Ultrasound technology is a rapidly emerging science with wide applications in the field of medicine. It is a safe, reliable, relatively inexpensive and portable imaging modality. It plays an important role in identifying the correct anatomy of underlying structures and has therefore served as a very good diagnostic tool in medical science. Current and future applications of ultrasound in the field of anesthesia include regional anesthesia, epidural space identification in cases of difficult anatomy, delineating nerve plexuses for chronic pain procedures, vascular access, airway assessment, lung ultrasound, ultrasound neuro-monitoring, gastric ultrasound, focused transthoracic echo (TTE), transesophageal echo (TEE) and Doppler. Applications of Ultrasound in Anesthesia: A Handbook has been written with the purpose to explain the basics of ultrasound and its applications to young budding anesthesiologists in a very simple understandable language with diagrams and ultrasound photographs wherever required. This book comprises of total eight chapters. The initial chapters in this book deal with the knowledge of ultrasound which includes parts of ultrasound, terminologies and how to do scanning, while in other chapters, ultrasound-guided procedures like central venous access and various regional blocks have been discussed.
