What is Intrauterine Growth Restriction?
-
Intrauterine growth restriction is defined as a fetus in the 10th percentile or less for its gestational age. It is also identified by the mother's abdominal circumference being in less than the 2.5 percentile.
Diagnosis
-
One of the most common ways of diagnosing irregularities in fetal growth is through ultrasound. Measuring the body and head of the fetus and comparing these dimensions with a growth chart for average fetal measurements allows the doctor to determine if there is irregular fetal growth.
-
Causes
-
Chromosomal abnormalities like Turner syndrome and trisomy can restrict fetal growth. Substance abuse, poor maternal diet, chronic conditions of the mother and problems with the placenta are other possible causes.
Treatment
-
Every case must be treated individually and the cause of irregular growth may play a large part in how it is treated. Bed rest, nutritional enhancement of the mother's diet and early delivery can help ensure the fetus receives the best opportunity for continued growth.
Delivery
-
If growth restrictions jeopardize the fetus's health, early delivery at a hospital that is qualified to handle post partum complications may be recommended. Intrauterine growth restrictions caused by placenta previa may require Cesarean section delivery for the benefit of both mother and baby.
