Intended for surgical interns and residents, this handbook offers practical and humane guidance in their first steps in the operating theatre. Combining knowledge, know-how and interpersonal skills, it covers both the technical basics of surgery (asepsis, instruments, sutures, perioperative care, etc.) and dimensions that are often neglected: communication, stress management, empathy, teamwork. Clearly structured, illustrated and accessible, it aims to bridge the gap between taught theory and hospital reality. A true field guide, this book aims to train complete, competent and humane surgeons, while serving as a pedagogical tool for trainers. It is part of an approach based on transmission, high standards and benevolence.
