What Signs Indicate My Baby Is In Distress? How Is Fetal Distress Treated?

Fetal distress is an emergency pregnancy, labor, and delivery complication in which a baby experiences oxygen deprivation (birth asphyxia), causing changes in the baby’s heart rate, decreased fetal movement, and abnormal substances in the amniotic fluid. A fetal heart rate monitor will detect the presence of abnormal fetal heart rate tracings in the presence of fetal distress. Medical professionals must immediately address and manage fetal distress to avoid hypoxic-ischemic encephalopathy (HIE) and permanent injury. Expectant mothers aren’t always with their physician when signs of fetal distress occur, so it is important to know the following signs that indicate a baby is in trouble. Often, the only way to stop fetal distress is to deliver a baby, allowing doctors and nurses to administer medical care. This frequently is accomplished by C-section delivery.

Fetal Distress

Signs of Fetal Distress

1. Signs of Fetal Distress: Decreased Fetal Movement in the Womb

Fetal movement within the mother’s womb is one of the most exciting parts of pregnancy. Beyond bringing joy to the family, movement within the womb is an important indicator of the baby’s health. Some regular pauses in movement are normal because babies sleep in the womb. However, if the baby becomes less active or completely ceases to move, this may be a cause for concern. Physicians should ask expectant mothers about fetal movement and conduct additional testing if patterns are abnormal.

2. Signs of Fetal Distress: Abnormal Fetal Heart Rate

Some fetal heart rate patterns indicate distress. To observe an unborn baby’s heart rate, medical professionals can use either an external or internal fetal monitoring device. External monitoring is done through a belt-like device that can be strapped around a mother’s abdomen, while internal monitoring involves attaching an electrode to the baby’s scalp. In a healthy labor and delivery, the baby’s heart rate will drop slightly during a contraction, and then quickly return to normal once the contraction is over. Therefore, some variability in heart rate is to be expected: this shows as a jagged line on the monitor. The following fetal heart rate patterns are nonreassuring and warrant further investigation and possibly medical intervention:

  • An abnormally fast heart rate (tachycardia)
  • An abnormally slow heart rate (bradycardia)
  • Abrupt decreases in heart rate (variable decelerations)
  • Late returns to the baseline heart rate after a contraction (late decelerations)

In addition to fetal monitoring, an abnormal fetal heart rate may be recognized in a non-stress test (NST) or a contraction stress test (CST).

During an NST, a medical professional looks at how the heart rate fluctuates. A normal NST is called “reactive,” meaning that the baby’s heart rate went up and down as expected. “Non-reactive” means that the baby’s heart rate did not increase enough at times. Physicians may also classify NST results into categories:

  1. Normal
  2. Requiring further testing and possibly delivery
  3. An emergency C-section is necessary

A CST helps to predict how the baby will cope during the labor process, and determine whether it is safe to proceed with a vaginal delivery. Uterine contractions temporarily restrict oxygen flow; this is something a healthy baby can tolerate, but it may be very dangerous for a baby in distress. During a CST, physicians record the baby’s heart rate in response to contractions. If conducting a CST on a woman not yet in labor, the physician may give her Pitocin (synthetic oxytocin), to make the uterus contract. It is important to note that there are certain risks associated with this. Pitocin can cause uterine tachysystole (excessively strong, frequent, or long contractions); this can severely restrict oxygen flow to the baby and sometimes leads to uterine rupture.

3. Signs of Fetal Distress: Abnormal Amniotic Fluid Level

An ultrasound can obtain a measurement called the amniotic fluid index, or AFI. The AFI is calculated by measuring the depth of the amniotic fluid in four sections of the womb and adding the numbers together. Near-term, an AFI of 5 cm or below is considered abnormally low and indicates that the baby has a condition called oligohydramnios, which can lead to oxygen deprivation and birth injuries like HIE and cerebral palsy (CP). A sudden decrease in amniotic fluid may also warn of oligohydramnios, even if the AFI is above 5 cm. An AFI of 5.1-8 or 9 cm is considered “borderline” for oligohydramnios and should be watched closely. An AFI that is abnormally high, defined as 24 or more centimeters, is a sign of polyhydramnios (excessive amniotic fluid). Polyhydramnios can also cause oxygen deprivation and subsequent birth injuries.


4. Signs of Fetal Distress: Abnormal Results of Biophysical Profile (BPP)

A baby’s biophysical profile (BPP) is also often taken if the results of an NST are nonreassuring. In addition to taking into account NST results, the BPP includes an ultrasound to assess fetal movement, breathing, tone, and amniotic fluid volume. The nonstress test and each of the four ultrasound parameters are assigned a score of either zero or two points. A total score of eight or higher is considered normal unless the zero score relates to low amniotic fluid. A score of four or lower indicates fetal distress and requires immediate action.

