Antibiotic prophylaxis in percutaneous endoscopic gastrostomy.
(Clinical Trial;Journal Article)
OBJECTIVES: The benefit of antibiotic prophylaxis in percutaneous endoscopic gastrostomy is controversial. The aim of this study is to determine whether prophylactic antibiotic treatment with Cefazolin reduces the incidence of peristomal infection after percutaneous endoscopic gastrostomy. METHODS: Of the 131 hospitalized or nursing home patients referred for percutaneous endoscopic gastrostomy, 115 were enrolled in a prospective randomized double-blind placebo controlled trial. Sixty-one (group 1) were randomized in a double-blind fashion and received either Cefazolin or saline pregastrostomy. Fifty-four patients (group 2) were on antibiotics for prior medical indications pregastrostomy. Patients had their peristomal area evaluated on a daily basis for 1 wk after gastrostomy. Erythema and exudate were scored on a scale from 0 to 4; induration was scored on a scale of 0 to 3; a maximum score of 8 or higher or the presence of pus was criteria for infection. RESULTS: Wound infection occurred in 4 of 30 (13%) participants receiving Cefazolin and in 6 of 31 (19%) participants receiving saline (p > 0.5). In the 54 patients on antibiotics for prior indications, wound infection was observed in 2 subjects (3%). This finding was a significant difference when compared with the placebo group (p < 0.02). CONCLUSIONS: A single dose of Cefazolin prophylaxis does not reduce the overall peristomal wound infection in percutaneous endoscopic gastrostomy. Patients receiving prior extended antibiotic therapy have fewer peristomal wound infections.
