The Society for Maternal-Fetal Medicine (SMFM) has issued recommendations on the management of bleeding in the late preterm period. The document is intended to provide guidance on management of late preterm (34 0/7 to 36 6/7 weeks of gestation) vaginal bleeding. Among the recommendations:
- SMFM recommends delivery at 36-37 6/7 weeks of gestation for stable women with placenta previa without bleeding or other obstetric complications, such as preeclampsia or fetal growth restriction.
- SMFM does not recommend routine cervical length screening for women with placenta previa in the late preterm period due to lack of data on an appropriate management strategy.
- SMFM recommended a planned delivery between 34 and 37 weeks of gestation for stable women with placenta accrete.
- SMFM recommends that in women with active hemorrhage in the late preterm period, delivery should not be delayed for the purpose of administering antenatal corticosteroids (ACS).
- SMFM recommends that fetal lung maturity testing should not be used to guide management in the late preterm period when an indication for delivery is present.
- SMFM recommends that ACS should be administered to women who are eligible and are managed expectantly if delivery is likely without 7 days, the gestational age is between 34 0/7 and 36 6/7 weeks of gestation, and if ACS has not previously been administered.
