Efficacy of Erector Spinae Plane Block in Caridac Surgery

Introduction: Opioid-based pharmacological treatment is frequently used in the treatment of pain after coronary artery bypass graft (CABG) surgery. If adequate postoperative analgesia is not provided in such surgeries, pulmonary and cardiovascular complications may develop. This study aimed to provide effective analgesia and reduce postoperative opioid consumption by applying preemptive erector spinae plane (ESP) block. Methods: A total of 50 patients who underwent CABG surgery were included in this prospective randomized controlled study. Patients were randomly divided into two groups: the ESP group and the control group. The intervention to the ESP group was applied bilaterally at the T5 level before the surgery. The primary outcome was postoperative opioid consumption; the other outcomes included visual analog scale scores, intraoperative opioid consumption, and duration of hospital stay.
