ESPB is a newly defined regional anesthesia technique that has been used frequently in recent years. It has been reported to be beneficial in thoracic neuropathic pain as well as in acute pain after thoracic surgery or thoracic traumas [TPVB, widely used in thoracic surgery for the last 2–3 decades, has left its place in other plan blocks that can be easily applied under US guidance, as it can lead to pleural puncture and undesired neural block development [To our knowledge, there are no studies comparing ESPB block applications using different local anesthetic volumes. However, in different studies with different volumes, it was reported that the block level increased up to 9 dermatomes in a study in which 30 ml of local anesthetic was applied [The mechanism of action of the ESPB block, the extent of the local anesthetic and the duration of action are still controversial issues [Pain after thoracotomy is more severe and long-lasting pain due to a wider surgical incision area and trauma caused by the retractors used. For this reason, it is aimed to create a longer and continuous analgesia by applying catheter techniques. ESPB application was used to prevent pain after thoracotomy, and as in our study, single injection ESPB was frequently preferred. Fang et al. [
