BLEEDINGS IN THE HIGH-RISK GROUP OBSTETRIC HOSPITAL

Massive hemorrhage and hemorrhagic shock as main causes of deaths in pregnancy, occupy up to 25% in the structure of mortality rate in obstetrics. In the past decade, the decline in the share of deaths of mothers has occurred due to postpartum bleedings and bleedings in detachment or placenta previa. The aim of the study was to determine the frequency and structure of massive bleedings in a high-risk group obstetric hospital. Methods. A retrospective descriptive cohort study was executed in 2 stages: at the 1st stage - a study of 396 deliveries histories with main nosological forms leading to possible pathological hemorrhage, in the II stage - analysis of 55 cases of massive blood loss. The object of the study was puerperas with placenta previa; puerperas with deliveries complicated by hypotonic bleeding or premature detachment of the placenta; puerperas with the massive blood loss. Duration of the study: from 01.01.2011 to 31.12. 2015. Results. The most frequent nosological form leading to abnormal blood loss is premature placental abruption. The frequency of cases of massive blood loss (more than 1000 ml) is 0.28% of the total number of deliveries and is more common in primigravidae (56.4%), mainly during surgical delivery (88%). Out of all massive bleedings, 45.5% are due to uterine hypotension. Amputation of the uterus was performed in 18.2% of the number of all cases of the massive hemorrhage. Conclusion. The high prevalence rate of the premature detachment of the placenta is explained by the uncontrollability of this pathology, in contrast to hypotonic bleeding in the postpartum period. The organ-preserving management in massive obstetric hemorrhages is not widely used.
