Interventions
Liposomal bupivacaine
The superior trunk was visualized distal to the convergence of the C5 and C6 nerve roots but proximal to the take-off of the suprascapular nerve. The block needle was advanced in-plane to the ultrasound beam in a lateral-to-medial direction under the deep cervical fascia and superficial to the middle scalene muscle, until the needle tip was immediately adjacent to the lateral border of the superior trunk. 1.33% Liposomal bupivacaine 10ml was injected.
