Echocardiography-guided hemodynamic management of severe sepsis and septic shock in adults: a randomized controlled trial

Background: Echocardiography (ECHO) is used to guide septic shock resuscitation, but without evidence for efficacy. Therefore, we compared the outcome of early goal-directed therapy (EGDT) and ECHO-guided management of hemodynamics in severe sepsis and septic shock. Methodology: This was a single center, randomized controlled trial conducted on 100 adult patients with severe sepsis or septic shock. Patients were assessed and treated with either EGDT protocol (Group I - EGDT group) or ECHO-guided resuscitation protocol (Group II - ECHO group). Results: Only 87 patients (45 in Group I and 42 in Group II) were analyzed. There was a significant increase of mean norepinephrine and dobutamine use and a significant decrease in total fluids needed in the first 24 h, time to normalization, time to weaning of vasopressors, total mechanical ventilation (MV) days, MV free days and ICU and hospital stay in ECHO group. At 30 days, the mortality rate in EGDT group was 35.6% which was significantly higher compared to 14.3% in the ECHO group. At 90 days, the overall mortality was significantly higher in EGDT group compared to ECHO group (40.0% vs 16.7% respectively). Hazardous ratio of mortality was 1.630 [95% confidence interval (CI): 1.123 - 2.366] and 1.653 (95% CI: 1.137 - 2.404) at 30 and 90 days respectively in EGDT group compared to ECHO group. Conclusions: In severe sepsis and septic shock, ECHO-guided management of hemodynamics resulted in a decrease in mortality, lower total fluid intake, higher vasopressor and inotrope support, earlier weaning of vasopressors; and reduced mechanical ventilation days, as well as ICU and hospital stay.
