REBOOTED - 7. Vasopressors - Part 2

Refractory septic shock requires a systematic approach beyond initial resuscitation, focusing on hemodynamic optimization and identifying underlying triggers. When norepinephrine fails to maintain blood pressure, adding vasopressin at moderate doses and incorporating corticosteroids—specifically hydrocortisone combined with fludrocortisone—improves survival outcomes. Persistent hypotension necessitates ruling out undrained infections, stress cardiomyopathy, or dynamic left ventricular outflow tract (LVOT) obstruction, which is best identified via point-of-care ultrasound. In cases of severe vasoplegia, salvage agents like methylene blue or hydroxycobalamin can effectively scavenge nitric oxide. Successful liberation from the ICU involves weaning norepinephrine before vasopressin and utilizing oral midodrine to facilitate transition to the wards. Proactive de-escalation of vasopressors and early mobilization are critical to preventing iatrogenic complications and ensuring long-term recovery for critically ill patients.
