[The evaluation of the efficacy and safety of using nalbuphine hydrochloride (Nubain) in patients in the early postoperative period].

Nubaine (N) was used in 92 patients operated on the lungs, heart and major vessels, abdominal organs. N at a dose of 0.3 mg/kg caused adequate analgesia in 62-85% of cases on days 1-3 after surgery; it is an effective analgesic among those used in patients with acute postoperative pain. The effect of N on circulation, respiration, gas exchange, metabolism, and hormonal status was studied. It has been shown that N is a safe agent which has no considerable effect on respiration, hemodynamics, blood gas composition, and metabolism. In patients at high risk analgesia with N caused no serious side effects.
