“Sample size calculation is based on a retrospective analysis of a sample of 159 patients admitted to our ICU during a 3-month period, which fulfilled the study entry criteria. Median time to resolution of circulatory shock, defined as mean systemic blood pressure > 60 mmHg and resolution of clinical signs of shock (capillary refilling time < 3 s, urine output > 0.5 mL/kg/h for at least 4 h, blood lactate < 2 mmol/L), in this sample was 18.5 h (Fig. 1).”

“Sample size calculation is based on a retrospective analysis of a sample of 159 patients admitted to our ICU during a 3-month period, which fulfilled the study entry criteria. Median time to resolution of hemodynamic instability as defined by discontinuation of vasopressors or inotropes in this sample was 18.5 hours (Fig. 1).”
