【摘要】目的 观察分析过期妊娠与新生儿窒息的相关性，总结其临床意义。方法 选取我站2008年10月至2010年10月80例孕周>41周的产妇，设为观察组，再选取同期80例孕周在37~40周的产妇作为对照组，对其临床病历资料进行回顾性分析，观察比较两组产妇的孕周、胎盘成熟度、羊水量、分娩方式及产程与新生儿窒息间的关系。结果 观察组的新生儿窒息率明显高于对照组(P<0.05)，具有统计学意义。观察组的孕周、羊水量、分娩方式及产程与新生儿窒息间有密切的关系(P<0.05)，具有统计学意义；胎盘成熟度与新生儿窒息间无明显关系(P>0.05)，无统计学意义。观察组的孕周越大，新生儿窒息率也增高，呈正相关；羊水量减少(羊水池在3cm以内)与新生儿窒息率呈正相关关系；各种分娩方式中以臀位阴道助产的新生儿窒息率最高，其次为胎吸、自然分娩、剖宫产；产程与新生儿窒息率直接也呈正相关的关系。结论 过期妊娠的产妇发生新生儿窒息，主要原因为营养缺乏或慢性缺血缺氧，因此需要加强产前的母婴监护，了解胎儿的宫内情况，适时给予终止妊娠，尽可能降低新生儿窒息率，保障目前安全。

【Abstract】Objective To observe the analysis of prolonged pregnancy and neonatal asphyxia correlation to summarize the clinical significance. Methods I stand from October 2008 to October 2010 80 cases of gestational age> 41 weeks of maternity, is set to the observation group, and then select the same period 80 cases of 37 to 40 weeks gestation in the mothers as a control group, the clinical medical records were retrospectively analyzed, observed and compared two groups of maternal gestational age, placental maturity, amniotic fluid, mode of delivery and birth process and the relationship between neonatal asphyxia. Results The rate of neonatal asphyxia was significantly higher (P <0.05), with statistical significance. Observation group, gestational age, amniotic fluid, mode of delivery and neonatal asphyxia and birth process between closely related (P <0.05), with statistical significance; placental maturity and neonatal asphyxia was no significant relationship (P> 0.05), not statistically significant. Observation group, the greater gestational age, neonatal asphyxia also increased, a positive correlation; amniotic fluid volume decrease (sheep pool in less than 3cm) and neonatal asphyxia were positively correlated; a variety of delivery methods in order to breech vaginal delivery of the newborn the highest rate of child suffocation, followed by vacuum extraction, natural childbirth, cesarean section; labor and neonatal asphyxia direct and positive correlation relationship ......
