ReviewPoint-of-care coagulation testing for postpartum haemorrhage.
The use of viscoelastic haemostatic assays (VHAs) to guide blood product replacement during postpartum haemorrhage is expanding. Rotem and TEG devices can be used to detect and treat clinically significant hypofibrinogenaemia, although evidence to support the role of VHAs for guiding fresh frozen plasma and platelet transfusion is less clear. If Rotem/TEG traces are normal, clinicians should investigate for another cause of bleeding, and haemostatic support is not required. ⋯ There is a wide consensus that fibrinogen replacement is needed if the Fibtem A5 is <12 mm and if there is ongoing bleeding. Guidelines recommend against using VHAs to guide tranexamic acid infusion, and this drug should be given as soon as bleeding is recognised, irrespective of the Rotem/TEG traces. The cost-effectiveness of VHAs during postpartum haemorrhage needs to be addressed.

ReviewRisk assessment tools to predict postpartum hemorrhage.
Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity and mortality, and accurate risk assessments may allow providers to anticipate and prevent serious hemorrhage-related adverse events. Multiple category-based tools have been developed by national societies through expert consensus, and these tools assign low, medium, or high risk of hemorrhage based on a review of each patient's risk factors. ⋯ However, there are no published studies demonstrating external validation or successful clinical use of such models. Future work should include refinement of these models, study of best practices for implementation, and ultimately linkage of prediction to improved patient outcomes.

ReviewProcedural techniques to control postpartum hemorrhage.
Postpartum hemorrhage can occur unexpectedly and with high dynamics. The mother's life often depends on quick action and good communication within an interdisciplinary team. Knowledge of each other's therapeutic options plays a major role. ⋯ From these two points of view, we discuss here different uterus-preserving and uterus-removing techniques. We describe in detail the advantages and disadvantages of each procedure. Because most therapeutic options are based on small case series and uncontrolled studies, local circumstances and physician experience are critical in setting internal standards.

ReviewOptimizing systems to manage postpartum hemorrhage.
Systems to optimize the management of postpartum hemorrhage must ensure timely diagnosis, rapid hemodynamic and hemostatic resuscitation, and prompt interventions to control the source of bleeding. None of these objectives can be effectively completed by a single clinician, and the management of postpartum hemorrhage requires a carefully coordinated interprofessional team. This article reviews systems designed to standardize hemorrhage diagnosis and response.
