Abstract:
Objective To investigate the neuromuscular blocking effects and clinical pharmacology of different dosage of mivacurium chloride in infants during sevoflurane anesthesia. Methods Forty ASA I infants undergoing sevoflurane general anesthesia were randomly assigned to tow groups according to the dose level of mivacurium: group1: 200 μg/kg ( n =20) and group2: 250 μg/kg ( n =20) . TOFs were determined synchronously. The onset time of mivacurium, recovery time of spontaneous breathing and cardiovascular reactions were measured. Results The onset time was significantly shortened in group 2 compared with group 1 (P<0.05) . There was no significant difference in the recovery time of spontaneous breathing between the two groups. 2 minutes after mivacurium was injected, DBP in group 2 decreased significantly compared with baseline and group 1. 3 minutes after mivacurium was injected,SBP in group 2 decreased significantly compared with baseline and group 1. Conclusion In infants undergoing sevoflurane general anesthesia, the onset time of mivacurium can be shortened when 250μg/kg was administered,but the depression of cardiovascular system may occurr simultaneously.
