The risk of pulmonary complication after surgery for gallstone disease

Objectives: To identify the risk factors of postoperative pulmonary complica- tions (PPC) after surgery for gallstone disease. Methods: A total of 544 patients undergoing open surgery for gallstone disease were retro- spectively studied. Univariate and multivariate logistic regression were used to analyze each factor. Results: There were 24 factors relating to PPC in univariate logistic analysis. And multi- variate logistic analysis identified 5 independent risk factors associated with PPC, including peri- operative aerosol therapy (OR = 5.906), duration of postoperative antacids therapy (OR = 1.145), duration of operation (OR = 1.011), preoperative serum albumin (OR = 0.689), postoperative anal- gesia (OR = 0.059), Logistic regression equation for predicting the risk of PPC was P(1) = 1/(1 + e- (- 9.803 + 1.776 x A + 0.135 x B + 0.011 x C - 0.372 x D - 2.835 x E)). Conclusion: Perioperative aerosol therapy, duration of postoperative antacids therapy, du- ration of operation, preoperative serum albumin and postoperative analgesia were independent risk factors associated with PPC in patients un- dergoing surgery for gallstone disease.
