The operation procedure of nasal feeding tube is mainly as follows: First, fully inform the patient of the importance and necessity of implanting nasal feeding tube before placing the tube, and gain the patient’s trust and understanding to facilitate the smooth operation of nasal feeding tube. 2. Ask the patient to relax, tilt the head to the side, and insert the nasal feeding tube slowly along the patient’s side of the nostril after applying paraffin oil evenly on the head end. When the nasal feeding tube reaches the epiglottis, ask the patient to do swallowing action or give the patient a small amount of warm water to help the nasal feeding tube enter into the esophagus smoothly. Once the nasogastric tube enters the esophagus, adjust the speed of entry appropriately, ask the patient to do swallowing action without stopping, stop the operation after the scale of the nasogastric tube reaches 60-65 cm, and fix the nasogastric tube to prevent it from falling off.
