Design outcomes

Primary

Measure	Time frame
Proportion of participants with an oral wet score >= 3. The oral wet score will be rated on a 4-point scale using recorded AceScope video at the first laryngoscopy; two board-certified anesthesiologists will independently assess the images in a blinded manner. 1 (Excellent): No secretions; very dry (no pooling in the piriform fossae, vallecula, arytenoid region, or laryngeal vestibule). 2 (Good): Slightly moist without impaired view (mild pooling/bubbles in piriform fossae or vallecula; no pooling in the arytenoid region or laryngeal vestibule). 3 (Acceptable): Moist with partial interference but suction not required (pooling/bubbles up to the arytenoid region; no pooling in the laryngeal vestibule). 4 (Poor): Very wet with obscured view requiring suction (pooling present in the laryngeal vestibule). A score of >= 3 will be defined as wet.	—
