Comparison of Paravertebral Block and Erector Spinae Plane Block in Thoracotomy Using Nociception Level Index Monitoring: A Prospective Randomized Trial
Authors' conclusion
In patients undergoing thoracotomy, PVB provided superior intraoperative and postoperative analgesia compared with ESPB, with significantly reduced opioid requirements and lower pain scores.
Study context
- Population
- Patients undergoing elective thoracotomy, nociception level (NOL) index-guided intraoperative opioid administration
- Participants
- 57 patients
- Comparison
- Preoperative ultrasound-guided paravertebral block (PVB) vs erector spinae plane block (ESPB) at T5
Methodological detailsprospective, single-centre
- Prospective
- Single-centre
Primary result
As reported in the abstract
Intraoperative remifentanil consumption
P < 0.001
Further findings
Total 24-h postoperative morphine use
P = 0.002
Numeric rating scale (NRS) pain scores
- NRS at rest significantly lower with PVB at 9 and 12 hours
- NRS during coughing significantly lower with PVB at all postoperative time points
