    Catheter-related bloodstream infections, exit-site infections, and tunnel infections are common complications related to hemodialysis central venous catheter use. The various definitions of catheter-related infections are reviewed, and various preventive strategies are discussed. Treatment options, for both empiric and definitive infections, including antibiotic locks and systemic antibiotics, are reviewed.

    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.

    The use of central vascular catheters (CVC) is associated with a substantial number of complications, amongst which infections predominate. A diagnosis of CVC-related infection usually requires catheter removal for culture. Semiquantitative (roll-plate method) and quantitative methods (flush, vortex, centrifugation or sonication methods) are the most reliable diagnostic methodologies requiring catheter removal, because of their greater specificity. The roll-plate method is the simplest and most commonly used technique. This method only samples the external surface of the catheter, and is particularly indicated for recently inserted catheters in which extraluminal colonisation is the primary mechanism of infection. Luminal culture techniques, such as the quantitative methods, may be more relevant for catheters that have been in place for a long period of time. However, in up to 85% of removed CVC the culture is negative, and other diagnostic techniques that do not require catheter removal have been proposed, including paired quantitative blood cultures, endoluminal brushing, and differential time to positivity (DTP) of paired blood cultures. DTP, that compares the time to positivity for qualitative cultures of blood samples simultaneously drawn from the CVC and a peripheral vein, appears to be the most reliable in the routine clinical practice since many hospitals use automatic devices for qualitative blood culture positivity detection. More recently catheter-sparing direct diagnostic methods, which include Gram stain and acridin-orange leucocyte cytospin (AOLC) test, appeared to be especially useful because of the rapidity of results and the ability to distinguish different microorganisms, allowing early targeted antimicrobial therapy.

    Full Text Available The present prospective study was carried out in the Paediatric Intensive Care Unit (PICU of a tertiary care teaching hospital in Mumbai. The objective was to determine the incidence, risk factors, mortality and organisms responsible for urinary catheter related infections (UCRI. Colonization and/or bacteriuria was labelled as urinary catheter related infection (UCRI. Forty-four patients with 51 urinary catheters were studied. Incidence of UCRI was 47.06%. Age, female sex and immunocompromised status did not increase the risk of UCRI. Duration of catheter in-situ and duration of stay in the PICU were associated with higher risk of UCRI. The mortality was not increased by UCRI. Commonest organism isolated in UCRI was E. coli, which had maximum susceptibility to nitrofurantoin and amikacin.

    Clinical criteria alone are insufficient to allow a diagnosis of intravascular catheter-related sepsis (CRS). A definite diagnosis of CRS usually requires removal of the catheter for quantitative catheter tip culture. However, only about 15-25% of central venous catheters (CVC) removed because infection is suspected actually prove to be infected, and the diagnosis is always retrospective. Other diagnostic tests, such as differential quantitative blood cultures from samples taken simultaneously from the catheter and a peripheral vein, have been proposed to avoid unjustified removal of the catheter and the potential risks associated with the placement of a new catheter at a new site: a central-to-peripheral blood culture colony count ratio of 5:1 to 10:1 is considered indicative of CRS. Despite its high specificity, the latter diagnostic technique is not routinely used in clinical practice because of its complexity and cost. The measurement of the differential time to positivity between hub blood (taken from the catheter port) and peripheral blood cultures might be a reliable tool facilitating the diagnosis of CRS in situ. In an in vitro study, we found a strong relationship between the inoculum size of various microorganisms and the time to positivity of cultures. When the times to positivity of cultures of blood taken simultaneously from central and peripheral veins in patients with and without CRS were examined, we found that earlier positivity of central vs peripheral vein blood cultures was highly correlated with CRS. Using a cut-off value of +120 min, the "differential time to positivity" of the paired blood samples, defined as time to positivity of the peripheral blood minus that of the hub blood culture, had 91% specificity and 94% sensitivity for the diagnosis of CRS. This method may be coupled with other techniques that have high negative predictive value, such as skin cultures at the catheter exit site. This diagnostic test can be proposed for routine

    Hemodialysis central venous catheter (CVC) use is associated with the highest morbidity, mortality, and cost of all types of hemodialysis vascular access. CVC-related infection drives much of the cost associated with CVC use. The magnitude of the cost associated with CVC-related infection varies depending on the type and severity of that infection; however, estimates of the total direct and indirect costs associated with hospitalizations due to hemodialysis CVC-related infections range from 17,000 USD to 32,000 USD per episode. Thus, it is critically important, to not only have effective strategies to limit CVC-related infection but also evaluate whether these strategies are an efficient use of resources. Prophylactic strategies can be considered economically efficient only if the value of its implementation and the corresponding drop in infection rate offer greater value than standard care. The optimal CVC-related infection prophylaxis strategy should work to limit infection risk with minimal risk, inconvenience, and discomfort to the patient, and at minimal cost. The aim of this review was to examine the clinical and economic impact of some commonly described interventions used for CVC infection prophylaxis.

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

    Full Text Available Abstract Backround We undertook a prospective study of all new central venous catheters inserted into patients in the intensive care units, in order to identify the risk factors and to determine the effect of glycopeptide antibiotics on catheterrelated infections. Methods During the study period 300 patients with central venous catheters were prospectively studied. The catheters used were nontunneled, noncuffed, triple lumen and made of polyurethane material. Catheters were cultured by semiquantitative method and blood cultures done when indicated. Data were obtained on patient age, gender, unit, primary diagnosis on admission, catheter insertion site, duration of catheterization, whether it was the first or a subsequent catheter and glycopeptide antibiotic usage. Results Ninety-one (30.3% of the catheters were colonized and infection was found with 50 (16.7% catheters. Infection was diagnosed with higher rate in catheters inserted via jugular vein in comparison with subclavian vein (95% CI: 1.32–4.81, p = 0.005. The incidence of infection was higher in catheters which were kept in place for more than seven days (95% CI 1.05–3.87, p = 0.03. The incidence of infection was lower in patients who were using glycopeptide antibiotic during catheterization (95% CI: 1.49–5.51, p = 0.005. The rate of infection with Gram positive cocci was significantly lower in glycopeptide antibiotic using patients (p = 0.01. The most commonly isolated organism was Staphylococcus aureus (n = 52, 37.1%. Conclusion Duration of catheterization and catheter insertion site were independent risk factors for catheter related infection. Use of glycopeptide antibiotic during catheterization seems to have protective effect against catheter related infection.

    Hospital-acquired urinary tract infections (UTI) are mainly associated with indwelling urinary catheter use. In this chapter, the pathogenesis of hospital-acquired UTI in catheterized patients, the mechanisms by which microorganisms reach the urinary tract and are able to adhere and form biofilms, and the influence of other risk factors, such as time since catheter insertion and catheter composition, are reviewed. A wide variety of infecting microorganisms can affect patients with urinary catheters, making the choice of an adequate empirical antimicrobial course complex, particularly in cases of suspected multiresistant microorganisms. Moreover, the clinical symptoms are less characteristic in catheter infection and the diagnosis may be difficult. Treatment should be stratified according to the clinical features, which can vary from asymptomatic bacteriuria that may not require treatment, to severe septic episodes that need wide antibiotic coverage. The prevention measures for UTI in permanently catheterized patients are reviewed. Infections of the female genital tract associated with foreign bodies are mainly related to the use of intrauterine devices (IUDs). The epidemiology, microbiology profile, antimicrobial treatment, and prophylaxis of pelvic inflammatory disease related to IUD use in women are also reviewed.

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

    Full Text Available BACKGROUND AND AIMS: Patients on home parenteral nutrition (HPN are at risk for catheter-related complications; mainly infections and occlusions. We have previously shown in HPN patients presenting with catheter sepsis that catheter locking with taurolidine dramatically reduced re-infections when compared with heparin. Our HPN population therefore switched from heparin to taurolidine in 2008. The aim of the present study was to compare long-term effects of this catheter lock strategy on the occurrence of catheter-related bloodstream infections and occlusions in HPN patients. METHODS: Data of catheter-related complications were retrospectively collected from 212 patients who received HPN between January 2000 and November 2011, comprising 545 and 200 catheters during catheter lock therapy with heparin and taurolidine, respectively. We evaluated catheter-related bloodstream infection and occlusion incidence rates using Poisson-normal regression analysis. Incidence rate ratios were calculated by dividing incidence rates of heparin by those of taurolidine, adjusting for underlying disease, use of anticoagulants or immune suppressives, frequency of HPN/fluid administration, composition of infusion fluids, and duration of HPN/fluid use before catheter creation. RESULTS: Bloodstream infection incidence rates were 1.1/year for heparin and 0.2/year for taurolidine locked catheters. Occlusion incidence rates were 0.2/year for heparin and 0.1/year for taurolidine locked catheters. Adjusted incidence ratios of heparin compared to taurolidine were 5.9 (95% confidence interval, 3.9-8.7 for bloodstream infections and 1.9 (95% confidence interval, 1.1-3.1 for occlusions. CONCLUSIONS: Given that no other procedural changes than the catheter lock strategy were implemented during the observation period, these data strongly suggest that taurolidine decreases catheter-related bloodstream infections and occlusions in HPN patients compared with heparin.

    Full Text Available We report a case of a patient who experienced a catheter-related bloodstream infection caused by Staphylococcus condimenti, which was first isolated from soy sauce mash. This is the first reported case of human infection. Although blood culture isolates and the catheter tip tube did not reveal coagulase or clumping factor, false-positive results were obtained from latex agglutination tests for clumping factor and protein A due to self-agglutination. Care is needed when performing only latex agglutination test without a coagulase test. Further studies are needed to determine the pathogenic potential of S. condimenti based on appropriate identification.

    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.

    This prospective randomized controlled study with 975 nontunneled central venous catheters (CVCs) showed that the semiquantitative roll-plate culture technique (SQC) was as accurate as the sonication method for diagnosis of catheter-related infections. Sonication is difficult to standardize, whereas SQC is simpler, faster, and as reliable as the sonication method for culturing CVCs.

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

    The majority of catheter-related bloodstream infections (CR-BSI) are associated with central venous catheters (CVCs) and most of them develop in patients staying at intensive care units (ICUs). The aim of this study was to assess the performance of different methods for the diagnosis of CR-BSI in neurology and neurosurgery ICUs of our hospital. This prospective study was carried out between January 2007 and January 2008 and all of the patients were followed daily for CR-BSI after the insertion of CVCs. Blood cultures were taken simultaneously from the catheter lumen and from at least one peripheral vein when there was a suspicion of CR-BSI. Additionally, from patients whose CVCs were removed, catheter tip cultures were taken and from patients with exit site infection, cultures of the skin surrounding the catheter entrance were taken. Catheter tip cultures were done by using quantitative and semiquantitative culture methods. Blood cultures taken from the catheter lumen and peripheral vein were incubated in the BACTEC 9050 (Becton Dickinson, USA) automated blood culture system. Gram and acridine orange (AO) staining were used for the smears prepared from the catheter tips and blood cultures. To evaluate the value of culture and staining methods in the diagnosis of CR-BSI; sensitivity, specificity, positive and negative predictive values (PPV and NPV, respectively) of each method were determined. A total of 148 patients (66 male, 82 female; age range: 1-94 years, mean age: 58.7 ± 21.8 years) were included in the study, of whom 67 (45.3%) were from neurology and 81 (54.7%) were from neurosurgery ICUs. One hundred ninety-nine CVC application performed in 148 patients were evaluated. Mean duration of catheterization was 8.5 ± 5.2 days. Thirty-two episodes of CR-BSI among 199 catheterizations (16%) in 29 patients among a total of 148 patients (19.6%) were determined. The most frequently isolated microorganisms were methicillin-resistant coagulase-negative staphylococci

    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.

    This study was done to establish a mouse model for catheter-related biofilm infection suitable to bioluminescence imaging (BLI). Biofilm formation of Pseudomonas aeruginosa (P. aeruginosa) Xen5 grown on catheter disks in vitro and in an implanted mouse model was real-time monitored during a 7-day study period using BLI. The numbers of integrated brightness (IB) and viable bacterial count (VBC) in the biofilm disks in vitro were highest at 24 h after inoculation; the IB of biofilm in vivo was increased until 24 h after implantation. A statistical correlation was observed between IB and VBC in vitro by linear regression analysis. The actual VBC value in vivo can be estimated accurately by IB without sacrifice. In addition, we monitored the change in white blood cells (WBCs) during infection. The number of WBCs on day 7 was significantly higher in the infection group than in the control group. This study indicates that BLI is a simple, fast, and sensitive method to measure catheter biofilm infection in mice.

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

    A 49-year-old woman visited our emergency department because of exertional dyspnea due to severe left ventricular functional failure. It progressed to disseminated intravascular coagulation and disturbance of consciousness on day 67 of admission. Gram-positive bacilli were detected from two different blood culture samples on day 67 of admission. An API-Coryne test and sequencing (1~615 bp) of the 16S rRNA gene were performed, and the strain was identified as Corynebacterium striatum. The bacterium was detected from the removed central venous catheter tip too, and the patient was diagnosed with catheter-related bloodstream infection by C. striatum. However, treatment was not effective, and the patient died on day 73 of admission. PMID:28197349

    Taurolidine is an antimicrobial agent that was originally used in the local treatment of peritonitis and was shown to be effective in the prevention of catheter-related bloodstream infections (CR-BSI). In this pilot study, we used taurolidine solution as an intravenous (i.v.) lock into the totally implantable intravascular devices of 11 consecutive oncological patients with catheter-related bloodstream infections not responding to systemic antimicrobial chemotherapy. All patients recovered completely from the infection. No adverse drug effects were seen. Three patients were successfully retreated for a recurrent infection. Our data suggest a beneficial role of taurolidine i.v. lock for the therapy of catheter-related bloodstream infections in oncological patients. Taurolidine i.v. lock application is feasible and could especially be useful in infections resistant to antibiotic chemotherapy.

    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.

    Central venous access devices (CVAD) are increasingly being used for optimal delivery of clotting factor concentrates in patients with haemophilia with poor peripheral venous access. The utility of CVAD is particularly well recognized in young patients starting factor prophylaxis and in patients with inhibitors undergoing immune tolerance induction (ITI). A catheter-related infection (CRI) remains the most common complication of CVAD in haemophilia patients and is the most frequent indication for its removal. Additionally, in some patients the infection results in significant morbidity and mortality and also contributes to failure of the ITI regimen. Ethanol-lock therapy (ELT) is a treatment modality that has been used to treat CRI in patients with indwelling catheters for home parenteral nutrition and chemotherapy. The aim of this study was to report the success in treating CRI in haemophilia patients using ELT. Three severe haemophilia A patients undergoing ITI regimen who developed CVAD infections resistant to conventional management with antibiotics were treated by ELT according to the institutional technique. All three patients responded well to ELT with clearance of the CVAD infection. There were no adverse side effects. To our knowledge, this is the first report of ELT in patients with haemophilia. The role of ELT needs to be investigated in larger studies for treatment of CRI in patients with bleeding disorders.

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

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

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

Problem: Measuring a process of care in real time is essential for continuous quality improvement (CQI). Our inability to measure the process of central venous catheter (CVC) care in real time prevented CQI efforts aimed at reducing catheter related bloodstream infections (CR-BSIs) from these devices. Design: A system was developed for measuring the process of CVC care in real time. We used these new process measurements to continuously monitor the system, guide CQI activities, and deliver performance feedback to providers. Setting: Adult medical intensive care unit (MICU). Key measures for improvement: Measured process of CVC care in real time; CR-BSI rate and time between CR-BSI events; and performance feedback to staff. Strategies for change: An interdisciplinary team developed a standardized, user friendly nursing checklist for CVC insertion. Infection control practitioners scanned the completed checklists into a computerized database, thereby generating real time measurements for the process of CVC insertion. Armed with these new process measurements, the team optimized the impact of a multifaceted intervention aimed at reducing CR-BSIs. Effects of change: The new checklist immediately provided real time measurements for the process of CVC insertion. These process measures allowed the team to directly monitor adherence to evidence-based guidelines. Through continuous process measurement, the team successfully overcame barriers to change, reduced the CR-BSI rate, and improved patient safety. Two years after the introduction of the checklist the CR-BSI rate remained at a historic low. Lessons learnt: Measuring the process of CVC care in real time is feasible in the ICU. When trying to improve care, real time process measurements are an excellent tool for overcoming barriers to change and enhancing the sustainability of efforts. To continually improve patient safety, healthcare organizations should continually measure their key clinical processes in real

    2014-11-01

    The nosocomial pathogen Pseudomonas aeruginosa is equipped with a large arsenal of cell-associated and secreted virulence factors which enhance its invasive potential. The complex relationships among virulence determinants have hitherto not been fully elucidated. In the present study, 175 catheter-related isolates were observed for the presence of selected virulence factors, namely extracellular enzymes and siderophore production, biofilm formation, resistance to antibiotics, and motility. A high percentage of the strains produced most of the tested virulence factors. A positive correlation was identified between the production of several exoproducts, and also between the formation of both types of biofilm. An opposite trend was observed between the two types of biofilm and the production of siderophores. Whereas the relationship between the submerged biofilm production (i.e. the biofilm formed on the solid surface below the water level) and the siderophore secretion was negative, the production of air-liquid interface (A-L) biofilm (i.e. the biofilm floating on the surface of the cultivation medium) and the siderophore secretion were positively correlated. All correlations were statistically significant at the level P = 0.05 with the correlation coefficient γ ≥ 0.50. Our results suggest that: (1) the co-production of the lytic enzymes and siderophores can play an important role in the pathogenesis of the catheter-related infections and should be taken into account when the virulence potential is assessed; (2) biofilm-positive strains are capable of forming both submerged and non-attached A-L biofilms; and (3) the different micro-environment in the submerged biofilm and A-L biofilm layers have opposite consequences for the production of other virulence factors.

    2005-03-05

    Regardless of the repeated reservations raised by countless researchers with reference to the use of catheters as vascular access for haemodialysis (HD), central venous catheters (CVCs) remain irreplaceable tools of the modern dialysis delivery system as a reliable option for the clinical situations requiring instant access to circulation, for various reasons. Patients on long-term haemodialysis are therefore at a significantly high risk for catheterrelated bloodstream infections (CRBSI) and ensuing serious complications. Although early systemic antibiotic treatment should include the coverage for Staphylococcus aureus, the pathogen with most devastating consequences including bacterial endocarditis; optimal treatment of CRBSI while preserving the catheter site, remains contentious. Nonetheless, catheter exchange over a guide wire and antimicrobial-anticoagulant "locks" have shown promising results as novel access salvage techniques. Despite the fact that a number of novel potentially useful strategies for the prevention of CRBSI are in the pipeline; equally essential however, remains the role of rigorous implementation of standard infection control measures for hygiene and aseptic handling of CVCs in long-term HD patients. The policy of increasing the AVF (arteriovenous fistula) prevalence beyond 50% while minimising the use of CVCs, dependent largely upon the timely referrals and prudently implemented pre-ESRD program - ought to have a positive impact on long-term HD outcomes.

    Corynebacterium diphtheriae still represents a global medical challenge, particularly due to the significant number of individuals susceptible to diphtheria and the emergence of non-toxigenic strains as the causative agents of invasive infections. In this study, we characterized the clinical and microbiological features of what we believe to be the first case of C. diphtheriae infection of a percutaneous nephrostomy catheter insertion site in an elderly patient with a fatal bladder cancer. Moreover, we demonstrated the potential role of adherence, biofilm formation and fibrin deposition traits in C. diphtheriae from the catheter-related infection. Non-toxigenic C. diphtheriae isolated from the purulent discharge (named strain BR-CAT5003748) was identified by the API Coryne system (code 1 010 324) and a multiplex PCR for detection of dtxR and tox genes. Strain BR-CAT5003748 showed resistance to oxacillin, ceftazidime and ciprofloxacin. In experiments performed in vitro, the catheter isolate was classified as moderately hydrophobic and as moderately adherent to polystyrene surfaces. Glass provided a more effective surface for biofilm formation than polystyrene. Micro-organisms adhered to (>1.5 x 10(6) c.f.u.) and multiplied on surfaces of polyurethane catheters. Microcolony formation (a hallmark of biofilm formation) and amorphous accretions were observed by scanning electron microscopy on both external and luminal catheter surfaces. Micro-organisms yielded simultaneous expression of localized adherence-like and aggregative-like (LAL/AAL) adherence patterns to HEp-2 cells. Interestingly, the coagulase tube test resulted in the formation of a thin layer of fibrin embedded in rabbit plasma by the non-toxigenic BR-CAT5003748 strain. In conclusion, C. diphtheriae should be recognized as a potential cause of catheter-related infections in at-risk populations such as elderly and cancer patients. LAL/AAL strains may be associated with virulence traits that enable C

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

    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.

