| | To promote clinical practice of C/P value for diagnosis and prediction, the correlation of ratio between PIMcA and PiUA and umbilical artery blood hypoxia of the neonate were investigated. Fifty two cases in the third trimester of pregnancy were examined with pulsed Doppler ultrasound technigue for their, fetal blood flow velocrity waveforms of middle cerebral artery and umbilical artery. C/P ratio was compared to blood gas,values of umbilical artery obtained at selective cesarean section and perinatal$$... | | 研究胎儿大脑中动脉搏动指数(PI_MCA)和脐动脉搏动指数(PI_UA)之比(C/P)与新生儿脐动脉低氧血症的关系,使C/P值应用于临床诊断和预测。应用多普勒超声技术,对52例妊娠晚期妇女进行胎儿MCA和UA血流速度波型检查,将C/P值与选择性剖宫产相应新生儿脐动脉血气分析和围产儿结局比较。结果:正常妊娠胎儿C/P值为2.0,重度妊高征、过期妊娠及重度胎动异常孕妇胎儿C/P值小于1;C/P值的降低与新生儿脐动脉低氧、酸中毒及不良围产儿结局相关。结论:C/P值是估计妊娠晚朗胎儿宫内低氧、预测宫内窘迫的敏感指标。 | | 文摘来源 | | Objective: To study the effect of gestational impaired glucose tolerance (GIGT) on fetus and newborns. Methods: 52 GIGT mothers and 34 gestational diabetes mothers (GDM) were subjected to systematic monitoring prospectively, other 44 normal mothers served as controls. The perinatal outcomes were compared in the three groups. Results: The incidence of macrosmia in the GIGT group was higher than that of the control group ( P <0.025). Neonatal blood glucose level in the GIGT group at 2 hours of a... | | 目的:探讨妊娠期糖耐量降低(GIGT)对胎儿及新生儿的影响。方法:对GIGT孕妇52例(GIGT组),妊娠期糖尿病(GDM)孕妇34例(GDM组),正常孕妇44例(对照组)的围产儿结局进行比较。结果:GIGT组巨大儿发生率高于对照组(P<0.025),生后2小时的血糖均值在3组中最低(P<0.05),低血糖、红细胞增多症等并发症高于对照组。结论:GIGT与GDM均是影响胎儿及新生儿预后的重要因素。 | | 文摘来源 | | Objective:In order to find a convenient and feasible method of predicting and monitoring perinatal outcome, we studied the correlation between the flow parameters of fetal MCA,RA,amniotic fluid index and perinatal outcome.Methods:According to AFI, 96 patients of third trimester gestation with or without oligohydramnios were divided into three groups. That was,groupl 1(AFI<5.0 cm);group 2(AFI 5.1~8.0 cm);group 3(AFI 8.1~18.0 cm). HFUPR,M/R PI and the flow parameters(S/D,PI,RI) of feta... | | 目的:研究胎儿肾、脑动脉血流参数和羊水指数与围产儿预后的关系,探讨预测胎儿不良结局的方法。方法:应用彩超Doppler,根据羊水指数(AFI)值,将临产妇分为羊水量过少组、减少组和正常组。测定各组胎儿脑动脉(MCA),肾动脉(RA)血流参数(S/D、PI、RI)及胎儿小时尿量(HFUPR),M/RPI。结果:羊水量减少组的胎儿RA的血流参数明显高于正常组(P<0.01)。AFI与MCAPI,HFUPR,M/RPI间呈正相关关系(r=0.206,0.569,0.379;P<0.05~0.01),而与RAPI及围产儿预后呈负相关关系(r=-0.397,-0.702;P<0.01)。结论:AFI测定是预测胎儿不良预后的简易方法 | | 文摘来源 | |   | | << 更多相关文摘 |
