[The effect of nalbuphine hydrochloride (Nubain) on respiration in surgical patients]

The effect of nalbufin hydrochloride (Nubain) on breathing was studied in 28 patients after abdominal operations. It was shown that, regardless of its partial effect on the mu-receptors, Nubain caused no respiratory disturbances. The authors recommend it for analgesia in abdominal operations, but only after careful evaluation of the general status and the respiratory function in the operated patient.