    Full Text Available 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.

    Full Text Available As long-standing clinical problems, catheter-related infections and other chronic biofilm infections are more difficult to treat due to the high antibiotic resistance of biofilm. Therefore, new treatments are needed for more effective bacteria clearance. In this study, we evaluated the antibacterial activities of several common antibiotics alone and their combinations against biofilm-embedded methicillin-resistant staphylococcus aureus (MRSA infections, both in vitro and in vivo. In brief, fosfomycin, levofloxacin, and rifampin alone or in combination with linezolid were tested in vitro against planktonic and biofilm-embedded MRSA infection in three MRSA stains. The synergistic effects between linezolid and the other three antibiotics were assessed by fractional inhibitory concentration index (FICI and time-kill curves, where the combination of linezolid plus fosfomycin showed the best synergistic effect in all strains. For further evaluation in vivo, we applied the combination of linezolid and fosfomycin in a catheter-related biofilm rat model and found that viable bacteria counts in biofilm were significantly reduced after treatment (P<0.05. In summary, we have shown here that the combination of linezolid and fosfomycin treatment had improved therapeutic effects on biofilm-embedded MRSA infection both in vitro and in vivo, which provided important basis for new clinical therapy development.

    Full Text Available Blood stream infections related to central venous catheterization are one of the major device-associated infections reported. Patients admitted in critical care units requiring central venous catheterization and presenting with signs of septicemia during catheterization period were investigated for catheter-related blood stream infections (CRBSI. The CRBSI rate was 9.26 per 1000 catheter days in general with highest rate in neonatal intensive care unit (27.02/1000 days. Site of insertion of catheter and duration of catheterization did not show the influence on the CRBSI rate. Coagulase-negative Staphylococci were the predominant cause. Mortality of 33% was observed in patients with CRBSI. Since central venous catheters are increasingly being used in the critical care, regular surveillance for infection associated them are essential.

    Hom parenteral nutrition (HPN) is a nutritional support modality that allows for the supply of parenteral nutrition bags to the patient's home. Since its first use in the late 60s, this therapy has allowed maintaining patients with intestinal failure alive that previously were doomed to death. In our country, this therapy is used by 2.15 patients pmp. According to the NADYA data, catheter-related infections account for 50% of all HPN-related complications. In larger series, infection rates are 0.5-2 infections/1000 days or 0.3-0.5 infections/patient/year. Most of them are produced by gram-positive organisms that migrate from the skin or from catheter connections to the tip. These infections are diagnosed by means of clinical data and with different microbiological cultures. When treating these infections, it is important to keep the catheter in place, and administering antibiotics through it, conventionally or with the antibioticolade technique.

    2013-01-01

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

    Full Text Available Background: Totally, implantable access ports (TIAPs are used for long standing venous catheterization. This study was designed to present our experiences of the TIAPs applications and efficacy of Taurolidine-citrate lock solution (TCLS against catheter-related infections. Materials and Methods: We evaluated records of the 108 patients implanted with 112 TIAPs, which had been performed using heparin solution or TCLS between 2005 and 2013. Results: Duration of exposure to TIAPs was 17-2051 days (median: 411 days. The primary diagnoses were solid tumours (n = 57, lymphoma (n = 23, haematologic diseases (n = 23, nephrotic syndrome (n = 4, Hirschsprung disease (n = 1. The right external jugular vein was most frequently used vascular access route (72.3%. Mechanical complications were observed in four cases. TIAPs were removed due to remission in 19 cases and infection in 19 cases. Median time from implantation and to the development of infection was 60 days. Heparin solution had been used for care in 33 ports, whereas heparin and TCLS had been used in 79 ports. Based on statistical comparison, use of TCLS was considered to be an important factor for preventing infection (P = 0.03. Conclusion: We consider that TCLS reduces infection prevalence so TIAPs would be used more extensively and effectively to prevent infections.

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

    Catheter-related infections are one of the most serious complications of TPN therapy. Nurses have important responsibilities in the care of patients who are receiving TPN. This quasi-experimental study was conducted for the purpose of investigating the effectiveness of an educational intervention on changing nursing practice and preventing catheter-related infections in patients receiving total parenteral nutrition. The nurses' practice and the colonisation rate of control and comparative group patients in the surgical clinics of Hacettepe University Hospital (Turkey), and related variables were examined before and after an educational intervention. The findings of the study indicate that the intervention was successful in improving appropriate nursing practice, mean scores of nurses' practices were 45.7 before and 66.5 after the intervention (p<0.05). The rate of microorganism colonisation was also decreased but statistical analysis demonstrated no association between nursing practices and microorganism colonisation of catheter cultures.

    Risks for development of local and/or systemic infections are the most important complications of catheters that are widely used during hospitalization process. The aims of this study were to investigate and compare the antibiotic susceptibilities of methicillin-resistant staphylococci isolated from catheters, in planktonic and biofilm forms, and to evaluate the antimicrobial effects of antibiotics on those forms alone and in combinations. A total of 30 strains [15 methicillin-resistant Staphylococcus aureus (MRSA) and 15 methicillin-resistant coagulase-negative staphylococci (MR-CNS)] isolated from catheter cultures of patients hospitalized in different clinics and intensive care units in Baskent University Medical School Hospital between 2006-2009, were included in the study. The antibiotic sensitivities of MRSA and MR-CNS isolates were investigated in vitro in planktonic phase and on sessile cells after biofilm was formed. Vancomycin, ciprofloxacin, rifampicin, gentamicin, meropenem, tigecycline, linezolid, ceftazidime and cephazolin were used for antibiotic susceptibility testing. The sensitivity of planktonic cells to antibiotics was primarily investigated, so that minimal inhibitor concentration (MIC) and minimal bactericidal concentration (MBC) values were determined by broth microdilution method. Afterwards, each strain was transformed to sessile cell in a biofilm environment, and MIC and MBC values were also determined for sessile cells. Double and triple antibiotic combinations were prepared, the effectiveness of combinations were studied on both planktonic and biofilm cells with multiple-combination bactericidal testing (MCBT) method. The data set obtained from planktonic and biofilm cells for each antibiotic analyzed via two proportion z test. Statistically significant decreases were found in the sensitivities of sessile cells when compared to planktonic cells (pantibiotic combinations also showed the susceptibility decrease between planktonic and

    2004-01-01

    The overall incidence of vertebral osteomyelitis is increasing due to, the increasing rates of bacteraemia due to intravascular devices. We report a patient with end-stage renal failure under hemodialysis by internal jugular catheters who started with back pain after several episodes of Staphylococcus aureus bacteraemia, and whose magnetic resonance imaging was showed signs suggestive of spondylodiscitis. Other 4 similar cases from our service have been analysed, thereby we can conclude the most effective treatment of vertebral osteomyelitis and/or epidural abscess is premature diagnosis of these pathologies. Magnetic resonance imaging is the most sensitive radiologic technique whom we have. Treatment of vertebral osteomyelitis must be preceded by a correct bacteriological diagnosis. Surgery plays a central role in the successful treatment and should be performed as soon as neurological problems are apparent.

    2012-12-01

    We report the case of a patient with a stage IV b pancreatic cancer in which epidural/subcutaneous reservoir therapy was effective for pain control. However, a catheter-related infection caused by methicillin-resistant Staphylococcus aureus (MRSA)was occurred. In recent years, the number of cancer patients desiring palliative home-based care in Japan has increased. Epidural/subcutaneous reservoir therapy is often offered to relieve refractory pain, and to reduce the side effects of systemic administration of opioids, such as drowsiness, in homecare patients. We believe that this patient may have been able to continue home-based care if the catheter-related infection did not occur, because a significant improvement was calculated in the pain level by the numerical rating scale(NRS)observed. It is important to establish and share common strict guidelines between hospital doctors and general practitioners for the management of the subcutaneous catheter and reservoir therapy in order to prevent catheter-related infections over a long period.

    2015-12-01

    Biofilm-related infections have become an increasingly important clinical problem. Many of these infections occur in patients with multiple comorbidities or with impaired immunity. Echinocandins (caspofungin, micafungin, and anidulafungin) exert their fungicidal activity by inhibition of the synthesis of the (1→3)-β-d-glucan. They are active among in vitro and in vivo model systems against a number of Candida species and filamentous fungi in their planktonic and biofilm phenotype. Their superior activity against biofilms poses them in an advantageous position among the antifungal armamentarium. However, additional studies are warranted to expand our knowledge on the role of echinocandins against biofilm-related infections.

    2016-01-01

    We investigated the prognostic role of high MICs for antistaphylococcal agents in patients with methicillin-sensitive Staphylococcus aureus catheter-related bloodstream infection (MSSA CRBSI). We prospectively reviewed 83 episodes from 5 centers in Spain during April 2011–June 2014 that had optimized clinical management and analyzed the relationship between E-test MICs for vancomycin, daptomycin, oxacillin, and linezolid and development of complicated bacteremia by using multivariate analysis. Complicated MSSA CRBSI occurred in 26 (31.3%) patients; MICs for vancomycin and daptomycin were higher in these patients (optimal cutoff values for predictive accuracy = 1.5 μg/mL and 0.5 μg/mL). High MICs for vancomycin (hazard ratio 2.4, 95% CI 1.2–5.5) and daptomycin (hazard ratio 2.4, 95% CI 1.1–5.9) were independent risk factors for development of complicated MSSA CRBSI. Our data suggest that patients with MSSA CRBSI caused by strains that have high MICs for vancomycin or daptomycin are at increased risk for complications. PMID:27192097

    Full Text Available There is an enormous knowledge base in the field of health which has no application. Its growth is not limited by its discovery but by the lack of its implementation. The necessity of implementing conclusions is evident in evaluating the real repercussion on quality daily cares; as “strategies” and “outcomes”. In talking about oncohematological nursing, some health outcomes would be: the reduction of adverse events such as nosocomial infections and pressure ulcers. Consequently, our objective has been: to find and summarize the evidences about Venous Catheterization and Pressure Ulcers; in order to encourage the spread of knowledge and promote changes in practice.Method: Databases as CINAHL, MEDLINE, Cochrane Library, EMBASE, Pascal Biomed, LILACS, CUIDEN, CUIDEN qualitative y CUIDATGE were revised in Spanish, French and English. No time restrictions were applied.Findings: The main findings and recommendations were synthesised on a poster, next to suggestions for practical changes to implement, evidence levels used, and the clinic problem significance. The suggested changes arose from nursing staff based on evidences found that includes behaviours and attitudes changes, which should facilitate more rapid innovations diffusion.

    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.

    导管相关性血流感染(CRBSI)是重症加强治疗病房(ICU)中常见的严重感染之一,可增加患者的病死率,延长住院时间,增加住院费用.在CRBSI中,动脉导管相关性血流感染(AC-BSI)常被忽视或低估,目前的报道显示,AC-BSI的发生率接近甚至不低于中心静脉导管相关性血流感染(CVC-BSI).一旦怀疑AC-BSI,应在留取相关培养物培养后立即拔出动脉导管,并根据患者的情况实施抗感染治疗;预防是减少AC-BSI的关键.本文作者从AC-BSI的流行病学、病原学及发病机制、危险因素、诊断、治疗和预防等方面的进展进行综述,以期为临床处理提供帮助.%Catheter-related bloodstream infection (CRBSI) is one of the common severe infections in intensive care unit (ICU),which tends to increase the mortality of patients,the length of hospital stay and the cost of hospitalization.Arterial catheter-related bloodstream infection (AC-BSI) is often overlooked or underestimated.Some studies pointed out that the incidence of AC-BSI is close to or even higher than central venous catheter related bloodstream infection (CVC-BSI),which plays an important role in catheter-related infections.Once AC-BSI is suspected,arterial catheter should be removed immediately after bacterial culture and antibiotics should be prescribed according to severities of patients.Prevention is the key to reduce AC-BSI.The research progress of epidemiology,etiology,pathogenesis,risk factors,diagnosis,treatment and prevention of AC-BSI was reviewed to facilitate the clinical decision.

  3. Totally implantable catheter embolism: two related cases

    Directory of Open Access Journals (Sweden)

    Rodrigo Chaves Ribeiro

    Full Text Available CONTEXT AND OBJECTIVE: Long-term totally implantable catheters (e.g. Port-a-Cath® are frequently used for long-term venous access in children with cancer. The use of this type of catheter is associated with complications such as infection, extrusion, extravasation and thrombosis. Embolism of catheter fragments is a rare complication, but has potential for morbidity. The aim here was to report on two cases in which embolism of fragments of a long-term totally implantable catheter occurred. DESIGN AND SETTING: Case series study at Hospital do Servidor Público Estadual, São Paulo. METHODS: Retrospective review of catheter embolism in oncological pediatric patients with long-term totally implantable catheters. RESULTS: The first patient was a 3-year-old girl diagnosed with stage IV Wilms' tumor. Treatment was started with the introduction of a totally implantable catheter through the subclavian vein. At the time of removal, it was realized that the catheter had fractured inside the heart. An endovascular procedure was necessary to remove the fragment. The second case was a boy diagnosed with stage II Wilms' tumor at the age of two years. At the time of removal, it was noticed that the catheter had disconnected from the reservoir and an endovascular procedure was also necessary to remove the embolized catheter. CONCLUSION: Embolism of fragments of totally implantable catheters is a rare complication that needs to be recognized even in asymptomatic patients.

  4. Taurolidine lock solutions for the prevention of catheter-related bloodstream infections: a systematic review and meta-analysis of randomized controlled trials.

    Yong Liu

    Full Text Available BACKGROUND: Catheter-related bloodstream infections (CRBSIs are a significant cause of morbidity and mortality in critically ill patients, contributing to prolonged hospital stays and increased costs. Whether taurolidine lock solutions (TLS are beneficial for the prevention of CRBSIs remains controversial. In this meta-analysis, we aim to assess the efficacy of TLS for preventing CRBSIs. METHODS: We conducted a systematic search of PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. Eligible studies included randomized controlled trials that reported on the effects of TLS for preventing CRBSIs. The primary outcome in these studies was catheter-related bloodstream infections, with microbial distribution of CRBSI and catheter-associated thrombosis as secondary outcomes. Data were combined using random-effects models owing to significant clinical heterogeneity. RESULTS: Six randomized controlled trials (RCTs conducted from 2004 through 2013 involving 431 patients and 86,078 catheter-days were included in the review. TLS were significantly associated with a lower incidence of CRBSIs when compared to heparin lock solutions (Risk Ratio [RR], 0.34; 95% Confidence Interval [CI], 0.21-0.55. Use of TLS significantly decreased the incidence of CRBSIs from gram-negative (G- bacteria (P = 0.004; RR, 0.27; CI, 0.11-0.65, and was associated with a non-significant decrease in gram-positive (G+ bacterial infections (P = 0.07; RR, 0.41; CI, 0.15-1.09. No significant association was observed with TLS and catheter-associated thrombosis (RR, 1.99; CI, 0.75-5.28. CONCLUSIONS: The use of TLS reduced the incidence of CRBSIs without obvious adverse effects or bacterial resistance. However, the susceptibility of G+ and G- bacteria to taurolidine and the risk for catheter-associated thrombosis of TLS are indeterminate due to limited data. The results should be treated with caution due to the limited sample sizes and methodological deficiencies

    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 %.

    Central venous catheter( CVC )is one of the most common technique for monitoring and treatment in ICU. But There is a risk of catheter-related bloodstream infection causing prolonged hospital stay and increased mortality. Positioning the CVC through the subclavian vein and using a antibiotic catheter can help to reduce the incidence of CRBSI. A bundle stratige is of a crucial role in CRBSI provention.It should include strict hand hygiene, sterilizing with mixture of 70% ethano and 2% chlorhexidine, maximal sterile barrier and regular dressing change. The efficiency of regular CVC replacement and of antibiotic based catheter lock solution are not clear, and are not recommended as a routine.%留置中心静脉导管是ICU中最常用的监测和治疗措施,但其同时存在发生导管相关性血流感染(CRBSI)的风险,从而导致患者住院时间延长和病死率升高.选择锁骨下穿刺径路、使用抗生素导管可减少CRBSI的发生.应用集束化预防措施进行置管及日常护理是预防CRBSI发生的重要措施,包括严格的手卫生、应用2%氯己定和70%乙醇混合液消毒皮肤、最大消毒屏障以及定期更换辅料.定期更换导管及使用抗生素封管对预防CRBSI效果不明确,不作为常规推荐.

  13. Central Venous Catheter-Related Hydrothorax

    Directory of Open Access Journals (Sweden)

    Se Hun Kim

    2015-11-01

    Full Text Available This report describes a case of 88-year-old women who developed central venous catheter-related bilateral hydrothorax, in which left pleural effusion, while right pleural effusion was being drained. The drainage prevented accumulation of fluid in the right pleural space, indicating that there was neither extravasation of infusion fluid nor connection between the two pleural cavities. The only explanation for bilateral hydrothorax in this case is lymphatic connections. Although vascular injuries by central venous catheter can cause catheter-related hydrothorax, it is most likely that the positioning of the tip of central venous catheter within the lymphatic duct opening in the right sub-clavian-jugular confluence or superior vena cava causes the catheter-related hydrothorax. Pericardial effusion can also result from retrograde lymphatic flow through the pulmonary lymphatic chains.

    1998-03-01

    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.

    Emerging evidence suggests taurolidine reduces the risk of repeated episodes of catheter related blood stream infections (CRBSI) in a subgroup of patients receiving home parenteral nutrition (HPN). We defined 3 indications where taurolidine could be considered and retrospectively analysed data from patients who were treated over a 10 year period to examine the validity of these criteria. Twenty-two patients were identified from a total HPN population of 81, representing 33.2 years of experience. The overall CRBSI rate pre- and post-taurolidine usage was reduced from 5.71 to 0.99 infections per 1000 patient parenteral nutrition days (P-value taurolidine is used as secondary prophylaxis and providing initial data suggesting the benefit of its use as primary prophylaxis.

    Full Text Available A relationship between central venous catheter (CVC tip colonisation and catheter-related blood-stream infection (CRBSI has been suggested. We examined culture positivity of CVC tips (colonised and infected CVCs in a total parenteral nutrition (TPN population. Our aims were to define the relationship between culture positivity and CRBSI, and to compare causative organisms between culture positive and CRBSI CVCS, and between ward and ICU CVCs. All patients receiving TPN via non-tunnelled CVCs during the study (1997–2009 were included. All CVC tips were analysed. Data were collated contemporaneously. A TPN audit committee determined whether CVC tip culture positivity reflected colonisation/CRBSI using CDC criteria. 1,392 patients received TPN via 2,565 CVCs over 15,397 CVC days. 25.4% of CVCs tips were culture positive, of these 32% developed CRBSI. There was a nonsignificant trend of higher Gram negative Bacilli isolation in ICU CVCs (=0.1, ward CVCs were associated with higher rates of staphylococcal isolation (=0.01. A similar pattern of organisms were cultured from CRBSI and culture positive CVCs. The consistent relationship between CRBSI and culture positive CVCs, and similar pattern of causative organisms further supports an aetiological relationship between culture positive CVC tips and CRBSI, supporting the contention that CVC culture-positivity may be a useful surrogate marker for CRBSI rates.

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

  5. Bacterial Biofilms and Catheters: A Key to Understanding Bacterial Strategies in Catheter-Associated Urinary Tract Infection

    Directory of Open Access Journals (Sweden)

    J Curtis Nickel

    1992-01-01

    Full Text Available Despite major technological improvements in catheter drainage systems, the indwelling Foley catheter remains the most common cause of nosocomial infection in medical practice. By approaching this common complicated urinary tract infection from the perspective of the biofilm strategy bacteria appear to use to overcome obstacles to produce bacteriuria, one appreciates a new understanding of these infections. An adherent biofilm of bacteria in their secretory products ascends the luminal and external surface of the catheter and drainage system from a contaminated drainage spigot or urethral meatus into the bladder. If the intraluminal route of bacterial ascent is delayed by strict sterile closed drainage or addition of internal modifications to the system, the extraluminal or urethral route assumes greater importance in the development of bacteriuria, but takes significantly longer. Bacterial growth within these thick coherent biofilms confers a large measure of relative resistance to antibiotics even though the individual bacterium remains sensitive, thus accounting for the failure of antibiotic therapy. With disruption of the protective mucous layer of the bladder by mechanical irritation, the bacteria colonizing the catheter can adhere to the bladder’s mucosal surface and cause infection. An appreciation of the role of bacterial biofilms in these infections should suggest future directions for research that may ultimately reduce the risk of catheter-associated infection.

