Time-course effect of rocuronium in patients with obstructive jaundice / 第二军医大学学报

ABSTRACT

Objective:To study the time-course effect and postoperative residual curarization of rocuronium(ROC) in patients with obstructive jaundice.Methods: Forty patients(with normal renal function and without muscle or nerves diseases) receiving elective surgery under general anesthesia were divided into 2 groups trial group(group Ⅰ) included 20 ASA(American Society of Anesthesiologists) Ⅲ patients with obstructive jaundice and control group(groupⅡ) included 20 ASA Ⅰ-Ⅱpatients without obstructive jaundice.All patients received total intravenous anesthesia with pentothal sodium,fentainyl and propofol.Neuromuscular blockade was evaluated with train-of-four(TOF) stimuli of the ulnsar nerve during operation.The 3?ED_(95)((0.9 mg/kg)) of ROC was given during anesthesia induction.As TOF rate(TOFR) reached 25%,1?ED_(95)(0.3 mg/kg)of ROC was added.Postoperation neuromuscular blockade was continuously evaluated until TOFR reached 90%.Tracheal extubation trigger was defined as that patient was able to open his/her eyes and to raise his/her arm or head for 5 s.The onset time,effect time of ROC,the time of TOFR from 0 to 70% and from 70% to 90%,and the TOFR at the time of tracheal extubation were observed.The blood gas analysis was done at the same time.Results: The effect duration in groupⅠwas longer than that in group Ⅱ(P
