| Abstract | ||||
| Background: Stimulation of various sites, from the nasal mucosa to the diaphragm, can evoke laryngospasm. To reduce airway reflexes, tracheal extubation should be performed by special technique or with drugs that do not depress ventilation. However, tracheal extubation during rhinoplasty may be difficult because of the aspiration of blood and the possibility of laryngospasm. Dexmedetomidine has sedative and analgesic effects, without affecting respiratory status. Objectives: To evaluate the effects of dexmedetomidine on airway-related complications during emergence from general anesthesia (GA) in nasal and paranasal surgeries. Patients and Methods: This prospective randomized clinical study was included 90 patients of both sexes, admitted for elective nasal and paranasal sinus surgery. They were randomly allocated into three groups 30 patients each, Group A: Standard awake extubation technique. Group B: fully awake “no stimulation extubation” technique. Group C: Dexmedetomidine–group, who received intravenous (I.V) dexmedetomidine 0.5-1 μg/kg bolus in 100 ml of normal saline over 10 minutes before the end of surgery by 10 minutes, The dexmedetomidine bolus was followed by 0.2 μg/kg/hr which was stopped immediately when extubation was done. Results: The following parameters were assessed between the three groups: hemodynamics, airway-related complications, extubation time. Group C: was associated with a significant increase in extubation quality compared with group A and group B regarding hemodynamics, airway-related complications, extubation time. Conclusion: This study showed that the dexmedetomidine group associated with minimal circulatory reflexes and airway-related complications further to the advantage of short extubation time compared with the “no stimulation” extubation technique. | ||||