    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.

    Accurate diagnosis of catheter-related bloodstream infection (CRBSI) is mandatory for hospital infection control. Peripherally inserted central venous catheters (PICCs) are widely used in intensive care units, but studies about procedures for detection of colonization are scarce in neonates. We sequentially processed 372 PICCs by 2 methods, first by the standard roll-plate (RP) technique and then by rubbing catheters on a blood agar plate after being longitudinally split (LS). With both techniques, we detected 133 colonized PICCs. Ninety-four events of CRBSI were diagnosed. The sensitivity, specificity, positive predictive value, and negative predictive value for detection of CRBSI were 58.5%, 92.8%, 73.3%, and 86.9%, respectively, for RP technique and 96.8%, 88.5%, 74.0%, and 98.8%, respectively, for LS technique. The LS technique increased the proportion of detected CRBSI by 38.3%. Neonatal PICC tips should be cultured after cutting them open. This technique is simple and sensitive to detect catheter colonization and also to diagnose CRBSI.

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

    Indwelling urinary catheters are commonly used in the management of hospitalized patients. Candida can adhere to the device surface and propagate as a biofilm. These Candida biofilm communities differ from free-floating Candida, exhibiting high tolerance to antifungal therapy. The significance of catheter-associated candiduria is often unclear, and treatment may be problematic considering the biofilm drug-resistant phenotype. Here we describe a rodent model for the study of urinary catheter-associated Candida albicans biofilm infection that mimics this common process in patients. In the setting of a functioning, indwelling urinary catheter in a rat, Candida proliferated as a biofilm on the device surface. Characteristic biofilm architecture was observed, including adherent, filamentous cells embedded in an extracellular matrix. Similar to what occurs in human patients, animals with this infection developed candiduria and pyuria. Infection progressed to cystitis, and a biofilmlike covering was observed over the bladder surface. Furthermore, large numbers of C. albicans cells were dispersed into the urine from either the catheter or bladder wall biofilm over the infection period. We successfully utilized the model to test the efficacy of antifungals, analyze transcriptional patterns, and examine the phenotype of a genetic mutant. The model should be useful for future investigations involving the pathogenesis, diagnosis, therapy, prevention, and drug resistance of Candida biofilms in the urinary tract.

    Semiquantitative (Maki and quantitative (Brun- Buisson culture techniques were employed in the diagnosis of catheter-related bloodstream infections (CRBSI in patients who have a short-term central venous catheter (inserted for 30 days. The diagnosis of CRBSI was based on the results of semiquantitative and quantitative culture of material from the removed catheters. Catheter tips (118 from 100 patients were evaluated by both methods. Semiquantitative analysis revealed 34 catheters (28.8% colonized by ≥15 colonyforming units (cfu, while quantitative cultures (34 catheters, 28.8% showed the growth of ≥103 cfu/mL. Bacteremia was confirmed in four patients by isolating microorganisms of identical species from both catheters and blood samples. Using the semiquantitative culture technique on short-term central venous catheter tips, we have shown that with a cut-off level of ≥15 cfu, the technique had 100.0% sensitivity, specificity of 68.4%, 25.0% positive predictive value (PPV and 100.0% negative predictive value (NPV, efficiency of 71.4% and a prevalence of 9.5%. The quantitative method, with a cut-off limit of ≥103 cfu/mL, gave identical values: the sensitivity was 100.0%, specificity 68.4%, positive predictive value (PPV 25.0%, negative predictive value (NPV 100.0%, efficiency 71.4% and prevalence 9.5%. We concluded that the semiquantitative and quantitative culture methods, evaluated in parallel, for the first time in Brazil, have similar sensitivity and specificity.

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

    Full Text Available Background Bloodstream infection (BSI is one of the significant causes of morbidity and mortality encountered in a neonatal intensive care unit (NICU, especially in developing countries. Despite the implementation of infection control practices, such as strict hand hygiene, the BSI rate in our hospital is still high. The use of a closed catheter access system to reduce BSI related to intravascular catheter has hitherto never been evaluated in our hospital. Objective To determine the effects of closed catheter access system implementation in reducing the BSI rate in preterm neonates with low birth weight.Methods Randomized clinical trial was conducted on 60 low birth weight preterm infants hospitalized in the neonatal unit at Cipto Mangunkusumo Hospital, Jakarta, Indonesia from June to September, 2013. Randomized subjects either received a closed or non-closed catheter access system. Subjects were monitored for 2 weeks for the development of BSI based on clinical signs, abnormal infection parameters, and blood culture. Results Closed catheter access system implementation gave a protective effect towards the occurrence of culture-proven BSI (relative risk 0.095, 95% CI 0.011 to 0.85, p=0.026. Risk of culture-proven BSI in the control group was 10.545 (95% CI 1.227 to 90.662, p=0.026. BSI occurred in 75% of neonates without risk factors of infection in the control group compared to none in the study group.Conclusions The use of a closed catheter access system reduced the BSI in low birth weight preterm infants. Choosing the right device design, proper disinfection of device and appropriate frequency of connector change should be done simultaneously.

    Full Text Available Introduction. Catheter-associated urinary tract infections (CAUTI are the most common nosocomial infections. The worldwide data show the increasing resistance to conventional antibiotics among urinary tract pathogens. Aim. To evaluate the adequacy of initial antimicrobial therapy in relation to the antimicrobial resistance of pathogens responsible for CAUTI in Clinical Center of Banja Luka. Methods. A retrospective study on major causes of CAUTI, antibiotic resistance and treatment principles was conducted at four departments of the Clinical Center of Banja Luka from January 1st, 2000 to April 1st, 2003. Results. The results showed that 265 patients had developed CAUTI. The seven most commonly isolated microorganisms were, in descending order: E. coli (31.0%, Pseudomonas aeruginosa (13.8%, Proteus mirabilis (12.9%, Gr. Klebsiella-Enterobacter (12.3%, Enterococcus spp. (5.2%, Pseudomonas spp. (4.3%, Serratia spp. (4.0%. The most common pathogens were highly resistant to ampicillin (64−100%, gentamycin (63−100%, and trimethoprim-sulfamethoxazole (68−100%, while some bacterias, like Pseudomonas aeruginosa and Serratia spp. showed rates of ciprofloxacin resistance as high as 42.8% and 72.7%, respectively. In 55.5% of the cases, the initial antibiotic therapy was inadequate, and was corrected latter on. There were no standard therapeutic protocols for this type of nosocomial infections. Conclusion. The results of this study emphasized an urgency of the prevention and introduction of clinical protocols for better management of CAUTI. Treatment principles should better correspond to the antibiotic sensitivity of uropathogens.

Catheter associated urinary tract infections are some of the most common hospital infections and cost the health care system billions of dollars. Early removal is one of the mainstays of prevention as 100% of catheters become colonized. Patients with ureteral stents are also affected by infection and antibiotic therapy alone may not be the answer. We will review the current evidence on how to prevent infections of urinary biomaterials by using different coatings, new materials, and drug eluting technologies to decrease infection rates of ureteral stents and catheters.

    Preventing catheter-associated urinary tract infections is in the forefront of health care quality. However, nurse and physician engagement is a common barrier in infection prevention efforts. After implementation of a multidisciplinary catheter-associated urinary tract infection (CAUTI) prevention campaign, we studied the impact of our campaign and showed its association with reducing the CAUTI rate and catheter utilization and the positive effect on health care workers' engagement and perspectives. CAUTI prevention campaigns can lead to lower infection rates and change health care workers' perspective.

    Bacillus cereus, an opportunistic pathogen, can cause fatal infection. However, B. cereus bloodstream infections (BSIs) have not been well characterised. From 2008 to 2013, B. cereus isolates from all of the specimens and patients with B. cereus BSIs were identified. Environmental samples were collected to detect B. cereus contamination. We also characterised the clinical presentation of B. cereus BSI through analyses of risk factors for BSI and mortality. A total of 217 clinical B. cereus isolates was detected. Fifty-one patients with nosocomial infections were diagnosed as B. cereus BSI, and 37 had contaminated blood cultures. The number of B. cereus isolates and BSI patients was significantly greater from June to September than from January to April (4.9 vs. 1.5 per month and 1.2 vs. 0.2, respectively). All BSIs were nosocomial and related to central or peripheral vascular catheter. Urinary catheter [odds ratio (OR) 6.93, 95% confidence interval (CI) 2.40-20.0] was the independent risk factor associated with BSI patients when compared to patients regarded as contaminated. In-hospital mortality among BSI patients was 20% and was associated with urinary catheter (OR 34.7, 95 % CI 1.89-63.6) and higher Charlson index (OR 1.99, 95 % CI 1.26-3.12). The number of B. cereus isolates and BSI increased during summer. Inpatients with indwelling vascular or urinary catheters should be carefully monitored for potential B. cereus BSIs.

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

    Biofilm development in urinary tract catheters is an often underestimated problem. However, this form of infection leads to high mortality rates and causes significant costs in health care. Therefore, it is important to analyze these biofilms and establish avoiding strategies. In this study a continuous flow-through system for the cultivation of biofilms under catheter-associated urinary tract infection conditions was established and validated. The in vitro urinary tract catheter system implies the composition of urine (artificial urine medium), the mean volume of urine of adults (1 mL min(-1)), the frequently used silicone catheter (foley silicon catheter) as well as the infection with uropathogenic microorganisms like Pseudomonas aeruginosa. Three clinical isolates from urine of catheterized patients were chosen due to their ability to form biofilms, their mobility and their cell surface hydrophobicity. As reference strain P. aeruginosa PA14 has been used. Characteristic parameters as biofilm thickness, specific biofilm growth rate and substrate consumption were observed. Biofilm thicknesses varied from 105±16 μm up to 246±67 μm for the different isolates. The specific biofilm growth rate could be determined with a non invasive optical biomass sensor. This sensor allows online monitoring of the biofilm growth in the progress of the cultivation.

    Deep brain stimulation (DBS) has become a reliable and effective treatment for many disorders. However, the risk of long-term hardware-related complications is notable, and most concerning is hardware-related infections. Given the risk of hardware removal in the setting of infection, we retrospectively examined the implementation of a novel technique using antibiotic covered catheter protection of DBS leads after infection. The effect on hardware salvage and ease of reimplantation of the DBS extension and implantable pulse generator (IPG) was examined. A total of nine (9%) out of 100 DBS patients met the inclusion criteria with 11 DBS hardware-related infections at either the frontal, parietal, or IPG sites, from June 2003 to November 2010, at our institution. Subsequent to the initial patient in the series, a total of eight patients had placement of a short segment (approx. 4 cm long) of antibiotic impregnated catheter (Bactiseal, Codman, Johnson & Johnson, Raynham, MA, USA) over the distal end of the DBS leads at the parietal incision. Seven of these eight patients presented with pus and deep tissue infections around the hardware at either the frontal, parietal, or chest incisions. In seven of these eight patients (87.5%) we were able to protect and salvage their DBS leads without need for removal. In conclusion, this novel technique provides a simple reimplantation operation, with a decreased risk of DBS lead damage. It may improve the preservation of DBS leads when hardware infection occurs, is inexpensive, and confers no additional risks to patients.

    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.

    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.

    More than 40% of nosocomial infections are those of the urinary tract, most of these occurring in catheterized patients. Bacterial colonization of the urinary tract and catheters results not only in infection, but also various complications, such as blockage of catheters with crystalline deposits of bacterial origin, generation of gravels and pyelonephritis. The diversity of the biofilm microbial community increases with duration of catheter emplacement. One of the most important pathogens in this regard is Proteus mirabilis. The aims of this study were to identify and assess particular virulence factors present in catheter-associated urinary tract infection (CAUTI) isolates, their correlation and linkages: three types of motility (swarming, swimming and twitching), the ability to swarm over urinary catheters, biofilm production in two types of media, urease production and adherence of bacterial cells to various types of urinary tract catheters. We examined 102 CAUTI isolates and 50 isolates taken from stool samples of healthy people. Among the microorganisms isolated from urinary catheters, significant differences were found in biofilm-forming ability and the swarming motility. In comparison with the control group, the microorganisms isolated from urinary catheters showed a wider spectrum of virulence factors. The virulence factors (twitching motility, swimming motility, swarming over various types of catheters and biofilm formation) were also more intensively expressed.

    related to central venous catheters (CVC are complications with a high prevalence and possible serious consequences. Administration of total parenteral nutrition (TPN is a risk factor, although the information available for these patients and conventional inpatient units is scarce. Objective: To determine the rate of catheter-related bacteremia (CRB in patients with TPN and to identify possible relationships with administration route or place of insertion, to determinate the current situation and identify possible preventive measures. Method: Prospective-observational study of 13 months. All adult patients who received TPN were included. Infection rate used was the CRB per 1,000 days of CVC. Results: 176 CVC were registered in 159 patients. In 47% of CVC, vein access was jugular vein, despite being a location of greatest risk of infection. In critically ill patients, which followed a zero bacteremia project, there was no cases of infection. In other patients, bacteremia rate was 13.10 per 1,000 days of CVC. The average time elapsed between catheter insertion and infection was 11 days (range: 4-22 and the most frequent species were S. epidermidis (38% and S. hominis (19%. Discussion: In our environment there is a high rate of BRC in non-critical patients, with a high proportion of CVC in locations with higher risk of infection, despite not having found in the sample a higher rate of infection depending on the access route. Place of insertion, operating room face ward, is related to a lower rate of BRC. Measures to standardize clinical practice may reduce its incidence. The zero bacteremia project is confirmed as a highly effective method.

    Health care associated infections, the fourth leading cause of disease in industrialised countries, are a major health issue. One part of this condition is based on the increasing insertion and implantation of prosthetic medical devices, since presence of a foreign body significantly reduces the number of bacteria required to produce infection. The most significant hospital-acquired infections, based on frequency and potential severity, are those related to procedures e.g. surgical site infections and medical devices, including urinary tract infection in catheterized patients, pneumonia in patients intubated on a ventilator and bacteraemia related to intravascular catheter use. At least half of all cases of nosocomial infections are associated with medical devices.Modern medical and surgical practices have increasingly utilized implantable medical devices of various kinds. Such devices may be utilized only short-time or intermittently, for months, years or permanently. They improve the therapeutic outcome, save human lives and greatly enhance the quality of life of these patients. However, plastic devices are easily colonized with bacteria and fungi, able to be colonized by microorganisms at a rate of 0.5 cm per hour. A thick biofilm is formed within 24 hours on the entire surface of these plastic devices once inoculated even with a small initial number of bacteria.The aim of the present work is to review the current literature on causes, frequency and preventive measures against infections associated with intravascular devices, catheter-related urinary tract infection, ventilator-associated infection, and infections of other implantable medical devices. Raising awareness for infection associated with implanted medical devices, teaching and training skills of staff, and establishment of surveillance systems monitoring device-related infection seem to be the principal strategies used to achieve reduction and prevention of such infections.

    There are concerns about secondary extracorporeal membrane oxygenation (ECMO) catheter infections in bacteremic patients. We investigated the association between blood stream infection (BSI) and ECMO catheter colonization. From January 2012 to August 2014, 47 adults who received ECMO support were enrolled. The ECMO catheter tip was cultured at the end of the ECMO procedure. The enrolled patients were classified into two groups according to the presence of BSI during ECMO support and analyzed with respect to ECMO catheter colonization. Of 47 cases, BSI during ECMO was identified in 13 patients (27.7 %). ECMO catheter colonization was identified in 6 (46.2 %) patients in the BSI group and 3 (8.8 %) in the non-BSI group. BSI during ECMO support was independently associated with ECMO catheter colonization [odds ratio (OR) 5.55; 95 % confidence interval (CI) 1.00-30.73; p = 0.049]. The organisms colonizing ECMO catheters in the setting of primary BSI were predominantly Gram-positive cocci and Candida species. Acinetobacter baumannii was the most common colonizing pathogen in the setting of secondary BSI. All the organisms colonizing ECMO catheters were multi-drug resistant organisms, including methicillin-resistant S. aureus, Candida glabrata, and carbapenem-resistant A. baumannii. ECMO catheters may become contaminated with multi-drug resistant pathogens in the presence of BSI. Therefore, ECMO should be applied cautiously in septic patients with bacteremia caused by multi-drug resistant pathogens.

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

    Full Text Available Background: Catheter-associated urinary tract infection (CAUTI is the most common nosocomial infection. The etiological agents of which may be varied. Advancing age, debilitation, diabetes mellitus, duration of catheterization are the risk factors. Complications include prostatitis, epididymitis, cystitis, pyelonephritis and septicemia in high-risk patients, adding to hospitalization and morbidity. With this background the present study was undertaken Objectives: (1 To identify microbial pathogens associated with urinary tract infection (UTI in catheterized patients from Intensive Care Units (ICU (2 to determine the susceptibility pattern of these isolates to antimicrobial agents (3 to determine the effect of days of catheterization and UTI. Materials and Methods: Consecutive urine samples of 345 catheterized patients admitted in ICUs were included in the study. They were processed by standard microbiological procedures. Isolated organisms were speciated, and antibiotic susceptibility performed as per standard guidelines. Results: From the 345 urine samples of catheterized patients, 205 showed no growth and were found to be sterile. Bacterial growth was seen in 69 patients and fungal growth in 50 patients. Among the bacterial isolates, Escherichia coli were isolated in 39, followed by Klebsiella spp. 14. The other isolates included Pseudomonas spp., Group D streptococci and methicillin-resistant Staphylococcus aureus. In the fungal isolates, Candida glabrata was the most common isolate. High resistance was seen among Klebsiella isolates (nalidixic acid-86% and cefotaxime-86%. Conclusion: Development of CAUTI is common in critically ill patients. Emphasis should be placed on good catheter management and reducing the duration of catheterization rather than prophylaxis in order to reduce the incidence of catheter-related UTI. Culture and susceptibility testing play a vital role in the management if UTI occurs.

    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 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.

    目的 评价抗感染中心静脉导管在减少重症监护病房(ICU)患者导管相关性感染(CRI)中的作用.方法 将248例在ICU留置中心静脉导管的患者随机分成普通中心静脉导管组(对照组120例)和抗感染中心静脉导管组(抗感染组128例),观察两组CRI的发生率和病原菌分布情况.结果 抗感染组的CRI发生率明显低于对照组(6.3%vs14.2%),差异有统计学意义(P<0.05).CRI的病原菌为金黄色葡萄球菌、鲍曼不动杆菌、阴沟肠杆菌、肠球菌、肺炎克雷伯菌和白色念珠菌,但两组患者CRI病原菌分布比较,差异无统计学意义(P>0.05).结论 抗感染中心静脉导管可明显降低ICU患者CRI的发生率.%Objective To evaluate the effect of reducing intravenous catheter-ralated infection (CRT) using antiseptic impregnated central venous catheter in patients in intensive care unit (ICU). Methods 248 patients treated in ICU who needed intravascular catheterization were randomly divided into the control group (120 cases, treated with ordinary central venous catheter) and the antiseptic group (128 cases, treated with antiseptic impregnated central venous catheter). The incidence of CRI and pathogenic distribution were observed. Results The incidence of CRI in the antiseptic group was significantly lower than that of the control group (6.3% vs 14.2%, P<0.05). The pathogens of CRI were Staphytococcus aureus, Acmetabactor baumarwiii, E. Cloacae, entemcoccus, Klebsiella pneumonias and Candida albicans. Pathogenic distribution between the two groups showed no statistically significant difference (PX).O5). Conclusion Antiseptic impregnated central venous catheter can obviously reduce the incidence of CRI in patients in ICU.

    An agar subcutaneous infection model (agar model), which simulates the rat subcutaneous infection model (rat model), was developed to assess the ability of antimicrobial catheters to resist microbial colonization. The catheters were implanted in the agar and rat models and the insertion sites were infected immediately or on day 7, 14 or 21 post-implantation. The catheters implanted in the agar model were transferred to fresh media one day before infection on day 7, 14 or 21. The efficacy of chlorhexidine and silver sulfadiazine impregnated (CS) catheters, CS catheters with higher levels of chlorhexidine (CS+ catheters), minocycline-rifampicin (MR) catheters and silver catheters against Staphylococcus aureus and rifampicin-resistant Staphylococcus epidermidis RIF-r2 was compared in the agar and rat models. No significant difference in the adherence or the drug release was found between the in vitro and in vivo models. In both models, CS+ and MR catheters were effective against S. aureus even when infected on day 14, whereas CS catheters were colonized when challenged on day 7. CS+ catheters were effective against S. epidermidis RIF-r2, whereas MR catheters showed adherence when infected on day 7. CS+ catheters prevented colonization of all the organisms including, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Candida albicans in the agar model, whereas MR catheters were effective only against S. aureus and S. epidermidis strains. Silver catheters were ineffective against all the organisms. The agar model may be used to predict the in vivo efficacy of antimicrobial catheters against various pathogens.

