Pain management is important after coronary artery bypass graft (CABG) surgery. Intravenous morphine is the gold standard for pain relief, but its sedation, cough suppression and decreased bowel movements limit its use. Analgesia with regional methods after surgery provides effective analgesia by reducing morphine consumption. In this study we have planned to compare the erector spina plane block with parasternal block +local infiltration to chest tube areas.

Patients who will undergo open heart surgery will be included in this study. Pain management is important after coronary artery bypass graft (CABG) surgery. Poorly controlled postoperative pain can trigger myocardial ischemia, increase catecholamine levels, result in increased complications such as stroke and bleeding, and increase the risk of pneumonia. Intravenous morphine is the gold standard for pain relief, but its sedation, cough suppression and decreased bowel movements limit its use. For this reason, regional methods are gaining importance in pain treatment. After cardiac surgery. Both sternotomy and bilateral chest tubes are the most painful interventions during cardiac surgeries. Parasternal block can be a good alternative in the treatment of pain in CABG surgeries. In parasternal application, the aim is to anesthetize the nerves innervating the sternum between the pectoral muscle and the intercostal muscle by holding the probe in the parasagittal plane on the lateral side of the sternum under USG guidance. Patients who will undergo open heart surgery will be included in this study. The patients will be divided into two groups, and in Group 1, before general anesthesia is given, bilateral ESPB will be performed at the 4-6th thoracic level in the prone position, and then routine general anesthesia will be performed (at this stage, the patients will be given sedation to prevent them from feeling pain). After endotracheal intubation, in Group 2, a parasternal block will be performed from the lateral sternum. At the end of the surgery, local anesthetic infiltration will be perform to the tube sites. General anesthesia and surgical procedures will be performed routinely in both groups. In the intensive care unit patients will be monitored for pain levels, intubation duration, whether there is atelectasis in the lungs, and the need for reintubation. Pain assessment will be evaluated with the behavioral pain score while the patients are intubated and with the visual pain scale after extubation. Whether atelectasis has developed will be evaluated with ultrasonography at the 12th and 24th hours postoperatively
