  3. Anatomical basis of central venous catheter fracture.

    2008-03-01

    Central venous catheter fracture is a rare complication of long-term indwelling subclavian venous access. Subclavian vein access has been the recommended approach for placing central venous catheters. The anatomical landmark method for subclavian access remains a highly successful and nonequipment-dependent method for rapid central access. More recently, the internal jugular vein approach has emerged as the preferred route for long-term central venous access. However, variations in internal jugular vein anatomy make the landmark method less reliable. Use of two-dimensional real-time ultrasound during internal jugular vein access is associated with better success, a lower complication rate, and faster access. A case of central venous catheter fracture initiated an internal review of long-term central venous access procedures. We have converted to a predominantly internal jugular vein approach. This case report and literature review may assist other physicians and institutions in re-evaluating long-term central venous access protocols.

    Background Long-term central venous catheters have improved the quality of care for patients with chronic illnesses, but are complicated by obstructions which can result in delay of treatment or catheter removal. Design and Methods This paper reviews thrombolytic treatment for catheter obstruction. Literature from Medline searches using the terms “central venous catheter”, “central venous access device” OR “central venous line” associated with the terms “obstruction”, “occlusion” OR “thrombolytic” was reviewed. Efficacy of thrombolytic therapy, central venous catheter clearance rates and time to clearance were assessed. Results Alteplase, one of the current therapies, clears 52% of obstructed catheters within 30 min with 86% overall clearance (after 2 doses, when necessary). However, newer medications may have higher efficacy or shorter time to clearance. Reteplase cleared 67–74% within 30–40 min and 95% of catheters overall. Occlusions were resolved in 70 and 83% of patients with one and 2 doses of tenecteplase, respectively. Recombinant urokinase cleared 60% of catheters at 30 min and 73% overall. Alfimeprase demonstrated rapid catheter clearance with resolution in 40% of subjects within 5 min, 60% within 30 min, and 80% within 2 h. Additionally, urokinase prophylaxis decreased the incidence of catheter occlusions from 16–68% in the control group to 4–23% in the treatment group; in some studies, rates of catheter infections were also decreased in the urokinase group. Conclusions Thrombolytic agents successfully clear central venous catheter occlusions in most cases. Newer agents may act more rapidly and effectively than currently utilized therapies, but randomized studies with direct comparisons of these agents are needed to determine optimal management for catheter obstruction.

    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.

    Many of the risks associated with central venous access are well recognized. We report a case of inadvertent lymphatic disruption during the insertion of a tunneled central venous catheter in a patient with raised left and right atrial pressures and severe pulmonary hypertension, which led to significant hemodynamic instability. To our knowledge, this rare complication is previously unreported.

    The inappropriate placement of a patient's central venous catheter in the pleural space by the serendipitous injection of Tc-99m labeled red blood cells through the catheter during a GI bleeding study was discovered. Position and patency of central venous lines can be incidentally evaluated by using existing central venous catheters for administration of radiopharmaceuticals during radionuclide imaging studies.

    2010-01-01

    The majority of nosocomial bloodstream infections in critically ill patients originate from an infected central venous catheter (CVC). Catheter-related bloodstream infections (CRBSIs) cause significant morbidity and mortality and increase the cost of care. The most frequent causative organisms for CRBSI are coagulase-negative staphylococci (CoNSs), Staphylococcus aureus, enterococci, and Candida species. The path to infection frequently includes migration of skin organisms at the insertion site into the cutaneous catheter tract, resulting in microbial colonization of the catheter tip and formation of biofilm. Evidence-based strategies for the prevention of CRBSI include behavioral and educational interventions, effective skin antisepsis coupled with maximum barrier precautions, the use of antiseptic dressings, and the use of antiseptic or antibiotic impregnated catheters. Achieving and maintaining very low rates of CRBSI requires a multidisciplinary approach involving the entire health care team, the use of novel technologies in patients with the highest risk of CRBSI, and frequent reeducation of staff.

    2007-01-01

    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.

    The insertion of central venous catheters is a common bedside procedure performed in intensive care units. Here, we present a case of an 82-year-old man who underwent insertion of a central venous catheter in the internal jugular vein without perceived complications. Postprocedural radiographs showed rostral migration of the catheter, and computed tomography performed coincidentally showed cannulation of the jugular bulb at the level of the jugular foramen. To our knowledge, this is the first report to document migration of a central venous catheter from the internal jugular vein into the dural sinuses, as confirmed by computed tomography. The case highlights the importance of acquiring postprocedural radiographs for all insertions of central venous catheters to confirm catheter placement.

    The placement of central venous catheter (CVC) through internal jugular vein is not free from potential hazards. We report two cases of triple lumen central venous catheter, placed into right internal jugular vein, which got entrapped in patients who had undergone mitral valve replacement. The entrapment of catheter went unnoticed until the time of removal. Subsequent investigations, mechanism of entrapment, prevention, and removal is described. To conclude, we encountered an unusual cause of stuck central venous catheter, in the left atrial suture line. Removal of central venous catheter requires utmost care, and should never be done by forceful traction in the postoperative cardiac surgical patients, as it may lead to disruption of suture lines or rupture of vessels.

    The use of central venous catheters (CVCs) in children is escalating, which is likely linked to the increased incidence of pediatric venous thromboembolism (VTE). In order to better understand the specific risk factors associated with CVC-VTE in children, as well as available prevention methods, a literature review was performed. The overall incidence of CVC-VTE was found to range from 0 to 74%, depending on the patient population, CVC type, imaging modality, and study design. Throughout the available literature, there was not a consistent determination regarding whether a particular type of central line (tunneled vs. non-tunneled vs. peripherally inserted vs. implanted), catheter material, insertion technique, or insertion location lead to an increased VTE risk. The patient populations who were found to be most at risk for CVC-VTE were those with cancer, congenital heart disease, gastrointestinal failure, systemic infection, intensive care unit admission, or involved in a trauma. Both mechanical and pharmacological prophylactic techniques have been shown to be successful in preventing VTE in adult patients, but studies in children have yet to be performed or are underpowered. In order to better determine true CVC-VTE risk factors and best preventative techniques, an increase in large, prospective pediatric trials needs to be performed. PMID:28168186

    2009-08-01

    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.

    Purpose. The purpose of this study was to evaluate radiological-interventional central venous port catheter corrections in migrated/malpositioned catheter tips. Materials and Methods. Thirty patients with migrated/malpositioned port catheter tips were included in this retrospective analysis. To visualize the catheter patency a contrast-enhanced port catheter series was performed, followed by transfemoral port catheter correction with various 5-F angiographic catheters (pigtail; Sos Omni), gooseneck snares, or combinations thereof. Results. One patient showed spontaneous reposition of the catheter tip. In 27 of 29 patients (93%), radiological-interventional port catheter correction was successful. In two patients port catheter malposition correction was not possible, because of the inability to catch either the catheter tip or the catheter in its course, possibly due to fibrin sheath formation with attachment of the catheter to the vessel wall. No disconnection or port catheter dysfunction was observed after correction. Conclusions. We conclude that in migrated catheter tips radiological-interventional port catheter correction is a minimally invasive alternative to port extraction and reimplantation. In patients with a fibrin sheath and/or thrombosis port catheter correction is often more challenging.

    The purpose of this review is to explore the pathophysiology, epidemiology, and interventional treatment of central vein stenosis (CVS) that may result from central vein catheter (CVC) placement. The precise mechanism of CVC-associated CVS remains largely undefined, though anatomic considerations appear to play a prominent pathologic role. The impact of CVC-associated CVS on arteriovenous fistula outcomes is reviewed. The percutaneous treatment of CVS, observation, angioplasty, or angioplasty with stent placement is reviewed, along with potential surgical treatment options. As the treatment outcomes of CVC-associated CVS have been disappointing, catheter avoidance remains the best strategy.

    Placement of a central venous catheter is one of the most common invasive procedures and is associated with septic and mechanical complications, such as bleeding and pneumothorax. Up to 30% of attempts to cannulate the central vein fail. Correct positioning of the patient can help to maximise the success rate. For placement of catheters in the subclavian vein, patients should be in the Trendelenburg position without the use of a shoulder roll to retract the shoulders. Traditionally, central venous catheters are placed using a 'blind' technique that relies on external anatomical reference marks to localise the vein. However, unnoticed anatomical variations or central venous thrombosis may contribute to cannulation failure with this technique. The use of ultrasound has been shown to increase the success rate and avoid mechanical complications when placing a catheter in the internal jugular vein. It may also increase the success rate in subclavian vein catheterisation. To increase patient safety, the use of ultrasound when placing a central venous catheter should be embraced and become the standard of care.

This article discusses one area, the incidence of central venous catheter-related bloodstream infection in acute care, to examine the available evidence and identify ways in which this evidence can be applied to practice. Research indicates that implementing best practice at the time of insertion is a principal determinant in minimising the risk of catheter-related bloodstream infection.

    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.

    The central venous catheter (CVC) is a catheter placed into a large vein in the neck [internal jugular vein (IJV)], chest (subclavian vein or axillary vein) or groin (femoral vein). There are several situations that require the insertion of a CVC mainly to administer medications or fluids, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure. CVC usually remain in place for a longer period of time than other venous access devices. There are situations according to the drug administration or length of stay of the catheter that specific systems are indicated such as; a Hickman line, a peripherally inserted central catheter (PICC) line or a Port-a-Cath may be considered because of their smaller infection risk. Sterile technique is highly important here, as a line may serve as a port of entry for pathogenic organisms, and the line itself may become infected with organisms such as Staphylococcus aureus and coagulase-negative Staphylococci. In the current review we will present the complication of pneumothorax after CVC insertion.

    The objective of this prospective observational study was to determine the influence of femoral and central internal jugular venous catheters on the incidence of catheter-related bacteremia (CRB). We included patients admitted to a 12-bed polyvalent medico-surgical intensive care unit over 4 years who received one or more femoral or central internal jugular venous catheters. We diagnosed 16 cases of CRB in 208 femoral catheters and 22 in 515 central internal jugular venous catheters. We found a higher incidence of CRB with femoral (9.52 per 1,000 catheter days) than with central internal jugular venous access (4.83 per 1,000 catheter days; risk ratio = 1.93; 95% confidence interval: 1.03-3.73; P = 0.04). Central internal jugular venous access could be considered a safer route of venous access than femoral access in minimizing the risk of central venous catheter-related bacteremia.

    Despite the level of skill of the operator and the use of ultrasound guidance, central venous catheter (CVC) placement can result in CVC malpositioning, an unintended placement of the catheter tip in an inadequate vessel. CVC malpositioning is not a complication of central line insertion; however, undiagnosed CVC malpositioning can be associated with significant morbidity and mortality. The objectives of this review were to describe factors associated with intravascular malpositioning of CVCs inserted via the neck and chest and to offer ways of preventing, identifying, and correcting such malpositioning. A literature search of PubMed, Cochrane Library, and MD Consult was performed in June 2014. By searching for "Central line malposition" and then for "Central venous catheters intravascular malposition," we found 178 articles written in English. Of those, we found that 39 were relevant to our objectives and included them in our review. According to those articles, intravascular CVC malpositioning is associated with the presence of congenital and acquired anatomical variants, catheter insertion in left thoracic venous system, inappropriate bevel orientation upon needle insertion, and patient's body habitus variants. Although plain chest radiography is the standard imaging modality for confirming catheter tip location, signs and symptoms of CVC malpositioning even in presence of normal or inconclusive conventional radiography findings should prompt the use of additional diagnostic methods to confirm or rule out CVC malpositioning. With very few exceptions, the recommendation in cases of intravascular CVC malpositioning is to remove and relocate the catheter. Knowing the mechanisms of CVC malpositioning and how to prevent, identify, and correct CVC malpositioning could decrease harm to patients with this condition.

    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.

    Summary Background 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. Material/Methods 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. Results CVC malposition was detected with different imaging modalities followed by appropriate medical procedures. Conclusions 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. PMID:25177409

    2017-01-01

    Suprapubic catheterization is an alternative method for urinary drainage that is used when transurethral catheterization fails. Traditionally, inserted large-bore suprapubic catheters may cause fatal complications. During the past decade, we used a small central venous catheter (CVC) suprapubicly in 16 male patients for the purpose of urinary drainage, when transurethral catheterization failed. The procedure is performed in no more than 10 minutes. Success rate was 100% and this approach did not lead to any complications. In conclusion, placing a CVC for suprapubic drainage is a safe method with a high success rate and we recommend it in patients with failed transurethral catheterization after a few attempts (2-3 attempts).

  12. Misplaced central venous catheters: applied anatomy and practical management.

    PubMed

    2013-03-01

    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'.

    The placement of a central venous catheter remains an important intervention in the care of critically ill patients in the emergency department. We propose an ultrasound-first protocol for 3 aspects of central venous catheter placement above the diaphragm: dynamic procedural guidance, evaluation for pneumothorax, and confirmation of the catheter tip location.

    Central venous catheterization represents a significant medical advancement, particularly in the treatment of critical ill. However, there is a high risk of central venous catheters-related infection. A novel antiseptic central venous catheter, made of polyurethane and impregnated with chlorhexidine and silver sulfadiazine, was developed to reduce the risk of catheters-related infection. In this study, we did a randomized clinical study to determine the efficacy by using antiseptic catheters for the prevention of central venous catheters-related infection in the intensive care units. A total of 204 patients with 235 central venous catheters were studied at the surgical intensive care units at National Taiwan University Hospital between November 1998 and June 1999. Participants received either a standard triple-lumen polyurethane catheter or an antiseptic catheter (Arrow International, Reading, Pennsylvania, USA). Both were indistinguishable from each other. Compared to standard polyurethane catheters, antiseptic catheters were less likely to be colonized by microorganisms when they were cultured at the removal (8.0 versus 20.0 colonized catheters per 100 catheters; relative risk 0.34 [95% CI, 0.15 to 0.74]; p<0.01). There was no significant differences between both groups in catheter-related infections (0.9 versus 4.9 infections per 100 catheters; relative risk 0.17 [95% CI, 0.03 to 1.15]; p = 0.07). Gram-positive cocci and fungi were more likely to colonize in the standard polyurethane catheters (p = 0.06 and 0.04, compared to antiseptic catheters respectively). Two of our cases in the control group died directly due to catheter-related candidemia. No adverse reactions such as hypersensitivity or leukopenia were found in the antiseptic catheter group. Our study showed that central venous catheters with antiseptic coating were safe and had less risk of colonization of bacteria and fungi than standard catheters in the critically ill patients.

  15. Heparin Leakage in Central Venous Catheters by Hemodynamic Transport

    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 (<10s), advection-dominated phase that rapidly depletes the concentration of heparin at the CVC tip, followed by a slow, diffusion-limited phase inside the 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.

    The Peripherally Inserted Central Catheter (PICC) has been used as a safe venous access for infants at risk. The aim of this study was to describe the knowledge and practice of nurses from the five public Neonatal Intensive Care Units, of Recife-PE, Brazil, about the use of the PICC. The sample was comprised by 52 nurses; data were collected from January to February/2010. It was found that 64,8% of nurses did not have license for insertion of the PICC. Only two units routinely used the PICC. About the indication of the access, the accuracy was above 70%. In unit B only 8,3% of nurses reported adequate initial location of the catheter tip. It was concluded that is necessary greater incentives to train nurses to use the PICC.

    Suprapubic catheterization is an alternative method for urinary drainage that is used when transurethral catheterization fails. Traditionally, inserted large-bore suprapubic catheters may cause fatal complications. During the past decade, we used a small central venous catheter (CVC) suprapubicly in 16 male patients for the purpose of urinary drainage, when transurethral catheterization failed. The procedure is performed in no more than 10 minutes. Success rate was 100% and this approach did not lead to any complications. In conclusion, placing a CVC for suprapubic drainage is a safe method with a high success rate and we recommend it in patients with failed transurethral catheterization after a few attempts (2–3 attempts).

    Antibiotic lock therapy (ALT) is an adjunctive procedure to prevent or treat central venous catheter infections, ensuing catheter-related bacteremia, and catheter-related metastatic infections. Daptomycin is a cyclic lipopeptide that is rapidly bactericidal against methicillin-susceptible and -resistant Staphylococcus aureus. The efficacies of daptomycin against central venous catheter biofilms, catheter-related bacteremia, and catheter-related metastatic infections were evaluated by adapting a previously reported central venous catheter biofilm model in rats. Combined daptomycin ALT and systemic dosing resulted in the clearance of an established in vivo S. aureus central venous catheter biofilm after just two daily ALT treatments (30 min with daptomycin at 5 mg/ml) with concurrent systemic daptomycin dosing (40 mg/kg of body weight/day subcutaneously [s.c.]; equivalent exposure of 6 mg/kg/day in people). Daptomycin ALT solutions formulated in either saline or lactated Ringer's solution were equally fast in eradicating established in vivo methicillin-resistant Staphylococcus epidermidis (MRSE) central venous catheter biofilms. However, the lactated Ringer's formulation was superior to that of saline in sustaining the bacterial clearance of treated central venous catheters (83% versus 50%). In MRSE-infected central venous catheter studies, 3 days of daptomycin or vancomycin ALT (18 h at 5 mg/ml) with systemic s.c. dosing (40 mg/kg/day daptomycin or 100 mg/kg/day vancomycin) was equally effective 1 week posttherapy in maintaining cleared central venous catheters (90% [n = 10] versus 100% [n = 8]). These results suggest that daptomycin ALT, along with systemic dosing, could be an effective treatment option for the prevention or eradication of staphylococcal central venous catheter biofilm infections, thereby reducing the occurrence of catheter-related bacteremia or catheter-related metastatic infections.

    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.

    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.

  1. Prevention of central venous catheter-related infection: update.

    PubMed

    Casey, Anna L; Elliott, Tom S J

    Central venous catheters (CVCs) are an essential part of modern-day healthcare, but infections associated with these devices continue to cause significant morbidity and mortality. There are many approaches for the prevention of CVC-related infection and these are outlined in national guidelines. The Department of Health Saving Lives campaign has developed a care-bundle for the prevention of CVC-related infections that focuses on the fundamental actions to be undertaken during the catheter insertion process and ongoing care. If the rate of catheter-related infection remains high despite the implementation of these infection prevention strategies, the use of novel antimicrobial technologies and practices may be considered. These include CVCs that contain antimicrobial agents, such as antiseptics or antibiotics, needleless intravenous (IV) access devices coated with silver and/or chlorhexidine, IV dressings incorporating chlorhexidine, and the use of antimicrobial catheter lock solutions, such as antibiotics, chelators or ethanol. This article outlines the different types of CVCs available, the risk of infection associated with their use and established and novel measures for prevention of these infections.

    Therapeutic and donor apheresis requires adequate vascular access to achieve inlet flow rates of ∼50-100 mL/min. While central dialysis-type venous catheters can usually provide such access, their use includes several associated risks. Some of these risks can be avoided or diminished if adequate peripheral venous access can be established. Some patients have adequate peripheral veins for apheresis that cannot be readily identified visually or by palpation. We hypothesized that ultrasound-guided peripheral venous access would benefit such patients and would lead to placement of fewer central venous catheters. The technique of ultrasound-guided peripheral access for apheresis has been in use at Houston Methodist Hospital since 2012. We performed a prospective review of patients undergoing inpatient and outpatient apheresis at Houston Methodist Hospital from July 1, 2015 to September 30, 2015, to assess its benefit. During this time, we performed 831 procedures on 186 patients, including 787 therapeutic plasma exchanges, three red blood cell exchanges, 41 peripheral stem cell collections. Ultrasound-guided vascular access was used for 68 procedures (8% of all procedures), including 62 therapeutic plasma exchanges, 4 peripheral stem cell collections, and 2 red blood cell changes. Use of ultrasound-guided peripheral access prevented the placement of central venous catheters in 37 (20%) patients, demonstrating its utility in a busy transfusion service.

    Thirty-one patients with suspected central venous catheter-related bacteremia were evaluated with comparative quantitative cultures of central venous and peripheral blood specimens. Using criteria developed from studies in bacteremic animals, 19 patients were confirmed to have catheter-related bacteremia. Antibiotic therapy was administered through the catheter (in situ therapy) in 17 of those patients to evaluate the feasibility of treating patients with true central venous catheter-related bacteremias without catheter removal. Bacteremia was successfully eradicated in 11 of 17 patients (65%), allowing 7 patients to retain their catheter a median of 157 days. This study validates the use of comparative quantitative blood cultures in the diagnosis of catheter-related bacteremia and indicates that in situ therapy is a rational alternative to catheter removal in patients with catheter-related bacteremia.

    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.

    The use of central venous catheters (CVCs) represents an important step in the management of the surgical, onco-hematology and critically ill patients. CVCs in neonates, like in adult patients, are mainly used to infuse hyperosmolar solutions, to take blood samples and for hemodynamic monitoring. The need for CVCs is higher in neonates than in adults. Poor peripheral access and the high demand for IV access and blood samples are already valuable indications for a CVC.

    Background Bacillus organisms are common laboratory contaminants. The majority of Bacillus bacteraemias are transient and not clinically significant. Clinically significant infection due to Bacillus species is rare and mostly due to Bacillus cereus infections in immuno-compromised hosts. Case presentation We report a case of central venous catheter infection with Bacillus pumilus in an immunocompetent child with tufting enteropathy on long-term parenteral nutrition (PN). There were three episodes of central venous catheter infection with Bacillus pumilus in three months. Despite adequate and appropriate use of intravenous antibiotics, the infection failed to clear resulting in the need for removal of the catheter for complete cure. Conclusion Bacillus species can cause clinically significant central venous catheter infection, even in an immunocompetent host. Despite adequate antibiotic treatment, the central venous catheter may need removal for complete cure. PMID:17967173

    Central venous access is an important aspect of neonatal intensive care management. Malpositioned central catheters have been reported to induce cardiac tachyarrhythmia in adult populations and there are case reports within the neonatal population. We present a case of a preterm neonate with a preexisting umbilical venous catheter (UVC), who then developed a supraventricular tachycardia (SVT). This was initially treated with intravenous adenosine with transient reversion. Catheter migration was subsequently detected, with the UVC tip located within the heart. Upon withdrawal of the UVC and a final dose of adenosine, the arrhythmia permanently resolved. Our literature review confirms that tachyarrhythmia is a rare but recognised neonatal complication of malpositioned central venous catheters. We recommend the immediate investigation of central catheter position when managing neonatal tachyarrhythmia, as catheter repositioning is an essential aspect of management. PMID:28058050

    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.

    A 5 year old girl with ASD was scheduled for open heart surgery. A central venous catheter was placed via the right infraclavicular vein after induction of anesthesia. Thirty minutes after insertion of the catheter, a decrease in arterial pressure and pulse pressure, an increase in heart rate and central venous pressure were observed. Cardiac tamponade was revealed by rapid opening of the chest. Gushing blood out of a hole in the right ventricular free wall was confirmed by pericardiotomy. The hemodynamics were stabilized by blood transfusion and surgical closure of the hole on the ventricle. This perforation was thought to be caused by careless insertion of a relatively stiff central venous catheter.

    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.

    Central venous catheters are used in various hospital wards. An anterior-posterior chest X-ray is usually obtained soon after cannulation to assess the location of the catheter tip. This prospective clinical study was designed to determine the radiographic catheter tip position after central venous cannulation by various routes, to identify clinical problems possibly associated with the use of malpositioned catheters and to make a cost-benefit analysis of routine chest X-ray with respect to catheter malposition. A total 1619 central venous cannulations were recorded during a three-year period with respect to patient data, information about the cannulation procedures, the radiographic catheter positions and complications during clinical use. The total incidence of radiographic catheter tip malposition, defined as extrathoracic or ventricular positioning, was 3.3% (confidence interval 25 to 4.3%). Cannulation by the right subclavian vein was associated with the highest risk of malposition, 9.1%, compared with 1.4% by the right internal jugular vein. Six of the 53 malpositioned catheters were removed or adjusted. No case of malposition was associated with vascular perforation, local venous thrombosis or cerebral symptoms. We conclude that the radiographic incidence of central venous catheter malpositioning is low and that clinical use of malpositioned catheters is associated with few complications. However, determination of the catheter position by chest X-ray should be considered when mechanical complications cannot be excluded, aspiration of venous blood is not possible, or the catheter is intended for central venous pressure monitoring, high flow use or infusion of local irritant drugs.

During 1997 central venous catheter type Hickman was used in nine children between two and half to eleven years old (average six years and one months). The average time of catheter placement was six months, in two cases catheter were eliminated after two and three months respectively since application (spontaneous elimination and repeated septic attacks, caused bu resistant bacterial strains). Gram-positive bacteria have been isolated with eight children (Staphylococcus aureus and Staphylococcus epidermidis), and gram-negative enterobacteriaceae (Serratia marcescens, Pseudomonas aeruginosa, Klebsiella oxytocia and pneumoniae, Escherichia coli, Salmonella group C and Enterococcus faecalis) in samples taken from the catheter and hemoculture. The central venous catheter is useful in treating oncological patients, but may cause serious consequences, like local infections or septicaemia.

    To evaluate the risk factors associated with an increased risk of symptomatic peripherally inserted central venous catheter (PICC)-related venous thrombosis. Retrospective analyses identified 2313 patients who received PICCs from 1 January 2012 to 31 December 2013. All 11 patients with symptomatic PICC-related venous thrombosis (thrombosis group) and 148 who did not have thromboses (non-thrombosis group) were selected randomly. The medical information of 159 patients (age, body mass index (BMI), diagnosis, smoking history, nutritional risk score, platelet count, leucocyte count as well as levels of D-dimer, fibrinogen, and degradation products of fibrin) were collected. Logistic regression analysis was undertaken to determine the risk factors for thrombosis. Of 2313 patients, 11 (0.47%) were found to have symptomatic PICC-related venous thrombosis by color Doppler ultrasound. Being bedridden for a long time (odds ratio [(OR]), 17.774; P=0.0017), D-dimer >5 mg/L (36.651; 0.0025) and suffering from one comorbidity (8.39; 0.0265) or more comorbidities (13.705; 0.0083) were the major risk factors for PICC-catheter related venous thrombosis by stepwise logistic regression analysis. Among 159 patients, the prevalence of PICC-associated venous thrombosis in those with ≥1 risk factor was 10.34% (12/116), in those with ≥2 risk factors was 20.41% (10/49), and in those with >3 risk factors was 26.67% (4/15). Being bedridden >72 h, having increased levels of D-dimer (>5 mg/L) and suffering from comorbidities were independent risk factors of PICC-related venous thrombosis.

    Central venous occlusion in children is a challenging problem that can occur after a central venous catheter insertion. Long-term catheter-related complications include sepsis and venous thrombosis with consequent loss of central access. We describe 2 cases of children younger than 1 year who were dependent on a central venous catheter for total parenteral nutrition. They developed a chronic extensive obstruction of the right and left brachiocephalic veins with a superior vena cava syndrome. The patients' survival was dependent on the restoration of central venous access until the planned intestinal transplantation could be performed. Retrograde recanalization of the superior vena cava was successfully achieved using a pathway created under general anesthesia from the femoral vein to, respectively, the right thyroid vein and the right subclavian vein.

    The aim of this study was to investigate the in vitro and in vivo efficacy and the tissue reaction of an antibiofilm coating composed of xylitol, triclosan, and polyhexamethylene biguanide. The antimicrobial activity was analyzed by a turbidimetric method. Scanning electron microscopy was used to evaluate the antiadherent property of central venous catheter (CVC) fragments impregnated with an antibiofilm coating (I-CVC) in comparison with noncoated CVC (NC-CVC) fragments. Two in vivo assays using subcutaneous implantation of NC-CVC and I-CVC fragments in the dorsal area of rats were performed. The first assay comprised hematological and microbiological analysis. The second assay evaluated tissue response by examining the inflammatory reactions after 7 and 21 days. The formulation displayed antimicrobial activity against all tested strains. A biofilm disaggregation with significant reduction of microorganism's adherence in I-CVC fragments was observed. In vivo antiadherence results demonstrated a reduction of early biofilm formation of Staphylococcus aureus ATCC 25923, mainly in an external surface of the I-CVC, in comparison with the NC-CVC. All animals displayed negative hemoculture. No significant tissue reaction was observed, indicating that the antibiofilm formulation could be considered biocompatible. The use of I-CVC could decrease the probability of development of localized or systemic infections.

    In a intensive care unit (ICU) there are many factors that can lead to the occurrence of adverse events. A high percentage of these events are associated with the administration of drugs. Diagnostic tests, such as computed tomography, is common in critically ill patients and technique can be performed with injection of contrast agent to enhance the visualization of soft tissue. The contrast is a medication and the nurse is responsible for its proper administration. The management of the critically ill patient is complex. ICU team and radiology shares responsibility for the care and safety of the patient safety during the transfer and performing tests with contrast. The World Health Organisation patient safety strategies, recommends analysing errors and learning from them. Therefore, it was decided to investigate the causes of the category E severity adverse events that occurred in a patient who was admitted to the ICU for septic shock of abdominal origin. An abdominal computed tomography was performed with contrast which was injected through a central venous catheter. The contrast did not appear in the image. What happened? Causal analysis helped to understand what triggered the event. A care plan and an algorithm were drafted to prevent it from happening again, with the following objectives: improving knowledge, skills and promoting positive attitudes towards patient safety, working at primary, secondary and tertiary care levels.

    This study was designed to evaluate the usefulness of central venous access via the external jugular vein (EJV) employing Groshong catheters, and to compare the complications with those of conventional internal jugular venous catheterization. Central venous access was achieved by insertion of a single-lumen 4.0 Fr Groshong catheter via the EJV or internal jugular vein (IJV) with a single puncture. Complications associated with insertion and central venous catheter-related bloodstream infection (CVC-RBSI) were evaluated from the database. Two hundred and twenty-five patients received 400 catheters for a total period of 5377 catheter-days. Ninety-six patients underwent 201 internal jugular venous catheter (IJV-C) procedures for 2381 catheter-days, and 129 patients underwent 199 external jugular venous catheter (EJV-C) procedures for 2996 catheter-days. Use of EJV-C was associated with a longer catheter insertion length (p < .01) and period (p < .01), a larger number of operations (p < .01), and more frequent use of total parenteral nutrition (TPN) (p < .01) and less frequent use of chemotherapy (p < .01) than for IJV-C. However, there were no significant differences (NS) in complications associated with insertion and CVC-RBSI between IJV-C and EJV-C. There were no significant differences such complications as malposition, oozing or hematoma formation of insertion site, arterial bleeding, nerve damage, pneumothorax, and phlebitis between IJV-C and EJV-C. Moreover, EJV-C was not associated with morbidities such as pneumothorax, arterial bleeding, and nerve damage. Thus the study concluded that EJV-C using Groshong catheters has no severe complications and has the same rates of CVC-RBSI as conventional IJV-C for central venous access.

    Purpose: Central venous catheters (CVC) may fail for many reasons, though 'fibrin sheaths' blocking catheter ports are usually implicated. We examined the sheaths removed from dialysis catheters to determine their histopathology.Methods: Ten catheter strippings were performed and the removed material was studied grossly and microscopically.Results: The histologic specimens showed thrombus both with and without a proteinaceous sheath.Conclusion: Dialysis catheters fail because of thrombus formation. This can occur in either the absence or presence of a protein coating on the catheter, the so-called 'fibrin sheath.'.

    Eighty used and 20 new silicone, polyurethane and polyvinylchloride central venous catheters were tested to establish the Young's modulus and the bending stiffness of the catheters and their introducers. The catheters were subjected to longitudinal traction forces and their lengthening measured. Young's modulus and the geometric moment of inertia were then calculated. It is shown that polyurethane catheters show least variation in their elastic characteristics, and that silicone catheters offer least resistance to bending and do not change their elastic properties after use. All catheters were equally unlikely to cause thrombus production if this is related to excessive bending stiffness.

To collect data in Brazilian and international databases were used the key word bundle and the descriptors catheter-related infection, infection control and central venous catheterization, resulting in fifteen articles, after inclusion criteria application. This work showed five interventions as those commonly employed in the bundles methods: hand hygiene, chlorhexidine gluconate for skin antisepsis, use of maximal sterile barrier precaution during the catheter insertion, avoid the femoral access and daily review of catheter necessity with prompt removal as no longer essential. The majority of the studies showed a significant reduction in bloodstream infection related to or associated with central venous catheters.

    Patients with central venous catheters (CVCs) are at increased risk of bloodstream infections and sepsis-related death. CVC-related bloodstream infections (CRBSIs) are costly and account for a significant proportion of hospital-acquired infections. The aim of this audit was to assess current practice and staff knowledge of CVC post-insertion care and therefore identify aspects of CVC care with potential for improvement. We conducted a prospective audit over 28 consecutive days at a university teaching hospital investigating current practice of CVC post-insertion care in wards with high CVC usage. A multiple choice questionnaire on best practice of CVC insertion and care was distributed among clinical staff. Rates of breaches in catheter care and CRBSIs were calculated and statistical significance assumed when P<0.05. Data was recorded from 151 CVCs in 106 patients giving a total of 721 catheter days. In all, 323 breaches in care were identified giving a failure rate of 44.8%, with significant differences between intensive care unit (ICU) and non-ICU wards (P<0.001). Dressings (not intact) and caps and taps (incorrectly placed) were identified as the major lapses in CVC care with 158 and 156 breaches per 1000 catheter days, respectively. During the study period four CRBSIs were identified, producing a CRBSI rate of 5.5 per 1000 catheter days (95% confidence interval: 0.12-10.97). There are several opportunities to improve CVC post-insertion care. Future interventions to improve reliability of care should focus on implementing best practice rather than further education.

    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.

    More than 2.1 million central venous catheters are placed annually. While carotid artery cannulation is rare, its effects can be devastating. Anesthesia providers frequently work with central venous catheters in the perioperative setting. Therefore, it is imperative that they be able to identify and react appropriately to carotid artery injury both in preexisting central lines and those that they have placed. This case report details a case of accidental carotid artery catheterization during attempted right internal jugular vein catheterization and the steps taken to treat the patient following its recognition. A discussion of technique for central venous catheterization, indications for suspicion of arterial puncture, methods for confirming venous or arterial placement, appropriate methods for management of carotid artery cannulation, and the benefit of ultrasound in central venous cannulation follow. Through the appropriate use of equipment, early detection and management of carotid artery injury, and proper training, patient outcomes may be improved.

    Background Central venous catheter-associated bloodstream infections in children are an increasingly recognized serious safety problem worldwide, but are often preventable. Central venous catheter bundles have proved effective to prevent such infections. Successful implementation requires changes in the hospital system as well as in healthcare professionals’ behaviour. The aim of the study is to evaluate process and outcome of implementation of a state-of-the-art central venous catheter insertion and maintenance bundle in a large university children’s hospital. Methods/design An interrupted time series design will be used; the study will encompass all children who need a central venous catheter. New state-of-the-art central venous catheter bundles will be developed. The Pronovost-model will guide the implementation process. We developed a tailored multifaceted implementation strategy consisting of reminders, feedback, management support, local opinion leaders, and education. Primary outcome measure is the number of catheter-associated infections per 1000 line-days. The process outcome is degree of adherence to use of these central venous catheter bundles is the secondary outcome. A cost-effectiveness analysis is part of the study. Outcomes will be monitored during three periods: baseline, pre-intervention, and post-intervention for over 48 months. Discussion This model-based implementation strategy will reveal the challenges of implementing a hospital-wide safety program. This work will add to the body of knowledge in the field of implementation. We postulate that healthcare workers’ willingness to shift from providing habitual care to state-of-the-art care may reflect the need for consistent care improvement.

    Maintenance of central venous access in patients with chronic medical conditions such as short bowel syndrome demands forethought and ingenuity. We describe an innovative technique for re-utilizing central venous access sites in patients who have chronic central venous access needs. Records of patients undergoing this technique were reviewed between August 2012 and December 2015. The technique involves "cutting-down" to the sterile fibrous tunnel that naturally forms around tunneled catheters. The fibrous sheath is then isolated and controlled much as would be done for a venous "cut-down." A separate exit site is then created for the new catheter and it is tunneled to the "cut-down" site per routine. The non-functioning catheter is then removed from the surgical field. The proximal fibrous sheath is finally cannulated either directly with the new catheter or with a wire/dilator system. This technique effectively re-uses the same venous access point while allowing for a complete change of the physical line and external site. Twenty attempts at this technique were made in twelve patients; six patients underwent the site re-utilization procedure multiple times. Re-using the fibrous tunnel to re-cycle the internal catheter site was successful in seventeen of twenty attempts. All patients had chronic conditions leading to difficult long-term central venous access [short bowel syndrome (6), hemophilia (2), cystic fibrosis (1), chronic need for central IV access (3)]. Indications for catheter replacement included catheter occlusion/mechanical failure/breakage (9), dislodgement (6), infection (1), and inadequate catheter length due to patient growth (4). Broviac/Hickman catheter sites were most commonly re-used (13; one failure); re-using a portcath site was successful in 5 of 7 attempts. There were no short term infections or mechanical complications. We describe a novel technique for salvaging tunneled central venous catheter access sites. This technique is well suited

    Background Long-term central venous catheters are essential for the management of chronic medical conditions, including childhood cancer. Catheter occlusion is associated with an increased risk of subsequent complications, including bloodstream infection, venous thrombosis, and catheter fracture. Therefore, predicting and pre-emptively treating occlusions should prevent complications, but no method for predicting such occlusions has been developed. Methods We conducted a prospective trial to determine the feasibility, acceptability, and efficacy of catheter-resistance monitoring, a novel approach to predicting central venous catheter occlusion in pediatric patients. Participants who had tunneled catheters and were receiving treatment for cancer or undergoing hematopoietic stem cell transplantation underwent weekly catheter-resistance monitoring for up to 12 weeks. Resistance was assessed by measuring the inline pressure at multiple flow-rates via a syringe pump system fitted with a pressure-sensing transducer. When turbulent flow through the device was evident, resistance was not estimated, and the result was noted as “non-laminar.” Results Ten patients attended 113 catheter-resistance monitoring visits. Elevated catheter resistance (>8.8% increase) was strongly associated with the subsequent development of acute catheter occlusion within 10 days (odds ratio = 6.2; 95% confidence interval, 1.8–21.5; p <0.01; sensitivity, 75%; specificity, 67%). A combined prediction model comprising either change in resistance greater than 8.8% or a non-laminar result predicted subsequent occlusion (odds ratio = 6.8; 95% confidence interval, 2.0–22.8; p = 0.002; sensitivity, 80%; specificity, 63%). Participants rated catheter-resistance monitoring as highly acceptable. Conclusions In this pediatric hematology and oncology population, catheter-resistance monitoring is feasible, acceptable, and predicts imminent catheter occlusion. Larger studies are required to validate

    Central venous catheters are a popular choice for the initiation of hemodialysis or for bridging between different types of access. Despite this, they have many drawbacks including a high morbidity from thrombosis and infection. Advances in technology have allowed placement of these lines relatively safely, and national guidelines have been established to help prevent complications. There is an established algorithm for location and technique for placement that minimizes harm to the patient; however, there are significant short- and long-term complications that proceduralists who place catheters should be able to recognize and manage. This review covers insertion and complications of central venous catheters for hemodialysis, and the social and economic impact of the use of catheters for initiating dialysis is reviewed.

    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. CRIs were high among catheters that were kept in situ for more than 3 days and emergency procedures where two or more attempts were required for catheterization (P < 0.05). In multivariate analysis of covariance duration of catheter in situ for >3 days, inexperienced venupucturist, more number of attempts and emergency CVC were associated with more incidence of CVCBSIs, with P <0.02. The duration of catheter in situ was negatively correlated (-0.53) and number of attempts required to put CVC was positively correlated (+0.39) with incidence of CVCBSIs. Sixty-five percent of the isolates belonged to the CONS group (13/20). Staphylococcus epidermidis showed

    Fourteen severely ill ventilated patients in an intensive care unit, requiring short-term total parenteral nutrition, were examined for catheter-related infection. Microbiological analysis using Maki's SQ technique was carried out on catheter exit site, catheter hub, proximal subcutaneous segment of catheter and catheter up. Qualitative cultures were carried out on total parenteral nutrition and peripheral blood samples. Twenty six of 29 catheters removed (90%) were culture positive but only 7 catheters were related to positive blood cultures, giving a catheter-related bacteremia (CRB) rate of 24%. Haematogenous seeding was strongly implicated in 7/29 (24%) of catheters. Patients' skin flora appeared to be the main source of catheter-related infection. The organisms isolated for patients with CRB included coagulase-negative staphylococci, Acinetobacter and Klebsiella. It is suggested that to control infective complications of central venous catheters, emphasis should be focused on specialised intravenous therapy teams and the use of strict protocols for insertion and care of central lines.

    Vascular access in paediatric patients with chronic and/or life-threatening illness is crucial to survival. Access is frequently lost in this group because of thrombosis, infection, or displacement, and vascular options can quickly be exhausted. The last resort access procedure is generally a direct atrial catheter inserted via a thoracotomy. A viable alternative is the percutaneous transhepatic Broviac catheter (Bard Access Systems, Salt Lake City, UT). We retrospectively reviewed the charts of 5 patients who underwent percutaneous transhepatic Broviac insertion for long-term access over a 4-year period in a single institution. Four of the patients (80%) had a significant cardiac abnormality, with 1 patient requiring long-term parenteral nutrition after complicated necrotizing enterocolitis. All patients had significant caval thrombosis, which precluded them having placement of a standard percutaneous or openly placed central catheter. Of the 5 patients, 2 (40%) died of cardiac-related illnesses. Of the 3 surviving patients, 2 had functioning catheters electively removed because they were no longer required. One catheter was removed at thoracotomy for right atrial perforation because of catheter erosion. Vascular access in paediatric patients with chronic and/or life-threatening illness is crucial to survival. Transhepatic central venous catheters are a feasible, reliable, and relatively easily placed form of central access in patients with multiple venous thromboses requiring long-term access. This route should be considered in paediatric patients requiring central access in preference to a thoracotomy.

    Long-term central venous catheters (CVC) facilitate care for patients with chronic illnesses, but catheter occlusions and catheter-related thrombosis (CRT) are common complications. This review summarizes management of CVC and CRT. Mechanical CVC occlusions require cause-specific therapy; whereas, thrombotic occlusions usually resolve with thrombolytic therapy, such as alteplase. Prophylaxis with thrombolytic flushes may decrease CVC infections and CRT, but confirmatory studies and cost-effectiveness analysis are needed. Risk factors for CRT include previous catheter infections, malposition of the catheter tip, and prothrombotic states. CRT can lead to catheter infection, pulmonary embolism, and post-thrombotic syndrome. CRT is diagnosed primarily using Doppler ultrasound or venography and treated with anticoagulation for 6 weeks to a year, depending on the extent of the thrombus, response to initial therapy, and whether thrombophilic factors persist. Prevention of CRT includes proper positioning of the CVC and prevention of infections; anticoagulation prophylaxis is not recommended at present. PMID:19595350

Results: The mean age of nurses was 33.60 ± 7.34 years and mean duration for oncology nursing experience was 2.65 ± 0.91 years. Nurses had correct information about the importance of selecting peripheral venous catheter and choosing the placement area for chemotherapy administration (63.6%), control of catheter before the administration (93.9%), influence of chemotherapeutic agent on length of catheter (40.6%), and management of extravasation (75.7%). Nurses also had correct information about the first use of port catheter (67.3%) and checking the catheter whether it is working properly or not (75.8%). Conclusions: In General, nurses’ level of knowledge related to catheter is 50% and higher. It is recommended to increase the knowledge of nurses about evidence-based information for catheter care as a step to safe chemotherapy practice. PMID:28217732

    Purpose. To compare the differences in practice and outcome of all radiologically and surgically placed central venous catheters retrospectively over a 2-year period simultaneously, at a single institution. Methods.A total of 253 Hickman catheters were inserted in 209 patients; 120 were placed radiologically in 102 patients and 133 were placed surgically in 107 patients. The indication was chemotherapy in 76% of radiological and in 47% of surgical cases; the remainder were for total parenteral nutrition and venous access. Results. There were 6 (4.5%) primary surgical failures and a further 17 (13%) surgical cases requiring multiple placement attempts. Pneumothorax occurred once (0.8%) surgically and four times (3.3%) radiologically. There were no radiological primary misplacements but there were five (3.7%) surgical ones. Catheter or central vein thrombosis occurred in four (3.3%) radiological and five (3.7%) surgical cases. The rate of infection per 1000 catheter-days was 1.9 in radiologically placed catheters and 4.0 in surgically placed ones (p<0.001). Average catheter life-span was similar for the two placement methods (100{+-}23 days). Conclusion. Radiological placement is consistently more reliable than surgical placement. There are fewer placement complications and fewer catheter infections overall.

