摘要
目的 研究正常妊娠及妊高征患者动态血压变化。 方法 对 38例正常妊娠孕妇分别于妊娠 18～ 2 0、2 8～ 30、38～ 40周及 36例妊高征患者进行了 2 4h动态血压监测。 结果 正常妊娠孕妇随孕周增加 2 4h平均血压逐渐升高 ,正常妊娠孕妇 3个时期分别有 84.2 %、86 .8%及 86 .8%血压呈昼夜变化节律 ,表现为日间血压升高 ,夜间血压减低 ,昼夜平均血压差分别为 (16 .3± 4.1) %、(14.1± 3.2 ) %及 (15 .2± 3.7) %。中、重度妊高征患者 2 4h平均血压、血压负荷及血压节律异常率均明显高于轻度妊高征及各期正常妊娠 ,昼夜平均血压差则明显减低。 结论 正常妊娠血压有昼夜节律变化 。
Objective To study the blood pressure changing patterns in normal pregnancy and pregnancy induced hypertension(PIH). Methods 24 hour ambulatory blood pressure monitoring (ABPM) were performed in 38 cases of normal pregnancy and 36 cases of PIH during 18～20,28～30 and 38～40 gestational week. Results The 24 hour mean blood pressure were increased with pregnancy advanced. In normal pregnancy, a typical circadian rhythm of blood pressure pattern was shown that it increases during the day and decreased during the night with the disparity of (16.3± 4.1)%, (14.1±3.2)% and (15.7±2.0)% in three different gestational week respectively. In moderate and severe PIH, the 24 hour mean blood pressure,blood pressure load and the frequence of abnormal rhythm were significantly higher than those in mild PIH and normal pregnancy, while the disparity between day and night blood pressure was lower. Conclusion The blood pressure patterns show a typical circadian rhythm in most normal pregnancy. The more severe the PIH is, the higher rate of abnormal blood pressure rhythm occured.
