Survey of laryngeal mask airway usage in 11,910 patients: safety and efficacy for conventional and nonconventional usage.
A survey of laryngeal mask airway (LMA) usage was conducted to provide general information about safety and efficacy with special emphasis on controversial issues such as positive pressure ventilation (PPV), prolonged anesthesia, and laparoscopic and nonlaparoscopic intraabdominal surgery. During the 2-yr study period, of the 39,824 patients who underwent general anesthesia, 11,910 (29.9%) patient airways were managed with the LMA. Forty-four percent underwent PPV. ⋯ There were three cases of failed tracheal intubation managed with the LMA. This survey demonstrates that the LMA technique is safe and effective for both spontaneous and controlled ventilation. Use of the LMA for gynecologic laparoscopy, gynecologic laparotomy, and procedures > 2 h also appears safe.
