Background: Assessment of vocal cord movements following total thyroidectomy diagnoses recurrent laryngeal nerve injury. Use of videoscope along with sedatives may blunt hemodynamic responses seen with the conduct of direct laryngoscopy for assessing vocal cord mobility. Aims: The primary objective of this study was to assess changes in mean arterial pressure (MAP) during vocal cord assessment following total thyroidectomy using video laryngoscope, with and without the use of dexmedetomidine as an adjunct. Secondary objectives included assessment of changes in heart rate (HR), patient reactivity score along with ease of laryngoscopy and vocal cord visibility. Settings and Design: This randomized, prospective, unblinded study was conducted in 54 patients at a tertiary care center. Materials and Methods: Group D received dexmedetomidine 0.5 μg/kg, once the thyroid was removed. Group S did not receive dexmedetomidine. Hemodynamic response at extubation, patient reactivity, ease of laryngoscopy, and ease of vocal cord assessment were noted. Statistical Analysis Used: Chi-square test and Independent t-test. Results: Baseline HR, systolic blood pressure (SBP), and MAP were comparable between the groups. However subsequently, Group D had significantly lower HR and SBP at the time of extubation and at 3 and 6 min later. MAP at extubation and at 3 min later was comparable, but at 6 min, Group D had significantly lower values. In both groups, patient reactivity scores, ease of laryngoscopy, and vocal cord visibility were comparable (P > 0.05). Conclusion: Dexmedetomidine 0.5 μg/kg when used as an adjunct clinically improved conditions for assessing vocal cord mobility with significant attenuation of associated hemodynamic responses.
