Objective: To probe into the perioperative prophylaxis and surgical incision infection in children undergoing inguinal hernia repair. Methods: Medical records of 3

851 children undergoing inguinal hernia repair in our hospital from 2011 to 2015 were collected. Based on the retrospective analysis of the situation of prophylactic use of antibiotics in inguinal hernia repair during perioperative period in 2011

the program of No Prophylactic Use of Antibiotics during Perioperative Period of Cleaning Surgery was formulated. The clinicians of general surgery strictly implemented the relevant provisions of the program

monitored the postoperative incision infection

and evaluated the effects of antibiotics on the incision infection of inguinal hernia repair in children during perioperative period. Results: From 2011 to 2015

the prophylactic use rate of antibiotics in inguinal hernia repair during perioperative period were respectively 100.00%

50.06%

0.00%

0.00% and 0.00%. The infection rate of surgical incision were respectively 0.26%

0.26%

0.13%

0.13% and 0.26%

there was no significant difference in the infection rate of surgical incision between 2012 to 2015 and 2011 (P>0.05)

live up to the regulations of Nosocomial Infection Management Standard (Trial) with the infection rate of clean surgical incision <0.5%. Conclusion: Pediatric inguinal hernia repair without prophylactic use of antibiotics will not lead to the increased infections in surgical incision.
