Preoperative evaluation refers to the process of assessing a patient's overall health and medical history before they undergo surgery. This evaluation helps to identify any potential risks or complications that may arise during the surgical procedure and allows healthcare providers to optimize the patient's condition before surgery. The preoperative evaluation typically includes a comprehensive physical examination, review of the patient's medical history, laboratory tests, imaging studies, and consultations with specialists if needed. The goal of this evaluation is to ensure that the patient is well-prepared for surgery and to minimize the risk of complications during and after the procedure. Overall, preoperative evaluation plays a vital role in ensuring the safety and success of surgical procedures by identifying and addressing any potential issues that may impact the patient's surgical outcome.
