In the management of necrotizing enterocolitis, what is the primary purpose of nasogastric suction?

• A. To decompress stomach and intestines
• B. To deliver IV antibiotics
• C. To measure gastric residuals
• D. To feed the infant

Answer: (A)

In NEC, reducing distention of the gut is essential to protect blood flow and prevent further injury, and the nasogastric suction serves to accomplish that. A tube connected to continuous suction removes air, gastric secretions, and intestinal contents, which lowers intraluminal pressure and relieves bowel distention. This rest for the bowel helps improve perfusion, reduces the risk of progression to ischemia or perforation, and creates an environment for healing. It also helps prevent vomiting and aspiration. While clinicians can monitor the type and amount of aspirate, the main purpose is decompression. Antibiotics are given intravenously, not through suction, and the infant is kept NPO, so feeding via the tube would counteract the goal of bowel rest.