    Animal models are valuable tools for investigating the in vivo pathogenesis of Staphylococcus epidermidis infections. Here, we present the procedure for generating a central nervous system catheter-associated infection in a mouse, to model the central nervous system shunt infections that frequently complicate the treatment of hydrocephalus in humans. This model uses stereotactic guidance to place silicone catheters, pre-coated with S. epidermidis, into the lateral ventricles of mice. This results in a catheter-associated infection in the brain, with concomitant illness and inflammation. This animal model is a valuable tool for evaluating the pathogenesis of bacterial infection in the central nervous system, the immune response to these infections and potential treatment options.

    Urinary catheters are widely used for hospitalized patients and are often associated with high rates of urinary tract infection. We evaluated in vitro the antiadherence activity of a novel antiseptic Gendine-coated urinary catheter against several multidrug-resistant bacteria. Gendine-coated urinary catheters were compared to silver hydrogel-coated Foley catheters and uncoated catheters. Bacterial biofilm formation was assessed by quantitative culture and scanning electron microscopy. These data were further correlated to an in vivo rabbit model. We challenged 31 rabbits daily for 4 days by inoculating the urethral meatus with 1.0 x 10(9) CFU streptomycin-resistant Escherichia coli per day. In vitro, Gendine-coated urinary catheters reduced the CFU of all organisms tested for biofilm adherence compared with uncoated and silver hydrogel-coated catheters (P < 0.004). Scanning electron microscopy analysis showed that a thick biofilm overlaid the control catheter and the silver hydrogel-coated catheters but not the Gendine-coated urinary catheter. Similar results were found with the rabbit model. Bacteriuria was present in 60% of rabbits with uncoated catheters and 71% of those with silver hydrogel-coated catheters (P < 0.01) but not in those with Gendine-coated urinary catheters. No rabbits with Gendine-coated urinary catheters had invasive bladder infections. Histopathologic assessment revealed no differences in toxicity or staining. Gendine-coated urinary catheters were more efficacious in preventing catheter-associated colonization and urinary tract infections than were silver hydrogel-coated Foley catheters and uncoated catheters.

    Objective To investigate the risk factors of elderly patients with central vein catheter related fungal infection in intensive care units, and to provide basis for earlier empirical antifungal treatment. Methods 47 elderly patients who admitted into ICU from August 2008 to August 2011 and who were diagnosed as central vein catheter related infection were retrospectively analyzed. All the patients were divided into fungal infection group and bacterial infection group, and the risk factors were analyzed. Results Compared with bacterial infection group, patients in fungal infection group had significantly longer catheter indwelling time, significantly more Candida parasitism and more application of broad - spectrum antibiotics ≥7 days, significantly higher APACHE II scores and significantly higher usage rate of antibacterial catheters ( P < 0. 05 ) . Multivariate logistic regression analysis showed that Candida parasitism, high APACHE II scores and application of broad - spectrum antibiotics ≥7 days were independent risk factors of central vein catheter related fungal infection. Conclusion Candida parasitism, high APACHE Ⅱ scores, using broad - spectrum antibiotics ≥ 7 days were independent risk factors of central vein catheter related fungi infection. This can guide the usage of central venous catheters and earlier empirical antifungal treatment.%目的 探讨重症监护病房(ICU)老年患者导管相关性真菌感染的危险因素,为早期经验性治疗提供依据.方法 回顾性调查2008年8月-2011年8月在我科住院并确诊为导管相关性血行性感染(CLABSI)的患者共47例,分为真菌感染组和细菌感染组,分析其危险因素.结果 真菌感染组较细菌感染组导管留置时间明显延长,念珠菌定植、应用广谱抗生素≥7 d患者明显增多,确诊感染当天急性生理与慢性健康状况评分Ⅱ(APACHEⅡ评分)明显升高,抗菌导管使用率明显升高,差异均有统计学意义(P<0.05).多因

    Bacillus cereus, an opportunistic pathogen, can cause fatal infection. However, B. cereus bloodstream infections (BSIs) have not been well characterised. From 2008 to 2013, B. cereus isolates from all of the specimens and patients with B. cereus BSIs were identified. Environmental samples were collected to detect B. cereus contamination. We also characterised the clinical presentation of B. cereus BSI through analyses of risk factors for BSI and mortality. A total of 143 clinical B. cereus isolates was detected. Fifty-one patients with nosocomial infections were diagnosed as B. cereus BSI, and 37 had contaminated blood cultures. The number of B. cereus isolates and BSI patients was significantly greater from June to September than from January to April (3.4 vs. 1.0 per month and 1.4 vs. 0.2, respectively). All BSIs were nosocomial and related to central or peripheral vascular catheter. Urinary catheter [odds ratio (OR) 6.93, 95 % confidence interval (CI) 2.40-20.0] was the independent risk factor associated with BSI patients when compared to patients regarded as contaminated. In-hospital mortality among BSI patients was 20 % and was associated with urinary catheter (OR 12.3, 95 % CI 0.67-225, p=0.045) and higher Charlson index (OR 1.99, 95 % CI 1.26-3.12). The number of B. cereus isolates and BSI increased during summer. Inpatients with indwelling vascular or urinary catheters should be carefully monitored for potential B. cereus BSIs.

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

    Two antiseptic solutions (iodine polyvidone and chlorhexidine) were compared-in a prospective non-randomized study including 294 parturient women. This study aimed to assess their efficacy against infections through epidural catheters. All catheters were subsequently cultivated. Cultures were significantly positive in 3% of cases after iodine polyvidone and 1% after chlorhexidine decontamination (not significant). No clinical or biological infections were detected. Notwithstanding some apparently unavoidable but moderate contaminations, prevention of infections post epidural analgesia depends principally on a complete adherence to asepsia rules.

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

    Access-related infections (ARIs), such as exit-site infections, tunnel infections, bacteremia, fungemia and peritonitis, are the Achilles' heel of dialysis, and contribute significantly to morbidity, mortality and excess healthcare costs in hemodialysis and peritoneal dialysis patient populations. Despite international guidelines recommending the avoidance of catheters for hemodialysis access, hospital admissions for vascular ARIs have doubled in the last decade. Moreover, repeated use of antibiotics to treat ARIs has been associated with the selection of multiresistant organisms, such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci. ARIs result from direct inoculation of skin organisms during access cannulation/connection, migration of skin organisms along dialysis catheters into the bloodstream or peritoneal cavity, or contamination and colonization of catheter lumens with subsequent biofilm formation. This paper will review the epidemiology, pathogenesis and prevention of ARIs. It will focus specifically on randomized, controlled trial evidence in relation to the safety and efficacy of aseptic techniques, nasal eradication of S. aureus, oral antimicrobial prophylaxis, topical antimicrobial prophylaxis (including disinfectants, antibiotics and antibacterial honey), antimicrobial catheter lock solutions (including gentamicin, citrate and ethanol), antimicrobial-impregnated catheters, catheter design (straight vs coiled, single vs double cuff), peritoneal dialysis catheter connectology, catheter insertion technique, germicidal devices, vaccines and preinsertion antibiotic prophylaxis.

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

    Full Text Available Abstract Background Tunnelled central venous dialysis catheter use is significantly limited by the occurrence of catheter-related infections. This randomised controlled trial assessed the efficacy of a 48 hour 70% ethanol lock vs heparin locks in prolonging the time to the first episode of catheter related blood stream infection (CRBSI. Methods Patients undergoing haemodialysis (HD via a tunnelled catheter were randomised 1:1 to once per week ethanol locks (with two heparin locks between other dialysis sessions vs thrice per week heparin locks. Results Observed catheter days in the heparin (n=24 and ethanol (n=25 groups were 1814 and 3614 respectively. CRBSI occurred at a rate of 0.85 vs. 0.28 per 1000 catheter days in the heparin vs ethanol group by intention to treat analysis (incident rate ratio (IRR for ethanol vs. heparin 0.17; 95%CI 0.02-1.63; p=0.12.

    Full Text Available INTRODUCTION: Catheter associated Urinary Tract Infection (UTI represent the most common type of nosocomial infection and is a major health concern due to its complications and frequent recurrence. Among the nosocomial infections UTI contributes a major part. About 80% of nosocomial UTI are associated with using indwelling urinary catheters and most of them are asymptomatic. Only 5% of them develop s symptomatic UTI which leads to development of complications like bacteremia & pyelonephritis. MATERIALS AND METHODS: In th e present study a random collection of 100 urine samples from different clinical “groups ˮ like surgery, urology, AMCU, Ob stetrics & Gynecology patients with indwelling urinary catheter of different durations of catheter stay. Organisms isolated in culture, biochemical c haracterization, and antibiotic susceptibility was done. RESULTS: Among the samples tested 41/100 (41% showed culture positivity. within them surgery patients were 40.90% (18/41 , Urology accounted for, 71.42 % (20/28, in AMCU patients 20% (2/10, with more than 3 days of duration of catheter stay and in Obs & Gyn department showed 0 culture positivity. The predominant organism isolated is pseudomonas aeruginosa (34.2%, followed by Escherichia coli (22%, enterococci (12.19%, Klebsiella (12.19% and Ca ndida 19.5%. Among GNB 90% showed ESBL production, 10% ß - lactam inhibitors resistance, 90% quinolones resistant, 50% resistant to amikacin, 100% to gentamycin was o bserved. CONCLUSION: Incidence of bacteriuria in patients with indwelling urinary catheters is 41 %. Onset of bacteriuria is as early as on 3 rd day of catheterization, and gradually increases with duration of stay, technique of insertion and daily catheter care done. Pseudomonas aeruginosa and Escherichia coli are common organisms isolated. Use o f prophylactic antibiotics without doing culture, and antibiotic susceptibility testing leads to development of drug resistant organisms. So, active

    Staphylococcus aureus nasal carriers undergoing hemodialysis (HD) through tunneled cuffed catheters (TCCs) form a high-risk group for the development of catheter-related bloodstream infections (CRBSI) and ensuing morbidity. The efficacy of antibiotic-locks on the outcomes of TCCs among S. aureus nasal carriers has not been studied earlier. Persistent nasal carriage was defined by two or more positive cultures for methicillin-susceptible (MSSA) or methicillin-resistant (MRSA) S. aureus of five standardized nasal swabs taken from all the participants dialyzed at a large out-patient HD center affiliated to a tertiary care hospital. Of 218 participants, 82 S. aureus nasal carriers dialyzed through TCCs (n = 88) were identified through April 2005 to March 2006 and randomized to two groups. Group I comprised of 39 nasal carriers who had TCCs (n = 41) "locked" with cefotaxime/heparin while group II included 43 patients with TCCs (n = 47) filled with standard heparin. The CRBSI incidence and TCC survival at 365 days were statistically compared between the two groups. A significantly lower CRBSI incidence (1.47 vs. 3.44/1000 catheter-days, P cefotaxime group compared with the standard heparin group. However, no significant difference in MRSA-associated CRBSI incidence was observed between the two groups. Cefotaxime-heparin "locks" effectively reduced CRBSI-incidence associated with gram-positive cocci, including MSSA, among S. aureus nasal carriers. There remains a compelling requirement for antibiotic-locks effective against MRSA.

    Full Text Available Central venous catheterization is a common diagnostic and therapeutic procedure in modern clinical practice. Pseudoaneurysms of the subclavian artery are rare and usually occur immediately after the causative event, whether the cause was trauma or a medical procedure. Here we report the rare case of a 71-year-old woman with delayed presentation of catheter-related subclavian pseudoaneurysm. The patient was treated for aspiration pneumonia with respiratory failure in another hospital. The patient's chest wall swelling began two weeks after the initial catheterization in the other hospital, probably because of slow leakage of blood from the injured subclavian artery caused by incomplete compression of the puncture site and uremic coagulopathy. She was successfully treated with ultrasound-guided thrombin and angiography-guided histoacryl injection without stent insertion or surgery. Her condition improved, and she was discharged to her home.

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

    Full Text Available La nutrición parenteral domiciliaria (NPD es una modalidad de soporte nutricional que permite la administración de las bolsas de nutrición parenteral en el propio domicilio del enfermo. Desde su utilización a finales de los años 60, este tratamiento ha permitido mantener con vida a pacientes con fallo intestinal que previamente estaban destinados a la muerte. En nuestro país la utilización de este tratamiento es de 2,15 pacientes/ millón de habitantes. Según los datos de NADYA las infecciones del catéter suponen el 50% de todas las complicaciones relacionadas con la NPD. En las series con mayor número de pacientes las tasas de infección son de 0,5-2 infecciones/1000 días o de 0,3-0,5 infecciones/paciente/ año. La mayoría de ellas están producidas por microorganismos gram positivos que migran desde la piel o desde las conexiones del catéter hasta la punta del mismo. El diagnóstico de estas infecciones se realiza con datos clínicos y con diferentes tipos de cultivos microbiológicos. En el tratamiento de estas infecciones es importante intentar mantener el catéter, administrando los antibióticos a través del mismo de forma convencional o bien mediante la técnica del sellado con antimicrobianos.Hom parenteral nutrition (HPN is a nutritional support modality that allows for the supply of parenteral nutrition bags to the patient's home.

    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

    Catheter associated urinary tract infections (CAUTIs) put an unnecessary burden on patients and health care systems. The purpose of this integrative review was to examine existing evidence on preventative interventions and protocols currently implemented in intensive care units (ICUs) and the impact they have on CAUTI rates and patient outcomes. This review analysed 14 research articles obtained from electronic databases and included adult patients with urinary catheters in an ICU setting. Evidence demonstrated interventions that included criteria for catheter use, daily review of catheter necessity and discontinuation of catheter prior to day seven were successful in decreasing CAUTI rates. This review provides a scientific basis for the effectiveness of these interventions and protocols. Identification and use of interventions with the greatest positive impact on CAUTI rates are an asset to healthcare professional caring for patients with indwelling catheters and nurse clinicians developing policies.

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

    Catheter-associated urinary tract infection (CAUTI) represents one of the most common causes of morbidity and mortality. The resistance demonstrated by many microorganisms to conventional antibiotic therapies and the increasing health-care costs have recently encouraged the definition of alternative preventive strategies, which can have a positive effect in the management of infections. Antimicrobial urinary catheters have been developed through the photo-chemical deposition of silver coatings on the external and luminal surfaces. The substrates are exposed to ultraviolet radiation after impregnation into a silver-based solution, thus inducing the in situ synthesis of silver particles. The effect of the surface treatment on the material was investigated through scanning electron microscopy (SEM) and silver ion release measurements. The ability of microorganisms commonly associated with urinary tract infections was investigated in terms of bacterial viability, proliferation and biofilm development, using Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis as target organisms. The silver coatings demonstrated good distribution of silver particles to the substrate, and proved an effective antibacterial capability in simulated biological conditions. The low values of silver ion release demonstrated the optimum adhesion of the coating. The results indicated a good potential of silver-based antimicrobial materials for prevention of catheter-associated urinary tract infection.

    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.

    Full Text Available 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.

    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.

    ABSTRACT Gram-positive bacteria in the genus Enterococcus are a frequent cause of catheter-associated urinary tract infection (CAUTI), a disease whose treatment is increasingly challenged by multiantibiotic-resistant strains. We have recently shown that E. faecalis uses the Ebp pilus, a heteropolymeric surface fiber, to bind the host protein fibrinogen as a critical step in CAUTI pathogenesis. Fibrinogen is deposited on catheters due to catheter-induced inflammation and is recognized by the N-terminal domain of EbpA (EbpANTD), the Ebp pilus’s adhesin. In a murine model, vaccination with EbpANTD confers significant protection against CAUTI. Here, we explored the mechanism of protection using passive transfer of immune sera to show that antisera blocking EbpANTD-fibrinogen interactions not only is prophylactic but also can act therapeutically to reduce bacterial titers of an existing infection. Analysis of 55 clinical CAUTI, bloodstream, and gastrointestinal isolates, including E. faecalis, E. faecium, and vancomycin-resistant enterococci (VRE), revealed a diversity of levels of EbpA expression and fibrinogen-binding efficiency in vitro. Strikingly, analysis of 10 strains representative of fibrinogen-binding diversity demonstrated that, irrespective of EbpA levels, EbpANTD antibodies were universally protective. The results indicate that, despite diversity in levels of fibrinogen binding, strategies that target the disruption of EbpANTD-fibrinogen interactions have considerable promise for treatment of CAUTI.

  17. Impact of polymicrobial biofilms in catheter-associated urinary tract infections.

    2016-12-30

    Recent reports have demonstrated that most biofilms involved in catheter-associated urinary tract infections are polymicrobial communities, with pathogenic microorganisms (e.g. Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae) and uncommon microorganisms (e.g. Delftia tsuruhatensis, Achromobacter xylosoxidans) frequently co-inhabiting the same urinary catheter. However, little is known about the interactions that occur between different microorganisms and how they impact biofilm formation and infection outcome. This lack of knowledge affects CAUTIs management as uncommon bacteria action can, for instance, influence the rate at which pathogens adhere and grow, as well as affect the overall biofilm resistance to antibiotics. Another relevant aspect is the understanding of factors that drive a single pathogenic bacterium to become prevalent in a polymicrobial community and subsequently cause infection. In this review, a general overview about the IMDs-associated biofilm infections is provided, with an emphasis on the pathophysiology and the microbiome composition of CAUTIs. Based on the available literature, it is clear that more research about the microbiome interaction, mechanisms of biofilm formation and of antimicrobial tolerance of the polymicrobial consortium are required to better understand and treat these infections.

    Encrustations are the most frequent complications occurring with indwelling catheters and urine drainage systems. The conditions for bacterial infections, using synthetic urine and controlled contamination by Proteus vulgaris, were standardised by using an in vitro model. Crystal deposits on catheters were analysed by infra-red spectroscopy and scanning electron microscopy. The main components of deposits in all investigations were struvite (MgNH4PO4.6H2O) 60-70% and carbonate apatite (Ca10(PO4,CO3)6 (OH,CO3)2) 30-40%. Investigations as to the quality and quantity of encrustations confirmed the analysis. Irrigation treatment was carried out with physiological saline solution and citric acid solution (Suby G) to study and quantify the dissolution of crystal deposits. Regular irrigation with citric solution resulted in a 70% dissolution of encrustations and ensured free flow as ascertained by measuring flow rates.

    Full Text Available Candida lipolytica is weakly pathogenic yeast, which is rarely isolated from the blood. We recovered this species from repeated blood samples and in the central venous catheter in a debilitated pediatric patient of tubercular meningitis. Identity was established on the basis of colony morphology and sugar assimilation tests (ID 32C assimilation profile. The fungemia and associated fever subsided after the removal of catheter and amphotericin B therapy. The data suggest that though of low virulence and usually a contaminant, C. lipolytica is emerging yeast pathogen in cases of catheter-related candidemia. Pathogenicity is indicated by isolation from repeated samples as in our case. Intensive therapy is recommended in cases not resolving spontaneously or responding to removal of catheter alone.

    Proteus mirabilis is an enterobacterium that causes catheter-associated urinary tract infections (CAUTIs) due to its ability to colonize and form crystalline biofilms on the catheters surface. CAUTIs are very difficult to treat, since biofilm structures are highly tolerant to antibiotics. Phages have been used widely to control a diversity of bacterial species, however, a limited number of phages for P. mirabilis have been isolated and studied. Here we report the isolation of two novel virulent phages, the podovirus vB_PmiP_5460 and the myovirus vB_PmiM_5461, which are able to target, respectively, 16 of the 26 and all the Proteus strains tested in this study. Both phages have been characterized thoroughly and sequencing data revealed no traces of genes associated with lysogeny. To further evaluate the phages’ ability to prevent catheter’s colonization by Proteus, the phages adherence to silicone surfaces was assessed. Further tests in phage-coated catheters using a dynamic biofilm model simulating CAUTIs, have shown a significant reduction of P. mirabilis biofilm formation up to 168 h of catheterization. These results highlight the potential usefulness of the two isolated phages for the prevention of surface colonization by this bacterium. PMID:27446059

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

    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.

