A 24-year-old man falls from height. He has BP 82/50 mmHg, heart rate 46/min, warm dry skin, and flaccid paralysis with absent reflexes below the nipple line. Two litres of crystalloid produce no rise in blood pressure. What is the next best step?

  • A Continue aggressive crystalloid boluses
  • B Start norepinephrine infusion
  • C Give intravenous atropine alone
  • D Start epinephrine infusion
Correct answer: B. Start norepinephrine infusion

Explanation

The combination of hypotension with paradoxical bradycardia, warm skin, and a sensory-motor level points to neurogenic shock from cervical or upper thoracic cord injury. Loss of sympathetic vasomotor tone requires a vasopressor with alpha activity; norepinephrine restores vascular tone and supports chronotropy. Atropine treats isolated bradycardia but does not correct the peripheral vasodilation driving the hypotension.
