Zap your wrist, need less drugs? study tests pain relief during surgery

This study tested if a non-invasive electrical stimulation device, worn on the wrist and ankle, could help patients need less strong pain medication during a specific part of surgery. Researchers enrolled 60 adults undergoing general anesthesia to see if the stimulation made the standard drug more effective at preventing heart rate and blood pressure spikes when the breathing tube was inserted. The goal was to see if this method could be a safe, needle-free option for managing surgical pain.
