Randomized Controlled Trial Clinical Trial
Reversal of epidural morphine-induced respiratory depression and pruritus with nalbuphine.
The effect of nalbuphine on the respiratory depression, pruritus and analgesia induced by epidural morphine was determined in a randomized, prospective, double-blind, placebo-controlled fashion. Twenty ASA physical status I women received 0.1 mg.kg-1 epidural morphine at induction of general anaesthesia for elective total abdominal hysterectomy. Group 1 (n = 14) received 0.3 mg.kg-1 nalbuphine intravenously six hours after the epidural morphine administration. ⋯ Nine of the 14 patients receiving nalbuphine appeared to become more sedated, despite an improvement in ventilation. Pruritus was antagonized by 0.1 mg.kg-1 nalbuphine (p less than 0.006). There was no reversal of analgesia after administration of 0.3 mg.kg-1 nalbuphine.

We report the case of a 38-year-old eclamptic patient undergoing emergency Caesarean section who required awake nasotracheal intubation because of her massively swollen and lacerated tongue. Vasoconstriction, in addition to topical anaesthesia, was required due to thrombocytopaenia. The use of three per cent lidocaine with 0.125 per cent phenylephrine for anaesthesia and vasoconstriction is described with successful maternal and neonatal outcome.
