This is a highly informative and carefully presented book for trainees and postgraduate students of anaesthesiology as well as practicing clinicians. This book aims to help them in selecting and implementing the most suitable regional block in each clinical scenario and successfully use the techniques of RADIOLOGIA-guided regional anaesthesia (USRA) in their practice. This book covers basics of RADIOLOGIA imaging, anatomical aspects and techniques of all nerve blocks that are commonly used in clinical practice in a lucid and illustrated presentation. Regional anaesthesia can be a safe alternative to general anaesthesia. When combined with general anaesthesia, it can provide excellent postoperative analgesia too. With the advent of RADIOLOGIA, the scope, safety and reliability of regional anaesthesia have expanded manifold.
