What is hemolysis

First of all, hemolysis (hemolysis) red blood cell rupture, hemoglobin escape called red blood cell lysis, referred to as hemolysis. It can be caused by a variety of physical and chemical factors and toxins. In vitro, such as hypotonic solution, mechanical strong oscillation, sudden low temperature freezing (- 20 ℃ ～ - 25 ℃) or sudden thawing, excessive acid or alkali, alcohol, ether, soap alkali, choline salt can cause hemolysis.

Secondly, the isotonic solution of human plasma is 0.9% NaCl solution. In the solution of less than 0.45% NaCl, the red blood cells are ruptured due to the expansion of red blood cells due to the infiltration of water, and the hemoglobin is released. In vivo, hemolysis can be caused by the invasion of hemolytic bacteria or some snake venom, antigen antibody reaction (such as blood transfusion incompatible with blood matching), various mechanical damages, internal defects of red blood cells (membrane, enzyme) and some drugs.

Finally, hemolytic bacteria, such as some Streptococcus haemolyticus and Clostridium perfringens, can cause sepsis. Plasmodium destructs red blood cells and some hemolytic snake venoms contain lecithinase, which changes lecithin in plasma or red blood cells into hemolytic lecithin and decomposes erythrocyte membrane. In the case of hemolysis, there will be skin yellowing and sclera yellowing, and some children will have neurological symptoms or fever.
