSI were utilization of multiple-lumen catheters, duration of catheterization and ICU length of stay.

    Background Central venous pressure (CVP) and intrathoracic blood volume index (ITBVI) were used to assess the fluid status.It has previously been shown that CVP is not as accurate as ITBVI for all the shock patients.We therefore hypothesized that the change of CVP has the ability to predict fluid responsiveness in some clinical cases of shock.Methods From September 1st 2009 to September 1st 2011,sixty-three patients with shock from different Intensive Care Unit (ICU) were collected into this retrospective study.All the patients received fluid challenge strategy (infusing 300 ml hydroxyethyl starch in 20 minutes),were monitored with CVP and pulse-indicated continuous cardiac output (PICCO).The correlation between changes in cardiac index (△CI),CVP (△CVP) and ITBVI (△ITBVI) were analyzed.Fluid responsiveness was defined as an increase in CI≥10%.Receiver operating characteristic (ROC) curves were generated for △CVP and △ITBVI.Results For all the patients,there was no correlation between △CI and △CVP (P=0.073),but in the subgroup analysis,the correlation between △CI and △CVP was significant in those younger than 60 years old (P=-0.018) and those with hypovolemic shock (P=0.001).The difference of areas under the ROC curves of △CVP and △ITBVI were not statistically significant in the group younger than 60 years old or hypovolemic shock group (P >0.05,respectively).However,no similar results can be found in the group older than 60 years old and the other two shock type groups from ROC curves of △CVP and △ITBVI.Conclusions △CVP is not suitable for evaluating the volume status of the shock patients with fluid resuscitation regardless of their condition.However,in some ways,△CVP have the ability to predict fluid responsiveness in the younger shock patients or in the hypovolemic shock patients.

    Full Text Available Abstract Background Continuous monitoring of central venous oxygen saturation (ScvO2 has been proposed as a prognostic indicator in several pathological conditions, including cardiac diseases, sepsis, trauma. To our knowledge, no studies have evaluated ScvO2 in polytraumatized patients with brain injury so far. Thus, the aim of the present study was to assess the prognostic role of ScvO2 monitoring during first 24 hours after trauma in this patients' population. Methods This prospective, non-controlled study, carried out between April 2006 and March 2008, was performed in a higher level Trauma Center in Florence (Italy. In the study period, 121 patients affected by major brain injury after major trauma were recruited. Inclusion criteria were: 1. Glasgow Coma Scale (GCS score ≤ 13; 2. an Injury Severity Score (ISS ≥ 15. Exclusion criteria included: 1. pregnancy; 2. age 2 monitoring within 2 hours from the trauma. Demographic and clinical data were collected, including Abbreviated Injury Scale (AIS, Injury Severity Score (ISS, Simplified Acute Physiologic Score II (SAPS II, Marshall score. The worst values of lactate and ScvO2 within the first 24 hours from trauma, ICU length of stay (LOS, and 28-day mortality were recorded. Results Patients who deceased within 28 days showed higher age (53 ± 16.6 vs 43.8 ± 19.6, P = 0.043, ISS core (39.3 ± 14 vs 30.3 ± 10.1, P 2 resulted significantly lower (66.7% ± 11.9 vs 70.1% ± 8.9 vs, respectively; P = 0.046. Patients with ScvO2 values ≤ 65% also showed higher 28-days mortality rate (31.3% vs 13.5%, P = 0.034, ICU LOS (28.5 ± 15.2 vs 16.6 ± 13.8, P 2 > 65%. Conclusion ScvO2 value less than 65%, measured in the first 24 hours after admission in patients with major trauma and head injury, was associated with higher mortality and prolonged hospitalization.

    Full Text Available Resumen Introducción y objetivos: Diferentes mecanismos se implican en la captación, transporte, entrega y utilización del oxígeno en los organismos vivos, y cada uno de ellos puede afectarse en el enfermo grave. El propósito de este trabajo fue conocer la confiabilidad de los cálculos especiales de la oxigenación, procedentes de muestras venosas centrales. Método: Se realizó un estudio prospectivo con 22 pacientes a los que se les practicó cirugía cardíaca, en los que se compararon los cálculos especiales obtenidos de muestras venosas centrales con los venosos-mixtos. Resultados: Se encontró correlación estadística significativa entre la diferencia arteriovenosa de oxígeno, el cortocircuito y la saturación venosa de hemoglobina oxigenada. Sin embargo, se halló un bajo por ciento de fiabilidad al aplicarles los criterios protocolizados; pero fue factible mediante ecuaciones de regresión, lograr una corrección altamente significativa (p < 0,01, que elevó la fiabilidad a más del 90 %. Conclusiones: Las muestras venosas centrales constituyen una alternativa recomendable para obtener cálculos especiales de la oxigenación durante la cirugía cardíaca. / Abstract Introduction and Objectives: Different mechanisms are involved in the uptake, transportation, delivery and utilization of oxygen in living organisms, and each of them may be affected in the severely ill patient.

