To establish whether the presence of umbilical cord encirclements around the fetal body influence fetal growth.
The encirclements, cord length, gestational age, and fetal weight at birth were recorded for 11,201 births occurring at our hospital during 1991-1994.
The presence of umbilical cord encirclements is associated with fetal growth restriction (FGR), the severity of the restriction being positively related to the number of encirclements. Umbilical cord encirclements are also associated with a relative lengthening of the umbilical cord. Because there is a positive correlation between cord length and fetal weight, this association tends to offset the effects of the encirclements, giving the newborns a more normal birth weight than they would have had otherwise. The net result, however, is negative.
Umbilical cord encirclements are associated with FGR.
确定胎儿身体周围脐带绕颈的情况是否会影响胎儿生长。
记录了1991年至1994年在我院出生的11201例新生儿的脐带绕颈情况、脐带长度、孕周和出生时的胎儿体重。
脐带绕颈与胎儿生长受限(FGR)有关,受限的严重程度与绕颈的次数呈正相关。脐带绕颈还与脐带相对延长有关。由于脐带长度与胎儿体重呈正相关,这种关联往往会抵消绕颈的影响,使新生儿出生体重比没有绕颈时更接近正常。然而,最终结果是负面的。
