Comparison of remifentanil concentrations with and without dexmedetomidine for the prevention of emergence cough after nasal surgery: A randomized double-blinded trial

Preventing emergence cough after nasal surgery is critical. Emergence cough can provoke immediate postoperative bleeding, which leads to upper airway obstruction. In the present study, we compared the effect-site concentration (Ce) of remifentanil to prevent emergence cough after propofol anesthesia for nasal surgery when remifentanil was or was not combined with dexmedetomidine.
