Background

The paraspinal interfascial plane block is a regional anesthesia technique that may improve pain control after posterior spine surgery, but its impact on outcomes remains underreported in large cohorts.

Purpose

To evaluate the association between paraspinal interfascial plane (paraspinal interfascial plane) block use and postoperative outcomes and resource utilization in posterior lumbar spine surgery.

Methods

We retrospectively reviewed 327 age-matched adult patients who underwent posterior lumbar surgery between October 2020 and June 2024.

n = 327 age-matched adult patients

0.83

Results

0.83

vs. 0.98 MME/kg

Paraspinal interfascial plane block cut opioid use in the first postoperative day

n = 327 age-matched adult patients

More results

The time to first analgesic request was delayed within the first 250 minutes postoperatively in the paraspinal interfascial plane group (P=0.042).

ICU admission and estimated blood loss did not differ between groups.

Conclusion · 1 of 2

Use of the paraspinal interfascial plane block in posterior lumbar spine surgery was associated with reduced early postoperative opioid consumption, decreased length of stay, and less postoperative nausea and vomiting.

Conclusion · 2 of 2

These findings support the potential value of the paraspinal interfascial plane block as an adjunct to multimodal analgesia protocols in posterior lumbar spine surgery. LEVEL OF EVIDENCE: Level III.
