Fifty female patients who were selected to schedule for mammary gland tumor excision surgery, were divided into 2 groups(n=25 in each group): group A: received propofol's half-effective concentration at 3.0 μg/ml in Marsh model by TCI; group B: received propofol's half-effective concentration at 4.0 μg/ml in Marsh model by TCI. All patients were given remifentanil in Minto model by TCI after being given propofol which reached the balance between effect-site concentration and blood plasma concentration. The target concentration of remifentanil was determined by a modification of Dixon's up-and-down method. Laryngeal mask insertion was attempted after 10 mins, the insertion condition and success rate were observed, then the suitable target concentration of remifentanil(ECe50) were calculated.
