Abstract
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, n = 24) and general anesthesia combined with ESPB (GA + ESPB, n = 21). The primary outcome was to analyze the efficacy of ESPB in two different surgical approaches in terms of pain intensity in the first 48 h. Secondary: Fentanyl-free patients and opioid consumption in the first 24 h postoperatively. Comparative analysis was performed (SPSS ® v. 28.0) ( p < 0.05). RESULTS: Out of 45 patients (27 female), 21 received GA + ESPB and 24 received GA. The average age was 60.3 ± 14.3 years. Chronic back pain before the operation was registered in 56% of patients. ESPB was performed in 17 TLIF and in 4 TLIF+ALIF patients. ESPB significantly reduced pain intensity at rest in both surgical approaches 48 h after surgery ( p < 0.05). The need for postoperative fentanyl infusion was significantly lower in the group treated with GA + ESPB in both surgical approaches than in those who only received GA (29% vs. 77% in TLIF and 0% vs. 80% in TLIF+ALIF); p = 0.01 and p = 0.004. Additionally, we observed that ESPB provides a good analgesic effect for up to 6.8 ± 3.2 h in the TLIF and 8.9 ± 7.6 h in the TLIF+ALIF approaches. Consequently, ESPB reduced the initiation of the fentanyl compared to GA alone, with a mean difference of 3.2 ± 4.2 h in the TLIF subgroup ( p = 0.045) and 6.7 ± 5.3 h in TLIF +ALIF ( p = 0.028). Only in the TLIF+ALIF approach, ESPB reduced the total fentanyl consumption compared to those with GA (1.43 ± 0.45 mg/24 h vs. 0.93 ± 0.68 mg/24 h; p = 0.015). CONCLUSION: ESPB significantly reduced pain at rest after surgery, the number of patients requiring immediate postoperative fentanyl analgesia, and total fentanyl consumption in both surgical approaches, particularly in TLIF+ALIF. However, the application of ESPB does not always provide completely sufficient analgesia.
