No, I did NOT mean per minute. Ketamine dose for induction of unconsciousness/general anesthesia is 0.5-1.0 mg/kg as a bolus push over a few seconds. Ketamine comes as 100mg/cc and 10mg/cc: I always used the 10mg/cc formulation IV because it was easier to draw up the precise dose I wanted. Loss of consciousness takes 30 seconds to 1 minute for most people. I never used ketamine drips during anesthesia because it was just one more thing to have to track. Boluses every 30-60 minutes sufficed.

For IM use in children and patients with no venous access, induction of general anesthesia is achieved with a dose of 5-10mg/kg. Here, the 100mg/cc formulation is superior since the volume to be injected is 1/10 that required with the 10mg/cc version.
