Comparison Between Clavipectoral Fascia Block & Interscalene Brachial Plexus Block As Regard Adequacy of Anesthesia in Clavicle Surgeries

Clavicle fractures represent 2.6% of all fractures and are commonly seen in emergency and surgical settings, particularly among young men due to sports or traffic incidents, predominantly affecting the mid-clavicle. Surgical intervention often yields better functional outcomes compared to conservative treatment. While general anesthesia is an option, it carries risks such as nausea, vomiting, and increased costs for patients. In contrast, regional anesthesia can effectively manage pain while minimizing complications associated with general anesthesia.

The supraclavicular nerve innervates the skin above the clavicle, but the sensory innervation of the clavicle itself remains debated. A combination of superficial cervical plexus block (SCPB) and interscalene brachial plexus block (ISBP) is frequently employed during clavicle fracture surgeries. The brachial plexus includes nerves from C5-8 and T1, while the cervical plexus comprises branches from both deep and superficial cervical structures. Although this combination can effectively address pain management during surgery, ISBP may lead to complications like diaphragmatic paralysis due to phrenic nerve involvement.
