How to check gastric bleeding?

Gastric bleeding is a disease with a relatively large patient base in life, but most of the patients with gastric bleeding are caused by gastric ulcer or duodenal ulcer. The most typical early symptoms of gastric bleeding are vomiting blood and black stools. If you find yourself having these two symptoms, you must go to the hospital for timely examination. So the question is, how to check gastric bleeding in the hospital?

1. Laboratory tests

In case of acute gastrointestinal bleeding, key tests should include routine blood tests, blood type, clotting time, occult blood test in stool or vomitus, liver function, blood creatinine, urea nitrogen, etc.

2. Special inspection methods

(1) Endoscopic examination

Direct observation through gastroscopy can confirm the condition and give appropriate hemostatic treatment according to the condition of the lesion. There are several points to note when doing fiber gastroscopy: ① The best time to perform gastroscopy is within 24 to 48 hours after bleeding. ② For patients in hemorrhagic shock, blood volume should be replenished first, and it is safer to perform gastroscopy after the blood pressure has stabilized. ③ Generally, there is no need to prepare for gastric lavage in advance, but if there is excessive bleeding and it is estimated that blood clots will affect observation, gastric lavage with ice water can be used for examination.

(2) Selective arteriography

In some special cases, such as when the patient is in an emergency state of continuous severe and massive upper gastrointestinal bleeding, so that gastroscopy cannot be performed safely or the bleeding focus cannot be identified due to blood accumulation affecting the visual field, selective mesenteric artery angiography may reveal the bleeding site and perform embolization therapy.

(3) X-ray barium angiography

Because some anatomical parts of the intestine cannot be visualized by conventional endoscopy, lesions are sometimes missed, which can be remedied by barium X-ray examination. However, barium angiography should not be performed too early after active bleeding, otherwise it may cause rebleeding or aggravate bleeding due to pressing the abdomen. It is generally recommended to operate with caution after the bleeding stops and the condition stabilizes for 3 days. Arteriography and endoscopic examination.

(4) Radionuclide scanning

For cases with negative endoscopic and X-ray examinations, radionuclide scanning can be performed. The method is to use radionuclides (such as 99mtechnetium) to label the patient's red blood cells, and then inject them into the patient's body through the vein. When there is active bleeding and the bleeding rate can reach 0.1ml/minute, the radionuclides can show the bleeding site.

If gastric bleeding is confirmed after examination, in addition to medication, special attention should also be paid to diet. If you have millet at home, you can ask your family to cook some millet porridge, which can nourish the stomach. However, when cooking millet porridge, do not add black rice or mung beans. These foods are difficult to digest and will aggravate the condition.
