very different patient groups, revealed a similar ED,, dose for pancuronium (62.2 and 64.4 pg/kg), but different ED,, values for vecuronium (56.2 and 36.1 pg/kg). Kong and Cooper chose to use the smaller dose, yet their patients received 60 pg/kg of vecuronium. Krieg et a1.l point out that a bolus dose of 36 pg/kg vecuronium produced a neuromuscular block of only 79% in their study, but this is increased by the prior use of suxamethonium. This accounts for the different values between the two reports. Cumulative log-dose response curves may also produce lower values for the ED,, dose when compared to the clinical use of a single bolus dose. In my practice a dose of 80 pg/kg vecuronium gives good, rapid intubation conditions, as suggested by Agoston et aL3 who found complete vocal cord relaxation in 9&100 seconds. Reversal of this dose after laparoscopy seems to cause no problem. The use of smaller doses of relaxant probably depends upon a prolonged period of mask ventilation with a volatile agent to achieve tracheal intubation which may not be advisable in some patient groups (i.e. day cases). Kong and Cooper reported a higher incidence of sore throat in the patients given vecuronium which may reflect the relatively small dose given. In comparison those given alcuronium (250 pg/kg) had a lower incidence of sore throat, but the most prolonged deficits in the measurements of postoperative muscle strength. This comparison may be unfair since the study referred to for the assessment of ED,, doses’ suggests a dose of only 140.8 pg/kg for alcuronium, nearly half of that used. However, the superiority of the newer muscle relaxants over alcuronium for short procedures such as laparoscopy must surely be intuitively correct.
