What the trial is, and whether it could suit you

The laryngeal mask airway (LMA) is a supraglottic ventilation device designed according to human anatomy. It was developed in 1981 by Dr. Archie Boubrain in the United Kingdom to compensate for the deficiencies of tracheal intubation and mask ventilation. It has been widely used in clinical practice because of its simple operation, small airway stimulation, and hemodynamic stability. In 1990, LMA entered the Chinese market. In 1993, LMA was included in the American Society of Anesthesiologists guidelines for the emergency management of the difficult airway. In the past, tracheal intubation was the standard method of airway control during general anesthesia. In the past decade, the proportion of LMA ventilated general anesthesia has increased significantly in China and European and American countries. By 2022, the utilization rate of LMA in China climbed to 95.96%. With the continuous imp
