Obstetrical hemorrhage is the most common cause of maternal mortality worldwide. Together with adequate surgical control and judicious transfusion of blood products, the use of pharmacological agents (e.g., tranexamic acid) and clotting factor concentrates (e.g., fibrinogen concentrates and prothrombin complex concentrates) results in improved hemostasis and decreased bleeding-associated mortality. Guidance in the administration of these agents with the use of viscoelastic testing will likely become standard of care in the near future.

ReviewPostpartum hemorrhage: Blood product management and massive transfusion.
Blood product transfusion capabilities are crucial for appropriate response to postpartum hemorrhage. Novel treatments are continually being sought to improve maternal morbidity and mortality associated with massive hemorrhage.

Postpartum hemorrhage is the leading cause of maternal morbidity and mortality worldwide. The majority of maternal deaths associated with hemorrhage could be preventable. The accurate assessment of blood loss, identification of risk factors and timely recognition of postpartum hemorrhage remain major challenges in obstetrics. It is important to review available modalities for estimation and quantification of peripartum blood loss, the value of risk assessment tools as well as the challenges in early recognition of clinical signs and symptoms of postpartum hemorrhage.

ReviewAn update on the diagnosis and management of bronchopulmonary dysplasia (BPD)-associated pulmonary hypertension.
The past decade of neonatal care has been highlighted by increased survival rates in smaller and more premature infants. Despite reduction in mortality associated with extreme prematurity, long term pulmonary morbidities remain a concern, with growing recognition of the clinical burden attributable to infants with bronchopulmonary dysplasia (BPD)-associated pulmonary hypertension (PH). Recent publications shed light on the critical contributions of maternal placental pathology and compromised intrauterine growth to fetal pulmonary vascular development. ⋯ These recommendations encouraged the use of standardized screening protocols and emphasized the importance of evaluation and treatment of comorbidities when PH is identified. Cardiac catheterization was recommended prior to initiation of therapy for more accurate quantification of pulmonary pressures, clarification of anatomy and guidance in the use of pharmacotherapy. Despite these guidelines, significant practice variation persists and gaps remain with respect to optimal evaluation and management of BPD-associated PH.

ReviewAn update on pulmonary and neurodevelopmental outcomes of bronchopulmonary dysplasia.
Bronchopulmonary dysplasia (BPD) is a common complication of extreme prematurity, and its rate is not improving, despite advances in perinatal intensive care. Children with BPD diagnosed in the neonatal period have higher risks for hospitalizations for respiratory problems over the first few years of life, and they have more asthma in later childhood. ⋯ Survivors with neonatal BPD have more adverse motor function, worse cognitive development and poorer academic progress than those without BPD. Long-term outcomes for children born extremely preterm will improve if the rate of BPD can be substantially reduced.
