Sympatholytic Effects of High Thoracic Erector Spinae Plane Block: Changes in Optic Nerve Sheath Diameter
Sponsor: Pamukkale University
Summary
The thoracic erector spinae plane (ESP) block is suggested to potentially affect the stellate ganglion, a key component of the sympathetic nervous system, thereby influencing autonomic functions. Changes in optic nerve sheath diameter (ONSD) are used as indicators of intracranial pressure changes. This study aims to investigate the effects of the ESP block on ONSD, providing insights into its impact on the stellate ganglion and enhancing the understanding of the ESP block's safety and efficacy.

thoracic erector spinae plane (ESP) block
The thoracic erector spinae plane (ESP) block is a regional anesthesia technique used for pain management in complex regional pain syndrome. This procedure involves injecting 20 ml of 0.25% bupivacaine into the deep layers of the erector spinae muscles. The patient is positioned appropriately, and the injection site is identified using anatomical landmarks and ultrasound guidance, at the T2 level. A needle is then inserted perpendicularly until it contacts the transverse process, at which point the local anesthetic is administered. The primary objective is to provide significant pain relief.