    Objective To assess the effect of prophylactic antibiotics in the prevention of catheter-related bloodstream infection ( CRBSI ) in newborn infants. Methods We searched the randomizedcontroller( RCT ) studies on prophylactic antibiotics to prevent catheter-related bloodstream infection ( CRBSI )in neonates from 1 January, 1990 to 30 April, 2012,and performed meta-analysis with results from homogenous studies using Rev Man 5. 0 software to assess the odds ratio ( OR ) and 95% confidence intervals (95% Cl). Results Six studies were included. A total of 270 cases were in the group of prophylactic antibiotics ( observation group ), and 272 cases were in the group without antibiotics ( control group ). Meta-analysis showed that the observation group had decreased incidence of CRBSI (OR=0.14, 95% CI: 0. 07 - 0. 29 ), and catheter colonization (OR =0.41, 95% CI: 0. 23 - 0. 71 ). Overall mortality rate, the incidence of intraventricular hemorrhage, necrotizing enterocolitis and antibiotic resistance were similar between the two groups. Subgroup analysis based on the different routes of prophylactic antibiotics showed that there were no statistically significant difference between intravenous antibiotics and antibiotics-heparin lock solution on the outcome. Conclusions Prophylactic intravenous antibiotics in neonates reduced the rate of CRBSI and catheter colonization. However, the overall mortality rate was unaffectd. So, the routine use of prophylactic intravenous antibiotics in neonates with deep venous catheters cannot be recommended. Prophylactic antibiotics-heparin lock solutions in neonates with a deep venous catheter reduced the incidence of CRBSI and catheter colonization. But the small sample size of the included studies and the lack of data on antibiotic resistance mandate further clinical trials with higher quality and larger scale to evaluate its effectiveness and safety.%目的 系统评价抗生素预防新生儿深静脉置管相关感染的价值.方法

However, apart from mechanical and thrombotic complications, there are also complications associated with biofilm development inside the catheters. These biofilms increase the cost of medical assistance and extend hospitalization. The most frequently involved micro-organisms in these infections are gram-positive cocci. Many efforts have been made to understand biofilm formation within the lumen catheters, and to resolve catheter-related infection once it has been established. Apart from systemic antibiotic treatment, the use of local catheter treatment (ie, antibiotic lock technique is widely employed. Many different antimicrobial options have been tested, with different outcomes, in clinical and in in vitro assays. The stability of antibiotic concentration in the lock solution once instilled inside the catheter lumen remains unresolved. To prevent infection, it is mandatory to perform hand hygiene before catheter insertion and manipulation, and to disinfect catheter hubs, connectors, and injection ports before accessing the catheter. At present, there are still unresolved questions regarding the best antimicrobial agent for catheter-related bloodstream infection treatment and the duration of concentration stability of the antibiotic solution within the lumen of the port.

    Catheter-Associated Urinary Tract Infection (CAUTI) is the most common nosocomial infection in the U.S. healthcare system. The obstruction of urine caused by confined air bubbles result in the development of urinary back-flow and stagnation, wherein microbial pathogens could multiply rapidly and colonization within catheters become commonplace. Infections can be prevented by aseptic insertion and the maintenance of a closed drainage system, keeping high infection control standards, and preventing back-flow from the catheter bag. The goal of this study is to assess the effectiveness of a simple, low cost, modification that may be implemented into current catheter designs to reduce the incidence of CAUTI. Using the principle of transmission of fluid-pressure and the Young-Laplace equation for capillary pressure difference, this research focuses on improving the liquid flow in the presence of confined bubbles to prevent stagnation and reflux of bacteria-ridden urine into the body. Preliminary experiments are performed on a variety of tubes with hydrophobic-coating the interior, as well as geometrically modifying the tubes. Proof-of-Concept Prototype tubes are used to represent the drainage system of the catheter structure.

    Full Text Available Abstract Background Septic thrombophlebitis is an iatrogenic life-threatening disease associated with use of central venous devices and intravenous (IV therapy. In cancer patients receiving chemotherapy, vein resection or surgical thrombectomy in large central venous lines is time-consuming, can delay administration of chemotherapy, and therefore can compromise tumor control. Experience with thrombolysis has been published for catheter-related thrombosis but for septic thrombosis, this experience is scarce. Results We describe three patients with cancer and septic thrombophlebitis of central veins caused by Staphylococcus aureus treated with catheter removal, thrombolysis, and intravenous (IV antibiotics. In our reported cases, an initial bolus of 250,000 international units (IU of streptokinase administered during the first h followed by an infusion of 20,000–40,000 IU/h for 24–36 h through a proximal peripheral vein was sufficient to dissolve the thrombus. After thrombolyisis and parenteral antibiotic for 4–6 weeks the septic thrombosis due to Staphylococcus aureus solved in all cases. No surgical procedure was needed, and potential placement of a catheter in the same vein was permitted. Conclusion Thrombolysis with streptokinase solved symptoms, cured infection, prevented embolus, and in all cases achieved complete thrombus lysis, avoiding permanent central-vein occlusion.

    Full Text Available 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. 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: Sonuçlarımız nakil hastalarında tünelli SVK komplikasyonlarının yönetilebilir olduğunu ve bu komplikasyonların nakil üzerine olumsuz bir etki yaratmadığını göstermektedir.

    Infection is a potentially serious complication of epidural analgesia and with an increase in its use in wards there is a necessity to demonstrate its safety. We aimed to compare the incidence of colonization of epidural catheters retained for short duration (for 48 h) postoperative analgesia in postanesthesia care unit and wards. It was a prospective observational study done in a tertiary care teaching public hospital over a period of 2 years and included 400 patients with 200 each belonged to two groups PACU and ward. We also studied epidural tip culture pattern, skin swab culture at the entry point of the catheter, their relation to each other and whether colonization is equivalent to infection. Data were analyzed using statistical software GraphPad. Overall positive tip culture was 6% (24), of them 7% (14) were from PACU and 5% (10) were from ward (P = 0.5285). Positive skin swab culture was 38% (150), of them 20% (80) were from PACU and 18% (70) were from ward (P = 0.3526). The relation between positive tip culture and positive skin swab culture in same patients is extremely significant showing a strong linear relationship (95% confidence interval = 0.1053–0.2289). The most common microorganism isolated was Staphylococcus epidermidis. No patient had signs of local or epidural infection. There is no difference in the incidence of epidural catheter tip culture and skin swab culture of patients from the general ward and PACU. Epidural analgesia can be administered safely for 48 h in general wards without added risk of infection. The presence of positive tip culture is not a predictor of epidural space infection, and colonization is not equivalent to infection; hence, routine culture is not needed. Bacterial migration from the skin along the epidural track is the most common mode of bacterial colonization; hence, strict asepsis is necessary. PMID:27076712

    Full Text Available Abstract Background Catheter-related bacteraemias (CRBs contribute significantly to morbidity, mortality and health care costs in dialysis populations. Despite international guidelines recommending avoidance of catheters for haemodialysis access, hospital admissions for CRBs have doubled in the last decade. The primary aim of the study is to determine whether weekly instillation of 70% ethanol prevents CRBs compared with standard heparin saline. Methods/design The study will follow a prospective, open-label, randomized controlled design. Inclusion criteria are adult patients with incident or prevalent tunneled intravenous dialysis catheters on three times weekly haemodialysis, with no current evidence of catheter infection and no personal, cultural or religious objection to ethanol use, who are on adequate contraception and are able to give informed consent. Patients will be randomized 1:1 to receive 3 mL of intravenous-grade 70% ethanol into each lumen of the catheter once a week and standard heparin locks for other dialysis days, or to receive heparin locks only. The primary outcome measure will be time to the first episode of CRB, which will be defined using standard objective criteria. Secondary outcomes will include adverse reactions, incidence of CRB caused by different pathogens, time to infection-related catheter removal, time to exit site infections and costs. Prospective power calculations indicate that the study will have 80% statistical power to detect a clinically significant increase in median infection-free survival from 200 days to 400 days if 56 patients are recruited into each arm. Discussion This investigator-initiated study has been designed to provide evidence to help nephrologists reduce the incidence of CRBs in haemodialysis patients with tunnelled intravenous catheters.

    Full Text Available Acremonium spp. are filamentous, cosmopolitan fungi commonly isolated from plant debris and soil. They are infrequent pathogens in humans. Acremonium fungemia has been reported in neutropenic patients associated with central venous catheters and in nonneutropenic patients receiving long-term total parenteral nutrition. TNF-α blockade is associated with fungal infections, but no Acremonium spp. infection had been reported up to the present. In this paper, we present a patient with ulcerative colitis who developed Acremonium kiliense fungemia associated with infliximab therapy while receiving total parenteral nutrition. The patient was successfully treated with voriconazole. Acremonium sp. infection must be suspected as another cause of fungal infection in patients under treatment with infliximab.

    Staphylococcus epidermidis is a pathogenic organism with increasing importance in total parenteral nutrition therapy. Strict asepsis during catheter insertion prolongs the interval free from Staphylococcus epidermidis infection. Staphylococcus epidermidis colonizes the catheter after migrating from the skin. For protection, we advise a long subcutaneous tunnel for all catheters that are to be indwelling for longer than three weeks. Prompt recatheterization of a patient with Staphylococcus epidermidis sepsis can result in hematogenous seeding of the new catheter and persistence of the infection. Catheter related Staphylococcus epidermidis sepsis has subsided after catheter withdrawal, and there is no need for antibiotic therapy provided that other prosthetic materials are not placed in the vascular tree. Immunologic status of the patients is not related to the frequency or severity of Staphylococcus epidermidis infections, or both.

    The well known negative effect of infection on nutrition causes the cycle 'infection-malnutrition-infection'. Prolonged parenteral nutrition requires central venous catheterization. Due to the possibility of 'catheter related sepsis' (CRS) catheters should be used correctly to avoid septic complications. A very high percentage of central venous catheters (CVC) removed because of presumed infections are not infected when culture is done. In some patients infections are successfully treated with antibiotics without catheter removal. Removal of the line is recommended when catheter-associated sepsis is suspected or proven, but not for the extremely ill preterm infant or when such removal may be impractical. A therapeutic protocol is suggested to avoid future canalizations in the neonate, sometimes in a critical situation. Current literature referring to CRS in the newborn infant is reviewed.

    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 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.

    Objective To determine the value of differential time to positivity ( DTTP ) of blood culture for the diagnosis of catheter-related bloodstream infection ( CRBSI ) in patients with solid tumors in intensive care unit ( ICU ). Methods A retrospective study was conducted. 615 pairs of peripheral vein blood cultures and instantaneous catheter tip blood culture of 615 patients admitted to ICU of Tianjin Medical University Cancer Institute and Hospital were collected from August 2011 to March 2014. The DTTP method and ( or ) semi quantitative culture of catheter tip were compared. CRBSI was diagnosed when both cultures were positive for the same microorganism and DTTP ≥2 hours ( 120 minutes ). The result of this procedure was compared with that of organism obtained using the semi quantitative culture of blood at catheter tip with≥15 cfu. Based on the clinical diagnosis, the reliability of two kinds of laboratory examination was compared for the diagnosis of CRBSI by plotting receiver operator characteristic curve ( ROC curve ). Results The result of 615 cases suspected of having CRBSI were analyzed during the study period. Of these, 440 episodes were excluded because cultures were negative for blood obtained through peripheral vein and central vein. Eight episodes were excluded because only peripheral vein blood culture was positive and 57 episodes were excluded because of only central vein blood culture was positive, 68 pairs of blood cultures were excluded due to the presence of multiple catheters and repeated blood withdrawals. Two cases of polymicrobial cultures were excluded from the final analysis due to the difficulty in determining the time of positive result for each individual microorganism. Ten cases in 42 cases of suspected cases of CRBSI were excluded from analysis because catheter was not removed, therefore culture from catheter tip could not be obtained. Using the DTTP method, 14 out of 17 CRBSI cases were diagnosed with DTTP≥120 minutes, while 3

    The purpose of this study was to evaluate retrospectively the safety and effectiveness of radiologically placed tunneled peritoneal catheter in palliation of malignant ascites. Between July 2005 and June 2009, 41 tunneled peritoneal catheters were placed under ultrasonographic and fluoroscopic guidance in 40 patients (mean age, 55 years; 22 women) who had symptomatic malignant ascites. No procedure related mortality was observed. Major complication occurred in one patient (2.5%) in the form of serious bacterial peritonitis that necessitated catheter removal. Minor complications such as minor bacterial peritonitis, catheter dislodgement, tunnel infection, and catheter blockage occurred in 11 patients (27.5%). The mean duration of survival after catheter placement was 11.8 weeks. All patients expired of their primary malignancies in the follow-up. Radiologically placed tunneled peritoneal catheter is safe and effective in palliation of symptomatic malignant ascites.

    2013-04-01

    Full Text Available [english] Device-associated infections comprise a significant proportion of all nosocomial infections. In this prospective, observational pilot study the incidence of infections in 89 peripheral venous catheters (PVCs was documented on a general surgical ward employing an infection data sheet developed by the Institute of Hygiene and Environmental Medicine, Greifswald in adherence to CDC standards for infections. 16 of 20 infections were documented during a four-week time period when medical students in the first four months of their practical year performed their compulsory rotation on the general surgical ward. Insufficient knowledge of adequate hygienic measures as well as non-compliance to aseptical procedural measures prior to and following insertion of a peripheral venous catheter are the assumed instigators of these infections. In order to ensure a uniform hygienic standard in the performance of applied procedures, it is essential that medical students during this practical year receive not only theoretical, but also hands-on schooling prior to initiation of their subsequent official residency.

RESULTS AND CONCLUSION:According to the predefined search strategy, 949 potential y relevant patent papers were screened out for further identification, and 23 papers referred to anti-infective catheters that were obviously eligible were included. The analyses showed that:(1) The antibacterial coating agents of the majority of papers were antibacterial agents of nano-inorganic metal cations, only four papers used antibiotic coated. (2) The drug-eluting catheters were mainly composite-coated. (3) The drug release modes from coating were mainly extended-release but release mechanism was not clarified. (4) The preparation process was chemical bond or ionic bond in one paper, blending methods in one paper, repeated electroplating in one paper, electrospinning technology in one paper, and physical impregnation methods in 12 papers (52.17%). (5) The antimicrobial mode was ultrasonic-antibacterial method in two patent papers, sterile sleeve in one paper, hydrophilic coating in one paper, catheter made by blending polymer material and anti-infective agents in one paper, drug coated films made by coating with antimicrobial drug liquid and drying process in 20 papers (82.61%). In conclusion, there have been no translational and applied clinical researches about the anti-infective urinary catheter, and the relevant researches were only at the laboratory level. The research methods of Chinese patent for anti-infective urinary catheter were limited, and need to be further improved.

    Candida lipolytica was recovered from the blood and the central venous catheter in a patient receiving allogeneic bone marrow transplantation. Two C. lipolytica strains from different geographical areas and the ATCC 9773 strain of C. lipolytica were used as controls. C. lipolytica was identified by standard methods. MICs indicated antifungal susceptibilities to amphotericin B, fluconazole, and itraconazole for all strains. In vitro testing and scanning electron microscopy showed that C. lipolytica was capable of producing large amounts of viscid slime material in glucose-containing solution, likely responsible for the ability of the yeast to adhere to catheter surfaces. Restriction fragment length polymorphisms revealed an identical profile for all clinical isolates, unrelated to those observed for the control strains. This finding suggested the absence of microevolutionary changes in the population of the infecting strain, despite the length of the sepsis and the potential selective pressure of amphotericin B, which had been administered to the patient for about 20 days. The genomic differences that emerged between the isolates and the control strains were indicative of a certain degree of genetic diversity between C. lipolytica isolates from different geographical areas.

    To evaluate the feasibility that a dilated right external jugular vein (EJV) could be a primary venous access site for large bore hemodialysis catheter placement. Between January 2008 and April 2009, a total of 173 hemodialysis catheters (14.5 F) were placed. Among them, we evaluated the clinical data of 42 patients who underwent placement through a dilated right EJV. We evaluated technical success, duration of catheterization in days, and the presence of complications. Technical success was achieved for 41 patients (98%). Catheter placement was unsuccessful in one patient due to narrowing of the EJV. The catheter dwell time ranged between 14 and 305 days (mean; 76 days, total catheter days: 3,111 days). A total of 26 hemodialysis catheters were removed due to complications (n=2) and termination of hemodialysis via the hemodialysis catheter (n=24). There was air embolization (n=1) and catheter kinking (n=3) during procedures and catheter related infections (n=2) during the follow-up period. The incidence of catheter related infection was 0.06 per 100 catheter days. No cases of catheter malfunction or symptomatic venous thrombosis were observed. We suggest that a dilated right EJV could be considered as a preferred primary route for hemodialysis catheter placement with easy access

    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

    Full Text Available [english] Aim: Catheter associated urinary tract infections (CAUTI are the most common hospital-acquired infection in ICUs. The aim of this study was to estimate the effectiveness of an intervention program by implementing urinary catheter bundle elements to reduce the CAUTI frequency in an ICU. Methods: The intervention study was conducted over a period of onths. During a pre-intervention phase, the base line catheter associated CAUTI incidence rates were determined and compared with the incidence rates during the post-intervention phase. The compliance of health care staff with urinary catheter bundle elements was also measured. The implemented CAUTI prevention bundle consisted of hand hygiene, wearing personal protective equipment, use of disposable gloves, cleansing of urethral meatus prior to catheter insertion using sterile saline, assessment of catheter need, aseptic urine sampling technique, and correct draining bag positioning.Results: During the study period, 55 out of 77 patients were diagnosed with a CAUTI. The mean CAUTI incidence rate for the pre-intervention period was 90.12/1,000 catheter days and for the post intervention phase 65.69/1,000 catheter days. The CAUTIs rate was inversely proportional to insertion bundle elements and maintenance bundle elements compliance rate. This negative relationship was statistically significant only with maintenance bundle elements (p=0.042 (r=–0.828. The compliance rate of the ICU nurses to the bundle elements was raised to 100% during the last 2 months of the post intervention phase.Conclusion: Increased compliance to recommended catheter associated urinary tract infections preventive practices reduced the incidence of CAUTI in an ICU unit. It is simple and effective and is recommended as a part of patient safety culture.

    Achromobacter xylosoxidans is a rare cause of bacteremia. Over a 2-week period, A. xylosoxidans subsp. xylosoxidans was isolated from blood cultures of four hemodialysis patients with long-term intravascular catheters. A culture from one atomizer that contained diluted 2.5% chlorhexidine, which had been used to disinfect the skin, yielded A. xylosoxidans subsp. xylosoxidans. No further cases were diagnosed once the use of this atomizer was discontinued. Five outbreak-related strains from the four patients and the atomizer were tested by pulsed-field gel electrophoresis (PFGE) under XbaI restriction. The isolates from the first three patients and the atomizer had identical PFGE patterns, confirming the atomizer as the source of the outbreak. The strain isolated from the fourth patient had six more bands than the outbreak strain and was considered possibly related to the outbreak strain. All patients were treated with intravenous levofloxacin. The catheter was removed in only one patient. The three patients in whom the catheter was left in place were also treated with antibiotic lock therapy with levofloxacin. All four patients were cured. This is believed to be the first reported outbreak of central venous catheter-related bacteremia due to A. xylosoxidans and the second reported outbreak with this organism associated with chlorhexidine atomizers. The use of diluted chlorhexidine via atomizers can be dangerous for the care of venous catheters and should be called into question. Patients with long-term intravascular catheter-related bacteremia due to this organism can be treated successfully with systemic antimicrobial therapy in addition to antibiotic lock therapy without catheter removal.

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

    The benefit of the transurethral catheter to protect or measure renal function is well accepted. Urethral stricture and infection of the lower urinary tract as the complications should lead to a cautious use of catheters. A careful placement, the choice of the best material and a correct management help to avoid complications. Alternatives are discussed.

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

    Full Text Available 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.

    Intra-atrial re-entrant tachycardias (IARTs) are common late after heart surgery. Conventional mapping and ablation is relatively difficult because of the complicated anatomy and multiple potential re-entry loops. In this study we aimed to evaluate the electrophysiological characteristics and radiofrequency catheter ablation of atrial tachycardia (AT) induced by myocardial scar or incision. Methods In 6 patients (three male and three female, aged 33.3+ 11.8 years) who had AT related to myocardial scar or incision,electrophysiological study and radiofrequency catheter ablation (RFCA) were performed. Earliest activation combined with entrainment mapping was adopted to determine a critical isthmus. Results Re-entry related to the lateral atriotomy scar was inducible in 5 of6 patients. With entrainment mapping, the PPI (post-pacing interval)-TCL (tachycardia cycle length) difference was <30 ms when pacing at the inferior margins of the right lateral atriotomy scar. Among them, 3 patients had successful linear ablation between scar area to inferior vena cava, and 2 patients between scar area to tricuspid annulus. Re-entry involving an ASD patch was demonstrated in 1 of 6 patients. PPI-TCL differences <30 ms were observed when entraining tachycardia at sites near the septal patch. But linear ablation failed in terminating AT. There was no complication during procedure. No recurrence of AT related to incision was observed during follow-up except for the failed patient. Conclusion Under conventional electrophysiological mapping, adopting linear ablation from scar area to anatomic barrier, successful ablation can be obtained in patients with IRATs related to myocardial scar or incision.

