Fetal distress refers to signs before and during childbirth indicating that the fetus is not well.
Fetal distress is an uncommon complication of labor. It typically occurs when the fetus has not been receiving enough oxygen. Fetal distress may occur when the pregnancy lasts too long (postmaturity) or when complications of pregnancy or labor occur.
Usually, doctors identify fetal distress based on an abnormal heart rate pattern in the fetus. Throughout labor, the fetus’s heart rate is monitored. It is usually monitored continuously with electronic fetal heart monitoring. Or, a handheld Doppler ultrasound device may be used to check the heart rate every 15 minutes during early labor and after each contraction during late labor.
If a significant abnormality in the heart rate is detected, it can usually be corrected by the following:
Sometimes the amniotic fluid (fluid around the fetus in the uterus) appears green after the membranes have ruptured. This discoloration is caused by the fetus’s first stool (called meconium). Sometimes the baby inhales (aspirates) amniotic fluid containing the meconium before labor or during delivery. If the baby inhales meconium, the baby may have difficulty breathing shortly after birth (called meconium aspiration syndrome).
