Treatment of Neurogenic Shock

Initial Management

The first-line treatment for neurogenic shock includes fluid resuscitation followed by vasopressors, with norepinephrine being the preferred agent for refractory hypotension after adequate volume replacement, as recommended by the Intensive Care Medicine guidelines 1, 2
Fluid resuscitation should begin with crystalloid fluid boluses (typically 250-500 mL) and be titrated to maintain adequate tissue perfusion, according to the Intensive Care Medicine guidelines 1, 2
Caution should be taken to avoid excessive fluid administration, as it may lead to pulmonary edema, as warned by the Intensive Care Medicine guidelines 1

Norepinephrine is the recommended first-line vasopressor after adequate fluid resuscitation, targeting both alpha and beta receptors to provide vasoconstriction while supporting cardiac output, as recommended by the Intensive Care Medicine guidelines 1, 2
The target mean arterial pressure (MAP) should be ≥65 mmHg, as recommended by the Intensive Care Medicine guidelines 2
Alternative vasopressors, such as phenylephrine, may be considered in specific cases, as suggested by the European Heart Journal guidelines 3

The target MAP should be ≥65 mmHg to ensure adequate organ perfusion, as recommended by the Intensive Care Medicine guidelines 2
Urine output should be monitored, with a target of >0.5 mL/kg/hr, as recommended by the Intensive Care Medicine guidelines 2
Lactate clearance should be followed as a marker of improved tissue perfusion, as recommended by the Intensive Care Medicine guidelines 2
Signs of improved end-organ perfusion, such as improved mental status and warm extremities, should be monitored, as recommended by the Intensive Care Medicine guidelines 2

Individualized MAP goals may be required based on a patient's baseline blood pressure and comorbidities, as recommended by the Intensive Care Medicine guidelines 2
Ultrasound assessment can help guide fluid management and evaluate cardiac function, as recommended by the Intensive Care Medicine guidelines 2
