Abstract
-adrenoceptor agonist used for sedation, analgesia, and anxiolysis, with minimal respiratory depression; therefore, it is widely used in clinical practice. Transient hypertension has been reported to be an indication for the use of dexmedetomidine. The authors report three female patients who experienced hypertensive crisis when used atropine to treat bradycardia caused by dexmedetomidine. The transient hypertension is a relatively common side effect of dexmedetomidine, hypertensive crisis seen with coadministration of atropine is much less frequently reported. This is the first report to describe the use of atropine to treat bradycardia induced by dexmedetomidine, which may cause severe hypertension in female patients. They discuss the reason for and treatment of hypertension caused by administration of atropine and dexmedetomidine together and review the relevant literature.
