Which actions should be avoided postoperatively following the placement of a chronic peritoneal dialysis catheter?

The recommendation to avoid full-volume dialysate, straining for a bowel movement, and crying postoperatively following the placement of a chronic peritoneal dialysis catheter is grounded in the need to protect the newly placed catheter and the surrounding surgical site.

Using full-volume dialysate puts pressure on the abdominal cavity, which could lead to discomfort, displacement of the catheter, or even complications such as leakage or perforation if the surgical site is not completely healed. Straining for a bowel movement creates increased intra-abdominal pressure, which can further jeopardize the integrity of the catheter's positioning and the surgical repair. Similarly, crying or significant emotional stress can result in muscle tension and abdominal pressure changes that can also be harmful after such a procedure.

Ensuring that patients manage their bowel health through softening agents or gentle laxatives instead of straining is an essential aspect of postoperative care. This helps maintain the position and function of the catheter while allowing the site to heal properly.
