Advantages and precautions of autologous blood recovery transfusion

First, let us understand the basic concepts of autologous blood recovery and autologous blood transfusion.

Autologous blood recovery and reinfusion can be unified into one concept, that is, the patient's blood loss (body cavity hemorrhage, intraoperative bleeding, postoperative oozing) is processed by blood recovery equipment: anticoagulation, filtration, centrifugation, washing and other procedures After that, the red blood cells are returned to the patient's own blood transfusion method.

The advantages of autologous blood recovery and transfusion are as follows:

1. It can effectively reduce the patient's dependence on blood bank and blood waste;

2. It can effectively reduce the risk of allogeneic blood transfusion (such as fever, allergy, hemolysis and graft-versus-host reaction); 

3. It can effectively reduce the impact of blood storage injury on patients;

4. It can effectively avoid infection caused by allogeneic blood transfusion.

After the blood is recovered, it can be decided whether to return the blood according to the specific condition of the patient.

Therefore, autologous blood recovery and reinfusion is generally divided into two stages, first recovery and then decide whether to reinfuse.

At present, there is no evidence of serious adverse reactions caused by intraoperative autologous blood transfusion. However, medical staff should still strengthen the monitoring of vital signs during and for a period of time after blood transfusion. It is recommended to use a disposable temperature probe connected to a monitor to monitor the patient's body temperature in real time. If patients have adverse reactions, they should be treated in time and recorded in detail.

And it should be noted that the recovery autologous blood transfusion can only infuse red blood cell components, so when the patient has a large amount of bleeding, the coagulation function of the patient should be monitored at the same time, and the abnormal coagulation function should be corrected in time.
