Hemodialysis catheters infections

Endocarditis refers to infection or inflammation of the endocardium, and various pathogens can be involved in infective endocarditis (IE). Endocarditis is usually caused by bacteremia in patients with risk factors, including IV drug abuse, indwelling central venous or urinary catheters, recent dental infections, and implantable cardiac devices. Pseudomonas aeruginosa ( P. aeruginosa ) is an extremely rare causative organism in IE, predominantly among IV drug users and involving right-sided valves. Left-sided native valve P...

Objective : Hemodialysis (HD) catheter-related bloodstream infections (CRBSIs) are a major complication of long-/short-term catheter. Material and Methods : Patients with HD CRBSIs were identified, and their blood was taken and sent to clinical pathology for culture and sensitivity testing. The inclusion criteria were adults with end-stage renal disease who required urgent HD access in the presence of a central venous catheter (CVC) infection. Results : The most common isolates among the patients with CRBSIs were gram-positive microorganisms (57...

Spurious hyperphosphatemia, also known as pseudo-hyperphosphatemia, refers to artifactually elevated serum phosphate values that do not correspond to their actual systemic levels. Vascular access poses a significant challenge for individuals undergoing hemodialysis (HD) due to chronic kidney disease, primarily attributed to the elevated incidence of complications, such as infections or thrombosis associated with catheter use. To mitigate clotting risk during the inter-dialysis intervals, in recent years, a strategy involving the application of concentrated heparin (recombinant tissue plasminogen activator (rt-PA) e...

OBJECTIVE: To provide theoretical basis for prevention of a Dacron-cuffed catheter related infection (CRI), the risk factors of CRI in hemodialysis patients were systematically evaluated. METHODS: Eight databases, including PubMed, Cochrane library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Database (CBM), Wanfang Database and Chinese Scientific Journal Database (VIP), were searched to screen out literatures related to the risk factors of long-term indwelling a Dacron-cuffed CRI in hemodialysis...

BACKGROUND: Unscheduled dressing changes for central venous lines (CVLs) have been shown to increase the risk of bloodstream infections. OBJECTIVE: The objective of this study is to determine if the use of an innovative dressing change kit reduces the rate of unscheduled dressing changes. METHODS: This pre-post interventional study took place at a large, academic, tertiary care center in metro Detroit, Michigan, the United States. We assessed the impact of the interventional dressing change procedure kit on the rate of unscheduled dressing changes for adult patients who underwent placement of a CVL inclusive of a central catheter, peripherally inserted central catheter, or hemodialysis catheter...

METHODS: Using data from 162 patients who underwent catheter placement between January 2017 and December 2020, postoperative chest X-rays and clinical records were reviewed. Outcomes were assessed based on catheter removal duration and complication incidence...

Most peritoneal dialysis (PD)-associated infections caused by Mycobacterium abscessus (M. abscessus) require a transfer from PD to hemodialysis (HD). Here, we report a pediatric case of exit-site and tunnel infections caused by M. abscessus, for whom PD was continued with catheter replacement, debridement of the infected site, and the administration of multiple antibacterial agents. A 10-year-old boy with end-stage kidney disease secondary to juvenile nephronophthisis with NPHP1 deletion, for whom PD was initiated at the age of 9 years, was admitted to the hospital with complaints of fever, pus at the exit-site of the PD catheter, and poor PD drainage...

INTRODUCTION: Paediatric vascular access is a demanding field. The need for a multidisciplinary team is mandatory in children with end-stage kidney disease (ESKD). Central venous catheters (CVCs) remain the preferred option worldwide. Recent emerging data demonstrated the benefits of using arteriovenous fistulas (AVFs) in the paediatric population for long-term vascular access. The small vessel size in children represents a surgical challenge for vascular access. CASE PRESENTATION: We report three cases from our haemodialysis department and the difficulty in maintaining permanent vascular access...

Hemodialysis continues to be the primary approach for renal replacement therapy. Vascular access (VA), particularly arteriovenous fistula or arteriovenous graft, is the preferred technique for establishing hemodialysis access due to its lower risk of infection and central venous stenosis compared to catheters. The aim of this cross-sectional investigation was to examine hemodialysis nurses' knowledge, confidence, and practices in managing VA in Saudi Arabia. This is an online cross-sectional survey study that was conducted in Saudi Arabia between June and August 2023...

OBJECTIVE: This meta-analysis aimed to elucidate the risk factors contributing to catheter-associated bloodstream infection in hemodialysis patients. METHODS: Comprehensive literature searches were conducted in both English and Chinese databases, which encompassed PubMed, Cochrane Library, Embase, CNKI, Wanfang Data, VIP Database and China Biomedical Literature Database. The search timeframe extended from each database's inception to March 8, 2023. Two independent researchers executed literature screening, data extraction, and quality assessment using the Newcastle-Ottawa Scale...

AIM: This study aimed to assess the predictive role of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and mean platelet volume, on catheter survival in chronic hemodialysis patients, analyzing both infectious and non-infectious complications. METHODS: A retrospective analysis encompassed 1279 tunneled catheter insertion procedures involving 902 patients between March 2014 and October 2018. Patients were categorized into two main groups: (i) initial placement and (ii) exchange...

BACKGROUND: Peritoneal dialysis (PD) catheter related infections continue to be a major cause of morbidity and transfer to hemodialysis (HD) in PD patients. The treatment of tunnel infection (TI) could be challenging, especially when the infection involves the superficial cuff requiring the removal of the catheter. To spare the patient the loss of the catheter and the transfer to HD, several mini-invasive surgical techniques have been proposed as rescue therapy. Furthermore, nowadays, the rapid growth of digital technology has enormously increased the diagnostic sensibility of the echo signal allowing to accurately defines the extent of the infectious process along the PD catheter tunnel...

Patients requiring dialysis are extremely vulnerable to infectious diseases. The high burden of comorbidities and weakened immune system due to uremia and previous immunosuppressive therapy expose the patient on dialysis to more infectious events than the general population. The infectious risk is further increased by the presence of endovascular catheters and implantable cardiologic devices. The former is generally placed as urgent vascular access for dialysis and in subjects requiring hemodialysis treatments without autogenous arteriovenous fistula...

IMPORTANCE: Hemodialysis requires reliable vascular access to the patient's blood circulation, such as an arteriovenous access in the form of an autogenous arteriovenous fistula or nonautogenous arteriovenous graft. This Review addresses key issues associated with the construction and maintenance of hemodialysis arteriovenous access. OBSERVATIONS: All patients with kidney failure should have an individualized strategy (known as Patient Life-Plan, Access Needs, or PLAN) for kidney replacement therapy and dialysis access, including contingency plans for access failure...
