胎儿脉搏氧在产时不可靠胎心监护图形应用的临床价值
Clinical value of fetal pulse oximetry in irresponsible fetel heart rate patterns in intrapartum cardiotocography
【摘要】 目的:研究胎儿脉搏氧在产时不可靠胎心监护图形应用的临床价值。方法:选择161例无妊娠合并症和并发症的足月、单胎、头位的初产妇,随机分为研究组81例,在胎心电子监护(CTG)的同时使用胎儿脉搏氧监护胎儿的氧合状况,对照组80例行胎心电子监护。比较两组的剖宫产率、新生儿窒息率及脐动脉pH值与出生前胎儿脉搏氧测定值的相关性。结果:研究组剖宫产率为29.63%,明显低于对照组的41.25%,两者比较差异有显著性(P<0.05);两组新生儿窒息率无显著差异,分别为4.94%和6.25%(P>0.05);研究组脐动脉pH值与出生前胎儿脉搏氧具有明显的相关性(相关系数r=0.8123,P<0.05)。结论:在产时胎心电子监护出现不可靠图形时,联合应用胎儿脉搏氧监测,可有效降低剖宫产率,不增加新生儿窒息率。
【Abstract】 Objective:To determine the clinical value of fetal pulse oximetry in irresponsible fetal heart rate patterns in intrapartum cardiotocography(CTG).Methods:161 term primiparas were divided randomly into two groups. The fetal oxygen saturation of observed group (n=81)was measured through fetal pulse oximetry in uterus in continuously CTG.Ones in control group (n=80) was under electronic fetal monitoring. Rates of cesarean section and neonatal asphyxia were compared between two groups. Correlation between umbilical arterial pH and fetal oxygen saturation was estimated.Results:Rate of cesarean section in observed group was lower than that in control group (29.63% vs 41.25%,P<0.05). There was no significant difference in the rate of neonatal asphyxia between two groups, respectively 4.94% and 6.25% (P>0.05). Correlation between umbilical arterial pH and fetal oxygen saturation was obviously observed (r= 0.812 3,P<0.05). Conclusion:When fetal pulse oximetry was applied in labor with irresponsible fetal heart rate tracing in cardiotocography, rate of cesarean section would be decreased and rate of neonatal asphyxia could not increase.
