Objective  To assess the risk factors associated with postoperative infection after elective abdominal operation for elderly in department of general surgery.
Methods  One hundred and fifty-nine consecutive elderly patients admitted to the department of general surgery in our hospital for elective abdominal operation between May 2010 and February 2012 were considered for inclusion and retrospectively analyzed. Thirty-eight patients (23.90%)with postoperative infection were taken as the infection group and 121 patients without postoperative infection as noninfection group. The differences in the objective physiological indicators, subjective health status indicators, operation status, the incidence of postoperative infective complications, and mortality were compared between the two groups.
Results  Of enrolled 159 patients in this study, the incidence of postoperative infective complications was 23.90% (38/159); 2 patients died, and the postoperative mortality rate was 1.26%. Single factor and multivariate logistic regression analysis showed that preoperative malnutrition risk, history of diabetes, and chronic respiratory system disease were the independent risk factors of postoperative infection complications in elective abdominal surgery for elderly patients.
Conclusion  Improving preoperative respiratory function, diabetes mellitus, and nutritional status would help to reduce incidence of postoperative infection for elderly patients with elective abdominal operation.