    Full Text Available Abstract Background Tunnelled central venous dialysis catheter use is significantly limited by the occurrence of catheter-related infections. This randomised controlled trial assessed the efficacy of a 48 hour 70% ethanol lock vs heparin locks in prolonging the time to the first episode of catheter related blood stream infection (CRBSI. Methods Patients undergoing haemodialysis (HD via a tunnelled catheter were randomised 1:1 to once per week ethanol locks (with two heparin locks between other dialysis sessions vs thrice per week heparin locks. Results Observed catheter days in the heparin (n=24 and ethanol (n=25 groups were 1814 and 3614 respectively. CRBSI occurred at a rate of 0.85 vs. 0.28 per 1000 catheter days in the heparin vs ethanol group by intention to treat analysis (incident rate ratio (IRR for ethanol vs. heparin 0.17; 95%CI 0.02-1.63; p=0.12. Flow issues requiring catheter removal occurred at a rate of 1.6 vs 1.4 per 1000 catheter days in the heparin and ethanol groups respectively (IRR 0.85; 95% CI 0.20-3.5 p =0.82 (for ethanol vs heparin. Conclusions Catheter survival and catheter-related blood stream infection were not significantly different but there was a trend towards a reduced rate of infection in the ethanol group. This study establishes proof of concept and will inform an adequately powered multicentre trial to definitively examine the efficacy and safety of ethanol locks as an alternative to current therapies used in the prevention of catheter-associated blood stream infections in patients dialysing with tunnelled catheters.

    Full Text Available Background and Objective: The assessment of blood volume is now one of the most commonly needed interventions in the first line of care and severe ill patients. Measuring central venous pressure (CVP is an invasive method, most frequently used in clinical practice for the assessment of volume status. The di-ameter of the inferior vena cava (IVC is a parameter to estimate central venous pressure. The purpose of this study was to determine whether measurement of the anterior-posterior diameter of the IVC by ultra-sonography, correlates with CVP. Materials and Methods: It was a descriptive and pro-spective study on 50 patients; CVP was measured in supine position by CVP manometer. Anterior – pos-terior IVC diameter was assessed by ultrasonography during inspiration and expiration. Results: The mean of CVP during inspiration and ex-piration was 11.31+5.59, 12.20 + 5.65cmH2o, respec-tively. The mean of inspiratory and expiratory IVC diameter was 7.71+3.56, 11.97+3.28 mm, respectively. There was significant relation between CVP and IVC diameter in the inspiration (r=0.664, p<0.0001 and expiration (r=0.495, p=0.001. The relation between these two variables was linear. Conclusion: Result of this study showed that IVC di-ameter measurement by ultrasonography can be used to estimate the mean of CVP.

    Accidental subclavian artery cannulation is an uncommon but potentially serious complication of central venous catheterization. Removal of a catheter inadvertently placed in the subclavian artery can lead to substantial bleeding, as achieving hemostasis in this area through manual compression presents considerable difficulty. Additionally, surgical treatment might be unsuitable for high-risk patients due to comorbidities. Here, we report a case of an inadvertently-inserted 11.5-French hemodialysis catheter in the subclavian artery during internal jugular venous catheterization. We performed percutaneous closure of the subclavian artery using three 6-French Perclose Proglide® devices with a balloon tamponade in the proximal part of the subclavian artery. Closure was completed without embolic neurological complications. PMID:27482271

    Pseudozyma spp are amorphic yeasts. They are commonly plant pathogens, but rarely cause invasive fungal disease in humans. Only three cases of central venous catheter (CVC)-associated blood stream infections due to this organism have been reported in the literature. Main underlying risk factors for Pseudozyma spp infection are bowel surgery, CVC and total parenteral nutrition. We present a rare case of Pseudozyma spp catheter-associated blood stream infection that was successfully treated with antifungal therapy and removal of CVC. It is important to recognise and differentiate this species from other yeasts as it may require the use of amphotericin B or voriconazole instead of fluconazole, to which the organism is variably resistant.
