Patient with spinal cord injury may experience multiple long-term complications due to the loss of nerve function in various parts of their body. Wagner R(1), Jagoda A. Radiographics. Central cord syndrome can often be missed in the ED, as the imaging in these patients is often unremarkable, and their sensory deficits can be patchy. | Bradycardia may be treated with atropine or pacing, while hemodynamic therapy is supportive with fluids and vasopressors to help increase perfusion.
