What is the primary rescue measure for upper gastrointestinal bleeding?

The first rescue measure for upper gastrointestinal bleeding is to replenish blood volume.

When upper gastrointestinal bleeding occurs, with the occurrence of blood loss, the body can lose a large amount of fluid, which is easy to be complicated by hemorrhagic shock. Therefore, venous access should be immediately recommended to ensure rapid blood volume replenishment to prevent shock. Compound sodium chloride injection, balanced salt solution, dextran and hydroxyethyl starch can be given under the guidance of doctors. If necessary, blood transfusion therapy should be given. However, cross matching test should be carried out before transfusion to ensure safety.
