摘要

The laryngeal mask airway (LMA) is a supraglottic device essential for maintaining patency in unconscious patients. This study compares the classic blind insertion technique with a laryngoscope-assisted approach to evaluate insertion efficiency, complication rates, and provider satisfaction. This randomized clinical trial assigned 124 adult patients to either the classic (n = 62) or laryngoscope-assisted (n = 62) group. Outcomes included insertion time, success rates, mucosal trauma (blood on mask), gastric insufflation, and physician satisfaction. Physician satisfaction was significantly higher in the laryngoscope group (OR = 2.351, P = 0.025). While insertion time and gastric air presence were lower in the laryngoscope group, these did not reach statistical significance. Mucosal trauma (blood on mask) was slightly more frequent with laryngoscopy but without significant clinical morbidity. The laryngoscope-assisted method is a viable alternative to the classic approach, offering superior physician satisfaction and potentially reducing gastric complications.
