Abstract

Background: Microcirculatory dysfunction appears early in the pathophysiology of septic shock and correlates with the severity of organ failure as well as mortality in the ICU. Tissue oxygen saturation (StO2) measured by near-infrared spectroscopy (NIRS) is one of the indicators that can be used to assess tissue oxygenation. Objectives: To determine the correlation of StO2 with lactate, pSOFA score at the time of shock (T0), after 6 hours (T6), and after 24 hours (T24) of treatment. Subjects and methods: A longitudinal observational study, 35 pediatric patients with septic shock from 11/2021 to 9/2022 inpatient treatment at City Children's Hospital. Results: StO2 at after 6 hours treatment was slightly negatively correlated with lactate (r = -0.368; p = 0.030). StO2 was negatively correlated with pSOFA score at all time points of the survey. The negative correlation between StO2 and lactate, the pSOFA score did not change when controlling confounding factors. Conclusion: Monitoring StO2 in combination with other macrovascular and microcirculatory hemodynamic parameters helps to detect microcirculatory disorders. Monitoring of StO2 at the time of shock, after 6 hours of treatment has the potential to support the prognosis of patients with multi-organ dysfunction.
