Background: The role of vasoactive medications in septic shock is well-defined, but the appropriate time of initiation of these medications in reference to fluid boluses is not clear. We planned to study prospectively the practices and outcome of initiation of vasoactive infusions with respect to resuscitation fluids boluses in pediatric septic shock.
Patients and methods: Children aged 1 month to 18 years diagnosed with septic shock were enrolled to receive fluid resuscitation boluses along with vasoactive drugs. The primary outcome was to look at various practices of the initiation of vasoactive infusions; accordingly, patients were categorized into three groups: N1 received vasoactive infusions after completion of the first bolus (20 mL/kg), N2 after the second (40 mL/kg), and N3 after the third fluid (60 mL/kg) bolus. Secondary outcomes were to compare the time taken, amount of fluid required to achieve hemodynamic stability, total fluid required, and complications in the first 24 hours of treatment and mortality.
Results: Hundred children were enrolled and grouped into N1, N2, and N3 with 46, 10, and 44 patients, respectively. The volume of fluid required to achieve the resolution of shock in N1 (40 ± 10 mL/kg) was significantly less than in N2 (70 ± 10 mL/kg) and N3 (70 ± 20 mL/kg); p = 0.02. The time taken to achieve hemodynamic stability was significantly less in N1 (115 ± 45 minutes) than in N2 (196 ± 32 minutes) and N3 (212 ± 44 minutes); p = 0.02. The volume of intravenous fluid required in the first 24 hours (p = 0.02) and complications were lower in the N1 group (p = 0.04). No statistical difference in mortality was seen.
Conclusion: Early initiation of vasoactive infusions (after the first bolus) resulted in less total fluid volume, lesser time to achieve hemodynamic stability, less fluid boluses, less length of stay in the pediatric intensive care unit, and lesser complications in the first 24 hours.
Highlight: Early initiation of vasoactive infusions—after completion of the first fluid bolus resulted in less need for further fluid boluses, lesser time for shock resolution, lesser fluid overload, and less PICU stay—in pediatric septic shock.
