Understanding how a baby gets its oxygen allows us to understand why a baby cannot strangle or â€śchokeâ€ť on its cord. In order to choke, one must be using its tracheato breath air. Clearly, there is no air in the uterus, the baby does not breathe through its throat and, therefore, cannot choke. When an ultrasound reveals the cord around the neck it is a normal human response to anthropormorphasize the intrauterine baby to our extrauterine experience. But this is not the case and there is no reason to have fear. So, letâ€™s dispel once and for all the rumor that a cord around the neck (nuchal cord) is more dangerous than any other situation. About 35-40% of normal term babies are born with the cord around the neck at least once. It can also be wrapped around the body or legs or even at times have a true knot. None of which are usually significant as the cord is designed to deal with this.
Cord compression can occur anytime during pregnancy. The cord is well equipped to handle temporary squeezing as the 3vessels are cushioned by a matrix called Whartonâ€™s jelly and the surrounding amniotic fluid. In labor, sometimes after the bag of waters breaks and fluid leaks out,the cord can be repeatedly compressed with contractions. This is not uncommon and is not, by itself, a sign of distress. Your practitioner or nurse can listen to or interpret the fetal heart rate pattern to know whether any intervention is necessary. And the compression of the cord almost never is an emergency or acause for the tragic death of a baby inside the womb. When that tragedy occurs we all want to know why and often, mistakenly, we are told it was a â€ścord accidentâ€ť. Compared to the number of times I have heard this mentioned by patients or news stories the real truth is that this is a very rare event.
Please be reassured that your baby will not strangle on its cord because it is not breathing through its neck like you and I. If you hear someone repeat this rumor youwould be doing agreat service to pregnant women everywhere by logically explaining to them the reasons why.
