The purpose of this report was to investigate the potential usefulness of average mean arterial pressure, maximal mean arterial pressure, and maximal diastolic pressure during the second trimester in predicting the development of eclampsia in 207 nulliparas and 20 multiparas with eclampsia. In the nulliparas, both the mean arterial pressure and the maximal mean arterial pressure during the second trimester were greater than or equal to 90 mm Hg in 22% and 34% of the patients, respectively. For the multiparas, the percentages with greater than or equal to 90 mm Hg were 30% and 35%, respectively. Only 8.7% of nulliparas with eclampsia had a maximal diastolic pressure during the second trimester greater than or equal to 80 mm Hg and no patient had a diastolic pressure of greater than or equal to 90 mm Hg. A review of the literature suggests that the mean arterial pressure observed during the second trimester has poor predictive value for future development of preeclampsia-eclampsia. We conclude that there is no correlation between second-trimester blood pressure recordings and subsequent eclampsia.
本报告旨在研究孕中期平均动脉压、最大平均动脉压和最大舒张压对207例初产妇和20例经产妇子痫发生发展的预测价值。在初产妇中，孕中期平均动脉压和最大平均动脉压分别有22%和34%的患者大于或等于90 mmHg。经产妇中，大于或等于90 mmHg的比例分别为30%和35%。初产妇子痫患者中只有8.7%的孕中期最大舒张压大于或等于80 mmHg，没有患者舒张压大于或等于90 mmHg。文献综述表明，孕中期观察到的平均动脉压对先兆子痫-子痫的未来发展预测价值较差。我们得出结论，孕中期血压记录与随后的子痫之间没有相关性。
