Comparative StudyA comparison of edrophonium and neostigmine for the antagonism of atracurium-induced neuromuscular block.
Edrophonium, 0.5 mg/kg, or neostigmine, 0.05 mg/kg, was administered to groups of 20 patients each, for antagonism of atracurium-induced block at varying degrees of spontaneous recovery. Neuromuscular block was studied using train-of-four (TOF) stimulation. ⋯ Five of the seven patients in the edrophonium group who failed to be reversed adequately had shown three or fewer twitches to a TOF stimulation. It is concluded that edrophonium in a dose of 0.5 mg/kg does not consistently antagonize neuromuscular blockade induced by atracurium, particularly if all four responses to a TOF stimulation are not elicited prior to antagonism of the block.
