Thoracic epidural anesthesia (TEA) is a widely used technique for analgesia after thoracic surgery.However, it has several adverse effects. The erector spinae plane block (ESPB) is a relatively simple and safe technique. This study aimed to compare the analgesic efficacy of ESPB and TEA.Patients who underwent video-assisted thoracic surgery (VATS) were assigned to either the ESPB or TEA group. Numerical Rating Scale (NRS) pain scores were recorded at rest and during movement in both groups until 2 days after surgery. Adverse effects were also recorded.Although the average NRS score in the ESPB group was less than 2 at rest and less than 4 during movement, these scores were significantly higher than those in the TEA group. There were significantly fewer patients with hypotension in the ESPB group. The ESPB is associated with low NRS scores and provides effective pain relief in patients undergoing VATS. The ESPB has the advantage of conferring a lower incidence of adverse effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
