Middle lobe syndrome

This trial is testing whether using a lower or higher flow of fresh gas during general anesthesia affects how well the lungs recover after laparoscopic gallbladder removal. About 120 adults having this surgery will be randomly assigned to receive either low-flow (0.5 L/min) or hi…

This study tests whether using a high-flow nasal cannula (a device that delivers warm, moist oxygen at high speeds) for 24 hours after major abdominal surgery can prevent lung complications like pneumonia or collapsed lungs. Researchers will compare this to standard oxygen therap…

This study looks at whether changing body position and doing special breathing exercises can help prevent lung issues like pneumonia after heart surgery. About 124 adults having planned heart surgery will be split into four groups: one getting usual care, one doing only breathing…

This study will use lung ultrasound to check how different surgical positions (lying on back, stomach, side, or in lithotomy) affect lung collapse after general anesthesia. Researchers will enroll 100 adults having planned surgery. The goal is to see if some positions are better …

This study looks at whether placing patients face-down (prone) soon after heart surgery can improve how well the right side of the heart works. The idea is that this position helps open up collapsed parts of the lungs, making it easier for the heart to pump blood. About 80 adults…

This study will test whether using higher or standard pressure on a ventilator during surgery helps patients breathe better after waking up. About 360 adults having planned non-chest, non-heart surgery will be randomly assigned to one of two pressure levels. The main goal is to s…

This study looks at whether a bedside lung ultrasound can help doctors see how well the lungs of obese patients are opening during a breathing machine procedure. The goal is to find the best air pressure to keep lungs open and improve oxygen levels. About 45 adults with a BMI of …

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, …

This study will compare two ways of helping children breathe during surgery—Volume-Controlled Ventilation and Pressure-Regulated Volume Control—to see which one causes less lung collapse. About 88 children will be monitored using lung ultrasound and electrical imaging. The goal i…
