Before gastroscopy:
1. Smoking is prohibited on the first day, so as not to affect intubation when coughing during examination. Smoking can also reduce gastric acid secretion, which is convenient for doctors to observe.
2. Before the examination, the patient should be on an empty stomach for at least 6 hours. For example, he checked in the morning, fasted after dinner the day before, and dinner was free that day; If you check in the afternoon, you can eat light semi-liquid food for breakfast and fast at noon. Those who are seriously ill, weak and unable to take care of themselves after fasting should be injected with hypertonic glucose solution intravenously before examination.
3. In order to eliminate the patient's nervousness, reduce gastric juice secretion and gastric peristalsis, remove the foam in the stomach and make the image clearer, if necessary, the doctor should give the patient sedatives, spasmolytics and defoamers 20-30 minutes before the examination. This patient should know something about it and cooperate with it.
4. In order to make the gastroscope pass through the pharynx smoothly, pharyngeal anesthetic should be used before gastroscopy, and patients should follow the doctor's advice when taking medicine. The gastroscope mucilage currently used in our hospital has the dual functions of anesthetizing the pharynx and clearing the foam in the stomach, which is convenient, effective, odorless and easy for patients to accept.
Patients and doctors should cooperate. After entering the examination room, loosen the neckline and belt, take off the dentures and glasses, and take the left side position. Don't bite the mirror with your teeth after entering the mirror, so as not to bite the plastic pipe of the mirror body, and your body and head can't rotate, so as not to damage the mirror and hurt your internal organs. If there is discomfort, the patient can't bear it for a while, so he can signal the operator with his hand to take necessary measures.
After gastroscopy:
1. After the examination, the patient sat up and spit. Due to the injection of air during the examination, the patient will have abdominal distension or belching. Because the anesthetic effect of the pharynx has not disappeared, you can't eat for 2 hours after the examination. After 2 hours, you can try to eat liquid food first, and then gradually transition to other foods.
2. There may be throat pain or foreign body sensation, delicious iodine-containing throat tablets, grass coral buccal tablets, etc. Symptoms can be alleviated or disappeared.
3. Biopsy patients (especially the elderly) should eat semi-liquid diet within 1-2 days after the examination, avoid irritating diet, and pay attention to whether there is black stool. If there is black stool, please go to the hospital in time.
