Reduced effective blood volume

Hemorrhagic peripheral circulation failure is a clinical symptom of gastrointestinal bleeding, which is manifested by a large amount of upper gastrointestinal bleeding leading to acute peripheral circulation failure. The amount of blood loss is large, the bleeding is not continuous or the treatment is not timely can cause the body's tissue blood perfusion to be reduced and the cells to be hypoxic. In addition, due to hypoxia, metabolic acidosis and accumulation of metabolites, the surrounding blood vessels are dilated and the capillaries are extensively damaged. As a result, a large amount of bodily fluids are stagnated in the abdominal bones and surrounding tissues, which effectively reduces the effective blood volume and seriously affects the heart The blood supply to the brain, kidneys, and kidneys finally formed an irreversible shock, leading to death.
