Efficacy of erector spine plane block in two different approaches to lumbar spinal fusion surgery: a retrospective pilot study.

Background: Erector spine plane block (ESPB) has been widely used in spinal surgery, although there are variable data about its efficacy.

Objectives: This study aimed to evaluate the efficacy of ESPB in elective lumbar spinal fusion surgery patients with two different surgical approaches.

Materials And Methods: Retrospectively, 45 elective lumbar transpedicular fusion (TPF) surgery patients undergoing open surgery with different approaches [posterior transforaminal fusion approach (TLIF) or combined posterior and anterior approach (TLIF+ALIF)] were divided into 2 groups: general anesthesia (GA,  = 24) and general anesthesia combined with ESPB (GA + ESPB,  = 21).
