Résumé
Open cardiac surgery may cause severe postoperative pain. The authors hypothesized that patients receiving a bundle of care using continuous erector spinae plane blocks (ESPB) would have decreased perioperative opioid consumption and improved early outcome parameters compared with standard perioperative management.Design: A consecutive, patient-matched, controlled before-and-after study.Setting: Two tertiary teaching hospitals.Participants: The study comprised 67 consecutive patients undergoing elective cardiac surgery with cardiopulmonary bypass.
