ABSTRACT
Objective To investigate the pharmacodynamics characteristics of continuously infused cisatracurium besylate during total intravenous anesthesia. Methods Sixty ASA Ⅰ - Ⅱ patients undergoing elective oromaxillo-facial region surgeon were randomly divided into 4 groups. 1.0, 2.0, 3.0 μg/ (kg · min ) of cisatracurium besylate was continuously infused differently in group Ⅰ, group Ⅱ and group Ⅲ, and 0.1 mg/kg of cisatracurinm besylate was injured interruptedly into group Ⅳ after anesthesia induction. Neuromuscular function was assessed using an accelerometer with train-of-four (TOF) stimulation, the maximum depression of T1and times to T1 recovered to 25%(the clinic time), 75%, 90%(the vivo time) were noted. The recovery index (time of T1 recovery from 25% to 75%) was also calculated. Results The drug consumptions of cisatracurium besylate in group Ⅰ and group Ⅱ were diminished than those in group Ⅲ and group Ⅳ [(59.1±9.6),(116.7±11.5)μg/kg vs (174.9±23.1), (177.2±20.4) μg/kg](P<0.01), and group Ⅲ and group Ⅳ were nearly (P>0.05 ). The maximum depression of T1, the clinic time and the vivo time in group Ⅰ, Ⅱ,Ⅲ were smaller than those in group Ⅳ [ ( 18.5±3.6)%, (6.4±2.7)%, 0 vs (25.0±0.0)% ] (P < 0.01 ), but there were. No significant differences in recovery index in 4 groups. The maximum depression was diminished (P< 0.01 ) and the clinic time and the vivo time were prolonged (P<0.05) with the inerease of the dosage of cisatracurium besylate in group Ⅰ, Ⅱ, Ⅲ. Conclusions With no cumulative effect, the duration of recovery of muscle relaxation is shortened and the recovery index of continuously infused eisatracurium besylate is prolonged. It indicates that the cisatracurium besylate is suitable for the continuously infusion for surgeon patients.
