Coagulation Tests and Volume of Blood Loss in Patients with Premature Placental Abruption

Abstract

Introduction. Placental abruption continues to be one of the leading causes of bleeding during pregnancy and delivery, posing a direct threat to the health and life of both mother and fetus, making a significant contribution to the structure of maternal and neonatal morbidity and mortality. The study of predictors and prediction of the severity of the consequences of this complication is one of the areas of scientific research.The purpose of the study is to expand the possibilities of predicting massive bleeding, which is a consequence of premature placental abruption, based on the analysis of prenatal laboratory parameters of the hemostasis system as a universal tool for optimizing the choice of treatment tactics.Material and methods. A retrospective assessment of the relationship between the volume of bleeding and prenatal laboratory parameters of the hemostasis system was carried out in 46 patients with premature detachment of the placenta delivered by caesarean section in Sverdlovsk Regional Children Clinical Hospital, Ekaterinburg in 2020 using the methods of statistical analysis of quantitative indicators.Results and discussion. When comparing the volume of blood loss with prenatal indicators of hemostasis, prognostic significance was revealed and paired linear regression equations were constructed for the following parameters: platelet level, plateletcrit, prothrombin time, Quick prothrombin time, activated partial thromboplastin time. And no relationship was found between the volume of blood loss and MPV (p = 0.231), PDW (p = 0.121), P-LCR (p = 0.205), thrombin time (p = 0.79), fibrinogen value (p = 0.07).Conclusion. The results of the study can be used in building a decision-making algorithm and medical tactics of a multidisciplinary team during care for a patient with premature placental abruption, however, further research is required in this direction to build a universal formula for predicting bleeding volume in placental abruption.
