A Technique Guide In Ultrasound Guided Regional Ankle Blocks

Abstract The use of ultrasound guided regional blocks is supported by the National Institute for Health and Care Excellence of the United Kingdom, for its safety and efficacy. This is a technique guide which is a culmination of the experiences gained in administering regional anesthesia under ultrasound guidance for ankle blocks as part of everyday podiatric surgery practice, based on a sound understanding of the principles of ultrasound science and instrumentation. It is in the opinion of the authors that the positioning of the patient is key, combined with an in-plane ultrasound guided technique, to perform a successful block of the selected nerve based on a foundation of knowledge and experience of anatomy and use of ultrasound respectively. This technique guide depicts annotated ultrasound images of the sonoanatomy to include the five nerves which innovate the foot that are required to be anaesthetised for a selective or complete regional ankle block offering predictable peri-operative anesthesia, post-operative analgesia and early ambulatory discharge.
