Conditions: Idiopathic Scoliosis
Keywords: intra operative neurophysiologic monitoring transcranial motor evoked potential anesthesia pulses
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 30
Healthy volunteers: no

Brief summary:
Test the hypothesis to recruit larger motor responses to transcranial stimulation.

Detailed description:
The study is designed to test the hypothesis that it is possible to recruit larger motor responses to transcranial stimulation by increasing the number of stimulating pulses under both baseline conditions and conditions of increased anesthetic suppression of the motor responses.

Arms:
arm 1: Transcranial motor evoked potentials are obtained under total intravenous anesthesia (TIVA) and again after desflurane at 3%, for at least 5 minutes.at two different time points. Each subject is his/her own control

Interventions: intervention 1: Desflurane
Intervention descriptions: intervention 1: None
