The analgesic effect of ultrasound-guided cervical erector spinae block in arthroscopic shoulder surgery: a randomized controlled clinical trial.

研究概要

Seventy patients undergoing arthroscopic shoulder surgery were randomized to receive either ultrasound-guided cervical erector spinae plane block (ESPB) (n=35) or no block (control group, n=35). The primary outcome of interest was static visual analogue scale (VAS) pain scores at 4, 12, and 24 hours post-surgery. Secondary outcomes included intraoperative remifentanil consumption, the Bruggrmann comfort scale (BCS), the quality of recovery-15 (QoR-15) score, the need for rescue analgesia within 24 hours, and adverse events. Outcomes were assessed over the perioperative period and up to 24 hours postoperatively. Overall, the ESPB group demonstrated significantly lower VAS pain scores, reduced remifentanil consumption, better recovery quality (higher QoR-15 scores), and fewer patients requiring rescue analgesia. No serious complications were observed, suggesting that cervical ESPB is a safe and effective option for postoperative analgesia following arthroscopic shoulder surgery.
