Many regional techniques have been used to manage postoperative pain in cardiac surgery, including thoracic epidural anesthesia, paravertebral, intercostal nerve block, intrathecal spinal morphine, and local infiltration. Increased risk of epidural/spinal hematoma secondary to systemic heparinization, potential hemodynamic instability, technical difficulties and complications such as pneumothorax are potential serious drawbacks. Due to the aforementioned reasons, anesthetists are understandably preferring ultrasound (US) guided interfascial plane blocks, which are generally thought to provide safer and more effective analgesia in cardiac surgery.~This study aims to evaluate and compare the effects of ESPB versus ESPB plus Superficial PIPB on pain scores and opioid consumption in patients undergoing elective cardiac surgery.~Patients will be divided into two groups:~Group ESPB:~In this group, patients will be administered bilateral ESPB (total of 40 ml, %0.25 bupivacaine) in addition to IV morphine patient-controlled analgesia (PCA) for the first 24 postoperative hours.~Group ESPB+Superficial PIPB:~In this group, patients will be administered Bilateral ESPB (total of 40 ml, %0.25 bupivacaine) and bilateral Superficial PIPB (total of 20 ml, %0.25 bupivacaine). In addition, IV morphine PCA will be administered for the first 24 postoperative hours.
Cardiac surgery is associated with significant postoperative pain. Pain control is an essential part of enhanced recovery protocols. The aim of this study is to evaluate and compare the analgesic efficacies of erector spinae plane block (ESPB) and the combination of ESPB and superficial parasternal intercostal plane block (PIPB) in patients undergoing elective cardiac surgery.
