Risk factors and pathogens of wound infectionin patients with acute intestinal obstruction after emergency operation

Abstract

Objective To investigate risk factors and pathogens of wound infectionin patients with acute intestinal obstruction after emergency operation. Methods From January 2013 to May 2016, 193 cases of acute intestinal obstruction were treated by emergency operation in Yichang Second People's Hospital of Hubei Province.There were 39 cases of incision infection (infection group) and 154 cases of non incision infection (control group).The pathogenic bacteria were detected in the infected group, and compared the clinical data of the two groups. Results In the thirty-nine cases of incision infection after operation, one kind of bacterial infections in 24 cases (61.54%), two kind of bacterial infections in 12 cases (30.77%), three kinds of bacterial infections in 3 cases (7.69%). Fifty-seven kinds of bacteria were mainly Escherichia coli, Klebsiella pneumoniae, etc. In the observation group, ≥60 years old proportion, the proportion of III class incision, operation time≥120 min, the proportion of blood obstruction and diabetes rates were 58.97%, 51.28%, 56.41%, 12.82% and 82.05%, significantly higher than the control group, the difference was statistically significant (2=9.812, 14.710, 10.718, 9.258 and 35.187, P 0.05).The results of Logistic regression analysis showed: age, ≥60 years, diabetes mellitus, III class incision and the operation time≥120 min were risk factors of incision infection with acute intestinal obstruction after operation (OR=6.184, 22.220, 7.807 and 1.721, P< 0.05). Conclusion In view of the risk factors of postoperative wound infection in patients with acute intestinal obstruction, we should take various measures to reduce the incidence of infection.
