The common complications of peptic ulcer are perforation and bleeding, both of which are emergencies in general surgery. A large amount of blood loss in a short period of time, hemorrhagic shock caused by insufficient limited circulating blood volume, seriously endangering life.

Suggestion: In this case, the first thing is to replenish blood volume, such as blood transfusion, colloid fluid and crystalloid fluid according to the situation, and at the same time actively treat the primary disease to prevent further bleeding, and timely surgical treatment if necessary.

1. The patient has allergic reaction to blood transfusion.

2.① If there is allergic reaction, slow down the blood transfusion and continue to observe; In severe cases, stop blood transfusion immediately and keep the venous access unobstructed;

② Subcutaneous injection of 0.5mL of 0. 1% epinephrine, antiallergic drugs, glucocorticoids, etc.

③ Patients with dyspnea should take oxygen, tracheotomy should be performed when laryngeal edema is serious, and those with anaphylactic shock should be actively treated with anti-shock.

Gastric ulcer is a kind of peptic ulcer, which occurs in hernia of gastric horn, antrum, cardia and esophageal hiatus. Endoscopy is recommended. First of all, we used drugs to reduce the injury factors, such as antacids, anticholinergic drugs, H2 receptor antagonists, proglumide, prostaglandin E2 and omeprazole, and also used drugs to protect the gastric mucosa, such as sucralfate, bismuth, carbenoxolone and so on. Thoroughly eradicate Hp, because it is believed that Hp infection is related to this disease at present, so we should actively treat it.
