三十年子的变化趋势

The Changing Trend of Eclampsia During 30 years

目的 探讨 30年来我院子的变化特点。 方法 回顾性分析 1971～ 2 0 0 0年期间发生的 98例子病例。 结果 子的发生率由 70年代 0 .3%降至 90年代 0 .1% (P<0 .0 1) ,产前子占子总数的比率由 70年代 5 2 .1%降至 90年代 2 6 .3% (P<0 .0 5 ) ,产后子由 70年代 2 0 .8%升至 90年代 47.4% (P<0 .0 5 )。围产儿死亡率由 70年代 2 0 3.7‰下降至 90年代 10 0 .0‰。三个年代子所致孕产妇的死亡占同期子的比率依次为 4.2 %、6 .5 %、5 .3% (P>0 .0 5 )。 结论 30年来子的发生率明显下降 ,子类型构成比发生明显变化 ,产前子减少 ,产后子相对增多 ,子患者的围产儿死亡率逐渐下降 ,子致孕产妇死亡率未降低。

Objective To investigate the changing trend of eclampsia in our hospital during 30 years. Methods We retrospectively analysed 98 cases of eclampsia from 1971 to 2000. Results The incidence of eclampsia fell from 0.3% in the 1970s to 0.1% in the 1990s (P<0.01),The incidence of antepartum eclampsia fell from 52.1% in the 1970s to 26.3% in the 1990s (P< 0.05), postpartum eclampsia rose from 20.8% in the 1970s to 47 4% in the 1990s (P<0.05). The perinatal mortality fell from 203.7‰ in the 1970s to 100.0‰ in the 1990s. The ratio of death of eclampsia to eclampsia during same period was 4.2% in 1970s, 6.5% in 1980s and 5.3% in 1990s (P>0.05). Conclusions The incidence of eclampsia has fallen significantly during 30 years. The composition of eclampsia has changed significantly, antepartum eclampsia decreased and postpartum eclampsia increased. The perinatal mortality has fallen. The death ratio of women with eclampsia hasn't fallen.
