Cause of hemolytic reaction?

summary

Hemolytic reaction is a serious disease. For example, if two different blood groups are put together, hemolytic reaction will occur. Of course, the cause of hemolytic reaction is not only this. Let's talk about the causes of hemolytic reaction.

Cause of hemolytic reaction?

First, the causes of hemolytic reaction include transfusion of heterotypic blood. At this time, blood transfusion should be stopped immediately and the remaining blood should be retained. Blood samples were collected, blood group identification and cross matching test were repeated, patients were comforted, and sodium bicarbonate was given orally or intravenously to alkalize urine to prevent or reduce hemoglobin crystal obstruction of renal tubules.

Second, another reason is that red blood cells have been destroyed and hemolyzed before blood transfusion, such as blood stored for a long time and improper storage temperature (the refrigerator of blood bank should be kept at 4 ℃). Blood concussion, hypertonic or hypotonic solution, drugs affecting pH, bacterial contamination of blood, etc.

Third, the best reason is that Rh factor is not suitable. Close both sides of the waist, and apply hot water bag on both sides of the kidney area, prevent renal vasospasm, protect the kidney, closely observe vital signs and urine volume, and record, carefully do blood type identification and cross matching test, carefully check before blood transfusion, and eliminate errors. Strictly implement the rules of blood preservation, and do not use deteriorated blood.

matters needing attention

After we know the causes of hemolytic reaction, we must avoid this situation at ordinary times. If we don't pay attention, hemolytic reaction may cause life-threatening, which will bring more trouble and pain to patients.
