What this Trial Is About
Postoperative pulmonary complications (PPC) are common after surgery and can prolong hospital stays and increase healthcare costs. Thoracic surgery often impairs respiratory function due to reduced lung volumes, diaphragm dysfunction, and impaired gas exchange. This research aims to evaluate how well preoperative risk scores—ASA, ARISCAT, and LAS VEGAS—predict PPC in patients undergoing thoracic surgery with single-lung ventilation. The study observes patients undergoing thoracic surgery who receive intraoperative single-lung ventilation. It is a prospective observational study collecting data at two hospitals using standardized forms. The anesthesiology teams will evaluate patients before, during, and after surgery. Participants will be monitored until hospital discharge or for up to 30 days after surgery. Participants will be closely observed and data recorded on their respiratory status and any complications. Researchers will analyze how accurately the risk scores predict the occurrence of PPC. The primary outcome is the rate of postoperative pulmonary complications within 30 days. This monitoring helps understand patient risks and improve care after thoracic surgery.
