Perinatal events of 180 babies with nuchal cord (umbilical cord entanglement around foetal neck) over one year have been studied. The incidence of nuchal cord was 5.74% of all hospital deliveries. More than one third (39%) of them had tight nuchal cord (TNC) and 61% had loose nuchal cord (LNC). Babies with TNC were more frequently met with foetal distress (51%), prolonged second stage (11%), non-toxaemic accidental haemorrhage (7%) and operative delivery (56%) when compared to babies with LNC and controls (without nuchal cord). Nearly one fourth (24%) of the babies with TNC were born as small for date, had birth asphyxia (61%) and 8.5% died during perinatal period. Perinatal outcome was adversely affected by TNC in comparison to LNC and controls.
对180例有脐带绕颈（脐带缠绕胎儿颈部）的婴儿在一年中的围产期情况进行了研究。脐带绕颈的发生率占所有医院分娩的5.74%。其中超过三分之一（39%）为紧脐带绕颈（TNC），61%为松脐带绕颈（LNC）。与LNC婴儿和对照组（无脐带绕颈）相比，TNC婴儿更常出现胎儿窘迫（51%）、第二产程延长（11%）、非子痫性意外出血（7%）和手术分娩（56%）。近四分之一（24%）的TNC婴儿为小于胎龄儿，有出生窒息（61%），8.5%在围产期死亡。与LNC和对照组相比，TNC对围产期结局有不利影响。
