I used this book during anesthesia school to prepare for cases. I think there is some helpful information on surgical technique and possible complications. However, as far as how to prepare for the case, I’d use the phone app created by Vargo. His app is a wealth of knowledge beyond case preparation. The Vargo app is also the most up to date information I’ve seen concerning how to manage and prepare for cases, while Jaffe’s book does not seem current.
