Overall, addition of FLU in children with SIRS was not associated with decreased vasopressor duration or vasopressor score. However, HC + FLU was associated with shorter duration of NE support in the septic subgroup. Hypokalemia was a frequent adverse finding with HC + FLU (p = 0.05). Use of FLU should be considered in further studies evaluating the role of steroids in refractory pediatric septic shock.
