Increased Chances of Birth Complications with Elective Induction


Increased Chances of Birth Complications with Elective InductionIn a study, published in Acta Obstetricia et Gynecologica Scandinavica, Dr. Rosalie Grivell from the University of Adelaide�s Robinson Institute and School of Paediatrics and Reproductive Health studied the data of more than 28,000 births from across South Australia, from 2006 to 2007. She compared cases in which women had undergone spontaneous onset of labor, induction of labor for recognized medical reasons, and induction of labor for �non-recognized� reasons.

Compared with women who entered labor spontaneously, induction for non-recognized reasons was associated with  

  • A 67 percent increased chance of requiring a caesarean section: Sometimes induction might not be successful. As the bag of water has been broken, either naturally or via an amniotomy. The risk of infection is greater, and the baby will need to be born via c-section. A cesarean in an induced labor is also more likely reason for fetal distress.

  • Significantly increased chances of  newborn infant requiring nursery care in a Special Care Baby Unit (an increased risk of 64 percent):  Babies who are born via induction aren't yet ready to be born. The risk is worth it if the baby or mother's lives are in danger, but simply to take this risk for elective reasons may not be well advised. When a baby is in the intensive care unit there is less ability for you to be with your baby or to hold your baby. Breastfeeding usually gets off to a rocky start as well. This can usually be avoided by giving birth when your body and baby say it is time. Or,


  • Requiring treatment (an increased risk of 44 percent) compared with infants born following spontaneous onset of labor.  Your baby may also be more likely to suffer from jaundice at or near birth because of the induction. This can lead to other medical treatments as well as stays in the hospital for your baby.

Other Risks included are:

  • Placental Abruption:  The nature of induction like contractions may also be more forceful than natural labor. This can cause your baby to assume or stay in an unfavorable position for labor making labor longer and more painful for the mother.

  • Fetal Distress:  Labor induction is done by intervening in the body's natural process, typically with powerful drugs to bring on contractions or devices that are used to break the water before labor starts. Both of these types of induction can cause the baby to react in a manner that is called fetal distress as seen by fetal monitoring.

  • Uterine Rupture:  a full-thickness separation of the uterine wall and the overlying serosa.

  • Increased use of interventions including pain relief, continuous fetal monitoring and other interventions. When labor is induced babies tend to stay in unfavorable positions, the use of epidural anesthesia is increased and therefore the need to assist the baby's birth via the use of forceps and vacuum extraction is also increased.  Being born even a week or two early can result in your baby being a near term or late preterm infant. This means that your baby is likely to have more trouble breathing, eating and maintaining temperature.

The risks can be considerably lowered both for mother and baby with the spontaneous onset of labor between 38 and 39 weeks.

Induction of labor has recently been on the rise for purposes of convenience or to accommodate busy schedules. However, according to the American College of Obstetricians and Gynecologists (ACOG), labor should be induced only when it is more risky for the baby to remain inside the mother's uterus than to be born. 
 


Medical Reasons for Labor Induction

Increased Chances of Birth Complications with Elective InductionLabor can be induced for many reasons. Labor should only be induced for valid medical reasons because of the risks involved with induction of labor.

Possible indications for labor induction include gestational or chronic hypertension, preeclampsia, eclampsia, diabetes, premature rupture of membranes, severe fetal growth restriction, and post-term pregnancy(42 weeks completed). However, physicians should decide whether labor induction is warranted on individual basis, after consideration of maternal and infant conditions, cervical status, gestational age, and other factors.


 

Contraindications to labor induction include transverse fetal position, umbilical cord prolapse, active genital herpes infection, placenta previa, and a history of previous myo-mectomy.

When labor induction is deemed necessary, the gestational age of the fetus should be determined to be at least 39 weeks, or there must be evidence of fetal lung maturity.
 


The first step in labor induction is cervical ripening using drugs or mechanical cervical dilators to dilate the cervix sufficiently before labor is induced. The next step is to induce labor using oxytocin, membrane stripping, rupture of the amniotic membrane, or nipple stimulation.
 

Misoprostol, which is approved for treatment of peptic ulcers, is often used off-label for cervical ripening as well as for labor induction. In women who have had any previous cesarean delivery, however, inducing labor with misoprostol may increase risk for uterine rupture and should therefore be avoided.
 

The result of the study suggest that for women whose pregnancy is uncomplicated, awaiting the spontaneous onset of labor is best.
