To investigate the clinical significance of umbilical cord length in human pregnancies, 1087 deliveries at Kaohsiung Chang Gung Memorial Hospital from May 1995 to August 1995 were studied. Our data showed that male fetuses had longer cord length than female and vertex presentation had longer cord length than breech presentation. The cord length and placental weight were significantly related to the birth weight. We found that: 1) only intrauterine growth retardation was associated with the increased risk of fetal distress; 2) secondary arrest of labor and advanced gestational age were correlated with meconium stain; and 3) birth weight and presence of meconium stain were correlated with the secondary arrest (p < 0.05). However, there was no significant correlation between umbilical cord length and fetal well-being. As a result of multivariate analyses, we conclude that the umbilical cord length does not significantly correlate with either maternal age, gestational age (> or = 28 weeks), parity fetal outcome or intrauterine fetal well-being. Birth weight is the only characteristic that is correlated with cord length.
为探讨人类妊娠中脐带长度的临床意义，我们研究了1995年5月至1995年8月高雄长庚纪念医院的1087例分娩病例。我们的数据显示，男胎的脐带长度长于女胎，头先露的脐带长度长于臀先露。脐带长度和胎盘重量与出生体重显著相关。我们发现：1）只有宫内生长受限与胎儿窘迫风险增加有关；2）继发性产程停滞和孕周增加与胎粪污染相关；3）出生体重和胎粪污染与继发性产程停滞相关（p<0.05）。然而，脐带长度与胎儿健康状况之间无显著相关性。多因素分析结果显示，我们得出结论，脐带长度与母亲年龄、孕周（≥28周）、产次、胎儿结局或宫内胎儿健康状况均无显著相关性。出生体重是与脐带长度相关的唯一特征。
