Patients with gastric bleeding need to be hospitalized and cannot blindly buy medication on their own to avoid delaying the condition and causing gastric bleeding, which can aggravate the condition and may even endanger the patient’s life with hemorrhagic shock. After hospitalization, patients with gastric bleeding need to cooperate with the doctor to do relevant examinations, such as venous blood sampling, stool routine, occult blood test, electrocardiogram, electronic gastroscopy, abdominal ultrasound, CT and other related examinations to help clarify the specific cause of gastric bleeding, and the severity of gastric bleeding. At the same time, it is necessary to cooperate with the doctor to give active treatment, such as acid suppression, hemostasis, blood transfusion, rehydration and other symptomatic supportive treatment. The commonly used acid suppressants are omeprazole and lansoprazole injection, and the main drugs used for hemostasis are growth inhibitors and oxytetracycline injection.
