Efficacy of Extended-release, Once Daily Tramadol for Post Operative Analgesia in Shoulder Arthroscopy

Efficacy of Extended-release, Once Daily Tramadol for Post Operative in Ambulatory Shoulder Arthroscopy

The investigators hypothesize that the use of tramadol will reduce pain and analgesic consumption after arthroscopic shoulder surgery.

The purpose of the study was to evaluate the efficacy of tramadol long acting for post operative pain in patients who had an arthroscopic shoulder surgery in ambulatory setting in comparison with a placebo. The intensity of pain was evaluated on a visual analog scale as the quantity of hydromorphone taken by patients, and the side effects during the first 72 hours.
