Cerebral Blood Flow Velocity with Induction Dose of Intravenous Anesthetics

Cerebral Blood Flow Velocity with Induction Dose of Intravenous Anesthetics

No studies are available to compare directly the changes of cerebral blood flow (CBF) by induction doses of thiopental, propofol, midazolam and ketamine. We hypothesized that CBF would decrease in the order of thiopental, midazolam, and propofol, but increase with ketamine at induction of anesthesia. The present study compared the change of CBF with induction doses of these anesthetics by measuring CBF velocity (CBFV) using Transcranial Doppler.