    Central venous catheters (CVCs) nowadays constitute critical devices used in medical care, namely in intensive care units. However, CVCs also represent one of the indwelling medical devices with enhanced risk of nosocomial device-related infection. Catheter-related infections (CRIs) are a major cause of patient morbidity and mortality, often justifying premature catheter removal and an increase in costs and use of resources. Adhesion and subsequent biofilm formation on the surfaces of indwelling catheters is elemental to the onset of pathogenesis. Seeking the prevention of CVC colonisation and CRI, a variety of approaches have been studied, tested and, in some cases, already applied in clinical practice. This review looks at the current preventive strategies often used to decrease the risk of CRIs due to colonization and biofilm formation on catheter surfaces, as well as at the more recent approaches under investigation.

    The insertion of Hickman central venous catheters for chronic venous access is a procedure usually conducted in the operating theatre under local or general anaesthesia. In a prospective study over a one year period we have assessed the feasibility of radiologists inserting central venous catheters for long term access. A subclavicular approach to the subclavian vein with prior digital subtraction angiography or video imaging of the vein was the technique of choice. Thirty-one Hickman catheters were inserted in 21 patients. All but two patients had a haematological malignancy. Ages ranged from 19 to 77 years. The mean time for insertion was 43 min (range 20-80 min). The catheters remained in situ for between 2 days and 242 days with a mean of 86 days. There was one documented line infection; nine patients had episodes of septicaemia with identified organisms, and a further six had pyrexias of unknown origin during the line indwelling period. There were four documented line and or ipsilateral subclavian vein thromboses, and one death occurred within 36 hours of the procedure. We conclude that radiological placement is an excellent alternative to 'blind' surgical placement. Screening during insertion provides immediate facilities for correction of malposition and monitoring of immediate complications. The time taken for catheter insertion did not impede the usual patient throughout in the interventional radiology suite.

    When planning parenteral nutrition (PN), the proper choice, insertion, and nursing of the venous access are of paramount importance. In hospitalized patients, PN can be delivered through short-term, non-tunneled central venous catheters, through peripherally inserted central catheters (PICC), or - for limited period of time and with limitation in the osmolarity and composition of the solution - through peripheral venous access devices (short cannulas and midline catheters). Home PN usually requires PICCs or - if planned for an extended or unlimited time - long-term venous access devices (tunneled catheters and totally implantable ports). The most appropriate site for central venous access will take into account many factors, including the patient's conditions and the relative risk of infective and non-infective complications associated with each site. Ultrasound-guided venepuncture is strongly recommended for access to all central veins. For parenteral nutrition, the ideal position of the catheter tip is between the lower third of the superior cava vein and the upper third of the right atrium; this should preferably be checked during the procedure. Catheter-related bloodstream infection is an important and still too common complication of parenteral nutrition. The risk of infection can be reduced by adopting cost-effective, evidence-based interventions such as proper education and specific training of the staff, an adequate hand washing policy, proper choices of the type of device and the site of insertion, use of maximal barrier protection during insertion, use of chlorhexidine as antiseptic prior to insertion and for disinfecting the exit site thereafter, appropriate policies for the dressing of the exit site, routine changes of administration sets, and removal of central lines as soon as they are no longer necessary. Most non-infective complications of central venous access devices can also be prevented by appropriate, standardized protocols for line insertion

In multivariate analysis, we found a 7-fold higher risk of central line-associated bloodstream infection with central venous catheter insertion in the internal jugular vein as compared with the subclavian access. Patients with central line-associated bloodstream infection had a higher incidence of acute renal failure.

    Central venous catheters (CVC) play an essential role in the management of cancer patients. Venous thrombosis is a common complication of CVC. The incidence of CVC-associated venous thromboembolism (CVC-VTE) is 1.7 per 1000 catheter days. Risk factors for CVC-VTE include the patient's underlying cancer, a history of previous thrombotic events and the location and type of CVC. Anticoagulant prophylaxis is not effective for CVC-VTE. Anticoagulation alone is the preferred initial treatment for CVC-VTE. CVC removal may be considered in refractory cases or when anticoagulation is contraindicated. Thrombolytic therapy is reserved for patients with limb-threatening thrombosis or thrombosis unresponsive to conventional treatment. Anticoagulation should be continued for at least 3 months or as long as the CVC is present.

    Background A 72 year old male was admitted to the medical intensive care unit with septic shock. Case presentation A left subclavian central venous catheter was inserted on the day of admission whose tip was pushing against the wall of the vessel lumen. The patient's condition improved with treatment, but three days later had a new episode of acute hypotension. CT scan of the chest showed that the catheter had eroded through the superior vena cava wall. Conclusion The catheter was pulled out and patient recovered from the complication with supportive therapy. Care should be taken that the tip of the catheter is in the center of the vessel lumen to avoid this rare, but potentially life threatening, complication. PMID:19036145

    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.

    Abstract Objective: to evaluate the effectiveness and safety in the use of second-generation central venous catheters impregnated in clorhexidine and silver sulfadiazine when compared with other catheters, being them impregnated or not, in order to prevent the bloodstream infection prevention. Method: systematic review with meta-analysis. Databases searched: MEDLINE, EMBASE, CINAHL, LILACS/SciELO, Cochrane CENTRAL; search in Congress Proceedings and records from Clinical Trials. Results: 1.235 studies were identified, 97 were pre-selected and 4 were included. In catheter-related bloodstream infection, there was no statistical significance between second-generation impregnated catheter compared with the non-impregnated ones, absolute relative risk 1,5% confidence interval 95% (3%-1%), relative risk 0,68 (confidence interval 95%, 0,40-1,15) and number needed to treat 66. In the sensitivity analysis, there was less bloodstream infection in impregnated catheters (relative risk 0,50, confidence interval 95%, 0,26-0,96). Lower colonization, absolute relative risk 9,6% (confidence interval 95%, 10% to 4%), relative risk 0,51 (confidence interval 95% from 0,38-0,85) and number needed to treat 5. Conclusion: the use of second-generation catheters was effective in reducing the catheter colonization and infection when a sensitivity analysis is performed. Future clinical trials are suggested to evaluate sepsis rates, mortality and adverse effects. PMID:27508901

    Injuries to blood vessels near the heart can quickly become life-threatening and include arterial injuries during central venous puncture, which can lead to hemorrhagic shock. We report 6 patients in whom injury to the subclavian artery and vein led to life-threatening complications. Central venous catheters are associated with a multitude of risks, such as venous thrombosis, air embolism, systemic or local infections, paresthesia, hemothorax, pneumothorax, and cervical hematoma, which are not always immediately discernible. The subclavian catheter is at a somewhat lower risk of catheter-associated sepsis and symptomatic venous thrombosis than approaches via the internal jugular and femoral veins. Indeed, access via the subclavian vein carries a substantial risk of pneumo- and hemothorax. Damage to the subclavian vein or artery can also occur during deliberate and inadvertent punctures and result in life-threatening complications. Therefore, careful consideration of the access route is required in relation to the patient and the clinical situation, to keep the incidence of complications as low as possible. For catheterization of the subclavian vein, puncture of the axillary vein in the infraclavicular fossa is a good alternative, because ultrasound imaging of the target vessel is easier than in the subclavian vein and the puncture can be performed much further from the lung.

    There is an increasing incidence of infective endocarditis secondary to central venous catheters, which is termed as 'healthcare-associated infective endocarditis'. There is an increased risk of getting infective endocarditis in conditions with malnutrition and also if the tip of the central venous catheter is deep in the right atrium close to the tricuspid valve. We present a case of 31-year-old female who had all these risk factors. She was admitted to the hospital for the work up of the weight loss and was diagnosed with celiac disease. Central venous access was obtained because of poor peripheral intravenous access via the peripherally inserted central catheter which was complicated by thrombosis and removed after three days of insertion, and she was started on anticoagulation. Two weeks after being discharged, she presented to the emergency department with fever, shortness of breath, and had signs of congestive heart failure. A computed tomography of the chest for pulmonary embolism was taken and showed small clot burden pulmonary embolism and two cavitary lesions in the right lung. A transthoracic echocardiogram was taken and showed vegetation on the tricuspid valve and blood cultures were positive for Staphylococcus aureus. Hence, a diagnosis of infective endocarditis was made, and she was treated with intravenous antibiotics for a total of six weeks after a long and complicated hospital stay. PMID:28348945

Method: this is a descriptive, methodological study based on Paulo Freire's assumptions. The development of the script and video storyboard were based on scientific evidence, on the researchers' experience, and that of nurse experts, as well as on a virtual learning environment. Results: the items related to the script were approved by 97.2% of the nurses and the video was approved by 96.1%. Conclusion: the educational instrument was considered to be appropriate and we believe it will contribute to professional training in the nursing field, the updating of human resources, focusing on the educational process, including distance education. We believe it will consequently improve the quality of care provided to patients with central venous catheters. PMID:26626011

    A transfemoral venous approach is the current standard for accessing malpositioned and fractured central venous catheters (CVCs). The purpose of this study was (1) to describe a transbrachial approach for correction and (2) to assess the success and failure of this method in a pediatric population. A 12-year retrospective review of all patients referred for correction of malpositioned, retained, and fractured CVCs was conducted. Based on the performing interventionalist's preference, transbrachial or transfemoral venous sheaths where placed under ultrasonographic guidance. Diagnostic angiographic catheters and snares were used to manipulate the catheters. Patients who underwent the transfemoral approach received postprocedural monitoring for 4 hours, whereas patients who underwent the transbrachial approach were allowed unrestricted activity immediately after hemostasis was obtained. Technical success of malpositioned lines was defined (1) by final position in the superior vena cava or at the cavoatrial junction on postprocedural imaging or (2) by successful removal of retained catheter fragments, if present. Transbrachial approach was used for access in 11 patients. Problematic lines included malpositioned (n = 10) and retained (n = 1) lines. The ipsilateral arm was used for transbrachial entry in 7 patients. Initial use of angiographic catheters was attempted in 7 cases, of which 4 were successful. All 3 unsuccessful cases had tips positioned in the contralateral brachiocephalic vein, and these were successfully repositioned using snares. A combination of snares and angiographic catheters was used in 2 cases. Snares were used for all other cases. Technical success by way of the transbrachial approach was observed in all cases. Periprocedural follow-up demonstrated no immediate complications. We conclude that the transbrachial approach is a suitable alternative to the transfemoral approach for catheter tip position correction. Tip malposition in the contralateral

    Long-term intravenous catheters (LTIVC) are standard practice for patients with chronic diseases such as cancer, digestive disease requiring total parenteral nutrition or end-stage renal disease. Even if they greatly improved patients' care, the use of LTIVC is also associated with microbial contamination and subsequent infection. These catheter-related infections are associated with morbidity, mortality and increased health-care costs. As patients carrying these LTIVC stay at home for their treatment (home parenteral nutrition for instance) or between cycles of treatment (antineoplastic chemotherapy or dialysis), it is mandatory that general practitioner and nurses are aware of recent data on the epidemiology, diagnosis and treatment of LTIVC-related infections.

    BACKGROUND: The current standard for confirmation of correct supra-diaphragmatic central venous catheter (CVC) placement is with plain film chest radiography (CXR). We hypothesized that a simple point-of-care ultrasound (POCUS) protocol could effectively confirm placement and reduce time to confirmation. METHODS: We prospectively enrolled a convenience sample of patients in the emergency department and intensive care unit who required CVC placement. Correct positioning was considered if turbulent flow was visualized in the right atrium on sub-xiphoid, parasternal or apical cardiac ultrasound after injecting 5 cc of sterile, non-agitated, normal saline through the CVC. RESULTS: Seventy-eight patients were enrolled. POCUS had a sensitivity of 86.8% (95%CI 77.1%–93.5%) and specificity of 100% (95%CI 15.8%–100.0%) for identifying correct central venous catheter placement. Median POCUS and CXR completion were 16 minutes (IQR 10–29) and 32 minutes (IQR 19–45), respectively. CONCLUSION: Ultrasound may be an effective tool to confirm central venous catheter placement in instances where there is a delay in obtaining a confirmatory CXR. PMID:28123616

    The aim of this study was to evaluate the technical aspects and efficacy of placing tunneled central venous access catheters (CVA) in the inferior vena cava (IVC) via a direct translumbar approach. Between August 1994 and July 1998, 50 CVA (Hickman 13.5 F) were placed in the IVC via a direct translumbar approach in 46 patients (10 males, 36 females) with a mean age of 39.9 years (age range 10-87 years). The indications were chemotherapy administration plus leukoaphoresis (n = 39), bone marrow transplantation (n = 2) and hemodialysis (n = 5). The reasons for placing the CVA in the IVC were cosmetic (n = 34), supradiaphragmatic venous thrombosis (n = 8), previous catheter infection (n = 2), and non-functioning arteriovenous fistula (n = 2). There were no immediate complications. The mean period of time the CVA was in place was 3 months (15 days to 15 months), during which the function was excellent. The commonest late complication was infection (4 local, 6 bacteremia). Others included: pain (n = 2), ureteric fistula (n = 1), pericatheter fibrin sheath formation (n = 6) and catheter-tip impaction (n = 2). Two catheters were damaged due to postprocedural inappropriate manipulations and two others fell off due to incorrect fixation. Due to these complications, it was necessary to remove ten catheters, replace an additional four and reposition two. Direct translumbar catheterization of the IVC is a safe and effective way of placing a long-term CVA with a moderate complication rate.

    Recent advances in anticancer chemotherapy have resulted in an increase in the number of patients requiring a central venous port catheter, and the incidence of catheter pinch-off syndrome has been increasing. Catheter pinch-off syndrome is a rare and unusual complication. It is difficult to retrieve dislodged catheters from the pulmonary artery, especially if the catheter is stuck to the peripheral pulmonary artery. We herein describe the successful removal of a catheter stuck in the pulmonary artery with a stepwise approach. First, a pigtail catheter was used to tug the dislodged catheter in order to free the unilateral end. Then, a gooseneck snare was used to catch and pull the catheter out of the patient. The key to success is to free the end of the catheter. PMID:27668096

    Central venous catheterization (CVC)-related venous thrombosis is a common but serious clinical complication, thus prevention and treatment on this problem should be extensively investigated. In this research, we aimed to investigate the incidence rate of CVC-related venous thrombosis in senile patients and give a further discussion on the related risk factors and predictors. A total of 324 hospitalized senile male patients subjected to CVC were selected. Retrospective investigation and analysis were conducted on age, underlying diseases, clinical medications, catheterization position and side, catheter retention time, and incidence of CVC-related venous thrombosis complications. Basic laboratory test results during catheterization and thrombogenesis were also collected and analyzed. Among the 324 patients, 20 cases (6.17%) of CVC-related venous thrombosis were diagnoseds. The incidence rate of CVC-related venous thrombosis in subclavian vein catheterization was significantly lower than that in femoral vein catheterization (P<0.01) and that in internal jugular vein catheterization (P<0.05). No statistically significant difference was found between femoral vein catheterization and internal jugular vein catheterization (P<0.05). Previous venous thrombosis history (P<0.01), high lactate dehydrogenase level (P<0.01), low high-density lipoprotein (HDL) level (P<0.05), and low albumin level (P<0.05) were found as risk factors or predictors of CVC-related venous thrombosis in senile male patients. Subclavian vein catheterization was the most appropriate choice among senile patients to decrease the incidence of CVC-related venous thrombosis. Previous venous thrombosis history, high lactate dehydrogenase level, low HDL level, and low albumin level were important risk factors in predicting CVC-related venous thrombosis.

    Malfunctioning tunneled hemodialysis central venous catheters (CVCs), because of thrombotic or infectious complications, are frequently exchanged. During the CVC exchanging procedure, there are several possible technical complications, as in first insertion, including air embolism. Prevention remains the key to the management of air embolism. Herein, we emphasize the technical tricks capable of reducing the risk of air embolism in long-term CVC exchange. In particular, adoption of a 5 to 10 degrees Trendelenburg position, direct puncture of the previous CVC venous lumen for guide-wire insertion, as opposed to guide-wire introduction after cutting the CVC, a light manual compression of the internal jugular vein venotomy site after catheter removal. The Valsalva maneuvre in collaborating patients, valved introducers, and correction of hypovolemia are also useful precautions. Principles of air embolism diagnosis and treatment are also outlined in the article.

    Sixty central venous catheterizations in 53 patients were prospectively studied with respect to phlebographic findings after prolonged parenteral nutrition. Phlebography was performed by a special technique on completion of the intravenous therapy. Under fluoroscopic control, the central venous catheter was slowly removed, while simultaneously contrast medium was continuously injected through it. Two types of thrombosis were demonstrated--sleeve thrombosis, on 25 occasions (42%), and mural veno-occlusive thrombosis, on five occasions (8%). On removal of the catheter the sleeve thrombosis peeled off the catheter and in several cases it was noticed that parts of the sleeve thrombus or the entire sleeve became detached and were carried away with the blood flow. Although the sleeve thrombus seldom gave rise to any symptoms, this type of thrombosis is of great importance in view of the risk of pulmonary embolism, especially in connection with removal of the catheter. With use of the described phlebographic technique thrombi of this type can be visualized. Images Fig. 1A. Fig. 1B. Fig. 2. Fig. 3. Fig. 4. PMID:7305496

    Peripherally-inserted central catheters (PICC) have a greater retention time and less complications compared to central venous catheters (CVC). The study was conducted from From January of 2014 to December 2015 at Beijing DiTan Hospital, Beijing, China, and comprised 70 patients undergoing devascularisation. Of the total, 36(51.4%) patients underwent placement of PICC (Group A), while 34(48.6%) underwent had CVC (Group B). Venous catheterisation was successful in all patients. The median duration of venous catheterization in Group A was greater than that in Group B (p=0.002). Catheter-associated complications did not differ between the groups (p=0.46). The level of blood platelet (PLT) count, Prothrombin activity (PTA) and white blood cell (WBC) count before venous catheterisation were independent risk factors for bleeding at the puncture site and catheter-related infections. A Power PICC may be a better choice than a CVC in patients undergoing devascularisation requiring catheterisation. For patients with a lower PLT count, a decreased PTA, or a decreased WBC, venous catheterisation should be performed with caution.

    Background and Aim The use of venous catheters is a widespread practice, especially in oncological and oncohematological units. The objective of this study was to evaluate the complications associated with peripherally inserted central catheters (PICCs) in a cohort of patients. Materials and Methods In this retrospective cohort study, we included all patient carrying PICCs (n = 603) inserted at our institute between October 2010 and December 2013. The main variables collected were medical diagnosis, catheter care, location, duration of catheterization, reasons for catheter removal, complications, and nursing care. Complications were classified as infection, thrombosis, phlebitis, migration, edema, and/or ecchymosis. Results All patients were treated according to the same “nursing care” protocol. The incidence rate of complications was two cases per 1000 days of catheter duration. The most relevant complications were infection and thrombosis, both with an incidence of 0.17 cases per 1000 days of the total catheterization period. The total average duration of catheterization was 170 days [SD 6.06]. Additionally to “end of treatment” (48.42%) and “exitus”, (22.53%) the most frequent cause of removal was migration (displacement towards the exterior) of the catheter (5.80%). Conclusions PICCs are safe devices that allow the administration of long-term treatment and preserve the integrity of the venous system of the patient. Proper care of the catheter is very important to improve the quality life of patients with oncologic and hematologic conditions. Therefore, correct training of professionals and patients as well as following the latest scientific recommendations are particularly relevant. PMID:27588946

    The use ofa central venous(CV)port system has become common for the treatment of patients with tumors. We report on the failure to remove CV catheters in 2 patients. The first patient was a 50 years woman with acute myeloid leukemia. She underwent CV port implantation via the left brachial approach 11 years previously. The second patient was an 80 years man with a lower gingival carcinoma. He underwent CV port implantation via the left brachial approach 6 years previously. CV catheter removal was attempted in both patients, but was unsuccessful because of strong adhesion to the vessel wall. Based on our experience, if catheter removal is impossible, its retention is more suitable.

    Kocuria kristinae is a catalase-positive, coagulase-negative, Gram-positive coccus found in the environment and in normal skin and mucosa in humans; however, it is rarely isolated from clinical specimens and is considered a nonpathogenic bacterium. We describe a case of catheter-related bacteremia due to K. kristinae in a young adult with propionic acidemia undergoing periodic hemodialysis. The patient had a central venous catheter implanted for total parenteral nutrition approximately 6 months prior to the onset of symptoms because of repeated acute pancreatitis. K. kristinae was isolated from two sets of blood cultures collected from the catheter. Vancomycin followed by cefazolin for 16 days and 5-day ethanol lock therapy successfully eradicated the K. kristinae bacteremia. Although human infections with this organism appear to be rare and are sometimes considered to result from contamination, physicians should not underestimate its significance when it is isolated in clinical specimens.

    ABSTRACT Introduction: Central Venous Catheters (CVC) are essential in everyday medical practice, especially in treating patients in intensive care units (ICU). The application of these catheters is accompanied with the risk of complications, such as the complications caused during the CVC insertion, infections at the location of the insertion, and complications during the use of the catheter, sepsis and other metastatic infections. Patients and methods: This study is a retrospective-prospective and it was implemented in the period 1st January 2011- 31st December 2012. It included 108 examinees with CVC placed for more than 7 days. Results: The most common complications occurring in more than 2 attempts of CVC applications are: hearth arrhythmias in both groups in 12 cases, 7 in multi-lumen (12.72%) and 5 in mono-lumen ones (9.43%). Artery puncture occurs in both groups in 7 cases, 5 in multi-lumen (9.09%) and 2 in mono-lumen ones (3.77%). Hematoma occurred in both groups in 4 cases, 3 in multi-lumen CVCs (5.45%) and 1 in mono-lumen ones (1.88%). The most common complication in multi-lumen catheters was heart arrhythmia, in 20 cases (36.37%). The most common complications in mono-lumen CVCs was hearth arrhythmias, in 20 cases as extrasystoles and they were registered in 16 catheter insertions (30.18%). Out of total number of catheters of both groups, out of 108 catheters the complications during insertion occurred in 49 catheters (45.40%). The most common complications in both groups were heart arrhythmias, artery punctures and hematomas at the place of catheter insertion. PMID:25568558

    Central venous catheter (CVC) placement is associated with increased risk of thrombosis in the paediatric population, particularly in relation to the type of catheter and the manner of its insertion. Here, we investigate risk factors associated with CVC-related thrombosis in children, with particular emphasis on positioning of the catheter tip. Patients aged 0-18 who underwent at least one CVC placement from 2008 to 2013 at a single centre with a subsequent follow-up echocardiogram were included for a total of 104 patients and 147 lines. Data on clinical and catheter-related risk factors were collected from patient charts. Statistical analysis using Pearson's χ tests, independent samples t-test, and odds ratios were used to assess potential risk factors for thrombosis. Neither insertion site (subclavian vein or otherwise), left- vs. right-sided insertion, nor catheter type were significant risk factors for thrombosis. There were no thrombotic events reported at the superior vena cava (SVC)-right atrium junction and no significant differences in thrombotic risk with initial tip placement in the SVC-right atrium junction vs. the SVC, right atrium, or inferior vena cava. Acute lymphoblastic leukaemia was a major clinical risk factor for thrombosis. Tip movement was common and may have been an important factor in the development of CVC-related thrombi. Prospective studies can yield insight into the role of follow-up imaging in the prevention of catheter-related thrombosis in children.

    An adequate vascular access is of importance for the treatment of patients with cancer and complex illnesses in the intensive, perioperative or palliative care setting. Deep vein thrombosis and thrombotic occlusion are the most common complications attributed to central venous catheters in short-term and, especially, in long-term use. In this review we will focus on the risk factors, management and prevention strategies of catheter-related thrombosis and occlusion. Due to the lack of randomised controlled trials, there is still controversy about the optimal treatment of catheter-related thrombotic complications, and therapy has been widely adopted using the evidence concerning lower extremity deep vein thrombosis. Given the increasing use of central venous catheters in patients that require long-term intravenous therapy, the problem of upper extremity deep venous thrombosis can be expected to increase in the future. We provide data for establishing a more uniform strategy for preventing, diagnosing and treating catheter-related thrombotic complications.

    For successful catheter placement, central venous cannulation (CVC) through internal jugular vein and subclavian vein has been recommended in both adult and pediatric patients. But it carries a risk of serious complications, such as pneumothorax, carotid, or subclavian artery puncture, which can be life-threatening, particularly in critically ill children. So a prospective study was carried out to determine the success rate of correct catheter tip placement during CVC through antecubital veins in pediatric neurosurgical patients. A total of 200 pediatric patients (age 1-15 years) of either sex were studied. Basilic or cephalic veins of either arm were selected. All the patients were cannulated in the operation room under general anesthesia. Single lumen, proper size catheters (with stillete) were used for cannulation. The catheter was inserted in supine position with the arm abducted at right angle to the body and neck turned ipsilaterally. The length of insertion was determined from cubital fossa to the right second intercostal space. The exact position of the tip of the catheter was confirmed radiologically in ICU. Correct catheter tip placement was achieved in 98 (49%) patients. Multivariate logistic regression analysis of data shows that there was no statistically significant difference among correct and incorrect catheter tip placement in relation to factors including sex, side of cannulation (left or right), and type of vein (basilic or cephalic). The analysis of correct catheter tip placement in relation to age showed that the highest success rate was achieved in children of age group 6 to 10 years (60.2%) followed by 30.6% in the 11 to 15 year group. The lowest success rate of tip placement of only 9.2% was observed in younger children of age 1 to 5 years, which is statistically significant (P = 0.001). Of 102 incorrect placements reported, 37% were in 1 to 5 year age group versus 9.2% correct tip placements. The most common unsatisfactory placements were

    Indwelling central venous catheters (CVCs) are used in the management of hematologic patients. However, insertion and maintenance of CVCs are susceptible to complications. Study design and methods data concerning 388 consecutive catheterisations, performed in oncohematologic patients between April 2003 and December 2004, were prospectively collected. At insertion thrombocytopenia was present in 109 cases (28.1%) and neutropenia in 67 (17.3%). Hemorrhage after CVC insertion occurred in five thrombocytopenic patients (1.3%). The median duration of catheterisation was 18.8 days (range 1-89), longer in the 7-French CVCs utilised in leukemic patients (24.3 days) and shorter in 12-French CVCs (11 days), used for PBSC harvesting. Deep venous thrombosis was diagnosed in 13 cases (3.3%). Ninety-two catheterisations (12.6/1000 days-catheter) were complicated by infections: 19 local infections (4.8%) and 73 (18.8%) bacteraemias of which 45 (11.6%) were catheter-related, mainly due to Gram positive germs (32/45, 71.1%). The frequency of catheter-related bacteraemia was 7.2 events/1000 days-catheter. Thirteen CVCs were removed due to thrombosis, 15 due to infections, 20 due to malfunction, the remaining 333 at patients discharge. At univariate analysis high-dose chemotherapy (p = 0.013), 7-Fr lumen (p = 0.023), acute myeloid leukemia (AML) (p = 0.001), duration of neutropenia >10 days and length of catheterisation were significantly correlated to infection. Multivariate analysis confirmed the duration of catheterisation, AML and high-dose chemotherapy as risk factors. Even though hematological in-patients are at increased risk for bleeding and infections, non-tunnelled CVCs offer a safe venous access also in patients affected by severe thrombocytopenia and prolonged neutropenia.

    Objective Although use of the peripherally inserted central venous catheter (PICC) has become increasingly common, there are few reports of PICCs used for patients with hematologic diseases. In this study, we analyzed the safety of PICC placement in patients with hematologic diseases where PICCs had been placed to perform blood collection, blood transfusion, drug administration, and hematopoietic stem cell transplantation. Methods This study included 142 PICCs placed in 95 patients managed at our department from November 2013 to December 2015. The PICCs used were the GroshongⓇ Catheter (NXT single-lumen; BARD Inc.). Results A total of 95 patients underwent the placement of 142 PICCs. The mean patient age was 65.5 years. The total duration of catheterization was 8,089 days, with a mean duration of 57.0 days. Chemotherapy was administered through 107 catheters. Stem cells were injected through 12 catheters. Although a fever was observed in association with 103 catheters, it was generally controlled by antimicrobial therapy. There were 18 catheter-related bloodstream infection (CRBSI) cases, an incidence equivalent to 2.1 cases per 1,000 catheter-days. Conclusion The present study demonstrated a low CRBSI incidence rate and found no evidence of serious complications with PICC placement. PICCs can be used for blood collection, blood transfusion, drug administration, and hematopoietic stem cell transplantation without problems. Thus, PICC placement appears to be a safe procedure for patients with hematologic diseases. Safe catheters are therefore urgently needed for these patients. We expect that PICCs will be widely adopted in Japan in the near future. PMID:28202859

    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.

    Introducción: los catéteres venosos centrales (CVC) son de gran utilidad en la práctica médica actual; sin embargo, no están exentos de riesgos, lo que incrementa la morbilidad y mortalidad, especialmente en los recién nacidos (RN). El objetivo fue registrar la frecuencia de complicaciones de los CVC y su duración en RN en una unidad de cuidados intensivos neonatales (UCIN) de tercer nivel. Métodos: se realizó un estudio observacional descriptivo, prolectivo en la UCIN del Hospital de Pediatría del Centro Médico Nacional Siglo XXI. Se registraron variables demográficas, perinatales y del CVC. Resultados: se incluyeron 123 RN a quienes se les colocaron 152 CVC. La técnica más usada para la inserción del CVC fue la punción (percutánea o subclavia) en 56.6 % (n = 86). En 48.7 % (n = 74) de los CVC se presentó alguna complicación. Las más frecuentes fueron colonización en 32.4 % (n = 24) y bacteriemia relacionada con CVC en 27 % (n = 20). La probabilidad de duración de los CVC libres de complicaciones fue de 93.4 % a los 10 días y de 91.4 % a los 17 días. Los catéteres venosos no centrales tuvieron menor probabilidad de duración. Conclusión: la mayoría de las complicaciones de los CVC se presentaron en las primeras dos semanas de haber sido instalados. Las complicaciones infecciosas fueron las más frecuentes.

    Vascular access is invaluable in the treatment of hospitalized patients. Central venous catheters provide a durable and long-term solution while saving patients from repeated needle sticks for peripheral IVs and blood draws. The initial catheter placement procedure and long-term catheter usage place patients at risk for infection. The goal of this project was to develop a system to track and evaluate central line-associated blood stream infections related to interventional radiology placement of central venous catheters. A customized web-based clinical database was developed via open-source tools to provide a dashboard for data mining and analysis of the catheter placement and infection information. Preliminary results were gathered over a 4-month period confirming the utility of the system. The tools and methodology employed to develop the vascular access tracking system could be easily tailored to other clinical scenarios to assist in quality control and improvement programs.

    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.

    We report the case of a femoral vein cannulation in a critically ill trauma patient with the malposition of a large-bore central venous catheter in the urinary bladder. Recognition of the malposition was hampered by bloody tamponade of the bladder in the context of blunt thoraco-abdominal trauma with kidney and liver laceration. A high index of clinical suspicion and the institution of adequate therapy were the key to achieving a successful clinical outcome. We discuss the anatomy of femoral veins, including their close relation to a distended bladder. The application of ultrasound even in emergency situations is stressed.

    We report a case of a preterm neonate born at 26 weeks' of gestation diagnosed with unilateral diaphragmatic paralysis. This paralysis was a consequence of a phrenic nerve injury due to extravasation of hyperosmolar parenteral nutrition fluid in the upper thorax. Chest X-rays and ultrasonography confirmed the diagnosis. The neonate was treated with prolonged respiratory support and did not require surgical treatment. This report describes a case of hemidiaphragmatic paralysis as a complication of central venous catheter insertion. In neonates, spontaneous recovery of diaphragmatic paralysis is possible. This study concludes that recovery of extravasation injury-induced phrenic nerve palsy in the context of conservative management is possible.

    Peripherally inserted central venous catheters (PICCs) are of growing interest because they allow intravenous therapies up to several months. The appropriate management of the PICCs is crucial to minimize complications and largely depends on the right information for everyone who cares for the patient. To reach this goal we develop the mobile application "PICC App" to provide the necessary information for all involved persons in the outpatient setting. We expect to be able to report about the PICC App and the results of the usability evaluation with pilot users.

The subclavian site was associated with a lower rate of short-term complications, including catheter-related bloodstream infection and deep venous thrombosis, compared to the femoral or internal jugular site. Nephrologists should be aware of this study and should continue to advocate for alternatives to subclavian vein catheter placement in patients with chronic kidney disease who are expected to require arteriovenous access for dialysis in the future.

    Three-dimensional (3D) echocardiography is becoming widely available and with novel applications. We report an interesting case of a 68-year-old lady with a central venous thrombosis coincident with both a dialysis catheter infection and a recent pacemaker insertion. Two-dimensional transesophageal echocardiography was unable to delineate whether the thrombosis was involved with the pacemaker wire or due to the tunneled catheter infection. The use of 3D echocardiography was able to produce distinct images aiding diagnosis. This circumvented the need for invasive investigations and inappropriate, high-risk removal of the pacing wire. This case highlights the emerging application of 3D echocardiography in routine nephrology practice. PMID:26688761

    An ultrasound investigation was undertaken of the neck region of 42 patients with normal neck anatomy in order to determine whether the results of ultrasound-gained topographical data provided pointers to the choice of entry site to the internal jugular vein (IJV). In addition, the IJV was punctured under ultrasound control in 23 patients in an intensive care unit in whom there was a problem of increased bleeding tendency, anatomical difficulty or previously failed "blind" puncture. In all of them a central venous catheter was placed without complication by the Seldinger technique via the primary chosen point for puncture. An approach through the sternocleidomastoid muscle, between the cricoid level and the "central" place of puncture between the two bellies of the sternocleidomastoid muscle proved to be the most satisfactory compromise between easy application of the ultrasound head, large vein diameter and reduction of any risk of mistakenly puncturing artery or pleura. This approach has to be varied according to the ultrasound findings. It is concluded from this experience that ultrasound is suitable for the placement of central venous catheters. But since the equipment is bulky it cannot be used in an emergency.

    Catheter-related bloodstream infections (CRBSI) are a significant cause of morbidity and excess hospital cost. Data from prospective, randomized trials demonstrate that the risk of these infections can be minimized by simple interventions. Changing the behaviour of healthcare workers who insert and care for intravascular catheters is imperative. Creating a culture of patient safety and assuring easy access to the products necessary to maintain strict asepsis during catheter insertion, dressing changes, and when manipulating catheter hubs, will enhance adherence to optimal practice and will reduce the risk posed to the millions of patients in need of such devices.

    The use of peripherally inserted central catheter (PICC) line for central venous access in thermally injured patients has increased in recent years despite a lack of evidence regarding safety in this patient population. A recent survey of invasive catheter practices among 44 burn centers in the United States found that 37% of burn units use PICC lines as part of their treatment protocol. The goal of this study was to compare PICC-associated complication rates with the existing literature in both the critical care and burn settings. The methodology involved is a single institution retrospective cohort review of patients who received a PICC line during admission to a regional burn unit between 2008 and 2013. Fifty-three patients were identified with a total of seventy-three PICC lines. The primary outcome measurement for this study was indication for PICC line discontinuation. The most common reason for PICC line discontinuation was that the line was no longer indicated (45.2%). Four cases of symptomatic upper extremity deep vein thrombosis (5.5%) and three cases of central line-associated bloodstream infection (4.3%, 2.72 infections per 1000 line days) were identified. PICC lines were in situ an average of 15 days (range 1 to 49 days). We suggest that PICC line-associated complication rates are similar to those published in the critical care literature. Though these rates are higher than those published in the burn literature, they are similar to central venous catheter-associated complication rates. While PICC lines can be a useful resource in the treatment of the thermally injured patient, they are associated with significant and potentially fatal risks.

    Central venous catheter infections are the leading cause of healthcare-associated bloodstream infections and contribute significantly to mortality and morbidity in neonatal intensive care units. Moreover, infection poses significant economic consequence which increased hospital costs and increased length of hospital stay. Prevention strategies are detailed in guidelines published by the Centers for Disease Control and Prevention (CDC) in the United States; nevertheless, recent surveys in neonatal units in the United States, and Australia and New Zealand demonstrate these are not always followed. This review discusses the numerous evidence-based strategies to prevent catheter infections including hand hygiene, maximal sterile barriers during insertion, skin disinfection, selection of insertion site, dressings, aseptic non-touch technique, disinfection of catheter hubs/ports, administration set management, prompt removal of catheter, antibiotic locks, systemic antibiotic prophylaxis and chlorhexidine bathing. Furthermore, it will describe different strategies that can be implemented into clinical practice to reduce infection rates. These include the use of care bundles including checklists, education and the use of CVC teams.

    2014-04-01

    Central venous catheters (CVCs) are important for the treatment of patients with cancer, especially in the perioperative and palliative care settings. These devices not only allow for the administration of chemotherapy, parenteral nutrition, and other intravenous therapies, but they may also improve the patients' quality of life by reducing the need for repeated peripheral venipunctures. Thrombotic and infectious complications are common, especially in the long-term use of CVCs. There are different types of thrombotic complications associated with CVCs, that is, a thrombotic occlusion of the catheter, a mural thrombus at the catheter tip and classical deep vein thrombosis, which occurs most frequently in the upper extremity where the majority of long-term catheters are inserted. Infections are common complications associated with CVCs. Patients with cancer who receive intensive chemotherapy and those patients who undergo hematopoietic stem cell transplantation have a markedly increased risk for insertion site and bloodstream infections. In this review, the epidemiology and risk factors that predispose patients to CVC-related thrombosis and infection are discussed. The diagnostic and therapeutic options according to the published data and the current guidelines are summarized and data for establishing primary and secondary preventative strategies are provided.

    Present guidelines recommend culturing only central venous catheter (CVC) tips from patients with suspected catheter-related bloodstream infection (CR-BSI). However, a high proportion of these suspicions are not confirmed. Moreover, CVC tip culture increases laboratory workload, and reports of colonization may be meaningless or misleading for the clinician. Our working hypothesis was that CVC tips should be refrigerated and cultured only in patients with positive blood cultures. We evaluated the effect of 6-day refrigeration of 215 CVC tips. We selected all the catheters with a significant count according to the Maki's roll-plate technique and randomly assigned them to 2 groups. In group A, the catheters were recultured after 24 h of refrigeration, and in group B, the catheters were recultured after 6 days more of refrigeration, so that the refrigeration time evaluated would be of 6 days. The yield of refrigerated CVC tips that grow significant colony counts of primary culture in group B was compared with the yield of refrigerated catheter tips in group A. The difference showed that 6-day refrigeration reduced the number of significant CVCs by 15.2%. Only 61 CVCs were obtained from patients with CR-BSI, and in most of them, blood cultures were already positive before CVC culture, so only 0.91% of the CR-BSI episodes would have been misdiagnosed as culture negative after refrigeration. Refrigeration of CVC tips sent for culture and culturing only those from patients with positive blood cultures reduce the workload in the microbiology laboratory without misdiagnosing CR-BSI.

    Background Chest radiography after central venous catheter (CVC) insertion is the main method of verifying the catheter location. Despite the widespread use of radiography for detecting catheter position, x-ray may not always be readily available, especially in the operating room. Objectives We aimed to compare contrast-enhanced ultrasonography (CEUS) and chest radiography for detecting the correct location of CVCs. Methods One hundred sixteen consecutive patients with indications for CVC before cardiac surgery were enrolled in this observational study. After catheter insertion, CEUS was performed. Portable radiography was obtained postoperatively in the intensive care unit. Sensitivity, specificity, and predictive values were determined by comparing the ultrasonography results with radiographic findings as a reference standard. Results Chest radiography revealed 16 CVC misplacements: two cases of intravascular and 14 cases of right atrium (RA) misplacement. CEUS detected 11 true catheter malpositionings in the RA, while it could not recognize seven catheter placements correctly. CEUS showed two false RA misplacements and five falsely correct CVC positions. A sensitivity of 98% and specificity of 69% were achieved for CEUS in detecting CVC misplacements. Positive and negative predictive values were 95% and 85%, respectively. The interrater agreement (kappa) between CEUS and radiography was 0.72 (P < 0.001). Conclusions Despite close concordance between ultrasonography and chest radiography, CEUS is not a suitable alternative for standard chest radiography in detecting CVC location; however, considering its high sensitivity and acceptable specificity in our study, its usefulness as a triage method for detecting CVC location on a real-time basis in the operating room cannot be ignored.

    Intravenous prostanoids are the backbone of therapy for advanced pulmonary arterial hypertension (PAH) and have improved long-term outcome and quality of life. Currently, two prostanoids are approved by the US Food and Drug administration for parenteral administration: epoprostenol (Flolan) and treprostinil (Remodulin). Chronic intravenous therapy presents considerable challenges for patients and caregivers who must learn sterile preparation of the medication, operation of the pump, and care of the central venous catheter. Patients are routinely counseled and advised regarding the risks of CR-BSIs and catheter care before central line insertion. Central line infections as well as bacteremia are well documented risks of chronic intravenous therapy and may significantly contribute to morbidity and mortality. Recent reports have suggested a possible increase in CR-BSI; therefore, the Scientific Leadership Council of the Pulmonary Hypertension Association decided to provide guidelines for good clinical practice regarding catheter care. Although data exits regarding patients with central venous catheters and the risk of blood stream infections in patients with cancer or other disorders, there is little data regarding the special needs of patients with pulmonary arterial hypertension requiring central venous access. These guidelines are extrapolated from the diverse body of literature regarding central venous catheter care.

    Catheter-related blood stream infections (CRBSI) cause significant morbidity and mortality. A retrospective study of a performance improvement project in our teaching hospital's surgical intensive care unit (SICU) showed that intensivist supervision was important in reinforcing maximal sterile barriers (MSB) use during the placement of a central venous catheter (CVC) in the prevention of CRBSI. A historical control period, 1 January 2001-31 December 2003, was established for comparison. From 1 January 2003-31 December 2007, MSB use for central venous line placement was mandated for all operators. However, in 2003 there was no intensivist supervision of CVC placements in the SICU. The use of MSB alone did not cause a significant change in the CRBSI rate in the first year of the project, but close supervision by an intensivist in years 2004-2007, in conjunction with MSB use, demonstrated a significant drop in the CRBSI rate when compared to the years before intensivist supervision (2001-2003), p < .0001. A time series analysis comparing monthly rates of CRBSI (2001-2007) also revealed a significant downward trend, p = .028. Additionally, in the first year of the mandated MSB use (2003), 85 independently observed resident-placed CVCs demonstrated that breaks in sterile technique (34/85), as compared those placements that had no breaks in technique (51/85), had more CRBSI, 6/34 (17.6%) vs. 1/51 (1.9%), p < .01. Interventions to reduce CRBSI in our SICU needed emphasis on adequate supervision of trainees in CVC placement, in addition to use of MSB, to effect lower CRBSI rates.

