For the anesthetic management of patients with CIPA, the control of body temperature, analgesia, and treatment of dysfunction of the postganglionic sympathetic fibers are important.
Without this receptor, primary afferent neurons and postganglionic sympathetic fibers, which are dependent on NGF for growth and survival, are lost, and their loss induces both autonomic disturbance and loss of pain sensation [1, 2].
These neurons provide excitatory output to preganglionic neurons located in the intermediolateral cell column of the spinal cord that innervate several target organs through postganglionic sympathetic fibers. Excitatory drive can be intrinsically generated, chemically mediated, or differentially controlled via the cortical, limbic, and midbrain regions of the central nervous system.
Postganglionic sympathetic fibers travel along the external carotid artery to the superficial temporal artery and the transverse facial artery and terminate in the sweat glands.
