Clavipectoral Fascia Plane Block Versus Interscalen Brachial Plexus Block for Clavicle Surgery

Clavicle fracture is common in men and children after a direct fall on shoulder during sport activity such as cycling or an injury during a traffic accident. The pain after clavicle fracture surgery may be managed with combined superficial cervical plexus-interscalene block (ISCB) and recently clavipectoral fascia plane block (CPB). CPB was defined by Valdes in 2017 firstly. It may be used for postoperative analgesia after clavicle surgery. The clavipectoral fascia covers the clavicular site of the pectoralis major muscle. It provides the potential interfascial space between the clavicle and the pectoralis major muscle. CPB provide effective analgesia after clavicle surgery. It is also easy to perform. With this advantage and its analgesic effectiveness for clavicle surgery, CPB may be an alternative to interscalene brachial plexus block. However, randomized clinical efficacy trials are needed to investigate the effectiveness of CPB for clavicle fractures. In the literature, data about CPB is so limited, however it seems a good alternative to brachial plexus block for pain management after clavicle fracture. The aim of this study is to compare the efficacy of the US-guided CPB and ISCB for postoperative analgesia management after clavicle surgery. The primary aim is to compare perioperative and postoperative opioid consumption and the secondary aim is to evaluate postoperative pain scores (VAS), adverse effects related with opioids (allergic reaction, nausea, vomiting).
