Risk factor analysis of postoperative complications in patients with emergency general surgery / 临床麻醉学杂志

ABSTRACT

Objective To investigate the relationship between the occurrence of adverse events during operation and postoperative complications in emergency general surgery patients, and to analyze the risk factors of postoperative complications.Methods We retrospectively analyzed 689 e-mergency general patients undergoing general anesthesia emergency surgery during the period of Sep 1,2015 to Sep 1,2016 in the First Affiliated Hospital of Nanjing Medical University.The clinical fac-tors that may influence the outcomes and postoperative complications were collected and analyzed using univariate analysis and multivariate Logistic regression analysis.Results Among the 689 patients enrolled in the study,there were 165 (23.9%)patients who had major complications within 30 days after surgery.The most common postoperative complications were respiratory complications (40.6%).The inde-pendent risk factors of postoperative complications including age (OR 1.880,95%C I 1.448-2.440),ASA classification (OR 3.303,95%C I 2.303-4.736),intraoperative hypotension duration more than 20 minutes (OR 2.501,95%C I 1.387-4.510),intraoperative rapid arrhythmia (OR 2.173,95% C I 1.002-4.711) and surgical level (OR 1.814,95% C I 1.060-3.103).Conclusion Emergency general surgery in patients with intraoperative hypotension duration more than 20 minutes and the occurrence of rapid arrhythmia are independent risk factors for postoperative complications.During the circulation man-agement of emergency surgical patients,the reduction of systolic blood pressure in the operation should be controlled within 20% of the base value to reduce the risk of postoperative complications.
