Awake Single-Stage Bilateral Clavicle Surgeries Under Bilateral Clavipectoral Fascial Plane Blocks: A Case Report and Review of Literature

The clavicle is a frequently fractured bone with an infrequent bilateral occurrence. Regional anesthesia (RA) for clavicle surgeries is always challenging due to its complex innervations arising from the two plexuses (cervical and brachial). Various RA techniques described for clavicle surgeries include plexus blocks, fascial plane blocks, and truncal blocks. Plexus blocks are associated with undesirable effects, such as phrenic nerve blockade and paralysis of the entire upper limb, limiting their application for bilateral clavicle surgeries. The clavipectoral fascial plane block (CPB) is a novel, procedure-specific, phrenic-sparing, and motor-sparing RA technique that can provide anesthesia or analgesia for clavicle surgeries. The decision to use the CPB and/or other RA techniques may depend on the site of clavicle injury or variations in clavicular innervation. We report a case of single-stage bilateral clavicle surgery successfully managed with a bilateral CPB alone using ultrasound guidance and landmark guidance separately. The patient was kept awake and comfortable throughout the surgery. In conclusion, CPB can be an effective alternate RA technique in avoiding undesired side effects of more proximal techniques such as phrenic nerve involvement and motor blockade of upper limbs. Landmark-guided CPB can be an alternative with equianalgesic efficacy as of ultrasound-guided CPB in resource-poor or emergency settings.
