Tongue traction suture - ANSWER-When the tongue is obstructing the airway one or
two sutures can be placed through the dorsum of the tongue and grasped with a large
hemostat
Nasopharyngeal airway - ANSWER-Does not interfere with procedures
Well-tolerated
Can be used on awake patients
Passed through one of the nostrils into the nasal cavity into the oropharynx posterior to
the tongue.
Oropharyngeal airway - ANSWER-Oral airway
may be used to position the tongue in a more anterior position
interferes with intraoral procedures
not tolerated well in awake patients
Supraglottic airway - ANSWER-Placed above the level of the vocal cords
2 types: laryngeal mask airway (LMA) and I-gel supraglottic airway
Gastric port or small tube that passes through the length of the airway to allow access
for a suction catheter that can by used to remove fluid in the stomach and diminish
likelihood of aspiration of acidic gastric juices.
