OBJECTIVE
Evaluation of the relationship between umbilical coiling index (UCI) and adverse perinatal outcome.
METHOD
A prospective study was performed on 699 pregnant women who were 37-40 weeks. UCI was determined by dividing the total number of the complete vascular coiling by the total umbilical cord length in centimeters. Then the relationship between UCI and neonatal weight, amniotic fluid index, meconium, Apgar score, and fetal distress were evaluated.
RESULTS
There was a significant difference between normo- and hypocoiled groups according to the Apgar score less than 7 in minute 5, AFI<or=5; and between normo- and hypercoiled groups according to Apgar score less than 7 in minute 5, AFI<or=5, meconium, and fetal distress. Neonatal weight in normocoiled was higher than hypercoiled group. AFI<or=5, meconium and fetal distress were higher in hypercoiled than hypocoiled group. Neonatal weight in hypercoiled was less than that in the hypocoiled group, respectively.
CONCLUSION
Abnormal UCI may relate to adverse perinatal outcome.
目的
评估脐带螺旋指数（UCI）与围产期不良结局之间的关系。
方法
对699例孕周为37 - 40周的孕妇进行前瞻性研究。UCI通过将完整血管螺旋的总数除以脐带总长度（以厘米为单位）来确定。然后评估UCI与新生儿体重、羊水指数、胎粪、阿氏评分和胎儿窘迫之间的关系。
结果
根据出生后5分钟阿氏评分小于7分、羊水指数≤5；以及根据出生后5分钟阿氏评分小于7分、羊水指数≤5、胎粪和胎儿窘迫情况，正常螺旋组与螺旋减少组之间存在显著差异。正常螺旋组的新生儿体重高于螺旋增加组。螺旋增加组中羊水指数≤5、胎粪和胎儿窘迫的发生率高于螺旋减少组。螺旋增加组的新生儿体重分别低于螺旋减少组。
结论
异常的UCI可能与围产期不良结局有关。
