Targeting smooth emergence: the effect site concentration of remifentanil for preventing cough during emergence during propofol-remifentanil anaesthesia for thyroid surgery

We found that the EC95 of effect site concentration of remifentanil to suppress coughing at emergence from anaesthesia was 2.14 ng ml−1. Maintaining an established Ce of remifentanil is a reliable method of abolishing cough and thereby targeting smooth emergence from anaesthesia.
