The Application of a SaCoVLMTM Visual Intubation Laryngeal Mask for the Management of Difficult Airways in Morbidly Obese Patients: Case Report

Abstract

We report insertion of the SaCoVLMTM in three awake morbidly obese patients (BMI 46. 7–52.1 kg/m2). The patients were given intravenous atropine and midazolam injections after entering the operating room and then inhaled an anesthetic with 2% lidocaine atomization. After SaCoVLMTM insertion while patients were awake, when the vocal cords were visualized, controlled anesthetic induction commenced with spontaneous ventilation. The entire anesthesia induction and intubation process was completed under visualization, and no adverse events such as hypoxemia occurred. No patient had an unpleasant recall of the procedure. We conclude that the SaCoVLMTM is easy to use, well tolerated and suitable for awake orotracheal intubation in patients with known difficult airways.
