1. Prepare the supplies and bring them to the bedside.
2. Prepare the patient: The conscious person should make an explanation in order to obtain cooperation, and take the sitting or lying position. The comatose patient should lie down, put his head back later, put a treatment towel under the jaw, and check and clean the nasal cavity with a wet cotton swab. Prepare tape: two pieces of 6cm and one piece of 1cm. 3. Hold the gastric tube with the gauze in the left hand, and hold the vascular forceps in the right hand to clamp the length of the intubation tube at the front end of the gastric tube. For adults 45-55cm (earlobe-nose tip-xiphoid process), infants and young children 14-18cm, mark with 1 cm tape to lubricate the stomach tube.
3. The left hand holds the gauze to support the gastric tube, and the right hand holds the vascular clamp to clamp the front part of the gastric tube and slowly insert it along one nostril. When it reaches the pharynx (14-16cm), instruct the patient to swallow while sending the gastric tube down. If the patient develops nausea, the segment should be paused, and the patient should be instructed to take a deep breath or swallow and then insert the stomach tube 45-55cm to relieve discomfort. When the insertion is not smooth, check whether the gastric tube is in the mouth. If coughing, breathing difficulties, cyanosis, etc. are found during the intubation process, it means that the trachea has been inserted by mistake. It should be pulled out immediately and reinserted after a short rest.
4. The patient in a coma cannot cooperate due to the disappearance of swallowing and coughing reflexes. In order to improve the success rate of intubation, when the gastric tube is inserted to 15 cm (epiglottis), the dressing bowl can be placed next to the mouth, and the patient’s head can be held up with the left hand Make the lower jaw close to the stem of the sternum, and slowly insert the tube.
5. Verify whether the gastric tube is in the stomach.
5.1 Place the open end of the gastric tube in water. If a large amount of gas escapes, it proves to have entered the trachea by mistake.
5.2 Aspirate gastric juice with a syringe.
5.3 Inject 10cm of air with a syringe, and listen to the sound of water in the stomach with a stethoscope.
6. Fix the gastric tube on both sides of the nose with tape, connect the syringe at the open end, withdraw first, and see that gastric juice is drawn out, first inject a small amount of warm water-inject fluid or medicine-and then inject a small amount of warm water to clean the lumen. During feeding, prevent air from entering.
7. Raise the end of the stomach tube and fold it up, wrap it with gauze and wrap it tightly with a rubber band, and fix it next to the patient’s pillow with a pin.
8. Organize the unit, tidy up supplies, and record the amount of nasal feeding.
9. When extubating, fold and clamp the nozzle with one hand.
