About this trial
The goal of this clinical trial is to investigate whether methylene blue injection can safely and effectively improve the survival rate of patients with severe septic shock, shorten the duration of norepinephrine use, reduce the dosage of vasopressors, promptly correct hemodynamics, and improve tissue perfusion and organ function impairment.
Eligibility criteria

Diagnosed with septic shock and started on norepinephrine within 24 hours.
Requires a norepinephrine dose of ≥ 0.1 μg/kg/min to maintain a MAP of ≥ 65 mmHg.
Disqualifiers
Pregnant or breastfeeding women.
