|---|---|---|---|
| Primary | Proportion of Patients With Optimal Video LMA Position (Brimacombe-Berry Score 4) | Immediately after video laryngeal mask airway insertion (within 3 minutes of insertion) | After insertion, a blinded investigator will evaluate the hypopharyngeal view through the integrated videoscope of the video laryngeal mask airway and grade device position using the Brimacombe-Berry scale (0-4): 4 = only vocal cords visible (optimal); 3 = vocal cords and posterior epiglottis visible; 2 = vocal cords and anterior epiglottis visible; 1 = vocal cords not visible but device functional; 0 = device not functional. Higher scores indicate better positioning. The outcome is the percentage of patients with a score of 4 in each group. |
| Secondary | Oropharyngeal Leak Pressure | Immediately after successful video laryngeal mask airway insertion | Oropharyngeal leak pressure will be measured after successful placement of the video laryngeal mask airway to assess airway sealing efficacy. The pressure will be recorded in cmH2O and compared between the rocuronium and control groups. |
| Secondary | Video Laryngeal Mask Airway Insertion Time | During video laryngeal mask airway insertion | Time (seconds) from the moment the investigator places a hand on the patient's chin until the hand is removed from the video laryngeal mask airway after insertion. |
| Secondary | First-Attempt Insertion Success Rate | During video laryngeal mask airway insertion | Percentage of patients in whom the video laryngeal mask airway is successfully inserted on the first attempt. Successful ventilation will be confirmed by an appropriate capnographic waveform. |
| Secondary | Number of Video Laryngeal Mask Airway Insertion Attempts | During video laryngeal mask airway insertion | The total number of attempts required to achieve successful video laryngeal mask airway placement will be recorded for each patient and compared between groups. |
| Secondary | Insertion Difficulty Score | Immediately after video laryngeal mask airway insertion | Difficulty of insertion rated by the inserting investigator on a 0-100 mm visual analog scale (0 = extremely easy, 100 = extremely difficult). |
| Secondary | Hemodynamic Parameters | From anesthesia induction to completion of video laryngeal mask airway insertion | Lowest and highest heart rate (beats/min), blood pressure (mmHg) recorded during video laryngeal mask airway insertion. |
| Secondary | Airway Pressures | 5 minutes after initiation of mechanical ventilation | Peak airway pressure (Ppeak, cmH2O), mean airway pressure (Pmean, cmH2O) recorded from the mechanical ventilator. |
| Secondary | Ventilation Leak Volume | 5 minutes after initiation of mechanical ventilation | Leak volume (mL), calculated as the difference between inspired and expired tidal volumes recorded from the mechanical ventilator. |
| Secondary | Insertion-Related Airway Complications | During video laryngeal mask airway insertion | Percentage of patients experiencing airway bleeding, laryngospasm, or oxygen desaturation during video laryngeal mask airway insertion. Each complication will be recorded as present or absent. |
| Secondary | Postoperative Complications | 20 minutes and 6 hours after surgery | Presence or absence of sore throat, hoarseness, dysphagia, nausea and vomiting assessed by face-to-face interview. Results will be reported as the percentage of patients with complication. |