    Autologous peripheral blood progenitor cell (PBPC) transplantation frequently requires sequential placement and use of two separate central venous catheters: (1) a short-term, large-bore, stiff device inserted for leukapheresis, and after removal of that device, (2) a long-term, multi-lumen, flexible, Silastic catheter for administration of high-dose chemotherapy, re-infusion of hematopoietic cells, and intensive supportive care. We reviewed our recent experience with two dual-lumen, large-bore, Silastic multi-purpose ('hybrid') catheters, each of which can be used as a single device for both leukapheresis and long-term supportive care throughout the transplant process. Quinton-Raaf PermCath and Bard-Hickman hemodialysis/apheresis dual-lumen catheters were used as the sole venous access device in 112 consecutive patients who underwent autologous PBPC collection and transplantation. The catheter exit site was monitored three times a week, and lumen patency was assessed using clinical and radiologic techniques. Catheters were removed prematurely for persistent thrombus, positive blood cultures despite appropriate antibiotics, or mechanical dysfunction. There were no intra-operative or immediate post-operative complications relating to insertion. Thirty-two patients experienced catheter occlusion necessitating urokinase instillation. Persistent occlusive problems were noted in 16 patients, and in 10 patients the catheter had to be removed. Two exit site infections and 17 bacteremias occurred. Catheters had to be removed for persistent infection in two subjects and for mechanical problems in five others. Cost analysis comparing the hybrid catheters alone vs conventional devices revealed a charge of $4230 in patients with hybrid catheters vs. $7530 in those requiring a temporary non-Silastic dialysis catheter in addition to a flexible, long-term Silastic catheter. Hybrid, Silastic, dual-lumen, large-bore central venous catheters are safe, cost-effective and convenient

    Colorectal cancer patients with central venous catheters (CVC) for pharmacokinetic modulating chemotherapy (PMC) have a substantial risk of venous thromboembolism (VTE). PMC, designed as a hybrid of lower metronomic and higher shorter plasma 5-FU concentrations, has been clinically successful. To determine the effectiveness and safety of D-dimer tests and multidetector-row CT (MDCT) for diagnosis in cancer patients with suspected VTE, we carried out a clinical outcome study on PMC outpatients. Patients received a D-dimer test before and after commencing the PMC regimen. MDCT was performed additionally if the D-dimer test appeared positive or showed signs of VTE. When CT results were positive for thromboembolism, anticoagulation was started. The overall prevalence of VTE in PMC patients was 2.0% (7 of 350 patients). In this study, 34 out of 102 colorectal cancer patients gave a positive D-dimer test (33.3%). CT identified venous thrombi in 2 of the 102 patients (2.0%), mural thrombosis on catheterized veins in another 3 patients (2.9%), and endothelial hyperplasia on catheterized veins in 8 patients (7.8%). The catheters of these patients did not show any significant abnormalities. Patients with negative D-dimer tests showed no signs or symptoms of VTE. In colorectal cancer patients receiving continuous 5-FU infusion via CVC, a D-dimer test can be safely used as the primary diagnostic test for ruling out VTE. We suggest 7.0 microg/ml as the D-dimer cut-off value. Thromboprophylaxis should be considered in the patients showing values >7.0 microg/ml.

    We intended to evaluate the risk factors for catheter-related bloodstream infection (CR-BSI) with central venous (CV) catheters. For the hub of the CV line, we used three-way stopcocks in the first year of the study and closed needleless connectors (NCs) in the second year. Background factors included the age and sex of patients; the ward; the specialty service; the CV catheter and its days of placement; and the staff compounding the intravenous infusion, i.e., either nurses, who disinfect hands-free, or pharmacists using clean benches. Outcome factors included positive culture from the blood-related samples and the body temperature estimate. Of a total of 29 221 device-days in 1073 patients, positive cultures showed an overall incidence of 2.26 per 1000 device-days. Multivariate analysis showed a higher odds ratio of positive cultures for the ICU (odds ratio [OR], 4.415; 95% confidence interval [CI], 2.054-9.490]) and for CV catheter placement for more than 30 days (OR, 7.529; 95% CI, 4.279-13.247), but no significance for male sex (OR, 1.752; 95% CI, 0.984-3.119) or for pharmacists' compounding (OR, 2.150; 95% CI, 0.974-4.749). Univariate analysis showed no significance for the following factors: age more than 70 years (OR, 0.968; 95% CI 0.561-1.641), the surgery service (OR, 1.029; 95% CI, 0.582-1.818), double-lumen CV catheters (OR, 0.841; 95% CI, 0.465-1.521), or the NC (1.107; 95% CI, 0.673-1.821). We conclude that the theoretical benefit of the NC, the abolished dead space in the hub, contributed little to the outcomes of blood-related culture. The hands-free disinfection may have resulted in comparable odds ratios for the nurses and the pharmacists compounding the infusions.

    Catheter-related thrombosis (CRT) is a serious complication in hematological patients, but the risk factors for its occurrence are not well established. The study objectives were to estimate the incidence of CRT and to identify the risk factors for developing CRT in hematological patients. In a prospective setting, 104 consecutive patients with 200 insertions of central venous catheters were enrolled into the study. The patients were screened for CRT by compression Doppler ultrasound every 10-14 days. Additionally, ultrasonography was performed in the case of clinical symptoms suggesting CRT. Over the course of 6,098 catheter days of follow-up, the incidence of CRT was 13.5 %. In 18/27 cases (66.6 %), radiological evidence of CRT was preceded by clinical symptoms. However, in 9/27 (33.3 %), CRT was clinically asymptomatic. The median times to symptomatic and asymptomatic CRT were 17 (range 1-49) and 8 (range 1-16) catheter days, respectively. In univariate analysis, the risk factors for CRT were exit-site infection (ESI) (P < 0.001), two or more prior chemotherapy lines (P = 0.015), catheter-related blood stream infection (P < 0.001), and Coagulase-negative staphylococci infection (P = 0.002). In multivariate analysis, ESI (OR 5.0; 95 % CI 1.6-6.3; P = 0.006) and two or more prior chemotherapy lines (OR 3.57; 95 % CI 1.27-10.11; P = 0.015) remained significantly associated with the risk of CRT. The results of our study provide information regarding the characteristic features of the patients who are at high risk of thrombosis, for whom Doppler ultrasound screening should be considered.

    Patient: Male, 50 Final Diagnosis: Retained guidewire removal by interventional radiology Symptoms: Swelling Medication: — Clinical Procedure: Fluoroscopic retrieval of the guidewire Specialty: Critical Care Medicine Objective: Unusual setting of medical care Background: Central venous catheterization is a common tool used in critically ill patients to monitor central venous pressure and administer fluids and medications such as vasopressors. Here we present a case of a missing guide wire after placement of peripherally inserted central catheter (PICC), which was incidentally picked up by bedside ultrasound in the intensive care unit. Case Report: A 50-year-old Hispanic male was admitted to the intensive care unit for alcohol intoxication. He was managed for septic shock and required placement of a peripherally inserted central line in his left upper extremity for antibiotics and vasopressor administration. A bedside ultrasound performed by the intensivist to evaluate upper extremity swelling revealed a foreign body in the left arm. Percutaneous procedure by Interventional radiologist was required for retrieval of the guidewire. Conclusions: Guide wire related complications are rarely reported, but are significantly associated with mortality and morbidity. The use of ultrasound guidance placement of PICC lines decreases the risk of complications, provides better optimal vein selection, and enhances success. PMID:27920421

    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.

    Antimicrobial- and antiseptic-impregnated catheters are strategies recommended to prevent central venous catheter (CVC) colonisation. Few data regarding chlorhexidine/silver sulfadiazine-impregnated catheters in intensive care unit (ICU) patients have been reported. We performed a prospective, randomised study comparing the colonisation rates of chlorhexidine/silver sulfadiazine-impregnated CVCs (group 1) against standard CVCs (group 2). In order to assess catheter colonisation rates, a 4cm segment from the tips of aseptically removed catheters was cultured by the roll-plate method. In all, 109 patients were enrolled with successful catheter insertion, 51 of them in group 1 and 58 in group 2. There were no statistically significant differences between the two groups with regards to age, Sequential Organ Failure Assessment (SOFA) score, ICU admission diagnosis, infection risk, catheter insertion sites or catheter length of stay. The colonisation rates were 29.4% (15 catheters) for group 1 and 34.5% (20 catheters) for group 2 (P=0.50). Double-lumen CVCs impregnated with chlorhexidine and silver sulfadiazine were not effective in reducing the incidence of catheter colonisation in ICU patients.

    To understand the vulnerability of patients with cancer to central line-associated bloodstream infections related to tunneled central venous catheters (CVCs), patients were asked to describe their line care at home and in clinic and to characterize their knowledge and experience managing CVCs. Forty-five adult patients with cancer were recruited to participate. Patients were interviewed about the type of line, duration of use, and observations of variations in line care. They also were asked about differences between line care at home and in the clinic, precautions taken when bathing, and their education regarding line care. Demographic information and primary cancer diagnosis were taken from the patients' medical records. Patients with hematologic and gastrointestinal malignancies were heavily represented. The majority had tunneled catheters with subcutaneous implanted ports. Participants identified variations in practice among nurses who cared for them. Although many participants expressed confidence in their knowledge of line care, some were uncertain about what to do if the dressing became loose or wet, or how to recognize an infection. Patients seemed to be astute observers of their own care and offered insights into practice variation. Their observations show that CVC care practices should be standardized, and educational interventions should be created to address patients' knowledge deficits.

    Infraclavicular and internal jugular catheterization are commonly used techniques for hemodialysis access, but may at times be impeded in patients whose anatomy makes cannulation difficult. In an effort to enlarge the spectrum of alternative access sites, we evaluated the supraclavicular approach for large-bore catheters. During an 18-month period we prospectively collected data on success rate and major and minor complications of the supraclavicular access for conventional dialysis catheters as well as Dacron-cuffed tunneled devices in 175 adult patients admitted for various extracorporeal therapies and bone marrow transplantation. Two hundred eight large-bore catheters (99 conventional dialysis catheters, 63 semirigid tunneled Dacron-cuffed catheters, and 46 Hickman catheters) were successfully placed in 164 patients (success rate, 93.8%), 58 (33.1%) of whom had been previously catheterized. Complications included pneumothorax (one patient), arterial puncture (seven patients), and puncture of the thoracic duct (two patients) without sequelae. Postinsertional chest radiographs demonstrated impressive coaxial lie of most catheters. Catheter malpositions occurred only sporadically (1%). Difficulty of introducing the catheter via a placed sheath was rarely observed. There was no clinically significant evidence of catheter-induced venous thrombosis or stenosis. We conclude that the supraclavicular route is an easy and safe first approach for large-bore catheters, as well as a useful alternative to traditional puncture sites for precatheterized and anatomically problematic patients.

    We report two cases of a retained guide wire after perioperative placement of a central venous catheter during a six-month period. Case 1: A 73-year-old male was scheduled for an open cholecystectomy and hepatectomy. After induction of anesthesia, a central venous (CV) catheter was inserted via the right internal jugular vein using an ultrasound guide. Chest radiographs showed a retained guide wire in the inferior vena cava immediately after surgery, which was removed by interventional radiologist before the patient emerged from anesthesia. Case 2: A 77-year-old male was scheduled for colostomy closure. The surgeon inserted a CV catheter in the right internal jugular vein 4 days before the colostomy. Chest radiographs revealed a retained guide wire in the inferior vena cava, which was removed by interventional radiologists before the patient emerged from anesthesia. Although a retained guide wire is a rare complication, awareness of this mishap is necessary to prevent it from happening.

    This study evaluated the effects of urokinase in the prevention of central venous catheter (CVC)-related complications in children with malignancy. Fifteen patients with 16 CVCs (study group A) received an intraluminal application of urokinase (10,000 IU in each catheter lumen for 4 h) once a week. They were monitored prospectively with quantitative blood cultures and ultrasonography (color Doppler ultrasound of the great veins and echocardiography). The rate of complications was compared with that of 15 children with 19 CVCs without thromboprophylaxis, treated the previous significantly lower incidence of CVC dysfunction year (control group B). The authors found a wer incidence of CVC dysfunction (3/16 versus 13/19), no major thrombosis, fewer CVC-related bacteremias (2/16 versus 8/19), and a higher salvage of CVCs (1/16 versus 5/19 CVC removals due to persistent bacteremia) in the thromboprophylaxis group. Asymptomatic thrombosis rate was also lower (7/16 cases in group A versus 9/11 in group B when sonography was performed). No hemorrhagic complications were noted. Thromboprophylaxis with urokinase seems a safe and effective measure for reducing the rate of CVC-related complications.

    Central venous catheter (CVC)-related infections are commonly caused by Staphylococcus epidermidis that is able to form a biofilm on the catheter surface. Many studies involving biofilm formation by Staphylococcus have been published each adopting an own in vitro model. Since the capacity to form a biofilm depends on multiple environmental factors, direct comparison of results obtained in different studies remains challenging. This study characterized the phenotype (strong versus weak biofilm-producers) of S. epidermidis from CVCs in four different in vitro biofilm models, covering differences in material type (glass versus polymer) and nutrient presentation (static versus continuous flow). A good correlation in phenotype was obtained between glass and polymeric surfaces independent of nutrient flow, with 85% correspondence under static growth conditions and 80% under dynamic conditions. A 80% correspondence between static and dynamic conditions on polymeric surfaces could be demonstrated as well. Incubation time had a significant influence on the biofilm phenotype with only 55% correspondence between the dynamic models at different incubation times (48h versus 17h). Screening for the presence of biofilm-related genes only revealed that ica A was correlated with biofilm formation under static but not under dynamic conditions. In conclusion, this study highlights that a high level of standardization is necessary to interpret and compare results of different in vitro biofilm models.

    Background: The current study was designed to compare the complications and adverse effects of central venous catheter (CVC) insertion under ultrasound guidance in patients with and without coagulopathy. Materials and Methods: In this clinical trial, 59 patients who needed CVC for various reasons were enrolled. Patients were divided into two groups of those with and without coagulopathy based on complete blood count, prothrombin time, partial thromboplastin time, and international normalized ratio test results, and then, CVC was inserted with ultrasound guidance in both groups. The CVC inserting site was examined for hematoma and hemorrhage in four stages at different times. Results: There was no significant difference in the terms of demographic features, catheter lumen size (P = 0.43), and number of attempting for CVC placement (odds ratio [OR] =2.35, 95% confidence interval [CI] = 0.36–15.3, P = 0.39) between two groups. Seven out of 59 patients suffered from complications (11.9%) that the complications in coagulopathic patients were oozing (5.7%) and superficial hematoma (8.6%) while in noncoagulopathic patients were 4.2% for both complications (OR = 0.54, 95% CI = 0.09–3.07, P = 0.767). Conclusion: According to our results, it can be concluded that inserting CVC with ultrasound guidance under emergency conditions causes no serious and life-threatening complications in coagulopathic patients.

    We describe a case of a patient with a functional kidney transplant who was admitted to our department with clinically evident central vein stenosis (CVS) 7 years after the removal of a central venous catheter (CVC) from the right internal jugular vein. The catheter was used as a hemodialysis access for a 2-month period. In the interval before his last admission, the patient suffered two episodes of deep vein thrombosis. Investigation revealed heterozygosity for factor V Leiden, the most common inherited thrombophilia encountered in 5% of Caucasians, and anticoagulation treatment was started. Magnetic resonance angiography showed stenosis just after the convergence of the right subclavian vein with the internal jugular vein to the innominate vein. Transluminal angioplasty restored venous patency and right upper arm edema resolved. Coexistence of CVS, accompanied by hemodynamic changes and endothelial dysfunction, with thrombophilia fulfill all the elements of the Virchow's triad. Therefore, the patient was at great risk for central vein thrombosis, from which he was possibly protected by the early administration of anticoagulant treatment. This case indicates that CVS can be asymptomatic for several years after CVC removal and also raises the question if thrombophilia workup and investigation for CVS may be beneficial in every patient with CVC placement in order to avoid any harmful outcomes.

    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.

    Transthoracic echocardiography (TTE) is a valuable tool in the evaluation of patients with suspected air embolism. This report describes the presentation and evaluation of a critically ill woman with spontaneous air embolism occurring during a central venous catheter replacement. Bedside TTE established the diagnosis of air embolism, allowing prompt initiation of appropriate therapy. This case report highlights this uncommon but potentially life-threatening complication of central line placement and the utility of echocardiography in its evaluation.

    Central venous catheters (CVCs) are commonly used for the administration of intravenous chemotherapy in outpatient setting. Nevertheless, outbreaks of catheter-associated bloodstream infections had been reported from oncology centers. We describe a large outbreak of CVCs-associated Klebsiella oxytoca bloodstream infection, occurring in an oncology chemotherapy outpatient unit of northern Greece between October 2006 and May 2007. The outbreak involved approximately 10% of the patients with CVCs who were receiving home-based chemotherapy, and it represents the second larger outbreak of CVCs-associated BSIs due to Klebsiella oxytoca in oncology outpatient centers. We retrospectively analyzed the chain of investigations and prophylactic/diagnostic measures taken to eradicate the infection: (1) patients' chart audit, (2) estimation of the infection among asymptomatic patients, (3) implementation of the level of awareness of medical and paramedical personnel, (4) collection of samples from environment, medications and infusion materials, (5) critical appraisal of chemotherapeutical schemes and (6) cooperation with peripheral institutions. The isolation of Klebsiella oxytoca in a chemotherapy solution (infusional 5-FU in dextrose 5% solution within a 48 h pump) from a peripheral General Hospital and the prompt transmission of the data to the chemotherapy center played a key role for the management of the infection cluster. This is the first report that evidenced the detection of Klebsiella oxytoca within a chemotherapeutical preparation. Data transmission from peripheral hospitals to the central institution resulted in an important feedback that allowed a better estimation of the infection cluster and more tailored actions for the eradication of the infection.

    Central venous access plays an important role in the management of an ever-increasing population of patients ranging from those that are critically ill to patients with difficult clinical access. Interventional radiologists are key in delivering this service and should be familiar with the wide range of techniques and catheters now available to them. A comprehensive description of these catheters with regard to indications, technical aspects of catheterization, success rates, and associated early and late complications, as well as a review of various published guidelines on central venous catheter insertion are given in this article.

    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(r) 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. PMID:23904810

    Objective: To evaluate the efficacy and safety of the treatment of traumatic hemothorax by closed pleural drainage using a central venous catheter (CVC), compared with using a conventional chest tube. Methods: A prospective controlled study with the Ethics Committee approval was undertaken. A total of 407 patients with traumatic hemothorax were involved and they were randomly assigned to undergo closed pleural drainage with CVCs (n=214) or conventional chest tubes (n=193). The Seldinger technique was used for drainage by CVC, and the conventional technique for drainage by chest tube. If the residual volume of the hemothorax was less than 200 ml after the daily volume of drainage decreased to below 100 ml for two consecutive days, the treatment was considered successful. The correlative data of efficacy and safety between the two groups were analyzed using t or chi-squared tests with SPSS 13.0. A P value of less than 0.05 was taken as indicating statistical significance. Results: Compared with the chest tube group, the operation time, fraction of analgesic treatment, time of surgical wound healing, and infection rate of surgical wounds were significantly decreased (P<0.05) in the CVC group. There were no significant differences between the two groups in the success rate of treatment and the incidence of serious complications (P>0.05), or in the mean catheter/tube indwelling time and mean medical costs of patients treated successfully (P>0.05). Conclusions: Management of medium or large traumatic hemothoraxes by closed thoracic drainage using CVC is minimally invasive and as effective as using a conventional large-bore chest tube. Its complications can be prevented and it has the potential to replace the large-bore chest tube. PMID:22205619

    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 <0.05). Compared with gelatin sponge and alginate dressing hemostatic effect, The difference was not statistically significant. (2) Tube maintenance cost: Puncture point using gelatin sponge, The local maintenance costs of the 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.

    Purpose Long-term central venous catheters (CVCs) are often used in patients with cancer to facilitate venous access to administer intravenous fluids and chemotherapy. CVCs can also be a source of bloodstream infections, although this risk is not well understood. We examined the impact of long-term CVC use on infection risk, independent of other risk factors such as chemotherapy, in a population-based cohort of patients with cancer. Patients and Methods We conducted a retrospective analysis using SEER-Medicare data for patients age > 65 years diagnosed from 2005 to 2007 with invasive colorectal, head and neck, lung, or pancreatic cancer, non-Hodgkin lymphoma, or invasive or noninvasive breast cancer. Cox proportional hazards regression was used to examine the relationship between CVC use and infections, with CVC exposure as a time-dependent predictor. We used multivariable analysis and propensity score methods to control for patient characteristics. Results CVC exposure was associated with a significantly elevated infection risk, adjusting for demographic and disease characteristics. For patients with pancreatic cancer, risk of infections during the exposure period was three-fold greater (adjusted hazard ratio [AHR], 2.93; 95% CI, 2.58 to 3.33); for those with breast cancer, it was six-fold greater (AHR, 6.19; 95% CI, 5.42 to 7.07). Findings were similar when we accounted for propensity to receive a CVC and limited the cohort to individuals at high risk of infections. Conclusion Long-term CVC use was associated with an increased risk of infections for older adults with cancer. Careful assessment of the need for long-term CVCs and targeted strategies for reducing infections are critical to improving cancer care quality. PMID:24982458

    Introduction Peripherally inserted central venous catheters (PICCs) may adversely impact future successful arteriovenous fistulae (AVF). As part of a quality improvement project, the performance of tunneled small bore tunneled central venous catheters (TSB-CVCs), as alternatives to PICCs, was evaluated. Methods A retrospective observational study, involving individuals ≥18 years of age who underwent TSB-CVC placement by Interventional Radiology at Mayo Clinic, Rochester, MN between 1/1/2010 and 8/30/2013. Findings The study cohort included 92 patients with a median age of 55 (46-67) years, who underwent 108 TSB-CVC placements. Baseline renal disease was present in 71% (77/108). Most TSB-CVCs were placed in hospitalized patients (94%; 102/108); five French in diameter (61%; 66/108) and located in an internal jugular vein (84%; 91/108). Median catheter indwelling time was 20 (11-43) days (n = 84). TSB-CVC-related bloodstream infection, deep venous thrombosis (DVT), and superficial venous thrombosis (SpVT) rates per line were 0.009 (1/108), 0.018 (2/108), and 0.009 (1/108), respectively. Venous outcomes in a subgroup of 54 patients, who had documented PICC placements (n = 161) in addition to TSB-CVC (n = 58) were compared. TSB-CVC-DVT rate was lower than the PICC-DVT rate (0.017 [1/58] vs. 0.106 per line [17/161]; P = 0.04). The TSB-CVC-SpVT rate was not different from the PICC-SpVT rate (0 [0/58] vs. 0.037 [6/161] per line; P = 0.14). Discussion TSB-CVCs demonstrated an excellent safety profile in our study. These catheters should be preferentially utilized for arm vein preservation in advanced kidney disease. Their impact on future AVF success needs further evaluation.

    Pediatric central venous catheter (CVC) placement is useful but associated with complications such as cardiac tamponade. We aimed to identify risk factors for death in cardiac tamponade. Published articles on pediatric CVC-associated cardiac tamponade were obtained by searching PubMed and Google and retrospectively reviewed to analyze risk factors for death. Factors examined for their effect on mortality risk included patient age, weight, CVC size, days from CVC insertion to tamponade occurrence, substances administered, insertion site, treatment, CVC material, and initial CVC tip position. Of 110 patients reported in 62 articles, 69 survived and 41 died. Among survivors, 55 of 69 patients were treated; among deaths, only 7 of 38 (OR 537.9, 95% CI 29.3-9,877, p < 0.0001). Multiple regression analysis in 44 cases showed that treatment (p < 0.0001) and initial CVC tip position (p = 0.020) were independent predictive factors related to improved cardiac tamponade survival. Past studies have mainly discussed how to avoid pediatric cardiac tamponade; by contrast, the present study focused on how to avoid deaths. The findings of this review suggest that cardiac tamponade survival is better when tamponade is detected early and treated promptly and might be affected by initial CVC tip position.

    We report a case of a 51-year-old male who developed frequent nonsustained episodes of monomorphic ventricular tachycardia after being diagnosed with bioprosthetic aortic valve endocarditis and treated with intravenous antibiotics. A peripherally inserted central venous catheter (PICC) had been placed without complication less than 24 hours prior to the episodes. Ventricular tachycardia (VT) occurred during the night, while sleeping, when he assumed a right lateral decubitus position with abduction of the right arm and placement of the forearm under his head. VT occurred repeatedly when such position was assumed again upon request, and it would terminate immediately when sitting upright. The PICC was repositioned in the superior vena cava without further VT. He was discharged home the same day and underwent successful aortic valve replacement 2 months later. Position-dependent VT related to PICC requires careful history taking and PICC repositioning to make the diagnosis. X-ray in different patient positions during PICC placement can be considered to evaluate for ventricular migration. PMID:27826374

    Central venous catheters (CVC) are frequently used in intensive care units (ICU), with a low incidence of complications, most of them being of mechanical origin and occurring during the insertion of the catheter. To avoid such complications, "ultrasound guidance" and "ultrasound assistance" are recommended. Nevertheless, even with trained and experienced physicians, mechanical complications of IJV access such as carotid punctures are still reported. We report the case of a 75-year-old woman, admitted into the ICU for CVC insertion due to impossibility of peripheral venous access. About 12 hours after the procedure, the patient presented a neurological deficit. The cervical and thoracic CT scan showed a transfixing path of the catheter from the left IJV into the left common carotid artery, with distal extremity of the catheter localized in the ascending aorta. The catheter was removed, and thereafter the neurological deficit immediately and definitely disappeared. Onset of a neurological deficit after CVC insertion into the IJV, regardless the time of occurrence after the procedure, should suggest complication due to the CVC insertion, even if procedure was uneventful and chest radiography confirmed the apparent accurate position of CVC.

    Interdisciplinary team (IDT) rounds were initiated in the intensive care unit (ICU) in June 2010. All catheters were identified by location, duration, and indication. Catheters with no indication were removed. Data were collected retrospectively on catheter days and associated infections in a 20-month period before and after intervention with an aggregate of 19 207 ICU days before and 23 576 ICU days after institution of rounds. Results showed a statistically significant decrease in the number of indwelling urinary catheter (IUC) days (5304 vs 4541 days, P = .05) and catheter-associated urinary tract infection rates (4.71 vs 1.98 infections/1000 ICU days, P < .05). Central line days statistically increased after IDT rounds (3986 vs 4305 days, P < .05) but the catheter-related bloodstream infection rate trended down (3.5 vs 1.6 infections/1000 ICU days, P = .62). This analysis suggests that IDT rounds may have an impact on reducing the number of IUC days and associated infections.

    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 based on molecular methods

    Catheter-related central thrombosis is a rare complication of long-term central line. We describe the case of an asymptomatic boy who was diagnosed a calcified thrombus in right atrium eight years after the removal of a long-term central venous device. Although the most appropriate therapeutic approach for managing floating right heart thrombi remains to be determined, surgical removal is an effective and safe procedure for calcified long-standing thrombus and it is to be preferred in elective conditions especially in young asymptomatic patients without hemodynamic involvement, that are at low risk of surgery-related morbidity and mortality.

  10. Convective Leakage Makes Heparin Locking of Central Venous Catheters Ineffective within Seconds: Experimental Measurements in a Model Superior Vena Cava

    Central venous catheters (CVCs), placed in the Superior Vena Cava (SVC) for hemodialysis or chemotherapy, are routinely filled while not in use with heparin, an anticoagulant, to maintain patency and prevent thrombus formation at the catheter tip. The heparin-locking procedure, however, places the patient at risk for systemic bleeding, as heparin is known to leak from the catheter into the blood stream. We provide evidence from detailed in-vitro experiments that shows the driving mechanism behind heparin leakage to be convective-diffusive transport due to the pulsatile flow surrounding the catheter. This novel mechanism is supported by experimental planar laser induced fluorescence (PLIF) and particle image velocimetry (PIV) measurements of flow velocity and heparin transport from a CVC placed inside a model SVC inside a pulsatile flow loop. The results predict an initial, fast (< 10s), convection-dominated phase that rapidly depletes the concentration of heparin in the near-tip region, the region of the catheter with side holes. This is followed by a slow, diffusion-limited phase inside the catheter lumen, where the concentration is still high, that is insufficient at replenishing the lost heparin concentration in the near-tip region. The results presented here, which are consistent with previous in vivo estimates of 24-hour leakage rates, predict that the concentration of heparin in the near-tip region is essentially zero for the majority of the interdialytic phase, rendering the heparin locking procedure ineffective.

    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.

    Spinal infections are a rare yet serious metastatic complication of bacteremia among patients with long-term central venous catheters (CVCs) for which clinicians must remain vigilant. We performed a retrospective review of all cases of spinal infection occurring in the context of a CVC for long-term parenteral nutrition (PN) managed in our department between January 2010 and October 2013, a cohort of 310 patients over this time period. Six patients were identified (mean age, 65 years; 5 male). One hundred percent of patients presented with spinal pain (5/6 cervical, 1/6 thoracic). Organisms were cultured from the CVC in 5 of 6 patients. In all cases, the white blood cell count was normal, and in 5 of 6, C-reactive protein was normal. All diagnoses were confirmed on magnetic resonance imaging (MRI), and in 3 of 6 cases, an MRI was repeated (on the advice of neurosurgical colleagues) to confirm resolution of changes after a period of antimicrobial therapy. There was no clear correlation between duration of PN or number of days following CVC insertion and onset of infection. The CVC was replaced in 4 of 6 patients at the time of diagnosis, delayed removal in 1 of 6, and salvaged in the remaining case. Although rare, a high index of suspicion is needed in patients receiving long-term PN who present with spinal pain. Peripheral inflammatory markers may not be elevated. MRI should be performed and patients should be treated with antibiotics alongside involvement of local microbiology and neurosurgical teams. Multidisciplinary discussion on CVC salvage in these cases is important, especially in cases of challenging vascular anatomy.

    Antimicrobial releasing biomaterial coatings have found application for instance in the fixation of orthopedic joint prostheses and central venous catheters. Most frequently, the release kinetics is such that antimicrobially-effective concentrations are only reached within the first days to weeks after implantation, leaving no local antimicrobial release available when a biomaterial-associated infection occurs later. Here we compare the ad libitum release of chlorhexidine and silver-sulfadiazine from a central venous catheter with their release from a new, on-demand release coating consisting of a temperature-sensitive copolymer of styrene and n-butyl (meth)acrylate. The copolymer can be loaded with an antimicrobial, which is released when the temperature is raised above its glass transition temperature. Ad libitum release of chlorhexidine and silver-sulfadiazine from a commercially-purchased catheter and associated antimicrobial efficacy against Staphylococcus aureus was limited to 16days. Consecutive temperature-triggers of our on-demand coating yielded little or no antimicrobial efficacy of silver-acetate release, but antimicrobially-effective chlorhexidine concentrations were observed over a time period of 60-80days. This attests to the clear advantage of on-demand coatings above ad libitum releasing coatings, that may have released their antimicrobial content before it is actually needed. Importantly, glass transition temperature of chlorhexidine loaded copolymers was lower (48°C) than of silver loaded ones (61°C), facilitating their clinical use.

    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.

  16. Fluid mechanics and clinical success of central venous catheters for dialysis--answers to simple but persisting problems.

    Over 60% of patients initiating chronic hemodialysis in the United States have a chronic central venous catheter (CVC) as their first blood access device. Although it would be better if these patients started dialysis with fistulas, the CVC is used because it is a reliable and relatively safe method for obtaining blood access over a period of months. Drawing blood from a vein at 300-400 ml/minute is a relatively delicate and somewhat unpredictable process, and there is always a tendency for the vein wall to draw over the arterial tip and obstruct flow. Several methods have been employed to minimize this problem and maximize blood flow, and differing catheter designs have resulted. With all of the different catheter designs now on the market, it is natural to ask what is the logic of different designs. Moreover, in the absence of many direct comparative studies it is natural to ask whether one design is really better than another. There is some misinformation regarding catheter design and function. The following is a list of 10 frequently asked questions In this review, the hydraulic features of CVC are discussed and explained, and logical answers are provided for the following questions: 1. Why do ''D'' catheters flow better than concentric or side by side catheters? 2. Why are all catheters about the same diameter? Does making them bigger really decrease the resistance to flow? 3. Why might a split tip catheter flow better than a solid body catheter? 4. What happens to injections of lock solution at catheter volume? 5. What's better-numerous side holes or none? 6. Why does blood rise into some internal jugular catheters over time, displacing the lock solution? 7. How can a little kink (or stenosis) decrease flow so much? 8. Where should the tips be placed-superior vena cava or right atrium? 9. Which is really better, splitsheath or over-the-wire placement? 10. Which dialysis access has a lower complication rate--CVC or arteriovenous (AV) graft? There remain

    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.

    The most important targets of hospital-acquired infection control are to reduce the incidence of surgical-site, catheter-related, and ventilator-associated infections. In this report, we address previously presented infection-control strategies for central venous (CV) line catheterization, using a CV catheter-related infection surveillance system. Data concerning CV catheter insertion were collected from all facilities in our 650-bed hospital, excluding the operating and hemodialysis wards. Collected data included the insertion method, purpose, length of catheter inserted, duration of catheterization, infection rate, and complication rate. Catheter-related infection was diagnosed based on bacteriological examinations from blood cultures. The total number of catheterizations was 806 a year, and average duration of catheterization was 9.8 days. The purpose of catheterization was nutritional support in 210 cases, hemodialysis in 96 cases, cardiac support in 174 cases, and other treatments in 260 cases. In 66 cases, the purpose of CV catheter was not specified. The rate of positive cultures was 7.1%, and complications other than infection occurred in 0.5%. The main causative organisms were methicillin-resistant Staphylococcus aureus (MRSA) in 38.6%, coagulase-negative Staphylococcus epidermidis (CNS) in 33.3%, and S. aureus in 12.3% of infections. Infection rates were 3.8 per 1000 catheter-days in subclavian, 6.1 in jugular, and 15.7 in femoral vein catheterization. In high-risk departments (intensive care unit [ICU] and emergency departments) the infection rate was 5.4 for subclavian and 10.2 for jugular catheterization, whereas it was 3.6 for subclavian and 4.6 for jugular catheterization in noncritical-care departments. Considering complications such as pneumothorax, CV catheterization of the jugular vein is recommended in certain situations.

    Background: Proper placement of central venous catheter (CVC) tip could reduce early and late catheter-related complications. Although the live fluoroscopy is standard of care for placement of the catheter, it is not available in many centers. Therefore, the present study evaluated the sensitivity and specificity of bedside chest X-ray (CXR) for proper positioning of the catheter tip. Materials and Methods: A total of 82 adult patients undergoing elective placement of tunneled CVC were enrolled in this study during 2010-2012. The catheter tip position was evaluated by postoperative bedside chest radiographs as well as trans-thoracic echocardiogram as definite diagnostic tool. The catheter position was considered correct if the tip was positioned in the right atrium both in CXR or echocardiography. Finally, CXRs interpreted by expert radiologist. Thus findings were compared by echocardiography. Sensitivity, specificity, accuracy, positive, and negative predictive values were calculated. Data were analyzed using SPSS version 16 (SPSS Inc., Chicago, IL), and P < 0.05 considered as significant. Results: The patients were 57.37 ± 18.91 years of age, weighed 65.79 ± 15.58 kg and were 166.36 ± 9.91 cm tall. Sensitivity and specificity of CXR for proper catheter tip position were 74.3% and 58.3%, respectively. Positive and negative predictive values were 91.2% and 28%. In addition accuracy, positive likelihood ratio, and negative likelihood ratio were 71.9%, 1.78, and 2.27 respectively. Conclusion: Bedside CXR alone does not reliably predict malpositioning after CVC placement. PMID:25767527

    Objective: To compare the efficacy of two concentrations of heparin to clear the lumen of in vitro clotted neonatal peripherally inserted central catheters (PICCs). Methods: This is an in vitro, experimental quantitative study of 76 neonatal 2.0-Fr PICCs coagulated in vitro. The catheters were divided into two groups of 38 PICCs each. In both groups an infusion of low molecular weight heparin was administered with a dose of 25IU/mL for Group 1 and 50IU/mL for Group 2. The negative pressure technique was applied to the catheters of both groups at 5, 15 and 30min and at 4h to test their permeability. Kaplan-Meier survival analysis was used to verify the outcome of the groups according to time intervals. Results: The comparison between both groups in the first 5min showed that more catheters from Group 2 were cleared compared to Group 1 (57.9 vs. 21.1%, respectively). Kaplan-Meier survival analysis showed that less time was needed to clear catheters treated with 50IU/mL of heparin (p<0.001). Conclusions: The use of low molecular weight heparin at a concentration of 50IU/mL was more effective in restoring the permeability of neonatal PICCs occluded in vitro by a clot, and the use of this concentration is within the safety margin indicated by scientific literature.

    Current clinical practice is characterised for importance of the patient's quality of life and the need to reduce the costs of their treatment. We search intravenous therapy alternatives that meet the needs of the patient, reducing the complications associated with the use of venous catheters. Scientific evidence shows that there are midline venous catheters that offer patients and professionals the possibility of extending the duration of infusion therapy, using more venous compatibility materials, and with less risk of infection. The Midlines are becoming in a safe an efficient device for intravenous therapy, continuous and intermittent infusion, provided the necessary care by expert nurses. Midline catheters are peripheral venous access devices between 3 to 10 inches in length (8 to 25 cm). Midlines are usually placed in an upper arm vein, such as the brachial or cephalic, and the distal extreme ends below the level of the axillary line. Midlines catheters implanted in the cephalic or deep basilica veins get more blood flow. This large blood volume justifies the lower risk of mechanical or chemical phlebitis. Midlines are routinely used for two to six weeks. Due that the extrem of these catheters does not extend beyond the axillary line, there are limitations for its use: type of infused drugs, velocity of infusion, etc. In general, solutions that have pH 5 to 9, or an osmolarity less than 500 mOsm are appropriate for infusion through a Midline. Its use is recommended in case of treatments over 7 days with low irritant capacity fluids. According to the Infusion Nurses Society's standards of practice, Midline catheters are appropriate for all intravenous fluids that would normally be administered through a short peripheral IV Importantly, due that the catheter does not pass through the central veins, Midlines can be placed without a chest X-ray to confirm placement. For certain situations, Midlines are suitable for acute units and even for care home settings

    Purpose: Despite some advantages to their use, long-term central venous catheters (CVCs) are associated with complications for patients who require chemotherapy. Understanding of these risks in commercially insured populations is limited. This information can inform medical policies that ensure the appropriate use of venous access devices. This study's objectives were to assess the extent of variation in use of long-term CVCs in a cohort of commercially insured women with breast cancer, and to assess risks of associated complications. Methods: Retrospective cohort analysis was conducted using health insurance claims between January 2006 and October 2013. The cohort included commercially insured women age ≥ 18 years diagnosed with breast cancer who received infusion chemotherapy (N = 31,047). We conducted matched and case-mix adjusted Cox proportional hazard modeling to assess differences in bloodstream infections and thrombovascular complications between patients using long-term CVCs and those using temporary intravenous catheters. Results: Approximately two thirds of the cohort had a long-term CVC, although rates varied across regions (57% to 75%), health plans (65% to 70%), and insurance coverage (63% to 68%). After propensity score matching, the adjusted hazard ratio for infection was 2.70 (95% CI, 2.31 to 3.16) and thrombovascular complications, 2.61 (95% CI, 2.33 to 2.93) in patients with long-term CVCs compared with those with temporary intravenous catheters. Conclusion: Although long-term CVCs may have benefits, they are associated with increased morbidity. Regional and health plan variation in long-term CVC insertion suggests that some of their use reflects provider- or institution-driven variation in practice. Evidence-based guidelines and tools may help decrease discretionary use of long-term CVCs. PMID:26265170

    Bilateral total knee replacement (BTKR) has been associated with a higher incidence of fat embolism (FES) compared to single knee replacement. Consequently, intraoperative monitoring with a pulmonary artery catheter (PAC) has been recommended. This study compares clinical outcome in BTKR patients monitored with central venous pressure versus PAC. A retrospective chart review of 249 consecutive patients undergoing BTKR, 132 of whom had PAC insertion versus 117 who had central line insertion, over a 1-year period were included in the study. Their medical records were reviewed for co-morbidities, baseline characteristics, and type of intraoperative monitoring. Need and duration for postoperative monitoring in the postoperative care, length of hospital stay (LOHS), signs of fat embolism, development of arrhythmias, and respiratory failure were all outcome measures. A total of four patients (1.6%) had FES as per Schonfeld criteria. One of these patients died within 48 h of surgery. They all had PAC monitoring intraoperatively. Pulmonary artery pressure (PAP) remained unchanged during surgery which raises doubt as to the clinical utility and advisability of the use of PAC’s in this setting. There was no statistically significant difference in cardiac or pulmonary complications, or LOHS between the two groups. Central venous pressure monitoring appears to be sufficient in patients undergoing BTKR. PMID:19002531

    Catheter-related blood stream infection (CR-BSI) in patients with pulmonary hypertension (PH) receiving intravenous iloprost via an indwelling central line has previously not been fully described. Recent studies have suggested a link between the pH of prostanoid infusions and the rate and nature of CR-BSI. We have investigated CR-BSI in patients receiving intravenous iloprost at our unit. Databases and hospital records were interrogated for all patients receiving intravenous iloprost between September 2007 and June 2012. Fifty-nine patients received intravenous iloprost via an indwelling central catheter with a total of 23,072 treatment days. There were 15 episodes of CR-BSI, identified using a systematic screening protocol, involving 11 patients giving an overall CR-BSI rate of 0.65/1,000 treatment days. CR-BSI rate for Gram-positive organisms was 0.26/1,000 treatment-days and for Gram-negative organisms was 0.39/1,000 treatment-days. The pH of iloprost in typical dosing regimens was comparable to the pH used in standard-diluent treprostinil and dissimilar to alkaline epoprostenol infusions. The proportion of Gram-negative CR-BSI was similar to that reported for standard-diluent treprostinil. CRP was normal on admission in 33 % of cases of confirmed CR-BSI and remained normal in 13 % of cases. CR-BSI rates with intravenous iloprost are comparable to those observed for other prostanoids. The high proportion of Gram-negative organisms observed and the neutral pH of iloprost infusions support the previously hypothesised link between pH and antimicrobial activity. Although usually elevated during a CR-BSI, CRP may be normal in early infection and a normal result cannot completely exclude infection.

    Central venous catheterization is widely used in neonatal intensive care units to support tiny preterm babies. Pericardial effusion (PCE) and cardiac tamponade are uncommon but potentially fatal complications of percutaneous, umbilical and surgically placed central venous catheters related to intracardiac position or migration. This report describes a case of PCE arising from fluid infused via umbilical venous catheter. The case study highlights two important aspects: one, occurrence of PCE in a baby with satisfactory position of the umbilical catheter, and second, the life-saving application of basic echocardiography by bedside caregivers for the diagnosis and treatment of this critical condition.

    Objective To evaluate the cost-effectiveness, from the funding body's point of view, of real-time ultrasound-guided central venous catheter insertion compared to the traditional method, which is based on the external anatomical landmark technique. Methods A theoretical simulation based on international literature data was applied to the Brazilian context, i.e., the Unified Health System (Sistema Único de Saúde - SUS). A decision tree was constructed that showed the two central venous catheter insertion techniques: real-time ultrasonography versus external anatomical landmarks. The probabilities of failure and complications were extracted from a search on the PubMed and Embase databases, and values associated with the procedure and with complications were taken from market research and the Department of Information Technology of the Unified Health System (DATASUS). Each central venous catheter insertion alternative had a cost that could be calculated by following each of the possible paths on the decision tree. The incremental cost-effectiveness ratio was calculated by dividing the mean incremental cost of real-time ultrasound compared to the external anatomical landmark technique by the mean incremental benefit, in terms of avoided complications. Results When considering the incorporation of real-time ultrasound and the concomitant lower cost due to the reduced number of complications, the decision tree revealed a final mean cost for the external anatomical landmark technique of 262.27 Brazilian reals (R$) and for real-time ultrasound of R$187.94. The final incremental cost of the real-time ultrasound-guided technique was -R$74.33 per central venous catheter. The incremental cost-effectiveness ratio was -R$2,494.34 due to the pneumothorax avoided. Conclusion Real-time ultrasound-guided central venous catheter insertion was associated with decreased failure and complication rates and hypothetically reduced costs from the view of the funding body, which in this

    Catheter-related bloodstream infection (CRBSI) is an infectious disease requiring special attention. It is a common cause of nosocomial infections; catheter insertion into the central veins particularly increases the risk of infection (CLA-BSI: central line-associated bloodstream infection). We examined the relationship between the number of bacterial colonies cultured from shredded central venous catheter (CVC) tips and from blood cultures in our hospital from 2011 to 2012. Coagulase-negative staphylococci topped the list of microbe isolated from the CVC tip culture, followed by Pseudomonas aeruginosa, Staphylococcus aureus, and Candida spp. S. aureus and Candida spp., with growth of over 15 colony-forming units in the CVC tip culture, were also detected at high rates in the blood culture. However, gramnegative bacilli (Enterobacteriaceae and P. aeruginosa) did not show a similar increase in colony number in the CVC tip culture. Because microbes adhering to shredded catheter tips are readily detected by culture, this method is useful as a routine diagnostic test. In addition, prompt clinical reporting of the bacterial number of serious CLA-BSI-causing S. aureus and Candida spp. isolated from CVC tips could contribute to earlier CLA-BSI diagnosis.

