Abstract

OBJECTIVE

To investigate the impact of cuff pressure on airway leak pressure in laryngeal mask airway(LMA)Supreme and Flexible.

METHODS

Patients about to have elective breast surgery were divided into Supreme group(35 cases)and Flexible group(33 cases). After general induction of anesthesia,LMA Supreme or Flexible was inserted by one anesthesiologist. We confirmed the LMA location,adjusted the cuff pressure,and recorded the peak airway leak pressures under different cuff pressures(10,20,30,40,and 50 cmH2O).

RESULTS

In Supreme group,peak airway leak pressures [(24.46±5.43),(25.11±5.51),(25.86±5.57),(26.17±5.72)cmH2O] under 20,30,40,and 50 cmH2O cuff pressure showed no significant difference(P>0.05)between each other,but significantly higher than that under 10 cmH2O cuff pressure(20.80±4.63)cmH2O(P<0.05). And in the Flexible group,peak airway leak pressures [(20.09±2.98),(20.70±3.08),(21.21±3.15)cmH2O] under 30,40,50 cmH2O cuff pressure also showed no significant difference(P>0.05)between each other,but significantly higher than those under 10 or 20 cmH2O cuff pressure [(17.52±2.39),(18.61±2.42)cmH2O]. Mean peak airway leak pressure [(25.40±5.52) cmH2O] of LMA Supreme was significantly higher than that of LMA Flexible(20.67±3.06)cmH2O(P<0.05).

CONCLUSIONS

Mean airway leak pressure of LMA Supreme is higher than LMA Flexible. The lowest cuff pressure to meet the tightness requirement with LMA Supreme is 20 cmH2O,which is lower than Flexible(30 cmH2O).

摘要

目的

探讨套囊压力对喉罩Supreme和Flexible气道漏气压力的影响。

方法

将择期行乳腺手术的患者分为Supreme组（35例）和Flexible组（33例）。全身麻醉诱导后，由一名麻醉医生插入喉罩Supreme或Flexible。确认喉罩位置，调整套囊压力，并记录不同套囊压力（10、20、30、40和50 cmH₂O）下的气道漏气峰值压力。

结果

Supreme组中，20、30、40和50 cmH₂O套囊压力下的气道漏气峰值压力[（24.46±5.43）、（25.11±5.51）、（25.86±5.57）、（26.17±5.72）cmH₂O]相互之间差异无统计学意义（P>0.05），但显著高于10 cmH₂O套囊压力下的（20.80±4.63）cmH₂O（P<0.05）。在Flexible组中，30、40、50 cmH₂O套囊压力下的气道漏气峰值压力[（20.09±2.98）、（20.70±3.08）、（21.21±3.15）cmH₂O]相互之间差异也无统计学意义（P>0.05），但显著高于10或20 cmH₂O套囊压力下的[（17.52±2.39）、（18.61±2.42）cmH₂O]。喉罩Supreme的平均气道漏气峰值压力[（25.40±5.52）cmH₂O]显著高于喉罩Flexible的（20.67±3.06）cmH₂O（P<0.05）。
