Silicone Laryngeal Mask use method and operation procedure

　　Silicone Laryngeal Mask is a special type of ventilator, also known as a laryngeal mask ventilator, as it can be used to cover the throat with a flat long shaped sleeve made of silicone rubber. Silicone Laryngeal Mask is an effective means of establishing respiratory airway during general anesthesia surgery, which is suitable for patients with general anesthesia, emergency departments, ICU, emergency and resuscitation patients, patients with airway difficulties, and patients with throat lesions.

　　Characteristics of Silicone Laryngeal Mask

　　Easy to use, easy to place and fix, can quickly establish artificial airway, high placement success rate;

　　Double safety, anti-aspiration, small irritation, can avoid throat and trachea mucous membrane damage;

　　The laryngeal hood is curved at 90 degrees and is designed with a vent tube and drainage tube, which can be inserted into the stomach tube to drain gastric fluid and prevent bloating and reflux aspiration. The dual balloon design makes the vent hood more consistent with the laryngeal anatomy and better sealing performance. The distal end of the laryngeal mask is located in the esophageal opening, easy to fix, not easy to shift.

　　Silicone Laryngeal Mask placement method

　　With the patient's head slightly tilted back, the operator holds the laryngeal mask facing the patient with his right hand, and pulls the patient's chin with his left hand to expand the oral space and see the oral throat. Place the mouth of the mask toward your chin and down the midline of your tongue against the back wall of your throat until you can't push it forward any further and make sure the mask is not folded.

　　The optimal placement for Silicone Laryngeal Mask

　　The Silicone Laryngeal geal Mask enters the laryngeal cavity, with the lower end of the Laryngeal Mask entering the upper mouth of the esophagus, the upper end of the laryngeal mask is close to the bottom of the ventral surface of the epiglotic surface, and the vent in the laryngeal mask points to the glottis. After inflating the air bag around the laryngeal mask, a closed loop can be formed in the larynx, so as to ensure the ventilation effect.

　　After Silicone Laryngeal Mask was inserted, positive pressure ventilation was needed to observe the heaving degree of the chest, whether the breathing sounds on both sides of auscultation were symmetrical and clear, and whether there was air leakage noise in the anterior neck area.
