Core Tip
Core Tip: This meta-analysis assessed the effectiveness of dexmedetomidine (DEX), a selective alpha-2 adrenergic receptor agonist, as a sedative agent in flexible bronchoscopy. Compared with other sedative and analgesic regimens, DEX notably reduced the risk of hypoxemia and tachycardia, while mildly improving patient and physician satisfaction. Although extra sedation was administered where necessary, the overall safety profiles were favorable. These findings suggest that DEX is a promising option for patients with compromised respiratory capacity, providing enhanced safety and tolerability during bronchoscopy.