    Catheters are the leading source of bloodstream infections in critically ill patients. Because the clinical signs of infection are nonspecific, such infections are overly suspected, which results in unnecessary removal of catheters. A conservative approach might be attempted in mild infections, whereas catheters should always be removed in cases of severe sepsis or septic shock. Nowadays, comprehensive unit-based improvement programs are effective to reduce catheter-related bloodstream infections (CR-BSIs). Rates of CR-BSI higher than 2 per 1000 catheter-days are no longer acceptable. A locally adapted checklist of preventive measures should include cutaneous antisepsis with alcoholic preparation, maximal barrier precaution, strict policy of catheter maintenance, and ablation of useless catheters. Antiseptic dressings and, to a lesser extent, antimicrobial-coated catheters, might be added to the prevention strategies if the level of infections remains high despite implementation of a prevention program. In the case of CR-BSI in intensive care units (ICUs), the catheter should be removed. In the case of persistence of fever or positive blood cultures after 3 days, inadequate antibiotic therapy, endocarditis, or thrombophlebitis should be ruled out.

    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 <797> 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.

    In our neonatal intensive care unit, the incidence density of infections related to central catheters, assessed retrospectively over 2 years, exceeded that described in the literature. To reduce this incidence density, clinical practice guidelines were implemented for the insertion and maintenance of central lines. The purpose of this study was to evaluate the impact of the protocol on the incidence density and the incidence rate of nosocomial bloodborne infections. This was a prospective study in a neonatal intensive care unit of the Fort-de-France University Hospital over 17 months, which included all premature infants with a central line. We studied the adherence to the protocol, possible complications related to the protocol, the characteristics of the population, the incidence rate, and the density of specific central catheter-related infections. There were 111 children, 122 catheters, and 2575 catheter days during period 1 and 101 children, 125 catheters, and 1631 catheter days during period 2. Gestational age and birth weight were significantly lower in period 2 (29.6±2.3 GW vs 27.3±1.9, P=0.001; 1239±379g vs 915±175g, P<0.001) and the catheterization duration differed between the 2 periods (20±11 days vs 13±6 days, P<0.0001). A trend for a lower incidence density of infection was observed in the second period (16 per 1000 catheter days vs 10 per 1000 catheter days, P=0.06). Although the 2 groups' baseline characteristics were different, this study suggests a positive impact of clinical practice guidelines for the insertion and maintenance of central venous catheters on the incidence of nosocomial infections related to central catheters.

    To facilitate therapy of central venous catheter-related Gram-positive bacterial infection in patients who require total parenteral nutrition (TPN) therapy, we studied the stability of vancomycin in a commonly used TPN solution (V-TPN) at final concentrations of 0.5 mg/mL and 1.0 mg/mL and in heparin (100 U/mL in 0.9% NaCl) at 25 micrograms/mL (V-H). Vancomycin concentrations in V-TPN and V-H after storage at 4 degrees C over 35 and 14 days, respectively, were stable (within 10% of the prestorage vancomycin concentration). After 14 days at 4 degrees C heparin activity in V-H solution was 100 +/- 4% of that noted initially. Vancomycin remained stable (100 +/- 6% of the original vancomycin concentration) when the previously refrigerated V-TPN was held for an additional 24 hours at 22 degrees C. When the previously refrigerated V-H was held for an additional 24 hours at 37 degrees C, vancomycin concentrations decreased to 78 +/- 9% of the baseline concentrations (p less than .001). The stability of vancomycin in this TPN solution allows the daily dose of vancomycin to be mixed with the solution and then infused over 10 hours. As shown with pharmacokinetic modeling, this form of therapy will achieve serum vancomycin concentrations within the therapeutic range throughout a 24-hour period. The relative stability of vancomycin in a heparin line-flush solution allows vancomycin concentration in the lumen of the catheter to be maintained at greater than or equal to 15 micrograms/mL during the interval between catheter flushing and the subsequent TPN infusion. A simplified method of administering vancomycin to patients receiving concurrent TPN is possible.

    We report the results of a 4-years-experience with Hickman-Broviac double lumen silicone catheters. The catheters were inserted in 51 dialysed and nondialysed children. Forty three catheters were placed for temporary or permanent dialysis access, 2 in patients for plasmapheresis, 4 in severely burnt patients, and 2 in neonates with the "short gut" syndrome. The youngest patient was 7 days old and the eldest 14.5 years (mean age 5.4 years). The catheters were implanted by open surgery into the right atrium through the right (92%) or left internal jugular vein (8%) in more than 80% of patients. Ten catheters were implanted in the femoral vein (three through the saphenous vein: in a patient with extensive burns in the thorax and neck area, and in seven patients with acute renal failure and high risk for anaesthesia). The complications, except the insufficient flow, were fewer and less dangerous than those reported in literature. Therefore, we strongly recommend insertion of these catheters as the method of choice for immediate vascular access in children in whom the creation of conventional vascular access is difficult or impossible, as well as in patients in whom provision of long- term intravenous nutrition or medication is essential.

    Considerable numbers of patients undergo central venous catheterization (CVC) under mechanical ventilation. We hypothesized that the return of spontaneous breathing and tracheal extubation could be associated with distal CVC tip migration towards intracardiac positions due to decreasing intrathoracic pressures and subsequent readjustment of mediastinal organs. Patients scheduled for cardiac surgery were randomized for right or left internal jugular vein (IJV) CVC placement under general anesthesia and mechanical ventilation. CVC tips were positioned at the cavoatrial junction and measured at the time of placement, postoperatively under mechanical ventilation, and after tracheal extubation until 48 h after surgery. Measurement methods included intravascular electrocardiography (ECG) P-wave amplitude, transesophageal echocardiography, and chest radiography (CXR). Out of 70 patients, 60 were eligible for final statistical analysis (31 right and 29 left IJV CVC). According to ECG interpretation, CVC tip positions remained below the pericardiac reflection point in the distal superior vena cava over the course of the three measurement intervals. The ECG revealed significant proximal migration of CVC tips from the time of placement to the time of tracheal extubation (1.19 ± 0.55 vs. 0.62 ± 0.31 mV; P < 0.001). A CXR using CVC tip to carina distances revealed no significant tip migrations in the time between postoperative assessment and following tracheal extubation (5.1 ± 1.7 vs. 5.3 ± 1.5 cm; P = 0.196). In patients with CVCs positioned at the cavoatrial junction, tracheal extubation was not associated with significant postoperative CVC tip malposition, but tended to undergo proximal migration. This trend should be considered particularly in left-sided thoracocervical puncture approaches to avoid unfavorable CVC tip positions.

    Our objective was to compare mortality, epidemiology, and morbidity in hospitalized patients with candidemia which was both related and unrelated to the central venous catheter (CVC). This was a monocentric, retrospective cohort study of candidemia. The sample consisted of 103 patients with laboratory-confirmed nosocomial candidemia hospitalized between 2006 and 2013 in a tertiary care public hospital. We included 65 (63.1 %) patients (24 in the CVC-positive group, 41 in the CVC-negative group). Demographic data and risk factors were recorded using a structured case report form. In the group of candidemia associated to the CVC, survival at day 50 was 58.6 ± 11.9 %, compared to 26.5 ± 8.9 % for the CVC-negative group (p-value = 0.012); the hazard ratio of death was 0.38 (95 % confidence interval 0.17-0.85, p-value = 0.019). Compared with the CVC-positive patients, CVC-negative patients were often colonized with yeast (41.5 % vs. 16.7 %, p-value = 0.041), had a shorter previous in-hospital stay (20 days vs. 34 days, p-value = 0.023), and were more severely ill (severe sepsis 85.4 % vs. 58.3 %, p-value = 0.016). In this study, when the origin of candidemia was not the CVC, patients were more seriously ill, had a higher mortality rate, and the removal of the catheter seemed to lead to disappointing results. It would be useful to explore the impact of retention of the CVC on survival in the CVC-negative patients, where the CVCs are essential to treating these patients.

    We present four patients in whom bedside placement of a central venous catheter was complicated by entrapment of a J-tip guidewire by a previously placed vena cava (VC) filter. Two Venatech filters were fragmented and displaced into the superior VC or brachiocephalic vein during attempted withdrawal of the entrapped wire. Two stainless-steel Greenfield filters remained in place and intact. Fluoroscopically guided extraction of both wires entrapped by Greenfield filters was successfully performed in the angiography suite.

    Central venous catheters are routinely positioned for hemodynamic monitoring and fluid administration in patients undergoing cardiac surgery, and many well-known complications associated with this manoeuver have been described. Metalic guide wire embolization is a rare complication potentially associated with nonmechanical and mechanical adverse events. The case we report is peculiar as an almost fully endothelialized guide wire was successfully retrieved 9 months after its unintentional embolization in the inferior vena cava.

    In this study, a central venous catheter (CVC)-associated infection model was established in rats to investigate and evaluate the effect of biofilms on the virulence of the pathogens. Twenty-four adult SD rats were randomly divided into biofilm positive (BF+) and biofilm negative (BF-) groups to be challenged with strains of S.epidermidis. Serum levels of inflammatory cytokines were measured and the infection rate and counts of bacteria cells were studied. Compared to rats of BF- group, the serum level of TNF and IL-6 significantly increased in rats of BF+ group (P < 0.01) and the level of IL-10 and IFN-γ significantly decreased (P < 0.01), striking the balance of pro-inflammatory/anti-inflammatory cytokines. The infection rate and bacterial counts in tissues and blood of rats of BF + group were significantly higher than those of rats of BF- group (P < 0.05).Inflammatory cell infiltration in vital organs (heart, lung, liver and kidneys) was more significant in rats of BF+ group than that of rats of BF- group. CVC-associated infection model can be successfully reproduced in rats by injecting 5 × 10(6) CFU of S.epidermidis. Biofilm formation can significantly enhance the virulence of the bacteria, leading to uncontrolled infection. The serum level of inflammatory cytokines, infection rate and the extent of inflammatory cell infiltration are important markers for evaluating the virulence of biofilm.

    Candida albicans is a major agent of fungaemias and frequently causes systemic disease through seeded, blood stream dissemination. These infections, particularly common in hospitalized patients with central venous catheters (CVCs), appear to persevere due to biofilm reservoirs of the yeast that tend to develop on the device. Although it is known that candidal biofilms are intrinsically resistant to antifungals compared with their planktonic counterparts, there is a paucity of data on the expression of antifungal drug resistance genes (DRGs) in candidal biofilms in CVC reservoirs. Furthermore, notwithstanding the fact that CVCs are constantly bathed in human serum, there are no studies on the effect of the latter on the DRG expression in candidal biofilms. Hence, we developed in vitro biofilms of three different C. albicans strains on silicone CVC discs immersed in human serum and evaluated the temporal expression of nine antifungal DRGs. In an attempt to evaluate the effect of hyphal elements on DRG expression, we incorporated a hyphal mutant (HM) and its wild-type (WT) counterpart, as well as a fresh clinical isolate in the studies. Human serum significantly up-regulated DRG transcripts in Candida biofilms on CVCs, at different stages of biofilm growth, while the WT strain over-expressed more DRGs than the HM strain. Here, we report, for the first time, that both human serum and the hyphal elements of the yeast have a profound modulatory effect on DRG expression in C. albicans biofilms on CVCs.

    Cuffed tunneled venous access catheters are commonly used for temporary and permanent access in hemodialysis (HD) patients. These catheters serve an essential role in providing permanent access in subjects in whom all other access options have been exhausted. The predominant complications are catheter thrombosis, catheter fibrin sheating and infection. The aim of this study was to evaluate long-term survival and complications of permanent venous catheters (PVC) placed for the purpose of HD during the period from January 1992 to December 1998, at the Dialysis Units of Lucania (a southern Italian region). A total of 98 PVC were placed in 88 patients during this period. The catheters used were of three types: (a) 72 VasCath Soft Cell catheters (Bard Instrument Company, Toronto, Ont., Canada); (b) 22 PermCath catheters (Quinton Instrument Company, Seattle, Wash., USA), and (c) 4 Tesio catheters (Bellco SpA, Mirandola, Italy). Survival curves of catheters were calculated using the Kaplan-Meier product-limit estimator. The patient survival was 60% at the 78th month. Actually, 52 patients (27 males, 25 females) are still alive: 15 (26.9%) of these patients have diabetes mellitus and 1 has been transplanted. The actuarial survival rate of PVC was 89% in the whole population studied and 82% in subjects alive after 84 months. Twenty-five patients (28.4%) had PVC as the first reliable vascular access. Long-term complications occurred 27 times (1 episode every 44.81 month/patient) as: breakage (3.1%); thrombosis (10.2%); displacement (2.0%); subcutaneous tunnel bleeding (3.1%); inadequate blood flow (7.1%), and infection (10.2%). In conclusion, our data confirm that PVC might represent an effective long-term blood access route for HD. Again, PVC are getting the access of choice for selected patients (i.e., older subjects with cardiovascular diseases and cancer patients) and are enjoying a dramatic increase in use for subjects who are terrified of repetitive venopuncture.

    Different pericardial catheters have been suggested as an effective alternative method for drainage of pericardial effusion. The aim of this study was to determine the performance, pain, and quality of life on use of central venous catheter (CVC) for drainage of pericardial effusion in patients undergoing open heart surgery. Fifty-five patients who had developed pericardial effusion after an open heart surgery (2012–2015) were prospectively assessed. Triple-lumen central catheters were inserted under echocardiographic guidance. Clinical, procedural, complication, and outcome details were analyzed. Intensity of pain and quality of life of patients were assessed using the numerical rating scale and Short-Form Health Survey. CVC was inserted for 36 males and 19 females, all of whom had a mean age of 58.5±15 years, and the mean duration of the open heart surgery was 8±3.5 hours. The mean central venous pressure catheter life span was 14.6 days. No cases of recurrent effusion and complication were reported. The technical success rate of procedure was 100%. Intensity of pain and quality of life of patients had improved during follow-up. CVC insertion is a safe and effective technique for the management of pericardial effusion in patients after open heart surgery. PMID:27826210

    This article reports the results of a study on the effect of alcohol disinfection duration on bacterial load on catheter hubs. Three different levels of disinfection (3, 10, and 15 seconds) were analyzed as well as a positive and negative control. All hubs with the exception of the negative controls were contaminated with a 10 bacterial solution and allowed to dry for 24 hours. Through each hub, 1 mL of sterile saline was flushed; a 10-μL calibrated loop was used to plate the flush onto blood agar. Colony counts were performed on the plates after a 24-hour incubation period. Results revealed that the 3 different levels of disinfection duration were not found to differ significantly in reduction in bacterial load. The duration of disinfection did not significantly change the bacterial load on the hub. However, any disinfection duration significantly decreased the bacterial load as compared to the positive control. A larger study would likely detect a significant result among the disinfections.

    Femoral vein catheterization is an alternative method of obtaining central venous access. Placement of femoral venous catheters (FVCs) is possible in the majority of patients, suitable for most indications, and associated with a low complication rate during insertion. We wished to determine the incidence of infections or other complications resulting when parenteral nutrition was delivered through FVCs. Fifty-two patients were followed from a hospital-wide population including patients in the critical care units. Triple-lumen catheters were placed by using the sterile Seldinger technique, and sites were examined daily for inflammation. Bacteriologic surveillance was accomplished by submitting the catheter tip for semiquantitative cultures. If catheter line sepsis was suspected, blood samples for cultures were drawn through the catheter and peripherally. The rate of occurrence of colonized catheters was 9.6% (five of 52), and catheter sepsis was found in one case (1.9%). Other than inflammation at six (11.5%) of 52 catheter sites, noninfectious complications of FVCs were not found. On the basis of these findings, we consider FVC-delivered parenteral alimentation a safe and effective alternative to other forms of central venous access.

    The supraclavicular approach was first put into clinical practice in 1965 by Yoffa and is an underused method for gaining central access. It offers several advantages over the conventional infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-sided approach offers a straighter path into the subclavian vein. Also, this site is often more accessible during CPR and surgical procedures. In patients who are obese, this anatomic area is less distorted and in patient with congestive heart failure and cervical spine instability repositioning is not required. PMID:23833470

    Objective The use of intravenous in-line filters is effective for the mechanical removal of large particles, precipitates, bacteria, fungi, large lipid globules, and air. However, the routine use of in-line filters remains controversial. Many patients with hematological diseases frequently suffer from bloodstream infections (BSIs) with fatal outcomes. Methods The year before cessation of an in-line filter was defined as the "filter period" and the year after its cessation was defined as the "non-filter period." The number of central line-associated bloodstream infections (CLABSIs), which are defined through surveillance, the catheter utilization rate, the number of patient deaths within 7 days after removal of the central venous catheters (CVCs), and the overall survival rate following CVC insertion were measured. Results During both periods, 84 patients had a total of 140 CVCs with a total number of catheter days of 3,407. There were 10 CVCs with CLABSIs, and the overall CLABSI rate was 2.9/1,000 catheter days, including 4 CVCs with CLABSIs (2.5/1,000 catheter days) during the filter period and 6 CVCs with CLABSIs (3.3/1,000 catheter days) during the non-filter period. The CLABSI rate, catheter utilization rate, and mortality did not differ significantly between the two periods. The only independent variable that was found to be significantly associated with the development of CLABSIs was a neutrophil count of <500×10(6)/L (p<0.05). Conclusion Our study revealed that the cessation of in-line filters from CVCs does not significantly influence the incidence of BSIs and mortality in patients with hematological disease. To confirm our results, however, a large-scale randomized controlled study is warranted.

    Objective: Haematopoietic stem cell recipients need central venous catheters (CVCs) for easy administration of intravenous fluid, medications, apheresis, or dialysis procedures. However, CVCs may lead to infectious or non-infectious complications such as thrombosis. The effect of these complications on transplantation outcome is not clear. This manuscript presents the complication rates of double-lumen tunnelled CVCs and their effect on transplantation outcome. Materials and Methods: Data from 111 consecutive patients, of whom 75 received autologous and 36 received allogeneic peripheral blood stem cell transplantations, were collected retrospectively. The data were validated by the Record Inspection Group of the related JACIE-accredited transplantation centre. Results: Thrombosis developed in 2.7% of recipients (0.9 per 1000 catheter days). Catheter-related infection was identified in 14 (12.6%) patients (3.6 per 1000 catheter days). Coagulase-negative Staphylococcus was the most common causative agent. Engraftment time, rate of 100-day mortality, and development of grade II-IV graft-versus-host disease were not found to be associated with catheter-related complications. Conclusion: These results indicate that adverse events related with tunnelled CVCs are manageable and have no negative effects on transplant outcome. PMID:25805675

    Newborn infants in critical conditions require a permanent intra-venous line to allow for the administration of fluids, parenteral nutrition and drugs. The use of central venous catheters, however, is associated with an increased risk of infections, leading to prolongation of length of stay and higher hospitalization costs, particularly in extremely preterm infants. Dwell time is a significant factor for complications, with a predicted risk of catheter related infections of about 4 per 1000 catheter-days. To reduce the incidence of complications, several requirements must be met, including adequate staff and resources to provide education, training, and quality improvement programs, within a culture of communication and teamwork. Rigorous reporting schedule on line care and the implementation of unique bundle elements, the use of health care failure mode and effect analysis, the judicious use of antibiotics through an antimicrobial stewardship strategy, the application of specific antifungal prophylaxis are among the most effective interventions, while the addition of heparin to parenteral solution, or the use of antibiotic plus heparin lock therapy are under evaluation. Nursing assistance plays a fundamental role in managing central venous lines and in reducing or preventing the incidence of infection, by the application of several complex professional strategies.

    Introduction Totally implantable venous access systems (TIVAS), Swan-Ganz (SG) and central venous catheters (CVC) allow easy and repetitive entry to the central cardiovascular system. Fragments of them may be released inadvertently into the cardiovascular system during their insertion or as a result of mechanical complications encountered during long-term utilization. Aim To present results of percutaneous retrieval of embolized fragments of central venous devices or knotted SG and review the procedural aspects with a series of detailed angiographies. Material and methods Between January 2003 and December 2012 there were 14 (~0.025%) successful retrievals in 13 patients (44 ±16 years, 15% females) of embolized fragments of TIVAS (n = 10) or CVC (n = 1) or of dislodged guide-wires (n = 2) or knotted SG (n = 1). Results Foreign bodies with the forward end located in the right ventricle (RV), as well as those found in the pulmonary artery (PA), often required repositioning with a pigtail catheter as compared to those catheter fragments which were located in the right atrium (RA) and/or great vein and possessed an accessible free end allowing their direct ensnarement with the loop snare (57.0% (4/7) vs. 66.7% (2/3) vs. 0.0% (0/3); p = 0.074 respectively). Procedure duration was 2–3 times longer among catheters retrieved from the PA than among those with the forward edge located in the RV or RA (30 (18–68) vs. 13.5 (11–37) vs. 8 min (8–13); p = 0.054 respectively). The SG catheter knotted in the vena cava superior (VCS) was encircled with the loop snare introduced transfemorally, subsequently cut at its skin entrance and then pulled down inside the 14 Fr vascular sheath. Conclusions By using the pigtail catheter and the loop snare, it is feasible to retrieve centrally embolized fragments or knotted central venous access devices. PMID:27279874

    Objective In 2001 a randomized trial showed decreased mortality with early, goal-directed therapy in septic shock, a strategy later recommended by the Surviving Sepsis Campaign. Placement of a central venous catheter (CVC) is necessary to administer goal-directed therapy. We sought to evaluate nationwide trends in: 1) CVC utilization and 2) the association between early CVC insertion and mortality in patients with septic shock. Design We retrospectively analyzed the proportion of septic shock cases receiving an early (day of admission) CVC and the odds of hospital mortality associated with receiving early CVC from years 1998-2001 compared with 2002-2009. Setting Non-federal acute care hospitalizations from the Nationwide Inpatient Sample, 1998-2009. Interventions None Patients 203,481 (population estimate: 999,545) cases admitted through an emergency department with principal diagnosis of septicemia and secondary diagnosis of shock. Measurements and Main Results From 1998-2009 population-adjusted rates of septic shock increased from 12.6 cases per 100,000 US adults to 78 cases per 100,000. During this time age-adjusted hospital mortality associated with septic shock declined from 40.4% to 31.4%. Early CVC insertion increased from 5.7% (95% CI 5.1-6.3%) to 19.2% (95% CI 18.7-19.5%) cases with septic shock, with an increased rate of early CVC placement identified after 2007. The rate of decline in age-adjusted hospital mortality was significantly greater for patients who received an early CVC (-4.2% per year, 95% CI -3.2, -4.2%) as compared with no CVC (-2.9% per year, 95% CI -2.3, -3.5%), p=0.016. Hospital mortality associated with early CVC insertion significantly decreased from a multivariable-adjusted odds ratio of 1.29 (95% CI 1.14-1.45) prior to 2001 to an adjusted odds ratio of 0.87 (95% CI 0.84-0.90) after 2001. Conclusions Placement of a CVC early in septic shock has increased 3-fold since 1998. The mortality associated with early CVC insertion decreased

    Immuno-compromised patients are at high risk for all kind of infections. Unfortunately, they need central venous catheters (CVCs), which are associated with infectious complications. In this study we examined the effectiveness of chlorhexidine-silver sulfadiazine impregnated CVCs to prevent catheter-related infections in patients receiving high-dose chemotherapy followed by peripheral stem cell transplantation. This historical cohort study evaluated 139 patients of whom 70 patients were provided with non-impregnated CVCs and 69 patients with impregnated CVCs. Patients were treated for different diagnoses. The median number of days a CVC stayed in situ was 18 in the non-impregnated group and 16 in the impregnated group. The median duration of neutropenia of patients with non-impregnated CVCs was 9 days compared with 7 days of patients with impregnated CVCs. We found less catheter colonization (CC) in patients with chlorhexidine-silver sulfadiazine CVCs (RR 0.63, 95% CI 0.41-0.96; P = 0.03). Catheter-related blood stream infections (CR-BSI) were also diminished, but this result was not statistically significant (RR 0.15, 95% CI 0.02-1.15; P = 0.06). The reduction in CC and CR-BSI did not diminish the incidence of fever. We conclude that the use of chlorhexidine-silver sulfadiazine impregnated CVCs provide an important improvement in the attempt to reduce CC and CR-BSI.

    Catheter-related sepsis is a serious and common complication in patients receiving home parenteral nutrition (HPN). Prevention measures, prevalence of infections, types of agents and implanted central venous catheters (CVC), effectiveness of antibiotic therapy have been evaluated in 221 patients consecutively followed in our unit from January 1995 to December 2000. The clinical diagnosis of catheter-related infection was made using well-defined criteria. Patients were divided into two groups: A and B, receiving instructions with different modalities: standard (A) and detailed (B), respectively. Sixty CVC-related sepsis occurred in 32 (14%) patients. A multivariate analysis showed that the duration of HPN (P<0.001; OR=0.9), type of catheter (P=0.009; OR=0.12) and type of disease (P=0.033; OR=4.92) significantly influence catheter infection. The type of implanted CVC (159 port-a-cath in 153 patients and 71 tunnelled in 68) seems to affect the infection rate, this being lower in tunnelled (P=0.03). Infection rate was lower in B vs A group (P<0.001) with all types of catheters, suggesting the preventive role of very careful training. In particular, the incidence of CVC-related sepsis was 6/1000 days of HPN (i.e. 6/1000 days of catheterization) in Group A and 3/1000 in Group B. Systemic and antibiotic lock therapy was performed with an 83% successful rate. Gram-positive bacteria were the most frequent CVC infection agents, which are usually eradicated by antibiotic therapy lasting 7 days.

    The efficacy of 1% chlorhexidine-gluconate ethanol and 10% povidone-iodine for skin antisepsis of central venous catheter (CVC) sites were compared among hematology patients. The CVC site colonization rates of those groups were 11.9% and 29.2%, respectively, and the catheter-associated blood stream infections were 0.75 and 3.62 per 1,000 catheter-days, respectively. One percent chlorhexidine-gluconate ethanol was superior to povidone-iodine to reduce skin colonizers at CVC sites even when catheters were used for long duration.

    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. PMID:27512162

    Central venous catheterization is a frequently performed procedure in internal medicine units. Residents in training frequently share the same questions, doubts and fears about this procedure : "Should I perform a subclavian catheterization in a patient with mild thrombopenia?"; "Which site has the lesser complication rate?"; "After how long does a catheter need to be replaced?". This mini-review of the current literature tries to answer this and other questions.

    Superior vena cava syndrome results from obstruction of flow through the vessel either by external compression or thrombosis. External compression by intrathoracic neoplasms is the most common etiology. Thrombosis of the vessel most often occurs in the setting of indwelling catheters or pacemakers. The diagnosis is suggested by the clinical manifestations of facial and upper extremity swelling, dyspnea, and cough. It is confirmed by CT scan showing the development of collateral flow around the lesion. In this report, we present a patient who developed superior vena cava thrombosis after undergoing a short period of central venous catheterization and a Whipple procedure for adenocarcinoma of the ampulla of Vater. The endothelial damage caused by the catheter, the low-flow state induced by the large fluid shifts during the operation, and the hypercoagulable state induced by malignancy fulfill Virchow's triad for venous thrombosis. To our knowledge, this is the first reported case of superior vena cava syndrome after the Whipple procedure with symptoms appearing after a shorter period of catheterization than previously reported in the adult literature.

A 22-year-old colombian-woman, student, without toxic habits was admitted because of temporary left astrocytoma (grade II). Nine days after implementing a catheter in the right subclavian vein she presented high fever (39.5 degrees C), shivers, progressive right side neck swelling and odinofagia. She had leukocytosis (26,300 cells/microl) and normal cerebrospinal fluid. After withdrawing the catheter, Staphylococcus aureus was isolated in the tip of the catheter and in four bottles of blood cultures. A neck CT demonstrated expansion and absence of contrast in the right internal jugular vein. The patient evolved satisfactorily with cloxacillin, gentamycin and low molecular weight heparin.

    Bacterial infections of central venous catheters (CVCs) cause much morbidity and mortality, and are usually diagnosed by concordant culture of blood and catheter tip. However, studies suggest that culture often fails to detect biofilm bacteria. This study optimizes X-ray micro-focus computed tomography (X-ray µCT) for the quantification and determination of distribution and heterogeneity of biofilms in in vitro CVC model systems. Bacterial culture and scanning electron microscopy (SEM) were used to detect Staphylococcus epidermidis ATCC 35984 biofilms grown on catheters in vitro in both flow and static biofilm models. Alongside this, X-ray µCT techniques were developed in order to detect biofilms inside CVCs. Various contrast agent stains were evaluated using energy-dispersive X-ray spectroscopy (EDS) to further optimize these methods. Catheter material and biofilm were segmented using a semi-automated matlab script and quantified using the Avizo Fire software package. X-ray µCT was capable of distinguishing between the degree of biofilm formation across different segments of a CVC flow model. EDS screening of single- and dual-compound contrast stains identified 10 nm gold and silver nitrate as the optimum contrast agent for X-ray µCT. This optimized method was then demonstrated to be capable of quantifying biofilms in an in vitro static biofilm formation model, with a strong correlation between biofilm detection via SEM and culture. X-ray µCT has good potential as a direct, non-invasive, non-destructive technology to image biofilms in CVCs, as well as other in vivo medical components in which biofilms accumulate in concealed areas.

    We describe a very rare case of an indwelling central venous catheter (CVC) through the left internal jugular vein that perforated the superior vena cava (SVC) wall postoperatively, although the CVC was placed in the appropriate position preoperatively. Three days after CVC insertion, a chest radiograph showed that the CVC tip had moved from the lower SVC to the upper SVC. Five days after the insertion, computed tomography showed SVC perforation and the resulting hydrothorax. In cases of CVC insertion through the left side, the CVC tip should not be placed in the upper SVC (zone B). Considering individual clinical factors and the indwelling period for the CVC, the left innominate vein (zone C) may be a suitable site for the left-sided CVC tip to reduce the risk of SVC perforation.

    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 (p<0.001) and to have a higher frequency of diabetes mellitus (p = 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 (p<0.001) and hospital admissions (p<0.001). At the end of follow-up, HD-TCC patients had a higher rate of dialysis access-related complications (1.53 vs. 0.93 vs. 0.64, per patient-year; p<0.001) and hospitalizations (0.47 vs. 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 (p<0.001). In multivariate analysis, HD-TCC use at the time of dialysis initiation was the important factor associated with death (HR 16.128, 95%CI [1.431-181.778], p = 0.024). Conclusion Our results suggest that HD

    This article deals with the use of 56 silastic-catheters in the intensive care of premature and new-born with mean weights of 1550 g according to the Shaw-method. The clinical use with regard to early and late complications was studied by means of scanning electron microscopy of 11 catheters. The results were compared with the complications associated with PVC-catheters. The silastic-catheters has the following advantages: over a longer period it does not lose its mechanical properties, it is athrombogenic and has only few complications regarding infection and thrombosis. Local reactions cannot, however be eliminated. We can extend the use of silastic-catheters by giving blood, drugs and by taking blood samples, by this way intensive care of the new-born is less stressful.

    The aim of this study was to predict the probability of central venous catheter-related bloodstream infections (CRBSIs) in patients with haematologic malignancies using a modified version of the Infection Probability Score (mIPS). In order to perform a prospective, mono-centric surveillance of complications in clinical routine due to short-term central venous catheters (CVCs) in consecutive patients receiving chemotherapy from March 2013 to September 2014, IPS was calculated at CVC insertion and removal (mIPSin and mIPSex, respectively). We used the 2012 Infectious Diseases Working Party of the German Society of Haematology and Medical Oncology (AGIHO/DGHO) criteria to define CRBSI. In total, 143 patients (mean 59.5 years, 61.4 % male) with 267 triple-lumen CVCs (4044 CVC days; mean 15.1 days, range 1-60 days) were analysed. CVCs were inserted for therapy of acute leukaemia (53.2 %), multiple myeloma (24.3 %) or lymphoma (11.2 %), and 93.6 % were inserted in the jugular vein. A total of 66 CRBSI cases (24.7 %) were documented (12 definite/13 probable/41 possible). The incidence was 16.3/1000 CVC days (2.9/3.1/10.1 per 1000 CVC days for definite/probable/possible CRBSI, respectively). In CRBSI cases, the mIPSex was higher as compared to cases without CRBSI (13.1 vs. 7.1; p < 0.001). The best mIPSex cutoff for CRBSI prediction was 8 points (area under the curve (AUC) = 0.77; sensitivity = 84.9 %, specificity = 60.7 %, negative predictive value = 92.4 %). For patients with an mIPSex ≥8, the risk for a CRBSI was high (odds ratio [OR] = 5.9; p < 0.001) and even increased if, additionally, CVC had been in use for about 10 days (OR = 9.8; p < 0.001). In case other causes of infection are excluded, a mIPSex ≥8 and duration of CVC use of about 10 days predict a very high risk of CRBSI. Patients with a mIPSex <8 have a low risk of CRBSI of 8 %.

    Three patients were referred for lung ventiliation and perfusion (V/Q) imaging with symptoms strongly suggestive of pulmonary embolus (PE). Chest roentgenograms and xenon ventilation studies on all three were normal, save for prominent mediastinal silhouettes and effusions. Technetium-99m macroaggregated albumin(Tc-99m MAA), when injected through the central venous catheter (CVP), revealed mediastinal localization, whereas antecubital injections showed normal pulmonary perfusion. Contrast fluoroscopy introduced through the venous catheter in the first patient defined the extravasation. For patients under strong suspicion of PE, with a venous catheter whose distal tip is seen about the level of the heart on chest radiograph, the authors recommend administering the perfusion agent slowly through the central catheter to exclude catheter-induced complications. When extravasation is detected, injection of Tc-99m MAA by peripheral vein should be used to exclude PE.

    Staphylococcus aureus is frequently isolated in the setting of infections of indwelling medical devices, which are mediated by the microbe's ability to form biofilms on a variety of surfaces. Biofilm-embedded bacteria are more resistant to antimicrobial agents than their planktonic counterparts and often cause chronic infections and sepsis, particularly in patients with prolonged hospitalizations. In this study, we demonstrate that sustained nitric oxide-releasing nanoparticles (NO-np) interfere with S. aureus adhesion and prevent biofilm formation on a rat central venous catheter (CVC) model of infection. Confocal and scanning electron microscopy showed that NO-np-treated staphylococcal biofilms displayed considerably reduced thicknesses and bacterial numbers compared to those of control biofilms in vitro and in vivo, respectively. Although both phenotypes, planktonic and biofilm-associated staphylococci, of multiple clinical strains were susceptible to NO-np, bacteria within biofilms were more resistant to killing than their planktonic counterparts. Furthermore, chitosan, a biopolymer found in the exoskeleton of crustaceans and structurally integrated into the nanoparticles, seems to add considerable antimicrobial activity to the technology. Our findings suggest promising development and translational potential of NO-np for use as a prophylactic or therapeutic against bacterial biofilms on CVCs and other medical devices.

    Purpose Evaluation of the efficacy of single-shot, low-dose urokinase administration for the treatment of port catheter-associated fibrin sheaths. Methods Forty-six patients were retrospectively evaluated for 54 episodes of port catheter dysfunction. The presence of a fibrin sheath was detected by angiographic contrast examinations. On an outpatient basis, patients subsequently received thrombolysis consisting of a single injection of urokinase (15.000 IU in 1.5 mL normal saline) through the port system. A second attempt was made in cases of treatment failure. Patients were followed up for technical success, complications and long-term outcome. Results Port dysfunction occurred at a median of 117 days after implantation (range: 7–825 days). The technical success after first port dysfunction by thrombolysis was 87% (40/46); thereof, initial thrombolysis was effective in 78% (36/46). Nine patients (20%) received a second dose of urokinase after previous treatment failure. Follow-up was available for 26 of 40 patients after successful thrombolysis. In 8 of these, rethrombosis occurred after a median of 98 days (range: 21–354 days), whereby rethrombolysis was effective in 5 of 7 (63%) patients. The overall success of all thrombolyses performed was 70% (45/64). No procedure-related technical or clinical complications occurred. After first favorable thrombolysis, a Kaplan–Meier analysis yielded a 30-, 90- and 180-day probability of patency of 96%, 87% and 81%. Conclusion Thrombolytic therapy on an outpatient basis appears to be a safe and efficient. Three-month patency rates are comparable to more invasive treatment options, including catheter exchange over a guide wire and percutaneous fibrin sheath stripping. PMID:28182117

    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.

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.

    Central venous catheterization is a very common technique, although its complications can be multiple and sometimes fatal. A case is presented of cardiac tamponade by parenteral nutrition a few hours after moving a central venous catheter peripherally inserted a few days before. The diagnosis was made by echocardiography, and an emergency pericardiocentesis was performed, achieving complete recovery of the patient. Peripherally inserted central venous catheters are more likely to change their position secondary to the movements of the patient's arm, thus it is important to use soft catheters, make sure the tip lies above the carina to avoid perforation of the pericardial reflexion, and fix it well to the skin. Diagnosis must be made as soon as possible, given the high mortality rate of this complication, and the essential diagnostic tool is echocardiography. Elective treatment consists of early catheter withdrawal and emergency pericardiocentesis.

    Central venous cannulation is a commonly performed procedure which facilitates resuscitation, nutritional support, and long-term vascular access. Mechanical complications most often occur during insertion and are intimately related to the anatomic relationship of the central veins. Working knowledge of surface and deep anatomy minimizes complications. Use of surface anatomic landmarks to orient the deep course of cannulating needle tracts appropriately comprises the crux of complication avoidance. The authors describe use of surface landmarks to facilitate safe placement of internal jugular, subclavian, and femoral venous catheters. The role of real-time sonography as a safety-enhancing adjunct is reviewed. PMID:22312225

    The aim of the present study was to characterize clinical isolates of Staphylococcus epidermidis, one of the bacterial species most often implicated in foreign-body-associated infections, for their ability to form biofilms and for the presence of mecA and IS256 element. Sixty-seven Staphylococcus epidermidis clinical isolates, obtained from implantable medical devices, were investigated. Overall, 70% of the strains were positive for ica operon genes, 85% possessed atlE, and 46% contained aap. In 89% of the population, the Congo red agar test confirmed the correlation between the presence of ica genes and slime expression. Almost all of the strains could be classified as biofilm producers by both the crystal violet assay and microscopy. The bacterial population studied showed a very high frequency of strains positive for mecA as well as for the IS256 element. Although well-structured biofilms have been previously observed only in those strains possessing genes belonging to the ica operon, this study demonstrates that strains lacking specific biofilm-formation determinants can be isolated from catheters and can form a biofilm in vitro. Hence, different and yet-to-be identified factors may work together in the formation and organization of complex staphylococcal microbial communities and sustain infections associated with implanted medical devices.

    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

    Central venous catheters (CVCs) are widely used for therapeutic purposes and to measure hemodynamic variables that cannot be recorded from a peripheral vein. However, the method can involve complications. In cardiac surgery, CVCs are electively placed in the right internal jugular vein but there is little information on deep venous thrombosis (DVT) in catheterized veins (CVC-related DVT) or on secondary pulmonary embolism (PE). The impact of CVC-related DVT and PE in cardiac surgery and measures to prevent PE were assessed. We used ultrasonography (US) to check the point of insertion of CVC in 815 patients in the intensive cardiac rehabilitation unit after heart surgery. In this series, 386 patients (48%) had CVC-related DVT; those already receiving anticoagulant, and considered at low risk, continued that therapy, while those taking an antiplatelet agent (aspirin 100 mg daily) but deemed at high risk of PE from the US findings were given an anticoagulant instead. Only patients with CVC-related DVT at low risk of PE continued taking aspirin. At 3 months, there were no cases of PE among patients receiving an anticoagulant, but six on antiplatelet had non-fatal PE. The prevalence of PE in the whole series of 815 patients was 0.7%. CVC-related DVT is a frequent complication of heart surgery. Anticoagulant therapy started early does not prevent thrombus formation but probably prevents PE, whereas antiplatelet gives no such protection. Sonographic screening of the CVC removal in intensive care unit may be useful for avoiding PE after CVC-related DVT.

    This report presents our experience using double-lumen, silicone rubber, indwelling central venous catheters with a subcutaneous Dacron cuff as access for hemodialysis. Twenty-seven catheters were placed in 27 patients through venous cutdowns. A 10-cm subcutaneous tunnel was created leaving the Dacron cuff 2 cm from the external exit. Sixteen Raaf catheters (lumen diameter [LD], 1 mm), three double-lumen Hickman catheters (LD, 1.6 mm) and eight HemoCath catheters (LD, 2 mm) were used. The tip of the catheter was positioned fluoroscopically in either the superior vena cava or the right atrium. One hundred fifty-nine treatments were done with the Raaf catheters (mean blood flow [MBF], 188.1 +/- 26.4 mL/min); two of these catheters became obstructed and could not be used further. Three double-lumen Hickman catheters were used in 12 hemodialysis treatments (MBF, 216.3 +/- 27.1 mL/min). One hundred fifty-five treatments were done using the HemoCath catheters (MBF, 236.7 +/- 5.5 mL/min). The degree of recirculation of these catheters was 8.56% +/- 4.34%. The major advantages of this modality include simplicity of introduction, lack of serious complications, no sacrifice of major arteries, no need for venipuncture, and potential use in either short- or long-term hemodialysis.

    Catheter fracture represents a rare problem among non-infectious complications following the insertion of totally implantable long-term central venous access systems for the application of chemotherapeutic agents. A literature survey revealed a total incidence of catheter fractures of 0-2.1%. Imminent catheter fracture can be identified radiologically, using different degrees of catheter narrowing between the clavicle and the first rib, called pinch-off sign. Two cases of catheter fracture are described and potential causes are discussed. Recommendations to avoid the pinch-off sign with the subsequent risk of catheter fracture and migration include a more lateral and direct puncture of the subclavian vein. In case of catheter narrowing in the clavicular-first rib angle, patients should be followed carefully by chest X-rays every 4 weeks. Whenever possible, the system should be removed within 6 months following insertion.

    Peripheral vein catheterization is generally considered a harmless procedure. Venous catheter rupture associated with pulmonary embolism is an unlikely but potentially serious complication. We report a case of a peripheral venous catheter (PVC) fracture with pulmonary artery embolization in the left lower lobe treated successfully by a surgical approach. The positioning of a PVC is not always a harmless procedure. Every time there are difficulties in positioning or in removal of a catheter device, it should be carefully inspected to verify integrity. The advisability of removal of these small foreign bodies is debated; percutaneous retrieval is preferred, while surgery should be discussed case by case. PMID:28149586

    Pediatric patients undergoing surgery for spinal deformity may benefit from central venous access to provide intraoperative monitoring and fluid resuscitation. For pediatric surgical patients requiring central access, we hypothesized that placing a peripherally inserted central catheter (PICC) line preoperatively should decrease time from induction of anesthesia to incision and result in improved patient safety and decreased operating room charges. This was a retrospective, nonrandomized, and case comparison study. Clinical records of all children with adolescent idiopathic scoliosis or neuromuscular scoliosis treated surgically by the senior author between December 2007 and April 2012 were reviewed. Control group patients had a central venous catheter (CVC) placed by the anesthesiologist after induction of anesthesia. The trial group had a PICC placed under local anesthesia the day before surgery by an experienced vascular access team. The time from induction of anesthesia to the time for the surgical incision was determined for each study group. The CVC line placement charges were determined by the operating room time charges at $214/min. Charges saved were the mean time difference multiplied by the operating room time charge, less the charge for PICC line insertion ($1282). There were 29 neuromuscular patients, the mean age was 13 years (SD: 4 years). The mean time from induction to incision for the PICC group was 91 min [95% confidence interval (CI): 67-115 min] and for the CVC group 113 min (95% CI: 99-127 min, P=0.083). For this mean time difference of 22 min, the estimated cost savings would be $3426 per patient. There were 59 patients with adolescent idiopathic scoliosis, the mean age was 14 years (SD: 2 years). The mean time from induction to incision for the PICC group was 78 min (95% CI: 74-82 min) and for the CVC group 106 min (95% CI: 96-116  min, P≤0.001). For this mean time difference of 28 min, the estimated cost savings would

    An unusual central venous catheter (CVC)-related infection caused by Candida membranaefaciens in a patient with non-Hodgkin's lymphoma is described. Clinical signs and microbiological results observed in this case may support the hypothesis of an emerging CVC-related fungaemia, because of new azole-resistant yeast, successfully treated with liposomal amphotericin B. To date C. membranaefaciens (the teleomorph of Pichia membranaefaciens) has traditionally been considered non-pathogenic and this report seems to be the first case of systemic fungal infection. We believe that another fungus can be added to the list of opportunistic strains.

