Comparison of Remifentanil With a Combination of Remimazolam and Dexmedetomidine for Awake Tracheal Intubation

Awake fiberoptic intubation (AFOI) requires airway surface anesthesia to inhibit pharyngeal reflex, glottis closure reflex, and cough reflex. Additionally, the use of sedative drugs can enhance patient comfort and tolerance, reduce anxiety, and eliminate harmful effects on systemic hemodynamics.The objective of this study is to compare the safety and efficacy of remifentanil alone versus a combination of dexmedetomidine and remifentanil for sedation during conscious tracheal intubation.
