Block procedures
Erector Spina Plane Block, anxiety
STERILE, DECUBITUS
Block procedures were performed under general anesthesia before the skin incision to prevent anxiety and ensure patient comfort. Following the anesthesia induction, blocks were performed under US guidance when patients were in the lateral decubitus position. After strict skin antisepsis, the needle insertion area was covered with sterile drapes. In all patients, a high-frequency 6–18 MHz linear probe (MyLab six, Esaote, Genoa, Italy) in a sterile cover and a US-compatible 22-gauge and 8-mm nerve block needle (Pajunk, SonoPlexSTIM, Germany) were used in all groups. The following procedures were performed in the study groups. The nerve block needle was advanced with the in-plane technique under the erector spinae muscles until the interfascial space was reached. After hydrodissection with 2 ml of normal saline, 0.25% bupivacaine was injected with 30 ml in Group 1 (Anatomical view during Erector Spina Plane Block.
