Summary

This study tested a way to keep people asleep during lung surgery without using strong opioid painkillers. Instead, they used a drug called esketamine along with standard anesthetics. The goal was to see if this approach could help patients breathe better during the operation. The study involved 84 adults having lung nodule surgery, and compared the opioid-free method to a standard opioid-based approach.
