This prospective randomized trial compared the analgesic efficacy of paravertebral block (PVB) and erector spinae plane block (ESPB) in 57 patients undergoing elective thoracotomy. The study found that PVB resulted in significantly lower intraoperative remifentanil consumption (431.4 ± 287.7 mcg vs 863.6 ± 385.5 mcg, p < 0.001) and reduced postoperative morphine use compared to ESPB.
Key findings
- Intraoperative remifentanil consumption was significantly lower in the PVB group (431.4 ± 287.7 mcg) compared to the ESPB group (863.6 ± 385.5 mcg, p < 0.001).
- Total 24-hour postoperative morphine use was lower in the PVB group (15.2 ± 6.6 mg) than in the ESPB group (20.1 ± 6.6 mg, p = 0.002).
- NRS scores at rest were significantly lower in the PVB group at 9 and 12 hours postoperatively.
- NRS scores during coughing were significantly lower in the PVB group at all postoperative time points.
Why it matters
The findings suggest that PVB may offer superior analgesia compared to ESPB for patients undergoing thoracotomy, potentially leading to better pain management and reduced opioid consumption, which is crucial for recovery and minimizing opioid-related side effects.
