Effect of Two Different Plane Blocks on Post-thoracotomy Pain

Thoracotomy is recognized as one of the most painful surgical procedures. This increases the frequency of postoperative pulmonary complications. Erector Spinae Plane Block (ESPB) and Serratus Anterior Plane Block (SAPB) are more superficial, easier to perform, and less likely to have complications. In addition, ESPB and SAPB applications are increasing in patients who underwent thoracotomy and thoracoscopic surgery. In this study, the investigators aimed to evaluate the effect of continuous ESPB and continuous SAPB via US-guidance on post-thoracotomy pain.
