The incidence of maternal hemorrhage and blood transfusion has increased over time. Causes of massive hemorrhage, defined as a transfusion > 10 units of erythrocytes, include abnormal placental insertion, preeclampsia, and placental abruption. ⋯ Autotransfusion, which involves the collection, washing, and filtration of maternal shed blood, avoids many of the complications associated with allogeneic blood transfusion. In this review, we provide an overview of transfusion practices related to the management of obstetric hemorrhage.

ReviewA systematic review of the association between postpartum depression and neuraxial labor analgesia.
Postpartum depression (PPD) is the most common complication after childbirth, affecting 10-15% of women. It is associated with serious long-term consequences for the mother and family. Whether or not neuraxial labor analgesia mitigates the risk is uncertain and controversial. The purpose of this review was to summarize studies investigating the association between neuraxial labor analgesia and the incidence of PPD. ⋯ Our systematic review did not find compelling evidence for an association between PPD and labor analgesia. Studies were heterogenous in nature and had a high risk of bias. Further research controlling for confounding factors is recommended to determine if a relationship exists.

ReviewGastric point-of-care ultrasound (PoCUS) during pregnancy and the postpartum period: a systematic review.
Personalised risk assessment of the likelihood of pulmonary aspiration is recommended for pregnant women undergoing general anaesthesia and gastric point-of-care ultrasound (PoCUS) may help to achieve this. Traditionally, risk assessment is based upon adherence to fasting times, but gastric emptying may vary during pregnancy and surgery often needs to be expedited. We systematically reviewed the evidence for gastric PoCUS up to August 2018 in pregnant and postpartum women to determine whether it can identify and quantify stomach contents, provide aspiration risk assessment via qualitative or quantitative means, and determine how gastric emptying is affected by pregnancy. ⋯ Validated methods to quantify stomach volumes are available, however their usefulness is currently restricted to research. Gastric PoCUS also provides evidence that gastric emptying of ingested food is delayed by term pregnancy, labour and during the early postpartum period. However, the passage of fluids through the stomach appears unaffected throughout the peripartum period.
