简要总结
The difference of oropharyngeal leak pressure and sealing pressure between new supraglottic airway devices.
详细描述
In this clinical study, investigators want to discuss the issue that oropharyngeal leak pressure and sealing condition with different SGA including air-Q、i-gel、LMA-supreme、AMBU auragain 、ProSeal LMA and other new SGAs.
In the perioperative period, investigators documented respiratory function data including oropharyngeal leak pressure and peak airway pressure in these randomly selected SGA. Oropharyngeal leak pressure was measured by closing the expiratory valve of the circle system at fixed O2 flow 3L/min and noting the airway pressure at which the dial on a calibrated aneroid manometer reached equilibrium.
investigators wanted to compared the respiratory function between air-Q、i-gel、LMA-supreme、AMBU auragain、ProSeal LMA and other new SGAs during surgery and postoperative care unit.
