Efficacy of obstetric thromboprophylaxis and long-term risk of recurrence of venous thromboembolism.
To study the efficacy of thromboprophylaxis with low molecular weight heparin (LMWH) in pregnant women with one previous venous thromboembolic event (VTE). Secondary aims were to study the long-term risk of secondary recurrence, bleeding and obstetric complications. ⋯ The relative risk reduction in VTE during thromboprophylaxis was 88%. After pregnancy, the annual long-term risk of recurrence was 1%. The risk was most pronounced in the post-treatment period. There was an increased risk of bleeding complications among women given LMWH, but there was no effect on obstetric complications.

Advanced life support in obstetrics (ALSO) and post-partum hemorrhage: a prospective intervention study in Tanzania.
To evaluate the impact of Advanced Life Support in Obstetrics (ALSO) training on staff performance and the incidences of post-partum hemorrhage (PPH) at a regional hospital in Tanzania. ⋯ A two-day ALSO training course can significantly improve staff performance and reduce the incidence of PPH, at least as evaluated by short-term effects.

ReviewPostpartum hemorrhage--update on problems of definitions and diagnosis.
Maternal mortality due to postpartum hemorrhage (PPH) continues to be one of the most important causes of maternal death worldwide. PPH is a significantly underestimated obstetric problem, primarily because a lack of definition and diagnosis. The 'traditional' definition of primary PPH based on quantification of blood loss has several limitations. ⋯ Proper and timely diagnosis of PPH should above all include accurate estimation of blood loss before vital signs change. Estimation of blood loss by calibrated bags has been shown to be significantly more accurate than visual estimation at vaginal delivery. Careful monitoring of the mother's vital signs, laboratory tests, in particular coagulation testing, and immediate diagnosis of the cause of PPH are important key factors to reduce maternal morbidity and mortality.

ReviewPlacental abruption: epidemiology, risk factors and consequences.
Placental abruption, classically defined as a premature separation of the placenta before delivery, is one of the leading causes of vaginal bleeding in the second half of pregnancy. Approximately 0.4-1% of pregnancies are complicated by placental abruption. The prevalence is lower in the Nordic countries (0.38-0.51%) compared with the USA (0.6-1.0%). ⋯ In developed countries, approximately 10% of all preterm births and 10-20% of all perinatal deaths are caused by placental abruption. In many countries, the rate of placental abruption has been increasing. Although several risk factors are known, the etiopathogenesis of placental abruption is multifactorial and not well understood.
