Administration of dexmedetomidine before end of surgery could reduce airway reflexes and hemodynamic changes during tracheal extubation. Compared with remifentanil alone, administration of dexmedetomidine in combination with remifentanil is effective in relieving cough and hemodynamic changes without inhibition of respiration. The purpose of this study was to investigate the effect of dexmedetomidine on the remifentanil concentration for the cough suppression during anesthetic emergence using the modified up-and-down method.
Dexmedetomidine or remifentanil are effective in attenuating cough during peri-extubation period after general anesthesia. The purpose of this study was to investigate the effect of dexmedetomidine on the remifentanil concentration for the cough suppression during anesthetic emergence.
