Postoperative pain treatment with erector spinae plane block and pectoralis nerve blocks in patients undergoing mitral/ tricuspid valve repair — a randomized controlled trial

Effective postoperative pain control remains a challenge for patients undergoing cardiac surgery. Novel regional blocks may improve pain management for such patients and can shorten their length of stay in the hospital. To compare postoperative pain intensity in patients undergoing cardiac surgery with either erector spinae plane (ESP) block or combined ESP and pectoralis nerve (PECS) blocks.
