Correlation of monocyte HLA-DR surface expression and dosage of norepinephrine therapy. There was a statistically significant negative correlation between monocyte HLA-DR surface expression and dosage of norepinephrine [mg/h] to maintain a mean arterial blood pressure ≥ 80 mmHg after 48 h following cardiac arrest (CPR t3: rs = − 0.688; p = 0.005).
