This study was designed to investigate the relationship between fetal heart rate patterns before delivery and periventricular-intraventricular hemorrhage in the very low birth weight infant.
The last 30 minutes of electronic fetal heart rate data preceding delivery were analyzed for 84 singleton infants weighing between 700 and 1500 gm. All these infants received serial cranial ultrasonographic examinations commencing within 24 to 48 hours of birth.
Thirty-three fetuses had normal heart rate patterns, and 51 had fetal heart rate abnormalities. Periventricular-intraventricular hemorrhage was not associated with fetal heart rate abnormalities. Univariate and multivariate regression analysis demonstrated that only gestational age < 28 weeks was a significant contributing factor to periventricular-intraventricular hemorrhage (odds ratio 2.2, 95% confidence interval [CI], 1.0 to 4.8).
Fetal heart rate patterns immediately preceding delivery are not predictive of periventricular-intraventricular hemorrhage in the very low birth weight infant.
本研究旨在探讨极低出生体重儿分娩前胎儿心率模式与脑室周围-脑室内出血之间的关系。
对84例体重在700至1500克之间的单胎婴儿分娩前最后30分钟的电子胎儿心率数据进行分析。所有这些婴儿在出生后24至48小时内开始接受系列头颅超声检查。
33例胎儿心率模式正常，51例有胎儿心率异常。脑室周围-脑室内出血与胎儿心率异常无关。单因素和多因素回归分析表明，只有胎龄<28周是脑室周围-脑室内出血的一个重要促成因素（比值比2.2，95%置信区间[CI]，1.0至4.8）。
极低出生体重儿分娩前即刻的胎儿心率模式不能预测其脑室周围-脑室内出血情况。
