Final answer:
Tracheal intubation is a procedure used to establish a patent airway. It is indicated for various reasons, excluding a full stomach. Regurgitation and aspiration of stomach contents pose a risk during intubation.
Step-by-step explanation:
Tracheal intubation is a medical procedure used to establish and maintain a patent airway in patients who are unable to breathe adequately on their own. It involves the insertion of a tube into the trachea, bypassing any obstruction and allowing for artificial ventilation. There are several indications for tracheal intubation, including a surgical procedure requiring paralysis and general anesthesia, external compression from a mass or bleeding, and inadequate spontaneous ventilation.
However, one of the indications EXCEPTed from tracheal intubation is a full stomach. This is because in patients with a full stomach, there is an increased risk of regurgitation and aspiration of stomach contents into the lungs during intubation.
