Abstract:

Objective To investigate the risk factors for pulmonary infection following emergency surgery for upper gastrointestinal perforation. Method A total of 350 patients diagnosed with upper gastrointestinal per-foration who underwent emergency surgery at our hospital were analyzed. Based on the presence of postoperative pulmonary infection, the patients were divided into an infection group and a non-infection group. Univariate and multivariate logistic regression analyses were conducted to identify the risk factors for pulmonary infection. Result Univariate analysis revealed that the infection group had a higher proportion of patients with a history of smoking (P ＜ 0.001), hypertension (P=0.008), preoperative gastric tube placement (P ＜ 0.001), shock (P ＜ 0.001), dia-betes (P ＜ 0.001) , and reason for perforation (P=0.004)compared to the non-infection group. Multivariate logistic regression analysis indicated that a history of smoking and hypertension are independent risk factors for pulmonary infection following surgery for upper gastrointestinal perforation (P ＜ 0.05). Conclusion A history of smoking and hypertension are signifi cant risk factors for the occurrence of pulmonary infection after emergency surgery for up-per gastrointestinal perforation.
