Hemorrhagic shock requires urgent replenishment of blood volume, first of all, intravenous access needs to be opened and saline or some other colloidal solution needs to be infused. If the blood pressure is quickly restored to a stable and normal level after the infusion, it means that the bleeding situation has been basically controlled. If the erythrocyte pressure product is relatively high, above 30%, there is no need to apply for transfusion of erythrocyte suspension, otherwise blood transfusion should be chosen as much as possible to maintain the erythrocyte pressure product at about 30%. The central venous pressure should also be monitored in a timely manner when rehydrating. Excessive rehydration is likely to cause an increase in venous pressure and increase the burden on the heart. The cause of the disease should be treated as soon as possible while rehydrating, and the bleeding should be stopped as soon as possible. After the blood pressure is restored to a stable level, the hemostatic treatment should be carried out fundamentally. If the hemostatic effect of conservative medical treatment is not good, and the blood flow is too large to be controlled, you should try to choose the surgical method to stop the bleeding, and replenishing the blood volume as well as finding the cause is an important step in the treatment of hemorrhagic shock.
