The Statistics of Labor Inductions
There has been a dramatic rise in the labor induction rate in the last 15 years. According to the National Center for Health Statistics, the rate of inductions was 9.5% in 1990. In 2003, the rate more than doubled to reach 20.6%. There is reason to believe that the most current labor induction rates might, in fact, be under-reported. According to a 1999 review of 7,000 consecutive inductions, published in the American Journal of Obstetrics and Gynecology, (the Green Journal) the number of labor inductions may be closer to 40% in some community hospitals. Similar findings were reported in the 2002 Listening to Mothers survey. Of the nearly 1600 mothers interviewed, 49% who gave birth vaginally reported that their medical provider attempted to induce their labor and 44% actually had their labor induced
Provider's Choice
Some providers may recommend an induction to their patients for a number of reasons. One reason might be the suspected size of the baby. The difficulty in late pregnancy is accurately predicting the baby's size since ultrasound measurements are based on percentiles. These percentiles measure the "average weights" of babies, however the estimates are not always accurate.
For example, one of my doula clients had an ultrasound that estimated her baby's weight to be 9 pounds. One of the measurements used is the length of the femur, which is the bone in the thigh and also the longest bone in the body. It turned out that her baby's weight at birth was only 6 1/2 pounds since he had very long, skinny legs!
Another reason for a provider to advise an induction is when the mother's due date has passed. Babies who are truly post-term can have more complications. However, this diagnosis must be made based on more than simply dates. Specific testing can be done, such as a biophysical profile, which measures the amount of amniotic fluid in the uterus, the breathing movements and the baby's heart rate. This would give the provider and parents a more accurate indication of a post-term baby (and ultimately a labor that needs to be induced!) rather than looking at the due date alone.
It is important that parents take the time to discuss all of their options with their provider before any procedure is recommended.
