简要总结
The purpose of this study is to compare two insertion techniques of large size ProSeal laryngeal mask airway. We hypothesized that insertion of ProSeal laryngeal mask airway with 90-degree rotation would reduce the contact surface between the device and pharyngeal wall and make it easy to advance the device over the smooth angle against the posterior pharyngeal wall.We compared the success rate and incidence of complication of the standard technique with the rotational technique.
详细描述
ProSeal laryngeal mask airway is not easy to be inserted due to its larger cuff especially in Asian population. First-time insertion success rate was lower and more time was required to achieve an effective airway even in well-trained physician. A number of techniques have been described to improve the insertion success rate. However, these techniques are only recommended to be used as backup when the digital or introducer tool techniques fail. We hypothesized that insertion of ProSeal laryngeal mask airway with 90-degree rotation would reduce the contact surface between the device and pharyngeal wall and make it easy to advance the device over the smooth angle against the posterior pharyngeal wall.We compared the success rate and incidence of complication of the standard technique with the rotational technique.

研究组 & 干预措施
Standard technique
Proseal laryngeal mask airway was inserted according to the manufacture's instruction manual (insertion with help of index finger insertion)
干预措施: Insertion fo ProSeal laryngeal mask airway (Procedure)
Rotational technique
The entire cuff of the PLMA was placed in the mouth without finger insertion in a midline approach and was rotated 90 degrees counterclockwise around the tongue. The PLMA was then advanced and rotated back until resistance was fel
