The traditional explanation and assumed pathophysiology of HELLP syndrome stated that it was a late manifestation/further progress of preeclampsia with severe features. But can HELLP present clinically without hypertension? What about without proteinuria? If a patient has lab criteria of HELLP alone, without hypertension, does she still require magnesium sulfate? In this episode, we will summarize data from 3 sources (ACOG practice bulletin on thrombocytopenia, ACOG practice bulletin on gestational hypertension and preeeclampsia, CMQCC hypertension bundle), and answer these questions and more.
