Enteral Nutrition I: Orogastric and Nasogastric Feeding

2.4K
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

    Summary

    This case report introduces the Tumguide, a new system for gastric tube placement during general anesthesia. The device uses light to help visualize the tube tip, potentially improving insertion accuracy in clinical settings.

    Area of Science:

    • Medical Devices
    • Gastroenterology
    • Anesthesiology

    Background:

    • Gastric tube insertion is crucial for patient care but traditionally involves blind placement.
