Direction for use

1. The LMA, should check with the specifications of product labeling.
2. To exhaust the gas in the airway of the laryngeal mask airway so that the hood is completely flat.
3. Apply a small amount of normal saline or water soluble gel for lubrication in the back of the throat cover.
4. The patient's head was slightly back, with his left thumb into the patient's mouth and traction of the patient's jaw, in order to widen the gap between the mouth.
5. Using the right hand to hold the pen holding the laryngeal mask, to make available, the index finger and middle finger finger against the cover connection body and the ventilation tube laryngeal mask, cover the mouth towards the direction along the midline of lower jaw, tongue sticking down pharyngeal LMA, until no longer advance so far. Also can use reverse the method of inserting laryngeal mask, just cover the mouth toward the palate, will be placed in the mouth to the throat at the bottom of the laryngeal mask, and 180O after rotation, and then continue to push down the laryngeal mask, until can't push so far. When using the enhanced or ProSeal laryngeal mask with guide rod, the guide rod can be inserted into the air cavity to reach the designated position, and the insertion of the laryngeal mask can be drawn out after the insertion of the laryngeal mask.
6. In the move before the other hand gently with finger pressing to prevent laryngeal mask airway catheter displacement.
7. According to the nominal charge to cover bag filled with gas (air amount can not exceed the maximum filling mark), connect the breathing circuit and assess whether good ventilation, such as ventilation or obstruction, should according to the steps of re insertion of laryngeal mask.
8. To confirm the position of the laryngeal mask is correct, cover the tooth pad, fixed position, maintain ventilation.
9. The throat cover is pulled out: the air behind the air valve of the syringe with the syringe without needle is pulled out of the throat cover.

Such as the discovery of thoracic or poor or non fluctuating amplitude fluctuations hear the leak sound, should immediately pull the laryngeal mask, after full oxygen again after implantation.
4. Positive pressure ventilation, airway pressure should not exceed 25cmH2O, or prone to leakage or gas into the stomach.
5. Patients with laryngeal mask should be fasting before use, in order to avoid the possibility of anti - flow induced aspiration of gastric contents during positive pressure ventilation.
