What does haemolysis method have

summary

Hemolysis is a very dangerous thing, it is likely to cause death. Once hemolysis occurs, we must take some measures to inhibit this phenomenon, otherwise it will endanger the safety of patients. Now let's talk about the hemolysis method.

What does haemolysis method have

First, hemolysis refers to the process in which the life span of red blood cells is shortened and destroyed. When hemolysis occurs, the ability of bone marrow compensatory proliferation of red blood cells can be increased by 6-8 times, and the proliferation and release of red blood cells can be accelerated. Therefore, if the degree of destruction of red blood cells is light and the compensatory hematopoietic function of bone marrow is enough to compensate for its loss, anemia may not occur, which is called hemolytic disease (compensatory hemolytic disease). For example, the survival time of red blood cells is shortened due to various reasons.

Second: there are many reasons for the excessive destruction of red blood cells, and the diagnosis of patients with hemolytic anemia mainly needs to determine the cause of hemolysis. The number of red blood cells in human body is closely related to the proliferation and differentiation of bone marrow red blood cells. Under physiological conditions, the average survival time of normal red blood cells is 120 days, so there is about 1 / 20 (or 0. 8%) of the red blood cells were destroyed, while the bone marrow proliferated with a corresponding number of red blood cells to maintain the dynamic balance.

Third: intravascular hemolysis, red blood cells in the blood circulation to dissolve the destruction. The number of damaged red blood cells is large and fast. The clinical symptoms are more obvious, manifested as acute hemolysis, often accompanied by hyperhemoglobinemia, hemoglobinuria or hemosiderinuria. It can be seen in hemolysis caused by paroxysmal nocturnal hemoglobinuria, lack of enzymes in red blood cells, incompatibility of blood groups, biological or physical and chemical factors, etc.

matters needing attention

There are many reasons for hemolysis, because hemolysis caused serious damage to the red blood cells in the body, it will cause the death of patients. In order to avoid this phenomenon, patients should regularly go to the hospital to do the relevant examination, early detection can take more effective treatment.
