Significance of autologous blood transfusion to modern obstetrics

Looking at the relevant data, it can be found that the top causes of maternal death in my country for many years are all related to massive bleeding during childbirth.

Obstetric haemorrhages tend to occur rapidly, pushing the mother to the brink of danger in a short period of time. This is because the blood volume of the mother may reach thousands of milliliters in one minute. And it is very difficult to stop the bleeding.

Therefore, in the event of massive hemorrhage during childbirth, massive blood transfusion is required immediately to save the life of the mother.

For many years, allogeneic blood transfusion accounts for a larger proportion of obstetric hemorrhage. However, we still have to clearly recognize the limitations of allogeneic blood transfusion.

For example, the lack of allogeneic blood supply, the possibility of infectious diseases in the blood, the activity of the immune system related to blood transfusion, the damage of blood value during the storage of blood transfusion (even if the blood bank is cryopreserved, the red blood cells will rapidly age and rupture outside the body), etc. The problem.

And there are also solid studies showing that transfusion of large amounts of bank blood after maternal haemorrhage may prolong hospital stays and reduce survival.

Therefore, it is recommended to actively carry out the project of autologous blood recovery and transfusion in pregnant women, and relevant departments should strictly grasp the indications of intraoperative blood transfusion to complete a reasonable and safer blood transfusion process.

Some reports also mentioned that the use of autologous blood transfusion for high-risk bleeding cesarean section women can not only save lives in time, but also significantly reduce the amount of allogeneic blood transfusion, save blood resources, and improve the prognosis of patients.
