Abstract:
ObjectiveTo compare the efficacy of laryngeal tube-suction airway (LTSA) and SLIPA laryngeal mask airway (SLIPA) in obese patients undergoing laparoscopic cholecystectomy.MethodsSixty ASA Ⅰ or Ⅱ patients,aged 40-60 yr,with body mass index ＞ 30 kg/m2,undergoing laparoscopic cholecystectomy,were randomly into 2 groups ( n =30 each):group LTSA ( group Ⅰ ) and group SLI PA ( group Ⅱ ).Anesthesia was induced with target-controlled infusion (TCI) of propofol with the target plasma concentration (Cp) of 3-5 μg/ml and remifentanil (target Cp =4-6 ng/ml ).Rocuronium 0.6 mg/kg was injected intravenously as soon as the patients lost consciousness.LTSA and PLMA were inserted when BIS value was 50-60.HR,mean arterial pressure (MAP),SpO2,peak airway pressure(Ppeak) and PETCO2 were monitored during operation.Fiberoptic bronchoscopy was performed and the placement was scored.The placement time,the rate of successful placement at first attempt,airway sealing pressure,the failure of airway management and side effects were recorded.ResultsThere was no significant difference in HR,MAP,the fiberoptic bronchoscopy scores,the airway sealing pressure,and the incidence of side effects between the two groups.The placement time was significantly shorter in group Ⅰ than in group Ⅱ (P ＜ 0.05).The rate of successful placement at first attempt was more than 90％ and no failure was found in airway management in both groups.The SpO2,Ppeak,and PET CO2 were within the normal range during operation in both groups.ConclusionBoth LTSA and SLIPA can be safely and effectively used in obese patients undergoing laparoscopic cholecystectomy,however,LTSA placement is more easier.
