Impact of using prophylactic antibiotic on prevention of wound infection in inguinal herniorrhaphy

ABSTRACT

To compare the effect of antibiotic prophylaxis with placebo in prevention of wound infection amongst patients undergoing clean open inguinal herniorrhaphy [without mesh]. Randomized Controlled Trial. Pakistan Air Force Hospital, Faisal Base Karachi from October 2009 to November 2011. One hundred and fifty patients undergoing inguinal herniorrhaphy were included and randomly assigned to one of the two groups using random numbers table. Group A patients were given intravenous antibiotic while those in Group B were given equal volume of normal saline just before the induction of anaesthesia. Patients from both groups were observed for the presence of wound infection. Total seven cases [4.7%] of surgical site infection were detected; two cases [2.7%] occurred in group A whereas five cases [6.7%] occurred in group B. The low frequency of post-operative wound infection was seen in group A as compared to group B but the difference was statistically insignificant. Antibiotic prophylaxis has no significant effect on prevention of wound infection in inguinal herniorrhaphy
