To evaluate the physiological mechanisms, experimental evidence, and clinical efficacy of vasopressin administration in patients with catecholamine-refractory uncontrolled hemorrhagic shock.
Synthesized translational animal models, fluid resuscitation trial data, and recent clinical case reports of uncontrolled blunt and penetrating hemorrhagic shock.
Evaluated hemodynamic responses, autonomic vasoplegia, and vascular reactivity to vasopressin when combined with catecholamines during severe hypovolemic collapse.
Vasopressin infusion restored arterial blood pressure and cardiovascular stability in patients experiencing severe vasoplegia and persistent hypotension refractory to massive fluid resuscitation and catecholamines.
Vasopressin preferentially shunted blood flow away from subdiaphragmatic bleeding sites toward coronary and cerebral circulations, optimizing vital organ perfusion while reducing ongoing hemorrhage.
Low-dose vasopressin (2 to 6 U/h) combined with catecholamines supported hemodynamic bridging to definitive surgery and was associated with full neurological recovery.
