Electronic gastroscopy is categorized into ordinary and painless, and patients who undergo ordinary electronic gastroscopy will find it a bit difficult. 1. Ordinary e-gastroscopy: it is carried out under the awake state of the patient. When the gastroscope is penetrated deep into the inner larynx, its larynx will be stimulated repeatedly, which is easy to induce muscle tension, nausea, vomiting and other stress reactions, resulting in physiological discomfort to the patient, so this kind of patients will find it a little bit hard to bear. 2. Painless e-gastroscopy: it is carried out in the state of anesthesia of the patient, therefore, there is no uncomfortable feeling in the process of examination, after the anesthesia disappears, there may be pain in the pharynx or a sense of foreign body, but the symptom will be reduced or disappear soon. At present, most patients will choose painless e-gastroscopy. If you choose ordinary e-gastroscopy, you can also optimize the position placement, professional technology, psychological guidance, environmental choices, etc., which can improve the cooperation of gastroscopy patients and reduce the pain.
