Important changes affect all aspects of care covered in the
2008 guidelines. Notable examples include the addition of
systolic BP in the definition of pregnancy hypertension,
revised HDP classification, new information on
prevention, more direction with respect to timing of
delivery in women with any HDP, information about
magnesium sulphate for fetal neuroprotection at < 32
weeks, a new gestational age cut-off (≤ 34+6 instead of
≤ 33+6 weeks) for administration of steroids, and a
section on knowledge translation with links to useful
tools for women and practitioners.
