Things to note before gastroscopy

Gastroscopy is a tool we use to examine the stomach. The emergence of gastroscopy has brought us a lot of convenience when examining stomach diseases. Using gastroscopy to examine the stomach can not only expand the field of vision but also ensure safety. Gastroscopy is simple and comfortable to operate. However, there are still many aspects that we need to pay attention to when using gastroscopy to examine the body.

There are many details that we need to pay attention to before doing a gastroscopy. If we do not pay attention to these links, the effect of gastroscopy on the stomach will be much worse. Let’s take a look at the detailed introduction below.

1. Do not smoke the day before the examination to avoid intubation affected by coughing. Not smoking can also reduce gastric acid secretion, making it easier for doctors to observe.

2. The patient must fast for at least 6 hours before the examination. If the examination is conducted in the morning, the patient must fast after dinner the day before and skip dinner on the day of the examination. If the examination is conducted in the afternoon, the patient can have a light semi-liquid breakfast and must fast at noon. Patients with severe illness or weak constitution may have difficulty supporting themselves after fasting, and hypertonic glucose solution should be injected intravenously before examination.

3. In order to eliminate the patient's nervousness, reduce gastric juice secretion and gastric motility, remove gastric foam, and make the image clearer, the doctor should give the patient sedatives, antispasmodics and defoaming agents 20-30 minutes before the examination if necessary. Patients should understand this and cooperate with it.

4. In order to allow the gastroscope to pass through the pharynx smoothly, pharyngeal anesthetics are generally administered before gastroscopy. When taking the medication, the patient must follow the doctor's instructions. The gastroscopy glue currently used in our hospital has the dual functions of anesthetizing the pharynx and removing gastric foam. It is convenient, effective, odorless, and easy for patients to accept.

5. The patient should cooperate with the doctor. After entering the examination room, he should loosen his collar and belt, take off his dentures and glasses, and lie on his left side. After inserting the mirror, you should not bite it with your teeth to avoid biting the plastic tube of the mirror body. Your body and head should not be turned to avoid damaging the mirror and injuring your internal organs. If there is any discomfort, the patient can endure it for a while. If he can no longer bear it, he can use gestures to signal the operator so that necessary measures can be taken.
