<prompt> Inducing dose of Propofol in adults1 mgkg2 mgkg3 mgkg5 mgkg  <response>: B 2 mgkg The dose of Propofol is 2-2.5 mgkg for induction. The lower dose should be used in the elderly. The effective blood concentration for anaesthesia ED 90 - the dose at which the effect is seen for 90 of patients is 3.4 mgmL when used with 67 nitrous oxide. Sedation may be produced with a 0.2 mgkg bolus dose intravenously or an infusion of 2 mgkgh, which produces a blood concentration of about 2 mgmL. Co-induction with either an opioid or midazolam enables the induction dose and initial target level for TCI to be reduced. Myoclonic movements are common on induction, especially with slow injection. Emergence is more rapid than with thiopentc , with less hangover.
