Postoperative complications refer to adverse events that can occur following a surgical procedure. These complications can range from minor issues, such as nausea or wound infections, to more serious complications like blood clots or organ damage. Common postoperative complications include pain, bleeding, infection, and complications related to anesthesia. Proper preoperative evaluation, careful surgical technique, and postoperative monitoring are all important factors in reducing the risk of postoperative complications. Prompt recognition and treatment of any complications that do arise are essential to ensure the best possible outcome for the patient.
