RESUMEN
Background: Peripartum haemorrhage (PPH) is a potentially life-threatening complication. Although still rare, the incidence of peripartal haemorrhage is rising in industrialised countries and refractory bleeding remains among the leading causes of death in the peripartal period. Summary: The interdisciplinary German, Austrian, and Swiss guideline on "Peripartum Haemorrhage: Diagnostics and Therapies" has reviewed the evidence for the diagnostics and medical, angiographic, haemostatic, and surgical treatment and published an update in September 2022 . This article reviews the updated recommendations regarding the early diagnosis and haemostatic treatment of PPH. Keystones of the guideline recommendations are the early diagnosis of the bleeding by measuring blood loss using calibrated collector bags, the development of a multidisciplinary treatment algorithm adapted to the severity of bleeding, and the given infrastructural conditions of each obstetric unit, the early and escalating use of uterotonics, the therapeutic, instead of preventative, use of tranexamic acid, the early diagnostics of progressive deficiencies of coagulation factors or platelets to facilitate a tailored and guided haemostatic treatment with coagulation factors, platelets as well as packed red blood cells and fresh frozen plasma when a massive transfusion is required. Key Messages: Essential for the effective and safe treatment of PPH is the timely diagnosis. The diagnosis of PPH requires the measurement rather than estimation of blood loss. Successful treatment of PPH consists of a multidisciplinary approach involving surgical and haemostatic treatments to stop the bleeding. Haemostatic treatment of PPH starts early after diagnosis and combines tranexamic acid, an initially ratio-driven transfusion with RBC:plasma:PC = 4:4:1 (when using pooled or apheresis PC) and finally a goal-directed substitution with coagulation factor concentrates for proven deficiencies. Early monitoring of coagulation either by standard parameters or viscoelastic methods facilitates goal-directed haemostatic treatment.
RESUMEN
Even nowadays and at specialized centers, one of the leading causes of death is exsanguination. Trauma-induced coagulopathy (TIC) occuring with massive blood loss primarily results from loss of coagualtion factors and platelets and is aggravated by hemodilution. In addition, hyperfibrinolysis, hypothermia, acidosis and hypocalcaemia also contribute to the development of severe haemostatic derangement. During the past few years new insights into the pathophysiology of TIC and the widespread use of viscoelastic coagulation monitoring provoked the development of alternative treatment concepts. As for the previously recommended standard therapy using fresh frozen plasma and platelet concentrates also for alternative strategies no data from large prospective randomized studies are available until now, however, the evidence is growing favoring the use of coagulation factor concentrates guided by viscoelastic measurements.
