Retrospective Case Series Comparing the Efficacy of Thoracic Epidural With Continuous Paravertebral and Erector Spinae Plane Blocks for Postoperative Analgesia After Thoracic Surgery.

Perioperative pain management for thoracic surgery plays a vital role in recovery and improved outcomes. In this retrospective study we compare three different regional anesthesia techniques utilized at one institute to provide postoperative analgesia for thoracic surgery. Continuous thoracic epidural analgesia (TEA), thoracic paravertebral block (PVB) and erector spinae plane (ESP) block are compared for postoperative pain management, opioid requirements, postoperative nausea and vomiting (PONV), respiratory events and length of stay. In this study, pairwise comparisons were also performed among the regional techniques with respect to mentioned outcomes.
