目的：探讨重度妊高征发生时间与母儿预后的关系。方法：将108侧重庆妊高征孕产妇的114例围产儿分成4组进行临床分析。结果：孕33周前围产儿死亡率明显高于其它发病各组；新生儿窒息率以孕33～36(+6)周发病组最低；孕37周前低于孕龄儿发生率明显高于孕37周后发病组。结论：重度妊高征发生越早，母儿预后越差，同时妊高征时，胎肺有提前成熟倾向，孕龄越过37周后新生儿窒息率明显增加，如病情严重，以孕33～36(＋6)周终止妊娠为宜。
Objective: To investigate the relationship between the occurrence of severe PIH and the prognosis of maternal and child. Methods: One hundred and seventy four hundred pregnant women with PIH were divided into 4 groups for clinical analysis. Results: The incidence of perinatal mortality was significantly higher 33 weeks before pregnancy than in other groups. The incidence of neonatal asphyxia was the lowest in 33-36 (+6) weeks of pregnancy and lower than that in gestational age 37 weeks 37 weeks after the onset of disease group. Conclusions: The earlier the severe PIH is, the worse the prognosis is. In the meanwhile, the fetal lung has the tendency of maturing prematurely. When the gestational age exceeds 37 weeks, the neonatal asphyxia rate obviously increases. For example, 36 (+6) weeks of termination of pregnancy is appropriate.
