目的探讨羊水过少发生率升高的影响因素。方法采用回顾性分析方法,对2005年8月~2008年8月在我院分娩产妇羊水过少的261例相关资料进行分析。结果3年来我院分娩产妇羊水过少发生率为5.0%,与国内报导的0.4%~4.0%和国外报道的0.5%~5.5%基本相符;羊水过少高发于40孕周后,孕周≥40周羊水过少的发生率明显高于<40周(P<0.05);孕妇年龄越大,羊水过少的发生率越高,孕妇年龄>33岁与<30岁比较,差异有统计学意义;脑力劳动者比体力劳动者羊水过少的发生率高。结论羊水发生率与孕周、受孕年龄、体力劳动还是脑力劳动有关。
Objective To investigate the factors that influence the incidence of oligohydramnios. Methods Retrospective analysis was used to analyze 261 cases of oligohydramnios in our hospital from August 2005 to August 2008. Results The prevalence of oligohydramnios in our hospital was 5.0% within 3 years, basically consistent with the 0.4% -4.0% of the reported in the country and 0.5% -5.5% of the foreign reports. In oligohydramnios after 40 weeks of gestation, gestational weeks ≥ The incidence of oligohydramnios at week 40 was significantly higher than that at <40 weeks (P <0.05). The higher the age of pregnant women was, the higher the incidence of oligohydramnios was. The mean age of pregnant women was 33 years old and <30 years old, the difference was statistically significant ; Mental workers than manual labor, oligohydramnios high incidence. Conclusion Amniotic fluid incidence and gestational age, age of conception, manual labor or mental labor.
