Abstract

Now in a revised and expanded 7th Edition, Kaplan’s Cardiac Anesthesia helps you optimize perioperative outcomes for patients undergoing both cardiac and noncardiac surgery. Dr. Joel L. Kaplan, along with associate editors, Drs. John G. T. Augoustides, David L. Reich, and Gerard R. Manecke, guide you through today’s clinical challenges, including the newest approaches to perioperative assessment and management, state-of-the art diagnostic techniques, and cardiovascular and coronary physiology.

  • Complete coverage of echocardiography and current monitoring techniques.
  • Guidance from today’s leaders in cardiac anesthesia, helping you avoid complications and ensure maximum patient safety.
  • More than 800 full-color illustrations.
  • A new section on anesthetic management of the cardiac patient undergoing noncardiac surgery.
  • New availability as an eBook download for use the in OR.
  • Online-only features, including quarterly updates, an ECG atlas...an increased number of videos, including 2-D and 3-D TEE techniques in real time...and an Annual Year End Highlight from the Journal of Cardiovascular Anesthesia that’s posted each February.
