Individual responses to endotracheal intubation according to the up-and-down method. A higher effect-site concentration of remifentanil was given to the next patient when a patient showed positive hemodynamic response during endotracheal intubation (empty triangle). A lower effect-site concentration of remifentanil was given to the next patient when a patient showed negative hemodynamic response during endotracheal intubation (filled triangle)
