Epidural catheter placement offers flexibility in block management. However, during epidural catheter insertion, complications such as paresthesia and venous and subarachnoid cannulation may occur, and suboptimal catheter placement can affect the quality of anesthesia. We performed this prospective, randomized, double-blind study to assess the effect of a single-injection dose of ...

BACKGROUND: Reduction in the rates of major complications such as infection and thrombosis that limit the lifespan of hemodialysis (HD) catheters could conceivably lead to improved survival of "temporary" non-tunneled HD catheters (NTCs). This study was designed to evaluate the impact of the "locking"' of a broad-spectrum antibiotic-cefotaxime with heparin, ...

BACKGROUND: Corporate performance-improvement methodologies can outperform traditional ones in addressing ICU-based adverse events. My colleagues and I used Six Sigma methodology to address our catheter-related bloodstream infection (CR-BSI) rate, which considerably exceeded the nationally established median over a 9-year period. We hypothesized that use of Six Sigma methodology would result ...

OBJECTIVE: Peritoneal dialysis (PD) as an equivalent to hemodialysis (HD) is one renal replacement therapy (RRT), which has several advantages compared to hemodialysis. However, most nephrologists are reluctant to apply this method. The purpose of this study is to assess the catheter efficiency, survival rate and complications of PD catheter ...
Falk Abigail - - 2005
Many clinicians believe that de novo access is required when converting temporary hemodialysis (HD) catheters to long-term or permanent catheters. However, since vascular access sites are at a premium in the dialysis patient, it is important to preserve existing central venous catheters and conserve future access sites. In this retrospective ...

INTRODUCTION: Physicians who perform urethroplasty have varying opinions about when the urinary catheter should be removed post-operatively, but research on this subject has not yet appeared in the literature. We performed voiding cystourethrogram (VCUG) on our anterior urethroplasty patients on days 3 (anastomotic) and 7 (buccal) in an effort to ...

Percutaneous cholecystostomy (PC) using a pigtail catheter is performed on high-risk patients with acute cholecystitis as their general condition does not usually allow them to undergo a "definite" cholecystectomy. However, this method of PC is time-consuming and expensive and requires an interventional radiologist and specially designed radiologic equipment. To determine ...

Lacrimal outflow obstruction after severance of the duct is a common problem in facial trauma. Conventional treatments include external dacryocystorhinostomy, endoscopic-assisted dacryocystorhinostomy, conjunctivorhinostomy, and a Jones tube bypass. However, the disadvantages of these methods are that the procedures are complicated and there is a high rate of recurrence. From April ...

Internal jugular venous catheters (IJVC) for hemodialysis are a commonly employed temporary vascular access for hemodialysis. Most hospitals still follow the use of blind technique, which uses anatomical landmarks. Even in the most experienced hands this procedure has a variable success rate. Ultrasound guidance can decrease the incidence of periprocedural ...
