Surgical Site Infection; Comparison of Frequency After Primary and Delayed Primary Closure in Dirty Abdominal Wounds.

Abstract

, Irum Saleem 5ABSTRACT… Objectives: To compare the frequency of surgical site infection after primary and delayed primary wound closure in dirty abdominal wounds. Study Design: Randomized controlled trial. Duration and Setting: This study was carried out over a period of six months from 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 for development of surgical site infection post operatively within seven days by the assigned investigator who was unaware of the wound study design. surgical site infection was assessed using Southampton wound grading. Results: Mean age of the patients was 30.89±10.38 and 32.74±9.52 in group A and B, respectively. in group-A, 73 patients (76.8%) and in group-B 66 patients (69.5%) were male while 22 patients (23.2%) of group-A and 29 patients (30.5%) in group-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 significant difference was found between two groups (p=0.003). Conclusion: The frequency of surgical site infection was significantly lower after delayed primary closure of dirty wounds as compared to primary closure.

Surgical Site Infection;

“…Appendectomy is a contamined surgical procedure hence the post operative infective complications are common. 1,2 However, the surgical site infection has declined due to the improved surgical instrumentation, sterilization procedures and antibiotic prophylaxis. In appendectomy, the reported frequency of surgical site infection varies from 1 -20% despite antibiotic prophylaxis.…”
