Summary
Brief summary (as posted)
Rhomboid intercostal block is used to block lateral cutaneous branches of intercostal nerves between T3 and T9 dermatomes. RIB has been reported to be successful in attenuating acute pain following breast surgeries. However, it's effect on chronic pain has not been evaluated yet. The primary hypothesis of the study is that the incidence of chronic pain of the patients who will receive Rhomboid intercostal block (RIB) following breast cancer surgery will be lower than the patients who will receive no block intervention at the postoperative 3rd month. The secondary hypothesis is that the incidence ofchronic pain of the patients who will receive Rhomboid intercostal block (RIB) following breast cancer surgery will be lower than the patients who will receive no block intervention at the postoperative 6th month. An other secondary hypothesis is that the total BPI-SF scores will be lower in the RIB group than control group at the postoperative 3rd and the 6th months.

- description
- After endotracheal intubation, patients will be positioned in lateral decubitus position. A linear ultrasound probe will be placed at the edge of scapula at the level of T5-T6. Under sterile conditions, the landmark points (rhomboid major muscle, 5th and 6th ribs, and intercostal muscles) will be observed and a block needle will be directed to the interfacial plane between rhomboid major muscle and intercostal muscle. RIB will be performed by injecting 30 ml of bupivacaine 0.25%.
