The Effect of Regional Anesthesia Techniques on Brain Tissue Oxygenation in Thoracic Surgery

The Effect of Regional Anesthesia Techniques on Brain Tissue Oxygenation in Thoracic Surgery Operations Where Single Lung Ventilation is Applied

Today, it is preferred that the lung with pathology for thorax surgery is not under ventilation during operation in terms of reliability and ease of operation.

For this reason, the anesthesia approach is characteristic and it is ensured that the single lung is not ventilated during the operation by means of specially manufactured intubation tubes. This application can disrupt tissue oxygenation due to both Operation position and single lung ventilation.

Thoracic epidural analgesia, which is applied as the gold standard of Thoracic Surgery, is applied prior to the operation and is provided to assist in postoperative analgesia.

The aim of this study was to investigate the effect of thoracic epidural analgesia method on brain tissue oxygenation in patients with single lung ventilation.
