Nasointestinal tube placement procedure steps

Nasojejunal intubation is a technique for delivering enteral nutrition through nasal feeding, suitable for patients unable to eat due to symptoms such as swallowing difficulties or impaired consciousness. It is recommended to undergo the procedure at a正规 hospital under the guidance of a qualified physician. The specific steps are as follows:

1. The patient should lie flat. After the physician connects the nasojejunal tube and the suction container, lubricate the tube with liquid paraffin.

2. Gradually insert the nasojejunal tube through one of the patient's nostrils. During this process, the patient should continuously perform swallowing motions or sip small amounts of warm water to help guide the tube into the gastrointestinal tract.

3. The patient should breathe deeply, remain relaxed, and avoid tension during tube insertion to ensure smooth placement to the appropriate depth.

4. Once the nasojejunal tube has been inserted 55–60 cm, secure the nasal tube in place. The physician will provide individualized advice and precautions based on the patient’s specific condition.

Maintain continuous patency of the nasojejunal tube by flushing it regularly with warm water or sodium bicarbonate solution. Check frequently whether the adhesive tape securing the tube is loose, and replace it promptly if necessary. When the patient is moving or active, take care to protect the nasojejunal tube from being pulled or snagged by surrounding objects. When administering food, choose thin, low-residue formulas, and carefully consider factors such as food temperature and potential interactions between different substances.
