| Objective To observe the neuromuscular blockade effects and side effects of cisatracurium on rapid endotracheal intubation.Methods Sixty patients were randomized to three groups(n=20):A group(cisatracurium, 2min),B group(cisatracurium,3min),C group(cisatracurium,4min).All patients were anesthetized with intravenously injection of midazolam(0.05mg·kg-1),fentanyl(2μg·kg-1),etomidate(0.3mg·kg-1) and cisatracurium(0.15mg·kg-1).Then the haemodynamical changes before and 1~15min after administration of the relaxant were recorded,the neuromuscular blockade and side effects of groups were also observed.Results The intubation situationof B,C groups was better than A group.The B,C groups had no significant differences(P>0.05).The haemodynamical changes had no significant differences(P>0.05).But the Bp and HR after lmin of intubation were higher than ante-intubation within group.The side effects had no significant differences in 3 groups (P>0.05).Conclusion The intubation situation can achieve best at 3min after administration of the cisatracurium(0.15mg·kg-1).Cisatracurium does not affect plasma histamine concentration and haemodynamics.It can be safely used in the rapid endotracheal intubation of general anesthesia with satisfactory neuromuscular blocking effects. |
