The article presents an analysis of the modern approach to the treatment of acute obstetric hemorrhage. Some features of the preparation of leukodepleted and pathogen-reduced blood components are shown and indications for use in severe obstetric blood loss are determined. It has been shown that the pathogen reduction of blood components leads to a decrease the level of coagulation factors (coagulation factor VIII, fibrinogen in fresh frozen plasma) by 20-30 %, the activity and number of platelets by 15-20 % in platelet concentrate, does not affect the morphological usefulness of platelets. A "package" of blood components for the provision of emergency transfusion therapy for obstetric bleeding has been calculated. The need for a given quantity of blood components was determined – 2.3 "packages" per 1000 births. The proposed "emergency obstetric care packages" and the organization of their centralized delivery to medical healthcare organizations ensure a high degree of readiness of the blood service to comply with the "golden hour" rule for treating acute severe obstetric hemorrhage and minimize post-transfusion reactions and complications when using them. Pathogen-reduced blood components are expensive. Therefore, their use in clinical practice is indicated for the decreed contingents of recipients: for organ and tissue transplantation, in neonatology, oncohematology and for recipients with “multiple transfusions of blood, its components”, in cardiac surgery and obstetric practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
