目的探讨极低出生体重儿发生的有关影响因素。方法分析66例极低出生体重儿的一般情况、产科及母孕期情况。采用多元逐步回归分析对66例极低出生体重儿母亲年龄、地域,多胎妊娠,孕周,胎盘早剥,胎膜早破,妊娠高血压综合征,母亲贫血,羊水异常,母亲心血管疾病等与极低出生体重的关系进行分析。结果孕周小于等于32周62.1%,胎膜早破51.5%,多胎妊娠31.8%,母亲贫血31.8%,妊娠高血压综合征24.2%,羊水异常13.6%,胎盘早剥9.1%,母亲心血管疾病4.5%。孕周,妊娠高血压综合征,羊水异常是极低出生体重发生的重要影响因素。结论加强孕期保健,早期诊断及防治妊娠期合并症及并发症有利于预防和减少极低出生体重儿的发生。
Objective To explore the influencing factors of very low birth weight infants. Methods 66 cases of very low birth weight children in general, obstetric and during pregnancy. Multivariate stepwise regression analysis of 66 cases of very low birth weight children mother age, geography, multiple pregnancy, gestational age, placental abruption, premature rupture of membranes, pregnancy-induced hypertension, maternal anemia, amniotic fluid abnormalities, cardiovascular disease, etc. The relationship with very low birth weight was analyzed. Results Week gestational age was less than or equal to 62.1% in 32 weeks, premature rupture of membranes was 51.5%, multiple pregnancy was 31.8%, maternal anemia was 31.8%, pregnancy induced hypertension syndrome was 24.2%, amniotic fluid abnormality was 13.6%, placental abruption was 9.1%, maternal cardiovascular disease 4.5%. Gestational gestational age, pregnancy-induced hypertension syndrome, amniotic fluid abnormalities are the important factors affecting the birth weight. Conclusion Strengthening pregnancy care, early diagnosis and prevention and treatment of complications and complications during pregnancy are helpful to prevent and reduce the incidence of very low birth weight infants.
