Abstract
Background
Postoperative pulmonary complications are important problems that prolong the length of the hospital stay and increase patient mortality. However, our knowledge of the postoperative factors that increase the risk of these complications is less than complete.
Methods
We conducted a prospective study to determine the risk factors for postoperative pulmonary complications. A total of 199 patients were referred to the Pulmonology Department for preoperative pulmonary evaluation. We reviewed the perioperative variables according to the National Surgical Quality Improvement Program (NSQIP). Postoperatively, we collected data on the occurrence of postoperative pulmonary complications and we evaluated the relationship between the perioperative variables and outcomes.
Results
Twenty two patients (11%) had pulmonary complications; 6 had respiratory failure, 4 had pneumonia, 13 had pleural effusion and, 2 had atelectasis. Five variables were statistically significantly associated with pulmonary complications on the bivariate analyses. Multiple logistic regression analyses revealed that three of these variables were independently associated with an increased risk of pulmonary complications; a high cardiac risk index (OR 16.5, p=0.002), emergency surgery (OR 10.3, p=0.017), and thoracic/abdominal surgery (OR 3.8, p=0.047).
