The Relation between the Response to “Train-of-four” Stimulation and Receptor Occlusion during Competitive Neuromuscular Block

The responses to a train of four indirect stimuli at 0.5-second intervals were examined in the cat and the dog during recovery from neuromuscular block produced by d-tubocurarine. The relation of the twitch responses during the train to the fractional receptor occlusion by the competitive neuromuscu