    We report our decennial experience with 1161 newly-placed long-term central venous catheters inserted in 919 hematology-oncology patients for a total of 413,901 CVC-days of observation. Most of the CVCs were partially-implanted, open-ended, Broviac-Hickman type of CVC (95 %). One thousand and twenty-four complications were recorded equal to 2.47 per 1000 CVC-days. The frequency of complications per CVC, the rate of episodes per 1000 CVC-days, and removal rate were malfunction/occlusion 42 %, 1.18/1000, and 2.3 %; mechanical (dislodgement/rupture/kinking) 18.3 %, 0.51/1000, and 77.4 %; bacteremia 14.8 %, 0.42/1000, and 18.6 %; exit-site/tunnel infection 11.5 %, 0.32/1000, and 9.7 %; thrombosis 0.86 %, 0.02/1000, and 30 %; pneumothorax 0.52 %, 0.01/1000, and 0. In multivariate analysis, the risk factors were for mechanical complications, a younger age <6.1 years at CVC insertion (HR 1.8, p = 0.0006); for bacteremia, a double lumen CVC (HR 3.1, p < 0.0001) and the surgical modality of CVC insertion (HR 1.5, p = 0.03); for exit-site/tunnel infection, a double lumen CVC (HR 2.1, p = 0.0003) and a diagnosis of leukemia or lymphoma (HR 1.8, p = 0.01); for malfunction/occlusion, an age <6.1 years (HR 1.6, p = 0.0003), the diagnosis of leukemia or lymphoma (HR 1.9, p < 0.0001) and double lumen CVC (HR 1.33, p = 0.023). The cumulative incidence of premature CVC removal was 29.2 % and the risk factors associated with this event were the surgical modality of CVC insertion (HR 1.4, p = 0.0153) and an age at CVC positioning less than 6.1 years (HR 1.6, p = 0.0025). We conclude that a best-practice set of rules resulted in reduced CVC complications.

    Background Bloodstream infections from central venous catheters (CVC-BSIs) increase morbidity and costs in intensive care units (ICUs). Substantial reductions in CVC-BSI rates have been reported using a combination of technical and non-technical interventions. Methods We conducted a 2-year, four-cluster, stepped non-randomised study of technical and non-technical (behavioural) interventions to prevent CVC-BSIs in adult and paediatric ICUs in England. Random-effects Poisson regression modelling was used to compare infection rates. A sample of ICUs participated in data verification. Results Of 223 ICUs in England, 215 (196 adult, 19 paediatric) submitted data on 2479 of 2787 possible months and 147 (66%) provided complete data. The exposure rate was 438 887 (404 252 adult and 34 635 paediatric) CVC-patient days. Over 20 months, 1092 CVC-BSIs were reported. Of these, 884 (81%) were ICU acquired. For adult ICUs, the mean CVC-BSI rate decreased over 20 months from 3.7 in the first cluster to 1.48 CVC-BSIs/1000 CVC-patient days (p<0.0001) for all clusters combined, and for paediatric ICUs from 5.65 to 2.89 (p=0.625). The trend for infection rate reduction did not accelerate following interventions training. CVC utilisation rates remained stable. Pre-ICU infections declined in parallel with ICU-acquired infections. Criterion-referenced case note review showed high agreement between adjudicators (κ 0.706) but wide variation in blood culture sampling rates and CVC utilisation. Generic infection control practices varied widely. Conclusions The marked reduction in CVC-BSI rates in English ICUs found in this study is likely part of a wider secular trend for a system-wide improvement in healthcare-associated infections. Opportunities exist for greater harmonisation of infection control practices. Future studies should investigate causal mechanisms and contextual factors influencing the impact of interventions directed at improving patient care. PMID:22996571

    The placement of central catheters through the subclavian and jugular venous path can be complicated by the cannulation of an artery or an aberrant venous path. The most frequent anomaly of the embryological development of the caval vein is the persistence of the left superior vena cava (LSVC). The implantation of catheters in the LSVC can be suspected by its anomalous route in thorax radiography. Gasometry and the pressure curve of the vessel make it possible to rule out an arterial catheterisation. Diagnostic confirmation is obtained through angiography, echocardiography, computerised tomography or cardiac resonance. The doctor who regularly implants central venous catheters must be familiar with the anatomy of the venous system and its variants and anomalies, since their presence might influence the handling of the patient.

    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.

  18. Risk of infection due to medical interventions via central venous catheters or implantable venous access port systems at the middle port of a three-way cock: luer lock cap vs. luer access split septum system (Q-Syte)

    Background Many cancer patients receive a central venous catheter or port system prior to therapy to assure correct drug administration. Even appropriate hygienic intervention maintenance carries the risk of contaminating the middle port (C-port) of a three-way cock (TWC), a risk that increases with the number of medical interventions. Because of the complexity of the cleaning procedure with disconnection and reconnection of the standard luer lock cap (referred as “intervention”), we compared luer lock caps with a “closed access system” consisting of a luer access split septum system with regard to process optimization (work simplification, process time), efficiency (costs) and hygiene (patient safety). Methods For determination of process optimization the workflow of an intervention according to the usual practice and risks was depicted in a process diagram. For determining the actual process costs, we analyzed use of material and time parameters per intervention and used the process parameters for programming the process into a simulation run (n = 1000) to determine the process costs as well as their differences (ACTUAL vs. NOMINAL) within the framework of a discrete event simulation. Additionally cultures were carried out at the TWC C-ports to evaluate possible contamination. Results With the closed access system, the mean working time of 5.5 minutes could be reduced to 2.97 minutes. The results for average process costs (labour and material costs per use) were 3.92 € for luer lock caps and 2.55 € for the closed access system. The hypothesis test (2-sample t-test, CI 0.95, p-value<0.05) confirmed the significance of the result. In 50 reviewed samples (TWC’s), the contamination rate for the luer lock cap was 8% (4 out of 50 samples were positive), the contamination rate of the 50 samples with the closed access system was 0%. Possible hygienic risks (related to material, surroundings, staff handling) could be reduced by 65.38%. Conclusions In the

    Background Outside ICUs, CVC-ABSIs epidemiology and the results of strategies for their prevention are not well known. The aim of this study was to investigate the epidemiology and the impact of a multifaceted “bundle” approach in controlling CVC-ABSIs outside ICU. Methods From 1991 we performed prevalence studies of device and parenteral nutrition use, and prospective surveillance of all episodes of CVC-ABSIs in a 350-bed teaching hospital. CVC-ABSIs incidence/1,000 inpatient-days was calculated. An estimated CVC-ABSIs incidence/1,000 catheter-days was calculated based on the prevalence rates of catheter use and the total number of inpatient-days in each year. On november 2008, an education programme was instituted for care of catheter lines: reinforcing instructions in aseptic insertion technique, after care and hand-washing; in order to assess the adherence to these measures the quantity of alcohol-based hand-rub consumption/1,000 patient-days was quoted in litres. From January 2009, a checklist intervention for CVC insertion in ICU was started: hand hygiene, using full barrier precautions, cleaning the skin with alcoholic chlorhexidine, avoiding femoral access and removing unnecessary catheters. Compliance with the central line insertion checklist was measured by real-time audits and was achieved in 80% of cases. Results Prevalence of use of CVC and parenteral nutrition was similar throughout the study. We followed-up 309 CVC-ABSIs cases. Estimated CVC-ABSIs rate progressively increased to 15.1/1,000 catheter-days in 2008 (0.36/1,000 inpatient-days). After the intervention, the alcohol-based hand-rub consumption increased slightly and estimated CVC-ABSIs rate fell to 10.1 /1,000 catheter-days in last three years (0.19/1,000 inpatient-days), showing a 32.9% decrease. The infection rates achieved were lower in Internal Medicine wards: decreased from 14.1/1,000 catheter-days (0.17/patient-days) in 2008 to 5.2/1,000 catheter-days (0.05/1,000 inpatient-days) in

    Intravenous prostacyclins are a valuable treatment for patients with severe pulmonary arterial hypertension, leading to improved exercise capacity, haemodynamics, quality of life and survival. Unfortunately, due to the short half-life of these drugs, they need to be administered continuously through central venous catheters. Despite aseptic technique, regular dressing changes, tunneled central venous catheters and patient education, patients are exposed to central venous catheter associated infections. These infections cause significant morbidity and mortality. The clinical presentation, microbiology, consequences and management of these central venous catheter associated infections in pulmonary arterial hypertension patients treated with intravenous prostacyclins are discussed.

    Serious analytic errors in potassium measurements have been identified in blood specimens obtained from newly inserted central catheters. Erroneous elevated readings have been related to interactions of chemistry analyzer electrodes and substances fixed to external and intraluminal walls of the central catheter. Anecdotal summaries of this phenomenon are presented to enable the nurse to recognize potential problems when sampling blood from central catheters. Studies were performed to determine the amount of flush necessary to clear the catheter of interfering residue. To eliminate this potentially hazardous occurrence, recommended flush volumes, nursing implications, and actions are described.

    Introduction The lack of suitable veins in children with critical central venous access requirements is a major obstacle to optimal care and is potentially life-threatening. We present outcomes following the use of vein-preserving (VP) surgical techniques, notably the sheath exchange for tunneled lines (SETL). Materials and Methods A retrospective, single observer analysis of a prospectively maintained departmental logbook as well as the medical records of patients. Two broad groups of central line replacements were identified; those inserted following removal of a previous line and a traditional "plastic-free" (PF) period and those exchanged without such an interval. Results Overall, 19 lines were directly exchanged during the study period and compared with 34 inserted after a PF period. Similar catheter life spans and infection rates were demonstrated in each group; 125 (range, 78-173) days in VP exchanges versus 122 (range, 70-175) days in PF replacements (p = 0.41). Line Sepsis resulting in removal or change of line occurred at 103 (range, 60-147) days in VP group versus 104 (range, 45-164) days in PF (p = 0.73). Conclusion For children with critical venous access requirements, direct line exchange procedures are a robust and reproducible means of vein preservation. The outcomes compare favorably with those following the more traditional removal, a PF period and reinsertion.

    Despite the high number of central venous access devices inserted annually, there are limited data on the incidence of the associated procedural complications, many of which carry substantial clinical risk. This point was highlighted in the recently published Association of Anaesthetists of Great Britain and Ireland 'Safe vascular access 2016' guidelines. This trainee-led snapshot study aimed to identify the number of central venous catheter insertions and the incidence of serious complications across multiple hospital sites within a fixed two-week period. Secondary aims were to identify the availability of resources and infrastructure to facilitate safe central venous catheter insertion and management of potential complications. Fifteen hospital sites participated, completing an initial resource survey and daily identification of all adult central venous catheter insertions, with subsequent review of any complications detected. A total of 487 central venous catheter insertions were identified, of which 15 (3.1%) were associated with a significant procedural complication. The most common complication was failure of insertion, which occurred in seven (1.4%) cases. Facilities to enable safer central venous catheter insertion and manage complications varied widely between hospitals, with little evidence of standardisation of guidelines or protocols.

    Percutaneous central venous catheter access is common-place in surgical patients. Though several major complications of this procedure have been described, pneumothorax is the most common. Pneumothorax is routinely assessed by a chest X-ray within 2 hours after catheter placement. During a recent 6-month interval, the authors identified five patients with delayed onset and diagnosis of pneumothorax following percutaneous central venous access. All immediate post-insertion chest X-rays were normal; however, subsequent chest X-ray showed evidence of pneumothoraxes. The pneumothorax contributed to the death of one patient on positive pressure ventilation. A review of the literature revealed a total of 18 patients in the English literature with this complication. Although the incidence of delayed pneumothorax is low, it is, in some instances, life threatening, particularly in patients on positive pressure ventilation. A high index of suspicion is required to diagnosis and treat this reversible condition.

    The aim of this study was to compare incidence rates of mechanical and infectious complications associated with central venous catheterization via the internal jugular vein (IJV) versus the subclavian vein (SV) among 45 consecutive patients undergoing orthotopic liver transplantation (OLT) between January 2000 and June 2004. The subjects were divided into two groups according to the site of central venous catheterization (IJV or SV). We recorded each patient's physical characteristics, international normalized ratio (INR), partial thromboplastin time, platelet levels, number of puncture attempts, success/failure of central venous catheterization, duration of catheter placement, occurrence of catheter tip misplacement, arterial puncture, incidence of hematoma or pneumothorax, catheter-related infection, or bacterial colonization of the catheter. Senior staff anesthesiologists performed 22 SV and 23 IJV catheterizations for the 45 OLT procedures. The SV and IVJ groups both had minor coagulation abnormalities with slightly increased INR values at the time of catheterization. There were no significant differences between the groups with respect to success of central venous catheterization (100% for both), numbers of attempted punctures, duration of catheter placement, and incidence rates of mechanical and infectious complications. Both groups showed high frequencies of catheter tip misplacement, with right atrium as the site of misplacement in all cases. Two patients in the IJV group (8.7%) developed hematomas after accidental carotid artery puncture. The results suggest that, when performed by experienced anesthesiologists, central venous catheterization via the SV is an acceptable alternative to IJV catheterization for patients undergoing OLT.

    Venous access devices are of pivotal importance for an increasing number of critically ill patients in a variety of disease states and in a variety of clinical settings (emergency, intensive care, surgery) and for different purposes (fluids or drugs infusions, parenteral nutrition, antibiotic therapy, hemodynamic monitoring, procedures of dialysis/apheresis). However, healthcare professionals are commonly worried about the possible consequences that may result using a central venous access device (CVAD) (mainly, bloodstream infections and thrombosis), both peripherally inserted central catheters (PICCs) and centrally inserted central catheters (CICCs). This review aims to discuss indications, insertion techniques, and care of PICCs in critically ill patients. PICCs have many advantages over standard CICCs. First of all, their insertion is easy and safe -due to their placement into peripheral veins of the arm- and the advantage of a central location of catheter tip suitable for all osmolarity and pH solutions. Using the ultrasound-guidance for the PICC insertion, the risk of hemothorax and pneumothorax can be avoided, as well as the possibility of primary malposition is very low. PICC placement is also appropriate to avoid post-procedural hemorrhage in patients with an abnormal coagulative state who need a CVAD. Some limits previously ascribed to PICCs (i.e., low flow rates, difficult central venous pressure monitoring, lack of safety for radio-diagnostic procedures, single-lumen) have delayed their start up in the intensive care units as common practice. Though, the recent development of power-injectable PICCs overcomes these technical limitations and PICCs have started to spread in critical care settings. Two important take-home messages may be drawn from this review. First, the incidence of complications varies depending on venous accesses and healthcare professionals should be aware of the different clinical performance as well as of the different risks

    Central venous catheterization is a common procedure for critically ill patients. Like all procedures, it has its complications, one of which is thrombosis. Reports of thrombosis are commoner among cancer patients. We present a 37 year old non cancer patient who developed thrombi in both right and left internal jugular veins, 10 and 13 days respectively after insertion of central venous catheter. This was detected by ultrasound scans of the neck while attempting re-cannulation for parenteral feeding. She also had left lower limb deep venous thrombosis, confirmed by doppler scan, which was managed with low molecular weight heparin and warfarin. The patient was subsequently treated with streptokinase. A repeat scan of the internal jugular veins 4 days after thrombolysis revealed a reduction in size of the thrombi. Symptoms of deep venous thrombosis improved and she was transferred to the wards where she made remarkable improvement. This case illustrates the potential usefulness of ultrasound guided-central line insertion in patients who have had central venous lines inserted previously in order to detect thrombi.

    Formation of resilient biofilms on medical devices colonized by pathogenic microorganisms is a major cause of health-care associated infection. While in vitro biofilm analyses led to promising anti-biofilm approaches, little is known about their translation to in vivo situations and on host contribution to the in vivo dynamics of infections on medical devices. Here we have developed an in vivo model of long-term bacterial biofilm infections in a pediatric totally implantable venous access port (TIVAP) surgically placed in adult rats. Using non-invasive and quantitative bioluminescence, we studied TIVAP contamination by clinically relevant pathogens, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Staphylococcus epidermidis, and we demonstrated that TIVAP bacterial populations display typical biofilm phenotypes. In our study, we showed that immunocompetent rats were able to control the colonization and clear the bloodstream infection except for up to 30% that suffered systemic infection and death whereas none of the immunosuppressed rats survived the infection. Besides, we mimicked some clinically relevant TIVAP associated complications such as port-pocket infection and hematogenous route of colonization. Finally, by assessing an optimized antibiotic lock therapy, we established that our in vivo model enables to assess innovative therapeutic strategies against bacterial biofilm infections.

    Purpose Inhibitory effect of paclitaxel on neointimal hyperplasia after open cutdown has not been elucidated. Methods For the control group (n = 16), silicone 2.7-Fr catheters were placed via the right external jugular vein with the cutdown method. For the treatment group (n = 16), a mixture of 0.65 mg of paclitaxel and 1 mL of fibrin glue was infiltrated around the exposed vein after cutdown. After scheduled intervals (1, 2, 4, and 8 weeks), the vein segment was harvested and morphometric analysis was performed on cross-sections. Results Proliferation of smooth muscle cell (SMC) was strongly suppressed in the treatment group, and the ratio of neointima to vein wall was significantly reduced in the treatment group (8 weeks; 0.63 ± 0.08 vs. 0.2 ± 0.08, P < 0.05). Luminal patency was significantly more preserved in the treatment group, and the luminal area was significantly wider in the paclitaxel-treated group compared to the control group (8 weeks; 1.91 ± 0.43 mm2 vs. 5.1 ± 0.43 mm2, P < 0.05). Mean SMC counts measured at 1 and 2 weeks after cutdown were significantly lower in the treatment group (2 weeks; 115 ± 22 vs. 62 ± 22). Paclitaxel was undetectable in systemic circulation (<10 ng/mL). Conclusion Sustained perivascular delivery of paclitaxel with fibrin glue was effective in inhibiting neointimal hyperplasia in rat jugular vein after open cutdown. PMID:28203557

    A 77-year-old woman was admitted due to AV graft thrombosis; given the technical impossibility of performing other native AV fistulas, we chose to insert a tunnelled central venous catheter. Considering the vascular history of the patient, the central venous catheter could not be placed into the internal jugular vein; it was therefore put into the left femoral vein. Following a 3-month-period of the catheter working properly, the patient was hospitalized due to sudden acute pain in the left thigh. In a few days the patient developed an important haematoma with serious anemization in the left lower limb. Ultrasonography showed the presence of a fistula between the left common femoral artery and the femoral vein, leading to the subsequent successful positioning of a stent into the common femoral artery through right trans-femoral access. Angiography examination showed the femoral vein patency along the proximal stretch with respect to the function of the tunnelled venous catheter.

    A method for hemodialysis catheter placement in patients with central thoracic venous stenosis or occlusion is described and initial results are analyzed. Twelve patients, with a mean age of 63.2 years (42-80 years), with central venous stenosis or occlusion, and who required a hemodialysis catheter were reviewed. All lesions were confirmed by helical CT or phlebography. Five patients had stenosis while seven patients were diagnosed with an occlusion of thoracic central veins. All patients were asymptomatic, without sign of superior vena cava syndrome. After percutaneous transstenotic catheterization or guidewire-based recannalization in occlusions, a balloon dilatation was performed and a stent was placed, when necessary, prior to catheter placement. Technical success was 92%. Three patients had angioplasty alone and nine patients had angioplasty with stent placement. Dialysis catheters were successfully inserted through all recannalized accesses. No immediate complication occurred, nor did any patient develop superior vena cava syndrome after the procedure. The mean follow-up was 21.8 months (range, 8-48 months). Three patients developed a catheter dysfunction with fibrin sheath formation (at 7, 11, and 12 months after catheter placement, respectively). Two were successfully managed by percutaneous endovascular approach and one catheter was removed. In conclusion, for patients with central venous stenosis or occlusion and those who need a hemodialysis catheter, catheter insertion can be reliably achieved immediately after endovascular recannalization with acceptable technical and long-term success rates. This technique should be considered as an alternative procedure for placing a new hemodialysis catheter through a patent vein.

    Central venous catheterization is a procedure with a high success rate. However, life-threatening complications are occasionally caused by mechanical injury during the catheterization process. Therefore, surgeons should have sufficient knowledge of the potential complications and the effective use of preventative measures when performing catheterization. We herein review and discuss the mechanical complications previously reported to have occurred in association with central venous catheterization. Comprehensive knowledge about various complication-inducing factors, the ability to make a quick and accurate diagnosis of such complications, and sufficient skill to prevent worsening of these complications can thus help patients from suffering lethal complications due to central venous catheterization.

    Objective To evaluate if body surface temperature close to the central venous catheter insertion area is different when patients develop catheter-related bloodstream infections. Methods Observational cross-sectional study. Using a non-contact infrared thermometer, 3 consecutive measurements of body surface temperature were collected from 39 patients with central venous catheter on the following sites: nearby the catheter insertion area or totally implantable catheter reservoir, the equivalent contralateral region (without catheter), and forehead of the same subject. Results A total of 323 observations were collected. Respectively, both in male and female patients, disregarding the occurrence of infection, the mean temperature on the catheter area minus that on the contralateral region (mean ± standard deviation: -0.3±0.6°C versus -0.2±0.5ºC; p=0.36), and the mean temperature on the catheter area minus that on the forehead (mean ± standard deviation: -0.2±0.5°C versus -0.1±0.5ºC; p=0.3) resulted in negative values. Moreover, in infected patients, higher values were obtained on the catheter area (95%CI: 36.6-37.5ºC versus 36.3-36.5ºC; p<0.01) and by temperature subtractions: catheter area minus contralateral region (95%CI: -0.17 - +0.33ºC versus -0.33 - -0.20ºC; p=0.02) and catheter area minus forehead (95%CI: -0.02 - +0.55ºC versus -0.22 - -0.10ºC; p<0.01). Conclusion Using a non-contact infrared thermometer, patients with catheter-related bloodstream infections had higher temperature values both around catheter insertion area and in the subtraction of the temperatures on the contralateral and forehead regions from those on the catheter area.

    Multiple sclerosis (MS) is a disorder characterized by damage to the myelin sheath insulation of nerve cells of the brain and spinal cord affecting nerve impulses which can lead to numerous physical and cognitive disabilities. The disease, which affects over 500,000 people in the United States alone, is widely believed to be an autoimmune condition potentially triggered by an antecedant event such as a viral infection, environmental factors, a genetic defect or a combination of each. Chronic cerebrospinal venous insufficiency (CCSVI) is a condition characterized by abnormal venous drainage from the central nervous system that has been theorized to have a possible role in the pathogenesis and symptomatology of MS (1). A significant amount of attention has been given to this theory as a possible explanation for the etiology of symptoms related to MS patients suffering from this disease. The work of Dr. Zamboni, et al, who reported that treating the venous stenoses causing CCSVI with angioplasty resulting in significant improvement in the symptoms and quality of life of patients with MS (2) has led to further interest in this theory and potential treatment. The article presented describes endovascular techniques employed to diagnose and treat patients with MS and CCSVI.

    Central venous catheters (CVCs) are extensively used worldwide. Mechanical, infectious and thrombotic complications are well described with their use and may be associated with prolonged hospitalization, increased medical costs and mortality. CVCs account for an estimated 90% of all catheter-related bloodstream infections (CRBSI) and a host of risk factors for CVC-related infections have been documented. The duration of use of CVCs remains controversial and the length of time such devices can safely be left in place has not been fully and objectively addressed in the critically ill patient. Antimicrobial-impregnated catheters have been introduced in an attempt to limit catheter-related infection (CRI) and increase the time that CVCs can safely be left in situ. Recent meta-analyses concluded that antimicrobial-impregnated CVCs appear to be effective in reducing CRI. The authors conducted a prospective, randomized, double-blind study at Johannesburg Hospital over a 4-year period. The study entailed a comparison of standard triple-lumen versus antimicrobial impregnated CVCs on the rate of CRI. Our aim was to determine whether we could safely increase the duration of catheter insertion time from our standard practice of seven days to 14 days, to assess the influence of the antimicrobial impregnated catheter on the incidence of CRI, and to elucidate the epidemiology and risks of CRI. One hundred and eighteen critically ill patients were included in the study which spanned 34 951.5 catheter hours (3.99 catheter years). It was found that antimicrobial catheters did not provide any significant benefit over standard catheters, which the authors feel can safely be left in place for up to 14 days with appropriate infection control measures. The most common source of CRI was the skin. The administration of parenteral nutrition and the site of catheter insertion (internal jugular vein vs subclavian vein) were not noted to be risk factors for CRI. There was no clinical evidence

    This study aimed to investigate the causes and managements of the fractures and migrations of the implantable venous access port catheter (IVAPC). The fracture or migration of IVAPC occurred in 4 patients who were treated between May 2012 and January 2014 in Union Hospital, Wuhan, China. The port catheter leakage was found in 2 cases during drug infusion. Catheters that dislodged to the superior vena cava and right atrium were confirmed by port angiogram. The two dislodged catheters were successfully retrieved by interventional procedures. Catheter fracture occurred in two cases during port removal. One catheter was eventually removed from the subclavian vein through right clavicle osteotomy and subclavian venotomy, and the other removed by external jugular venotomy. Flushing the port in high pressure and injury of the totally implantable venous access port (TIVP) during implantation are usually responsible for catheter displacement. Interventional retrieval procedure can be used if the catheter dislodges to the vena cava and right atrium. Catheter fracture may occur during removal if clipping syndrome occurs or the catheter is sutured very tight during implantation.

    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.

    Abstract Central venous catheter (CVC) insertion is a practical way to assess patients hemodynamic specially in cardiovascular surgery but this relatively simple junior level procedure is not risk free and its common reported complications include; pneumothorax, hydrothorax, hemothorax, local hematoma, cardiac tamponade, vascular injury, thrombosis, embolism, and catheter disruption. Here in this article we are going to present 6 patients with very unusual presentation of CVC complication which was neurological deficit presented by agitation, unconsciousness, disorientation to time and place and hemiparesis. All patients undergone neurologic consult and brain computed tomography. Final diagnosis was brain ischemic damage and finally we kept them on conservative management; fortunately we did not have any permanent damage. PMID:25870645

    Septic shock is an adverse clinical condition resulting in multiple organ failure from global tissue hypoxia. The importance of initial treatment is widely recognized. Thus, guidelines for septic shock recommend early goal-directed therapy (EGDT) during the first six hours of treatment. Central venous oxygen saturation monitoring is useful to maintain adequate tissue oxygen delivery. A newly developed central venous oximetry catheter (PreSep Oximetery Catheter, Edwards Lifesciences) allows continuous and easy monitoring of central venous oxygen saturation. This report shows the usefulness of this catheter in a patient who developed septic shock during an emergency operation for perforated bowel. By using EGDT perioperatively with continuous central venous oximetry, multiple organ failure might be successfully avoided.

In addition to the demographic and clinical characteristics of the patients, we collected data related to central venous catheters (CVCs), hemodialysis (HD) catheters and indwelling arterial catheters (IACs): insertion site; number of catheter days; and types of adverse events. We also characterized the mobility therapy provided. RESULTS: Among the 275 patients evaluated, CVCs were used in 49%, HD catheters were used in 26%, and IACs were used in 29%. A total of 1,268 mobility therapy sessions were provided to patients while they had a catheter in place. Catheter-related adverse events occurred in 20 patients (a total of 22 adverse events): 32%, infection; 32%, obstruction; and 32%, accidental dislodgement. We found that mobility therapy was not significantly associated with any catheter-related adverse event, regardless of the type of catheter employed: CVC-OR = 0.8; 95% CI: 0.7-1.0; p = 0.14; HD catheter-OR = 1.04; 95% CI: 0.89-1.21; p = 0.56; or IAC-OR = 1.74; 95% CI: 0.94-3.23; p = 0.07. CONCLUSIONS: In critically ill patients, mobility therapy is not associated with the incidence of adverse events involving CVCs, HD catheters, or IACs. PMID:26176520

    Central venous catheterization using the Seldinger technique is a well known and often used method. On the other hand, there are also well known complications by needle puncture or by indwelling catheter, there are few reports about a guide wire which got hung up around the tricuspid valve. We report a case in which a guide wire got hung up to the chordae tendineae of the tricuspid valve. To insert the AVA 3Xi (Edwards life science Co. Iervine) from the right internal jugular vein, we inserted a guide wire without ease. Resistance appeared when we tried to remove the wire for 20 cm from the inserted state. The X-ray and the transesophageal echocardiography, showed the guide wire in the right ventricle. As actions to be taken, we advanced the central vein catheter of the EXCV catheter kit (Nippon Sherwood Medical Industries Co., Ltd.) to the tip, and a the guide wire was easily removed. There are many reports of the complication by the central venepuncture, but there are few reports about the guide wire which was entrapped in the vicinity of a tricuspid valve. The tip of the guide wire in this case was bent excessively, but the cause of the damage did not become clear by investigation. When a guide wire became hard to withdraw, we should never withdraw a guide wire blindly, but should search a cause and we should use the material which was matched with the cause.

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

    PubMed Central

    2015-01-01

    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. PMID:26075094

    Purpose To compare pain during injection and efficacy of analgesia of local anesthetics during central venous line placement. Methods Sixty-two patients were studied in a randomized, double-blinded prospective fashion. 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. PMID:22915859

    This study investigated the safety and effectiveness of each type of central venous catheters (CVC) in patients with cancer. We prospectively enrolled patients with cancer who underwent catheterization involving a subclavian venous catheter (SVC), peripherally inserted central venous catheter (PICC), or chemo-port (CP) in our department. From March 2007 to March 2009, 116 patients underwent 179 episodes of catheterization. A SVC was inserted most frequently (46.4%). Fifty-four complications occurred (30.1%): infection in 23 cases, malpositioning or migration of the tip in 18 cases, thrombosis in eight cases, and bleeding in five cases. Malpositioning or migration of the tip occurred more frequently with a PICC (P<0.001); infection occurred more often with a tunneled catheter (P=0.028) and was observed more often in young patients (P=0.023). The catheter life span was longer for patients with solid cancer (P=0.002) than for those with hematologic cancer, with a CP (P<0.001) than a PICC or SVC, and for an indwelling catheter with image guidance (P=0.014) than a blind procedure. In conclusion, CP is an effective tool for long term use and the fixation of tip is important for the management of PICC.

    To compare the rates of central venous stenosis in patients undergoing hemodialysis who underwent disruption of fibrin sheath with percutaneous transluminal angioplasty balloons and those who underwent over-the-wire catheter exchange. This study is a retrospective review of 209 percutaneous transluminal angioplasty balloon disruption and 1304 over-the-wire catheter exchange procedures performed in 753 patients. Approval from the Human Investigations Committee was obtained for this study. Up to 10-year follow-up was performed. A {chi}{sup 2} test was used to compare the rates of central venous stenosis after balloon disruption versus catheter exchange. A t-test was used to compare time to central venous stenosis development. Of the 753 patients in the study, 127 patients underwent balloon disruption of fibrin sheath and 626 had catheter exchange. Within the balloon disruption group, 18 (14.2%) of 127 patients subsequently developed central venous stenosis, compared with 44 (7.0%) of 626 in the catheter exchange group (P < 0.01, {chi}{sup 2} test). Time to central venous stenosis development was approximately 3 years in both groups and not significantly different (1371 and 1010 days, P = 0.20). A total of 25.2% of patients in the balloon disruption group had four or more subsequent catheter exchanges, versus 12.6% in the catheter exchange group (P < 0.01, {chi}{sup 2} test). In conclusions, there is a possible association between percutaneous transluminal angioplasty balloon disruption of fibrin sheath and late-onset central venous stenosis. Because venography was not routinely performed in catheter exchange patients, future randomized studies are necessary to confirm these findings.

    Central venous catheterization is a procedure, which a doctor insert a catheter into the patient’s vein for transfusion. Since there are risks of bleeding from arterial puncture or pneumothorax from pleural puncture. Physicians are strictly required to make needle reach up into the vein and to stop the needle in the middle of vein. We proposed a robot system for assisting the venous puncture, which can relieve the difficulties in conventional procedure, and the risks of complication. This paper reports the design structuring and experimental results of needle insertion manipulator. First, we investigated the relationship between insertion force and angle into the vein. The results indicated that the judgment of perforation using the reaction force is possible in case where the needling angle is from 10 to 20 degree. The experiment to evaluate accuracy of the robot also revealed that it has beyond 0.5 mm accuracy. We also evaluated the positioning accuracy in the ultrasound images. The results displays that the accuracy is beyond 1.0 mm and it has enough for venous puncture. We also carried out the venous puncture experiment to the phantom and confirm our manipulator realized to make needle reach up into the vein.

    With advancing paediatric healthcare, the use of central venous lines has become a fundamental part of management of neonates and children. Uses include haemodynamic monitoring and the delivery of lifesaving treatments such as intravenous fluids, blood products, antibiotics, chemotherapy, haemodialysis and total parenteral nutrition (TPN). Despite preventative measures, central venous catheter-related infections are common, with rates of 0.5-2.8/1000 catheter days in children and 0.6-2.5/1000 catheter days in neonates. Central line infections in children are associated with increased mortality, increased length of hospital and intensive care unit stay, treatment interruptions, and increased complications. Prevention is paramount, using a variety of measures including tunnelling of long-term devices, chlorhexidine antisepsis, maximum sterile barriers, aseptic non-touch technique, minimal line accessing, and evidence-based care bundles. Diagnosis of central line infections in children is challenging. Available samples are often limited to a single central line blood culture, as clinicians are reluctant to perform painful venepuncture on children with a central, pain-free, access device. With the advancing evidence basis for antibiotic lock therapy for treatment, paediatricians are pushing the boundaries of line retention if safe to do so, due to among other reasons, often limited venous access sites. This review evaluates the available paediatric studies on management of central venous line infections and refers to consensus guidelines such as those of the Infectious Diseases Society of America (IDSA).

    The authors analyzed 309 central venous catheters (CVC) inserted in 147 hemodialysis patients before the maturation of the first or new arteriovenous fistula. One clinical manifestations of sepsis after CVC insertion was found. In all, 33.7% of the catheters were removed because of early minor complications: CVC occlusion, inadequate blood flow in CVC, shattered suture and malposition of CVC, fever, signs of infection at the site of CVC insertion, and bleeding at the site of CVC insertion. The most frequently isolated pathogenic bacteria at the tips of the catheters were coagulase-negative staphylococci highly sensitive to vancomycin and gentamicin.

    Central venous stenosis (ST) and thrombosis (TB) related to catheter (KT) had been reported mostly for the subclavian vein. We performed a systematic cavographic study to evaluate the prevalence of these complications in 51 hemodialysis patients with present or previous history of tunneled internal jugular catheter. Each of them had used one or several KT (1.8 +/- 1.4 KT) for a mean 28 +/- 26 month cumulative time (i.e. 43,584 days total exposure time). Fifty percent of the KT were PermCath Quinton and 50% were Twincath (uncuffed) or CS 100 (cuffed) Medcomp. Twenty-seven had no ST (53%, group I), 24 had one or several significant ST (47%, group II) of superior Vena Cava (SVC, n = 4), inferior Vena Cava (IVC, n = 1), Brachio-cephalic Vein (BCV, n = 5) and subclavian vein (SC, n = 10), or a TB of SVC (n = 1), IVC (n = 3), BCV (n = 3), SC (n = 2). This accounts for an incidence of 0.55 ST or TB/1000 patient-days. Five of the twelve subclavian ST and TB had no history of previous subclavian catheter. Comparison between the two groups showed no differences according to age, time on dialysis, diabetes, hematocrit, CRP, cumulative time with catheter, catheter-related infections, type of catheter and anticoagulant treatment. IVC catheter tip's position is an important risk factor for TB and ST (4/6). Twelve group II patients had ST or TB-related symptoms, with a functional AV fistula in 9 cases. Eleven patients underwent repeated percutaneous angioplasty with 4 additional Wallstents and in 2 cases an AV fistula need to be closed. Central venous ST and TB after a jugular KT is extremely frequent, mostly without any symptoms. Consequences on peripheral or central vascular access, cost and poor long-term patency rate of angioplasty are of major importance. These results incite us to further reduce the catheter use in dialysis patients.

    Central venous line placement is a standard procedure in critical care and peri-operative medicine. This procedure can be associated with severe complications. In contrast to the landmark technique, ultrasound-guided punctures can significantly reduce the rate of complications. Patients with a high risk for difficult vascular access include critical care and emergency patients as well as patients on anticoagulation medication and dialysis. Placement of central venous catheters can be difficult in ventilated patients and if there has been prior surgery in the puncture area. In children and small infants central venous access can also be challenging due to the anatomical relationship in the head and neck region. Puncture techniques are explained briefly by means of ultrasound anatomy. Typical ultrasonographic images visualize pathological findings in order to identify dangers and complications in central venous catheterization.

    Although it can be prevented, catheter-related bacteremia is common and dangerous. The antiseptics most widely used during insertion of peripheral venous catheters (PVCs) include povidone iodine, alcohol, and chlorhexidine. Another widely used antiseptic is a solution of 0.057 g sodium hypochlorite. This pilot study explored the contamination rate of the PVC tip inserted after skin decontamination with sodium hypochlorite. Culture analysis of the tips of the PVCs inserted into the 42 participants showed 7 (16.7%) colonized catheters. The results of this pilot study suggest taking into serious consideration the assessment of this antiseptic in randomized experimental studies.

    BACKGROUND AND OBJECTIVE: Central venous catheters in the NICU are associated with significant morbidity and mortality because of the risk of central line–associated bloodstream infections (CLABSIs). The purpose of this study was to determine the effect of catheter dwell time on risk of CLABSI. METHODS: Retrospective cohort study of 13 327 infants with 15 567 catheters (93% peripherally inserted central catheters [PICCs], 7% tunneled catheters) and 256 088 catheter days cared for in 141 NICUs. CLABSI was defined using National Health Surveillance Network criteria. We defined dwell time as the number of days from line insertion until either line removal or day of CLABSI. We generated survival curves for each week of dwell time and estimated hazard ratios for CLABSI at each week by using a Cox proportional hazards frailty model. We controlled for postmenstrual age and year, included facility as a random effect, and generated separate models by line type. RESULTS: Median postmenstrual age was 29 weeks (interquartile range 26–33). The overall incidence of CLABSI was 0.93 per 1000 catheter days. Increased dwell time was not associated with increased risk of CLABSI for PICCs. For tunneled catheters, infection incidence was significantly higher in weeks 7 and 9 compared with week 1. CONCLUSIONS: Clinicians should not routinely replace uninfected PICCs for fear of infection but should consider removing tunneled catheters before week 7 if no longer needed. Additional studies are needed to determine what daily maintenance practices may be associated with decreased risk of infection, especially for tunneled catheters. PMID:26574587

    Patients with difficult intravenous access (DIVA) often experience discomfort because of failed attempts to place peripheral venous catheters (PVCs); however, ultrasound guidance may improve this problem with catheter placement. The aim of this study was to evaluate the use of ultrasound when operated by nurse anesthetists for these patients. This prospective observational study with a pre/post design focused on inpatients with DIVA referred for PVC placement, a service provided by nurse anesthetists in most Scandinavian hospitals. The rate of success, procedure time, number of skin punctures, discomfort, catheter size, location, and incidence of central venous catheter placement are reported before and after implementation of a training program and a mobile service using ultrasound to place difficult-to-place PVCs. The success rate increased from 0% (0 of 33 patients) to 83% (58 of 70 patients) with ultrasound. Procedure time was reduced from 20 to 10 minutes, discomfort was unchanged, and the median number of skin punctures decreased from 3 to 2. The incidence of central venous catheter placement dropped from 34% to 7%. Implementation of a training program and a mobile service in which nurse anesthetists performed ultrasound-guided PVC placement improved the success rate and quality of care in patients with DIVA.

  2. Noninvasive measurement of central venous pressure

    A technique for the noninvasive measurement of CVP in man was developed. The method involves monitoring venous velocity at a point in the periphery with a transcutaneous Doppler ultrasonic velocity meter while the patient performs a forced expiratory maneuver. The idea is the CVP is related to the value of pressure measured at the mouth which just stops the flow in the vein. Two improvements were made over the original procedure. First, the site of venous velocity measurement was shifted from a vein at the antecubital fossa (elbow) to the right external jugular vein in the neck. This allows for sensing more readily events occurring in the central veins. Secondly, and perhaps most significantly, a procedure for obtaining a curve of relative mean venous velocity vs mouth pressure was developed.

    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.

    Abstract Objective: To describe a case of neonatal atrial flutter after the insertion of an intracardiac umbilical venous catheter, reporting the clinical presentation and reviewing the literature on this subject. Case description: A late-preterm newborn, born at 35 weeks of gestational age to a diabetic mother and large for gestational age, with respiratory distress and rule-out sepsis, required an umbilical venous access. After the insertion of the umbilical venous catheter, the patient presented with tachycardia. Chest radiography showed that the catheter was placed in the position that corresponds to the left atrium, and traction was applied. The patient persisted with tachycardia, and an electrocardiogram showed atrial flutter. As the patient was hemodynamically unstable, electric cardioversion was successfully applied. Comments: The association between atrial arrhythmias and misplaced umbilical catheters has been described in the literature, but in this case, it is noteworthy that the patient was an infant born to a diabetic mother, which consists in another risk factor for heart arrhythmias. Isolated atrial flutter is a rare tachyarrhythmia in the neonatal period and its identification is essential to establish early treatment and prevent systemic complications and even death.

    Umbilical venous catheterization has become a widely accepted intravenous route for premature babies. These catheters allow administration of parenteral nutrition and medication and facilitate blood sampling. Besides these benefits, they also have significant potential complications like portal vein thrombosis, infection, vascular or hepatic injury, arrhythmia and sepsis. One of the rare but important complication is extravasation of the fluids due to misplacement of the catheter. The typical symptoms of this condition are sudden deterioration, hepatic enlargement, hematocrit drop, hypotension and abdominal distension. We herein present a premature newborn with unusual acute abdomen findings suggesting a surgical pathology after the extravasation of total parenteral nutrition into the abdomen.

