Nasogastric intubation is performed to check for gastric reflux, relieve gastric distension, or administer enteral fluids, laxatives, or medications. Nasogastric intubation is achieved by directing and maintaining the nasogastric tube into the ventral meatus of the nasal cavity, without traumatizing the nasal turbinates and the ethmoid turbinates. The tube is blindly manipulated within the nasopharynx to the esophageal opening, avoiding the dorsal pharyngeal recess and the salpingopharyngeal plica. Once in the esophagus, the nasogastric tube is gently advanced aborally to enter the cardia of the stomach.

The blind manipulation and passage of the tube can result in trauma to the associated tissues along the intended pathway, and trauma to structures if the tube is misdirected. Misplacement of the tube can result in further problems (fragmentation of the tube or administration of fluid into the lungs) if not recognized.
