目的探讨围产儿死亡原因及相关因素。方法回顾性分析北京军区总医院2009-2015年围产儿死亡评审资料及病例,对围产儿及孕产妇的基本情况及相关因素进行统计和分析。结果 12009-2015年围产儿死亡总数74例,平均围产儿死亡率为4.34‰,7年间年围产儿死亡率保持逐年下降趋势。在围产儿死亡病例中,死胎48例,7 d内新生儿死亡26例。2孕产妇<25岁及>35岁围产儿死亡率明显增高(P<0.01),随孕周增加围产儿死亡率明显下降(P<0.01),出生体重<2 500 g围产儿死亡率为4.32%是正常体重儿的33.23倍。3在7 d内新生儿死亡病例中,早产儿死亡16例,足月新生儿死亡10例;其中自发性早产占主要因素(23.07%),其次为出生缺陷(19.23%)。医源性早产中,出生缺陷和严重内外科合并症为主要因素(各占11.54%)。4死胎的前三位死因分别为脐带因素(35.41%)、出生缺陷(20.83%)、妊娠合并症及并发症(18.76%)。5围产儿死亡相关影响因素为孕妇接受产检次数。本市居民组平均产检次数为(8.53±2.67)次,外来居民组为(5.84±4.52)次,两组差异有统计学意义(P<0.05)。结论提高孕期保健意识、加强产前检查及孕期保健、预防并积极干预早产降低早产发生率、尽早发现并积极治疗各种妊娠并发症合并症、利用产前诊断技术尽早发现胎儿畸形及时终止妊娠、提高助产技术是降低围产儿死亡率的主要措施。 Objective To investigate the causes and related factors of perinatal death. Methods The data and cases of perinatal death assessment from 2009 to 2015 in General Hospital of Beijing Military Region were retrospectively analyzed. The basic conditions and related factors of perinatal and maternal women were statistically analyzed. Results The total number of perinatal deaths in the period from 12009 to 2015 was 74 and the average perinatal mortality rate was 4.34 per thousand. The annual perinatal mortality rate kept decreasing year by year for a period of 7 years. Among the perinatal deaths, 48 ​​were stillbirths and 26 were neonatal deaths within 7 days. Perinatal mortality rates of pregnant women <25 years old and> 35 years old were significantly higher (P <0.01). Perinatal mortality was significantly decreased with gestational age increased (P <0.01), and perinatal mortality with birth weight <2 500 g was 4.32 % Is 33.23 times the normal weight of children. 3 Among the neonatal deaths within 7 days, 16 were premature children and 10 were full-term newborns. Among them, spontaneous preterm birth accounted for 23.07%, followed by birth defects (19.23%). In iatrogenic preterm labor, birth defects and severe internal and external complications were the major factors (11.54% each). The first three causes of stillbirth were umbilical cord factors (35.41%), birth defects (20.83%), pregnancy complications and complications (18.76%). 5 Perinatal mortality related factors for pregnant women accept the number of births. The average number of times of quarantine in residents in this Municipality was (8.53 ± 2.67) times and that of non-resident residents was (5.84 ± 4.52) times, there was a significant difference between the two groups (P <0.05). Conclusion To improve the awareness of health care during pregnancy, to strengthen prenatal care and prenatal care, prevention and intervention of preterm birth to reduce the incidence of preterm birth, early detection and treatment of complications of pregnancy complications, prenatal diagnosis of fetal malformations as early as possible and timely termination of pregnancy, Improving midwifery technology is the main measure to reduce perinatal mortality.
