Clinical Analysis Of The Causes For 98 Cases Of Stillbirth

Objective: The purpose of this study was to investigate the incidence and causes of stillbirth,which will provide a basis for developing measures to reduce the occurrence of stillbirth.Methods: 1.The clinical data of 98 women and 99 fetuses(one case was twins)diagnosed stillbirth in our hospital from January 1,2006 to December 31,2015 were collected,including maternal age,parity,adverse pregnancy history,maternal diseases,fetal anomaly or not,birth weight and gestational age of stillbirth,umbilical cord and placental pathology.To analyze the incidence of stillbirth.2.Pursuant to Williams Obstetrics(24th edition),the causes of stillbirth were divided into the following eight categories: obstetric complications,placental abnormalities,fetal malformations,infection,umbilical cord abnormalities,hypertensive disorders,medical complications and undetermined.To analyze the causes for 98 cases of stillbirth,and calculate the constituent ratio of each cause.3.98 cases of stillbirth were divided into 3 groups,group A(20 ~ 27 + 6 week),group B(28 ~ 36 + 6 week),and group C(37 ~ 42 weeks).Compared the differences of maternal age,parity and various causes among the group A,B,C.4.Statistical methods: Using SPSS 19.0 software package for the statistical data and analysis.For count data,rates among groups were compared by Fisher's exact test,?2 test was used for the comparison between groups.P <0.05 was considered statistically significant.Results: 1.The delivered number in our hospital from Jan.1,2006 to Dec.31,2015 was 14,348,including 98 cases of stillbirth,the incidence of stillbirth was 6.8 ‰.2.The causes and the constitution of stillbirth were: 31 cases of hypertensive disorders(31.6%),25 cases of medical complications(25.5%),20 cases of undetermined reasons(20.4%),18 cases of abnormal cord(18.4%),14 cases of infection(14.3%),11 cases of abnormal placenta(11.2%),9 cases of obstetric complications(9.2%),7 cases of fetal malformations(7.1%),of which 30 cases of stillbirth had two or more reasons.3.The maternal age and parity in the group A,B,C had no significant difference(P> 0.05).The infection among group A,B,C had significant difference(P <0.05),the infection in group B(21.3%)was significantly higher than that in group A(2.4%)(P <0 05);The placental abnormalities among group A,B,C had significant difference(P <0.05),but there was no significant difference between the two groups(P> 0.05);The other causes(obstetric complications,fetal malformation,umbilical cord abnormalities,hypertensive disorders,medical complications and undetermined)among the group A,B,C had no significant difference(P> 0.05).Conclusions:1.The main causes of stillbirth were serious hypertensive disorders complicating pregnancy,diabetes mellitus type 2 and gestational diabetes mellitus which was not well controlled,and the most of cases had several reasons.2.Compared with the second trimester of pregnancy,infection was more likely to cause the stillbirth in late pregnancy.3.There was a little cases with placental pathology and autopsy of fetuses.There was rare genetic examination after birth.The real time of fetal death was undetermined.
