Abstract

Bachground: Peritonitis and exit site (ES) infection are two main complications of peritoneal dialysis. There are some controversies regard to preventive strategies for ES care. In this study we compared peritonitis and ES infection rates in patients with and without dressing.

Materials and methods: This historical cohort study carried out on 72 patients under continuous ambulatory peritoneal dialysis treatment, 54 with dressing versus 18 patients without dressing, followed from October 1, 2010 to March 31, 2011 for peritonitis and ES infection.

Results: A total of 17 episodes of ES infection occurred in 12 patients in dressing group, but no case was seen in no-dressing group (P = 0.02). Twenty-one episodes of peritonitis occurred in 15 patients in both groups (one episode every 20.6 patient-months). In no-dressing group two episodes occurred in only one patient (one episode every 54 patient-months), and in dressing group, 19 episode in 14 patients (one episode every 17.1 patient-months) (P = 0.03). Peritonitis was significantly more frequent in male versus female in overall patients (38% vs. 14%, P = 0.025) and in dressing group (52% vs. 15%, P = 0.003). In dressing group, peritonitis was more frequent in diabetics versus non-diabetics (48% vs. 11%, P = 0.01). Odds ratio for developing peritonitis was 9.4 in dressing group (95% confidence interval [CI] =1.05 - 84.4; P = 0.045), and 4.4 in men (95% CI = 1.26 - 15.19; P = 0.02).

Conclusion: In this study, chronic ES care without dressing was associated with lower risk of peritonitis and ES infection.
