During nasotracheal intubation, the desired path of the tracheal tube is inferiorly along the nasal floor, beneath the inferior turbinate. Superior paths are suboptimal and may increase complications, including epistaxis and trauma to the ethmoid bone. To assess whether use of a nasogastric tube as a guide for insertion of the tracheal tube facilitates passage through the lower pathway, researchers randomized 60 patients undergoing oral and maxillofacial surgery with general anesthesia and neuromuscular blockade to nasogastric tube-guided or conventional, unguided insertion. The nasogastric tube was passed into the pharynx to approximately the 20-cm mark, the tracheal tube was inserted over it until the tracheal tube successfully turned cau…
