简要总结
The second generation supraglottic airways have become the standard of care for positive pressure ventilation . The leak pressures determine their efficacy for ventilation and safety. The evaluation of leak pressures in different head and neck position will increase their clinical utility and avoid Endotracheal Tube placement for all surgeries involving changes in head and neck position. The patient shall benefit from smooth emergence, decreased requirement of narcotics and anesthetic agents and avoids airway instrumentation.

结局指标
主要结局
Oropharyngeal leak Pressure with head in the neutral, flexed, extended and rotated to left position
时间窗: Immediately after insertion intraoperatively, within 30 mins of insertion of LMA
次要结局
- Peak airway pressure(Immediately after insertion intraoperatively, within 30 mins of insertion of LMA)
- Expired tidal volume(Immediately after insertion intraoperatively, within 30 mins of insertion of LMA)
- End tidal CO2(Immediately after insertion intraoperatively, within 30 mins of insertion of LMA)
- Difference between inspired & expired volume(Immediately after insertion intraoperatively, within 30 mins of insertion of LMA)
- Difference between leak pressure & airway pressure(Immediately after insertion intraoperatively, within 30 mins of insertion of LMA)
- Time to insert SAD(From taking Laryngeal mask Airway in hand to Obtaining square shaped capnogram on the monitor,within 5 mins)
- successful placement in the first attempt(During insertion, within first 5 mins)
- failed placement of SAD(During Insertion, within first 10 mins)
