? Experts from Beijing Tianan Traditional Chinese Medicine Hospital pointed out: Gastric bleeding is a relatively serious symptom of the stomach. Many people do not know much about it. When gastric bleeding occurs, they are often very nervous and do not know what to do. In this case, , first go to the hospital for a detailed examination to find out the cause before treatment. So? 1. Laboratory examination: When gastric bleeding occurs, key laboratory tests should include blood routine, blood type, clotting time, stool or vomit blood test (radionuclide or immunological blood test if possible), liver function and Tests of serum creatinine and urea nitrogen, etc. If possible, hematocrit should be measured. 2. Special examinations: 1. Barium X-ray: Although the diagnostic value of endoscopy is superior to barium X-ray, it cannot replace it. Because some anatomical parts of the intestine cannot be seen by ordinary endoscopes, and because some endoscopists are inexperienced, lesions are sometimes missed. These can be remedied by X-ray barium examination. However, barium angiography should not be performed too early after active bleeding, otherwise it may cause rebleeding or worsen bleeding due to pressing the abdomen. It is generally recommended to perform the procedure 3 days after the bleeding has stopped and the condition has stabilized. 2. Selective arteriography: a supplementary examination when the above diagnosis cannot be confirmed, and has more diagnostic value for vascular malformations. 3. Thread-containing capsule test: It has certain value in locating bleeding caused by lesions in the distal duodenum and proximal jejunum. 4. Radionuclide scan: For cases with negative endoscopic and X-ray examinations, radionuclide scan can be performed. The method is to label the patient's red blood cells with a radionuclide (such as Technetium 99m), and then inject it into the patient's body through the vein. When there is active bleeding and the speed can reach 0.1ml/min, the radionuclide can display the bleeding site and the monitoring time can be up to 24 hours. Experience has shown that if this test is negative, selective arteriography is often negative. Diagnostic methods for gastric bleeding: Gastric juice analysis: Gastric juice analysis refers to extracting gastric juice to measure and examine relevant indicators to determine whether the gastric juice is normal. It mainly includes general physical examination, chemical examination and microscopic examination. The above is a relevant introduction to "". I hope it will be helpful to you.
