Brief summary

Shoulder arthroscopy is one of the frequently performed surgical procedures today. After shoulder surgery, ensuring sufficent analgesia is necessary for both the patient's comfort and for the early and regular performance of the required postoperative rehabilitation exercises. Nerve blocks provide better pain control, opioid consumption in the postoperative period, and consequently have advantages such as fewer side effects and lower risks of pulmonary and cardiac complications. Multimodal analgesia approach is preferred for patients undergoing shoulder arthroscopy. Along with intravenous analgesic agents, peripheral nerve blocks (applied to every suitable and consenting patient) are performed based on patient preference. This study aims to compare the analgesic efficacy in the postoperative period of patients undergoing shoulder arthroscopy with a combination of interscalene brachial plexus block and superficial cervical plexus block with serratus posterior superior intercostal plane block.

Interventions

DRUGSerratus posterior superior intercostal plane block

Serratus posterior superior intercostal plane block is performed, under US guidance, before the surgical operation, and the induction of anesthesia, and when the patient is placed in the prone position.

DRUGInterscalene brachial plexus block and superficial cervical plexus block

İnterscalene brachial plexus block and superficial cervical plexus block is performed, under US guidance, before the surgical operation, and the induction of anesthesia, and when the patient is placed in the prone position.
