A nuchal cord is when the umbilical string becomes wrapped effectually the fetus's neck.[1] Symptoms present in the baby shortly after birth from a prior nuchal cord may include duskiness of face up, facial petechia, and bleeding in the whites of the center.[i] Complications can include meconium, respiratory distress, anemia, and stillbirth.[ane] Multiple wraps are associated with greater risk.[3]

The diagnosis may be suspected if in that location is a subtract in the baby'due south heart rate during delivery.[1] Nuchal cords are typically checked for by running the finger over the baby'southward neck once the head has delivered.[iv] Ultrasound may pick up the condition before labor.[1]

If detected during delivery, direction includes trying to unwrap the string or if this is not possible clamping and cutting the cord.[2] Commitment can typically take identify every bit normal and outcomes are generally skilful.[5] [1] Rarely long term encephalon damage or cognitive palsy may occur.[1] [half-dozen] Nuchal cords occur in about a quarter of deliveries.[2] The condition has been described at least as early on as 300 BC by Hippocrates.[1]

Signs and symptoms [edit]

Symptoms of a prior nuchal cord shortly afterwards nativity in the baby may include duskiness of face up, facial petechia, and haemorrhage in the whites of the eye.[1] Complications can include meconium, respiratory disease, anemia, and still birth.[1]

  • Petechiae on confront due to tight nuchal cord

  • Facial duskiness due to tight nuchal cord

  • Abrasion from a nuchal cord

Diagnosis [edit]

In 1962, J. Selwyn Crawford MD from the British Research Quango defined a nuchal cord as one that is wrapped 360 degrees around the fetal neck. Crawford commented "It is all the more remarkable, therefore, that footling piece of work has been done. to analyze its effects during labor and delivery".[ commendation needed ] To date, at that place is no prospective example control double-blind study looking at nuchal cords and observational studies vary in opinion equally to the caste of poor outcomes. Also non included in these studies is which umbilical cord form (of the eight dissimilar possible structures) was considered a nuchal string.[ citation needed ]

Ultrasound diagnosis of a cord around the neck was starting time described in 1982.[7] "Coils occur in about 25% of cases and ordinarily practice no harm, but occasionally they may be so tight that constriction of the umbilical vessels and consequent hypoxia consequence."[ citation needed ] Williams Obstetrics 16th Edition, has but ane unmarried sentence in the entire textbook regarding cords effectually the neck.[8] By contrast, the First Edition of the Encyclopædia Britannica from 1770 had 20 pages of information almost Umbilical Cord Pathology with drawings of Umbilical Cord Entanglement. The Royal Higher of Obstetricians and Gynaecologists has these images on its brochure. At that place are currently three recent texts on ultrasonography which demonstrate the power of ultrasound to place umbilical cord issues with reliability as of 2009.[ citation needed ]

A study published in 2004 was done to establish the sensitivity of ultrasound in the diagnosis of a nuchal string. Each of 289 women, induced the same mean solar day, underwent a transabdominal ultrasound scan with an Aloka 1700 ultrasound machine with a 3.five MHz intestinal probe, using gray-calibration and colour Doppler imaging immediately prior to induction of labor. Presence of the cord was sought in the transverse and sagittal airplane of the neck. A nuchal cord was diagnosed if the cord was visualized lying around at to the lowest degree 3 of the 4 sides of the neck. A cord was actually present at delivery in 52 of the 289 women. Only 18 of the 52 cords or 35% of the nuchal cords were detected on ultrasound washed immediately earlier delivery, and 65% of nuchal cords were not detected. Of the 237 cases where in that location was no cord at delivery, ultrasound had false positive results, i.east. diagnosed a cord in 44 of the 237 cases (19%) in which in that location was no cord present at all. In this report, ultrasound was only 35% authentic at finding a unmarried loop, and only 60% authentic at detecting a nuchal cord wrapped multiple times around the neck.[ix]

In no report was it possible past ultrasound to distinguish between a loose or a tight cord, although at least 3 attempted to do so.[ commendation needed ] Peregrine[9] concludes that ultrasound diagnosis of nuchal cords will merely be useful if doctors are able to do so reliably and predict which of those fetuses are likely to take a trouble., However, perinatologists routinely look for umbilical cord issues in monoamniotic twins. Studies have shown an improvement in outcomes where string entanglement was prenatally identified in these cases. Ultrasound measurement of the velocity of menses in the cord may be useful in the management of twins and chronically growth-retarded fetuses. Of grade this depends on the grooming of the sonographer. To date in that location are no ultrasound courses which teach the identification of nuchal cord to physicians or technicians. A recent review by Wilson of the American Academy of Ultrasonography Technicians recommends the documentation of umbilical cord issues.[ten]

Classification [edit]

  • A "Type A" nuchal cord is wrapped around the neck simply is gratuitous sliding[ane]
  • A "Type B" pattern is described as a hitch which cannot exist undone and ends upward as a true knot.[xi]

  • Nuchal cord - free sliding[1]

  • Nuchal cord - locked pattern[1]

Treatment [edit]

Management of a presenting nuchal cord should exist tailored to prevent umbilical cord compression whenever possible. Techniques to preserve an intact nuchal cord depend on how tightly the cord is wrapped effectually the infant's neck. If the string is loose, it can easily be slipped over the babe's head. The babe can be delivered normally and placed on maternal belly every bit desired. If the string is too tight to go over the infant's head, the provider may be able to slip information technology over the baby's shoulders and evangelize the trunk through the string. The cord can then be unwrapped from around the infant afterward birth. Finally, if the string is too tight to slip back over the shoulders, 1 may utilize the somersault maneuver to permit the body to be delivered.[12] The nativity attendant may also cull to clench and cutting the umbilical string to allow for vaginal commitment if other methods of nuchal cord management are non feasible.

Prognosis [edit]

Retrospective data of over 182,000 births, with the statistical ability to determine even mild associations, suggest that a single or multiple nuchal cords at the time of delivery is not associated with adverse perinatal outcomes, is associated with college birthweights and fewer caesarean sections in births.[13] [14] [15] Although some studies accept found that a tight nuchal cord is associated with curt term morbidity, it is unclear whether such outcomes are really a issue of the presence of the nuchal string itself, or every bit a upshot of clamping and cutting the cord [16]