    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.

    Background The Agency for Healthcare Research and Quality (AHRQ) has funded national collaboratives using the Comprehensive Unit-based Safety Program to reduce rates of two catheter-associated infections—central-line-associated bloodstream infection (CLABSI) and catheter-associated urinary tract infection (CAUTI), using evidence-based intervention bundles to improve technical aspects of care and socioadaptive approaches to foster a culture of safety. Objective Examine the association between hospital units' results for the Hospital Survey on Patient Safety Culture (HSOPS) and catheter-associated infection rates. Methods We analysed data from two prospective cohort studies from acute-care intensive care units (ICUs) and non-ICUs participating in the AHRQ CLABSI and CAUTI collaboratives. National Healthcare Safety Network catheter-associated infections per 1000 catheter-days were collected at baseline and quarterly postimplementation. The HSOPS was collected at baseline and again 1 year later. Infection rates were modelled using multilevel negative binomial models as a function of HSOPS components over time, adjusted for hospital-level characteristics. Results 1821 units from 1079 hospitals (CLABSI) and 1576 units from 949 hospitals (CAUTI) were included. Among responding units, infection rates declined over the project periods (by 47% for CLABSI, by 23% for CAUTI, unadjusted). No significant associations were found between CLABSI or CAUTI rates and HSOPS measures at baseline or over time. Conclusions We found no association between results of the HSOPS and catheter-associated infection rates when measured at baseline and postintervention in two successful large national collaboratives focused on prevention of CLABSI and CAUTI. These results suggest that it may be possible to improve CLABSI and CAUTI rates without making significant changes in safety culture, particularly as measured by instruments like HSOPS.

    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 (Pvenous thrombosis history (Prisk 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.

    Full Text Available Background: Indwelling medical devices (IMDs in critical patients are vulnerable to colonization by biofilm producing bacteria. Complex characteristics of bacterial biofilms promote antibiotic resistance, leading to the emergence of resistant device-related infections (DRI, which pose new challenges in their management. Materials and Methods : The study was done on 135 hospitalized (Intensive care units pediatric patients with IMDs (intravascular catheter, urinary catheter, and endotracheal tube to determine the device-specific infection rates. Biofilm formations were demonstrated by the tube method and by scanning electron microscopy (SEM. Bacteria in biofilms were identified by the standard conventional methods and tested for antibiotic resistance. We also detected the presence of extended spectrum β-lactamases (ESβLs, particularly, blaCTX-M, in gram-negative isolates. Results: The rates of biofilm-based catheter-related blood stream infections (CRBSI, catheter-associated urinary tract infections (CAUTI, and Ventilator Associated Pneumonia (VAP, in our study, were 10.4, 26.6, and 20%. Biofilm formation by the tube method correlated well with the SEM findings. A majority of infections were caused by Klebsiella pneumoniae followed by Staphylococcal biofilms. A high percentage (85.7%, 95% confidence interval 64.5 to 95.8% of biofilm producing bacterial isolates, causing infection, were multidrug resistant. Many biofilm producing gram-negative isolates were ESβLs producers, and a majority particularly harbored blaCTX-M, among the ESβLs genotypes. Conclusion: The incidence of resistant device-related infections, predominantly caused by biofilm producing bacteria, is rising. The tube method is an effective screening method to test biofilm production, where sophisticated microscopy facilities are not available. The varying resistance pattern of organisms isolated in our setup, emphasizes the importance of studying the pattern of infection in

    Full Text Available Introduction: Urinary tract infections range among the most frequent infections not only in hospital patients but also in residents of long-term care facilities for the elderly. Urinary catheters are the greatest risk factor for urinary tract infections. In the guidance paper on the “prevention of infections in nursing homes” (2005 as well as in the updated recommendations for the “prevention and control of catheter-associated urinary tract infections” (2015, the Commission for Hospital Hygiene and Infection Prevention (KRINKO has recommended adequate preventive measures. In 2015, the implementation of these KRINKO recommendations was investigated.Method: All of Frankfurt’s 40 nursing homes were evaluated using a checklist based on the KRINKO recommendations. The evaluation included assessing the availability of operating instructions, appropriate indications for the placement of catheters etc. Age, sex and duration of catheterization, as well as current and previous infections within the past 6 months were documented for every resident with a catheter.Results: In 35 (87.5% of the nursing homes, operating instructions for the handling of urinary tract catheters were available. The decision as to whether a catheter is indicated is made by physicians, while its placement is often delegated to the nursing service. Typically, silicon catheters are used. In three-quarters of the nursing homes, regular intervals of 4–6 weeks for changing catheters were reported. On the respective survey day, 7.3% of the residents were catheterized. On the survey day, 3.6% (4.2% and in the previous 6 months a total of 28% (28.9% of the residents had a urinary tract infection (prevalence of antibiotic therapy in parentheses. Ciprofloxacin was used most often followed by cefuroxime and cotrimoxazole.Discussion: In the current evaluation, fewer nursing home residents were catheterized than in previous years and the rate of urinary tract infections was low

    There are limited data on the incidence of subsequent bloodstream infection (BSI) and the effect of systemic antibiotics in patients who had positive catheter-drawn blood cultures (CBC) and negative peripheral blood cultures (PBC). We retrospectively reviewed all paired blood cultures from patients with Hickman catheter in the hematology-oncology ward between January 1997 and December 2008. There were 112 episodes with positive CBC and negative PBC. Nine episodes (8.0%; 95% CI, 3.0-13.1%) led to subsequent BSI within 28 days. Subsequent BSI developed in 6 of 31 episodes (19%) where empiric antibiotics were inappropriate but in 3 of 81 episodes (4%) where empiric antibiotics were appropriate (P = 0.01). Subsequent candidemia (50%, 2 of 4) was more common than subsequent bacteremia (6%, 7 of 108) (P = 0.03). In conclusion, for patients with positive CBC and negative PBC, the overall incidence of subsequent BSI was 8.0%, and inappropriate empiric antibiotics was associated with subsequent BSI.

    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 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.

    Full Text Available Aim: The Commission for Hospital Hygiene and Infection Prevention (KRINKO updated the recommendations for the prevention of catheter-associated urinary tract infections in 2015. This article will describe the implementation of these recommendations in Frankfurt’s hospitals in autumn, 2015.Material and methods: In two non-ICU wards of each of Frankfurt’s , inspections were performed using a checklist based on the new KRINKO recommendations. In one large hospital, a total of were inspected. The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model.Results: Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%. In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change.Conclusion: Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two

    Applications of surface and physico-chemical techniques to the clinical setting, in particular related to the urogenital tract, have been sporadic, often concentrating on aspects of biocompatibility and interactions of blood cells with materials. In an era where billions of such devices are implanted annually, it is important to utilize such techniques to improve our understanding of material-host interactions. In an effort to encourage further such interactive investigations, this review will illustrate some practical biomedical examples where utilization of sophisticated surface-science techniques has provided valuable insight into interfacial events between host components, micro-organisms and material surfaces. Techniques to reduce bacterial infection and encrustations will be discussed, and suggestions given for future lines of enquiry.

    Staphylococcus spp. is a major cause of device-related infections. However, the mechanisms of deep-tissue infection by staphylococci from the skin surface remain unclear. We performed in vitro experiments to determine how staphylococci are transferred from the surface to the deeper layers of agar along the catheter for different strains of Staphylococcus aureus with respect to bacterial concentrations, catheter movements, and biofilm formation. We found that when 5-mm reciprocal movements of the catheter were repeated every 8h, all catheter samples of S. aureus penetrated the typical distance of 50mm from the skin to the epidural space. The number of reciprocal catheter movements and the depth of bacterial growth were correlated. A greater regression coefficient for different strains implied faster bacterial growth. Enhanced biofilm formation by different strains implied larger regression coefficients. Increased biofilm formation ability may accelerate S. aureus transport along a catheter due to physical movements by patients.

    We report the case of a 63-year-old man who has a 19-year history of involvement in the implantable insulin pump program at Johns Hopkins University. After his most recent pump implantation in February 2004, his 24-h insulin requirement gradually increased from a baseline of 75 units to a peak of almost 500 units in June 2005. Surprisingly, insulin delivery from the pump and glycemic control remained satisfactory despite the dramatic change in insulin requirement. Laparotomy revealed a fibrous mass in the peritoneal cavity, with the track of the catheter extending into the mass. Insulin requirement declined post-resection of the mass and relocation of the catheter tip.

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

    Catheter-related bacteremia (CRB) is a typical complication of hemodialysis catheter use. Catheter lumen colonization by pathogens is regarded as a direct cause of CRB. Once settled, the catheter biofilm increases the risk of developing infection, thus necessitating insertion replacement and antibiotic treatment. The study assessed the self-sufficient efficacy of taurolidine-citrate-heparin lock solution in eradicating catheter biofilm bacteria and keeping it sterile in patients on hemodialysis. Twenty-nine chronic patients on hemodialysis with tunneled and nontunneled catheters locked with a heparin filling (the mean time of heparin lock use -30.1 ± 2.0 days) and subsequently converted to a taurolidine-citrate-heparin filling were included. Peripheral vein and catheter lumen blood cultures were obtained before the filling change and after taurolidine-citrate-heparin lock use (mean time 33.8 ± 7.6 days). Twenty-four participants with tunneled and nontunneled catheters locked with taurolidine-citrate-heparin filling served as the control group. During the heparin-locking period, CRB was diagnosed in 3 cases (only nontunneled catheters). The catheter blood cultures findings were positive in 23 patients (10 temporary and 13 permanent catheters), whereas both the catheter and peripheral vein blood cultures were sterile in 3 of 29 subjects (only permanent catheters). Irrespective of catheter type (tunneled or nontunneled), repeated culture revealed no pathogens in any of the 23 patients with initial positive catheter blood culture, after the use of taurolidine-citrate-heparin filling. No positive blood culture was noted in the control group. The taurolidine-citrate-heparin lock solution effectively eradicated pathogens from nontunneled and tunneled catheter biofilms and helped to maintain catheter lumen sterility.

    Full Text Available Background Developments in the use of central venous catheters have improved the treatment of critically ill newborns. Objectives The aim of this retrospective study was to evaluate the rate of catheter-related complications and associated risk factors in newborns. Patients and Methods This cross sectional study evaluated 60 infants with indications for central venous catheters who were selected by census from 2007 to 2014 in Baqiyatallah Hospital in Tehran, Iran. The catheters were Broviac numbers 14 - 16. Results Ultimately, 60 cases (17 males and 43 females with a mean age of 26.25 ± 20.09 days (Min = 1 day and Max = 153 days underwent analysis. The most common reasons for venous catheter placement (98.3% were prolonged hospitalization and lack of peripheral vessels. The most common complication was catheter-related infection, which occurred in 20 patients (33.3%. Death occurred in 24 patients (40.0%, but only 3 deaths (5% were due to complications from the central venous catheter. A significant relationship was evident between infection and catheterization duration (P = 0.02. Conclusions Most of the catheter-related deaths were due to severe sepsis and hemothorax, and a significant relationship was noted between infection and both the mortality rate and catheterization duration. A significant relationship was also evident between birth weight and infection rates.

    Full Text Available Background. Catheter-related infections, thrombosis, and stenosis are among the most frequent complications associated with catheters, which are inserted in vessels. Surface treatment processes of the outer surface, such as ion-beam-assisted deposition, can be used to mitigate such complications. Methods. This retrospective study (1992–2007 evaluated silver-coated (54 patients and noncoated (105 patients implanted large-bore catheters used for extracorporeal detoxification. The catheters were inserted into the internal jugular or subclavian veins. After removal, the catheters were cultured for bacterial colonization using standard microbiologic assays. They also were examined using scanning electron microscope. Results. The silver coated catheters showed a tendency towards longer in situ time. The microbiologic examinations of the catheter tips were in both catheter types high positive, but not significant. Conclusion. The silver-coated catheters showed no significantly reduction in infection rate by evaluation of all collected data in this retrospective study. There was no association between both catheters in significantly reducing savings in treatment costs and in reducing patient discomfort. Other new developed catheter materials such as the microdomain-structured inner and outer surface are considered more biocompatible because they mimic the structure of natural biological surface.

    Full Text Available Abstract Background This study assesses the impact that a resident oversight and credentialing policy for central venous catheter (CVC placement had on institution-wide central line associated bloodstream infections (CLABSI. We therefore investigated the rate of CLABSI per 1,000 line days during the 12 months before and after implementation of the policy. Methods This is a retrospective analysis of prospectively collected data at an academic medical center with four adult ICUs and a pediatric ICU. All patients undergoing non-tunneled CVC placement were included in the study. Data was collected on CLABSI, line days, and serious adverse events in the year prior to and following policy implementation on 9/01/08. Results A total of 813 supervised central lines were self-reported by residents in four departments. Statistical analysis was performed using paired Wilcoxon signed rank tests. There were reductions in median CLABSI rate (3.52 vs. 2.26; p = 0.015, number of CLBSI per month (16.0 to 10.0; p = 0.012, and line days (4495 vs. 4193; p = 0.019. No serious adverse events reported to the Pennsylvania Patient Safety Authority. Conclusions Implementation of a new CVC resident oversight and credentialing policy has been significantly associated with an institution-wide reduction in the rate of CLABSI per 1,000 central line days and total central line days. No serious adverse events were reported. Similar resident oversight policies may benefit other teaching institutions, and support concurrent organizational efforts to reduce hospital acquired infections.

    2009-01-01

    Full Text Available Tunneled dialysis catheters (TDCs are associated with the highest rate of complications, morbidity, and mortality when compared to arteriovenous fistulas or grafts, and this relates to higher costs in their management. Over time, catheters are prone to higher rates of infection, thrombosis, and central venous stenosis, and, thereby, catheter dysfunction. Lower blood flow rates are a consequence of the dysfuncion. Despite efforts to reduce incident and prevalent rates of catheter use for dialysis by the National Kidney Foundation and Fistula First Initiative, they remain a common modality of hemodialysis. The management of common TDC-related complications is discussed, in addition to ways to reduce and prevent morbidity associated with their use.

    Herein we present a supramolecular (delayed luminescent) Eu(III)-based pH-responsive probe/sensor with the ability to detect the urease-mediated hydrolysis of urea in aqueous solution. A series of photophysical titrations show this Eu(III) chelate behaves as an "on-off" luminescent switching probe, with its luminescence being quenched upon urea being enzymatically converted into ammonia and carbon dioxide. Calculation of the rate constant (k) and activation energy (Ea) for this hydrolysis reaction are detailed; the results demonstrate a direct observation of enzymatic activity in solution by the sensor. The potential application of this probe in detecting the onset of catheter-associated urinary tract infections (CAUTIs) is also demonstrated by incorporating 1.Eu into water-permeable hydrogels that can be utilized as an alternative coating for catheters.

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

    BACKGROUND Catheter-associated urinary tract infections (CAUTIs) are among the most common hospital-acquired infections (HAIs). Reducing CAUTI rates has become a major focus of attention due to increasing public health concerns and reimbursement implications. OBJECTIVE To implement and describe a multifaceted intervention to decrease CAUTIs in our ICUs with an emphasis on indications for obtaining a urine culture. METHODS A project team composed of all critical care disciplines was assembled to address an institutional goal of decreasing CAUTIs. Interventions implemented between year 1 and year 2 included protocols recommended by the Centers for Disease Control and Prevention for placement, maintenance, and removal of catheters. Leaders from all critical care disciplines agreed to align routine culturing practice with American College of Critical Care Medicine (ACCCM) and Infectious Disease Society of America (IDSA) guidelines for evaluating a fever in a critically ill patient. Surveillance data for CAUTI and hospital-acquired bloodstream infection (HABSI) were recorded prospectively according to National Healthcare Safety Network (NHSN) protocols. Device utilization ratios (DURs), rates of CAUTI, HABSI, and urine cultures were calculated and compared. RESULTS The CAUTI rate decreased from 3.0 per 1,000 catheter days in 2013 to 1.9 in 2014. The DUR was 0.7 in 2013 and 0.68 in 2014. The HABSI rates per 1,000 patient days decreased from 2.8 in 2013 to 2.4 in 2014. CONCLUSIONS Effectively reducing ICU CAUTI rates requires a multifaceted and collaborative approach; stewardship of culturing was a key and safe component of our successful reduction efforts.

    A commercially available polyvinyl chloride intravenous catheter was studied in 9 horses for 3 to 10 days to evaluate the catheter's suitability for use in the horse, to develop a new insertion technique, and to establish a protocol for catheter care. Seven of the animals were clinically normal horses receiving parenteral nutrition; one was a horse with hypocalcemia receiving frequent intravenous injections of calcium gluconate, and one was a clinically normal horse receiving no infusions. The catheter dressings were changed every 48 hours, and an aspirate from the catheter and the catheter tip was cultured at the time of catheter removal. One catheter became infected following a break in the protocol. It was concluded that the polyvinyl catheter is suitable for use in the horse and that the proposed protocol for catheter insertion and maintenance may reduce the likelihood of complications such as catheter sepsis, thrombophlebitis, and embolism.

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

    Full Text Available INTRODUCTION: Catheter-associated bloodstream infection (CA-BSI is the most common nosocomial infection in neonatal intensive care units. There is evidence that care bundles to reduce CA-BSI are effective in the adult literature. The aim of this study was to reduce CA-BSI in a Brazilian neonatal intensive care unit by means of a care bundle including few strategies or procedures of prevention and control of these infections. METHODS: An intervention designed to reduce CA-BSI with five evidence-based procedures was conducted. RESULTS: A total of sixty-seven (26.7% CA-BSIs were observed. There were 46 (32% episodes of culture-proven sepsis in group preintervention (24.1 per 1,000 catheter days [CVC days]. Neonates in the group after implementation of the intervention had 21 (19.6% episodes of CA-BSI (14.9 per 1,000 CVC days. The incidence of CA-BSI decreased significantly after the intervention from the group preintervention and postintervention (32% to 19.6%, 24.1 per 1,000 CVC days to 14.9 per 1,000 CVC days, p=0.04. In the multiple logistic regression analysis, the use of more than 3 antibiotics and length of stay >8 days were independent risk factors for BSI. CONCLUSIONS: A stepwise introduction of evidence-based intervention and intensive and continuous education of all healthcare workers are effective in reducing CA-BSI.

    Full Text Available Introduction: Central venous catheter (CVC plays an essential part in clinical management of patients admitted in Intensive Care Unit (ICU, even though catheterization is an invasive procedure that may facilitate bacterial migration from the skin surrounding the catheter insertion site to the catheter tip, representing a risk factor for the arise of bacteraemia and sepsis. Aim of our study was to assess the prevalence of micro-organisms found as responsibles of CVC-related infections and check their correspondence with those found in blood cultures collected from the same patients. Methods: The study was conduced from April 2008 to March 2009. In this period were analysed 29 CVC samples sent from ICU to the laboratory of the Salam Center for Cardiac Surgery of Khartoum (Sudan. CVC was removed after pericatheter skin disinfection and its tip was cut, put in a sterile container and finally sent to the laboratory, where it was immersed in Brain Heart Infusion (BHI and incubated at 37°C.A first culture of the sample on Blood Agar plate was done after an incubation period of 1 hour, the second one after 24 hours. In case of bacterial growth were practiced identification and sensitivity test of the isolated bacteria. Results: Of the 29 analysed samples 38% showed bacterial growth of which 27% caused by gram positive and 73% by gram negative bacteria. The identification tests showed also that among gram positive-related infection predominated those caused by Methicillin-Resistent Staphylococcus aureus (MRSA (67%, while among the gram negative infections predominated those caused by Pseudomonas spp (57%, followed by Enterobacter spp and Serratia spp. Conclusion: All the above mentioned infections were confirmed by examination of blood cultures collected simultaneously from the same patients. Furthermore the study showed that 73% of infections affected post-operative patients rather than those waiting for surgery.

