Abstract:
Objective To compare the efficacy of laryngeal mask airway-Advance (ALMA) and laryngeal mask airway-Supreme (S-LMA) in patients undergoing laparoscopic cholecystectomy.Methods Two hundred and forty ASA Ⅰ or Ⅱ patients,aged 18-64 yr,weighing 50-70 kg,undergoing laparoscopic cholecystectomy,were randomly divided into2 groups (n=120 each):group S-LMA (group S) and group A-LMA (group A).LMA was inserted after induction of general anesthesia with propofol 2.0-2.5 mg/kg,sufentanil 0.2 μg/kg and rocuronium 0.6 mg/kg.After LMA was placed,the rim was immediately inflated and positive pressure was applied to the reservoir bag of anesthesia machine circuit to check for leaks.The plateau pressure at which leaks occurred was recorded.BP,HR,SpO2,PErCO2 and Ppeak were monitored during operation.Fiberoptic bronchoscopy was performed and the placement was scored (0 =unable to see the vocal cords and the ventilation of the lungs was inadequate,4=vocal cords were clearly seen and ventilation was adequate).The rate of successful placement,placement time,the incidence of leaks during operation,duration of anesthesia and surgery,extubation time,emergence time,blood stain on the LMA after being removed,backflow after extubation and postoperatve complacations including sore throat,hoarseness and dysphagia were recorded.The efficacy for airway management and the difficulty of placement were scored.Results There was no significant difference in the rate of successful placement,difficulty of placement scores,blood stain on the LMA after being removed,incidence of backflow,sore throat,hoarseness and dysphogia,anesthesia time,duration of surgery,extubation time and emergence time between the two groups.The placement time was shorter in group S than in group A,but the airway sealing pressure,FOB scores and efficacy for airway management scores were significantly higher and the incidence of leaks during operation was significantly lower in group A than in group S.Conclusion Both A-LMA and S-LMA can provide adequate ventilation during laparoscopic cholecystectomy.The efficacy of A-LMA is better.
