Atracurium and alcuronium have been compared during halothane anaesthesia, by measurement of the mechanical response of the adductor pollicis muscles to train-of-four stimulation and by clinical observation. Atracurium appeared significantly shorter-acting than alcuronium. However, results suggested that the action of alcuronium may not be of "medium duration ". A comparison of three indices of muscle twitch response to the train-of-four nerve stimulation, seemed to indicate that the D'/D ratio gave the best overall index of neuromuscular blockade in this study.
