Shock persists after initial fluid bolus(es)?
โโ YES โ Fluid-Refractory Septic Shock
โธ Continue fluid boluses (10-20 mL/kg) up to 40-60 mL/kg total in first hour (in ICU-access settings)
โธ Start vasoactive infusion via central line (or peripheral/IO if central not yet available)
โโ Cold shock (poor perfusion, cool extremities, delayed capillary refill) โ Epinephrine 0.05-2 mcg/kg/min
โโ Warm shock (flushed, warm extremities, bounding pulses) โ Norepinephrine 0.05-2 mcg/kg/min
โธ If shock persists โ escalate vasoactive dose, add second agent
โโ Catecholamine-resistant shock โ consider hydrocortisone (if adrenal insufficiency), add vasopressin, consider ECPR/ECMO
Continuously reassess: titrate fluids/vasoactives to normalize perfusion, BP, lactate clearance
