Catheter Related Complications

This prospective observational study evaluates the feasibility, technical success, safety, and clinical outcomes of ultrasound-guided percutaneous peritoneal dialysis (PD) catheter insertion for urgent-start dialysis in pediatric patients with acute kidney injury (AKI). Acute kidney injury in children frequently requires prompt renal replacement therapy. While traditional surgical placement of peritoneal dialysis catheters often requires general anesthesia and an extended waiting period before use, percutaneous insertion under real-time ultrasound guidance using a modified Seldinger technique allows for bedside placement under local anesthesia and rapid initiation of dialysis. The study includes 50 pediatric patients (ranging from neonates up to 18 years of age) admitted to Assiut University Hospitals who require urgent renal replacement therapy and are candidates for peritoneal dialysis. Participants undergo percutaneous catheter placement guided in real time by ultrasound, followed by the initiation of an urgent-start dialysis protocol. The primary focus is to determine the technical success of the insertion procedure, evaluate catheter function and short-term catheter survival, and record procedure-related complications such as bleeding, dialysate leakage, infection, and mechanical malfunction. Secondary objectives include assessing renal recovery, patient survival to hospital discharge, and the need for conversion to alternative dialysis modalities.

The goal of this clinical trial is to compare a chlorhexidine antimicrobial barrier cap in patients requiring hemodialysis treatment to the standard hemodialysis caps currently used within the Metro North Kidney Health Service. The main questions to answer are: * Study Feasibility * Occurrence of infectious complications related to renal central venous catheters Participants will be randomly allocated to receive either of the below hemodialysis caps to cover their hemodialysis catheter hub: * The standard hemodialysis cap used at the Royal Brisbane and Women's Hospital, or * The intervention hemodialysis cap containing chlorhexidine inside it Researchers will compare standard and chlorhexidine hemodialysis caps to see if the presence of chlorhexidine improves the occurrance of infectious complications related to the hemodialysis catheter.
