简要总结
There are some differences between elderly and young adult patients regarding the anatomy of upper airways. Elderly patients have larger upper airways than young adult patients at all pharyngeal levels as revealed by CT. Another study explained that there is a progressive descent of the larynx and epiglottis with aging, which lengthens the upper airway and possibly makes it more likely to collapse.
The aim of this study is to compare the clinical efficacy of laryngeal mask airway (LMA) in elderly patients with young adults. In this study, the investigators will measure the ease of insertion, success rate of insertion, the time of insertion, oropharyngeal leak pressure, gastric leak pressure, fiberoptic position and intraoperative complications of the classic LMA.

结局指标
主要结局
oropharyngeal leak pressure
时间窗: 24 hours
After successful placement of LMA, airway leak pressure was determined by adjusting the expiratory valve of the breathing circle to 40 cmH2O(fixed fresh gas flow 3 L/min) and recording the pressure when equilibrium was reached.
