With the introduction of cardiac surgery more than five decades ago and the use of the heart-lung machine for open heart surgical procedures granting the surgeon unlimited time in which to operate inside the heart, a complex task has been given to the Perfusionist. With a pairing of a perfusionist and a surgeon for each chapter, On Bypass: Advanced Perfusion Techniques is an essential collection of techniques and protocols to aid in the difficult and immediate decision making in the operating room. Among the topics covered in this comprehensive text are pediatric perfusion techniques for complex congenital, separation from cardiopumonary bypass, blood flow during cardiopumonary bypass, and minimally invasive perfusion techniques. Also covered is ultrafiltration in cardiac surgery, echocardiography and cardiopulmonary bypass, and advances in long-term pulmonary support. With nearly 650,000 procedures requiring cardiopulmonary bypass and a perfusionist, On Bypass: Advanced Perfusion Techniques answers the need for a textbook that investigates advanced perfusion techniques that are currently being practiced.

Zusammenfassung
In On Bypass: Advanced Perfusion Techniques, editors Linda Mongero and James Beck have distilled the complex field of extrac- poreal circulation and intraoperative mechanical support down to its most basic and important components. By identifying the critical pieces of the complex puzzle that is cardiopulmonary bypass and having these presented by a truly all star cast of contributing authors, On Bypass represents a comprehensive, in depth compilation of the current sta- of the art in cardiopulmonary bypass technology and techniques. In chapters dedicated to engineering, cannulation, blood flow, prime solutions, and ultrafiltration, the reader is exposed to detailed descr- tions of the foundations of cardiopulmonary bypass technology. Other chapters illuminate the nuances of perfusion in special situations, such as pediatric, minimally invasive, and aortic surgery. Extension of ext- corporeal support beyond the operating room is covered expertly in a chapter on EeMO and long term pulmonary support. But this book goes beyond the traditional boundaries of a perfusion manual, and it is significantly strengthened by clinically oriented chapters dedicated to separation from cardiopulmonary bypass, the inflammatory response, and echocardiography. Finally, the editors draw upon their more than 50 years of experience as cutting edge perfusionists in a chapter on policies and procedures, which constitutes required reading for anyone managing a perfusion program. In sum, On Bypass represents an authoritative compendium of the most recent and best knowledge in every area relevant to cardiopul- nary bypass and perfusion.
