Objectives:To assess effect of nuchal cordn on perinatal infant.Methods:Retreopective analysis of 294 clinical records was emploide fo assess:(1)The correlation of cord length and nuchal cord neck.(2)Perinatal conseguence with as without nuchal cord.(3)Contrest the number of cord entanglement neck with the effect on perinatal infants.Results:There wasn’t cord entanglememt in short cord group.There were more cycles of cord entanglement in long cord group than those in normal length cord group(P<0.01).In nuchal cord group,the rate of fetal distress was 24.5%,newborn asphyxia 10.2%,fetal death 2.04%,Conclusions:There was a correlation of nuchal cord with cord length.Long cord was mains factors which result in cord entanglement.The more cyeles of cord entanglement were associated with higher rates of fetal distress,fetal death and newborn asphyxia.
