Table 1. Comparison of Baseline FV^MCAbetween Two Anesthetic Conditions

Values are expressed as absolute velocities (mean ± SD).

*Study 1 = N²O alone vs.  N²O added with propofol. Study 2 = propofol alone vs.  N²O added to propofol.

†Significance levels of differences between the two anesthetic conditions.

FV^MCA, blood flow velocity at the middle cerebral artery.
