Risk factors of surgical incision infection in patients with gastrointestinal perforation / 中华全科医师杂志

ABSTRACT

The clinical data of 288 patients with gastrointestinal perforation undergoing surgical treatment from Jul 2014 to Jul 2017 were retrospectively analyzed,among whom the surgical incision infection occurred in 112 patients(38.9％).The risk factors of the incision infections were examined with logistic regression analysis.The univariate analysis showed that preoperative albumin level (≤30 g/L),body mass index (＞24.0 kg/m2),duration of abdominal pain(＞24 h),extension of incision,preoperative shock,colostomy,preoperative antibiotic use and the operation time were associated with incision infections(P＜0.05),while the gender,age,preoperative hemoglobin level,diabetes,incision length were not associated with the incision infections(P＞0.05).The multivariate logistic regression analysis showed that the body mass index(OR=1.61,P＜0.01),gastrointestinal perforation site(colon and rectum,OR=5.60,P＜0.01),extension of incision (OR=3.94,P＜0.01) and operation time(OR=1.04,P=0.02)were independent risk factors of theincision infection.The results suggest that the full preoperative preparation,intensive treatment of underlying diseases,avoiding incision extension and shortening operation time may be able to reduce the surgical incision infections for patients with the gastrointestinal perforation.
