Guanethidine-induced destruction of sympathetic postganglionic neurons in neonatal rats leads to transneuronal degeneration of the sympathetic preganglionic neurons. Using this model, we have been able to show a approximately 35% decrease in [3H]substance P ([3H]SP) binding in the intermediolateral cell column--suggesting that sympathetic preganglionic neurons possess substance P receptors. Our results show that [3H]substance P binding in the intermediolateral cell column is dependent on the integrity of sympathetic postganglionic neurons.

Substance P is an important element in pain perception. The sensory function of substance P is thought to be related to the transmission of pain information into the central nervous system. Substance P coexists with the excitatory neurotransmitter glutamate in primary afferents that respond to painful stimulation.[16] Substance P has been associated with the regulation of mood disorders, anxiety, stress,[17] reinforcement,[18] neurogenesis,[19] respiratory rhythm,[20] neurotoxicity, nausea and emesis,[21] pain, and nociception.[22] Substance P and other sensory neuropeptides can be released from the peripheral terminals of sensory nerve fibers in the skin, muscle, and joints. It is proposed that this release is involved in neurogenic inflammation, which is a local inflammatory response to certain types of infection or injury.[23] The regulatory function of SP also involves the regulation of its high-affinity receptor, NK-1. Substance P receptor antagonists may have important therapeutic applications in the treatment of a variety of stress-related illnesses, in addition to their potential as analgesics.

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.