    Thirty-one critically ill patients with acute respiratory failure and circulatory shock were divided into three groups. Group 1 included 11 patients with an inserted mixed venous saturation (SvO2) catheter using three-reference wavelengths and characterized by one transmitting and one detecting fiberoptic filament (Oximetrix opticath catheter); group 2 included eight patients with an inserted SvO2 catheter using two-reference wavelengths and characterized by one transmitting and one detecting fiberoptic filament; (Edwards sat-one catheter); group 3 included 12 patients with an inserted SvO2 catheter using two-reference wavelengths and characterized by one transmitting and two detecting fiberoptic filaments. Once calibration procedures were performed, SvO2 measured by the catheter and by an hemoximeter OSM 3 (reference value) were compared following each therapeutic intervention. Over a period of 1.5 to 6 hours during which the hematocrit value remained unchanged, 119 measurements were obtained in group 1, 91 in group 2 and 181 in group 3. The dispersion of SvO2 values was much more pronounced with the two-reference wavelength systems using either one or two detecting fiber optic filaments, and the correlation coefficient was significantly higher with the three-reference wavelength system (r = 0.970 for the Oximetrix catheter vs r = 0.855 for the Edwards catheter and r = 0.826 for the Spectramed catheter, p less than 0.001). After 24 hours, the spontaneous drifts in the two-reference wavelength systems, using either one or two detecting fiber optic filaments (expressed as the SvO2 value measured by the catheter minus the reference SvO2 value) were significantly higher than the spontaneous drift in the three-reference wavelength system (9.3 +/- 7 percent for the Edwards catheter and +/- 6 +/- 4.1 percent for the Spectramed catheter vs 3.3 +/- 3.1 percent for the Oximetrix catheter, p less than 0.05). This study shows that a three-wavelength system is more accurate

    Introduction: Determining the proper angle for inserting central venous catheter (CV line) is of great importance for decreasing the complications and increasing success rate. The present study was designed to determine the proper angle of needle insertion for internal jugular vein catheterization. Methods: In the present case series study, candidate patients for catheterization of the right internal jugular vein under guidance of ultrasonography were studied. At the time of proper placing of the catheter, photograph was taken and Auto Cad 2014 software was used to measure the angles of the needle in the sagittal and axial planes, as well as patient’s head rotation. Result: 114 patients with the mean age of 56.96 ± 14.71 years were evaluated (68.4% male). The most common indications of catheterization were hemodialysis (55.3%) and shock state (24.6%). The mean angles of needle insertion were 102.15 ± 6.80 for axial plane, 36.21 ± 3.12 for sagittal plane and the mean head rotation angle was 40.49 ± 5.09. Conclusion: Based on the results of the present study it seems that CV line insertion under the angles 102.15 ± 6.80 degrees in the axial plane, 36.21 ± 3.12 in the sagittal plane and 40.49 ± 5.09 head rotation yield satisfactory results.

    Venepuncture and the insertion of peripheral venous catheters are common tasks in health care, and training in these procedures is included in nursing programmes. Evidence of nursing students' knowledge and skills in these procedures is limited. The main aim of this study was to assess nursing students' knowledge and skills when performing venepuncture and inserting peripheral venous catheters. Potential associations between level of knowledge and skills, self-training, self-efficacy, and demographic characteristics were also investigated. The assessment was performed by lecturers at a university college in Sweden using the two previously tested instruments "Assess Venepuncture" and "Assess Peripheral Venous Catheter Insertion". Between 81% and 100% of steps were carried out correctly by the students. The step with the highest rating was "Uses gloves", and lowest rating was 'Informs the patients about the possibility of obtaining local anaesthesia'. Significant correlations between degree of self-training and correct performance were found in the group of students who registered their self-training. No associations between demographic characteristics and correct performances were found. Assessing that students have achieved adequate levels of knowledge and skills in these procedures at different levels of the nursing education is of importance to prevent complications and support patient safety.

    Functional outcome of venous stent placement for the management of acute iliofemoral deep vein thrombosis (DVT) following catheter-directed thrombolysis (CDT), remain undefined. The purpose of this study was to assess immediate and intermediate term outcomes among patients treated with venous stenting following CDT in patients with proximal lower limb DVT. Thirty consecutive patients aged between 20-70 years with proximal lower limb DVT formed the study group. The mean duration of CDT done with streptokinase was 4.5 ± 1.3 days. Patients with residual venous obstruction and/or large clot burden were treated further with venous angioplasty and/or stenting. Primary endpoint was to evaluate the safety, efficacy and patency of venous stenting in the management of incomplete result following CDT. After 12 months, post-thrombotic syndrome (PTS) was assessed clinically using Villalta scale and deep venous patency was assessed through duplex ultrasound. We studied 8 (5 female and 3 male) patients with 9 (3 left and 6 right) limb involvement and 13 stent (4 balloon expandable and 9 self expandable) placement. All patients improved clinically immediately following venous stenting. Technical success was achieved in all patients. One patient developed pulmonary embolism during course of hospital stay. One patient had stent thrombosis and PTS and another patient died due to carcinoma breast during follow-up. Deep venous stenting is an effective mode of treatment in proximal acute lower limb DVT with high late patency rate up to 1-year.

    Central venous catheter placement is indicated in many situations, and an increasing number of patients require temporary and long-term central catheters. Frequently, patients who have undergone multiple central veins catheterizations develop complete and diffuse venous occlusion, and this constitutes a difficult-to-manage clinical problem. We report a case of a 20-year-old patient who was referred to our department for central venous line placement who manifested bilateral femoral, jugular, and subclavian veins occlusion. A central venous catheter was implanted through a cervical collateral vein, targeting on and puncturing an angioplasty balloon, and advanced into the collateral vein through a transhepatic venous access.

    Purpose: We describe the technique, efficacy, and complications of fluoroscopy-guided implantation of a central venous access device using a peripherally accessed system (PAS) port via the forearm. Methods: Beginning in July 1994, 105 central venous access devices were implanted in 104 patients for the long-term infusion of antibiotics or antineoplasmic agents, blood products, or parenteral nutrition. The devices was inserted under fluoroscopic guidance with real-time venography from a peripheral route. Results: All ports were successfully implanted. There were no procedure-related complications. No thrombosis or local infection was observed; however, in six patients catheter-related phlebitis occurred. Conclusion: Fluoroscopy-guided implantation of a central venous access device using a PAS port via the forearm is safe and efficacious, and injection of contrast medium through a peripheral IV catheter before introduction of the catheter helps to avoid catheter-related phlebitis.

    An unusual case of central venous catheter (CVC)-related thrombosis during supine surgery in the prone position is presented. A 76-year-old woman was scheduled for elective surgery to repair a broken lumbar instrument. A single-lumen CVC was inserted via the right internal jugular vein. Surgery was performed in the prone position, with the patient's face directed downward in the standard median position (i.e., no rotation), but with slight forward flexion at the neck. After the surgery, the external jugular vein was dilated, and a postoperative X-ray revealed an infiltrative shadow in the right thoracic cavity. Because cervical echography showed dilated cervical veins with a "moyamoya-type" echo, possibly indicating a thrombus, contrast-enhanced computed tomography was performed, revealing a venous thrombus in the right internal jugular vein. An internal jugular venous-velocity measurement suggested that her slightly flexed neck position and her prone position during surgery may have kinked the internal jugular vein, causing engorgement with venous blood. The presence of the internal jugular venous catheter may have created thrombogenic conditions. A patient's position during surgery can reduce deep venous-flow velocity, and venous blood may stagnate, contributing greatly to thrombogenicity. We should consider a patient's position during surgery as a risk factor for thrombus formation, and a careful preoperative evaluation should be made as to which route should be chosen for CVC.

    In clinical practice, both a thin-walled introducer needle and catheter-over-needle technique can be used to allow insertion of a guidewire during central venous catheterisation using the Seldinger technique. We compared the incidence of catheterisation-related complications (arterial puncture, haemothorax, pneumothorax, haematoma and catheter tip malposition) and insertion success rate for these two techniques in patients requiring right-sided subclavian central venous catheterisation. A total of 414 patients requiring infraclavicular subclavian venous catheterisation were randomly allocated to either a thin-walled introducer needle (needle group, n = 208) or catheter-over-needle technique (catheter group, n = 206). The catheterisation-related complication rate was lower in the needle group compared with the catheter group (5.8% vs. 15.5%; p = 0.001). Overall insertion success rates were similar (97.1% and 92.7% in the needle and catheter groups respectively; p = 0.046), although the first-pass success rate was higher in the needle group (62.0% vs. 35.4%; p < 0.001). We recommend the use of a thin-walled introducer needle technique for right-sided infraclavicular subclavian venous catheterisation.

    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.

    Implanted venous access devices (IVAD) are routinely used in oncologic patients. Thrombotic complication is a source of morbidity. During one year 246 patients with different solid neoplastic diseases received IVAD for chemotherapy administration. Two hundred forty-nine IVAD were placed percutaneously or by surgical cutdown. IVAD were flushed immediately after implantation with 3-5 mL of heparinized saline (100 U/mL). No monthly flush was required. A prospective evaluation of thrombotic complications was realised. in event of catheter dysfunction and/or clinical symptoms of phlebitis, a catheter opacification and/or a Doppler ultrasonography were performed. Twenty-three catheter dysfunctions were noted, corresponding to 13 catheter occlusions. Twelve patients presented clinical symptoms of phlebitis. Eleven venous thrombosis were diagnosed in this group; 10 by echo-Doppler and one by scanography. A unvaried statistic analysis using Fisher's test was performed to detect risk factors. Two factors were identified: the position of catheter tip above T4 (p < 0.001) and mediastinal or cervical lymph nodes larger than 6 cm (p < 0.001). The first increased the risk of catheter occlusion and the second increased the risk of phlebitis.

    Thrombosis of tunneled central venous catheters (CVC) in hemodialysis (HD) patients is common and it can lead to the elimination of vascular sites. This study aimed to evaluate the incidence of thrombotic obstruction of tunneled CVC in HD patients and the efficacy of occlusion treatment with alteplase use, and identify factors associated with thrombotic occlusion. It was a prospective cohort study performed in two centers which evaluated the diagnosis and treatment of thrombotic occlusion of CVC in HD patients for 24 consecutive months. The catheter occlusion was defined as the difficulty infusing or withdrawing fluid from their paths. Alteplase dose was infused to fill the lumen of the occluded catheter and remained for 50 min. As there was no obstruction of the catheter, the procedure was repeated. Three hundred and thirty-nine CVC in 247 patients were evaluated and followed, totalling 67,244 CVC-days. One hundred fifty-seven patients had only one CVC, 88 patients had two CVC during the study, and two patients had three CVC. The median age was 58 (47-66) years, patients were predominantly men (54%), with diabetic nephropathy as the main cause of chronic kidney disease (44%), the internal jugular vein as the main site of implantation (82%), and duration of dialysis before CVC implantation of 119 (41.5 to 585.5) days. Eight hundred and fifteen occlusion episodes were diagnosed (12 episodes/1000 CVC-days), with primary success with alteplase in 596 episodes (77%) and secondary in 81 cases (10%). In 99 episodes (13%), success was not achieved after the second dose of alteplase. Two hundred and thirty CVC were removed during the study and the removal causes were arteriovenous fistula use in 88 patients (38.3%), infectious and mechanical complications in 89 (38.7%) and 21 (9.1%), respectively, and others (transplantation, transfer, or death) in 32 patients (13.9%). Adverse effects were also not observed. In the multivariate analysis, we identified the greatest number

    Central venous access for acute renal failure has been used for a number of years. The femoral vein and, more recently, the subclavian vein have been the routes of access. This technique has many advantages, however, it also has some significant limitations. We have recently been using a catheter for long- as well as short-term hemodialysis. The catheter is placed by means of a short incision through an opening in the internal jugular vein, and maneuvered so that the tip lies in the superior portion of the right atrium. After dialysis, the catheter is filled with heparin. The catheter then requires no additional care between between hemodialysis sessions. We have reported an experience of 50 patients in whom this catheter has been used. The complications have been remarkably few, and none were serious or fatal. At present, the patient using the catheter for the longest period of time has had it in position for approximately 19 months. We believe this technique provides a significant new choice among the ways in which hemodialysis can be achieved for short- or long-term needs.

    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. PMID:25032055

    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.

    Choosing an appropriately sized vein reduces the risk of venous thromboembolism associated with peripherally inserted central catheters. This observational study described the diameters of the brachial, basilic, and cephalic veins and determined the effect of patient factors on vein size. Ultrasound was used to measure the veins of 176 participants. Vein diameter was similar in both arms regardless of hand dominance and side. Patient factors-including greater age, height, and weight, as well as male gender-were associated with increased vein diameter. The basilic vein tended to have the largest diameter statistically. However, this was the case in only 55% of patients.

    This paper describes a computer program to utilize electromagnetic tracking guidance during insertion of peripherally inserted central catheters. Placement of a Peripherally Inserted Central Catheter (PICC) line is a relatively simple, routine procedure in which a catheter is inserted into the veins of the lower arm and threaded up the arm to the vena cava to sit just above the heart. However, the procedure requires x-ray verification of the catheter position and is usually done under continuous fluoroscopic guidance. The computer program is designed to replace fluoroscopic guidance in this procedure and make PICC line placement a bedside procedure. This would greatly reduce the time and resources dedicated to this procedure. The physician first goes through a quick registration procedure to register the patient space with the computer screen coordinates. Once registration is completed, the program provides a continuous, real-time display of the position of the catheter tip overlaid on an x-ray image of the patient on an adjacent computer screen. Both the position and orientation of the catheter tip is shown. The display is very similar to that shown when using fluoroscopy.

    For head and neck reconstruction after tumor ablation surgery, free flaps are mostly the chosen treatment modality for most of the centers. Coping with venous insufficiency and increasing venous outflow of the flap during this process increases the success rate. To increase venous outflow, triple-lumen central venous catheter is inserted to one of the donor veins of the flap that has venous insufficiency and one intact vein anastomosis.

    Ethanol lock therapy has been implemented to prevent infections of central venous catheters as well as to treat infections. Fungal catheter-associated blood stream infections are historically more difficult to treat and have required removal of central venous catheters. We report the largest case series to date, successfully treating 5 of 7 fungal catheter-associated blood stream infections with ethanol lock therapy and systemic echinocandin administration.

    PubMed

    The force of cardiac contraction is strongly influenced by myocardial fibre length at the beginning of systole. Because the length of cardiac sarcomers and muscle fibres primarily depends on the end-diastolic ventricular volume, filling pressures a priori can only act as indirect parameters of cardiac preload. Central venous pressure (CVP) gives information on right ventricular end-diastolic pressure, which parallels changes in left ventricular end-diastolic pressure as long as ventricular function is not impaired. Since the pressure-volume relationship of cardiac ventricles is not linear and shows great variability, filling of the ventricles cannot be directly derived from end-diastolic pressure. Further limitations of CVP as a surrogate variable of preload are caused by the influence of intrathoracic and intra-abdominal pressures. A valid parameter of preload should describe the relationship between preload and stroke volume as given by the Frank-Starling law. Furthermore, estimates of cardiac preload should enable prediction of fluid responsiveness. Many studies have demonstrated that under clinical conditions CVP cannot meet these demands and thus does not appear to be a useful predictor of cardiac preload. Variables which more directly represent end-diastolic ventricular volume (e.g. intrathoracic blood volume or end-diastolic ventricular area) offer a higher validity as estimates of cardiac preload. Furthermore, dynamic parameters of ventricular preload, such as pulse pressure variation or stroke volume variation, seem to be more predictive of volume responsiveness in ventilated patients than CVP. These limitations, however, do not impair the importance of CVP as the downstream pressure of the systemic venous system.

    Portacath implantation with introduction of a catheter into the superior vena caval system is a commonly performed procedure. Catheterization of the internal jugular vein can be difficult due to anatomical variation, individual patient morphology, or as a result of previous catheterization. Use of 2D ultrasonography facilitates localization of the internal jugular vein and decreases the risks of catheter placement.

The patients ranged in age from 3 to 148 days (mean of 43.3 and standard deviation of 47.5) and in weight from 1110 to 4000 grams (mean of 3182 grams and standard deviation 767.2 grams). Overall successful catheterization rate was 94.5%. Complications included a pneumothorax that needed pleural drainage, one self-limited femoral artery spasm and one stenosis of femoral vein that did not require any treatment. The mean catheterism time was 6.64 days (deviation of 3.84 days), and the causes of removal were end of treatment in 8 patients, accidental removal in 5, infectious suspicion in 2 and limb edema in 2. Seldinger technique may be a useful approach for central venous catheterization in neonates. Careful catheterization, extensive experience and appropriate selection of material, help to keep the risk of complications low.

In an obese person, one week after the implantation of a totally implantable venous access, a chest X-ray showed that the catheter was too short. In the operative room, at the time of the second intervention, the radioscopy did not find this anomaly. The subcutaneous injection port was positioned too low. When the patient was in a supine position, the subcutaneous injection port was in the correct position but when she was in an upright position, the breast descended and pulled down the subcutaneous injection port and the catheter.

    ABSTRACT Objective To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein. Methods Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons. The primary endpoints assessed were early postoperative complications, occurring within 30 days after implantation. The evaluation of patient satisfaction was based on a specific questionnaire used in previous studies. Results In all cases, ultrasound-guided puncture of the basilic vein was feasible and the procedure successfully completed. Early complications included one case of basilic vein thrombophlebitis and one case of pocket infection that did not require device removal. Out of 35 patients interviewed, 33 (94.3%) would recommend the device to other patients. Conclusion Implanting brachial ports is a feasible option, with low intraoperative risk and similar rates of early postoperative complications when compared to the existing data of the conventional technique. The patients studied were satisfied with the device and would recommend the procedure to others. PMID:28076593

    Its peripheral vein puncture point, safe insertion procedure and high rate of success have made the peripherally inserted central catheter (PICC) a particularly suitable medical device for cancer patients who require long-term intravenous chemotherapy. PICC can help avoid the pain of repeat punctures as well as reduce incidence of cytotoxic drug extravasation-induced phlebitis and tissue necrosis. With PICC, patient activity is not limited, which improves quality of life. This paper reported on complications and subsequent nursing care provided to 400 cancer patients who received PICC in our center between September 2007 and October 2008. A total of 395 cases had successful PICC insertion on the first attempt and 5 cases achieved success immediately following the second insertion attempt (overall success rate: 98.8%). The average catheter dwell-in time was 122 days (range 2-350 days), during which time no patient required repeat puncture. During the insertion process, arrhythmia occurred in 1.5% (6/400), difficult catheter propelling in 3.75% (15/400), and excessive oozing of blood in 0.3% (1/400) of subjects. During the catheter dwell-in period, sensitizing dermatitis occurred in 8% (38/400), mechanical phlebitis in 7.5% (30/400), catheter occlusion in 9.5% (38/400) (including 2% [8/400] complete and 7.5% [30/400] partial occlusions), catheter associated hematogenous infection in 3% (12/400) and venous thrombosis in 2% (8/400) of subjects. All complications were well controlled with active and effective management. In conclusion, the safety of PICC can be maximized and complications reduced when nurses fully evaluate patients prior to their operation, strictly adhere to PICC operating guidelines, detect complications early, and manage problems promptly.

    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/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

    Central venous catheterization with ultrasound guidance was performed on 41 patients with terminal stage malignant tumors--112 consecutive insertions at our hospital. We performed a total of 112 consecutive insertions: 30 with the skin marking method and 82 with the real time echo guidance method. Catheter insertion was performed to the internal jugular vein in 24, the supra-clavicular approach of the subclavian vein in 4, the infra-clavicular approach of the subclavian vein in 37 and the femoral vein in 47. The success rate was 85.7% (96/112 insertions), and the mean insertion time was 2.2 minutes. The complication rate was 4.5%: arterial puncture for 3 insertions, and mal-position for 2 insertions. In this examination, it was confirmed that central venous catheterization with ultrasound guidance could be performed safely and briefly in such patients.

    OBJECTIVES: With the apparent increase in venous thromboembolism noted in the pediatric population, it is important to define which children are at risk for clots and to determine optimal preventative therapy. The purpose of this study was to determine the risk factors for venous thromboembolism in pediatric patients with central venous line placement. METHODS: This was an observational, retrospective, case-control study. Control subjects were patients aged 0 to 18 years who had a central venous line placed. Case subjects had a central line and a radiographically confirmed diagnosis of venous thromboembolism. RESULTS: A total of 150 patients were included in the study. Presence of multiple comorbidities, particularly the presence of a congenital heart defect (34.7% case vs. 14.7% control; p < 0.005), was found to put pediatric patients at increased risk for thrombosis. Additionally, the administration of parenteral nutrition through the central line (34.7% case vs. 18.7% control; p = 0.03) and location of the line increased the risk for clot formation. CONCLUSIONS: With increased awareness of central venous line–related thromboembolism, measures should be taken to reduce the number and duration of central line placements, and further studies addressing the need for thromboprophylaxis should be conducted.

    OBJECTIVES To describe patterns of use, care practices, and outcomes related to peripherally inserted central catheter (PICC) use in skilled nursing facilities (SNFs). DESIGN Prospective cohort study. SETTING Two community SNFs. PARTICIPANTS Adult SNF residents with PICCs (N = 56). MEASUREMENTS Information on indication for PICC use, device characteristics (e.g., lumens, gauge), and participant data (comorbidities, medications) were obtained from medical records. Care practices (e.g., frequency of flushing, dressing care) and problems related to PICCs were recorded. Major (central line–associated bloodstream infection, venous thromboembolism, catheter dislodgement) and minor (migration, dressing disruption, lumen occlusion, exit site infection) complications and process measures (flushing of PICC, assessment of necessity) were recorded. Bivariate analyses with t-tests, chi-square tests, or Fischer exact tests were used for continuous and categorical data. RESULTS Participants were enrolled from two SNFs. The most common indication for PICC use was intravenous antibiotic delivery. The average PICC dwell time was 43 days, and most devices were single-lumen PICCs. Major and minor complications were common and occurred in 11 (20%) and 18 (32%) participants, respectively. Occlusion (23%, n = 13), accidental dislodgement (12%, n = 7), and dressing disruption (11%, n = 6) were the commonest complications observed. Documentation regarding catheter care practices occurred in 41% of cases. CONCLUSION Quality improvement efforts that seek to benchmark practice, identify gaps, and institute efforts to improve PICC care and practice in SNFs appear necessary. PMID:26312402

    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.

    Treatment of chronic diseases in children is a special medical problem. Maintaining constant access to the central vascular system is necessary for long-term hemato-oncological and nephrological therapies as well as parenteral nutrition. Providing such access enables chemotherapic treatment, complete parenteral nutrition, long-term antibiotic therapy, hemodialysis, treatment of intensive care unit patients, monitoring blood pressure in the pulmonary artery and stimulation of heart rate in emergency situations as well as treatment of patients suffering from complications, especially when chances of access into peripheral veins are exhausted. Continuous access to the central vascular system is desirable in the treatment of chronically ill children. Insertion of a central venous catheter line eliminates the unnecessary pain and stress to a child patient accompanying injection into peripheral vessels. In order to gain long-term and secure access to the central venous system, respecting the guidelines of the Center for Disease Control and Prevention contained in the updated 'Guidelines for the Prevention of Intravascular Catheter-Related Infections' is necessary.

    Central venous catheter-related fungemia are increasing in the last years, also due to rare fungi. We report the case of a Candida utilis catheter-related bloodstream infection in a patient with metastatic carcinoma of the bladder and a long term totally implanted venous catheter. The diagnosis was done by paired blood cultures and differential time to positivity. The Candida species was rapidly identified by MALDI-TOF mass spectrometry. The patient was successfully treated with anidulafungine. PMID:25473600

    In this work we report our initial experience on the utilisation of the spiral tomodensitometry in the study of the vascular complications due to the catheterization of the internal jugular vein. We present the results of a systematic search of vascular lesions after removal of an indwelling catheter in a group of 18 patients and describe a few cases of acute complications where the use of TDMS has been very useful in the diagnostic workout. The results confirm the risks associated with the catheterization of the internal jugular vein, showing a frequency of lesions of various degree in about 50% of the cases. Moreover, we discuss some aspects of the thrombotic complications in the patients carrying a central venous catheter and the advantages of the diagnostic application of the spiral tomodensitometry.

    Peripherally inserted central catheters (PICC) have the advantage of limiting the risk of accidents during installation and are easy to remove. Its use in oncology remains debated because of possible infectious complications. We analyzed 52 PICC in patients with hematological tumor from Nice Hospital. An installation failure was noted in 5.8% of cases. After a follow-up of 15 months, the complication rate was 26.9%, mainly mechanical complications: obstruction (13.5%) or accidental removal (9.6%). The organic complications such as infection or thrombophlebitis represented 3.8%. The median duration was 26 days [2-291]. The longest duration was associated with PICC for chemotherapy (median: 58 days). Frequent blood samples (above: 2 week) were associated with lower duration (median: 23 days). In conclusion, PICC represent a simple and effective alternative to intra-venous central devices in onco-hematology. However, physicians have to focus on short-course treatment.

    To compare prospective between insertion of non-cuffed dual lumen catheter in the external jugular vein and other central veins for hemodialysis (HD), we studied 68 chronic dialysis patients randomly allocated into two groups: one with external jugular vein catheterization as access for HD and another with other central venous catheterization, internal jugular or subclavian vein. Our results showed there were no significant differences regarding successful cannulation, com-plications, total numbers of dialysis, development of pain and infection at the site of cannulation, patency rate of the catheters, and efficacy of hemodialysis between both groups. In addition, the patency of the catheter in the external jugular vein was not affected by previous cannulation of other central veins. In contrast, there was a significant correlation between numbers of attempts for cannulation in both groups and development of hematoma and infection, (p< 0.05). In conclusion, our results showed that the external jugular vein may be an alternative for other central veins for insertion of temporary non-cuffed hemodialysis catheter.

    Central venous catheterization (CVC) is often necessary during initial trauma resuscitations, but may cause complications including catheter-related blood stream infection (CRBSI), deep venous thrombosis (DVT), pulmonary emboli (PE), arterial injury, or pneumothoraces. Our primary objective compared subclavian versus femoral CVC complications during initial trauma resuscitations. A retrospective review (2010-2011) at an urban, Level-I Trauma Center reviewed CVCs during initial trauma resuscitations. Demographics, clinical characteristics, and complications including: CRBSIs, DVTs, arterial injuries, pneumothoraces, and PEs were analyzed. Fisher's exact test and Student's t test were used; P ≤ 0.05 was considered statistically significant. Overall, 504 CVCs were placed (subclavian, n = 259; femoral, n = 245). No difference in age (47 ± 22 vs 45 ± 23 years) or body mass index (28 ± 6 vs 29 ± 16 kg/m(2)) was detected (P > 0.05) in subclavian vs femoral CVC, but subclavian CVCs had more blunt injuries (81% vs 69%), greater systolic blood pressure (95 ± 55 vs 83 ± 43 mmHg), greater Glasgow Coma Scale (10 ± 5 vs 9 ± 5), and less introducers (49% vs 73%) than femoral CVCs (all P < 0.05). Catheter related arterial injuries, PEs, and CRBSIs were similar in subclavian and femoral groups (3% vs 2%, 0% vs 1%, and 3% vs 3%; all P > 0.05). Catheter-related DVTs occurred in 2 per cent of subclavian and 9 per cent of femoral CVCs (P < 0.001). There was a 3 per cent occurrence of pneumothorax in the subclavian CVC population. In conclusion, both subclavian and femoral CVCs caused significant complications. Subclavian catheter-related pneumothoraces occurred more commonly and femoral CRBSIs less commonly than expected compared with prior literature in nonemergent scenarios. This suggests that femoral CVC may be safer than subclavian CVC during initial trauma resuscitations.

Am J Physiol Heart Circ Physiol 288: H2995–H3000, 2005; doi:10.1152/ajpheart.00703.2004.—The purpose of this study is to evaluate the feasibility of percutaneous antegrade myocardial gene transfer (PAMGT). A consistent and safe technique for in vivo gene transfer is required for clinical application of myocardial gene therapy. PAMGT with concomitant coronary venous blockade was performed in 12 swine. The myocardium was preconditioned with 1 min of occlusion of the left anterior descending and left circumflex arteries. The anterior interventricular vein was occluded during left anterior descending artery delivery, and the great cardiac vein at the entrance of the middle cardiac vein was occluded during left circumflex artery delivery. With arterial and venous balloons inflated (3 min) and after adenosine (25 μg) injection, PAMGT was performed by antegrade injection of an adenoviral solution (1 ml of 1011 plaque-forming units in each coronary artery) carrying β-galactosidase or saline through the center lumen of the angioplasty balloon. In one set of animals, PAMGT was performed with selective coronary vein blockade (n = 9); in another set of animals, PAMGT was performed without coronary vein blockade (n = 5). At 1 wk after gene delivery, the animals were killed. Quantitative β-galactosidase analysis was performed in the left and right ventricular walls. PAMGT was successfully performed in all animals with and without concomitant occlusion of the coronary veins. Quantitative β-galactosidase analysis showed that PAMGT with coronary blockade was superior to PAMGT without coronary blockade. β-Galactosidase activity increased significantly in the

  4. Are chest X-rays mandatory following central venous recatheterization over a wire?

    Exchange of a central venous catheter (CVC) over a guidewire is a frequent clinical procedure, especially in surgical intensive care units. At most hospitals, a chest X-ray (CXR) is obtained routinely after recatheterization to confirm accurate catheter placement and to rule out complications such as pneumothorax. We hypothesized that the incidence of complications after central venous recatheterization over a guidewire is too low to justify automatic performance and the associated expense of a routine postprocedure CXR. Initially we undertook a retrospective study of a total of 295 patients with a Swan-Ganz catheter (SGC), of which 92 SGCs were exchanged over a guidewire for a CVC between July 1, 1994, and June 30, 1996, at a university-affiliated community hospital. Age, gender, duration of SGC placement, type of central catheter used for exchange with the SGC, and CXRs and their reports were noted. From July 1, 1996, to October 1, 1997, the study has been continued prospectively. Thus far, in this ongoing investigation, we have identified 505 patients (201 prospective) who had a SGC placed, 210 (116 prospective) of whom had their SGC removed electively, leaving the SGC introducer in place for advancement of a guidewire, and subsequent replacement by a CVC. Of all the patients with a SGC, 40 per cent had the SGC replaced with a CVC over a guidewire, and follow-up CXRs and their reports confirmed that all exchanged triple lumen catheter tips were appropriately positioned in the superior vena cava with zero complications. With the advent of managed care, a savings of $115/CXR (one view X-ray and reading cost at our hospital) would be gained without the added risk of radiation exposure to the patient if a CXR were not mandatory after an uncomplicated guidewire replacement of a central line. It appears from these data that a CXR is not justified as a routine study after replacement of all CVCs over a wire from the standpoints of both patient risk and expense

    2013-08-01

    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.

    2000-01-01

    There is an ongoing debate on the technique for central venous catheterization associated with the lowest complication rate and the highest success rate. In an attempt to better define the easiest and safest venous approach, we have reviewed our 7-year experience with 5479 central venous percutaneous punctures (by Seldinger's technique) for the insertion of short-term (n=2109), medium/long-term (n=2627) catheters, as well as double-lumen, large-bore catheters for hemodialysis and/or hemapheresis (n=743). We have analyzed the incidence of the most frequent in-sertion-related complications by comparing seven different venous approaches: jugular vein, low lateral approach; jugular vein, high lateral approach; jugular vein, low axial approach; subclavian vein, infraclavicular approach; subclavian vein, supraclavicular approach; external jugular vein; femoral vein. The results of our retrospective study suggest that the 'low lateral' approach to the internal jugular vein, as described by Jernigan and modified according to our protocol, appears to be the easiest and safest technique for percutaneous insertion of central venous access, being characterized by the lowest incidence of accidental arte-rial puncture (1.2%) and malposition (0.8%), no pneumothorax, and an extremely low rate of repeated attempts (i.e. more than two punctures before successful cannulation) (3.3%). We advocate the 'low lateral' approach to the internal jugular vein as first-choice technique for venipuncture in both adults and children, for both short-term and long-term central venous percutaneous cannulation.

    Arterio-venous fistulas may develop spontaneously, following trauma or infection, or be iatrogenic in nature. We present a rare case of a jejunal arterio- venous fistula in a 35-year-old man with a history of pancreatic head resection that had been performed two years previously because of chronic pancreatitis. The patient was admitted with acute upper abdominal pain, vomiting and an abdominal machinery-type bruit. The diagnosis of a jejunal arterio-venous fistula was established by MR imaging. Transfemoral angiography was performed to assess the possibility of catheter embolization. The angiographic study revealed a small aneurysm of the third jejunal artery, abnormal early filling of dilated jejunal veins and marked filling of the slightly dilated portal vein (13-14 mm). We considered the presence of segmental portal hypertension. The patient was treated with coil embolization in the same angiographic session. This case report demonstrates the importance of auscultation of the abdomen in the initial clinical examination. MR imaging and color Doppler ultrasound are excellent noninvasive tools in establishing the diagnosis. The role of interventional radiological techniques in the treatment of early portal hypertension secondary to jejunal arterio-venous fistula is discussed at a time when this condition is still asymptomatic. A review of the current literature is included.

    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.

  14. Comparison of three peripherally-inserted central catheters: pilot study.

    PubMed

    Di Giacomo, Michele

    Peripherally-inserted central catheters (PICCS) are non-tunnelled, central catheters inserted through a peripheral vein of the arm. They are 50-60 cm long and are usually made of either silicone or second-third generation polyurethane. PICCs can be used for prolonged, continuous or intermittent infusion therapies (up to 3 months) both in hospitalized patients and in patients treated as outpatients, in a hospice, or at home. When establishing a vascular service it is key to select a PICC that meets the requirements of safety, cost-effectiveness, high resistance (ability to take increasing fluid volumes with high pressure devices) and durability, and low complications rate. The complications and dwell times of three different PICCs were studied: coated polyurethane, valved silicone and power-injectable. The study was conducted at the chemotherapy suite at the author's hospital with the aim of selecting the right PICC based on low incidence of complications, resistance and enhanced dwell time. Results show a low incidence of complications and long dwell time among patients with the power-injectable PICC. Furthermore, this study demonstrated a reduction on the rate of occlusion and rupture with power-injectable PICCs, which makes them safer to use for administration of chemotherapy and other vesicant agents, as well as for the management of patients in critical care.

    The upper extremity deep vein thrombosis rate is increasing at the same time that the rate for insertions of peripherally inserted central catheters is on the rise. There is little information on whether the established risk factors for lower extremity deep vein thromboses are effective to predict the occurrence of upper extremity deep vein thrombosis. The purpose of this study was to identify patients at highest risk for upper extremity deep vein thrombosis in order to initiate effective prophylaxis. A retrospective review was undertaken of medical records of all patients with peripherally inserted central catheters inserted in a 6-month period at a Midwestern US hospital. Of the 233 charts reviewed, 17 (7.3%) recorded an upper extremity deep vein thrombosis during the patient's hospital stay. Of the multiple factors identified with deep vein thrombosis in the literature, a weighted risk factor measure, the upper extremity deep vein thrombosis prediction tool, was developed. Sensitivity of the instrument for upper extremity deep vein thrombosis is high (88%), as are its specificity (82%) and negative predictive value (99%), whereas the positive predictive value is low (28%). The total percentage of cases correctly classified is 82%. Further testing is indicated on a larger sample to extend the validity of this instrument.

    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

    Introduction: Prolonged treatment, frequent administration of chemotherapy, antibiotics and blood products in cancer patients requires long term venous access. Central venous catheters (CVC) inserted into the subclavian vein or internal jugular vein, peripherally inserted central venous catheters (PICC) and chemoport (CP) are the commonly used central venous access devices (CVAD). Aim: This study was envisaged to review our experience of CVADs over a one year period and analyze the outcome with regard to catheter life, reasons for removal, complications, patient satisfaction and cost comparison between the CVAD types in the Indian setting. Settings and Design: This was a prospective, observational study carried out in a tertiary care cancer institute. Materials and Methods: 180 CVADs placed in patients with hematological malignancies and solid tumors from January 2014 to December 2014 were included. Statistical Analysis Used: Data was analyzed using descriptive statistics, Mann Whitney U test. P <0.05 was taken as statistically significant. Results: 180 CVADs were placed in 160 patients. The median catheter indwelling period was 76 days (16 days to 313 days) for CVC, 59 days (20days – 313 days) for PICC and 137 days (70 days – 258 days) for CP. 66 out of 160 patients developed complications (41.2%). 108 complication events were noted in 66 patients. There were 40 episodes of CRBSI. Out of the 68 mechanical complications, 37 were encountered during insertion of the CVAD and 31 were during the catheter indwelling period. Out of 160 patients, 138 (86.25%) were satisfied with the CVAD. The cost incurred for CVC/PICC (INR 4,480) was lower than that for CP (INR 24,150) and it was statistically significant (P < 0.0001). Our patients were highly satisfied with the CVAD. Conclusion: Use of CVC and PICC is a safe, reliable and cost saving way of administration of chemotherapy in developing countries. The incidence of complications and catheter loss was acceptable. Our

    Background When managing patients who require repeated venous access, gaining a viable intravenous route has been problematic. To improve the situation, various studies on techniques for venous access have been conducted. The aim of this study is to evaluate the clinical results of complications following totally implanted central venous access port (TICVAP) insertion. Methods A retrospective analysis was conducted on 163 patients, from December 2008 to March 2013. The occurrence of complications was studied in three separate periods of catheter use: the intraoperative period, postoperative period, and period during the treatment. Results A total of 165 cases of TICVAP insertions involving 156 patients were included in the final analysis. There were 35 complications (21%) overall. Among these, 31 cases of complications (19%) occurred during the treatment period and the other 4 cases were intraoperative and postoperative complications (2%). There were no statistically significant differences in age and gender of the patients between the two groups to be risk factors (p=0.147, p=0.08). Past history of chemotherapy, initial laboratory findings, and the locations of TICVAP insertion also showed no statistical significance as risk factors (p>0.05). Conclusion Because the majority of complications occurred after port placement and during treatment, meticulous care and management and appropriate education are necessary when using TICVAPs.

    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

    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. PMID:27397443

    The purpose of this study was to perform an alternative technique for recanalization of a chronic occlusion of the left brachiocephalic vein that could not be traversed with a guidewire. Restoration of a completely thrombosed left brachiocephalic vein was attempted in a 76-year-old male hemodialysis patient with massive upper inflow obstruction, massive edema of the face, neck, shoulder, and arm, and occlusion of the stented right brachiocephalic vein/superior vena cava. Vessel negotiation with several guidewires and multipurpose catheters proved unsuccessful. The procedure was also non-viable using a long, 21G puncture needle. Puncture of the superior vena cava (SVC) at the distal circumference of the stent in the right brachiocephalic vein/superior vena cava, however, was feasible with a transjugular intrahepatic portosystemic shunt (TIPS) set under biplanar fluoroscopy using the distal end of the right brachiocephalic vein as a target, followed by balloon dilatation and partial extraction of thrombotic material of the left brachiocephalic vein with a wire basket. Finally, two overlapping stents were deployed to avoid early re-occlusion. Venography demonstrated complete vessel patency with free contrast media flow via the stents into the SVC, which was reconfirmed in follow-up examinations. Immediate clinical improvement was observed. Venous vascular recanalization of chronic venous occlusion by means of a TIPS needle is feasible as a last resort under certain precautions.

    Central venous catheters (CVCs) are indispensable in modern pediatric medicine. CVCs provide secure vascular access, but are associated with a risk of severe complications, in particular bloodstream infection. We provide a review of the recent literature about the diagnostic and therapeutic challenges of catheter-related bloodstream infection (CRBSI) in children and its prevention. Variations in blood sampling and limitations in blood culturing interfere with accurate and timely diagnosis of CRBSI. Although novel molecular testing methods appear promising in overcoming some of the present diagnostic limitations of conventional blood sampling in children, they still need to solidly prove their accuracy and reliability in clinical practice. Standardized practices of catheter insertion and care remain the cornerstone of CRBSI prevention although their implementation in daily practice may be difficult. Technology such as CVC impregnation or catheter locking with antimicrobial substances has been shown less effective than anticipated. Despite encouraging results in CRBSI prevention among adults, the goal of zero infection in children is still not in range. More high-quality research is needed in the field of prevention, accurate and reliable diagnostic measures and effective treatment of CRBSI in children.

    Central venous catheters (CVCs) account for the largest proportion of thrombotic events in pediatric patients. Questions remain regarding adequate treatment and prevention methods. We surveyed pediatric hematology/oncology specialists, using hypothetical cases to assess management strategies for acute CVC thrombosis and secondary prevention. Survey respondents varied in the use of the thrombophilia evaluation (33.3%, 41/123) and duration of treatment (6 weeks: 54.1%, 66/122). Secondary CVC prophylaxis was utilized by 36.6% (45/123) of respondents and by 24.4% (30/123) but only if there was a documented thrombophilia. This heterogeneity highlights the need for clinical studies to address these important clinical questions.

    A 69-year-old Caucasian man was admitted to our hospital because of myocardial infarction. A central venous catheter (CVC) for infusive therapy was inserted. After two weeks he developed fever, purpura, and knee arthralgia. Hemoculture yielded methicillin-sensitive Staphylococcus aureus. Subsequently, oliguric renal failure, hematuria, and nephrotic range proteinuria were recorded. Renal biopsy showed mesangial proliferation and crescent formation. In an immunofluorescence study, IgA, IgG, and C3 deposition in the mesangium and along arteriolar walls were observed. A diagnosis of Henoch-Schönlein purpura associated with infection caused by CVC was made. After administration of antibiotic and steroid therapy, proteinuria was markedly reduced, renal function improved, and purpura disappeared. The association of HSP with methicillin-resistant Staphylococcus aureus has frequently been reported in the literature. We present here a case of HSP in association with MSSA bacteremia from central venous catheterization, a finding not reported previously.

    To report the efficacy of a new percutaneous technique for extraction of embolized catheters, five female patients (62 ± 14 years) referred to our institution were analyzed. With the combination of a large-diameter steerable sheath with a sizeable snare system, three dislodged Port-A-Cath tubes and two ventriculoatrial shunts were retrieved successfully. Mean procedure time was 51 ± 23 min, biplane fluoroscopy time was 22 ± 21 min, and dose area product was 1188 ± 992 dGy cm(2). Percutaneous extraction of embolized venous catheters is highly effective with the help of this novel, self-assembled system. The presented technique provides major advantages with respect to three-dimensional steerability and should be considered for complex cases.

    Internal jugular veins are the major cerebral venous outflow pathway in supine humans. In upright humans the positioning of these veins above heart level causes them to collapse. An alternative cerebral outflow pathway is the vertebral venous plexus. We set out to determine the effect of posture and central venous pressure (CVP) on the distribution of cerebral outflow over the internal jugular veins and the vertebral plexus, using a mathematical model. Input to the model was a data set of beat-to-beat cerebral blood flow velocity and CVP measurements in 10 healthy subjects, during baseline rest and a Valsalva manoeuvre in the supine and standing position. The model, consisting of 2 jugular veins, each a chain of 10 units containing nonlinear resistances and capacitors, and a vertebral plexus containing a resistance, showed blood flow mainly through the internal jugular veins in the supine position, but mainly through the vertebral plexus in the upright position. A Valsalva manoeuvre while standing completely re-opened the jugular veins. Results of ultrasound imaging of the right internal jugular vein cross-sectional area at the level of the laryngeal prominence in six healthy subjects, before and during a Valsalva manoeuvre in both body positions, correlate highly with model simulation of the jugular cross-sectional area (R2 = 0.97). The results suggest that the cerebral venous flow distribution depends on posture and CVP: in supine humans the internal jugular veins are the primary pathway. The internal jugular veins are collapsed in the standing position and blood is shunted to an alternative venous pathway, but a marked increase in CVP while standing completely re-opens the jugular veins.

    Peripherally inserted central catheters (PICCs) continue to be necessary in neonatal care. They benefit many premature infants and those needing long-term intravenous access. An experienced inserter, early recognition of PICC candidates, early PICC placement, knowledge of anatomy, and correct choice of vein all increase placement success. As with any invasive procedure, there are risks. These include pain, difficulty advancing the catheter, damage to vessels, catheter malposition, and bleeding. Utilizing assessment skills, following the product manufacturer's instructions, and carefully placing the catheter should minimize most of these risks. Additional risks include postinsertion complications such as occlusions, thrombosis, catheter failure, infection, and catheter malposition. Proper nursing care--which includes controlling infection, properly securing the catheter, and changing the dressing as needed--is key to preventing complications and maintaining the PICC until treatment has been completed.

    Nek2 (NIMA-related kinase 2) is a serine-threonine kinase and human homolog of the mitotic regulator NIMA of Aspergillus nidulan. We reported the efficiency of Nek2 siRNA in several cancer xenograft models using cholangiocarcinoma, breast cancer and colorectal cancer. Pancreatic cancer is difficult to treat due to its rapid progression and resistance to chemotherapy. Novel treatments are urgently required to improve survival in pancreatic cancer, and siRNA are a promising therapeutic option. However, finding an in vivo drug delivery system of siRNA remains a major problem for clinical application. In this study, the overexpression of Nek2 was identified in pancreatic cancer cell lines. Nek2 siRNA inhibited tumor growth in a subcutaneous xenograft mouse model of pancreatic cancer, prolonged the survival time in an intraperitoneal xenograft mouse model and efficiently prevented the progression of liver metastasis using a portal venous port-catheter system. Taken together, Nek2 is an effective therapeutic target in pancreatic cancer. An adequate delivery system is considered important in treating advanced pancreatic cancer, such as peritoneal dissemination and liver metastasis. Further investigations are required on the safety and side effects of the portal venous port-catheter system. We hope that Nek2 siRNA will be a novel therapeutic strategy for pancreatic cancer with liver metastasis and peritoneal dissemination.

