Relationship between Abdominal Circumference and Incidence of Hypotension during Cesarean Section under Spinal Anesthesia

Figure 1

Mean arterial pressure from baseline until 10 minutes after spinal anesthesia. Data are mean ± SD of mean arterial pressure. Data were analyzed using repeated-measure ANOVA. T0 = baseline mean arterial pressure before spinal anesthesia and T1–T10 = time after spinal anesthesia at 1-minute interval. AC = abdominal circumference; value < 0.05 between the smaller and larger AC groups.
