This document discusses sepsis management and what has changed. It begins with an introduction to the pathophysiology of sepsis, severe sepsis, and septic shock. It then discusses early goal directed therapy (EGDT) and landmark studies like Rivers 2001 that promoted protocolized resuscitation to targets like central venous pressure, mean arterial pressure, ScvO2, and transfusion thresholds. However, later large trials like ProCESS 2014 found no difference in mortality between EGDT, standard therapy, and usual care. Targets like CVP are not accurate predictors of fluid responsiveness. Studies also found no difference in outcomes between higher and lower blood pressure or hemoglobin transfusion thresholds. There remains uncertainty around optimal fluid type, vas
