Measured Baseline Values for Each Individual Chromophore for the Control Flap, Selective Arterial Occlusion Flap, Selective Venous Occlusion Flap, and Native Skin Groups^*

Group	Hbo2 (μM/liter)	Hb (μM/liter)	HbT (μM/liter)	Sto2 (%)
Control flap	67.93 ± 7.302	62.62 ± 6.077	130.5 ± 12.63	51.44 ± 2.041
Selective arterial occlusion flap	45.00 ± 2.989	52.47 ± 4.615	97.54 ± 7.325	46.06 ± 1.108
Selective venous occlusion flap	58.85 ± 7.813	59.16 ± 4.746	118.0 ± 11.59	48.77 ± 2.326
Native skin	61.00 ± 9.940	50.70 ± 4.449	112.0 ± 13.98	53.29 ± 2.160

^*Baseline values represent the average value for each chromophore measured during the 10-minute period (−10 minutes to 0 minutes), just before selective vascular occlusion in the experimental flap groups (selective arterial and selective venous occlusion flap groups). Statistical analysis was performed using a one-way analysis of variance with a Dunnett's posttest analysis allowing for a direct comparison of the baseline chromophore values between the control flap group and the three other groups (selective arterial occlusion flap, selective venous occlusion flap, and native skin groups).
