For neurogenic shock management in acute spinal cord injury, which intervention is most appropriate?

• A. Elevate head of bed 10-15 degrees per hour
• B. Hourly intake and output
• C. Administer atropine
• D. Central venous pressure every 2-4 hours

Answer: (C)

Neurogenic shock after acute spinal cord injury often causes hypotension with bradycardia because the sympathetic nervous system is disrupted and parasympathetic activity predominates. The best initial intervention is administer atropine because it blocks parasympathetic (vagal) effects on the heart, increasing heart rate and improving conduction. This directly counteracts the bradycardia that is compromising cardiac output and tissue perfusion, which is the immediate threat in this scenario. While fluids and vasopressors are also important to raise blood pressure, atropine specifically addresses the slowed heart rate that can worsen hypotension. The other options don’t treat the underlying issue of bradycardia, and invasive monitoring like central venous pressure is not routinely required as an initial step. If bradycardia persists despite atropine, escalation to vasopressors would be considered.
