Contraindications of gastroscopy

I believe that for many people with bad stomachs, gastroscopy should not be unfamiliar, because gastroscopy is necessary in the lives of people with bad stomachs. The purpose of gastroscopy is to help people with stomach problems determine whether they have any stomach disease. Gastroscopy can be performed on most people, but not everyone can do it. Gastroscopy also has certain contraindications, which is an aspect that many people are concerned about.

One thing everyone knows is that you cannot eat or drink before having a gastroscopy. This is also to ensure the accuracy of the results of the gastroscopy. In addition, there are many other things to pay attention to for people undergoing gastroscopy. So, let’s talk in detail about the contraindications of gastroscopy.

Contraindications of gastroscopy:

1) In principle, the contraindications are the same as those for conventional gastroscopy.

2) Have a history of drug allergy, especially allergy to sedatives.

3) Pregnant and lactating women.

4) Diseases that can easily cause suffocation, such as bronchitis causing excessive sputum, gastric retention, and acute upper gastrointestinal bleeding causing excessive blood retention in the stomach.

5) People with severe snoring or obesity should use this product with caution.

6) Be cautious if you have bradycardia.

Precautions

During a gastroscopy, in order to clearly see the mucous membrane of the digestive tract, the area being examined must be very clean, with no food or blood clots remaining. If you have a gastroscopy in the morning, do not eat or drink, and do not smoke after 8 pm the night before the examination. Eat food with less residue and easy to digest for dinner the day before. Because even if the patient drinks a small amount of water, the color of the gastric mucosa can change. For example, in the case of significant atrophic gastritis, the gastric mucosa can turn red after drinking water, which can lead to errors in diagnosis. If the gastroscopy is performed in the afternoon, the patient can drink some sugar water before 8 am that day, but cannot eat anything else and must not eat at noon. If the patient has pyloric obstruction, gastric lavage must be performed the night before the examination to thoroughly clean the gastric contents until the flushing reflux fluid is clear. After gastric lavage and before the gastric tube is removed, the patient should lie in a supine position with his head low and feet high to allow the remaining fluid in the stomach to be completely discharged. Gastric lavage should not be performed on the same day because it can change the color of the gastric mucosa. If a barium meal examination has been done, the barium may be attached to the gastrointestinal mucosa, especially the site of ulcer lesions, making fiber gastroscopy diagnosis difficult. Therefore, gastroscopy must be performed 3 days after the barium meal examination. At the same time, in order to reduce saliva secretion, reduce reflexes and reduce tension, inject 0.5 mg of atropine and 10 mg of diazepam or 0.1 g of luminal 15 to 30 minutes before the examination, and drink 2 to 3 ml of defoaming agent after the injection.

Through the introduction in the above article, we can't help but know some common contraindications of gastroscopy, which are generally manifested as: drug allergy, pregnant and lactating women, diseases that can easily cause suffocation, severe snoring patients, etc. For these people, gastroscopy is generally not allowed to avoid unnecessary damage, because gastroscopy is still dangerous for these people.
