Digestive tract bleeding is mainly observed

Digestive tract bleeding is mainly observed for bleeding nature, bleeding volume, vital signs and defecation nature, as follows: 1. Bleeding speed: Hematemesis is a common manifestation of patients with digestive tract bleeding. The patient vomits brown or coffee blood, which means that the bleeding speed is slow. If the bleeding volume is fast, it is short-term vomiting of a large amount of bright red blood accompanied by blood clots, so as to preliminarily judge the bleeding speed of patients. Bleeding volume: If the patient bleeds between 5 and 50 ml, no abnormal stool color can be observed with the naked eye. If the patient has hematemesis, it means that the blood in the stomach is greater than 250 ml, the short-term bleeding volume is greater than 400 ml, and it can also cause dizziness, fatigue and palpitations in the patient. If the bleeding volume is greater than 1000 ml, it can cause shock symptoms in the patient, such as decreased blood pressure, accelerated heart rate, cold limbs, pale face and confusion. 3. Vital signs: Some patients with large amount of short-term hematemesis may cause shock reaction. At this time, it is necessary to closely monitor the patient's vital signs, usually observe blood pressure, heart rate in combination with the patient's face, limbs, spirit and other symptoms to determine whether shock. 4. Nature of defecation: By observing the frequency of black stool, whether there is blood stool and the activity degree of bowel sounds, it is judged whether there is complicated lower gastrointestinal bleeding. If there is complicated lower gastrointestinal bleeding, targeted treatment should be carried out according to the cause of the patient, such as ligation therapy for hemorrhoids patients, endoscopic resection for polyps patients, endoscopic hemostasis for vascular lesions patients, etc.
