ABSTRACT
Objective To investigate the pharmacodynamics of cis-atracurium after a single bolus injection in adults and children undergoing live donor liver transplantation during preanhepatic,anhepatic and neohepatic phase.Methods Twenty-six ASA Ⅲ or Ⅳ patients aged 7 months-64 yr,werghing 6-80 kg of beth sexes undergoing live donor liver transplantation were assigned to one of 2 groupsgroup A adults (n=16) and group B children(n=10).Anesthesia was induced with midazolam 0.05 mg/kg and fentanyl 3-5 μg/kg in both groups and propofol TCI (Cp 3μg/ml) in adults.As soon as the patients lost consciousness,tracheal intubation was facilitated with 2×ES95 of cis-atracurium (0.1 mg/kg).The intubation condition wag recorded.The response of the adductor pollicis to TOF stimulation of the ulnar nerve was recorded (TOF-Guard).An increment of cis-atracurium 0.03 mg/kg was given when T1 returned to 25% of baseline value or the four twitches appeared.Cis-atracurium administration and sevoflurane inhalation were stopped before the three phases and resumed when T1 reached 75% of baseline value.The onset time,mterval between the 2 cis-atracurium administrations,duration of clinical action and recovery of neuromuscular block were recorded.The intubation condition was evaluated.Results The onset time was significantly shorter in adults than in children.There was no significant difference in intubation condition between the 2 groups.The interval between the 2 cis-atracurium administrations and duration of clinical action were similar during the 3 phases in adults and significantly shorter during neohepatic phase than during anhepatic phase in children.The recovery was faster in children than in adults.Conclusion Cis-atracurium 2×ED95 (0.1 mg/kg)can be used for both adults and children undergoing live donor liver transplantation.The onset time is longer and recovery is faster in children than in adults.Cis-atracurium is suitable for patients of different ages and liver function.
