title: The risk of pulmonary complication after surgery for gallstone disease.
abstract: OBJECTIVE
  To identify the risk factors of postoperative pulmonary complications (PPC) after surgery for gallstone disease.
  
  
  METHODS
  A total of 544 patients undergoing open surgery for gallstone disease were retrospectively 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 multivariate logistic analysis identified 5 independent risk factors associated with PPC, including perioperative 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 analgesia (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)].
  
  
  CONCLUSIONS
  Perioperative aerosol therapy, duration of postoperative antacids therapy, duration of operation, preoperative serum albumin and postoperative analgesia were independent risk factors associated with PPC in patients undergoing surgery for gallstone disease.
