ABSTRACT
An open prospective and longitudinal study was carried out including 102 female patients whose pain was due to gyneco-obstetric surgery. The average age was 31.5 years and the average weight was 67 kg. The tramadol hydrochloride was administered as a single 100 mg dose p.o. or i.m., when moderate to intense pain was present. At the beginning of the trial, 96.1% of the patients presented moderate to very intense pain. At the end of the period of the trial, 74% reported none or mild pain. The analgesia began after an average of 17 minutes i.m. and 28 minutes p.o. The identified adverse effects were: nausea 1%, vomiting 5% and somnolence 8%. In accordance with the obtained results, we conclude that tramadol chlorhydrate is a good alternative for the treatment of moderate-to-severe acute pain of obstetric and gynecological origin.
