Since patients are rarely exposed to the confined environment of the operating room and are not aware of the specific surgical procedure, it is easy to develop preoperative nervousness. Generally speaking, patients’ preoperative nervousness can be relieved by the following methods: First, patients can be fully informed of the necessity of surgery and the surgical procedure, and have sufficient psychological expectation and acceptance of the postoperative recovery situation. Second, the patient can be introduced to the patient’s medical records of similar surgical patients with better recovery, so that patients see for themselves and reduce their own tension and pressure through mutual communication between patients. Third, if necessary, the patient can be given intravenous Valium to reduce the patient’s anxiety and tension. When communicating with patients, try to be amiable, answer all questions, and give full encouragement and comfort to patients, which can also effectively relieve patients’ preoperative tension and anxiety and make their surgery go smoothly.
