Rivers Trial (EGDT) (2001)

Sepsis is a leading cause of mortality in critically ill patients, and at the time of this study, optimal resuscitation strategies were not clearly defined. The study aimed to determine if early, protocol-driven, goal-directed therapy could improve outcomes in patients with severe sepsis and septic shock.

This was a prospective, randomized controlled trial conducted in a single emergency department. Patients with severe sepsis or septic shock were randomized to either standard therapy or early goal-directed therapy (EGDT) targeting central venous pressure, mean arterial pressure, and central venous oxygen saturation. The primary endpoint was in-hospital mortality.

EGDT significantly reduced in-hospital mortality (30.5% vs. 46.5%, p=0.009) and 28-day mortality (33.3% vs. 49.2%, p=0.005) compared to standard therapy. Patients in the EGDT group received more intravenous fluids, red blood cell transfusions, and vasopressors in the first 6 hours. The intervention group also had lower lactate levels and higher central venous oxygen saturation.

Early, aggressive, protocol-driven resuscitation targeting hemodynamic goals in severe sepsis and septic shock can significantly improve patient survival.

This was a single-center study, which may limit generalizability. Subsequent multicenter trials (ARISE, PROMISE, ProCESS) did not replicate the mortality benefit, suggesting the benefit may have been due to overall improved care in the intervention arm rather than specific components of EGDT.
