Perioperative Sympathetic Blockade: Mechanisms and Clinical Advances in Sensory Processing Modulation - A Narrative...

Area of Science:

• Neuroscience
• Surgical Medicine
• Pain Management

Background:

• Surgical trauma can induce abnormal sensory processing, impacting perioperative pathophysiology.
• The sympathetic nervous system (SNS) plays a key role in regulating sensory input and physiological responses during the perioperative period.

Purpose of the Study:

• To re-examine the mechanism of sympathetic nerve blockade.
• To elucidate the SNS's role in sensory processing and perioperative adaptations.
• To explore the therapeutic potential of nerve block techniques.

Main Methods:

• Review of existing literature on sympathetic nerve blockade mechanisms.
• Analysis of SNS regulation of sensory input via sympathetic-sensory coupling, neuro-immune-endocrine interactions, and microcirculatory adjustments.
• Examination of stellate ganglion block and lumbar sympathetic block applications.

Main Results:

• Sympathetic nerve blockade may reset maladaptive sensory signaling pathways through multi-system interactions.
• SNS regulates sensory input through layered processes.
• Nerve block techniques yield broad therapeutic outcomes, including pain relief, stress modulation, and organ protection.

Conclusions:

• Sympathetic nerve blockade is a crucial intervention for managing perioperative sensory dysfunction.
• Future advances may involve precision-oriented sympathetic interventions using neural circuit mapping, biomarkers, and AI.
• Understanding SNS-mediated sensory processing is key to optimizing surgical recovery.
