The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.
Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

Norepinephrine

Doze said the adrenergic system — one of the essential neurochemical systems in the brain — synthesizes and controls the release of the neurotransmitter norepinephrine (also known as noradrenalin).

Norepinephrine works in both the central and peripheral nervous systems. It’s responsible for many critical functions, but in this context, its key functions in the central nervous system include sleep, emotions, learning, and memory.
