SURGICAL SITE INFECTION;

COMPARISON OF FREQUENCY AFTER PRIMARY AND DELAYED PRIMARY CLOSURE IN DIRTY ABDOMINAL WOUNDS.

Abstract

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.
