AbstractIntroduction Various regional anesthesia techniques such as thoracic epidural, thoracic paravertebral block, erector spinae plane block (ESPB), parasternal intercostal blocks are used in cardiac surgery for postoperative analgesia. In our study, we investigated the analgesic efficacy of the dual injection technique of ESPB in beating heart coronary bypass surgeries. Methods The records of patients with coronary artery bypass (CABG) surgery in the beating heart at the VKV American Hospital between January and December 2019 were retrospectively analyzed. The data of 30 patients who met the criteria to be included in the study were analyzed. Whether any opioid use is required for maintenance of anesthesia it is recorded. The pain scores of the patients are recorded by the intensive care team and cardiovascular service nurses for the first 48 hours. Results The absence of secondary responses to pain in all surgical periods, including skin incision and sternotomy, and low number of rating scale (NRS) scores in the postoperative 0- to 24-hour period show that the technique we developed can produce effective analgesia. After the 24th postoperative hour, the patients were followed up in the cardiovascular service and there was no opioid use between 24- to 48-hour period. Conclusion Our approach, in which the local anesthetic is applied by approaching the superior costa-transverse ligament (SCTL) in the ESPB, provides an effective analgesia in coronary artery bypass surgeries in the beating heart. The main purpose of our new approach is to increase the amount of local anesthetic in the paravertebral area. We recommend using our modified technique for effective analgesia after CABG surgeries.Copyright © 2021, Coşarcan et al.
