Summary

This study looks at whether smelling coffee can help patients feel less pain and recover faster after laparoscopic gallbladder removal. About 66 adults who have never had surgery before will be randomly assigned to smell coffee or not after their operation. Researchers will measure pain levels and how quickly patients are ready to leave the recovery room.
