[Evaluation of the analgesic effectiveness of tramadol hydrochloride in surgical practice]

Tramadol hydrochloride was administered to: a) 90 patients who underwent various abdominal surgery (group A) immediately after operation; b) 50 patients with inoperable tumors of pharynx, stomach, pancreas, liver and biliary tract and colon (group B); c) 32 patients in surgical out-patient clinic (group C). Excellent and favourable results (group A - 87.8%; group B - 74%, and group C - 75%) and negligible adverse reactions advocate the use of tramadol hydrochloride both in in- and out-patient surgical clinics as an effective analgesic agent.
