No matter how big or small the surgery is, the patient is bound to be a bit mentally stressed before the surgery. It is because of the patient’s preoperative nervousness that normal sleep is affected. Especially in menopausal female patients, the incidence of preoperative insomnia is higher. For patients with preoperative insomnia, the surgeon can patiently and carefully explain the anesthesia and surgical plan and safety measures to eliminate the patient’s worries. Most of the patients’ sleep can be improved by relaxing their nervousness. If the explanation does not work, the patient can be given an appropriate amount of sleeping pills orally before bedtime. The dosage of sleeping pills should be appropriate. If the patient is old and frail, the dosage of sleeping pills should be reduced as appropriate; if the patient is young and strong, the dosage of sleeping pills can be increased as appropriate.
