Remifentanil
"According to previous patient's response, the investigators will allocate the effect site concentration of remifentanil of next patient during double lumen tube intubation. For this allocation of dose of remifentanil the investigators use up-and-down method.~For the first patient, the dose of remifentanil would be fixed at 6.0 ng/ml which we predict as EC50. And, step size of dose is 0.5ng/ml."
