Correlation of the vasoactive-inotropic score with the length of intensive care unit stay and COVID IgG titers, in multisystem inflammatory syndrome in children: A prospective observational study

Background: Children with multisystem inflammatory syndrome in children (MIS-C) often develop shock and require vasoactive agents. The vasoactive-inotropic score (VIS) is a potential scoring system to assess the amount of vasoactive agent support required. The study was conducted to correlate VIS at 6 and 12 h with the length of intensive care unit (ICU) stay and with COVID immunoglobulin G (IgG) antibody titers in cases of MIS-C with shock. Subjects and Methods: Demographic and clinical details were collected from patients with the diagnosis of MIS-C with shock requiring vasoactive agents. VIS was calculated at 6 and 12 h following initiation of the first inotropic/vasoactive agent. Results: Twenty-nine children admitted with the diagnosis of MIS-C who presented with shock or developed shock during hospital stay were the study population. On performing Spearman's correlation, a positive correlation was observed between COVID IgG titers and VIS at 6 h. There was no significant association between VIS and length of ICU stay. Conclusions: VIS had limited significance in predicting the length of ICU stay and the need for vasoactive agents required.
