Selective blockade of supraclavicular nerves and upper trunk of brachial plexus "The SCUT block" towards a site-specific regional anaesthesia strategy for clavicle surgeries - A descriptive study.

Background And Aims: Commonly, the superficial cervical plexus and interscalene block were combined to provide surgical anaesthesia for procedures on the clavicle, which are neither selective nor site-specific considering the innervation of the clavicle. The aim was to analyse effectiveness and block dynamics of selectively blocking supraclavicular (SC) nerves and upper trunk (UT) of brachial plexus (SCUT BLOCK) as a site-specific regional anaesthesia strategy for clavicle surgery.

Methods: SC nerves and UT were blocked with 3-ml and 5-ml local anaesthetic, respectively, in 70 American Society of Anesthesiologists I and II patients aged above 18 years, undergoing clavicle surgery.
