Population based, prospective study of the care of women with epilepsy in pregnancy.

operating field impaired access to the patients. The radial pulse always disappeared before the femoral pulse, which always disappeared before the carotid pulse. The data were split into four subgroups: radial, femoral, and carotid pulses present (group 1), femoral and carotid pulses only (group 2), carotid pulse only (group 3), and radial, femoral, and carotid pulses absent (group 4). The figure shows the distribution of the systolic blood pressure in each of these groups. The reference lines in the figure at 80 mm Hg, 70 mm Hg, and 60 mm Hg represent the values that, according to the advanced trauma life support guidelines, the systolic blood pressure is expected to exceed for groups 1, 2, and 3 respectively. In group 1, 10/12 (83%) subjects had a systolic blood pressure < 80 mm Hg (mean 72.5 mm Hg (reference range 55.3-89.7 mm Hg)). In group 2, 10/12 (83%) subjects had a systolic blood pressure < 70 mm Hg (mean 66.4 mm Hg (50.9-81.9 mm Hg)). In group 3, none of the four patients had a systolic blood pressure > 60 mm Hg as predicted by the advanced trauma life support guidelines. And in group 4, 2/3 patients had a systolic blood pressure < 60 mm Hg as predicted by the advanced trauma life support guidelines. Comment