5. Signs of Fetal Distress: Vaginal Bleeding

Small amounts of vaginal bleeding are fairly common during pregnancy.  However, bleeding can be an indication that something is wrong with the pregnancy, such as the presence of placental abruption, placenta previa, or vasa previa. Placental abruption occurs when the placenta tears away from the womb. Depending on the location and size of the abruption, it may not initially cause distress in the baby. However, a small tear can increase in size and cause distress, and it also can become a large and serious tear very quickly.

It is important to note that a placental abruption can also be present with no vaginal bleeding (bleeding can be hidden), but if a mother experiences vaginal bleeding, the physician should be notified so that a proper assessment can be done to ensure that the baby is receiving enough oxygen. The physician should perform an ultrasound to check for abruption, and the baby’s heart rate should be checked to ensure fetal distress is not present.

A placental abruption and other placental problems that cause bleeding require very close monitoring, and in many cases, the mother should be admitted to the hospital and given an emergency C-section.

6. Signs of Fetal Distress: Cramping

Some cramping is relatively normal during pregnancy. This is because as the baby grows, the uterus needs to expand. However, cramping should be discussed with the physician as soon as it occurs – especially if the cramping is intense – to make sure that there is nothing wrong. Cramping could be an indication of many things, including placental abruption. Cramps are especially concerning if back pain also is present. It is crucial that physicians appreciate cramping and perform proper tests to ensure the health of the mother and baby and to make sure that problems such as placental abruption are not present.

7. Signs of Fetal Distress: Insufficient or Excessive Maternal Weight Gain

Experts believe that a weight gain of anywhere between 20 and 40 pounds is normal during pregnancy. If a mother gains much less than that, the fetus may be in distress and have a condition called intrauterine growth restriction (IUGR), which means they are smaller than is developmentally appropriate (among other problems).  IUGR requires careful physician monitoring and testing, and early delivery prior to labor. A mother should have regular prenatal visits, and her physician should know that abnormal weight changes may necessitate additional fetal monitoring.

Excessive maternal weight gain is associated with giving birth to a baby that is abnormally large, which is a condition known as macrosomia. Macrosomia can be very dangerous for a baby. Macrosomia can create a risky birth situation, such as cephalopelvic disproportion (CPD), wherein the mother’s pelvis is too small to accommodate the size of the baby’s head, or shoulder dystocia, which is when the baby’s shoulder gets stuck on the mother’s pelvic bone during delivery. Macrosomia is especially dangerous if the physician is unaware of the condition. A physician in this situation may try to deliver the baby vaginally, and when delivery doesn’t progress the way it should (and it won’t if CPD or shoulder dystocia are present), the physician may use dangerous delivery devices. These may include birth-assisting tools like forceps and vacuum extractors, or labor induction drugs, such as Pitocin and Cytotec. Forceps and vacuum extractors can cause head trauma and brain bleeds, and labor induction drugs can cause contractions to be so strong, long, and frequent that the baby becomes deprived of oxygen. Oxygen deprivation and brain bleeds can cause permanent brain damage in a baby and resultant hypoxic-ischemic encephalopathy, cerebral palsy, periventricular leukomalacia (PVL), and developmental delays. Typically, the best way to deliver a macrosomic baby is by C-section.

A Note on Terminology

The American College of Obstetricians and Gynecologists (ACOG) cautions that the term fetal distress is “imprecise and nonspecific.” Instead, they recommend that “fetal distress” be replaced with “nonreassuring fetal status,” and be accompanied by a more detailed description of the baby’s health.

Regardless of what terminology they prefer, it is important that medical professionals be very familiar with specific warning signs of fetal oxygen deprivation in order to prevent permanent harm.

Causes of Fetal Distress

The following are just a few underlying causes of fetal distress:

Treating Fetal Distress

The medical team must skillfully and continuously monitor fetal well-being throughout pregnancy, labor, and delivery. They are responsible for recognizing and responding to signs of fetal distress. If a baby is in distress, appropriate interventions may include the administration of oxygen, fluids, and medication to the mother, or a change in the mother’s position. Often, an emergency C-section is required in order to remove the baby from the conditions causing the fetal distress, especially if earlier interventions did not cause fetal heart tones to become reassuring.  An emergency C-section should be performed within 18 minutes, depending on the circumstances, and sometimes a lot sooner.

Mismanaged Fetal Distress, Birth Injury, and Medical MalpracticeC-section; cesarean section; surgical birth; pregnancy; baby; emergency C-section

Signs of fetal distress should always be taken seriously. It is critical that medical professionals promptly recognize and address these signs (which may include interventions such as an emergency C-section) in order to prevent permanent injury and disability in a newborn baby. They must be especially careful in assessing maternal and fetal health in high-risk pregnancies. If physicians dismiss signs of fetal distress or fail to follow standards of care for high-risk pregnancies, this constitutes medical negligence. If this negligence leads to injury, it is medical malpractice.
