A comparision of sevoflurane-remifentanil anaesthesia and propofol-remifentanil anaesthesia with laryngeal mask airway in burn surgery

Objective To compare the advantages and disadvantages of sevoflurane-remifentanil anaesthesia with propofol-remifentanil anaesthesia with laryngeal mask airway(LMA) in plastic surgery.Methods Thirty ASA classⅠ or Ⅱ,scheduled for general anesthesia for plastic surgery,were randomly divided into sevoflurane-remifentanil anaesthesia(group S,n=15) and propofol-remifentanil anaesthesia(group P,n=15).Anaesthesia was induced with a bolus of midazolam(0.05 mg/kg),remifentanil(1 μg/kg) and propofol(2.0 mg/kg),maintained with a combination of remifentanil(0.15 μg·kg-1·min-1) and sevoflurane(2%-3%) in group S or an infusion of propofol(6-8 mg·kg-1·h-1)in group P.MAP,HR and SpO2 were monitored and emergence time and complications were recorded.Results MAP and HR were all decreased after anesthesia induction compaered with those before in both groups(P0.05),which were recoverd to the baselines before skin incision in group S,but not in group P.Conclusion Under LMA ventilation,remifentanil combined with sevoflurane inhalation resulted in more stable hemodynamics and smooth anesthesia than propofol-remifentanil anaesthesia.
