Serratus Posterior Superior Intercostal Plane Block for Rescue Analgesia After Clavicle Fracture Surgery: A Case Report

Clavicle fractures are the most common fractures of the shoulder girdle. Due to the complex sensory innervation of the clavicle, patients' pain scores are high in the postoperative period. Therefore, multimodal regional analgesia techniques provided by the combination of cervical plexus and/or brachial plexus have been successfully applied in the literature. Serratus posterior superior intercostal plane block (SPSIPB) is a plane block that provides anterolateral chest wall analgesia. It provides analgesia between C3 and T10. In this case report, our experience with SPSIPB, which we applied for rescue analgesia in a patient who underwent surgery for a clavicle fracture, is described.
