Effects of erector spinae plane block on perioperative hemodynamic stability, blood loss, and postoperative pain in transforaminal lumbar interbody fusion

Erector spinae plane block (ESPB) is a promising technique for enhancing recovery and minimizing opioid use, but its impact on intraoperative blood pressure variability (IBPV) and perioperative outcomes in transforaminal lumbar interbody fusion (TLIF) remains unclear. This retrospective study analyzed 60 TLIF patients (30 with ESPB, 30 without) from January 2021 to June 2023. ESPB significantly reduced IBPV, as evidenced by lower mean arterial pressure differences and coefficients of variation. The ESPB group also experienced reduced intraoperative blood loss, postoperative pain, and faster nutritional recovery. While trends toward early mobility and decreased morphine consumption were observed, ESPB did not introduce additional complications. These findings suggest that ESPB is an effective strategy to optimize perioperative outcomes and enhance recovery in TLIF procedures.
