Q

Describe the concept of complete spinal cord injury and differentiate between the concepts of spinal shock and neurogenic hypotension.

A

Spinal shock is temporary concussion-like insult to the spinal cord that causes effects below the level of the injury

  • Temporary loss of movement and feeling

neurogenic hypotension (Neurogenic shock) follows the spinal shock

  • loss of signal nerve impulses to the arteries which causes arteries to relax and dilate leading to hypovolemia
