Role of echocardiography in reducing shock reversal time in pediatric septic shock: a randomized controlled trial

Abstract

Objective: To evaluate the role of echocardiography in reducing shock reversal time in pediatric septic shock.

Methods: A prospective study conducted in the pediatric intensive care unit of a tertiary care teaching hospital from September 2013 to May 2016. Ninety septic shock patients were randomized in a 1:1 ratio for comparing the serial echocardiography-guided therapy in the study group with the standard therapy in the control group regarding clinical course, timely treatment, and outcomes.

Results: Shock reversal was significantly higher in the study group (89% vs. 67%), with significantly reduced shock reversal time (3.3 vs. 4.5 days). Pediatric intensive care unit stay in the study group was significantly shorter (8±3 vs. 14±10 days). Mortality due to unresolved shock was significantly lower in the study group. Fluid overload was significantly lower in the study group (11% vs. 44%). In the study group, inotropes were used more frequently (89% vs. 67%) and initiated earlier (12[0.5-24] vs. 24[6-72]h) with lower maximum vasopressor inotrope score (120[30-325] vs. 170[80-395]), revealing predominant use of milrinone (62% vs. 22%).

Conclusion: Serial echocardiography provided crucial data for early recognition of septic myocardial dysfunction and hypovolemia that was not apparent on clinical assessment, allowing a timely management and resulting in shock reversal time reduction among children with septic shock.
