The laryngeal mask ventilation tube interface was connected to the breathing and ventilation was good, the airway pressure was not high, and there was no leakage. The first tooth pad 102a, the second tooth pad 102b and the laryngeal mask were wrapped together with adhesive tape and fixed to the patient's face. The patient underwent lithotomy surgery, which went smoothly. The laryngeal mask did not shift during the operation. After the operation, the negative pressure suction device sucked the gastrointestinal decompression tube 202 to draw out a small amount of clear gastric juice. When the patient was fully awake from anesthesia, consciousness was restored, spontaneous breathing was stable, and he could open his eyes and raise his head as instructed by the doctor, the fixing tape was torn off, and the laryngeal mask anti-shift mechanism and gastrointestinal decompression device were removed together with the laryngeal mask. The patient did not have any discomfort such as throat pain and hoarseness after the operation.
