Clinical experiences with naloxone in neuroradiology.
In 17 patients, the reversal by naloxone of a short duration narcotic anesthesia done for neuroradiology, was studied. Neuroleptanalgesic technique comprised d-hydrobenzperidol (5-10 mg) and fentanyl (+/- 0.4 mg) after barbiturate induction, and curarization with pancuronium, reversed by neostigmine. In group A 2 microgram/kg naloxone I.V. was given and 1 microgram/kg I.M. 30 min. later and in group B 1 micrometer/kg I.V. and 30 min. later 0.5 micrometer/kg. Reversal of narcotic depression was good and well maintained for 60 min. in both groups, as evidenced by respiratory rate, respiratory minute volume, pHa, PaCO2. Marginal temporarily cardiovascular stimulation occurred with arousal. Tolerance was good. It is concluded that antagonisation of respiratory depression due to narcotic anesthesia is possible with small titrated dosis of naloxone.
