The fetal NST is a hallmark of antepartum fetal surveillance and a key component of the BioPhysical Profile (BPP). Historically, and still done today, one of the low-risk interventions for rectifying a non-reactive NST has been the maternal administration of glucose/PO challenge. Is this evidence-based? Does maternal hypoglycemia contribute to a nonreactive NST? In this episode, we will review the data spanning a 40-year interval that has sought to answer this question. And what about fetal movement? Does maternal glucose loading increase perception of fetal movement? Let’s go to the data now.
