Blood pressure was monitored continuously and intraarteriously for 24 hours in healthy and pre-eclampsia pregnant women. The monitoring system almost excluded sources of error. The 24-hours-rhythm revealed a blood pressure decrease of about 20 Torr systolically and diastolically between 2.00 a.m. and 5.00 a.m. in normal pregnancy. This decrease after midnight was diminished in mild cases of pre-eclampsia. Hypertensive peaks were present after midnight in severe pre-eclamptic toxemia even under medication. Measuring of the blood pressure in pre-eclampsia patients during nighttime from 0.00 a.m. until 5.00 a.m. seems to be advisable in order to identify unstabilized hypertensive peaks.
对健康孕妇和先兆子痫孕妇进行了24小时的动脉内连续血压监测。该监测系统几乎排除了误差来源。24小时节律显示，正常妊娠时，凌晨2点至5点期间收缩压和舒张压均下降约20托。子痫前期轻症患者午夜后的这种下降有所减少。即使在用药情况下，重度子痫前期毒血症患者午夜后仍会出现高血压峰值。为了识别不稳定的高血压峰值，建议在夜间凌晨0点至5点期间对子痫前期患者进行血压测量。
