分析妊娠晚期发生羊水过少的相关因素

Analysis of the factors of amniotic fl uid in the late trimester of pregnancy

目的分析妊娠晚期发生羊水过少相关因素。方法选取2013年3月～2015年3月在我院就诊的羊水过少分娩孕妇1489例，对其相关资料做回顾性分析。结果本研究中羊水过少的出现率为7．59％（113／1489），显著高于国内报道的0．14％～4．10％和国外报道的0．15％～5．15％；孕周在40周以上的孕妇出现羊水过少几率与孕周在42周以上的孕妇出现羊水过少几率相比，差异无统计学意义（P〉0．05），与孕周在40周以下的孕妇出现羊水过少几率比较，差异有统计学意义（P〈0．05）；36岁以上孕妇的羊水过少几率显著增高，同36岁以下的各组对比，差异均有统计学意义（P〈0．05）；36岁以下各组间的羊水过少出现率比较，差异无统计学意义（P〉0．05）；脑力劳动组同体力劳动组对比，差异有统计学意义（P〈0．05），脑力劳动组同待业组对比，差异有统计学意义（P〈0．05），体力劳动组同待业组对比，差异无统计学意义（P〉0．05）。结论妇女的适龄生育、劳逸结合、情绪调节、压力缓冲、身心放松，注意饮水，定期产检、妊娠的适时终止可能可以降低羊水过少发生率。

Objective To analyze and explore the related factors of oligohydramnios in late pregnancy. Methods 1489 maternal women with oligohydramnios treated in our hospital during 2013.3 to 2015.3 were selected and their data was retrospectively analyzed. Results In our research, the incidence of oligohydramnios was 7.53% （112/1489）, significantly higher than 0.14% ~ 4.10% of Domestic coverage and 0.15% ~ 5.15% of foreign coverage; The incidence of oligohydramnios in patients with more than 40 gestational weeks has significantly increased, compared to that of patients with more than 42 gestational weeks, the difference was not statistically significant （P〉0.05）, compared to that of patients with less than 40 gestational weeks, the difference was statistically significant （P〈0.05）. The incidence of oligohydramnios in patients older than 36 years has significantly increased, compared to groups within patients younger than 36 years, the differences were all statistically significant （P〈0.05）. There was no statistically significant difference among groups within patients younger than 36 years （P〉0.05）. The difference between mental group and manual labor group was statistically significant （P〈0.05）, the difference between mental group and unemployed Group was statistically significant （P〈0.05）, the difference between manual labor group and unemployed Group was not statistically significant （P〉0.05）. Conclusion The appropriate reproductive age, work combined rest, emotion regulation, stress buffer, relaxation, attention to drinking water, regular cheek-ups, timely termination of pregnancy may reduce the incidence of oligohydrarnnios.
