Abstract

Objectives: To compare the frequency of surgical site infection after primaryand delayed primary wound closure in dirty abdominal wounds. Study Design: Randomizedcontrolled trial. Duration and Setting: This study was carried out over a period of six monthsfrom 07-02-2014 to 06-08-2014 in the department of surgery combined military hospital Quetta.Methodology: A total of 190 patients were included in this study. wound was observed fordevelopment of surgical site infection post operatively within seven days by the assignedinvestigator who was unaware of the wound study design. surgical site infection was assessedusing Southampton wound grading. Results: Mean age of the patients was 30.89±10.38 and32.74±9.52 in group A and B, respectively. in group-A, 73 patients (76.8%) and in group-B 66patients (69.5%) were male while 22 patients (23.2%) of group-A and 29 patients (30.5%) ingroup-B were female.in group-A surgical site infection was observed in 29 patients (30.5%)and in group-B 12 patients (12.6%) were having surgical site infection. statistically significantdifference was found between two groups (p=0.003). Conclusion: The frequency of surgicalsite infection was significantly lower after delayed primary closure of dirty wounds as comparedto primary closure.
