Chronic peritoneal dialysis has been gaining greater popularity in the management of chronic renal failure. It provides the patient greater freedom and mobility with less dependence on the dialysis center. A catheter that penetrates the skin, traverses the soft tissue of the abdominal wall, and lies in the peritoneal cavity permits the exchange of dialysate. However, chronic percutaneous access has been associated with infectious complications, limiting its acceptance and application. Peritonitis caused by intraluminal contamination frequently responds to antibiotic therapy. Infection of the skin and soft tissue of the abdominal wall in the tunnel of the catheter has been a far more serious problem, and the problem necessitating catheter removal in the majority of instances. Pericatheter infection along the tunnel comes from two sources — the peritoneum and the skin. Cuffs, most commonly made of Dacron velour, have been relatively effective in scaling the peritoneal end of the catheter. The skin or catheter exit site has been the more difficult area to manage. Most catheters require significant, and often time-consuming, exit-site care to minimize infection. This is because smooth-surfaced devices or catheters permit epidermal migration along the catheter, which typically results in a sinus tract — a gap between the catheter and the skin. This sinus provides the moist and repetitively traumatized environment in which infection with tissue invasion begins.
