What is a common cause of dialysate leaks around the catheter insertion site?

• A. Inadequate catheter placement or high intra-abdominal pressure causing leakage.
• B. Infection at the exit site.
• C. Incorrect dialysate potassium.
• D. Overhydration.

Answer: (A)

Dialysate leaks around the catheter insertion site occur most often because the catheter placement isn’t ideal or because intra-abdominal pressure is high. If the catheter isn’t positioned properly, the tissue tract into the peritoneal cavity may not seal well, allowing dialysate to seep out around the skin as the system is filled and dwells. When intra-abdominal pressure rises—due to straining with constipation, coughing, heavy lifting, or large fill volumes—the dialysate is pushed along the catheter tract toward the skin, producing a leak at the insertion site. This scenario is different from an exit-site infection, which causes infected drainage rather than clear dialysate leakage. Options related to dialysate potassium or general fluid status don’t directly cause leaks at the insertion site.
