Preterm Labor

Preterm or premature labor is when there are contractions and cervical changes before 37 weeks gestation. Preterm labor is diagnosed when contractions begin and intensify between the 20th and 37th week of gestation. Preterm labor can lead to the birth of a premature baby or the birth of a baby that is not viable if born before the 27th week of gestation.Preterm labor

Why Does Preterm Labor Happen?
In most cases of preterm labor, the contractions begin spontaneously and without definitive cause. Women are often at greater risk of going into preterm labor if mom:

  • Has certain medical issues
  • Experiences problems during the pregnancy related to the placenta, blood pressure or amniotic sac.
  • Has an infection
  • Has a history of preterm labor.
  • Is pregnant with multiples.
  • Is under 18 years of age.
  • Is older or had IVF
  • Chooses to smoke or use recreational drugs during pregnancy.

How Do You Know it is Preterm Labor?
Many women who go into preterm labor feel the contractions are simply Braxton Hicks contractions. Braxton Hicks contractions are exercises for the uterus used by the body to prepare the uterus for labor.

Braxton Hicks contractions will appear and disappear at no common interval. Preterm labor, on the other hand, will present with rhythmic contractions, increased vaginal discharge, breaking of the bag of waters, lower back pain and cramps of the abdomen.

If you feels any contractions before 37 weeks it's best to call your doctor and get examined to find out if it's labor or not.

Patients presenting with the symptoms of preterm labor will be given a pelvic exam and placed on a fetal monitor to measure the strength of the contractions.

Can Preterm Labor Be Stopped?
The simple answer to this question is, sometimes, but not always. Pregnant moms, especially those who are pregnant with multiples, will feel aches and pains all the time. In cases of preterm labor, the symptoms may be so mild at first that they are brushed off as common pregnancy pains. Once the cervix begins to dilate or the mucus plug falls out, the doctor may not be able to stop the preterm labor.

There are cases, however, where moms do not feel the contractions but they are noted on ultrasound or during the normal prenatal checkup. If preterm labor is detected early enough, there are some medications that can be prescribed to stop the contractions, though sometimes they are too risky to give. These medications can be administered in both pill and IV form.

Once preterm labor has been stopped, mom will be told to maintain 100% bed rest until the time comes to deliver baby. If the labor was strong, the doctor may prescribe a corticosteroid to help the babies lungs develop in time for an early delivery. Bed rest is especially important for the health of baby. The longer the baby can stay in the womb, the stronger the baby will be upon birth. Doctors may admit mom to the hospital if they feel she will not be able to rest at home or if IV medication is required to stop labor.

Can you improve the Baby's outcome?
Complications to the baby of the premature birth include lung issues, bowel issues, and brain issues. If there is a preterm labor prior to 34 weeks and delivery is still not imminent, doctors usually give a medication (corticosteriod) to improve the baby's outcome after birth. However, this medication needs at least 12-24 hours to be effective and if delivery is imminent it won't help giving this medication.  

Preterm labor offers a unique set of challenges for both mom and baby. If the baby is born too early, they may not be ready to live outside of the womb and may require extensive treatment before going home.
