Home Care Methods for Nasogastric Feeding in Elderly Patients

Many elderly individuals, due to diminished swallowing and chewing functions, require nasogastric (NG) tube placement. When taking the NG tube home, caregivers must possess basic nursing knowledge.

First, patients receiving enteral feeding via NG tube must not lie flat; the head of the bed should be elevated to at least 30°. Why? 1. Lying flat significantly increases the risk of gastroesophageal reflux. Due to age-related declines in swallowing function and impaired laryngeal reflexes, elderly patients are highly susceptible to aspiration. Therefore, it is recommended that the head of the bed be elevated 30°–45° at home for patients receiving NG feeding.

Second, temperature control is critical. Before administering the feeding solution, verify its temperature—ideally, it should feel warm but not hot when dripped onto the back of the hand. Administer the feeding only after confirming appropriate temperature. Before and after each feeding, flush the NG tube with 20–30 mL of lukewarm water to assess for any adverse reactions. Finally, ensure all residual feeding solution within the tube is fully instilled to prevent tube occlusion.

Carefully protect the tube’s fixation site and discourage the patient from touching or pulling at it. Many patients experience discomfort and may inadvertently dislodge the tube. If displacement of the NG tube is observed—for instance, if the external portion appears longer than usual or if the tube no longer sits securely at its fixed position—immediately seek medical evaluation or consult a healthcare professional to confirm proper intragastric placement before resuming feeding. Feeding must never be resumed if tube positioning is uncertain, as misplacement risks aspiration of feed into the lungs, potentially leading to life-threatening airway obstruction or asphyxiation.
