Dexmedetomidine is an elective alpha-2 adrenergic agonist, being used in anesthesia practice. It offers sedative, anxiolytic, analgesic, muscle relaxant, and sympathetic lytic properties. While respiratory effects are considered minor, there are important cardiovascular side effects with bradycardia and hypotension being the most common. This article presents a case of a patient, with significant comorbidities and polypharmacy, who was scheduled for cataract surgery under dexmedetomidine sedation. During the administration, severe hemodynamic deterioration was observed with bradycardia and hypotension leading to asystole. Cardiac arrest was successfully managed in accordance with the guidelines of the European Resuscitation Council. Despite the promising role of dexmedetomidine in anesthesia practice, the associated adverse effects cannot be ignored. For this reason it is obligatory to have the minimum mandatory monitoring in accordance with the safety and quality guidelines.