    Central line-associated bloodstream infections (CLABSIs) are not easily treated, and many catheters (e.g., hemodialysis catheters) are not easily replaced. Biofilms (the source of infection) on catheter surfaces are notoriously difficult to eradicate. We have recently demonstrated that modest elevations of temperature lead to increased staphylococcal susceptibility to vancomycin and significantly soften the biofilm matrix. In this study, using a combination of microbiological, computational, and experimental studies, we demonstrate the efficacy, feasibility, and safety of using heat as an adjuvant treatment for infected hemodialysis catheters. Specifically, we show that treating with heat in the presence of antibiotics led to additive killing of Staphylococcus epidermidis with similar trends seen for Staphylococcus aureus and Klebsiella pneumoniae. The magnitude of temperature elevation required is relatively modest (45-50°C) and similar to that used as an adjuvant to traditional cancer therapy. Using a custom-designed benchtop model of a hemodialysis catheter, positioned with tip in the human vena cava as well as computational fluid dynamic simulations, we demonstrate that these temperature elevations are likely achievable in situ with minimal increased in overall blood temperature.

    2016-07-01

    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.

    Full Text Available Nosocomial infection is one of the most common causes of adverse events and complications related to health care. Development of nosocomial infection is associated with an increase in hospital stay and mortality and an overall increase in health care costs. Knowing the incidence of nosocomial infection is an effective way of controlling and preventing it. Identifying the relationship between nursing workload and nosocomial infections in critical care may be helpful to adjust the staff to the real requirements of the intensive care unit and may help reducing costs. The aim of the present study is to analyze the influence of nursing workload in the development of nosocomial infections in patients admitted to an intensive care unit. A longitudinal correlational research will be performed. The sample will be comprised of the patients admitted in the intensive care unit of the Hospital Universitario Fundación Alcorcón.Data regarding sociodemographical variables, ventilador-associated pneumonia, intravascular catheter location and duration, urinary catheter type and duration, and all pertinent cultures will be obtained from the medical records. Nursing Activities Score scale will be used to assess daily nursing workload in the unit. The number of patients admitted daily, as well as the number of nursing professionals working in each shift will also be taken into account.

    Conclusions: Most urinary catheters marketed in developing countries are unidentifiable after unpacking. A catheterization diary is a useful tool for solving catheter-related problems, and its application in health-care facilities should be encouraged. Companies marketing Foley catheters should print the catheter name on both the catheter packaging and on the catheter itself.

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

    To evaluate the results and complications of the step tip type and split tip type tunneled hemodialysis catheters. Between March 2008 and December 2008, a total of 147 tunneled hemodialysis catheters of step tip (n=89) and split tip (n=58) type were placed in 126 patients to perform hemodialysis. We evaluated the number of catheterization days, as well as complications with respect to catheter tip types. A tunneled hemodialysis catheter was placed successfully in all cases. The duration of catheterization ranged from 7 to 180 days (mean 68, total catheter days: 10,504 days). A significantly higher complication rate was observed in the step tip type (n=23) as compared to the split tip type (n=4) (p=0.004), especially due to catheter dysfunction and catheter laceration. Five cases of catheter-related infection (3.4%, 0.48/1000 catheter days) were observed. Placement of the tunneled hemodialysis catheter of step tip type and spit tip type were performed safely. However, the split tip type is more useful because of the greater rate of complication in step tip type

    Taurolidine has demonstrated inhibition of biofilm formation in vitro. The aim of this study was to compare the effect of catheter locking with taurolidine vs heparin in biofilm formation in central venous catheters. Forty-eight children with cancer were randomized to catheter locking by heparin (n = 22) or taurolidine (n = 26), respectively. After removal, catheters were examined by standardized scanning electron microscopy to assess quantitative biofilm formation. Biofilm was present if morphologically typical structures and bacterial cells were identified. Quantitative and semi-quantitative cultures were also performed. Biofilm was identified in 23 of 26 catheters from the taurolidine group and 21 of 22 catheters from the heparin group. A positive culture was made of six of the catheters locked with taurolidine and heparin, respectively (p = 0.78). The rate of catheter-related bloodstream infections (CRBSI) was 0.1 per 1000 catheter-days using taurolidine and 0.9 per 1000 catheter-days using heparin (p = 0.03). This randomized trial confirmed that the use of taurolidine as catheter-lock compared with heparin reduced the rate of CRBSIs; this reduction was not related to a reduction in the intraluminal biofilm formation and the rate of bacterial colonization detected by scanning electron microscopy in the two groups.

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

    Directory of Open Access Journals (Sweden)

    Gernot Schilcher

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

    OBJECTIVE In this single-center study the authors investigated the complications occurring before and after the introduction of the new Ascenda intrathecal catheter (Medtronic Inc.) in pediatric patients treated with intrathecal baclofen therapy (ITB) for spasticity and/or dystonia. METHODS This was a retrospective review of 508 children who had received ITB, 416 with silicone catheters in the 13 years between September 1998 and September 2011 and 92 with Ascenda catheters in the 3 years between September 2011 and August 2014. The authors evaluated major complications such as infections, CSF leaks treated, and problems related to the catheter or pump, and they compared the 2 groups of patients who had received either a silicone catheter or an Ascenda catheter implant. RESULTS One hundred twenty patients in the silicone group (29%) and 1 patient in the Ascenda group (1.1%; p < 0.001) had a major complication. In the silicone group 23 patients (5.5%) were affected by CSF leakage and 75 patients (18%) experienced 82 catheter-related events, such as occlusion, dislodgment, disconnection, or breakage, which required catheter replacement. In the Ascenda group, only 1 patient (1.1%) was affected by CSF leakage. CONCLUSIONS To the authors' knowledge, this study is the first in the literature to compare the performance of the new Ascenda catheter, introduced in 2011, with the traditional silicone catheter for intrathecal drug infusion. In their analysis, the authors found that the Ascenda catheter can reduce major complications related to the catheter after ITB pump implantation. Further investigation is necessary to expand on and confirm their results.

    We reviewed all episodes of peritonitis associated with exit site and/or tunnel infection (n = 87; rate, 0.1/yr; 13% of all peritonitis episodes) occurring from 1979 to 1995. The exit site or tunnel infection was diagnosed at the time or shortly after the patient presented with peritonitis in 66% of the episodes. In the other one third the exit site or tunnel infection was diagnosed a median of 40 days prior to the development of peritonitis. Staphylococcus aureus accounted for 52% of episodes. Pseudomonas aeruginosa was the next most common organism. In 63 (72%) of the episodes the catheter was removed to resolve the infection at a median of 8 days (range, 0 to 226 days) from the onset of peritonitis. Catheter removal after 5 days predominately for refractory peritonitis (n = 23; median time to removal, 8 days) or relapsing peritonitis (n = 11; median time to catheter removal, 103 days). Patients with relapsing peritonitis suffered two to four episodes prior to removal of the catheter. Patients with peritonitis associated with tunnel infection were more likely to lose their catheter than patients with peritonitis associated with exit site infection (86% v 58%), while Staphylococcus epidermidis infections were less likely to result in catheter loss compared with all other organisms (15% v 82%). After a protocol to reduce S aureus catheter infections was implemented in 1990, the rate of catheter-related peritonitis decreased from 0.14/yr to 0.05/yr due to a decrease in S aureus episodes. We conclude that peritonitis episodes associated with a tunnel infection infrequently resolve without catheter removal. Delayed catheter removal in such circumstances often results in refractory or relapsing peritonitis. Therefore, catheter removal should be done promptly. Antibiotic prophylaxis for S aureus can reduce catheter-related peritonitis.

    Urethral catheterization is a predictor of agitation during the general anesthesia recovery period. The aim of this study was to determine the effect of intraurethral 5% lidocaine and 25 mg/g prilocaine cream in reducing catheter-related bladder discomfort (CRBD) in male patients during the general anesthesia recovery period. Adult male patients undergoing elective operations that required urinary catheterization under general anesthesia were enrolled and assigned randomly to 2 groups. In the lidocaine-prilocaine cream group (n = 72), approximately 5 g of topical cream was spread in the preputial sac, the glans, the meatus, and on the urinary catheter surface before urinary catheterization. In the control group (n = 74), the urinary catheter was lubricated with lidocaine gel. The incidence and severity of CRBD were assessed 15, 30, 45, and 60 minutes postoperatively. We found that the incidence of CRBD in the lidocaine-prilocaine cream group was significantly lower than in the control group. Multivariate logistic regression analysis showed that lidocaine-prilocaine cream applications reduced moderate or severe CRBD. Thirty minutes postoperation was the most frequent time point for the incidence of CRBD. Application of lidocaine-prilocaine cream on the surface of the urinary catheter is an efficient and safe method to reduce the incidence and severity of CRBD.

    Objective The aim of this study was to compare the results of urine cultures obtained either from urethral, and percutaneous nephrostomy (PCN) catheters. Materials and methods This study included 328 consecutive patients that underwent PCN at our institution with complicated urinary tract infections (UTIs) between July 2010 and April 2015. Results of urine cultures obtained from the urethral and nephrostomy catheters were compared. Results This study included 152 male and 176 female patients. Mean age of the patients was 46.2±24.3 years. The main indications were obstructive uropathy due to urolithiasis complicated with pyonephrosis 145 (44%), malignant disease (n=87; 26%), pregnancy (n=26; 8%), and anatomical abnormality (n=23; 7%). One hundred and twenty three patients had diabetes mellitus. The most common causative organisms were Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Blood cultures showed the same results for the PCN and bladder urine cultures. The bladder urine culture was positive in 304 patients, while the PCN urine culture in 314 patients. Conclusion PCN is an important treatment for the management of pyonephrosis. Cultures from the PCN yield valuable information that is not available from urethral urine cultures, and is a guiding tool for antibiotic therapy selection. PMID:27909624

    To evaluate the technical success and complication rates of tunneled-cuffed catheter insertions radiologically placed via the internal jugular vein in patients with different types of underlying diseases. A total of 2153 tunneled-cuffed catheter insertions performed in 1926 patients between January 2008 and December 2012 were retrospectively reviewed. All procedures were conducted using sonography and fluoroscopy. The number of catheter maintenance days, technical success rates, and complication rates were analyzed based on radiologic and medical records. A total of 204809 catheter maintenance days (mean, 95.35 days; range, 0-1710 days) were recorded. Technical success was achieved in 2148 insertions (99.77%). A total of 185 complications (8.61%, 0.903/1000 catheter days) were observed, including 22 procedure-related complications (1.02%). A total of 143 catheters (6.66%) were removed due to complications. Significant differences in complication rates were observed between patients with or without underlying hematologic diseases (11.65% vs. 7.02%, respectively; p = 0.000). Significant differences in catheter thrombosis were observed between patients in which right-sided or left-sided venous approaches were used (0.81% vs. 2.70%, respectively; p = 0.010). The very high technical success rates and very low procedure-related complication rates indicate insertion of a tunneled-cuffed catheter radiologically placed via the internal jugular vein is safe and effective.

    The need to obtain dependable access to the vascular system constitutes a significant component in the treatment and management of critically ill patients. Intravenous chemotherapy administered to cancer patients over an extended period of time often results in loss of peripheral vascular access due to vein sclerosis, "exhaustion" or tissue necrosis. Medical investigators have designed and steadily upgraded a variety of devices constructed to improve venous access for long-term utilization. As with the introduction of any foreign object into the body, each of these devices has complications which may be life threatening and occasionally fatal. We present an unusual case of iatrogenic acute hydropericardium and cardiac tamponade caused by the percutaneous infusion of chemotherapeutic fluid via a right subclavian central venous implant system (Port-a-Cath). Failure to implant and monitor the device with a radiograph following placement according to manufacturer's guidelines and accepted standards of medical practice were causally related to an unusual complication, namely, perforation of the right cardiac ventricle by the catheter tip, resulting in sudden and unexpected cardiac death.

    The aim of this study was to report catheter malposition during voiding cystourethrography. Eight hundred forty-three voiding cystourethrography (265 males and 578 females, aged 1 week to 12 years, mean age 2 years) were performed during a period of 4 years. The conventional standard procedure was applied. In 3 cases with passed history of urinary tract infection the catheter entered directly into the ureter. In all these cases the uretero-vesical reflux was present on the same side where the catheter entered. It appears that insertion of a catheter into the ureter is possible only in the presence of an anomaly or pathology at the vesicoureteric junction. (orig.)

    Although, decreasing in incidence with the disconnection systems, the first complication is still peritonitis in patients with chronic renal failure and the second is infection of Tenckhoff catheter exit-site. All efforts made to diminish the frequency of exit-site infection lower the possibility of peritonitis. The pediatric population is well-known to have a major risk of infectious complications, and making easy and safe the care of the exit-site will prevent the peritonitis that follows. The aim of the study was to evaluate the efficacy of the Amuchina 10% solution vs. pH neutral soap in children with chronic renal failure, on preventing exit-site infection. There were 60 patients who were assigned randomly to one of two groups. One group used Amuchina 10% solution for the daily cleaning of the exit-site, and the other used pH neutral soap, with 14 months of follow-up. Before the study they have to be free of infection for at least 30 days. All were taught by the same nurse how to clean their exit-site. Groups were almost identical in years, sex, and time on dialysis. We had nine infections in the soap group and none in the Amuchina 10% solution group, with an OR: 17 (p = 0.004). From these nine infections, the bacteria isolated were: 4 (13%) were caused by Pseudomona aeruginosa, 1 (3.3%) by Staphylococcus aureus, coagulase-positive staphylococci in 2 (6.6%) and Serratia marcensens in 1 (3.3%). In conclusion, Amuchina 10% solution is effective in preventing infection on the exit-site, without any secondary topical reaction.

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

    Transtracheal aspiration, percutaneous lung biopsy, and tracheal aspiration can be dangerous and/or unreliable methods for obtaining specimens of pulmonary secretions for culture. Using a blind technique, we evaluated the efficacy of a double-lumen catheter (DLC) with a polyethylene glycol plug in obtaining specimens of respiratory tract secretions for culture, and compared these results with simultaneously obtained cultures of tracheal aspirates. Twenty-seven intubated children already receiving antibiotic therapy were studied. Sixteen (59%) DLC specimens were sterile, as opposed to only 6 (22%) tracheal aspirates. Only 2 (8%) of the DLC specimens were contaminated. Two DLC specimens yielded significant bacterial growth (at least 10(5) colony-forming units/ml). Using DLC culture data, there was an 81% success rate in making decisions concerning antibiotic selection. We conclude that blind use of the DLC is a safe and reliable method of obtaining pulmonary secretion specimens for culture.

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

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

    Catheter ablation is an important option to treat ventricular tachycardias (VT). Scar-related VT is among the most difficult to treat, because myocardial scar, which is the underlying arrhythmogenic substrate, is patient-specific and often highly complex. The scar image from preprocedural late gadolinium enhancement magnetic resonance imaging (LGE- MRI) can provide high-resolution substrate information and, if integrated at the early stage of the procedure, can largely facilitate the procedure with image guidance. In clinical practice, however, early MRI integration is difficult because available integration tools rely on matching the MRI surface mesh and electroanatomical mapping (EAM) points, which is only possible after extensive EAM has been performed. In this paper, we propose to use a priori information on patient posture and a multi-sequence MRI integration framework to achieve accurate MRI integration that can be accomplished at an early stage of the procedure. From the MRI sequences, the left ventricular (LV) geometry, myocardial scar characteristics, and an anatomical landmark indicating the origin of the left main coronary artery are obtained preprocedurally using image processing techniques. Thereby the integration can be realized at the beginning of the procedure after acquiring a single mapping point. The integration method has been evaluated postprocedurally in terms of LV shape match and actual scar match. Compared to the iterative closest point (ICP) method that uses high-intensity mapping (225+/-49 points), our method using one mapping point reached a mean point-to-surface distance of 5.09+/-1.09 mm (vs. 3.85+/-0.60 mm, p<0.05), and scar correlation of -0.51+/-0.14 (vs. -0.50+/-0.14, p=NS).

    We sought to evaluate the effectiveness of the American Urological Association (AUA) antibiotic prophylaxis guidelines in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP). Our prospective registry database was reviewed for all RALP cases. The following variables were evaluated: age, associated comorbidities, body mass index (BMI), total operative time, length of stay (LOS), prostate weight, pathological grade and stage. Until 11/2011, RALP patients were treated with antibiotics administered in the operating room and continued until urethral catheter removal. Since 11/2011, all patients were treated with a single intravenous dose of Cephalosporin and Aminoglycoside given within 30 min of surgical incision. The rate of catheter-associated urinary tract infection (CAUTI) was evaluated in both groups. 229 RALP patients were identified. The first 60 patients (26.2%) were treated according to the old protocol (Group 1) while the remaining 169 (73.8%) were treated according to the new protocol (Group 2). Group match was identified in all categories but LOS. Moreover, LOS was found to be longer in Group 1 compared with Group 2 (5.8 vs. 4.5 days, p < 0.001). CAUTI rate was similar in both groups (8.3 vs. 8.9%, respectively, p = 0.89). Logistic regression analysis did not demonstrate any association between treatment protocol and potential risk for CAUTI. Therefore, a single preoperative dose of antibiotics does not increase the rate of CAUTI following RALP compared with prolonged antibiotic treatment. Moreover, it was found to be associated with shorter LOS. Complying with the AUA guidelines may reduce morbidity and medical costs.

    Full Text Available AIMS: This study investigated the possible association between hs-CRP as well as hs-CRP changes and rhythm outcome after AF catheter ablation. METHODS: We studied 68 consecutive patients with AF undergoing catheter ablation. hs-CRP levels were measured using commercially available assays before and 6 months after catheter ablation. Serial 7-day Holter ECGs were used to detect AF recurrences. RESULTS: Early AF recurrence (ERAF, within one week was observed in 38%, while late AF recurrence (LRAF, between 3 and 6 months occurred in 18% of the patients. None of the baseline clinical or echocardiographic variables was predictive of ERAF or LRAF. Baseline hs-CRP measured 2.07 ± 1.1 µg/ml and was not associated with ERAF and LRAF. At 6 months, hs-CRP levels were comparable with baseline values (2.14±1.19 µg/ml, p = 0.409 and were also not related with LRAF. However, patients with LRAF showed an hs-CRP increase from 2.03 ± 0.61 to 2.62 ± 1.52 µg/ml (p = 0.028. Patients with an hs-CRP change in the upper tertile (>0.2 µg/ml had LRAF in 32% as opposed to 11% (p = 0.042 in patients in the lower (<-0.3 µg/ml or intermediate (-0.3-0.2 µg/ml tertile. CONCLUSIONS: Changes in hs-CRP but not baseline hs-CRP are associated with rhythm outcome after AF catheter ablation. This finding points to a link between an inflammatory response and AF recurrence in this setting.

    There is little published evidence regarding whether heparin lock solutions containing preservatives prevent catheter-related infections. However, adverse effects from preservative-containing flushes have been documented in neonates, leading many hospitals to avoid their use altogether. Infection control records from 1982 to 2008 at St. Jude Children's Research Hospital (SJCRH) were reviewed regarding the incidence of catheter-related infections and the use of preservative-containing intravenous locks. In addition, the antimicrobial activities of heparin lock solution containing the preservatives parabens (0.165%) or benzyl alcohol (0.9%), and 70% ethanol were examined against Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, Bacillus cereus, Pseudomonas aeruginosa and Candida albicans, and compared with preservative-free saline with and without heparin. Growth was assessed after exposure to test solutions for 0, 2, 4 and 24h at 35 °C. The activities of preservatives were assessed against both planktonic (free-floating) and sessile (biofilm-embedded) micro-organisms using the MBEC Assay. Infection control records revealed two periods of increased catheter-related infections, corresponding with two intervals when preservative-free heparin was used at SJCRH. Heparin solution containing preservatives demonstrated significant antimicrobial activity against both planktonic and sessile forms of all six microbial species. Ethanol demonstrated the greatest antimicrobial activity, especially following short incubation periods. Heparin lock solutions containing the preservatives parabens or benzyl alcohol, and 70% ethanol demonstrated significant antimicrobial activity against both planktonic and sessile micro-organisms commonly responsible for catheter-related infections. These findings, together with the authors' historical infection control experience, support the use of preservatives in intravenous lock solutions to reduce catheter related infections

    Pseudomonas aeruginosa is a multifaceted pathogen causing a variety of biofilm-mediated infections, including catheter-associated urinary tract infections (CAUTIs). The high prevalence of CAUTIs in hospitals, their clinical manifestations, such as urethritis, cystitis, pyelonephritis, meningitis, urosepsis, and death, and the associated economic challenges underscore the need for management of these infections. Biomaterial modification of urinary catheters with two drugs seems an interesting approach to combat CAUTIs by inhibiting biofilm. Previously, we demonstrated the in vitro efficacy of urinary catheters impregnated with azithromycin (AZM) and ciprofloxacin (CIP) against P. aeruginosa Here, we report how these coated catheters impact the course of CAUTI induced by P. aeruginosa in a murine model. CAUTI was established in female LACA mice with uncoated or AZM-CIP-coated silicone implants in the bladder, followed by transurethral inoculation of 10(8) CFU/ml of biofilm cells of P. aeruginosa PAO1. AZM-CIP-coated implants (i) prevented biofilm formation on the implant's surface (P ≤ 0.01), (ii) restricted bacterial colonization in the bladder and kidney (P < 0.0001), (iii) averted bacteriuria (P < 0.0001), and (iv) exhibited no major histopathological changes for 28 days in comparison to uncoated implants, which showed persistent CAUTI. Antibiotic implants also overcame implant-mediated inflammation, as characterized by trivial levels of inflammatory markers such as malondialdehyde (P < 0.001), myeloperoxidase (P < 0.05), reactive oxygen species (P ≤ 0.001), and reactive nitrogen intermediates (P < 0.01) in comparison to those in uncoated implants. Further, AZM-CIP-coated implants showed immunomodulation by manipulating the release of inflammatory cytokines interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and IL-10 to the benefit of the host. Overall, the study demonstrates long-term in vivo effectiveness of AZM-CIP-impregnated catheters, which may

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

    Biofilm formation by Staphylococcus epidermidis is a cause of infections related to peritoneal dialysis (PD). We have used a PD catheter flow-cell model in combination with confocal scanning laser microscopy and atomic force microscopy to study biofilm formation by S. epidermidis. Adherence...... to serum-coated catheters was four times greater than to uncoated ones, suggesting that S. epidermidis binds to serum proteins on the catheter surface. Pseudomonas aeruginosa biofilm supernatant interfered with the formation of a serum protein coat thereby reducing the capacity for biofilm formation in S...

