If a newborn is suspected of having an abnormality of the digestive tract, the doctor will often recommend a gastrointestinal tract imaging for the newborn. The process of neonatal gastrointestinal tract imaging consists of several steps. First, the newborn’s gastrointestinal tract is prepared. Before the newborn is given a gastrointestinal tract imaging, it is often necessary to get the food out of the newborn’s intestinal tract. Parents can give the newborn magnesium sulfate orally or with other laxative drugs. After the food is expelled, the imaging will not be disturbed by the food. Next is the administration of contrast medication. Parents can give the newborn a contrast agent. After the newborn has ingested the contrast agent. The density of the contrast agent is very high. Therefore, the structure of the newborn’s intestine will be revealed after the newborn is given a contrast. Once the structure is clear, the newborn can be diagnosed with any abnormalities of the digestive tract. If the newborn has intestinal abnormalities, parents should take the newborn to the hospital for surgery in a timely manner.
