目的研究胎儿血氧饱和度(FSaO2)监测方法在产程中的应用,探讨其对诊断胎儿窘迫、新生儿窒息方面的临床意义。方法监测产程不同时段FSaO2值,监护并记录胎心率-宫缩曲线图(CTG),观察羊水粪染情况,分娩后脐血血气分析,并观察新生儿Apgar评分。结果①FSaO2值在CTG正常及CTG异常时其差异有极显著性意义;②羊水清亮者FSaO2值与羊水粪染Ⅱ～Ⅲ度者FSaO2值比较,差异有显著性意义;③FSaO2值<30%作为诊断标准预测胎儿酸中毒、新生儿窒息,其准确性高于CTG、羊水粪染观测方法。结论FSaO2能较为准确地反应胎儿氧合状态及酸碱平衡状态,FSaO2及CTG联合使用,结合羊水性状观察能更为准确地预测胎儿、新生儿情况。
Objective To study the application of FSaO2 monitoring in labor process and its clinical significance in the diagnosis of fetal distress and neonatal asphyxia. Methods The levels of FSaO2 in different stages of labor were monitored, the fetal heart rate (CTG) was monitored and monitored, the meconium-stained amniotic fluid was observed, blood gas analysis of cord blood after delivery and Apgar score of neonates were observed. Results (1) There was significant difference in the value of FSaO2 between normal CTG and abnormal CTG. (2) There was significant difference between FSaO2 value of amniotic fluid creatinine and FSaO2 value in amniotic fluid meconium Ⅱ ~ Ⅲ degree. ③The value of FSaO2 <30% Standard prediction of fetal acidosis, neonatal asphyxia, its accuracy is higher than the CTG, amniotic fluid meconium observation method. Conclusion FSaO2 can more accurately reflect the status of fetal oxygenation and acid-base balance, FSaO2 and CTG combined use of amniotic fluid traits combined with the observation can be more accurately predict fetal and neonatal conditions.
