Airway Management
Conditions
Brief summary
Laryngeal mask airway is used in different types of surgery requiring different position, recommendation was raised regarding the use of LMA in Lithotomy position with pressure controlled mode of ventilation. This raise a concern whether the mode of ventilation is a limitation for the use of LMA in these position, especially with the use of the i-gel LMA with the characteristic non-inflatable jelly cuff, that provides an excellent seal.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assess the safety of volume-controlled mode of ventilation.in the Lithotomy position during the procedure | During the Procedure | Measuring the air Leak through measuring the difference between the inspired and expired tidal volume and determine the peak airway pressure at which these leak does occur. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| THE incidence of complication among the two groups | through the procedure | decreased oxygen saturation, increased airway pressure, tachycardia, etc..) and confirmed radiologically, Failure of insertion or intubation, sore throat and air leak were reported as a complications. |
