Postoperative Pulmonary Complications After Laparoscopic Surgery: Risk Factors and Predictive Scores

Area of Science:

• Anesthesiology
• Surgical Outcomes
• Pulmonary Medicine

Background:

• Laparoscopic surgery is linked to postoperative pulmonary complications (PPCs).
• PPCs can increase patient morbidity and hospital stay duration.
• Identifying risk factors for PPCs is crucial for improving patient outcomes.

Purpose of the Study:

• To identify risk factors for PPCs within 7 days of laparoscopic surgery.
• To evaluate the incidence of PPCs and associated complications.
• To assess the predictive performance of the Air Test for PPCs.

Main Methods:

• Prospective observational study of 250 patients undergoing laparoscopic surgery.
• PPCs defined per European Society of Anaesthesiology and Intensive Care Medicine guidelines.
• Logistic regression analysis used to identify independent risk factors for PPCs.

Main Results:

• PPCs occurred in 14.4% of patients.
• Independent risk factors for PPCs included age over 60 and a positive Air Test.
• The Air Test showed modest accuracy (AUC 0.66) in predicting PPCs.

Conclusions:

• The incidence of PPCs following laparoscopic surgery is 14.4%.
• Advanced age and a positive postoperative Air Test are significant risk factors for PPCs.
• The Air Test has limited accuracy in predicting PPCs but warrants further investigation.
