About the study
This is a prospective, randomized study of ketamine versus no ketamine in approximately 100 patients undergoing hemorrhoidectomy for Grade III or IV hemorrhoids. The participants will be blinded to which treatment arm they are assigned, because participants will be under anesthesia when the ketamine is administered. The investigators will know whether the participant receives ketamine or not.
