Design outcomes

Primary

Measure	Time frame
Time to onset of induction of general anesthesia as recorded by time of cessation of voluntary finger tapping, the time of loss of eyelash reflex, the time of establishment of regular breathing and the time of return of conjugate gaze.Timepoint: Since primary outcome is the time to onset of anesthesia derived from various indicators, the time of assessment cannot be specified as it may vary from subject to subject. The various indicators will be continuously looked for and the time noted.	—
