目的探讨低出生体质量(LBW)儿适宜的分娩方式及适时终止妊娠的时机。方法选取自2010年1月到2015年1月于我院分娩的6244例新生儿作为研究对象,通过孕产妇管理系统获得相关病史资料,统计低出生体重儿的发生情况、分娩方式和终止妊娠的时机。结果统计结果显示低出生质量儿的发生率为7.43%(464/6244),其中早产低出生体质量儿占全部早产儿的60.56%(344/568),足月低出生体质量儿占全部足月儿的2.11%(120/5676),两者比较有统计学差异(P﹤0.05);低出生体质量儿的刨宫产的比率要高于正常体重儿的比率(P﹤0.05)。在低出生体质量儿中的新生儿窒息率和新生儿死亡率上,阴道分娩者比刨宫产分娩者明显低;但是随着孕周的增加低出生体质量儿的新生儿窒息率和死亡率会逐渐降低。结论为了减少低出生体质量儿的发生,对于有早产迹象的胎儿和孕妇,应积极为其做个体化分析,尽可能延长其孕周至34w之后再行终止妊娠;根据孕妇和胎儿的具体情况制定合理的分娩方式可以显著提高新生儿的存活率。
Objective To investigate the appropriate mode of delivery and the timing of termination of pregnancy in low birth weight children (LBW). Methods Six thousand four hundred twenty-four newborns who were delivered in our hospital from January 2010 to January 2015 were selected as research objects. Relevant medical history data were obtained through maternal management system. The incidence of low birth weight infants, mode of delivery and termination of pregnancy The timing. The results showed that the incidence of low birth weight children was 7.43% (464/6244), of which premature low birth weight children accounted for 60.56% of all preterm children (344/568), full-term low birth weight children accounted for full foot 2.11% (120/5676) in infants, the difference was statistically significant (P <0.05); the rate of placenta producing children with low birth weight was higher than that of normal infants (P <0.05). Neonatal asphyxia and neonatal mortality in low-birth-weight children were significantly lower in vaginal delivery than those in placenta hirsutum; however, asphyxia and death of newborns with low birth weight were associated with an increase in gestational age The rate will gradually decrease. Conclusion In order to reduce the incidence of low birth weight infants, fetuses and pregnant women with signs of preterm birth should be actively analyzed individually to prolong their gestational age up to 34 weeks before termination of pregnancy. According to the specific conditions of pregnant women and fetuses Reasonable mode of delivery can significantly improve the survival rate of newborns.
