Erector spinae plane block improves postoperative recovery after laminectomy and discectomy surgery: a retrospective...

There is still room for improvement of pain management after spinal surgery. The goal of this study was to evaluate adding the erector spinae block to the standard analgesia regimen. Our hypothesis was that the erector spinae plane block will decrease length of hospital stay, reduce opioid need and improve numeric rating scale pain scores.

This was a single center retrospective cohort study. We included 418 patients undergoing laminectomy or discectomy from January 2019 until December 2021. The erector spinae plane block was introduced in 2016 by Forero and colleagues and added to our clinical practice in October 2020. Patients who did not receive an erector spinae plane block prior to its implementation in October 2020 were used as control group. The primary outcome measure was functional recovery, measured by length of hospital stay. Secondary outcome measures were perioperative opioid consumption, need for patient-controlled analgesia and numeric rating scale pain scores. Postoperative data collection time points were: at the PACU and after 3, 6, 12 and 24 h postoperatively.

There was a significant shorter length of hospital stay in patients undergoing single level laminectomy (with erector spinae plane block 29 h (IQR 27-51), without block 53 h (IQR 51-55), p < .001), multiple level laminectomy (with erector spinae plane block 49 h (IQR 31-54), without block 54 h (IQR 52-75), p < .001) and discectomy (with erector spinae plane block 27 h (IQR 25-30), without block 29 h (IQR 28-49), p = .04).

Erector spinae plane block reduces length of stay after laminectomy surgery.
