Objective:To assess the characteristics of the wake-up test during compound propofol-remifentanil infusions and sevoflurane inhalation for posterior spinal infusion(PSF)surgery.Methods:Twenty patients with scoliosis and candidates for PSF surgery were studied.After an i.v.bolus of remifentanil 1μg/kg
anesthesia was induced with propofol and atracurium.During maintenance
all patients received infusion of remifentanil 0.2μg/(kg·min)and propofol 50μg(kg·min)and inhalation of 2%sevoflurane.Atracurium was given to maintain the required surgical relaxation.At the surgeon’s request
all infusions were discontinued.Patients were asked to move their hands and feet.Time from anesthetic discontinuation to spontaneous ventilation(T

)
and from then until movement of the hands and feet (T

)
its quality and hemodynamics were recorded.Results:T
1
and T
2
were(4.1±2.0)minutes and(4.5±2.2)minutes
respectively. Quality of wake-up test reached satisfactory or good standard in 18 patients.Conclusion:wake-up test can be conducted fast and safely with propfol and remifentanil compound inhalation sevoflurane.
