Effect of the Paravertebral Block on Chronic Postsurgical Pain After Thoracic Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Authors' conclusion
Thoracic PVB does not prevent CPSP after thoracic surgery.
Study context
- Population
- Adults undergoing thoracic surgery
- Participants
- 1,028 adults · 10 randomized controlled trials (RCTs)
- Comparison
- Thoracic paravertebral block (PVB) vs no block or other blocks
- Outcome
- Incidence of chronic postsurgical pain (CPSP)
- Follow-up
- 3 months

Postoperative pain at rest · 24 and 48 hours
- PVB significantly decreased pain at rest at 24 and 48 h vs no block
- Pain score higher with PVB than other blocks at rest at 48 h
