Management of the Nuchal Cord at Birth
Background and aim: Although nuchal cord is a common occurrence at birth, there is little attention to its importance or management at birth, and teaching includes premature clamping and cutting of the cord as the common option. Although grade 1 evidence is lacking, the optimal management of the nuchal cord, the Somersault manoeuvre is not taught or included in any current guidelines. What e...
متن کاملThe effect of nuchal cord on nuchal fold thickness measured in the second trimester.
PURPOSE To find out whether nuchal cord causes an effect on the nuchal skin fold thickness (NFT) measurements, or not. PATIENTS AND METHODS A total of 242 fetuses with normal outcomes that had undergone detailed second trimester US scan between 18 and 24 weeks of gestation were included in the study. NFT measurements were made on axial cranial US images passing through the cerebellum and cavu...
متن کاملCystic hygromas, nuchal edema, and nuchal translucency at 11-14 weeks of gestation.
OBJECTIVE To estimate the incidence of septations in fetuses with increased nuchal translucency (NT) thickness, and to investigate the relationship between the length and thickness of the translucency and whether the length or septations provide useful information concerning the fetal karyotype in addition to that provided by the NT thickness alone. METHODS We examined 386 fetuses with NT thi...
متن کاملNuchal translucency and gestational age.
Professor Wald and his team (Wald et al., 2004) have remodelled the already modelled SURUSS data (Wald et al., 2003a) to claim, firstly, that their results are now similar to those of the multicentre study co-ordinated by the Fetal Medicine Foundation (Snijders et al., 1998), and, secondly, that the gestation of choice for nuchal translucency (NT) measurement is 10 weeks. The latest modelling e...
متن کاملNuchal translucency in multiple pregnancies.
AIM To evaluate the prevalence of increased nuchal translucency (NT) in multiple pregnancies and its relation to fetal karyotype and pregnancy outcome. METHODS We measured fetal nuchal translucency (NT) in 6,338 women pregnant from 10+3 to 13+6 weeks by ultrasound and evaluated the prevalence of NT=95th centile in 115 multiple pregnancies, including 100 pairs of twins (70 dichorionic and 30 m...
