Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Group 1
Traditional deep extubation at 1.5 minimum alveolar concentration (MAC)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Extubation Success
Time Frame: Immediately after extubation

Maintenance of spontaneous ventilation without pathologic airway response such as laryngospasm.

Ventilation monitored in a standard manner, using chest wall movement, capnography, reservoir bag movement, condensation of anesthetic mask and auscultation.
Immediately after extubation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Anesthetic Vapor Concentration at Extubation
Time Frame: At the time of extubation
Percent of end-tidal sevoflurane at extubation
At the time of extubation

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Breath-holding
Time Frame: Prior to extubation
Measurement tool: Capnogram
Prior to extubation
