A Comparative Study of Intravenous Dexmedetomidine‑versus Propofol‑based Sedation for Awake Fiberoptic Intubation Along with Airway Blocks in Cervical Discectomy Patients

Background: In unstable cervical spine, optimal intubation positioning of the patient may be unsafe. Awake intubation is indicated, which is rendered more comfortable by light sedation. Aims and Objectives: This study compared intravenous dexmedetomidine versus propofol‑based sedation for awake fiberoptic intubation along with airway blocks. Materials and Methods: 100 ASA I and II patients with cervical PIVD are recruited for this study. Vital parameters such as heart rate, systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP), and SPO2 were monitored at regular intervals. Patient sedation score, endoscopy score, intubation score, post‑intubation conditions, and discomfort score were also recorded. Results: There was no statistically significant difference between the two groups with respect to SBP, DBP, mean blood pressure (MBP), heart rate (HR), and SPO2. Conclusions: Dexmedetomidine appeared to offer better patient tolerance, better preservation of a patent airway, and spontaneous ventilation.
