Clinical research progress related to massive blood transfusion in obstetrics

In obstetrics, obstetric mass transfusion requires extensive coordination amongst obstetric, anaesthesia and blood bank teams. In the clinical process, obstetric haemorrhage is one of the most common causes of obstetric morbidity and mortality. Intraoperative and postpartum haemorrhage will pose a certain threat to the puerpera and bring great challenges to clinicians. Therefore, timely identification of risk factors for obstetric massive transfusion can bring more opportunities for treatment and improve the survival rate of puerpera. Blood transfusion is still the most important treatment in the rescue of obstetric haemorrhage, but careless blood transfusion will bring serious consequences. Massive transfusion protocols (MTP) is a predictive blood transfusion protocol, which is used to correct the coagulation dysfunction by adding plasma, clotting factors and platelets, even when red blood cells are added in response to massive blood loss in obstetrics. MTP not only includes the amount of input, but also is an emergency linkage mechanism. Reasonable allocation of blood components and clear management rules for various matters in blood transfusion have been formulated to make the supply of blood components more effective. In the process of the rescue, staff should follow the specification, standard blood transfusion strategy, timely grasp the obstetric numerous transfusions start time, quick to adopt appropriate proportion of rapid blood transfusion, deal with a large number of blood transfusions of critical condition, recovery quickly promote maternal blood volume. This is the important link in the process of treatment, which is of extremely important significance to improve the success rate of rescue.
