How can you alleviate the pain and what should you pay attention to when doing gastroscopy?

Hello, we usually pay attention to the following aspects before gastroscopy:

First, in order to prevent hepatitis infection, hepatitis patients and non-hepatitis patients are separated during gastroscopy, and liver function and hepatitis B surface antigen are usually checked before gastroscopy.

Second, in order to clearly see the mucosa of the digestive tract, it is necessary to make the examined part very clean, and there can be no food or blood clots left.

Do gastroscopy in the morning: after 8 o'clock the night before, don't eat, drink or smoke. Eat less residue and digestible food for dinner the night before. Because even if patients drink a small amount of water, they can change the color of gastric mucosa, such as the true color of obvious atrophic gastritis, and the gastric mucosa can turn red after drinking water, which makes the diagnosis wrong.

Do gastroscopy in the afternoon: patients can drink some sugar water before 8 am, but they can't eat anything else and don't eat at noon. For example, patients with pyloric obstruction must undergo gastric lavage the night before the examination, and the contents of the stomach must be thoroughly cleaned until the reflux of gastric lavage is clear. After gastric lavage and before pulling out the gastric tube, the patient takes a supine position with his head down and his feet high, so that the residual liquid in the stomach can be completely discharged. Gastric lavage is not allowed on that day, because gastric lavage will change the color of gastric mucosa.

Have done barium meal examination: This barium meal may be attached to gastrointestinal mucosa, especially the ulcer lesion, and it is difficult to diagnose by fiberoptic gastroscopy, so gastroscopy must be done 3 days after barium meal examination.

3. In order to reduce saliva secretion, reflex and tension, atropine 0.5 mg and diazepam 10 mg or lumina 0. 1 g 65438+30 ml were given 30 minutes before the examination, and then 2 ~ 3 ml defoamer was drunk after the injection.

Fourth, local anesthesia is used for anesthesia, limited to the upper end of the throat and esophagus. Before using the above drugs, explain your drug allergy history to your doctor, that is, what drugs you were allergic to in the past.

Local anesthesia is to spray 2% dicaine or 2% serum caine, and the patient opens his mouth and sounds "A". At this time, the soft palate and lingual palatal arch move up, and the base of the tongue moves down, so that the medicine is sprayed on the back of the tongue, throat and soft palate. After each spray, the patient swallows the medicine left in his mouth to anesthetize his throat. Paste is also used, which is contained in the mouth to make the medicine stay in the throat and naturally flow into the esophagus to play a local anesthetic role.

Patients and doctors should cooperate. Before the examination, the patient should urinate and empty his bladder. After entering the examination room, loosen the neckline and belt, take off the dentures and glasses, take the left lateral position, or switch to other positions as needed. After entering the mirror, don't bite the mirror with your teeth to avoid biting the plastic pipe of the mirror body. The body and head can't rotate, so as not to damage the mirror and hurt the internal organs. If there is discomfort, the patient can't bear it for a while, and can signal the operator (doctor or nurse) to take necessary measures.

After gastroscopy:

After the examination, the patient sat up and spit. Because some air was injected during the examination, although it was sucked out when the mirror was removed, some people still felt abdominal distension and a lot of belching. Because the anesthetic effect has not disappeared, eating too early is easy to make food enter the trachea, so try to eat liquid food 2 hours after the anesthetic effect of the pharynx disappears. During 1 ~ 4 days, the patient may feel discomfort or pain in the throat, but it does not interfere with the diet. Most people can work as usual, and seriously ill people can rest. The driver can't drive alone that day. It's best to have a family member accompany you to have a gastroscope and escort you home after the examination.

Contraindications of gastroscopy:

Some diseases can't be detected by gastroscopy, such as spinal deformity, unconsciousness, psychosis, cor pulmonale, asthma, hypertension and patients that doctors think are not suitable for gastroscopy.
