Ultrasound-guided Clavipectoral Fascial Plane Block Versus Ultrasound-guided Superficial Cervical Plexus Block in Patients Undergoing Fracture Clavicle Operation

The clavipectoral fascial plane block (CPB) is a novel regional anesthesia technique that has been utilized for clavicular fracture surgery. It has been hypothesized that the CPB is an effective regional anesthesia technique for peri-operative analgesia since the terminal branches of many of the sensory nerves like suprascapular, subclavian, lateral pectoral, and long thoracic nerves pass through the plane between the clavipectoral fascia and the clavicle itself.

The ultrasound-guided superficial cervical plexus (SCP) block may be useful for providers in emergency care settings who care for patients with ear, neck, and clavicular region injuries, including clavicle fractures and acromioclavicular dislocations. The SCP originates from the anterior rami of the C1-C4 spinal nerves and gives rise to 4 terminal branches (greater auricular, lesser occipital, transverse cervical, and suprascapular nerves) that provide sensory innervation to the skin and superficial structures of the anterolateral neck and sections of the ear and shoulder.
