目的探讨胎心监护基线变异静止型与胎儿宫内缺氧的关系。方法随机性选择皖北煤电集团总医院2008年10月-2010年5月住院分娩的初产妇,孕周为37～41周,入室胎心监护(包括无应激试验或宫缩应激试验)基线变异为静止型的产妇63例为观察组,排除药物影响及胎儿睡眠状态,胎心监护变异为波浪形的产妇112例为对照组,回顾性分析比较两组分娩过程情况及新生儿结局。结果基线变异静止型产妇分娩过程中出现羊水Ⅱ度～Ⅲ度污染、羊水过少、新生儿中、重度窒息及围生儿死亡的病例数显然高于波浪组,采用χ2检验差异有统计学意义(P<0.05或P<0.01)。结论胎心监护基线变异静止型,常提示胎盘的储备能力下降,多合并羊水过少、羊水Ⅱ度～Ⅲ度污染、妊娠合并症或并发症,存在胎儿潜在宫内缺氧的可能,临床应给予高度重视,尽早产科干预对降低新生儿窒息及病死率有重要意义。
Objective To investigate the relationship between baseline variability of fetal heart rate variability and fetal hypoxia. Methods random selection Wanbei Coal and Metallurgical Group General Hospital October 2008 - May 2010 hospital delivery of primipara, gestational age 37 to 41 weeks, admission fetal heart rate monitoring (including no stress test or contractions stress test ) The baseline variability of quiescent maternal 63 cases for the observation group, excluding drugs and fetal sleep status, fetal heart rate variability of wave-shaped maternal 112 cases as control group, retrospective analysis of the two groups of childbirth and neonatal outcomes . Results The baseline variability of quiescent mothers during the delivery of amniotic fluid Ⅱ degree Ⅲ degree of pollution, oligohydramnios, neonatal moderate to severe asphyxia and perinatal deaths were significantly higher than the wave number of cases, the use of χ2 test difference was statistically significant (P <0.05 or P <0.01). Conclusion Fetal heart monitoring baseline variability of static type, often suggesting that the reserve capacity of the placenta decreased polyhydramnios, amniotic fluid Ⅱ degree Ⅲ degree of pollution, complications or complications of pregnancy, the fetus potential intrauterine hypoxia possible clinical should Give priority to, as soon as possible obstetric interventions to reduce neonatal asphyxia and mortality is of great significance.
