Episode 3.8 Measuring Amniotic Fluid, Magnesium, and Treating Chronic Hypertension

In this episode, we discuss the evidence for the best ways to measure amniotic fluid and diagnose oligohydramnios and polyhydramnios. We also discuss a new study about when to stop magnesium after delivery of patients with preeclampsia and then we discuss the CHAP study that has changed our management of chronic hypertensive patients while pregnant.
