Anesthesiology and Pain Medicine

Dr Tsui completed his medical undergraduate training at Dalhousie University, Halifax, in 1995 after obtaining his Masters of Science in Pharmacy in 1991. These degrees followed a Diploma in Engineering and Bachelors of Science in both Mathematics and Pharmacy. Dr. Tsui completed his anesthesia residency training at the University of Alberta Hospital in Edmonton in 2000, and he received further experience in pediatric anesthesia at B.C. Children's Hospital in Vancouver.

Currently, Dr. Tsui is a Professor in the Department of Anesthesiology and Pain Medicine at the University of Alberta. In his position as an adult and pediatric anesthesiologist at the University of Alberta Hospital (UAH) and Stollery Children’s Hospital, he specializes in regional anesthesia techniques. Dr. Tsui is Director of the Regional Anesthesia and Acute Pain Service at the UAH and Site Chief for Anesthesia at the Cross Cancer Institute in Edmonton. Nationally, he holds positions with the Canadian Anesthesiologists’ Society  Canadian Journal of Anesthesia (editorial board member), American Society of Regional Anesthesia (Member, Education and Annual Meeting Program Committees), and the journal Regional Anesthesia and Pain Medicine (Associate Editor). Dr. Tsui is also a Member of the Association of Canadian University Departments of Anesthesia (ACUDA) Research Committee.

Dr. Tsui is an avid and internationally recognized researcher in many areas of regional anesthesia. During his residency, Dr. Tsui developed an interest in improving the accuracy of epidural catheter placement and was issued a U.S. patent in relation to his research. Dr. Tsui has expanded his research into the use of ultrasound in regional anesthesia, with particular relevance to peripheral nerve block performance. Dr. Tsui is also responsible for development of the E-Catheter catheter-over-needle kit for use during peripheral nerve blocks. The primary objective of his research is to transform regional anesthesia from an “art” into a reliable and reproducible “science” by further exploring the basic scientific and clinical aspects of electrophysiologic signal monitoring and integrating this with the latest advances in ultrasound.

Dr. Tsui is an Alberta Heritage Foundation for Medical Research (AHFMR) Clinical Scholar and has previously received research awards and grants from the Canadian Institutes of Health Research (CIHR), Canadian Anesthesiologists’ Society, AHFMR, and University of Alberta. In 2015, a prestige award, CAS Research Recognition Award, was presented by the Canadian Anesthesiologists’ Society to Dr. Tsui "in recognition of significant research contributions to regional anesthesia, acute pain management and pediatric anesthesia in Canada and around the world".

To date this is the only textbook that and/or atlas devoted entirely to ultra-sound-guided regional blockade. The main objective of this book is to enable anesthesiologists who are beginning to use ultrasound-guided regional anesthesia to shorten their learning curve. For those anesthesiologists already experienced in ultrasound guidance during regional anesthesia, hopefully this atlas will further add to their knowledge in this field.
