Need for high pressure ventilation (the tighter seal of an endotracheal tube or a special LMA designed to form a tighter seal is needed for patients with excessive airflow resistance in the infraglottic airways or lungs) Complications of Laryngeal Mask Airway Insertion Complications include Vomiting and aspiration Tongue edema due to prolonged placement or balloon overinflation Dental or oropharyngeal soft tissue trauma during insertion Equipment for Laryngeal Mask Airway Insertion Gloves, mask, gown, and eye protection (ie, universal precautions) 30 - to 60-mL syringe Sterile water-soluble lubricant or anesthetic jelly Laryngeal mask airway Bag-valve apparatus Oxygen source (100% oxygen, 15 L / minute) Suctioning apparatus to clear the pharynx as needed Pulse oximeter, capnometer (end-tidal carbon dioxide monitor), and appropriate sensors Drugs to aid intubation Equipment for alternate methods of airway control should LMA insertion fail (eg, equipment for bag-valve-mask ventilation, endotracheal intubation, cricothyrotomy) Additional Considerations for Laryngeal Mask Airway Insertion The inflatable cuff around the rim of the mask forms a low-pressure seal around the laryngeal inlet that allows positive pressure ventilation.
