INTRODUCTION: Aerobic bacterial infections often complicate vascular access in patients receiving haemodialysis, leading to Catheter-Related Blood Stream Infections (CRBSI). Various studies report Gram - positive bacteria, Staphylococcus aureus (S. aureus) in particular, as the most common aetiologic agent. Studies on microbiological analysis in this subset of population from India are very few. AIM: To examine clinical and bacteriological profiles of haemodialysis patients developing CRBSI, the antibiotic susceptibility of the bacteria isolated from these patients and determine nasal carriage of S...

BACKGROUND: Using a proper laparoscopic trocar for making a downward rectus sheet tunneling (RSHT) during the implementation of peritoneal dialysis (PD) catheters leads to a longer survival of catheter and less catheter dysfunction. As no specific laparoscopic trocar has been invented for insertion of PD catheters, we designed a new trocar. In this article, we describe specifications of our new invented trocar for the first time. We will describe our experience with it in our patients as well...

BACKGROUND: Cuffed, double-lumen, tunneled haemodialysis catheters are a common means of vascular access in paediatric haemodialysis, particularly in infants. Haemodialysis catheter fracture with distal embolization is a rare complication. CASE REPORT: A 2-year-old boy was receiving chronic haemodialysis via a right internal jugular cuffed, double-lumen, tunneled haemodialysis catheter, inserted 3 months previously. He was asymptomatic and was incidentally found to have had embolization of a fractured catheter tip into a segmental branch of the left pulmonary artery...

PURPOSE: This study compared the patency of a split-tip self-centering catheter with a predesigned curve (CentrosFLO; Merit, Salt Lake City, Utah) and a standard split-tip catheter with straight distal limbs (Medcomp, Harleysville, Pennsylvania) catheter in patients requiring exchange of a dysfunctional tunneled dialysis catheter (TDC). MATERIALS AND METHODS: A single-center retrospective chart review was performed between January 2013 and July 2014. Patients had an existing dysfunctional TDC that was exchanged over a wire using the same access site for either a split-tip self-centering catheter with a predesigned curve or a standard split-tip catheter with straight distal limbs catheter...

BACKGROUND: Suboptimal position of tunneled central venous catheters (Broviacs) decreases long-term catheter longevity, incurring morbidity and cost. We postulated that catheter malposition is related to patient's age, technique used, and initial catheter tip location (CTL). METHODS: We performed a retrospective review with 1-year follow-up of Broviacs placed in patients at our children's hospital from 3/2010 to 10/2013. We defined malposition as a noncentral CTL that required replacement, excluding catheters physically dislodged...

Hemodialysis catheters are vital for chronic renal failure patients. Permanent tunneled dialysis catheters may be inserted through the jugular, subclavian, and femoral veins. In this paper, we aimed to present the computed tomography findings of a chronic renal failure patient who had referred our clinic with abdominal pain and dyspnea symptoms. This patient had a formerly inserted hemodialysis catheter for chronic renal failure and her catheter was found to be extending towards the middle hepatic vein with the tip leaning onto the parenchyma...

BACKGROUND: Central venous catheters (CVCs) play a vital role in the management of acute and chronic illness. Dressings and securement devices must ensure CVCs do not dislodge or fall out, provide a barrier protection from microbial colonisation and infection, and be comfortable for the patient. There is a large range of dressing and securement products available for clinicians to use. OBJECTIVES: To compare the available dressing and securement devices for CVCs, in terms of catheter-related bloodstream infection (BSI), catheter colonisation, entry- and exit-site infection, skin colonisation, skin irritation, failed catheter securement, dressing condition and mortality...

BACKGROUND: The bacterial colonization of hemodialysis catheter occurs frequently and reaches to the catheter-related bloodstream infections (CRBSIs). We hypothesized bacterial colonization promotes inflammation and that might be associated with renal outcome. The aim of this study was to investigate the colonization status for tunneled cuffed dialysis catheter (TCC) and the factors for contributing to the catheter colonization and explore whether bacterial colonization would be related with declining of residual renal function (RRF)...

We are currently in the midst of a worldwide obesity epidemic, including in patients with end-stage kidney disease. Placing hemodialysis catheters is a particular challenge in patients with extreme obesity. Here we describe the merging of two technologies to place catheters in patients who are too heavy (over 225 kg) to be placed safely on a procedure table for fluoroscopic guidance. The first technology is ECG-guided placement of catheters, well established for guidance of peripherally inserted central catheters (PICCs) and tunneled and nontunneled central venous catheters...

The percutaneous catheterization of central veins is increasingly used in nephrological practice as a temporary or permanent vascular access. The aim of our study was to present and to analyze episodes of catheter tip malposition during percutaneous tunneled hemodialysis catheter insertion in the large, unselected group of patients. All patients who underwent the procedure of catheter insertion in our department during year 2012 were analyzed retrospectively. One hundred four tunneled hemodialysis catheters were inserted in 101 patients...

Removal of tunnelled central venous catheters can become complex if left in situ for a prolonged period. We report a challenging case of a stuck tunnelled haemodialysis catheter, which required sternotomy with cardio-pulmonary bypass for retrieval. A 47-year-old female had failed attempts to remove the venous limb of a Tessio line on the ward. A cut down on the internal jugular vein and division of the fibrin sheath failed to release it. Synchronous traction was applied via a snare inserted through a femoral approach...

PURPOSE: Recently, there have been many reports that exact central vein catheter tip positioning was possible using intracardiac electrocardiographic (ECG) monitoring. Ultrasonic guidance in combination with intracardiac ECG monitoring may allow for a tunneled dialysis catheter to be inserted at the bedside without using fluoroscopy. Therefore we report on the intracavitary ECG method for insertion of a tunneled dialysis catheter with ultrasound guidance and the feasibility, safety, effectiveness, complications and limitations of this method...

BACKGROUND: Proper placement of central venous catheter (CVC) tip could reduce early and late catheter-related complications. Although the live fluoroscopy is standard of care for placement of the catheter, it is not available in many centers. Therefore, the present study evaluated the sensitivity and specificity of bedside chest X-ray (CXR) for proper positioning of the catheter tip. MATERIALS AND METHODS: A total of 82 adult patients undergoing elective placement of tunneled CVC were enrolled in this study during 2010-2012...

Although guidelines recommend catheters as a last resort for establishing a vascular access in patients undergoing dialysis, they continue to be used widely for this purpose. Catheter-related atrial thrombus (CRAT) is rarely reported in this group of patients, and it can lead to serious complications. The aim of this study was to determine the incidence of CRAT in patients undergoing hemodialysis with permanent-tunneled catheters. A total of 50 patients undergoing hemodialysis with permanent catheters were included in this study...
