Randomized Controlled Trial
Tegaderm™ CHG dressing significantly improves catheter-related infection rate in hemodialysis patients.
Catheter-related infections are an important clinical problem in maintenance hemodialysis patients. Catheter-related bloodstream infections have a negative effect on survival, hospitalization and cost of care. Tegaderm™ chlorhexidine gluconate (CHG) dressing may be useful to reduce catheter-related infection rates. ⋯ This is the first prospective study to show that Tegaderm™ CHG dressing significantly reduces catheter-related infection rates in hemodialysis patients.

Observational Study
Ultrasound-guided supraclavicular central venous catheter tip positioning via the right subclavian vein using a microconvex probe.
The ultrasound-guided central venous catheter (CVC) guidewire tip positioning has been demonstrated for catheterization of the right internal jugular vein. We explored the feasibility of an ultrasound-guided right subclavian vein (RScV) CVC tip positioning via a right supraclavicular approach using a microconvex probe. ⋯ Ultrasound-guided CVC tip confirmation following catheterization of the right subclavian vein via a right supraclavicular approach with a microconvex probe is feasible.

A persistent left superior vena cava (PLSVC) is a rare, under-recognized congenital anomaly. The PLSVC is incidentally discovered during central venous access procedures when access is obtained from the left internal jugular vein. ⋯ This case review presents three cases which illustrate the viability and safety of a PLSVC for long-term central venous access in the setting of chemotherapy and hemodialysis. Ascertaining the drainage pattern of a PLSVC with venogram, echocardiography, computed tomography is paramount prior to long-term catheterization.
