Q: Can anyone tell me the specifics of knots in cords at birth? I've
received several inquiries from students as to how common this is; what, if
any, are the complications that might occur; if a knot in the cord could
often produce a stillbirth; and finally, are there any preventions?
-Jenna Tamura
A: I am a UK trained midwife with 14 years experience. I have seen many
variations of knots. We were taught that there were two types: "false"
knots occur when the vessels in the cord clump and bulge together inside
the cord itself. They sort of make 's' shapes and create areas on the cord
that look "knotty" but don't interfere with the circulation of blood. The
second is "true" knots where the baby has somehow swum through a loop of
cord and actually created a knot. At least I surmise this is how they are
created.
It depends on where the knot occurs, how long the cord is and how tight the
knot becomes either during the baby's wiggling inside or during the journey
into the outside world, as to whether it becomes a serious issue. If the
knot pulls tight so as to cut off circulation, the baby will experience
hypoxia and possibly anoxia. I have seen babies who have died because of a
true knot in the cord. They are extremely rare, though. Please reassure
your students that it is a rare happening. I have not heard of anything
that can be done to prevent this knotty problem, but I'm continually
surprised in life, so who knows?
