Nasogastric Intubation
Nasogastric Intubation
Nasogastric Intubation

For nasogastric intubation, a small, flexible plastic tube is passed through the nose or mouth into the stomach (nasogastric tube) or small intestine (nasoduodenal tube). Intubation typically causes gagging and nausea, so a numbing agent may be sprayed in the nose and back of the throat.

This procedure can be used for various purposes, such as

  • Removing a sample of stomach or intestinal contents

  • Continuously removing the contents of the stomach

  • Providing food

  • Helping doctors accurately place a feeding tube through the skin directly in the stomach or intestine
