Here we aimed to study the effectiveness of dexmedetomidine as an anesthetic adjunct in surgery. ⋯ Dexmedetomidine can stabilize blood pressure and heart rate, and prevent postoperative adverse reactions. However, patients with original hypovolemia or heart block should be cautious. Besides, the quality of such studies should be improved in methodology to evaluate their efficacy and safety comprehensively.
