This review book is based on the keyword list distributed to residency program directors each year. Each of the 316 entries begins with a keyword, followed by a list of key points and a one- or two-page discussion written by a resident and reviewed by Yale University faculty. Entries cover all areas of anesthesiology, including pediatric anesthesia. For easy reference, the book is indexed in three ways—alphabetically, by rotation or organ system, and according to the Boards organization.
