诊断妊娠期宫内生长迟缓(IUGR)常感困难。目前已证明非应激试验(NST)估计胎儿急性窘迫最准确,当IUGR胎儿处于危险应娩出时,NST也是最后的决定因素。如胎儿监护正常,胎肺成熟,IUGR胎儿可安全分娩。严重IUGR胎儿胎肺不成熟,欲立即分娩,常难处理。此时必须比较胎儿早产与继续在子宫内不利环境中的危险后决定。本文报道4例IUGR病例,孕期在28～33周之间,体重425～1500g,胎心监测证实胎儿险危,2～24小时后均胎死宫内。例1:双胎妊娠,孕33周早产,腹部和B超检查双胎的双顶径均小于相应孕龄。胎心监护双胎A显示正常图形,而双胎B短期可变性减少,一阵间
Diagnosis of intrauterine growth retardation during pregnancy (IUGR) often feel difficult. Non-stress tests (NST) have now been shown to be the most accurate estimate of fetal acute distress, with NST being the final determinant when IUGR fetuses are at risk for delivery. Such as normal fetal care, fetal lung maturity, IUGR fetus can be safely delivered. Severe IUGR fetal lung immature, want immediate delivery, often difficult to deal with. At this point must be compared fetuses premature birth and continue in the uterus unfavorable environment after the decision. This article reports 4 cases of IUGR cases, between 28 and 33 weeks of pregnancy, body weight 425 ~ 1500g, fetal heart rate monitoring confirmed fetal danger, 2 to 24 hours after intrauterine fetal death. Example 1: Twin pregnancies, 33 weeks pregnant preterm birth, abdominal and B-ultrasound biparietal diameter were less than the corresponding gestational age. Twin fetus A showed normal pattern while Twin B short-term variability was reduced for a while
