Fig 1 Uterine artery flows vary with fetal cardiac surgery. A representative plot from one animal shows uterine artery flow of the operated horn throughout the study period. Surgical manipulations during the experimental period are indicated by arrows. The typical range of uterine artery flows was between 300 and 500 mL/minute throughout the entire surgical period, indicated by dashed horizontal lines. Open squares refer to time points of measurement.

Fig 3 Effects of sternotomy (A), cannulation (B), and initiation of bypass (C) on fetal arterial gases before and after these surgical events are shown. Values shown are the mean ± SD. Closed squares and diamonds refer to data points.

Fig 4 Effects of sternotomy (A), cannulation (B), and initiation of bypass (C) on maternal arterial gases before and after surgical manipulations of the fetus are shown. Values shown are the mean ± SD. Closed squares and diamonds refer to data points.

Fig 5 Effects of sternotomy (A), cannulation (B), and initiation of bypass (C) on maternal mean arterial pressure and heart rate are shown. The values shown are the mean ± SD.
