How to confirm that the gastric tube is in the stomach_How to check if the gastric tube is in the stomach

The gastric tube is inserted into the body of the person being examined. So how does the doctor judge whether the gastric tube has reached the stomach? In fact, this is also something that many friends understand. While injecting a small amount of air into the gastric tube with a syringe, place a stethoscope on the stomach for auscultation. If there is a sound of water flowing through, the gastric tube has reached the gastric tube.

Nasogastric tube (nasogastric tube, nasogastric feeding tube) Nasogastric tube is inserted through the nostrils, through the pharynx, and through the esophagus to reach the stomach. It is mostly used to extract gastric juice, and can also be used to inject liquid into the stomach to provide patients with necessary food and nutrition. During nursing, care should be taken to avoid contamination of the nasogastric tube and dislocation of the nasogastric tube, which may lead to aspiration.

There are three ways to check whether the gastric tube is inserted into the stomach :

Use a syringe to inject 10 to 20 ml of air into the gastric tube while placing a stethoscope on the stomach to listen. If there is a sound of air passing through water, it means that the gastric tube has entered the stomach.

If gastric juice or water is found when suctioning from the gastric tube with an empty syringe, it can also be judged.

Place the end of the gastric tube in water to see if any bubbles escape. There should be no air bubbles in the stomach.

When intubating, position the patient properly, clean and lubricate the nasal cavity. Tilt the patient's head back and insert the gastric tube at a 60° angle to the nostril, and continue to insert it into the nasopharynx; when the gastric tube is inserted to 15CM (pharynx), drip 1-2ML sterilized paraffin oil along the outer wall of the gastric tube, lift the patient's head, and make the lower jaw close to the chest wall to increase the curvature of the throat, so that the gastric tube can slide along the back wall and pass through the throat smoothly into the esophagus. At this time, ask the patient to swallow while slowly inserting the gastric tube to the required length and then fix it. Then check whether the gastric tube is in the stomach. After the gastric tube is successfully inserted, the gastric tube needs to be properly fixed. The method is:

First, use a 3cm long tape strip to wrap around the gastric tube twice to mark the nostrils, and then use a 6-7cm tape to cross and fix the nose wing. Then use a prepared cloth belt about 50-60cm long (1.5cm wide) to wrap around the gastric tube at the nostrils and tie a knot (do not affect the drainage of the gastric tube when tying the knot), and then pass both sides of the belt around the patient's head. Tie a slipknot on one side to strengthen the fixation of the gastric tube.
