This comprehensive third edition provides robust support to clinicians providing perioperative care for patients. Patients with a range of medical conditions undergo surgeries of varying levels of risk, and the evolving field of consult medicine aims to address their needs, whether pre- or post-surgery. This book offers evidence and experience-based information, advice, and guidelines on all aspects of perioperative medicine. Care around surgeries in many major clinical areas are included, including cardiology, pulmonology, gastroenterology, rheumatology, endocrinology, and so on. This new edition has been updated throughout with the latest literature, more visual content (tables and algorithms), and eleven new chapters on topics such as: chronic pain, congestive heart failure, hormone therapy and transgender patients, and postoperative hypoxemia. This new edition focuses on high value care in order to improve outcomes, including minimizing complications and readmissions. It also provides streamlined key points for caring for patients with medical diagnoses that may be especially complicated around surgery. This resource is invaluable for practicing physicians (including medical consultants, surgeons, and anesthesiologists) and other professionals who aim to optimize care of surgical patients.
