Could a simple inhaled drug during surgery prevent dangerous lung complications?

This study looked at whether giving lidocaine as a mist into the lungs during major abdominal surgery could lower the chance of serious lung problems after the operation. Lung complications after surgery can lengthen hospital stays and increase costs and death risk. The study included 270 adults having planned major non-cardiac surgery under general anesthesia. The key approach was to use lidocaine's anti-inflammatory effects to protect the lungs.
