Abstract
OBJECTIVES: Assessment of the usefulness of antibiotic prophylaxis in inguinal hernioplasty. MATERIALS AND METHODS: This prospective randomized double blind study was conducted on 98 patients. Group A (50 patients) received a single dose of intravenous amoxicillin and clavulanic acid, and Group P (48 patients) received an equal volume of normal saline placebo by intravenous bolus 30 min before the induction of anesthesia. Hernioplasty was performed with polypropylene mesh. Skin was closed using skin staples that were removed after complete wound healing. The surgical site infection was diagnosed according to APIC, CDC criteria ( http://www.apic.org ). RESULTS: The mean operative time was 38.8 ± 10.8 min in group A versus 40.9 ± 11.1 min in group P (P = 0.34). The mean hospitalization time was 1.3 ± 0.463 days in group A versus 1.25 ± 0.438 days in group P (P = 0.58). Four patients (2%) in group A and 6 patients (2.88%) in group P had wound infections (P = 0.47). Group A had 3 superficial infections and 1 deep infection while group P had 5 superficial infections and 1 deep infection. Antibiotic treatment of the wound infection was successful in all patients. Wound culture showed Staphylococcus aureus infection in 1 patient each group, Streptococcus pyogenes in 1 group A patient and Pseudomonas aeruginosa in 1 group P patient. Cultures in other patients in both groups were reported to be sterile. CONCLUSION:Prophylactic antibiotic usage in patients undergoing tension free inguinal hernioplasty did not show any statistically significant beneficial effects in reduction of surgical site infection.