    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.

    Umbilical venous catheters allow rapid central access in neonates, but may be associated with various complications. We present a case of a newborn with pericardial effusion following umbilical venous catheterization. An extremely low birth weight infant was intubated for respiratory distress syndrome and had umbilical venous and arterial lines in place. Massive cardiomegaly was noted on the subsequent chest X-ray. Echocardiography revealed a large pericardial effusion without signs of tamponade. After removing the catheter, the effusion gradually resolved. While pericardial effusion is a well-known complication of percutaneous long central lines, only a few case reports have documented sudden cardiovascular compromise associated with umbilical venous catheters. Pericardial effusion may be asymptomatic and should be suspected in infants with central catheters and progressive cardiomegaly. The prompt removal of catheters and, if signs of cardiac tamponade are present, emergency pericardiocentesis may prove to be life-saving.

    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.

    Background: This study was performed to evaluate the learning curve and related complications of ultrasound (US) guided central venous catheter (CVC) insertion in infants. Materials and Methods: This study was performed in Imam Hosein Hospital of Isfahan from September 2014 to March 2015. Participants were infants consecutively candidate for CVC insertion. Three steps were designed to complement the learning. For each step of learning, 20 patients were considered and for every patient one CVC was inserted: (1) In the first step, venous puncture and guide wire passage was performed by an experienced radiologist and the surgeon was taught how to do it, then CVC was placed by the surgeon. (2) In the second step, venous puncture and guide-wire passage was performed by the surgeon under the supervision of the same radiologist, and then CVC was placed by the surgeon. (3) In the third step, US-guided CVC insertion was performed by the surgeon completely, and the radiologist came to the operating room only if it was necessary. In each of these steps, the time spent of the US probe on the skin until the guide wire passage into the vein was recorded for every patient. All perioperative complications were recorded. Results: The mean point for the time spent of the US probe on the skin until the guide wire passage into the vein was 84.9 ± 13.6, 119.1 ± 15.2, and 90.3 ± 11.2 s in the step 1, 2 and 3, respectively (P = 0.04). There was no significant difference between the frequencies of complications among tree steps. Conclusion: US-guided percutaneous CVC insertion is a safe and reliable method which can be easily and rapidly learned. PMID:26601087

    Introduction Paediatric central venous access devices (CVADs) are associated with a 25% incidence of failure. Securement and dressing are strategies used to reduce failure and complication; however, innovative technologies have not been evaluated for their effectiveness across device types. The primary aim of this research is to evaluate the feasibility of launching a full-scale randomised controlled efficacy trial across three CVAD types regarding CVAD securement and dressing, using predefined feasibility criteria. Methods and analysis Three feasibility randomised, controlled trials are to be undertaken at the Royal Children's Hospital and the Lady Cilento Children's Hospital, Brisbane, Australia. CVAD securement and dressing interventions under examination compare current practice with sutureless securement devices, integrated securement dressings and tissue adhesive. In total, 328 paediatric patients requiring a peripherally inserted central catheter (n=100); non-tunnelled CVAD (n=180) and tunnelled CVAD (n=48) to be inserted will be recruited and randomly allocated to CVAD securement and dressing products. Primary outcomes will be study feasibility measured by eligibility, recruitment, retention, attrition, missing data, parent/staff satisfaction and effect size. CVAD failure and complication (catheter-associated bloodstream infection, local infection, venous thrombosis, occlusion, dislodgement and breakage) will be compared between groups. Ethics and dissemination Ethical approval to conduct the research has been obtained. All dissemination will be undertaken using the CONSORT Statement recommendations. Additionally, the results will be sent to the relevant organisations which lead CVAD focused clinical practice guidelines development.

  16. Intraluminal Release of an Antifungal β-Peptide Enhances the Antifungal and Anti-Biofilm Activities of Multilayer-Coated Catheters in a Rat Model of Venous Catheter Infection

    PubMed Central

    2015-01-01

    Candida albicans is the most prevalent cause of hospital-acquired fungal infections and forms biofilms on indwelling medical devices that are notoriously difficult to treat or remove. We recently demonstrated that the colonization of C. albicans on the surfaces of catheter tube segments can be reduced in vitro by coating them with polyelectrolyte multilayers (PEMs) that release a potent antifungal β-peptide. Here, we report on the impact of polymer structure and film composition on both the inherent and β-peptide-mediated ability of PEM-coated catheters to prevent or reduce the formation of C. albicans biofilms in vitro and in vivo using a rat model of central venous catheter infection. Coatings fabricated using polysaccharide-based components [hyaluronic acid (HA) and chitosan (CH)] and coatings fabricated using polypeptide-based components [poly-l-lysine (PLL) and poly-l-glutamic acid (PGA)] both served as reservoirs for the loading and sustained release of β-peptide, but differed substantially in loading and release profiles and in their inherent antifungal properties (e.g., the ability to prevent colonization and biofilm growth in the absence of β-peptide). In particular, CH/HA films exhibited inherent antifungal and antibiofilm behaviors in vitro and in vivo, a result we attribute to the incorporation of CH, a weak polycation demonstrated to exhibit antimicrobial properties in other contexts. The antifungal properties of both types of films were improved substantially when β-peptide was incorporated. Catheter segments coated with β-peptide-loaded CH/HA and PLL/PGA films were both strongly antifungal against planktonic C. albicans and the formation of surface-associated biofilms in vitro and in vivo. Our results demonstrate that PEM coatings provide a useful platform for the design of new antifungal materials, and suggest opportunities to design multifunctional or dual-action platforms to prevent or reduce the severity of fungal infections in applied

    Objectives The objective of this exploratory study was to find out the correlation of femoral vein diameter (FVD) to central venous pressure (CVP) measurements and to derive a prediction equation to help ascertain the fluid volume status in a critical patient. Patients and methods This was a single-centered prospective cohort study designed and conducted by the critical care department of Shifa International hospital in Islamabad, Pakistan. Patients were enrolled from the medical and surgical intensive care units. The inclusion criteria consisted of patients > 18 years of age, and an intrathoracic central venous catheterization (CVC) in place for producing CVP waveform through the transducer. Patients having contraindications to CVP placement and those unable to lie supine were excluded from the study. Critical Care fellows with sufficient training in performing venous ultrasonography measured the FVD. They were blinded to the CVP values of the same patients. Results The study included 108 patients. Among these 70/108 (64.8%) were males. Mean age was 53.85 (SD=16.74). The CVP and femoral vein diameter were measured in all patients. Mean CVP was 9.89 cmH2O (SD=3.46) and mean femoral vein diameter was 0.92 cm (SD=0.27). Multiple regression was used to generate a prediction model. FVD, age and sex of the patient were used as predictor variables to predict CVP diameter. The model was statistically significant with a p-value of < 0.000 and an F-value of 104.806. R-squared value for this model came out to be 0.744, thus the model was able to explain about 74.4% of the variance in the values observed for CVP. When controlled for age and sex, FVD was found highly correlated with CVP diameter with a p-value of < 0.000. A regression equation was derived that can be used to generate predicted values of CVP in millimeters of mercury with an R-square of 0.745 if FVD in centimeters is provided; CVP (cmH2O) = -0.039 + 10.718* FVD. Conclusions FVD was found highly correlated to

    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.

    Infusion therapy is often viewed as a means to an end - a way to administer medications and fluids. It is one of the few specialties that affect almost all areas of healthcare. Safe, effective and reliable vascular access should be the goal of every health professional who is starting a patient on a prescribed course of intravenous therapy, especially if that patient is undergoing a prolonged course. This article aims to refresh and update nurses' clinical knowledge of the detailed patient assessment required before choosing a central venous access device, as well as supporting a reduction in complications and earlier recognition of potential problems. It discusses clinical indications for devices, the range of long-term intravenous therapies that can be used, and patient assessment.

    Peripheral intravenous (PIV) infiltrations causing tissue damage is a global issue surrounded by situations that make vascular access decisions difficult. The purpose of this quality improvement project was to develop an algorithm and assess its effectiveness in reducing PIV infiltrations in neonates. The targeted subjects were all infants in our neonatal intensive care unit (NICU) with a PIV catheter. We completed a retrospective chart review of the electronic medical record to collect 4th quarter 2012 baseline data. Following adoption of the algorithm, we also performed a daily manual count of all PIV catheters in the 1st and 2nd quarters 2013. Daily PIV days were defined as follows: 1 patient with a PIV catheter equals 1 PIV day. An infant with 2 PIV catheters in place was counted as 2 PIV days. Our rate of infiltration or tissue damage was determined by counting the number of events and dividing by the number of PIV days. The rate of infiltration or tissue damage was reported as the number of events per 100 PIV days. The number of infiltrations and PIV catheters was collected from the electronic medical record and also verified manually by daily assessment after adoption of the algorithm. To reduce the rate of PIV infiltrations leading to grade 4 infiltration and tissue damage by at least 30% in the NICU population. Incidence of PIV infiltrations/100 catheter days. The baseline rate for total infiltrations increased slightly from 5.4 to 5.68/100 PIV days (P = .397) for the NICU. We attributed this increase to heightened awareness and better reporting. Grade 4 infiltrations decreased from 2.8 to 0.83/100 PIV catheter days (P = .00021) after the algorithm was implemented. Tissue damage also decreased from 0.68 to 0.3/100 PIV days (P = .11). Statistical analysis used the Fisher exact test and reported as statistically significant at P < .05. Our findings suggest that utilization of our standardized decision pathway was instrumental in providing guidance for

In this case, percutaneous interventional radiological procedures (balloon angioplasty and snare loop method) in conjunction with medical treatment were effective in limiting the post-thrombotic syndrome and restoring the proper positioning of the catheter, thereby saving the central venous access.

    We retrospectively analyzed our 2-year experience with venous access for 363 therapeutic plasma exchanges in 46 patients with neurological disease, including acute Guillain-Barré syndrome (N = 20), myasthenia gravis (N = 17), and chronic inflammatory demyelinating polyneuropathy (N = 9). Twenty-three patients (50%) completed the planned course of therapy using only peripheral venous access, and 28 central venous catheters were placed in the remaining 23 patients. Patients utilizing central venous access did not undergo a greater number of procedures, but they were more likely to have acute Guillain-Barré syndrome (P < 0.02) or to be hospitalized in a medical intensive care unit (P < 0.01). Three types of central catheters were used, and although our experience was predominantly with 1 type, differences were noted. Only 3% of procedures (3 of 96) done with a Quinton-Mahurkar catheter were associated with a catheter failure, compared to 27% (4 of 15, P < 0.01) with a Hickman catheter and 67% (2 of 3) with a triple-lumen catheter. Life-threatening complications occurred with 3 of 28 (11%) central catheters. To optimize the success of therapeutic plasma exchange using central access, it is critical that hemapheresis personnel advise each patient's primary physician regarding the type of central venous catheter required. Currently, we recommend use of a Quinton-Mahurkar or other dual-lumen hemodialysis catheter.

    Background and purpose.In percutaneous placement of central venous catheters an inadvertent, direct lesion of the lung parenchyma can occur. This is a cause of iatrogenic pneumothorax, whose incidence is approximately 1 to 4%, largely dependent on the experience of the operator, the site of venipuncture and proba-bly the technique employed. Initial treatment currently ranges from observation alone to formal tube-thoracostomy. In an attempt to define the best initial treatment, if any, we reviewed our personal series and contributions from the literature. As a result we have produced a flow-chart proposing a rational treatment of this frequent complication. Patients and Methods.One thousand four hundred twenty-one ports were placed in patients at the Department of Surgery of the European Institute of Oncology in Milan through an infraclavicular standardized percutaneous subclavian approach. They were placed during the 60-month period from January 1, 1996 to December 31, 2000 for long-term chemotherapy treatment of solid tumours. Chest upright X-rays were obtained post-operatively in all cases to check the correct position of the catheter tip and the presence of pneumothorax. Results.Twenty-two patients out of 1421 (1.54%) experienced a radiologically-proven pneumothorax, ranging from 5 to 70% of the affected pleural space. Sixteen patients out of 22 (72.7%) with minor portions of affected pleural space received simple observation. In these patients the most common finding was an uncomplicated tachycardia (more than 100 beats/min); 8 of them did not complain of any symptoms. Six patients (27.2%) un-derwent an additional procedure (3 tube-thoracostomies and 3 aspirations of the pleural space), claiming symptoms of chest pain and various degrees of dyspnea. Tube thoracostomy was mainly adopted at the beginning of our experience, and in patients with a severe degree of pleural involvement (55 to 70% of the pleural space). Aspiration, instead, was used more recently and

    The study aimed to analyze the history of the use of the peripherally inserted central catheters in adult patients admitted to hospital from 2000 to 2007. The historical cohort approach was used with retrospective data collection from medical records of the Catheter Group of the Moinhos de Vento Hospital Association in Porto Alegre, RS, totaling 229 catheters inserted. The growth curve in the use of the PICC was from 1 catheter inserted in 2000 to 57 in 2007. The most prevalent pathology was oncology (17.9%, n=41). In relation to the indications of use, antibiotic use prevailed (54.1%, n=124). In the radiological confirmation the vena cava was prevalent (68.1%, n=156). The use of the PICC in the hospital environment is expanding and nursing has a fundamental role in its insertion, maintenance and removal.

    Introduction Peripheral venous catheters (PVC) are medical devices most frequently used during hospital care. Although the frequency of specific PVC-related adverse events (PVCAEs) has been reported, the global risk related to the insertion of this device is poorly estimated. The aim of this study is to determine the incidence of PVCAEs during the indwell time, after catheter removal, and to identify practice-mirroring risk factors. Methods A prospective observational study was conducted as a part of a research project, called CATHEVAL, in one surgery ward and four medicine wards from three public general tertiary care hospitals in Northern France that were invited to participate between June-2013 and June-2014. Each participating ward included during a two-month study period all patients older than 15 years carrying a PVC. All inserted PVCs were monitored from insertion of PVC to up to 48 hours after removal. Monitored data included several practice-mirroring items, as well as the occurrence of at least one PVCAE. A multivariate Cox proportional hazard model, based on a marginal risk approach, was used to identify factors associated with the occurrence of at least one PVCAE. Results Data were analysed for 815 PVCs (1964 PVC-days) in 573 patients. The incidence of PVCAE was 52.3/100 PVCs (21.9/100 PVC-days). PVCAEs were mainly clinical: phlebitis (20.1/100 PVCs), haematoma (17.7/100 PVCs) and liquid/blood escape (13.1/100 PVCs). Infections accounted for only 0.4/100 PVCs. The most frequent mechanical PVCAEs, was obstruction/occlusion of PVC (12.4/100 PVCs). The incidence of post-removal PVCAEs was 21.7/100 PVCs. Unstable PVC and unclean dressing were the two main risk factors. Conclusion Limitation of breaches in healthcare quality including post-removal monitoring should be reinforced to prevent PVC-related adverse events in hospital settings. PMID:28045921

    The arterial and mixed venous carbon dioxide tension gradient has been shown to increase when there is a decrease in cardiac output. Monitoring central venous gases is an attractive alternative to monitoring mixed venous gases in circulatory failure because central venous catheterisation is a less invasive procedure than pulmonary artery catheterisation. This study aims to evaluate the agreement between central venous-arterial carbon dioxide (CVA-CO2) and mixed venous-arterial carbon dioxide (SVA-CO2) tension gradients and assess whether CVA-CO2 tension gradient can be used to predict cardiac output in circulatory failure. Samples of arterial, central venous and mixed venous blood were obtained from 16 patients with circulatory failure at different inspired oxygen concentrations and cardiac indexes within 24 hours of study enrolment. CVA-CO2 and SVA-CO2 tension gradient were not interchangeable numerically (bias = 0.14 mmHg, 95% limits of agreement: -3.0 to 3.2 mmHg). CVA-CO2 (Spearman correlation coefficient r = -0.385) and SVA-CO, (r = -0.578) tension gradient were significantly correlated with the cardiac index but the cardiac index only accounted for 21% and 32% of the variability of CVA-CO, and SVA-CO2 tension gradient, respectively. The ability of CVA-CO2 tension gradient (area under the ROC curve = 0.77, 95% confidence interval [CI]: 0.49-0.99; P = 0.08) to predict a low cardiac output state (cardiac index < 2.5 l/min/m2) was lower than SVA-CO2 (area under the ROC curve = 0.95, 95% CI: 0.88-0.99; P = 0.003). The utility of CVA-CO2 and SVA-CO2 tension gradient appeared to be limited to their negative predictive value to exclude a low cardiac output state when CVA-CO, or SVA-CO, tension gradient was normal (< or =5 mmHg).

    Sutureless catheter securement systems are intended to eliminate risks associated with sutures. The clinical acceptability of a novel system was investigated compared with the current method of securement for peripherally inserted central catheters (19 facilities using StatLock or sutures) or nontunneled central vascular access devices (3 facilities using StatLock or sutures or HubGuard + Sorbaview Shield). More than 94% of respondents rated the novel system as same, better, or much better than their current product. More than 82% of respondents were willing to replace their current system with the new one. PMID:27379679

    Most hospitalized patients have placement of a peripheral venous access device, either a short peripheral catheter or a peripherally inserted central catheter. Compared with central venous catheters that are not peripherally inserted, the other 2 types are generally perceived by health care providers as safer and less complicated to manage, and less emphasis is placed on the prevention and management of complications. Expertise of nurses in inserting, managing, and removing these devices may reduce the likelihood of complications, and increased recognition of complications associated with use of the devices is important to ensure continued improvements in the safety, quality, and efficiency of health care. Complications associated with short peripheral catheters and peripherally inserted central catheters include tourniquet retention, tubing and catheter misconnections, phlebitis, air embolism, device fragment embolization, and inadvertent discharge with a retained peripheral venous access device. Integration of prevention, detection, and recovery strategies into personal nursing practice promotes the quality and safety of health care delivery.

    In the early phase of the Space Shuttle program, NASA flight surgeons implemented a fluid-loading countermeasure in which astronauts were instructed to ingest eight 1-g salt tablets with 960 ml of water approximately 2 hours prior to reentry from space. This fluid loading regimen was intended to enhance orthostatic tolerance by replacing circulating plasma volume reduced during the space mission. Unfortunately, fluid loading failed to replace plasma volume in groundbased experiments and has proven minimally effective as a countermeasure against post-spaceflight orthostatic intolerance. In addition to the reduction of plasma volume, central venous pressure (CVP) is reduced during exposure to actual and groundbased analogs of microgravity. In the present study, we hypothesized that the reduction in CVP due to exposure to microgravity represents a resetting of the CVP operating point to a lower threshold. A lower CVP 'setpoint' might explain the failure of fluid loading to restore plasma volume. In order to test this hypothesis, we conducted an investigation in which we administered an acute volume load (stimulus) and measured responses in CVP, plasma volume and renal functions. If our hypothesis is true, we would expect the elevation in CVP induced by saline infusion to return to its pre-infusion levels in both HDT and upright control conditions despite lower vascular volume during HDT. In contrast to previous experiments, our approach is novel in that it provides information on alterations in CVP and vascular volume during HDT that are necessary for interpretation of the proposed CVP operating point resetting hypothesis.

  13. Principles of tunneled cuffed catheter placement.

    2011-12-01

    Tunneled cuffed catheters provide reliable and instant long-term intravenous access for a large variety of therapeutic purposes, including chemotherapy, parenteral nutrition, and apheresis. The most frequent application is for patients with renal failure as an access device for hemodialysis. In this capacity, the rate of catheter use has remained stable in the United States, despite the promotion of arteriovenous fistulas and arteriovenous grafts. The latter 2 procedures achieve superior longevity and much higher cost-efficiency. Tunneled catheters, however, serve as bridging devices during maturation of newly placed arteriovenous fistulas or as the final option in patients in whom fistulas and grafts have failed. High-quality vascular access is a hallmark of interventional radiology, and its significance for patient care and for our specialty cannot be overestimated. Familiarity with basic concepts of the device and procedural techniques are crucial to achieve successful long-term venous access. The following article demonstrates key concepts of tunneled venous catheter placement by means of dialysis, inasmuch as dialysis catheters represent the most commonly placed tunneled central venous catheters. The principles of placement and techniques utilized, however, are applicable to devices that are used for chemotherapy or parenteral nutrition, such as the Hickman, Broviac, Groshong, or tunneled peripherally inserted central catheters.

    Central venous catheterisation allows delivery of medications, intravenous fluids, parenteral nutrition, haemodialysis and monitoring of haemodynamic variables. Various complications may occur during and after the procedure. However, the complete guidewire retention has rarely been reported. In this report, we have presented a complete guidewire retention as a result of inadvertent catheter insertion. After 17 months of the first operation performed upon the diagnosis of Fournier's gangrene, the patient was admitted to the cardiology polyclinic with a recurrent chest pain. Echocardiography showed a wire-shaped foreign body within the right part of the heart, and a fluoroscopic examination showed a guidewire reaching from the superior vena cava to the right external iliac vein. In retrospect, the wire was already visible on the postoperative chest x-rays and CT taken while the patient was still in intensive care unit, but its presence was overlooked at that time. The guidewire was retrieved completely during a surgery.

    Measurements were made of sinus node responses to arterial baroreceptor stimulation with phenylephrine injection or neck suction, before and during changes of central venous pressure provoked by lower body negative pressure or leg and lower truck elevation. Variations of central venous pressure between 1.1 and 9.0 mm Hg did not influence arterial baroreflex mediated bradycardia. Baroreflex sinus node responses were augmented by intravenous propranolol, but the level of responses after propranolol was comparable during the control state, lower body negative pressure, and leg and trunk elevation. Sinus node responses to very brief baroreceptor stimuli applied during the transitions of central venous pressure also were comparable in the three states. The authors conclude that physiological variations of central venous pressure do not influence sinus node responses to arterial baroreceptor stimulation in man.

    The purpose of this study was to assess the technical success rate and adverse events (AEs) associated with ultrasound (US)-guided radiological placement (RP) of a central venous port (CVP) via the subclavian vein (SCV). Between April 2006 and May 2007, a total of 500 US-guided RPs of a CVP via the SCV were scheduled in 486 cancer patients (mean age +/- SD, 54.1 +/- 18.1 years) at our institute. Referring to the interventional radiology report database and patients' records, technical success rate and AEs relevant to CVP placement were evaluated retrospectively. The technical success rate was 98.6% (493/500). AEs occurred in 26 cases (5.2%) during follow-up (range, 1-1080 days; mean +/- SD, 304.0 +/- 292.1 days). AEs within 24 h postprocedure occurred in five patients: pneumothorax (n = 2), arterial puncture (n = 1), hematoma formation at the pocket site (n = 2), and catheter tip migration into the internal mammary vein (n = 1). There were seven early AEs: hematoma formation at the pocket site (n = 2), fibrin sheath formation around the indwelling catheter (n = 2), and catheter-related infections (n = 3). There were 13 delayed AEs: catheter-related infections (n = 7), catheter detachments (n = 3), catheter occlusion (n = 1), symptomatic thrombus in the SCV (n = 1), and catheter migration (n = 1). No major AEs, such as procedure-related death, air embolism, or events requiring surgical intervention, were observed. In conclusion, US-guided RP of a CVP via the SCV is highly appropriate, based on its high technical success rate and the limited number of AEs.

    2017-01-01

    Background With the increasing frequency of tunneled hemodialysis catheter use there is a parallel increase in the need for removal and/or exchange. A small but significant minority of catheters become embedded or ‘stuck’ and cannot be removed by traditional means. Management of embedded catheters involves cutting the catheter, burying the retained fragment with a subsequent increased risk of infections and thrombosis. Endoluminal dilatation may provide a potential safe and effective technique for removing embedded catheters, however, to date, there is a paucity of data. Objectives 1) To determine factors associated with catheters becoming embedded and 2) to determine outcomes associated with endoluminal dilatation Methods All patients with endoluminal dilatation for embedded catheters at our institution since Jan. 2010 were included. Patients who had an embedded catheter were matched 1:3 with patients with uncomplicated catheter removal. Baseline patient and catheter characteristics were compared. Outcomes included procedural success and procedure-related infection. Logistic regression models were used to determine factors associated with embedded catheters. Results We matched 15 cases of embedded tunneled catheters with 45 controls. Among patients with embedded catheters, there were no complications with endoluminal dilatation. Factors independently associated with embedded catheters included catheter dwell time (> 2 years) and history of central venous stenosis. Conclusion Embedded catheters can be successfully managed by endoluminal dilatation with minimal complications and factors associated with embedding include dwell times > 2 years and/or with a history of central venous stenosis.

    In the last decade new central venous access devices (CVADs) inserted for long-term therapy have replaced conventional peripheral venous access devices. This shift contributes to the need for additional education as technological advances result in additional options for central venous access. Healthcare's transition from the hospital to a community-based system has increased the use of CVADs in the home setting. Issues that confront the patient with a CVAD in the home setting must be examined more closely than ever before.

    Tunneled lower extremity peripherally inserted central catheters (PICCs) are placed in infants under combined ultrasound and fluoroscopic guidance in the interventional radiology suite. In infants requiring a bedside procedure, image guidance is limited, often using portable radiographs during the procedure. This report demonstrates feasibility of placing tunneled lower extremity PICCs using ultrasound as the sole imaging modality for vascular access, intravascular length measurement, and final confirmation of catheter tip position in a case series of 15 critically ill infants. The technique negates the need for added imaging confirmation methods that use ionizing radiation and can be performed at the bedside.

    Minimally invasive percutaneous interventions are often used for enteral nutrition, biliary and urinary diversion, intra-abdominal fluid collection drainage, and central venous access. In most cases, radiologic and endoscopic placement of catheters and tubes has replaced the comparable surgical alternative. As experience with catheters and tubes grows, it becomes increasingly evident that the interventional radiologist needs to be an expert not only on device placement but also on device management. Tube dysfunction represents the most common complication requiring repeat intervention, which can be distressing for patients and other health care professionals. This manuscript addresses the etiologies and solutions to leaking and obstructed feeding tubes, percutaneous biliary drains, percutaneous catheter nephrostomies, and drainage catheters, including abscess drains. In addition, we will address the obstructed central venous catheter. PMID:26038615

    Central venous catheterization is a commonly used and important intervention. Despite its regular use it is still associated with a high incidence of complications especially infection and catheter tip embolization. Addition of ultrasound guidance to the technique has shown great improvement to the time and number of attempts for successful catheterization. The preference of vein depends greatly on the situation; subclavian vein is the preferred method overall but internal jugular vein is preferred in patients undergoing cardiac or thoracic surgery. This is especially true for pediatric patients in whom femoral vein catheterization is still preferred despite it carrying a higher risk than other locales. Addition of ultrasound guidance greatly reduces the incidence of arterial puncture and subsequent hematoma formation regardless of location. This is because it allows for visualization of anatomical variation prior to intervention and continual visualization of the needle during the placement. It is noteworthy however, that addition of ultrasound does not prevent complications such as catheter tip embolization as this may occur even with perfect placement. The value of ultrasound usage is undisputable since all studies assessing the difference between it and landmark based methods showed preferable outcome.

    The aim of this study was to determine, in a population with metastatic breast cancer treated with bevacizumab therapy, the incidence of wound dehiscence after placement of an implantable venous access device (VAD) and to study the risk of catheter thrombosis. This study enrolled all VADs placed by 14 anesthetists between 1 January 2007 and 31 December 2009: 273 VADs in patients treated with bevacizumab therapy and 4196 VADs in patients not treated with bevacizumab therapy. In the bevacizumab therapy group, 13 cases of wound dehiscence occurred in 12 patients requiring removal of the VAD (4.76%). All cases of dehiscence occurred when bevacizumab therapy was initiated less than 7 days after VAD placement. Bevacizumab therapy was initiated less than 7 days after VAD placement in 150 cases (13 of 150: 8.6%). The risk of dehiscence was the same from 0 to 7 days. In parallel, the VAD wound dehiscence rate in patients not receiving bevacizumab therapy was eight of 4197 cases (0.19%) (Fisher's test significant, P<0.001). No risk factors of dehiscence were identified: anesthetists, learning curves, and irradiated patients. VAD thrombosis occurred in four patients (1.5%). In parallel, VAD thrombosis occurred in 51 of 4197 patients (1.2%) not receiving bevacizumab therapy (Fisher's test not significant; P=0.43). Bevacizumab therapy was permanently discontinued in five patients related to wound dehiscence and in one patient due to extensive skin necrosis. These data suggest the need to observe an interval of at least 7 days between VAD placement and initiation of bevacizumab therapy to avoid the risk of a wound dehiscence requiring chest wall port explant. The risk of VAD thrombosis does not require any particular primary prevention.

    Central venous catheterization as a frequent routine clinical procedure may have significant complications. Mechanical complications may occur during catheter placement, whereas thromboembolic and infectious complications can be seen during follow-up. Total parenteral nutrition (TPN) associated central venous catheterizations may result in early mechanical complications and thrombotic and infectious complications in the long term. This paper describes a patient diagnosed as mitochondrial neurogastrointestinal encephalomyopathy requiring long-term central venous catheterization for TPN implementation, who had an infected thrombus on the catheter tip resected by cardiac surgery.

    Central venous catheters are commonly used in critically ill patients. Such catheterization may entail mechanical and infectious complications. The interest in catheter-related infection lies in the morbidity, mortality and costs that it involved. Numerous contributions have been made in the prevention of catheter-related infection and the current review focuses on the possible current role of antimicrobial impregnated catheters to reduce catheter-related bloodstream infections (CRBSI). There is evidence that the use of chlorhexidine-silver sulfadiazine (CHSS), rifampicin-minocycline, or rifampicin-miconazol impregnated catheters reduce the incidence of CRBSI and costs. In addition, there are some clinical circumstances associated with higher risk of CRBSI, such as the venous catheter access and the presence of tracheostomy. Current guidelines for the prevention of CRBSI recommended the use of a CHSS or rifampicin-minocycline impregnated catheter in patients whose catheter is expected to remain in place > 5 d and if the CRBSI rate has not decreased after implementation of a comprehensive strategy to reduce it.

    Central venous catheterization is commonly performed in clinical practice. Traditional procedural technique is based on anatomical landmarks, but is associated with a high risk of failure and complications. To decrease their incidence European and American societies recommend application of ultrasonography. Preliminary ultrasonographic examination allows for assessment of local anatomical relations as well as vessel morphology (diameter, patency), while real-time ultrasonography increases chances of successful needle insertion. This paper presents the most common venous access sites and procedure techniques.

    Abstract A prospective randomized, controlled, single-blinded trial to compare the effectiveness and safety of heparin saline (HS) to those of normal saline (NS) as flushing and locking solutions for peripheral venous catheter (PVC) in decompensated liver cirrhosis (DLC) patients. Patients with DLC at our institution between April 2012 and March 2013 were enrolled after obtaining informed consent. The patients were randomly allocated into 2 groups: the NS group received preservative-free 0.9% sodium chloride as the flushing and locking solution, while the HS group received HS (50 U/mL). PVC-related events and the duration of PVC maintenance were compared between the 2 groups. Moreover, the preinfusion and postinfusion levels of prothrombin time (PT), activated partial thromboplastin time (APTT), and platelet (PLT) were also compared. A total of 32 and 36 DLC patients in the NS (125 PVCs) and HS (65 PVCs) groups, respectively, were analyzed. Baseline characteristics, including gender, age, Child–Pugh grade, PVC type and administration of anticoagulant, and irritant agents, were comparable between the 2 groups (P > 0.05). The maintenance times of the HS and NS groups were 80.27 ± 26.47 and 84.19 ± 29.32 hours, respectively (P = 0.397). Removal of PVC for abnormal reasons occurred in 30.7% and 22.4% of patients in the HS and NS groups (P = 0.208). The PVC occlusion rates were 6.2% and 5.6% in the HS and NS groups, respectively (OR = 1.11, 95% CI 0.31–3.92). The PT, APTT, and PLT levels were comparable between the 2 groups both before and after infusion (P > 0.05). Incremental analyses showed that Child–Pugh grade C might be a risk factor for the suppression of PLT in the HS group. We consider NS to be as effective as and safer than conventional HS for flushing and locking PVC in decompensated liver cirrhosis patients. PMID:26252305

    Central venous catheterization is usually done in operating theater after general anesthesia. However, life-threatening complications can occasionally occur. Recently, application of ultrasound especially ultrasound-guided venipuncture has become popular for safe and reliable procedure. We investigated the current state of central venous catheterization by a questionnaire survey. 131 anesthesiologists answered the survey. The most common site for cathererization was internal jugular vein (85%). 97% of anesthesiologists use Seldinger's technique. Before internal jugular vein cathererization, 47% of anesthesiologists commonly and 19% of anethesiologists occasionally use ultrasound for checking the vein. Ultrasound-guided venipuncture was performed commonly by 19% and occasionally by 59% of anesthesiologists. The most common ultrasound device was iLook (37% of anesthesiologists, Japan Sherwood). The survey showed that 79% of anesthesiologists apply ultrasound for central venous catheterization in the operating theater. Establishing the standard technique and training methods will be the subsequent issue.

    Central venous catheter-related infections have been associated with high morbidity, mortality, and costs. Catheter use in chronic hemodialysis patients has been recognized as distinct from other patient populations who require central venous access, leading to recent adaptations in guidelines-recommended diagnosis for catheter-related bacteremia (CRB). This review will discuss the epidemiology and pathogenesis of hemodialysis CRB, in addition to a focus on interventions that have favorably affected CRB outcomes. These include: (1) the use of prophylactic topical antimicrobial ointments at the catheter exit site, (2) the use of prophylactic catheter locking solutions for the prevention of CRB, (3) strategies for management of the catheter in CRB, and (4) the use of vascular access managers and quality initiative programs.

    2008-09-01

    Suitable central venous access for hemodialysis is frequently required in patients with end-stage renal disease, whenever an arteriovenous fistula or peritoneal dialysis fails or is not a possibility. Ultimately, long-term dialysis via central access may result in dysfunctional catheter with problems such as malpositioning of catheter tip, fibrin sheath formation, thrombosis, infection, and bleeding. The role of interventional radiology is to deliver appropriate treatment to maintain patent and functional access, while minimizing the risk of venous occlusive disease. This article aims at describing different techniques and approaches for management of fibrin sheath associated with malfunctioning tunneled dialysis catheters, as well as to provide scientific evidence from the current literature.

    Objective In acute respiratory distress syndrome (ARDS), conservative fluid management increases ventilator-free days without affecting mortality. Response to fluid management may differ based on patients’ initial central venous pressure (CVP). We hypothesized initial CVP would modify the effect of fluid management on outcomes. Design Retrospective analysis of the Fluid and Catheter Treatment Trial, a multicenter randomized trial comparing conservative to liberal fluid management in ARDS. We examined the relationship between initial CVP, fluid strategy, and 60-day mortality in univariate and multivariable analysis. Setting Twenty acute care hospitals. Patients Nine hundred and thirty-four ventilated ARDS patients with a CVP available at enrollment, 609 without baseline shock (for whom fluid balance was managed by study protocol). Interventions None. Measurements and Main Results Among patients without baseline shock, those with initial CVP > 8 mmHg experienced similar mortality with conservative and liberal fluid management (18% versus 18%, p=0.928), whereas those with CVP ≤8 mmHg experienced lower mortality with a conservative strategy (17% versus 36%, p=0.005). Multivariable analysis demonstrated an interaction between initial CVP and the effect of fluid strategy on mortality (p=0.031). At higher initial CVPs, the difference in treatment between arms was predominantly furosemide administration, which was not associated with mortality (p=0.122). At lower initial CVPs, the difference between arms was predominantly fluid administration, with additional fluid associated with increased mortality (p=0.013). Conclusions Conservative fluid management decreases mortality for ARDS patients with a low initial central venous pressure. In this population, the administration of intravenous fluids appears to increase mortality. PMID:26741580

    Femoral or subclavian central venous catheters are commonly used for temporary vascular access in haemodialysis. We used 36 tunnelized siliconed double lumen catheter (Quinton Permcath or Hickman Bard), most of them in right internal jugular percutaneously. Indication for this catheter were acute or chronic renal failure, plasma exchange, rescue of arterio venous fistula or peritoneal dialysis. Insertion incidents were minors (local haematoma), mean functional time was 51 days. Catheters were changed in 5 cases of infection, 3 cases of obstruction and in 2 accidental remove. Insertion facility, low morbidity, potentially long time use, high blood flow rate with low recirculation argue for this expensive material.

    Objectives The purpose of this study was to test if venous blood drawn from femoral access can be used to estimate the central venous oxygen saturation and arterial lactate levels in critically ill patients. Methods Bland-Altman analysis and Spearman correlations were used to compare the femoral venous oxygen saturation and central venous oxygen saturation as well as arterial lactate levels and femoral lactate. A pre-specified subgroup analysis was conducted in patients with signs of hypoperfusion. In addition, the clinical agreement was also investigated. Results Blood samples were obtained in 26 patients. In 107 paired samples, there was a moderate correlation (r = 0.686, p < 0.0001) between the central venous oxygen saturation and femoral venous oxygen saturation with a bias of 8.24 ± 10.44 (95% limits of agreement: -12.23 to 28.70). In 102 paired samples, there was a strong correlation between the arterial lactate levels and femoral lactate levels (r = 0.972, p < 0.001) with a bias of -2.71 ± 9.86 (95% limits of agreement: -22.03 to 16.61). The presence of hypoperfusion did not significantly change these results. The clinical agreement for venous saturation was inadequate, with different therapeutic decisions in 22.4% of the situation; for lactate, this was the case only in 5.2% of the situations. Conclusion Femoral venous oxygen saturation should not be used as a surrogate of central venous oxygen saturation. However, femoral lactate levels can be used in clinical practice, albeit with caution. PMID:26761471

    PurposeTo determine the incidence and the risks factors of peripherally inserted central catheter (PICC)-related infectious complications.Materials and MethodsMedical charts of every in-patient that underwent a PICC insertion in our hospital between January 2010 and October 2013 were reviewed. All PICC-related infections were recorded and categorized as catheter-related bloodstream infections (CR-BSI), exit-site infections, and septic thrombophlebitis.ResultsNine hundred and twenty-three PICCs were placed in 644 unique patients, mostly male (68.3 %) with a median age of 58 years. 31 (3.4 %) PICC-related infections occurred during the study period corresponding to an infection rate of 1.64 per 1000 catheter-days. We observed 27 (87.1 %) CR-BSI, corresponding to a rate of 1.43 per 1000 catheter-days, 3 (9.7 %) septic thrombophlebitis, and 1 (3.2 %) exit-site infection. Multivariate logistic regression analysis showed a higher PICC-related infection rate with chemotherapy (odds ratio (OR) 7.2–confidence interval (CI) 95 % [1.77–29.5]), auto/allograft (OR 5.9–CI 95 % [1.2–29.2]), and anti-coagulant therapy (OR 2.2–95 % [1.4–12]).ConclusionChemotherapy, auto/allograft, and anti-coagulant therapy are associated with an increased risk of developing PICC-related infections.Clinical AdvanceChemotherapy, auto/allograft, and anti-coagulant therapy are important predictors of PICC-associated infections. A careful assessment of these risk factors may be important for future success in preventing PICC-related infections.

    Catheter-related infections in hemodialysis (HD) and peritoneal dialysis (PD) are one of the most common causes of morbidity and mortality in patients with end-stage renal disease. Staphylococcus aureus in HD patients and S. aureus and Pseudomonas aeruginosa in PD patients are the most common causative organisms isolated. Currently, the diagnostic tests with highest yield in suspected catheter-related infection in HD patients have not been established, and tests used for central venous catheters (CVC) in general are applied. Management of the infected HD catheter and the use of antimicrobial therapy are similar to the measures used for other CVCs, with some specific recommendations. Peritonitis is the most severe complication in PD patients. Improving hygiene conditions in catheter insertion, treatment of S. aureus nasal carriers, regular treatment of the catheter's exit site, and antibiotic lock therapy have been associated with a reduction of infectious episodes in HD and PD patients.

    There is a correlation between central venous cannulation and the development of central venous stenosis. Minor retrosternal vein lesions can be easily missed. Computerized tomographic (CT) venography is the diagnostic procedure of choice. The aim of this study was to examine the complications after catheter implantation in patients with prior permanent catheter placement and to evaluate present diagnostic procedures performed prior to choosing permanent access site in order to reduce possible complications after catheter placement. Complications of permanent CVC insertion in our department were analyzed between October 2011 and February 2015. We have implanted the Tesio twin catheter system and the Hickman Bard dual lumen catheter. All patients with prior permanent dialysis catheter were evaluated with color doppler, while patients with suspected central venous stenosis (CVS) or thrombosis were evaluated with phlebography or CT venography prior to catheter placement. One hundred and ninety-eight permanent dialysis catheters were placed (173 Tesio [87.4%] and 25 Hickman [12.6%]) in 163 patients. There were 125 patients (76.7%) with prior temporary catheter and 61 (48.8%) of them had more than one prior permanent catheter (1.92 catheter per person).There were 4/61 (6.5%) patients with catheter-related complications without prior phlebography and CT venography. Phlebography and CT venography were performed in 30 (24.0%) patients with suspected CVS/thrombosis and with dialysis vintage of 76.23 months (52.78-98.28). Phlebography and CT venography were more sensitive than color doppler in the detection of CVS/thrombosis in patients with prior permanent catheter placements (P < 0.001). Since this diagnostic algorithm was introduced prior to catheter placement there were no catheter insertion-related complications or dysfunctions (P < 0.001). All our procedures on patients with prior permanent catheters followed preliminary color doppler diagnostics. Nevertheless

    PurposeCentral venous catheterization (CVC) is estimated to be performed in millions of patients per year. Swan-Ganz catheters used for CVC are most often inserted into the internal jugular vein and during this procedure they may come into contact with the sympathetic chain. This study aims to determine the incidence of Horner's syndrome in patients admitted to intensive care unit that have undergone internal jugular CVC insertion during their admission and to determine whether ultrasonography-assisted insertion has decreased the frequency of this complication.Patients and methodsA total of 100 prospective patients admitted to the ICU were examined for the presence of anisocoria and ptosis after undergoing recent CVC. Presence of Horner's syndrome was confirmed by testing with 0.5% apraclonidine and looking for the reversal of anisocoria.ResultsFrequency of Horner's syndrome after CVC was 2% in a sample of 100 prospectively examined patients.ConclusionHorner's syndrome remains a relatively rare but definitive complication of CVC. ICU physicians should be educated about its existence and prevalence and ophthalmologists should inquire about any history of ICU admission necessitating CVC insertion in any patient presenting with Horner's syndrome.

    2008-01-01

    Purpose We conducted a phase I study of a 30-minute hepatic artery infusion of melphalan via a percutaneously placed catheter and hepatic venous hemofiltration using a double balloon catheter positioned in the retrohepatic inferior vena cava to shunt hepatic venous effluent through an activated charcoal filter and then to the systemic circulation. The purpose of the study was to demonstrate feasibility in an initial cohort and subsequently determine the maximum tolerated dose and dose-limiting toxicity of melphalan. Patients and Methods The initial cohort (n = 12) was treated with 2.0 mg/kg of melphalan before dose escalation to 3.5 mg/kg (n = 16). Total hepatic drug delivery, systemic levels, and percent filter efficiency were determined. Patients were assessed for hepatic and systemic toxicity and response. Results A total of 74 treatments were administered to 28 patients. Twelve patients with primary and metastatic hepatic tumors received 30 treatments (mean, 2.5 per patient) at an initial melphalan dose of 2.0 mg/kg. At 3.5 mg/kg, a dose-limiting toxicity (neutropenia and/or thrombocytopenia) was observed in two of six patients. Transient grade 3/4 hepatic and systemic toxicity was seen after 19% and 66% of treatments, respectively. An overall radiographic response rate of 30% was observed in treated patients. In the 10 patients with ocular melanoma, a 50% overall response rate was observed, including two complete responses. Conclusion Delivery of melphalan via this system is feasible, with limited, manageable toxicity and evidence of substantial antitumor activity; 3 mg/kg is the maximum safe tolerated dose of melphalan administered via this technique.

