Research progress of dexmedetomidine for elderly patients during anesthesia / 天津医药

Degenerative changes in autonomic nervous system happen in elderly. The cardiac function reduces, the ability of regulating the target organ decreases, and the stability of hemodynamics is not easy to maintain in old people. How to maintain the hemodynamic stability of elderly patients during anesthesia has become the focus of clinical research. Dexmedetomidine, as a new type of 2- alpha adrenergic agonist, has the function of anti-anxiety, sedation, analgesia and anti-sympathy, and which is wildly used in clinic. This article describes the research progress of dexmedetomidine used in elderly patients during anesthesia.
