Nasogastric intubation is a medical procedure where a plastic tube (NG Tube) is inserted through the nose, past the throat, and placed in the stomach. It’s used to deliver medication or food, and can also extract the contents of the stomach. However, instead of going into the esophagus, the NG Tube can go down the trachea and into a lung. Misplacement can lead to tissue trauma along the tract, esophageal perforation, or aspiration. To verify correct placement of the NG Tube, the current gold standard is radiography. The issues associated with radiography are long wait times and exposure to radiation. Other proposed alternatives have not been cost-effective enough to replace the X-ray. Here we look into developing a replacement to the current standard by using a hand-held metal detector (HHMD) along with a modified metal tipped NG Tube to verify placement.
