Abstract:
Objective To evaluate the efficacy and safety of China-made remifentanil in a randomized, controlled and double-blinded multi-center clinical study. Methods Two hundred and one patients were randomly divided into two groups: control group received intravenous fentanyl and study group received intravenous remifentanil. In both groups anesthesia was induced with propofol 1-2 mg ?kg-1 and fentanyl 2.5?g/kg or remifentanil 2 ?g/kg. Intubation was facilitated with succinylcholine 1.0-1.5 mg?kg-1. The patients were mechanically ventilated(VT 8-10 ml?kg-1 , RR 10 bpm) . Anesthesia was maintained with fentanyl at 0.03 ?g?kg-1?min-1 or 0.2?g?kg-1?min-1 supplemented with 66% N2O and intermittent iv boluses of vecuronium. The efficacy variables recorded were the changes in blood pressure(BP) and heart rate(HR) during surgical stimulation and the quality of anesthesia. The safety variables included BP and HR, the doses of ephedrine, atropine, urapidil and naloxone required during surgery, the volume of intraoperative blood loss, changes in EGG, and the pre- and post-operative liver and kidney function, extubation time, emergence time (opening eyes when the patient's name is being called), end-tidal CO2 before extubation, admission to PACU or ICU, and the unexpected events in postoperative period. Results The anesthetic efficacy of remifentanil was similar to that of fentanyl with better analgesic effect . Remifentanil wore off faster in comparable doses. Conclusion China-made remifentanil is a good and safe anesthetic with better analgesic effect.
