Abstract

Introduction: For preoperative analgesia during a variety of operations, the erector spinae plane block (ESPB) has grown in popularity. However, its effectiveness in lumbar surgery is still unknown. The purpose of this study was to investigate the potential benefits of ESPB in enhancing analgesic efficacy in elderly individuals following posterior lumbar spine surgery.

Methods: Patients aged 65 years or older who underwent elective posterior lumbar instrumented fusion (with or without decompression) at our institution between January 2019 and June 2022 were included. Demographic data, comorbidities, and results of preoperative screening were retrospectively collected. Propensity score matching (PSM) was performed in a ratio of 1:1 for control and ESPB groups. The primary outcome was opioid consumption at 24 h after surgery. Secondary outcomes was visual analog scale (VAS) pain scores at rest in the first 24 h. Additional secondary outcomes included number of patients requesting rescue analgesia, incidence of nausea and vomiting, time to the first request for analgesia via patient-controlled analgesia, and length of stay.

Results: A total of 382 patients were included, of whom 119 received ESPB. The mean age of the study patients was 70.6 years old, and 254 (66.5%) were male. After PSM, each group comprised 115 patients. Patients in the ESPB group showed a significantly lower opioid consumption at 24 h after surgery. Compared with the control group, VAS pain scores at rest in the first 24 h, number of patient-controlled intravenous analgesia (PCIA) pump compressions, ratio of patients requesting rescue analgesia, incidence of nausea and vomiting, and length of stay were significantly reduced in the ESPB group. There were no significant differences between the two groups regarding safety outcomes.

Conclusions: ESPB reduces short-term opioid consumption while providing safe and effective analgesia in elderly patients undergoing posterior lumbar surgery.
