Laryngeal mask airway-composites remifentanil and sevoflurane or propofol anesthesia in the perioperation of the transurethral resection of the prostate

Objective To compare the advantages and disadvantages of sevoflurane-remifentanil anaesthesia with propofol-remifentanil anaesthesia with laryngeal mask airway(LMA) in the perioperation of the transurethral resection of the prostate.MethodsForty patients,classified from ASA Ⅰ to III grade and scheduled for general anesthesia for the perioperation of the transurethral resection of the prostate,were randomly divided into sevoflurane-remifentanil anaesthesia group(group S,n=20) and propofol-remifentanil anaesthesia group(group P,n=20).Anaesthesia was induced with a bolus of midazolam(0.03~0.06 mg·kg-1),fentynal(3 μg·kg-1),atracurion(0.5 mg·kg-1)and sevoflurane(0.5%~3%) in group S or an infusion of propofol(0.5～1 mg·kg-1) in group P.Laryngeal mask airway(LMA) was used for airway maintenance after inducing of anaesthesia.Anesthesia was maintained through pumping remifentanil(0.15 μg·kg-1·min-1).At the same time,group S were given sevoflurane(0.5%~3%)and group P were given infusion of propofol(3～8 mg·kg-1·h-1).Heart rate was monitored and emergence time and complications were recorded.ResultsMAP and Heart rate were all decreased after anesthesia induction compared with those of before in both groups(P0.05),which recovered to the base lines before skin incision in group S,but not in group P.ConclusionUnder LMA ventilation,remifentanil combined with sevoflurane inhalation results in more stable hemodynamics and smoother anesthesia than propofol-remifentanil anaesthesia.
