Randomized Controlled Trial Comparative Study Clinical Trial
Metoclopramide and prochlorperazine do not decrease propofol hypnotic requirements.
One hundred patients scheduled for minor surgery were given either saline, metoclopramide 0.1 mg.kg-1 or 0.2 mg.kg-1, or prochlorperazine 0.1 mg.kg-1 or 0.2 mg.kg-1 before induction of anaesthesia with a fixed rate infusion of propofol. Neither metoclopramide nor prochlorperazine reduced the induction dose of propofol. The possibility that these agents increased the induction dose could not be excluded.

Randomized Controlled Trial Clinical Trial
The influence of isoflurane on a continuous infusion of mivacurium.
Sixty surgical patients were studied to evaluate the neuromuscular effects of mivacurium 0.15 mg.kg-1 (2 x ED95) for tracheal intubation. After intubation the patients were randomly allocated to receive alfentanil with either propofol (starting with 9 mg.kg-1 h-1, reducing to 6 mg.kg-1 h-1 after 20 min) or isoflurane (0.5% end-tidal). In addition, all the patients were given a continuous infusion of mivacurium 10 micrograms.kg-1 min-1 after tracheal intubation which was adjusted to maintain 90% depression of T1. ⋯ Tracheal intubation was completed 232 (155) s after administration of the relaxant and intubating conditions were graded as 'excellent' or 'good' in 56 patients. Although the mean (SD) mivacurium infusion rate for maintaining T1 at 10% was higher in the propofol group, 4.8 (2.1) compared with 4.4 (2.0) micrograms.kg-1 min-1 in the isoflurane group, this was not significantly different (p > 0.05). The mean (SD) recovery index was prolonged in the isoflurane patients, 757 (508)s, compared to those receiving propofol, 466 (219)s (p < 0.05).
