Paravertebral Block for Proximal Humeral Fracture Surgery

Ultrasound guided T2 thoracic paravertebral block is added in ICTP group. After interscalene brachial plexus block and superficial cervical plexus block have been administrated, selective 2nd thoracic nerve root(T2) will be blocked with 10 ml of 0.25% ropivacaine(naropin).

An ultrasound-guided IC block using an ultrasound machine (Sonosite, USA), and an linear array probe with a sterile cover and a 22G(Gauge) block needle is performed. An in-plane approach, advancing the needle along the longitudinal axis of the ultrasound transducer and visualizing the entire shaft is employed. Twenty ml of 0.375% ropivacaine(naropin) is injected around brachial plexus and 10 ml of 0.25% ropivacaine around superficial cervical plexus.
