Effect of dexmedetomidine as an adjuvant in erector spinae plane block on postoperative analgesia in thoracolumbar spine surgery with an opioid free anaesthesia technique: A prospective randomized clinical trial.

In 30 seconds

This randomized controlled trial evaluated the efficacy of dexmedetomidine as an adjuvant in erector spinae plane block for postoperative analgesia in 40 patients undergoing thoracolumbar spine surgery with opioid-free anesthesia. The addition of dexmedetomidine significantly extended the pain-free period to 15 hours compared to 8.3 hours in the control group (P = 0.001).

Key findings

• Group RD had a pain-free period of 15 hours vs 8.3 hours in Group R (P = 0.001).
• Pain scores at 4, 6, and 8 hours were significantly lower in Group RD (P = 0.015, 0.001, 0.001).
• Group RD required less second-line rescue analgesia (P = 0.001).
• Patient satisfaction was significantly higher in Group RD (P = 0.001).

Why it matters

Effective postoperative pain management is crucial for recovery in spine surgery. This study suggests that dexmedetomidine can enhance analgesia and patient satisfaction while reducing the need for additional analgesics in an opioid-free setting.
