Surgery theory refers to the principles and concepts that guide surgical practices and techniques. It encompasses the understanding of human anatomy, the physiological responses to surgical interventions, and the various methods used to treat medical conditions through surgical procedures. This theory helps surgeons make informed decisions during operations to ensure patient safety and optimal outcomes. In addition to anatomy, surgery theory also includes the study of surgical instruments, anesthesia, and post-operative care. By integrating knowledge from related fields such as biology, pharmacology, and medical ethics, surgery theory aims to improve surgical techniques and enhance patient recovery, ultimately contributing to advancements in the field of medicine.
