Résumé
Objective To investigate the healthy status of newborns with isolated single umbilical artery(ISUA).Methods A retrospective analysis was performed between newborns with ISUA (ISUA group,n =78)or without ISUA (control group,n =78),which were borned in our hospital during Jun 2006 ～Oct 2012.We compared the Apgar score at 1 and 5 minute,birth-weight,incidence of newborns admitted by neonate intensive care unit and pH value of umbilical arterial blood.The incidence of mothers amniocentesis for prenatal chromosome examination and outcomes of two groups were investigated.Results The birthweight of newborns with ISUA[(3246 ±75) g] was lower than that of the control group[(3565 ±58) g],the difference was statistically significant(P ＜ 0.05).While the differences of Apgar score,the incidence of newborns admitted by neonate intensive care unit,and pH value of umbilical arterial blood between two groups showed no significance (P ＞ 0.05).There were 26 cases underwent amniocentesis in ISUA group,however 1 case in control group.The fetal chromosomal tests were normal.Conclusion The healthy status of newborns with ISUA are the same as the newborns with three-vessel umbilical cord,and we need not take more care of the newborns with ISUA.
