Interventions
Serratus Posterior Superior İntercostal Plane (SPSIP) Block will be performed before the surgery in seated position, under standard sterilization conditions.A linear ultrasound probe will be placed in the sagittal plane along the medial border of the scapula, and the second and third ribs, relevant muscles, and the pleura will be identified. The needle will be advanced into the interfascial plane between the serratus posterior superior and intercostal muscles. After confirmation with salin injection , the block will be performed by injecting 30 mL of 0.25% bupivacaine, and the cranio-caudal spread will be visualized under ultrasound.
