Recent evidence and guidance for the ideal timing of early dating ultrasounds has been adjusted, with the recommendation that this scan be performed no earlier than 8 weeks + 0 days gestation. This recommendation aligns with recently published guidelines for induction of labour from the Society of Obstetrician and Gynegcologists. Likewise, the provincial consensus guidelines for "best estimate" of gestational age have been updated to reflect these recommendations.
NS Consensus Guideline for the Assessment of Gestational Age
Please review the memo from the IWK Fetal Assessment and Treatment Center requesting that all patients being referred for an early pregnancy review, from outside HRM, first have an early dating ultrasound conducted locally between 8-12 weeks gestation.
