Postoperative pulmonary complications

This trial tests whether a newer ventilation method, called flow-controlled ventilation, keeps the lungs and diaphragm in better shape than the standard pressure-controlled method during elective heart bypass surgery. About 154 adults scheduled for on-pump coronary artery bypass …

This trial tests whether using 50% oxygen instead of 100% oxygen during one-lung ventilation reduces collapse (atelectasis) in the non-operated lung after thoracoscopic right lung lobectomy. One hundred adults undergoing elective surgery will be randomly assigned to receive eithe…

This study tests a new method for setting ventilators during abdominal surgery to prevent postoperative respiratory failure. The approach adjusts settings based on 'mechanical power,' a measure that combines several ventilator parameters. The trial will enroll 490 adults having a…

This study tests whether giving the numbing drug lidocaine during heart surgery can reduce lung damage in infants. 320 babies under 1 year old having heart surgery will receive either lidocaine or a placebo. The goal is to see if lidocaine lowers the severity of lung injury after…

This study tests whether a special breathing technique called a recruitment maneuver can prevent lung collapse (atelectasis) in children aged 1-14 during surgery. 78 children will be randomly assigned to one of three groups: standard breathing support, a recruitment maneuver, or …

This international trial investigates whether the way a patient's airway is managed during general anesthesia affects the risk of lung complications after surgery. Researchers randomly assign about 6,800 adults having elective non-cardiac surgery to different combinations of brea…

This trial tests whether a one-minute suction of the airway leading to the surgical lung helps it collapse faster and more completely during uniportal video-assisted thoracoscopic surgery (U-VATS). Good lung collapse gives the surgeon a clearer view and may reduce complications. …

This study investigates whether high-flow nasal cannula (HFNC) oxygen therapy can reduce lung collapse (atelectasis) after laparoscopic surgery. About 90 adults undergoing elective laparoscopic procedures will receive either HFNC or standard oxygen after breathing tube removal. D…

This study will observe 110 adults having planned heart bypass surgery. Researchers will record settings on the breathing machine during surgery and check if patients develop lung complications like pneumonia or need a breathing tube for too long. No new treatments are given—the …

This study looks at three different ways to set the breathing machine during robotic surgery to find which one best protects the lungs and helps patients breathe better after surgery. About 120 adults having elective robotic surgery will take part. The goal is to see if adjusting…

This study watches how the breathing machine's settings during laparoscopic belly surgery may affect lung problems after surgery. Researchers will record machine data during surgery for 90 adults and check for complications like low oxygen or needing breathing help. No changes ar…

This study tests whether a special teaching method called '5T Teach-Back' helps patients learn breathing exercises and use a spirometer (a device that measures how well you breathe) before abdominal surgery. The goal is to see if this method improves patients' knowledge, skills, …
