Nasogastric feeding needs to pay attention to the prevention of blockage, nasal feeding position, pay attention to the observation of stool, etc.. 1. Preventing blockage: Nasogastric diet should not be too hot or too cold, and the temperature should be 38-40 degrees Celsius, so that the nasal feeding liquid does not feel hot when it is dripped on the inner part of the wrist. After feeding, each time inject 20-30ml of warm water to rinse the nasal feeding tube, and at the same time choose the food with low viscosity. 2. Nasogastric position: mainly in a low semi-recumbent position, elevate the head of the bed about 30°, and the nasal feeding speed should not be too fast. Prevent food reflux, resulting in aspiration. 3. Observe the stool condition: the gastric catheter needs to be changed once in 7-10 days under normal circumstances, and more attention should be paid to the patient’s stool pattern. Once there is dilute stool, odor, etc., then consider protein malabsorption, timely adjustment of dietary structure. If shortness of breath occurs during nasal feeding, it is recommended to consult a doctor for further examination and targeted treatment with the doctor’s help.
