Axillary brachial plexus block is one of the most frequently employed peripheral blocks. The popularity of axillary block stems from its success as a safe and relatively easy technique with numerous applications. The technique of axillary block has evolved. It was modified after the development of precise nerve localization modalities. Currently, ultrasound is the most important localization technique for regional anaesthesia. Ultrasound-guided axillary block encompasses a spectrum of techniques. The selection of a specific technique can be adjusted to an operator's individual level of skill and proficiency. Axillary block under US-guidance can be performed using a traditional perivascular method and by placing a selective blockade of individual nerves that supply the surgical area. Regardless of the selected method, it enables the incorporation of individual patient anatomical variation in an anaesthesia plan. This paper discusses the technical details and efficacy issues of US-guided axillary brachial plexus block techniques.
