Effects of Supplemental Dexmedetomidine Anesthesia on Intracranial Aneurysm Patients Undergoing Intracranial Interventional Embolization.

Intracranial aneurysm (IA) has been identified in approximately 0.4%−3% of the population and associated with 3%−10% mortality. IA is the major factor attributing to spontaneous subarachnoid hemorrhage. We aim to investigate that whether employing dexmedetomidine (DEX), an α2 adrenergic receptor agonist, as a supplementation could impact the outcomes of patients with intracranial interventional embolization. Patients were randomly divided into a control group (n = 48 cases) and a DEX (0.6 μg/kg) supplement group (n = 48 cases). Patients' outcomes were evaluated using the Glasgow Outcome Scale. Serum levels of norepinephrine, cortisol, interleukin-6, C-reactive protein, neuron-specific enolase, and S100β were determined using enzyme-linked immunoassay. The cognitive function of patients was assessed using the Mini-Mental State Exam and Montreal Cognitive Assessment tests. DEX supplementation during anesthesia reduced adverse reaction, surgical stress, and attenuated cognitive impairment after extubation in IA patients' postintracranial interventional embolization. Our study demonstrated that employing DEX as supplementation during anesthesia could effectively reduce surgical stress and improve cognitive function, ultimately improving patients' recovery from intracranial interventional embolization.