    The 3SITES study randomly assigned a nontunneled central venous catheter site in over 3000 adults treated in intensive care units. 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.

    The purpose of this study was to determine the incidence and risk factors of infections associated with implantable venous access ports (IVAPs.) From August 2003 through November 2011, 1747 IVAPs were placed in our interventional radiology suite. One hundred forty four IVAPs were inserted in patients with hematologic malignancy and 1603 IVAPs in patients with solid tumors. Among them, 40 ports (23 women and 17 men; mean age, 57.1 years; range, 13-83) were removed to treat port-related infections. We evaluated the incidence of port-related infection, patient characteristics, bacteriologic data, and patient progress. Univariable analyses (t test, chi-square test, and Fisher's exact test) and multiple logistic regression analyses were used to determine the risk factors for IVAP related infection. Overall, 40 (2.3%) of 1747 ports were removed for symptoms of infection with an incidence rate of 0.067 events/1000 catheter-days. According to the univariable study, the incidences of infection were seemingly higher in the patients who received the procedure during inpatient treatment (p = 0.016), the patients with hematologic malignancy (p = 0.041), and the patients receiving palliative chemotherapy (p = 0.022). From the multiple binary logistic regression, the adjusted odds ratios of infection in patients with hematologic malignancies and those receiving palliative chemotherapy were 7.769 (p = 0.001) and 4.863 (p = 0.003), respectively. Microorganisms were isolated from 26 (65%) blood samples, and two of the most causative organisms were found to be Staphylococcus (n = 10) and Candida species (n = 7). The underlying hematologic malignancy and the state of receiving palliative chemotherapy were the independent risk factors of IVAP-related infection.

    Catheter coatings have the potential to decrease infection and thrombosis in patients with chronic dialysis catheters. We report our midterm experience with a heparin-coated dialysis catheter. This retrospective, case-control study was approved by our Institutional Review Board. A total of 88 tunneled dialysis catheters were inserted over a 13-month period via the internal jugular vein. Thirty-eight uncoated split-tip catheters and 50 heparin-coated catheters were inserted. Primary catheter patency was compared between the two groups using the log rank test, with infection and/or thrombosis considered as catheter failures. Dialysis parameters during the first and last dialysis sessions, including pump speed, actual blood flow, and arterial port pressures, were compared using unpaired t-tests. Primary patency of the uncoated catheters was 86.0 +/- 6.5% at 30 days and 76.1 +/- 8.9% at 90 days. Primary patency of heparin-coated catheters was 92.0 +/- 6.2% at 30 days and 81.6 +/- 8.0% at 90 days (p = 0.87, log rank test). Infection requiring catheter removal occurred in four patients with uncoated catheters and two patients with heparin-coated catheters (p = 0.23). Catheter thrombosis requiring catheter replacement or thrombolysis occurred in one patient with an uncoated catheter and two patients with heparin-coated catheters (p = 0.9). No differences in catheter function during hemodialysis were seen between the two groups. In conclusion, the heparin-coated catheter did not show a significantly longer patency compared to the uncoated catheter. The flow characteristics of this device were comparable to those of the conventional uncoated catheter. A demonstrable benefit of the heparin-coated catheter in randomized trials is needed before a recommendation for routine implementation can be made.

    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.

    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 technique for right-sided infraclavicular subclavian venous catheterisation.

    Full Text Available Background: Coagulopathy after living donor hepatectomy (LDH may endanger donor safety during removal of thoracic epidural catheter (TEC. The present study was conducted to evaluate the extent and duration of immediate postoperative coagulopathy after LDH. Materials and Methods: A retrospective analysis of perioperative record of LDH over three years was conducted after IRB approval. Variables such as age, gender, BMI, ASA classification, liver volume on CT scan, preoperative and postoperative INR, platelet count (PC and ALT of each donor for five days was noted. In addition, duration of surgery, remnant as percentage total liver volume (Remnant%, blood loss, day of peak in PC and INR were also noted. Coagulopathy was defined as being present if INR exceeded 1.5 or platelet count fell below 1 × 10 5 /mm 3 on any day. Data was analyzed using SPSS 20 for Windows. Between group comparison was made using the Student ′t′ test for continuous variables and chi square test for categorical variables. Univariate analysis was done. Multiple logistic regression analysis was used to find independent factor associated with coagulopathy. Results: Eighty four (84 donors had coagulopathy on second day (mean INR 1.9 ± 0.42. Low BMI, % of remnant liver and duration of surgery were independent predictors of coagulopathy. Right lobe hepatectomy had more coagulopathy than left lobe and low BMI was the only independent predictor. There was no correlation of coagulopathy with age, gender, blood loss, presence of epidural catheter, postoperative ALT or duration of hospital stay. High INR was the main contributor for coagulopathy. Conclusions: Coagulopathy is seen after donor hepatectomy. We recommend removal of the epidural catheter after the fifth postoperative day when INR falls below 1.5.

    Hemodialysis (HD) catheters are prone to thrombotic occlusion. We evaluated tenecteplase, a thrombolytic, for the treatment of dysfunctional HD catheters. Patients with tunneled HD catheters and blood flow rate (BFR) tenecteplase (2 mg/lumen) for a 1 h intracatheter dwell. Treatment success was defined as BFR ≥ 300 mL/min and a ≥ 25 mL/min increase from baseline BFR, 30 min before and at the end of HD. Patients without treatment success at the end of the initial visit received another 2 mg dose of tenecteplase for an up to 72 h extended dwell. Of 223 enrolled patients, 34% (95% confidence interval [CI], 28-40%) had treatment success after a 1 h dwell. Mean (standard deviation [SD]) BFR change from baseline was 82 (124) mL/min. Treatment success in those who received extended-dwell tenecteplase (n = 116) was 49% (95% CI, 40-58%), with mean (SD) BFR change from baseline of 117 (140) mL/min. Reported targeted adverse events included five catheter-related bloodstream infections and one thrombosis. No intracranial hemorrhage, major bleeding, embolic events, or catheter-related complications were reported. Tenecteplase administered as a 1 h or 1 h plus extended dwell was associated with improved HD catheter function in the TROPICS 4 trial.

    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.

    Catheter-associated urinary tract infections (CAUTIs) are the most common hospital-acquired infections. The purpose of this quality improvement (QI) project was to successfully implement a nurse-led evidence-based practice change designed to reduce CAUTIs in a cardiac intensive care and step-down unit. The QI project was implemented using a convenience sample of patients admitted to the cardiac intensive care and step-down unit.Evaluation data were collected 3 months preimplementation and 9 months postimplementation. We used Wick's Check-Plan-Do-Check-Act model of continuous QI to guide the project. A statistically significant change in the number of CAUTIs (P = .009) and CAUTI occurrences (P = .005) was observed following the intervention. The number of indwelling catheter days and indwelling catheter utilization did not significantly differ following implementation of the intervention. Nurse compliance with the intervention was computed for each month; the average compliance rate was 91%. Findings from this project indicate that a nurse-led evidence-based practice project exerted a positive influence on CAUTI occurrences.

    Infective complications following induced abortions are still a common cause of morbidity and mortality. This review focusses on defining the strategies to improve care of women seeking an induced abortion and to reduce infective complications. We have considered the evidence for screening and cost-effectiveness for antibiotic prophylaxis. Current evidence suggests that treating all women with prophylactic antibiotics in preference to screening and treating is the most cost-effective way of reducing infective complications following induced abortions. The final strategy to prevent infective complications should be individualized for each region/area depending on the prevalence of organisms causing pelvic infections and the resources available.

    To evaluate the efficacy and safety of fluoroscopy-guided, radiologic placement of a tunneled central venous catheter into the superior vena cava (SVC). Thirty five patients underwent tunneled central venous catheter placement to facilitate long-term chemotherapy. They included 33 leukemic patients, one colon cancer patient, and one multiple myeloma patient. After confirming central venous patency with a injection of contrast media via the peripheral cephalic or basilic vein in the wrist joint, the subclavian vein was punctured under fluoroscopic guidance. A 7F double lumen TPN catheter was placed into the SVC through a subcutaneous tunnel in the anterior chest wall. Catheter placements were successful in all patients. The mean procedure time was 17.2minutes, mean fluooscopy time was 1.3minutes, mean number of punctures was 1.4, and mean volume of injhected contrast media was 43.5cc. Only two of all leukemic patients developed mild hematomas at the puncture site, but these soon resolved themselves. None of the patients developed pneumothorax or hemothorax. But late complications included local infection in two patients (6%) and thrombotic occlusion of the catheter in one (3%). The occluded catheter was successfully recanalized with Urokinase infusion. Fluoroscopy-guided, radiologic placement of a tunneled central venous catheter is an easy and safe method, and useful for patients requiring long-term venous access.

    Full Text Available Implantation of peritoneal dialysis (PD catheters via the laparoscopic technique is expanding, but none of the studies concerning this technique have compared its outcome with the percutaneous insertion done by the nephrologist. We compared the technical survival and outcome of 52 PD catheters placed in 43 patients with end-stage renal disease (ESRD in our center from March 2006 to October 2007. Of these, 27 PD catheters were inserted percutaneously by a nephrologist (group 1 and 25 were placed by a surgeon using the conventional laparoscopic technique (group 2. Very obese patients, those with previous abdominal surgery, and those who refused local anesthesia were excluded from the study. All catheters were evaluated for mechanical and infectious complications and the overall technique survival was analyzed. The incidence of complications in PD catheters did not largely differ between the two groups. Early catheter-related infection episodes (within two weeks of catheter placement occurred in three of 22 (13.6% patients in group 1, versus three of 21 (14.3% patients in group 2 (P >0.05. The incidence of exit site leak was higher in group 2 (19.0% compared to (4.5% group 1 (P 0.05. We conclude that in our study, the percutaneous bedside placements of PD catheters done by nephrologists were comparable with the laparoscopic insertions performed by surgeons where the high-risk patients were avoided, and the former provided a safer and more reliable access that allowed a rapid initiation of PD.

    Purpose: To determine the patency rates of and factors associated with increased risk of patency failure in patients with femoral vein tunneled hemodialysis catheters. Methods: All femoral tunneled catheter insertions from 1996 to 2006 were reviewed, during which time 123 catheters were inserted. Of these, 66 were exchanges. Patients with femoral catheter failure versus those with femoral catheter patency were compared. Confounding factors, such as demographic and procedural factors, were incorporated and assessed using univariate and multivariable Cox proportional hazards regression analyses. Results: Mean catheter primary patency failure time was 96.3 days (SE 17.9 days). Primary patency at 30, 60, 90, and 180 days was 53.8%, 45.4%, 32.1%, and 27.1% respectively. Crude rates of risk of catheter failure did not suggest a benefit for patients receiving catheters introduced from one side versus the other, but more cephalad location of catheter tip was associated with improved patency. Multivariate analysis showed that patients whose catheters were on the left side (p = 0.009), were of increasing age at the time of insertion (p = 0.002) and that those who had diabetes (p = 0.001) were at significantly greater risk of catheter failure. The catheter infection rate was 1.4/1000 catheter days. Conclusion: Patients who were of a more advanced age and had diabetes were at greater risk of femoral catheter failure, whereas those who received femoral catheters from the right side were less at risk of catheter failure.

  20. A Retrospective Study of Preferable Alternative Route to Right Internal Jugular Vein for Placing Tunneled Dialysis Catheters: Right External Jugular Vein versus Left Internal Jugular Vein.

    Directory of Open Access Journals (Sweden)

    Pei Wang

    Full Text Available Right internal jugular vein (IJV is a preferred access route for tunneled (cuffed dialysis catheters (TDCs, and both right external jugular vein (EJV and left IJV are alternative routes for patients in case the right IJV isn't available for TDC placement. This retrospective study aimed to determine if a disparity exists between the two alternative routes in hemodialysis patients in terms of outcomes of TDCs.49 hemodialysis patients who required TDCs through right EJV (n = 21 or left IJV (n = 28 as long-term vascular access were included in this study. The primary end point was cumulative catheter patency. Secondary end points include primary catheter patency, proportion of patients that never required urokinase and incidence of catheter-related bloodstream infections (CRBSI.A total of 20,870 catheter-days were evaluated and the median was 384 (interquartile range, 262-605 catheter-days. Fewer catheters were removed in the right EJV group than in the left IJV group (P = 0.007. Mean cumulative catheter patency was higher in the right EJV group compared with the left IJV group (P = 0.031. There was no significant difference between the two groups in the incidence of CRBSI, primary catheter patency or proportion of patients that never required urokinase use. Total indwell time of antecedent catheters was identified as an independent risk factor for cumulative catheter patency by Cox regression hazards test with an HR of 2.212 (95% CI, 1.363-3.588; p = 0.001.Right EJV might be superior to left IJV as an alternative insertion route for TDC placement in hemodialysis patients whose right IJVs are unavailable.

    has been used since the beginning of 1980. Patients with chronic pain, who does not get relief with medication through other accesses are benefited with infusion of opiate associated to a local anesthetic through epidural access. However, there are still doubts on the efficacy of the method in the handling and, consequently, over the risk for infection and other complications. As nursing is fundamental to make effective the relieve pain treatment, this study proposes to demonstrate how to keep safe the technique. Twenty-seven patients with chronic pain using epidural catheter for 18 days were followed between 2002 and 2004. Catheters were implanted in thoracic or lumbar level. No complications like epidural abscess, meningitis our epidural haematoma were observed. Patients' satisfaction related to analgesia was evident.

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

    Full Text Available Hemodialysis (HD catheters are commonly used as temporary vascular access in patients with kidney failure who require immediate HD. The use of these catheters is limited by complications such as infections, thrombosis resulting in poor blood flow. We studied the complications and outcomes of nontunneled catheters used for vascular access in our dialysis unit. The records of all patients, with renal failure who were dialyzed over a two-year period and had a double lumen nontunneled catheter inserted, were retrieved. Catheter insertion was carried out under ultrasound guidance using the modified Seldinger technique. The demographic data of patients, etiology of chronic kidney disease, and complications and outcomes of these catheters were noted. Fifty-four patients with mean age 43.7 ± 15.8 years had 69 catheters inserted for a cumulative total of 4047 catheter-days. The mean catheter patency was 36.4 ± 37.2 days (range: 1-173 days. Thrombosis occluding the catheters was the most common complication and occurred in 58% of catheters leading to catheter malfunction, followed by infections in18.8% of catheters. During follow-up, 30 (43.5% catheters were removed, 14 (20.3% due to catheter malfunction, eight (11.6% due to infection, five (7.2% elective removal, and three (4.3% due to damage. Thrombotic occlusion of catheters was a major limiting factor to the survival of HD catheters. Improvement in catheter patency can be achieved with more potent lock solutions.

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

    Full Text Available Abstract Background Antimicrobial catheters have been utilized to reduce risk of catheter colonization and infection. We aimed to determine if there is a greater than expected risk of microorganism-specific colonization associated with the use of antimicrobial central venous catheters (CVCs. Methods We performed a meta-analysis of 21 randomized, controlled trials comparing the incidence of specific bacterial and fungal species colonizing antimicrobial CVCs and standard CVCs in hospitalized patients. Results The proportion of all colonized minocycline-rifampin CVCs found to harbor Candida species was greater than the proportion of all colonized standard CVCs found to have Candida. In comparison, the proportion of colonized chlorhexidine-silver sulfadiazine CVCs specifically colonized with Acinetobacter species or diphtheroids was less than the proportion of similarly colonized standard CVCs. No such differences were found with CVCs colonized with staphylococci. Conclusion Commercially-available antimicrobial CVCs in clinical use may become colonized with distinct microbial flora probably related to their antimicrobial spectrum of activity. Some of these antimicrobial CVCs may therefore have limited additional benefit or more obvious advantages compared to standard CVCs for specific microbial pathogens. The choice of an antimicrobial CVC may be influenced by a number of clinical factors, including a previous history of colonization or infection with Acinetobacter, diphtheroids, or Candida species.

    Objective To realize the status and causes of catheter-associated nosocomial infection (CANI) in surgical intensive care unit (SICU) , so as to decrease the incidence by taking proper measures. Methods Six hundred and fifteen patients with catheters in SICU between 2005 and 2009 were monitored prospectively, including the occurrence of CANI, patients' age, length of hospital stay, invasive procedures, and pathogens. Results One hundred and ninety-seven of 615 patients (32. 03%) developed CANI, and CANI rate was 2. 60%, 12. 85% and 56. 40% in patients with 1 kind, 2 or 3 kinds of catheters simultaneously respectively, there were significant difference among three groups (x2 = 151.55, P<0. 001). The rate of ventilator-associated pneumonia (VAP), catheterassociated urinary tract infection (CA-UTI) , and central venous catheter (CVC)-associated bloodstream infection (CVC-BSI) per 1 000 catheter days was 15. 51, 13. 70 and 5. 79 respectively. The average catheter utilization days before the occurrence of CANI were as follows: ventilator (12. 22 ± 11.29) days, urinary catheter (13. 09 ± 13. 29)days , CVC (20. 64 ± 18. 39) days respectively. The major pathogen in VAP , CA-UTI and CVC-BSI was Acinetobacter spp. ( 18. 80 %), Candida albicans (36. 46 %) and Acinetobacter spp. ( 18. 75 %) respectively. Conclusion Patients with more catheters , long hospital stay and long duration of catheters are prone to develop nosocomial infection. The key to the prevention of emerging of drug-resistant strain and decrease in NI are strengthening of disinfection and isolation, shortening the time of catheter retaining, implementing hand hygiene, and using antimicrobial drug rationally.%目的 了解外科重症监护室(SICU)导管相关性医院感染发生状况及其原因,以采取相应措施降低其发病率.方法 采用前瞻性监测方法,对SICU 2005-2009年间615例留置导管患者的相关医院感染发生状况、年龄、住院天数、侵人性操作

    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

    Full Text Available Most hematological patients suffer a significant venous damage related to different administrated intravenous therapy, being necessary to place central venous catheters (CVC. CVC is associated with various complications. The most common catheter-related complications are occlusion and infection. To avoid such of them, the development of protocols for insertion and care are needed, as well as recording and following up complications. To this end, we propose a cross-sectional carried out during 13 months whose main goal is to know the incidence of CVC- related complications (mainly occlusion and infection in hematological patients.Population included all the =14 ages patients admitted to different hematological units at Ramon y Cajal and Gregorio Marañón hospitals in Madrid and who signed informed consent. Socio-demographic, clinical characteristics and complications were entered into a log which included a pursuit of care protocol.

    self-locating catheter was removed in more cases due to leaks, peritoneal infections and incorrect function. Survival of the catheters. We did not find differences in the survival of the catheters (Log-Rank Mantel Cox =0,164. Discussion: Self-locating catheters had a higher number of surgical and mechanical complications than the Tenckhoff catheters, with no differences found in respect of infectious complications. We found a lower survival compared to the Tenckhoff catheters without statistical significance. All the data seem to be related with the leaks caused by self-locating catheters since they were placed.

    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.
