Erector spinae plane block (ESPB) enhances hemodynamic stability decreasing analgesic requirements in surgical stabilization of rib fractures (SSRFs).

Objective: To evaluate the efficacy of erector spinae plane block (ESPB) on intraoperative hemodynamic stability, opioid and inhalation anesthetic requirements and postoperative analgesic effects in patients undergoing surgical stabilization of rib fractures (SSRFs).
Methods: We retrospectively reviewed 173 patients who underwent surgical stabilization of rib fractures between May 2020 and December 2023. The patients were allocated into the ESPB group or the control group. Demographic data, intraoperative hemodynamic parameters, total intraoperative opioid consumption, the average minimum alveolar concentration (MAC) of inhalational anesthetics, postoperative simple analgesics and opioid consumption and the length of hospital stay were included in the analysis.
Results: Compared with the control group, the ESPB group had a lower heart rate (HR) in the first 90 min after surgical incision and lower systolic blood pressure (SBP) and mean arterial pressure (MAP) at the beginning of surgery. Intraoperatively, a notable reduction in fentanyl consumption was observed in the ESPB group (p = 0.004), whereas no significant difference was observed in the average MAC of inhalational agents (p = 0.073). Postoperatively, the ESPB group required fewer doses of simple analgesics in the first 24 h (p < 0.001) and 48 h (p = 0.029). No statistically significant difference in the length of hospital stay (p = 0.608) was observed between the groups.
Conclusion: ESPB was shown to enhance intraoperative hemodynamic stability, reduce opioid consumption and decrease postoperative analgesic consumption in patients who underwent SSRF. These results suggest that ESPB may serve as a valuable component of multimodal analgesia protocols for SSRF. Larger prospective studies are warranted to confirm the results and evaluate long-term outcomes.
