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

Figure 2

Mean arterial pressure difference from baseline until 10 minutes after spinal anesthesia. The values were calculated as MAP at T1, T2, T3, …, T10 subtracted by MAP at T0. Data are mean ± SD of mean arterial pressure difference. 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.
