The invention discloses a new use of dexmedetomidine. The new use of the dexmedetomidine or its pharmaceutically acceptable salt provided by the invention refers to application in preparation of: 1) products for prevention and/or treatment of postoperative sleep disorders; 2) products for prevention and/or reduction of postoperative complications; and 3) products for improvement of postoperative determination. Efficacy tests show that for the elderly non-cardiac surgery patients, small dose dexmedetomidine intravenous infusion can significantly improve the postoperative sleep structure and subjective sleep quality, and at the same time can improve patient prognosis, which includes lowering pain degree, reducing postoperative delirium and non-delirium complications and shortening ICU retention time. |
