Pecto-Intercostal Fascial Block vs. Transversus Thoracic Muscle Plane Block in Cardiac Surgery

It has been reported that the TTMP block and PIF block produce effective postoperative analgesia for open cardiac surgeries. The hypothesis of our study; PIF block reduces pain and analgesic consumption in the acute period (0-24 hours) similar to TTP block in patients undergoing elective cardiac surgery requiring median sternotomy. Patients will be divided into two groups: Group PIFB: A bilateral PIF block will be performed intraoperatively (20 ml, %0.25 bupivacaine + 1:400.000 adrenaline). In addition, IV morphine patient-controlled analgesia (PCA) will be applied postoperatively for 24 hours. Group TTMPB: A bilateral TTMP block will be performed intraoperatively (20 ml, %0.25 bupivacaine + 1:400.000 adrenaline). In addition, IV morphine-PCA will be applied postoperatively for 24 hours.
