Parasternal Block and Recto-Intercostal Fascial Plane Block:Superficial PSB is performed bilaterally with the patient in the supine position using a high-frequency linear USG probe. The probe is inserted longitudinally 2cm lateral to the sternal border to visualize the T2T4 intercostal space and identify the pectoralis major muscle, intercostal muscle, and pleura. Using an in-plane approach with a 100mm needle, 10ml of 0.25% bupivacaine is administered between the pectoralis major and intercostal muscle. Additionally, a Recto-Intercostal Fascial Plane Block is performed bilaterally with a high-frequency linear USG probe. The probe is inserted 2-3cm lateral to the xiphoid to visualize the rectus abdominis muscle and the 6th-7th cartilages. The needle is advanced to the plane between the costal cartilage and the rectus abdominis muscle using the in-plane technique, and 1-2ml of saline is injected. After spreading to the target plane is observed, 20ml of 0.25% bupivacaine is administered.

Superficial PSB is performed with the patient in the supine position using a high-frequency linear USG probe. The probe is placed longitudinally 2cm lateral to the sternal border to identify the T2T4 intercostal space, pectoralis major muscle, intercostal muscle, and pleura. Using an in-plane approach with a 100mm needle, 10ml of 0.25% bupivacaine is applied between the pectoralis major and intercostal muscle. Additionally, an erector spinae plane block is performed with a high-frequency USG probe. Erector spinae plane block is performed under general anesthesia, in the lateral position, under USG guidance, after sterilization, by inserting a needle between the deep surface of the erector spinae muscle and the transverse process with an in-plane approach in the craniocaudal direction. If no air or blood is seen in the aspiration, a 2mL serum test dose is applied to this area and a total of 20mL of 0.25% bupivacaine is injected bilaterally to perform an erector spinae plane block.
