Safety and Limitation of the 2nd Generation Laryngeal Mask Airway in the Lithotomy Position: An Obsevational Study

N/ACompletedNCT05920447

Ain Shams University60 enrolled

Overview

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.

Outcomes

Primary Outcomes

Assess the safety of volume-controlled mode of ventilation.in the Lithotomy position 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.

Time frame: During the Procedure

Secondary Outcomes

THE incidence of complication among the two groups

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.

Time frame: through the procedure
