About this trial

Video laryngeal masks (VLMAs) are increasingly used as a minimally invasive alternative in airway management. The use of neuromuscular blocking agents can affect VLMA placement and airway physiology. As a result, there may be differences in postoperative respiratory complications and middle ear pressure.

Trial outcomes

Primary outcomes

1

Postoperative sore throat

Postoperative sore throat will be assessed using NRS (0: no pain, 10: most severe pain).

Time frame
24 hours

Secondary outcomes

1

Changes in middle ear pressure

In this study, middle ear pressure will be assessed using tympanometry during the preoperative period, immediately after induction of anesthesia, following endotracheal intubation, and at the 3rd and 5th minutes thereafter.

Time frame
1 hour
2

Oropharyngeal leak pressure

Oropharyngeal leak pressure (OLP) was measured by closing the adjustable pressure-limiting (APL) valve with a fresh gas flow of 3 L/min, and the airway pressure at which an audible leak occurred or the manometer pressure reached a plateau was recorded as the OLP (cmH₂O).

Time frame
during surgery
3

video laryngeal mask airway placement time

Video laryngeal mask airway placement time will be recorded after induction.

Time frame
2 minutes after induction
