A nuchal cord is when the umbilical cord becomes wrapped around the fetus's neck.[1] Symptoms present in the baby shortly after birth from a prior nuchal cord may include duskiness of face, facial petechia, and bleeding in the whites of the eye.[1] Complications can include meconium, respiratory distress, anemia, and stillbirth.[1] Multiple wraps are associated with greater risk.[3]
The diagnosis may be suspected if there is a decrease in the baby's heart rate during delivery.[1] Nuchal cords are typically checked for by running the finger over the baby's neck once the head has delivered.[4] Ultrasound may pick up the condition before labor.[1]
If detected during delivery, management includes trying to unwrap the cord or if this is not possible clamping and cutting the cord.[2] Delivery can typically take place as normal and outcomes are generally good.[5][1] Rarely long term brain damage or cerebral palsy may occur.[1][6] Nuchal cords occur in about a quarter of deliveries.[2] The condition has been described at least as early as 300 BC by Hippocrates.[1]
