ARISCAT, ASA and LAS VEGAS Risk Scores and the Incidence of Postoperative Pulmonary Complications in Thoracic Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

Single-lung ventilation: Patients undergoing thoracic surgery and intraoperative single-lung ventilation.

Study summary

Postoperative pulmonary complications (PPC) are among the main complications after the anesthetic-surgical procedure. It can be said that thoracic surgery results in impaired respiratory function in the postoperatively, due to the decrease in lung volumes and capacities (the vital capacity decreases by approximately 50-60% and functional residual capacity decreases by approximately 30% in the first 24 hours after surgery) diaphragm dysfunction, gas exchange impaired, cough and ineffective mucociliary clearance. Thus, our hypothesis is that the application of preoperative risk scores normally used for non-cardiac and non-thoracic surgeries may be effective on the predictability of the occurrence of CPP in patients undergoing ventilation single-lung. This is a prospective observational study in order to evaluate the performance of the ASA, ARISCAT and LAS VEGAS risk scores for predict the occurrence of postoperative pulmonary complications (PPC) in patients undergoing thoracic surgery with single-lung ventilation.
