ABSTRACT
Objective To compare the pharmacodynamics of rocuronium intermittently administered according to body surface area and real body weight and individual differences. Method Forty-two patients undergoing elective surgery under general anesthesia were enrolled into the body surface area group (BSA group) and the real body weight group (RBW group), with 21 patients in each group. The patients in the two groups were induced with 2ED95 of rocuronium according to body surface area and real body weight (16.64 mg/m2 in BSA group; 0.6 mg/kg in RBW group). Whenever T1 recovered to 10%, a dosage of 0.5ED95 was administred repeatedly for 30 min before the end of the operation. The time of neuromuscular blockade and recovery of muscle relaxation were recorded, and the dosage of rocuronium was also recorded. Results No significant difference in each index of neuromuscular block time-effect was found between the two groups (P > 0.05). The single dosage and maintainance amount of muscle relaxation were less in the BSA group than that in RBW group (P < 0.05). Compared with the RBW group, the single dosage, dosing intervals, pharmacological duration and the time TOFr recovered to 0.7 between the different individuals were less in the BSA group (P < 0.05). Conclusion The intermittent administration of rocuronium can maintain the same clinical efficacy according to body surface area as that according to real body weight , with significantly less dosageand reducing the differences of individuals in blockade time-effect of muscle relaxation.
