Efficacy of Interscalene Block versus Interscalene Block with Superficial Cervical Plexus Block for Proximal Humerus surgery under General Anaesthesia - a randomized Controlled double blinded Trial

Proximal humerus fractures are among the most prevalent fractures in adults, accounting for approximately 4–7% of all fractures. They are particularly common in older adults. The shoulder joint is predominantly innervated by the suprascapular nerve, axillary nerve (C5–6) and lateral pectoral nerves (C7). Part of the anterior surface of the shoulder is innervated by the supraclavicular nerve (C3–4). Therefore, blockade of the brachial plexus and the cervical plexus (IC block) is basically required.Interscalene block (ISB) might not cover the comprehensive dermatome distribution to provide adequate anaesthesia for patient undergoing proximal humeral fracture surgery, so addition of superficial cervical plexus block (SCPB) along with ISB will provide supplemental analgesia. In regard to the neuronal anatomy and clinical experience, the combined interscalene-cervical plexus block seems to be an effective block and may be a promising method for sufficient surgical anesthesia in clavicle surgeries ,but, there are no sufficient articles on same block comparison in Proximal Humerus Surgeries.

Hence we will be conducting a Randomised Control Trial with the objective to assess the Analgesic efficacy of SCPB added with ISB for proximal humerus surgeries within the 2 study groups.
