Effects of Erector Spinae Plane Block Method Used in Pain Management in Heart Surgery on Vascular Diameters

Effects of Erector Spinae Plane Block on Sympathectomy in Off Pump Coronary Artery Bypass Surgery

Off-pump coronary artery bypass grafting (OPCABG) is a bypass method performed on the working heart. Pain is a frequently seen side effect experienced following this surgery. Erector spinae plane block is our analgesia method that the investigators routinely perform prior to the surgery to overcome this problem. In this method, analgesic medication is given via a needle in between the two superficial muscle groups (erector spinae muscles) located in participants back. The investigators believe this method not only provides pain relief, but also is beneficial (dilating) on the vessels that will be used for bypassing the clogged vessels during the surgery. The investigators aimed to measure some parameters in this routine procedure before and after performing the analgesic method with an ultrasound (imaging with sound waves).