    Background Central nervous system vasculitis (CNSV) is a rare disorder, the pathophysiology of which is not fully understood. It involves a combination of inflammation and thrombosis. CNSV is most commonly associated with headache, gradual changes in mental status, and focal neurological symptoms. Diagnosis requires the effective use of history, laboratory testing, imaging, and biopsy. Catheter angiography can be a powerful tool in the diagnosis when common and low-frequency angiographic manifestations of CNSV are considered. We review these manifestations and their place in the diagnostic algorithm of CNSV. Summary We reviewed the PubMed database for case series of CNSV that included 5 or more patients. Demographic and angiographic findings were collected. Angiographic findings were dichotomized between common and low-frequency findings. A system for incorporating these findings into clinical decision-making is proposed. Key Message CNSV is a diagnostic challenge due to the absence of a true gold standard test. In the absence of such a test, catheter angiography remains a central piece of the diagnostic puzzle when appropriately employed and interpreted. PMID:27781050

    Cultures taken from the skin and from the hubs of short-term central venous catheters can help us to predict catheter-related bloodstream infections (C-RBSIs). The value of these cultures for such predictions has not been assessed in long-term catheters. Our objective was to assess the value of superficial cultures for the prediction of C-RBSI among patients with long-term catheters. Over a 2-year period, we prospectively obtained cultures from the skin overlying reservoir ports (group A) and from the skin insertion site and hubs of all tunneled catheters (group B). This routine was performed by vascular and interventional radiologists immediately before catheter removal (irrespective of the reason for withdrawal). Swabs were processed semiquantitatively. Catheter tips from both groups were cultured using Maki's semiquantitative technique and sonication. We also performed cultures of the reservoir ports at different sites. C-RBSI was defined as the isolation of the same species of microorganism(s) both in the colonized catheter and in at least 1 peripheral blood culture. We included 372 catheters (group A, 223; group B, 149) during the study period. The catheter colonization rate was 23.4% (87/372), and 28 patients had C-RBSI. Validity index values for the capacity of surface cultures to predict C-RBSI in groups A and B were, respectively, as follows: sensitivity, 23.5% and 45.5%; specificity, 59.7% and 63.0%; positive predictive value, 4.6% and 8.9%; and negative predictive value, 90.4% and 93.5%. Superficial cultures of patients with long-term catheters could help us to rule out the catheter as the portal of entry of bloodstream infections. Superficial cultures (from skin and hubs) proved to be a useful conservative diagnostic tool for ruling out C-RBSI among patients with long-term tunneled catheters and totally implantable venous access ports.

    Introduction. Lactate is an important indicator of tissue perfusion. The objective of this study is to evaluate if there are significant differences between the arterial and central venous measurement of lactate in pediatric patients with sepsis and/or septic shock. Methods. Longitudinal retrospective observational study. Forty-two patients were included between the age of 1 month and 17 years, with a diagnosis of sepsis and septic shock, who were admitted to the intensive care unit of a university referral hospital. The lactate value obtained from an arterial blood sample and a central venous blood sample drawn simultaneously, and within 24 hours of admission to the unit, was recorded. Results. The median age was 2.3 years (RIC 0,3–15), with a predominance of males (71.4%), having a 2.5 : 1 ratio to females. Most of the patients had septic shock (78.5%) of pulmonary origin (50.0%), followed by those of gastrointestinal origin (26.1%). Using Spearman's Rho, a 0.872 (p < 0.001) correlation was found between arterial and venous lactate, which did not vary when adjusted for age (p < 0.05) and the use of vasoactive drugs (p < 0.05). Conclusion. There is a good correlation between arterial and venous lactate in pediatric patients with sepsis and septic shock, which is not affected by demographic variables or type of vasoactive support.

    Rupture of the central veins with venous pseudoaneurysm formation is an unusual complication of central venous catheterization. Only seven cases of brachiocephalic venous pseudoaneurysm have been reported in the literature (among these only one was secondary to central venous catheterization). Plain radiographic examination of the chest may show widening of the mediastinum, pleural effusion (haemothorax), and/or opacity overlying the hemithorax of the injured vein. Further evaluation using either computed tomography or magnetic resonance imaging can be performed. Venography is considered an important tool, especially when an intervention is planned. We present the first reported case of brachiocephalic vein pseudoaneurysm treated solely with thrombin injection. The imaging, other treatment options, and literature review of brachiocephalic venous pseudoaneurysm are also discussed.

    Ten to 15% of critically ill patients need renal replacement therapy (RRT) for severe acute kidney injury. The dialysis catheter is critical for RRT quality and efficiency. Catheters have several properties that must be optimized to promote RRT success. The distal tip has to be located in a high blood flow location, which means central venous territory. Therefore, catheters are mostly inserted into the right internal jugular vein or in femoral veins. External diameter should vary from 12 to 16 Fr in order to ensure adequate blood flow inside the catheter. Lumen shapes are theoretically designed to limit thrombotic risk with low turbulences and frictional forces against the internal wall. With low aspiration pressure, distal tip shape has to deliver sufficient blood flow, while limiting recirculation rate. Catheter material should be biocompatible. Despite in vitro data, no strong evidence supports the use of coated catheters in the ICU in order to reduce infectious risk. Antibiotic "lock" solutions are not routinely recommended. Ultrasound guidance for catheterization significantly decreases mechanical complications. Clinicians should select the optimal catheter according to patient body habitus, catheter intrinsic properties and RRT modality to be used.

    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.

    β-catenin regulates the transcription of genes involved in diverse biological processes, including embryogenesis, tissue homeostasis and regeneration. Endothelial cell (EC)-specific gene-targeting analyses in mice have revealed that β-catenin is required for vascular development. However, the precise function of β-catenin-mediated gene regulation in vascular development is not well understood, since β-catenin regulates not only gene expression but also the formation of cell-cell junctions. To address this question, we have developed a novel transgenic zebrafish line that allows the visualization of β-catenin transcriptional activity specifically in ECs and discovered that β-catenin-dependent transcription is central to the bone morphogenetic protein (Bmp)-mediated formation of venous vessels. During caudal vein (CV) formation, Bmp induces the expression of aggf1, a putative causative gene for Klippel-Trenaunay syndrome, which is characterized by venous malformation and hypertrophy of bones and soft tissues. Subsequently, Aggf1 potentiates β-catenin transcriptional activity by acting as a transcriptional co-factor, suggesting that Bmp evokes β-catenin-mediated gene expression through Aggf1 expression. Bmp-mediated activation of β-catenin induces the expression of Nr2f2 (also known as Coup-TFII), a member of the nuclear receptor superfamily, to promote the differentiation of venous ECs, thereby contributing to CV formation. Furthermore, β-catenin stimulated by Bmp promotes the survival of venous ECs, but not that of arterial ECs. Collectively, these results indicate that Bmp-induced activation of β-catenin through Aggf1 regulates CV development by promoting the Nr2f2-dependent differentiation of venous ECs and their survival. This study demonstrates, for the first time, a crucial role of β-catenin-mediated gene expression in the development of venous vessels.

    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), and there was no difference between the two irradiation groups (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

    Objective To evaluate a central line care maintenance bundle to reduce central line-associated bloodstream infection (CLABSI) in non-ICU settings. Design Before-after trial with 12 month follow-up period. Setting 1250-bed teaching hospital. Participants Patients with central lines on eight general medicine wards. Four wards received the intervention and four served as controls. Intervention A multifaceted catheter care maintenance bundle consisting of educational programs for nurses, update of hospital policies, visual aids, a competency assessment, process monitoring, regular progress reports, and consolidation of supplies necessary for catheter maintenance. Results Data were collected for 25,542 catheter-days including 43 CLABSI (rate = 1.68 per 1,000 CL-days) and 4,012 catheter dressing observations. Following the intervention, a 2.5% monthly decrease in the CLABSI incidence density was observed on intervention floors, but this was not statistically significant (95% confidence interval (CI); −5.3 – 0.4). On control floors, there was a smaller, but marginally significant decrease in CLABSI incidence during the study (change in monthly rate = −1.1%; 95% CI, −2.1 - −0.1). Implementation of the bundle was associated with improvement in catheter dressing compliance on intervention wards (78.8% compliance pre-intervention vs. 87.9% during intervention/follow-up; p<0.001) but improvement was also observed on control wards (84.9% compliance pre-intervention vs. 90.9% during intervention/follow-up; P = .001). Conclusions A multi-faceted program to improve catheter care was associated with improvement in catheter dressing care, but no change in CLABSI rates. Additional study is needed to determine strategies to prevent CLABSI in non-ICU patients. PMID:26999746

    A generic feature of a wide variety of central venous catheters, which are typically located within the superior vena cava (SVC), is a jet from a side hole of the catheter tip. Particle image velocimetry is employed in conjunction with a scaled-up water facility, in order to characterize the structure of the jet as a function of dimensionless hole diameter and jet velocity ratio. Quantitative patterns in the radial and crossflow planes of the catheter-SVC system define the jet evolution. It has distinctive features, relative to the classical jet in a crossflow, which issues from a small opening in a planar surface into a region of large extent.

    Herpes zoster, commonly called shingles, is a disease that results from the reactivation of varicella zoster virus. Local trauma has been reported as a precipitant for reactivation, but this condition is rarely seen localized to a fresh surgical incision. We present the case of a patient who developed shingles overlying the incision site of a recently buried central venous access port, illustrating the need to consider this diagnosis as a unique imposter of localized infection or reaction at sites of recent procedural trauma.

    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.

    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 graft

    Patients with central venous occlusion who are ''tunneled catheter dependent'' are a challenge for hemodialysis access. A relatively new option for them is the hemodialysis reliable outflow (HeRO) device that can be totally implanted subcutaneously. However, patients still require a tunneled hemodialysis catheter that is used until the HeRO device is mature, 4 to 6 weeks later. Here, we describe a conversion of an existing tunneled hemodialysis catheter into a HeRO device, which was combined with a ''self-sealing'' Flixene graft. This allowed almost immediate use of the HeRO device without the need for placement of a catheter.

    The use of home parenteral nutrition (HPN) in patients who can not obtain their nutritional requirements by the enteral route is increasing in recent years, allowing normalization lifestyle of patients. Neoplasm and mesenteric ischaemia are some of the diseases that most frequently require HPN in Spain. However, HPN is one of the cornerstones of the treatment of much less frequent illnesses as in the case of encapsulating peritoneal sclerosis. We present the case of a patient with encapsulating peritoneal sclerosis and HPN support for more than 7 years with a peripherally inserted central catheter (PICC) for over 6 years without complications and the autonomy to perform his normal business activity. Given the exceptional nature of the case we refer it to its publication.

    A Spacelab experiment is described which proposes to obtain data on the degree of engorgement of the cephalad circulation during weightlessness by recording central venous pressure. Of practical importance is the question of how close the astronauts are to pulmonary edema and whether the pressure falls toward normal during the time of the mission. Another experiment to investigate deviations from normal fluid and mineral metabolism, possibly initiated by the central engorgement of the low pressure system, is discussed. Hormones responsible for the control of water and mineral balance (vasopressin, catecholamines, renin, aldosterone, corticosteroids, and prostaglandin E1) will be analyzed from blood samples.

    Catheter-associated infections can cause severe complications and even death. Effective antimicrobial modification of catheters that can prevent device colonization has the potential of preventing clinical infection. We studied in vitro the antimicrobial activities of central venous catheters impregnated with N-acetylcysteine (NAC), an antibiofilm agent, and a broad-spectrum antibiotic against a range of important clinical pathogens. NAC-levofloxacin-impregnated (NACLEV) catheters were also evaluated for their antiadherence activity. NACLEV catheters produced the most active and durable antimicrobial effect against both Gram-positive and Gram-negative isolates and significantly reduced colonization (P < 0.0001) by all tested pathogens compared to control catheters. These in vitro results suggest that this antimicrobial combination can potentially be used to combat catheter colonization and catheter-associated infection. PMID:23114776

    Early detection and rapid treatment of tissue hypoxia are important goals. Venous oxygen saturation is an indirect index of global oxygen supply-to-demand ratio. Central venous oxygen saturation (ScvO2) measurement has become a surrogate for mixed venous oxygen saturation (SvO2). ScvO2 is measured by a catheter placed in the superior vena cava. After results from a single-center study suggested that maintaining ScvO2 values >70% might improve survival rates in septic patients, international practice guidelines included this target in a bundle strategy to treat early sepsis. However, a recent multicenter study with >1500 patients found that the use of central hemodynamic and ScvO2 monitoring did not improve long-term survival when compared to the clinical assessment of the adequacy of circulation. It seems that if sepsis is recognized early, a rapid initiation of antibiotics and adequate fluid resuscitation are more important than measuring venous oxygen saturation.

    Antimicrobial peripherally inserted central catheters (PICCs) might reduce the incidence of central line-associated bloodstream infections (CLABSI). We tested the biocompatibility of a novel gendine-coated (combination of chlorhexidine [CHX] and gentian violet [GV]) PICC in a rabbit intravascular model and tested antimicrobial efficacy in comparison with commercially available minocycline/rifampin (M/R)- and CHX-treated PICCs in an in vitro biofilm colonization model. Gendine-coated and uncoated control PICCs were inserted in the jugular veins of rabbits for 4 days. Histopathological analysis was performed at the end of the 4-day period, and circulating levels of CHX and GV in the blood were measured at different time points using liquid chromatography-mass spectrometry. The antimicrobial efficacy of the PICCs was tested following simulated intravascular indwells of 24 h and 1 week against clinical isolates of methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Pseudomonas aeruginosa, Escherichia coli, Acinetobacter baumannii, Enterobacter cloacae, Candida albicans, and Candida glabrata. Rabbits implanted with gendine-coated PICCs exhibited reduced levels of thrombosis and inflammation compared to those of the rabbits with uncoated controls. No GV was detected in blood samples over the entire study period, and trace concentrations of CHX were detected. The gendine-coated PICCs completely prevented the adherence of all pathogens from 24 h to 1 week (P ≤ 0.001), while M/R-treated, CHX-treated, and control PICCs did not. Gendine-coated PICCs were highly effective in preventing biofilm formation of multidrug-resistant pathogenic bacteria and fungi. Gendine-coated PICCs were biocompatible in an intravascular setting. Further, the pharmacokinetic testing established that acute systemic exposures of CHX and GV from the gendine-coated catheters were well within safe levels.

    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.

    Bloodstream infection derived from an intravascular catheter occupies an important position among the various types of nosocomial infection. It is therefore necessary to establish a system for preventing catheter infection not only as measures for each separate infection, but also for the entire hospital. Catheter infections are mainly caused by contamination of the connecting part of a transfusion line during the infusion of drug solution as well as by contamination of the part of the catheter inserted. Consequently, the greatest possible care should be taken in the preparation of aseptic transfusion and the prevention of contamination when connecting a transfusion line. In particular, there are problems with three-way stopcocks, management of hubs, frequency of transfusion line exchange, fat emulsion injection method, and blood preparation. It is most important to consider effective nutritional management methods that do not require the insertion of a central venous catheter.

    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.

    To evaluate the prognostic value of CT venography for catheter-directed thrombolysis (CDT) in iliac vein compression syndrome (IVCS) patients with deep venous thrombosis (DVT). The institutional review board approved this retrospective study and waived informed consent. Among the 201 consecutive patients treated in our interventional suite for DVT from January 2001 to June 2013, 48 IVCS patients (12 men, 36 women) who underwent pre-procedural CT venography, CDT with stenting, and follow-up imaging were analyzed. To identify possible determinants of 6-month patency, CT venography was evaluated with Fisher's exact test and logistic regression analyses. Based on the analyses, image-based criteria were established and compared to the current symptom duration-based approach by receiver-operating-characteristic curve analyses and the McNemar test. Recoiling of external iliac vein (EIV) diameter (<120 %) [hazard ratio (HR) 28.652, p = .007] and severe rim enhancement (HR 20.545, p = .016) were significant risk factors for venous occlusion within 6 months of CDT. The dual-parameter image-based criteria were significantly superior to the current symptom duration-based approach in terms of area under the curve value (p = .010) and predictive accuracy (p = .031). With a 2-point cut-off, the proposed criteria demonstrated a 66.7 % sensitivity, 100.0 % specificity, and 92.9 % predictive accuracy for identifying non-responders of CDT. CT venography may be useful in assessing CDT prognoses in IVCS patients, particularly to identify non-responders who demonstrate recoiling of EIV diameter and rim enhancement on CT venography.

    Deep vein thrombosis (DVT) is a major health problem in pregnancy and postpartum period. Catheter-directed thrombolysis (CDT) is safe and effective in the management of symptomatic DVT. Value of CDT in postpartum DVT is not fully evaluated. We describe five patients presenting with acute iliofemoral DVT in their early postpartum period who were treated with mechanical thromboaspiration and CDT. The CDT was done using streptokinase infusion and unfractionated heparin. Percutaneous angioplasty was done in patients with symptomatic residual lesion following thrombolysis. Patients were discharged with oral anticoagulant and compression stockings. This approach was successful in all five cases. Percutaneous endovascular therapy using CDT, mechanical thromboaspiration, and balloon angioplasty is safe and effective in iliofemoral DVT in postpartum period. PMID:26995437

    It is not uncommon that the peripherally inserted central catheter (PICC) needs to be replaced either due to blockage or migration to a peripheral position. In such circumstances, there are two methods of PICC placement: new-site insertion and exchange by using the old PICC as a guide wire. Our objective was to investigate risk of infection associated with the exchange method. In this retrospective study, data on all PICC insertions in the neonatal intensive care unit in 2004 to 2008 were obtained. In the population who needed removal of existing PICC and insertion of a new one, we compared central line-associated bloodstream infection (CLABSI) within 1 week of insertion between the two insertion methods. Of 1148 PICC insertions reviewed, 164 (103 new-site and 61 exchange insertions) were performed after removal of a blocked/malpositioned PICC and therefore comprised the study population. The rate of CLABSI was higher in the exchange method (9.8% versus 1%, P < 0.007). After adjusting for the confounders, the odds for CLABSI within 7 days of PICC insertion was higher with the exchange method (odds ratio 25.2, 95% confidence interval: 2.17 to 292.98; P = 0.01). In infants, insertion of PICCs using the exchange method carries an increased risk of bloodstream infection.

    Compared with the excellent good results on the arterial side, venous angioplasty combined with stent-application was described relatively late in the literature, dealing in the majority of cases with palliative tumour stenoses of the superior and inferior vena cava. Recanalization of benign stenoses, especially of the pelvic venous spur (May/Thurner; syn. Pelvic compression syndrome, Cockett) was realized so far only in a limited number of cases. We have performed this interventional therapy since 1991 in 21 patients (female: 16, male: 5), with good long-term results in 18 cases. According to the special patho-anatomy of the "spur", developing intimal proliferation and progressive stenosis at the left-sided ilio-caval junction in about 20% of the average adult population, a restrictive indication is, however, mandatory. According to strong clinical symptoms (severe varicosis and leg oedema at the left-sided lower extremity), phlebographic and functional parameters (won by central venous blood pressure measurements) are indicating selected cases for this curative treatment.

  11. Prevention and management of long-term catheter related infections in cancer patients.

    Long-term central venous catheters (CVC) are necessary in the care of cancer patients. However, catheter-related bloodstream infection (CRBSI) is commonly associated with serious complications resulting in considerable morbidity and mortality. The diagnosis of CRBSI frequently requires catheter removal to confirm the diagnosis by either quantitative or semiquantitative catheter culture method. Differential time to positivity, whereby a nonquantitative blood culture drawn from the CVC that becomes positive at least 2 hr earlier than the peripheral blood culture, is a new method for the diagnosis of CRBSI without removing the catheter. Prevention of CRBSI may be accomplished with the use of strict infection control measures, antimicrobial-impregnated catheters; and antibiotic-lock technique, as well as other methods. Once infection develops, management of long-term CRBSI is dictated by the type of organism, the severity of the infection, and availability of other venous access sites. If the infection is caused by Staphylococcus aureus, gram-negative bacilli, or Candida, the catheter should be removed and systemic antimicrobial therapy given for 10-14 days or longer in cases of complicated or deep-seated infection. In some cases, where there is no other venous access site, the catheter can remain in place, but a combination of systemic antimicrobials and antibiotic-lock therapy should be used.

    The purpose of this study was to compare the technical success and complication rates of ultrasonography-guided central venous catheterization between adult and pediatric patients which have not been reported previously. In a 4-year period, 859 ultrasonography-guided central vein catheterizations in 688 adult patients and 247 catheterizations in 156 pediatric patients were retrospectively evaluated. Mean age was 56.3 years (range, 18 to 95 years) for adults and 3.3 years (range, 0.1 to 16.3 years) for children. The preferred catheterization site was internal jugular vein in 97% of adults and 85% of children. The technical success rate, mean number of punctures, and rate of single wall puncture were 99.4%, 1.04 (range, 1-3), and 83% for adults and 90.3%, 1.25 (range, 1-5), and 49% for children, respectively. All the differences were statistically significant (p < 0.05). Complication rates were 2.3% and 2.4% for adults and children, respectively (p > 0.05). Major complications such as pneumothorax and hemothorax were not seen in any group. In conclusion, ultrasonography-guided central venous catheterization has a high technical success rate, lower puncture attempt rate, and higher single wall puncture rate in adults compared to children. Complication rates are comparable in the two groups.

    Central venous catheterization is an invasive procedure which can be associated with severe complications. These include in particular unsuccessful arterial puncture and vascular injuries, which in addition to loss of blood can lead to massive soft tissue swelling. A 63-year-old female patient developed massive cervical bleeding during ultrasound-guided internal jugular vein puncture and the rapidly enlarging hematoma led to compromisation of the airway. A cannot intubate, cannot ventilate situation developed and the subsequent hypoxia led to cardiac arrest that was only resolved after emergency surgical tracheotomy during cardiopulmonary resuscitation.

    Pneumomediastinum is a rare event in subclavian central venous catheterization. However in severe thoracotraumatized patients, such as with bilateral hemopneumothorax, the catherization may be hazardous and made complex by occurrence pneumomediastinum, even the procedure is rightly carried out. We suggest that in such a risky condition, if it is mandatory, it should be carried out in a more placid condition, such as avoidance of high PEEP ventilation, setting lower tidal volume, or brief interruption of positive ventilation, to reduce the likelihood of unperceivable pneumomediastinum.

    PURPOSE We aimed to investigate the safety and functionality of tunneled transhepatic hemodialysis catheters in chronic hemodialysis patients. METHODS Thirty-eight patients (20 women aged 56±10 years and 18 men aged 61±11 years) with transhepatic tunneled hemodialysis catheters were evaluated. The date of the first transhepatic catheterization, indications, procedure details, functional time periods of catheters, reasons for the removal or revision of catheters, catheter-related complications, and current conditions of patients were retrospectively analyzed. RESULTS A total of 69 catheters were properly placed in all patients (100% technical success) under imaging guidance during the 91-month follow-up period. The functionality of 35 catheters could not be evaluated: five catheters were removed because of noncomplication related reasons (surgical fistulas were opened in two cases [2/35, 5.7%], transplantation was performed in three cases [3/35, 8.6%]), 18 patients died while their catheters were functional (18/35, 51.4%), and 12 catheters were still functional at the time of the study (12/35, 34.3%). The functionality of catheters was evaluated the remaining 34 catheters that necessitated revision because of complications. Furthermore, only half of the catheters were functional on day 136 when evaluated using Kaplan-Meier analysis. The four main complications were thrombosis (16/34, 47%; complication rate of 0.37 days in 100 catheters), infection (8/34, 23.5%; 0.18 days in 100 catheters), migration (8/34, 23.5%; 0.18 days in 100 catheters), and kinking (2/34, 6%; 0.04 days in 100 catheters). CONCLUSION Transhepatic venous catheterization is a safe and functional alternative route in chronic hemodialysis patients without an accessible central venou route. The procedure can be performed with high technical success and low complication rates under imaging guidance. PMID:27601303

    Central venous access devices (CVADs) are used in secondary and, increasingly, primary care settings to provide access to the central circulation. Skin-tunnelled catheters (STCs) are frequently used as the vascular access device of choice, particularly for patients receiving chemotherapy and for those who require long-term access for repeated transfusions. Despite the increased use of STCs, practice varies between trusts and community teams. This article provides an overview of the care and management of patients with STCs.

    Acute kidney injury (AKI) in cardiac surgery has traditionally been linked to reduced arterial perfusion. There is ongoing evidence that central venous pressure (CVP) has a pivotal role in precipitating acute renal dysfunction in cardiac medical and surgical settings. We can regard this AKI driven by systemic venous hypertension as 'kidney congestive failure'. In the cardiac surgery population as a whole, when the CVP value reaches the threshold of 14 mmHg in postoperative period, the risk of AKI increases 2-fold with an odds ratio (OR) of 1.99, 95% confidence interval (95% CI) of 1.16-3.40. In cardiac surgery subsets where venous hypertension is a hallmark feature, the incidence of AKI is higher (tricuspid disease 30%, carcinoid valve disease 22%). Even in the non-chronically congested coronary artery bypass population, CVP measured 6 h postoperatively showed significant association to renal failure: risk-adjusted OR for AKI was 5.5 (95% CI 1.93-15.5; P = 0.001) with every 5 mmHg rise in CVP for patients with CVP <9 mmHg; for CVP increments of 5 mmHg above the threshold of 9 mmHg, the risk-adjusted OR for AKI was 1.3 (95% CI 1.01-1.65; P = 0.045). This and other clinical evidence are discussed along with the underlying pathophysiological mechanisms, involving the supremacy of volume receptors in regulating the autonomic output in hypervolaemia, and the regional effect of venous congestion on the nephron. The effect of CVP on renal function was found to be modulated by ventricular function class, aetiology and acuity of venous congestion. Evidence suggests that acute increases of CVP should be actively treated to avoid a deterioration of the renal function, particularly in patients with poor ventricular fraction. Besides, the practice of treating right heart failure with fluid loading should be avoided in favour of other ways to optimize haemodynamics in this setting, because of the detrimental effects on the kidney function.

    Peripherally Inserted Central Catheter (PICC) blockage rate was audited over a two month period on the Trauma & Orthopaedics ward at our District General Hospital. A 70% (five out of seven) PICC blockage rate was observed. High blockage rates lead to potential treatment complications, delays in delivery of treatment, increase in costs, and reduction in patient satisfaction. The factors contributing to the significant blockage rate include, long and contradictory PICC care guidelines, no information sheets in the patient notes, lack of training and awareness about care of, and flushing of, PICC lines, and lack of accountability for PICC flushing. Our project aimed to achieve a greater rate of PICC patency. We produced one succinct and comprehensive PICC care guideline, carried out staff training sessions, introduced a sticker reminding staff to flush the PICC line after use, and introduced a prescription of weekly heparin saline and PRN saline flushes (for monitoring and accountability). We used questionnaires to assess competency of hospital staff pre-teaching (doctors 6%, nurses 0%), and post-teaching (doctors 70%, nurses 38%). Blockage rate data post-intervention is pending. Education improved awareness of guidelines amongst staff and we anticipate that the proposed interventions will translate into reduced blockage rates, improving patient outcomes and reducing costs.

    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.

    Acute central nervous system (CNS) toxicity and immune-related side effects are increasingly recognized with the use of monoclonal antibodies for cancer therapy. Here, we report a patient who developed of acute-onset encephalopathy and coma, which began shortly after administration of panitumumab for the treatment of metastatic colorectal cancer. Echocardiography revealed that the drug had been infused into the left cardiac ventricle via a dislocated central venous line. Diffusion-weighted magnetic resonance imaging disclosed multiple cortical hyperintensities, which were preferentially located in the frontal lobes. While the neurological condition improved within a few days, the patient died 4 weeks later. It seems likely that the administration of the antibody via the intra-arterial route contributed to the development of this condition. Toxic encephalopathy may be a hitherto unrecognized complication of panitumumab treatment and should be taken into consideration in patients developing CNS symptoms undergoing this therapy.

    Intravenous therapy teams (IVTT) provide care, education and supervision of the patient with a central line, and his/her family. This article discusses the creation of an IVTT in the Hospital Clínico San Carlos of Madrid, Spain, demonstrating its effectiveness using cost-utility analysis and outcomes indicators. In 2009 the IVTT began using a high-flow peripherally inserted central catheter (PICC) with its target population of chronic patients dependent on central venous catheters or prolonged IV treatment. The team designed activity, welfare, educational and economic indicators. Of the 98 catheters placed, 80% of patients achieved a positive response; 42% of catheters were removed after death and 30% by the end of treatment. Four percent were removed due to infection. The average implantation duration was 45 days. The economic study showed an increasing cost saving compared to peripheral catheters after 90 days of implantation, and after 77 days compared to central venous catheters. This translated into an immediate saving of 161 euros (£133.70) and 303.83 euros (£252.31) per catheter over Hickman lines and ports, as well as reduced risks, length of hospital stays and costs. The study shows PICC to be cost-effective with reported benefits to patients, professionals and organizations. The creation of the IVTT has resulted in improvements to care and the management of resources.

    Intravascular catheters and urinary catheters are the 2 most commonly inserted medical devices in the United States, and they are likewise the two most common causes of nosocomially acquired bloodstream infection. Biofilm formation on the surfaces of indwelling catheters is central to the pathogenesis of infection of both types of catheters. The cornerstone to any preventive strategy of intravascular catheter infections is strict attention to infection control practices. Antimicrobial-impregnated intravascular catheters are a useful adjunction to infection control measures. Prevention of urinary catheter–associated infection is hindered by the numbers and types of organisms present in the periurethral area as well as by the typically longer duration of catheter placement. Antimicrobial agents in general have not been effective in preventing catheter-associated urinary tract infection in persons with long-term, indwelling urethral catheters. Preventive strategies that avoid the use of antimicrobial agents may be necessary in this population. PMID:15111369

    The clinical use of veno-venous extracorporeal membrane oxygenation (VVECMO) in adult patients with respiratory failure is rapidly increasing. However, recirculation of blood oxygenated by ECMO back into the circuit may occur in VVECMO, resulting in insufficient oxygenation. The cannula position and bypass flow rate are two major factors influencing recirculation, but the relationship and ideal configuration of these factors are not fully understood. In the present study, we attempted to clarify these parameters for effective gas exchange. VVECMO was performed in eight adult goats under general anesthesia. The position of the drainage cannula was fixed in the inferior vena cava (IVC), but the return cannula position was varied between the IVC, right atrium (RA), and superior vena cava (SVC). At each position, the recirculation rates calculated, and the adequacy of oxygen delivery by ECMO in supplying systemic oxygen demand was assessed by measuring the arterial oxygen saturation (SaO2) and pressure (PaO2). Although the recirculation rates increased as the bypass flow rates increased, SaO2 and PaO2 also increased in any position of return cannula. The recirculation rates and PaO2 were 27 ± 2% and 162 ± 16 mmHg, 36 ± 6% and 139 ± 11 mmHg, and 63 ± 6% and 77 ± 9 mmHg in the SVC, RA and IVC position at 4 L/min respectively. In conclusion, the best return cannula position was the SVC, and a high bypass flow rate was advantageous for effective oxygenation. Both the bypass flow rates and cannula position must be considered to achieve effective oxygenation.

    Central venous-to-arterial carbon dioxide difference (PcvaCO2) has demonstrated its prognostic value in critically ill patients suffering from shock, and current expert recommendations advocate for further resuscitation interventions when PcvaCO2 is elevated. PcvaCO2 combination with arterial-venous oxygen content difference (PcvaCO2/CavO2) seems to enhance its performance when assessing anaerobic metabolism. However, the fact that PCO2 values might be altered by changes in blood O2 content (the Haldane effect), has been presented as a limitation of PCO2-derived variables. The present study aimed at exploring the impact of hyperoxia on PcvaCO2 and PcvaCO2/CavO2 during the early phase of shock. Prospective interventional study. Ventilated patients suffering from shock within the first 24 h of ICU admission. Patients requiring FiO2 ≥ 0.5 were excluded. At inclusion, simultaneous arterial and central venous blood samples were collected. Patients underwent a hyperoxygenation test (5 min of FiO2 100%), and arterial and central venous blood samples were repeated. Oxygenation and CO2 variables were calculated at both time points. Twenty patients were studied. The main cause of shock was septic shock (70%). The hyperoxygenation trial increased oxygenation parameters in arterial and venous blood, whereas PCO2 only changed at the venous site. Resulting PcvaCO2 and PcvaCO2/CavO2 significantly increased [6.8 (4.9, 8.1) vs. 7.6 (6.7, 8.5) mmHg, p 0.001; and 1.9 (1.4, 2.2) vs. 2.3 (1.8, 3), p < 0.001, respectively]. Baseline PcvaCO2, PcvaCO2/CavO2 and ScvO2 correlated with the magnitude of PO2 augmentation at the venous site within the trial (ρ -0.46, p 0.04; ρ 0.6, p < 0.01; and ρ 0.7, p < 0.001, respectively). Increased PcvaCO2/CavO2 values were associated with higher mortality in our sample [1.46 (1.21, 1.89) survivors vs. 2.23 (1.86, 2.8) non-survivors, p < 0.01]. PcvaCO2 and PcvaCO2/CavO2 are influenced by oxygenation changes not related to flow. Elevated

    Objective To compare central retinal venous pressure (CRVP) among eyes with and without optic disc hemorrhage (ODH) in bilateral normal-tension glaucoma (NTG) patients and NTG eyes without an episode of ODH. Methods In this prospective study, 22 bilateral NTG patients showing a unilateral ODH and 29 bilateral NTG patients without an episode of ODH were included. Eyes were categorized into group A (n = 22, eyes with ODH), group B (n = 22, fellow eyes without ODH), and group C (n = 29, NTG eyes without an episode of ODH). A contact lens ophthalmodynamometer was used to measure CRVP and central retinal arterial pressure (CRAP). Results Intraocular pressure (IOP) measured on the day of contact lens ophthalmodynamometry showed no difference among groups. However, the mean baseline IOP in group A was significantly lower than that in group C (P = .008). The CRVP in group A (29.1 ± 10.8 mmHg) was significantly lower than that in group C (40.1 ± 8.8 mmHg, P = .001), but similar to that in group B (30.5 ± 8.7 mmHg, P = .409). A similar relationship was noted for CRAP. No significant eye-associated variable for ODH was found in group A and B by conditional logistic regression analysis (all P > 0.05). However, multivariate logistic regression analysis in groups A and C revealed that low mean baseline IOP (odds ratio [OR] = 0.69, 95% confidence interval [CI] 0.49-0.98, P = 0.043) and low CRVP (OR = 0.88, 95% CI 0.80-0.95, P = 0.003) were associated with ODH. Conclusions CRVP was lower in NTG eyes with ODH than in eyes without an episode of ODH, but similar to that of fellow eyes without ODH. These imply less likelihood of association between increased central retinal venous resistance and ODH. PMID:25996599

    The Centers for Disease Control and Prevention guidelines for prevention of intravascular catheter-related infections suggest that antimicrobial-coated catheters can decrease the risk of developing catheter-related bloodstream infection in a variety of adult patient populations. There are limited data on their efficacy in the pediatric population, particularly among children with burn injuries. A study was conducted at Shriners Hospitals for Children®, Boston, to determine whether minocycline/rifampin (MR)-coated catheters could decrease the incidence of catheter-associated bloodstream infection (CABSI) in a pediatric burn population. A historical control group included all patients with double- or triple-lumen catheters inserted in the 18-month period from January 2006 to June 2007. The study group included all patients with MR antimicrobial double- or triple-lumen catheters inserted in the subsequent 18-month period, July 2007 to December 2008. Data collected included name, age, date of burn/injury, date of admission, percent TBSA area burn injury or other diagnosis, catheter site (subclavian, internal jugular, or femoral), method of insertion (new percutaneous stick or guidewire), type of catheter (double or triple lumen), date inserted, duration of catheter placement (days), and positive blood cultures recovered while the central venous catheter was in place. CABSI was defined using the Centers for Disease Control and Prevention definition of laboratory-confirmed bloodstream infection. There were a total of 66 patients with 252 catheters (1780 catheter days) in the control group and 75 patients with 263 catheters (1633 catheter days) in the study group. Age, percent burn injury, catheter site, and method of insertion were not statistically different between the two groups. The percentage of infected catheters and the rate of infection were significantly different for the two groups, with the MR antimicrobial catheters only half as likely to become infected. In

    Resting blood volumes and arterial and central venous pressures (CVP) were measured in 14 men before and after exercise training to determine whether training-induced hypervolemia is accompanied by a change in total vascular capacitance. In addition, resting levels of plasma arginine vasopressin (AVP), atrial natriuretic peptide (ANP), aldosterone (Ald), and norepinephrine (NE) were measured. The same measurements were conducted in seven subjects who did not undergo exercise and acted as controls. Exercise training consisted of 10 wk of controlled cycle exercise for 30 min/day, 4 days/wk at 75-80% of maximal O2 uptake (VO2max). A training effect was verified by a 20% increase in VO2max, a resting bradycardia, and a 9% increase in blood volume. Mean arterial blood pressure was unaltered by exercise training, but resting CVP increased by 16% (P less than 0.05). The percent change in blood volume from before to after training was linearly related to the percent change in CVP (r = 0.903, P less than 0.05). As a consequence of elevations in both blood volume and CVP, the volume-to-pressure ratio was unchanged after exercise training. Plasma AVP, ANP, Ald, and NE were unaltered. Our results indicate that elevated CVP is a consequence of training-induced hypervolemia without alteration in total effective venous capacitance.

    Resting plasma volumes, and arterial and central venous pressures (CVP) were measured in 16 men before and after exercise training to determine if training-induced hypervolemia could be explained by a change in total vascular capacitance. In addition, resting levels of plasma vasopressin (AVP), atrial natriuretic peptide (ANP), aldosterone (ALD), and norepinephrine (NE) were measured before and after training. The same measurements of vacular volume, pressures, and plasma hormones were measured in 8 subjects who did not undergo exercise and acted as controls. The exercise training program consisted of 10 weeks of controlled cycle exercise for 30 min/d, 4 d/wk at 75 to 80 percent of maximal oxygen uptake (VO2max). A training effect was verified by a 20 percent increase in VO2max, a resting bradycardia, and a 370 ml (9 percent) increase in blood volume. Mean arterial blood pressure was unaltered by exercise training, but resting CVP increased. The percent change in blood volume from before to after training was linearly related to the percent change in CVP. As a consequence of elevations in both blood volume and CVP, the volume-to-pressure ratio was essentially unchanged following exercise training. Plasma AVP, ANP, ALD, and NE were unaltered. Results indicate that elevated CVP is a consequence of training-induced hypervolemia without alteration in total effective venous capacitance. This may represent a resetting of the pressure-volume stimulus-response relation for regulation of blood volume.

    Objective The objective of our study is to assess the correlation between inferior vena cava (IVC) diameters, central venous pressure (CVP) and the IVC collapsibility index for estimating the volume status in critically ill patients. Methods This cross-sectional study used the convenient sampling of 100 adult medical intensive care unit (ICU) patients for a period of three months. Patients ≥ 18 years of age with an intrathoracic central venous catheter terminating in the distal superior vena cava connected to the transducer to produce a CVP waveform were included in the study. A Mindray diagnostic ultrasound system model Z6 ultrasound machine (Mindray, NJ, USA) was used for all examinations. An Ultrasonic Transducer model 3C5P (Mindray, NJ, USA) for IVC imaging was utilized. A paired sampled t-test was used to compute the p-values. Results A total of 32/100 (32%) females and 68/100 (68%) males were included in the study with a mean age of 50.4 ± 19.3 years. The mean central venous pressure maintained was 10.38 ± 4.14 cmH2O with an inferior vena cava collapsibility index of 30.68 ± 10.93. There was a statistically significant relation among the mean CVP pressure, the IVC collapsibility index, the mean maximum and minimum IVC between groups as determined by one-way analysis of variance (ANOVA) (p < 0.001). There was a strong negative correlation between CVP and IVC collapsibility index (%), which was statistically significant (r = -0.827, n = 100, p < 0.0005). A strong positive correlation between CVP and maximum IVC diameter (r = 0.371, n = 100, p < 0.0005) and minimum IVC diameter (r = 0.572, n = 100, p < 0.0005) was found. Conclusion There is a positive relationship of CVP with minimum and maximum IVC diameters but an inverse relationship with the IVC collapsibility index. PMID:28348943

    This study aimed to develop and assess an application software for the teaching of the procedure Manual Measurement of the Central Venous Pressure which can be used in mobile devices. The research was conducted in three phases (Survey of needs; Methodology for multimedia application development and evaluation of the multimedia application).The multimedia was the method chosen because it favors an encouraging and dynamic environment, as it integrates images and texts into an application software available for cell phones, constituting a mobile and autonomous means for learning. The research allowed to demonstrate the feasibility of the development from this pedagogical tool and open up prospects for believing that, in Nursing education, the technology available can uncover new ways of learning in a meaningful manner.

    Background Ultrasound-guided Central Venous Catheterization (CVC) for temporary vascular access, preferably using the right internal jugular vein, is widely accepted by nephrologists. However CVC is associated with numerous potential complications, including death. We describe the finding of a rare left-sided partial anomalous pulmonary vein connection during central venous catheterization for continuous renal replacement therapy (CRRT). Case presentation Ultrasound-guided cannulation of a large bore temporary dual-lumen Quinton-Mahurkar catheter into the left internal jugular vein was performed for CRRT initiation in a 66 year old African-American with sepsis-related oliguric acute kidney injury. The post-procedure chest X-ray suggested inadvertent left carotid artery cannulation. Blood gases obtained from the catheter showed high partial pressure of oxygen (PO2) of 140 mmHg and low partial pressure of carbon dioxide (PCO2) of 22 mmHg, suggestive of arterial cannulation. However, the pressure-transduced wave forms appeared venous and Computed Tomography Angiography located the catheter in the left internal jugular vein, but demonstrated that the tip of the catheter was lying over a left pulmonary vein which was abnormally draining into the left brachiocephalic (innominate) vein rather than into the left atrium. Conclusion Although several mechanical complications of dialysis catheters have been described, ours is one of the few cases of malposition into an anomalous pulmonary vein, and highlights a sequential approach to properly identify the catheter location in this uncommon clinical scenario.

    Background While hemodynamic monitoring is often performed following coronary artery bypass grafting (CABG), the relationship between postoperative central venous pressure (CVP) measurement and clinical outcomes is unknown. Methods Detailed clinical data were analyzed from 2,390 randomly selected patients undergoing high risk CABG or CABG/valve at 55 hospitals participating in the Society of Thoracic Surgeons' National Cardiac Surgery Database from 2004 to 2005. Eligible patients underwent elective/urgent isolated CABG with an ejection fraction < 40%, or elective/urgent CABG at age ≥65 years with diabetes or a glomerular filtration rate 60 mL/min per 1.73 m2. Correlation between post-operative CVP and in-hospital / 30-day mortality and renal failure was assessed as a continuous variable, both unadjusted and after adjusting for important clinical factors using logistic regression modeling. Results Mean age was 72 years, 54% of patients had diabetes mellitus, 49% were urgent procedures, and mean cardiopulmonary bypass time was 105 minutes. Patients’ CVP 6 hours post-operation was strongly associated with in-hospital and 30 day mortality: odds ratio (OR) 1.5 (95% confidence interval [CI] 1.23, 1.87) for every 5 mmHg increase in CVP, p<0.0001. This association remained significant after risk-adjustment for cardiac index: adjusted OR 1.44 (95% CI 1.10, 1.89), p<0.01. A model adjusting for cardiac index also revealed increased incidence of mortality or renal failure: adjusted OR 1.5 (95% CI 1.28, 1.86) for every 5 mmHg increase in CVP, p<0.0001. Conclusion Patients’ central venous pressure at 6 hours following CABG surgery was highly predictive of operative mortality or renal failure, independent of cardiac index and other important clinical variables. Future studies will need to assess whether post-operative CVP can be used to guide intervention and improve outcomes. PMID:25035048
