NCT01974648

Brief Summary

The aims of this study were to determine the clinically required concentration of propofol for LMA Supreme insertion, and to examine to what extent remifentanil reduces the dose of propofol and improves conditions for it's insertion.

Outcome Measures

Primary Outcomes (1)

  • The concentration of propofol with and without remifentanil for insertion of the SLMA

    Comparison of he concentration of propofol with and without remifentanil for insertion of the SLMA

    at insertion of SLMA

Secondary Outcomes (5)

  • changes in Systolic Blood Pressure, Diastolic Blood Pressure and Heart Rate

    basal and every 3 minutes until 6 minutes after insertion of the SLMA

  • BIS

    before and after SLMA insertion(every min until min 6)

  • Fibrescope evaluation

    after SLMA insertion

  • blood pressure(Hypertension or hypotension)

    before and after SLMA insertion(every min until min 6)

  • heart rate (tachycardia or bradycardia)

    before and after SLMA insertion(every min until min 6)

Study Arms (2)

propofol

ACTIVE COMPARATOR

In control group, propofol concentrations will start at 4 μg ml-1, with 0,5 μg ml-1 as the step size, with the coadministration of saline.

Drug: propofol

propofol and remifentanil

EXPERIMENTAL

In propofol-remifentanil group, propofol + remifentanil at a target-controlled infusion 5 ng/mL will be coadministered.

Drug: propofol and remifentanil

Interventions
