The short elimination half-life of vecuronium suggests it may be delivered more efficiently by continuous infusion than by traditional bolus injections. The objective of this study was to compare manual administration with computer-controlled administration. Anesthesia was induced in 22 patients (American Society of Anesthesiologists [ASA] physical status I and II) with fentanyl and sodium thiopental and maintained with halothane and nitrous oxide in oxygen. Neuromuscular function was assessed at the hypothenar eminence and the adductor pollicis (train-of-four stimulation). A bolus of 0.1 mg/kg of vecuronium was given to obtain 100% twitch depression for tracheal intubation. After twitch height returned to 25% of control, relaxation was maintained by traditional bolus injections (group 1, n = 7), manually controlled continuous infusion (group 2, n = 7), or computer-controlled continuous infusion (group 3, n = 8). In all three groups the desired level of relaxation was 90% twitch depression. Variability of relaxation differed significantly among the three groups (group 1: 10.5%, group 2: 12.4%, group 3: 7.1%). Twitch height was more constant with computer control than with either bolus injections or manual infusion (P less than 0.05). There was no statistically significant difference in the drug requirement (group 1: 1.60 microgram/kg/min, group 2: 1.51 microgram/kg/min, group 3: 1.45 microgram/kg/min). Variability in the mechanomyogram (n = 12) was much higher than in the electromyogram (n = 10). Computer-controlled infusion may be a useful adjunct for the anesthesiologist who desires a stable level of patient relaxation when using short-acting, non-depolarizing relaxants.
