Abstract:
Until recently edrophonium has not been used in clinical anesthesis because of its short duration of action and poor anticholinesterase activity. However there has been a renewed interest in the use of edrophonium for the reversal of the new intermediate acting relaxants, vecuronium and atracurium, which have a fast spontaneous recovery rate. Edrophonim in sufficient dosages may produce a fast onset of antagonism of non-depolarizing neuromuscular blockade with minimal muscarinic side effects. The porpose of this study was therefore to compare the efficiency of edrophonium and neostigmine in reversal of a profound neuromuscular blockad following continuous infusion of vecuronium (0.06 mg/kg/hr). Recovery of T1 and T4 twitch height, change of heart rate and mean arterial pressure were obsered after antagonism with control mixture group (n=10): neostigmine 0.04mg/kg and atropin 0.02 mg/kg, and experimental mixture group (n=9): edrophoninm 0.5mg/kg and atropine 0.007 mg/kg were evaluated respectively at the 10% spontaneous recovery of T1 twitch height. Recovery of T1 was more faster in the edrophonium group than in the neostigmine group but it was significant until 5 minutes after antagonism (p<0.05) and recovery of T4 was also significantly faster in the edrophonium group until 5 minutes after antagonism but thereafter, conversly faster in the neostigmine group than in the edrophonium(p<0.05). Changes of heart rate with +/-5% after edrophonium administration were observed. We conclude that edrophonium provides a more rapid antagonism within 5 minutes after antagonizing vecuronium infusion, and small change in heart rate, but no other any advantage in using edrophomine instead of neostigmine for reversal after 5 minutes.
