Preterm Labor

Pre Term Labor Symptoms, PreTerm Labor, Menopause Center Los AngelesPreterm labor is defined as labor that begins earlier than 37 weeks into the pregnancy. If the baby is born between 20 and 37 weeks, it is considered a preterm birth.

When a woman enters preterm labor, the contractions cause the cervix to thin out, and/or dilate early.

Preterm birth can result in serious consequences. The baby may not have had enough time in the womb to reach its full growth potential. Essential organs and systems may not be ready to sustain the baby outside its mother without medical intervention.

The earlier the baby is born, the greater the risk for complications. Some babies born prematurely have serious health problems, like cerebral palsy and other long-term physical and learning disabilities.

Risk Factors for Preterm Birth

Some pregnancies have a higher risk for preterm birth than others. Factors that increase the risk include:

  • Being underweight during the pregnancy
  • Smoking, drug, or alcohol abuse during pregnancy
  • Having a history of preterm birth
  • When it’s been less than two years since the last pregnancy
  • Having a short cervix
  • Prior surgery on the cervix or uterus
  • Multiple pregnancy
  • Vaginal bleeding 

Can I Reduce My Risk for Preterm Birth?

There’s no 100% foolproof method for preventing a preterm birth. Your physician can assess your risk, and give you a set of precautionary measures to follow.

If you are at risk, your doctor may refer you to a specialist in high-risk pregnancies. There are some medications available to help prevent some preterm births, but these prescriptions are made on a case-by-case basis.

Symptoms of Preterm Labor

Preterm labor requires immediate attention. Please call your doctor right away if you have one or more of these symptoms.

  • Dull aches in the lower back
  • Cramping
  • Diarrhea
  • Contractions or uterine tightening at regular intervals, with or without pain

What Will Happen if I go into Preterm Labor?

High-Risk Obstetrics, PreTerm Labor, Menopause Center Los AngelesYour doctor will perform diagnostic tests and a series of pelvic exams. A transvaginal ultrasound can check the dilation of the cervix.

Your doctor will also want to test your vaginal discharge for fetal fibronectin, which is a protein commonly found in preterm births. Based on the results, you may need to be hospitalized, or visit a specialist immediately.

Even after testing, it may still be unclear whether preterm labor will progress to preterm birth.

In fact, only 10% of women who enter preterm labor go on to give birth in the next week. You may receive treatment to delay labor, but for 1/3 of women, preterm labor ends naturally. .

However, if preterm labor does continue, your doctor will provide you with individualized instructions to protect your health and the health of your baby.

What Treatments are Available for Preterm Labor?

Medications may be prescribed to handle your specific case and promote a healthy birthing outcome. Common treatments include:

Corticosteroids

These are drugs injected into the placenta, and are designed to accelerate the growth of the baby’s brain, lungs, and digestive system. They can help to increase your baby’s chance of survival outside the womb should a preterm birth occur. Typically, these drugs are given between 24 and 34 weeks of pregnancy.

Magnesium Sulfate

If you are at 31 weeks or less, and are at risk of delivering the baby within the next day or so, magnesium sulfate can reduce the risk of cerebral palsy, which is a common complication of preterm birth.

Tocolytics

These drugs can delay delivery for up to two days. They may be used to increase the amount of time for magnesium sulfate and corticosteroids to do their work.

There are times when preterm birth cannot be avoided. If this is the case, you should expect the highest standard of care from a specialized team of maternity experts, including a neonatologist. Your baby may spend time in the Neonatal Intensive Care Unit (NICU) until she is strong enough to survive on her own.
