About

The aim of our study was to compare the effects of interscalene block alone and the combination of interscalene block and superficial cervical block on cerebral oxygenation, carotid artery diameter, intraoperative hemodynamics, laboratory parameters, clinical course and postoperative pain in patients undergoing shoulder surgery.

Full description

This study aimed to compare the effects of interscalene block alone and interscalene block combined with superficial cervical plexus block on cerebral oxygenation, carotid artery diameter, intraoperative hemodynamics, and postoperative pain in patients undergoing shoulder surgery.

Peripheral nerve blocks, particularly interscalene block, are commonly used in shoulder surgery due to their superior analgesic efficacy. Cerebral oxygenation was assessed using near-infrared spectroscopy (NIRS), a non-invasive method that reflects regional tissue oxygenation. The effects of both block techniques on bilateral cerebral oxygenation and carotid artery diameter were evaluated using NIRS and ultrasonography, respectively
