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.
Video laryngeal masks (VLMAs) are frequently used in airway management. Especially in surgical procedures lasting longer than one hour, VLMA cuff pressure, positive pressure ventilation, and airway manipulations are associated with postoperative sore throat and changes in middle ear pressure. The aim of this study is to evaluate the effect of neuromuscular blocker (rocuronium) administration on postoperative sore throat during video laryngeal mask use in surgical procedures lasting longer than one hour. Furthermore, it aims to examine its effects on changes in middle ear pressure, oropharyngeal leak pressure, and airway-related clinical parameters.

Samsun City Hospital

RECRUITINGPostoperative sore throat
Postoperative sore throat will be assessed using NRS (0: no pain, 10: most severe pain).
Time frame: 24 hours
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
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
video laryngeal mask airway placement time
Video laryngeal mask airway placement time will be recorded after induction.
Time frame: 2 minutes after induction
