Can the LMA airway tube be used as a conduit for emergency resuscitation medications?
There have been very few reports of administering drugs through the LMA airway tube, with contrasting results. In one cadaver study, epinephrine was successfully delivered to the lungs in “reasonable” amounts. However, in 100 anesthetized patients using a special cannula, drugs were found in only 27% or patients. Therefore, drug dispersal through the LMA airway tube is not a reliable way to administer medications, but may be worth a try in a resuscitation patient without an endotracheal tube or venous access.
