为了降低妊娠高血压产后高血压的发生率 ,依据客观因素设立观察组与同期对照组及历史对照组 ,3组进行对比 ,经统计学处理 ,论证妊娠高血压产后血压转归与围孕产期干预的关系。结果 :观察组和对照组对比 ,观察组产后高血压遗留率显著低于同期和历史对照组 (P<0 .0 1)。同时 ,妊娠高血压发生率、妊高征程度、围产期合并症发生率、围产儿死亡率等项 ,观察组均低于同期对照组 (P<0 .0 5 )。同期对照组与历史对照组对比 ,历史对照组产后高血压遗留率显著高于同期对照组 (P<0 .0 1)。其余项目无统计学意义。对围孕产妇给予妊娠高血压的早期预测、产前及产后干预 ,能够有效地降低妊娠高血压产后高血压的遗留率。同时 ,还可降低妊娠高血压的发生率 ,减轻妊高征程度 ,降低围产期合并症和围产儿死亡率 In order to reduce the incidence of postpartum hypertension in pregnancy-induced hypertension, the observation group and the control group and the historical control group were set up according to the objective factors. The three groups were compared. After statistical treatment, the post- Interventions. Results: Compared with the control group, the residual rate of postpartum hypertension in the observation group was significantly lower than that in the same period and the historical control group (P <0.01). At the same time, the incidence of pregnancy-induced hypertension, pregnancy-induced hypertension, the incidence of perinatal complications, perinatal mortality and other items were lower in the observation group than in the control group (P <0.05). Compared with the historical control group in the same period, the history of postpartum hypertension in the historical control group was significantly higher than the control group (P <0. 01). The remaining items were not statistically significant. The early prediction of pregnancy-induced hypertension in pregnant women, prenatal and postnatal intervention, can effectively reduce the pregnancy-induced hypertension postpartum hypertension. At the same time, can also reduce the incidence of pregnancy-induced hypertension, reduce the incidence of pregnancy-induced hypertension, reduce perinatal complications and perinatal mortality
