Pregnancy

In Utero Diaphragm Problems

09/21/2009

Question:

The baby is due end of September and today was told the diaphragm is not moving much. What does that mean for the health of the baby? Does the affect the oxygen going to the brain? Is there any treatment? Will a c-section be necessary? What stresses will this problem place on the baby?

Answer:

I assume you are referring to fetal breathing movements and not a structural problem with the diaphragm.  Fetal breathing movements are used in a biophysical profile (an ultrasound assessment of fetal well-being) as one of  five assessments.  Breathing is sometimes not seen on this test and, if the other four elements are fine, the test will be repeated in 3 to 5 days.  If breathing is consistently not seen, that may be a sign of poor oxygen to the fetus and a reason to deliver the baby.

Fetuses do not have to breathe in the womb in order to get oxygen.  The fetal lungs are not used until the birth of the infant.
