AIM: To identify the risk factors for postoperative pulmonary complications (PPC) after gastrointestinal surgery.METHODS: A total of 1 002 patients undergoing gastrointestinal surgery in the Second Affiliated Hospital, Sun Yat-Sen University, during December 1999 and December 2003, were retrospectively studied.RESULTS: The overall incidence of PPC was 22.8% (228/ 1 002). Multivariate logistic analysis identified nine risk factors associated with PPC, including age odds ratio (OR = 1.040) history of respiratory diseases (OR = 2.976),serum albumin (OR = 0.954), chemotherapy 2 wk before operation (OR = 3.214), volume of preoperative erythrocyte transfusion (OR = 1.002), length of preoperative antibiotic therapy (OR = 1.072), intraoperative intratracheal intubation (OR = 1.002), nasogastric intubation (OR = 1.050) and postoperative mechanical ventilation (OR = 1.878). Logistic regression equation for predicting the risk of PPC was P(1) = 1/[1+e-(-3.488+ 0.039× Y+1.090×Rd+0.001×Rbc-0.047×Alb+0.002×Lii+0.049×Lni+0.630×Lmv+0.070×Dat+ 1.168×Ct)].CONCLUSION: Old patients are easier to develop PPC.
