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.

Heart rate - Increases or decreases as arousal increases or decreases

Drive Theory essentially predicts that performance increases in a linear fashion as arousal increases. More precisely, drive theory predicts that performance is a function of the interaction between habit and drive (arousal).

Commonly used measures of AROUSAL
Brain activity - Changes are thought to reflect changes in arousal; alpha activity is thought to reflext low arousal (relaxation), whereas beta activity is thought to reflect higher levels of arousal

Heart rate - Increases or decreases as arousal increases or decreases

Cortisol - A stress hormone released during an encounter with a stressor or challenge (physical or psychological)
