Efficacy of erector spinae plane block for minimally invasive mitral valve surgery: Results of a double-blind, prospective randomized placebo-controlled trial
Authors' conclusion
Following MIMVS, adding an ESP block to a standard multimodal analgesia regimen did not reduce opioid consumption and pain scores.
Study context
- Population
- Patients undergoing video-assisted thoracoscopic minimally invasive mitral valve surgery (MIMVS) via right-sided mini-thoracotomy in an enhanced recovery after cardiac surgery program
- Participants

- Comparison
- Erector spinae plane (ESP) block with ropivacaine 0.5% vs normal saline 0.9% via ESP catheter
- Primary endpoint
- Cumulative morphine consumption
- Follow-up
- First 24 h after extubation
