Epidurals and Birth Injuries

Epidurals are the most widely used method of pain relief during labor and delivery in the United States. While they are generally safe and effective, parents often have questions about how epidurals might affect their baby, particularly when it comes to the risk of birth injuries. Understanding the connection between epidural use and newborn outcomes can help families make informed decisions during labor and recognize when additional monitoring or care may be needed.

This page explains what epidurals are, how they work, their benefits and risks, and what families should know about potential effects on labor and newborn health.

What is an Epidural?

An epidural, also called labor neuraxial analgesia, is a form of regional anesthesia that provides pain relief during labor and delivery. It involves placing a thin catheter into the epidural space in the lower back, through which anesthetic and opioid medications are continuously delivered. This blocks pain signals from the lower body while allowing the mother to remain awake and alert.

Epidurals are used in about 60% of births in the United States and are considered the gold standard for labor pain management. They can be used for both vaginal deliveries and cesarean sections, and they allow for adjustments in medication dosage as labor progresses.

Benefits of Epidurals

Epidurals offer significant advantages for laboring women, particularly those experiencing long or difficult labors. The primary benefits include:

Effective pain relief. Epidurals provide profound and consistent pain control, often allowing mothers to rest and conserve energy during labor.

Reduced maternal stress. By controlling pain, epidurals can lower the release of stress hormones like catecholamines, which may otherwise interfere with labor progress and fetal oxygen supply.

Blood pressure management. In women with high blood pressure, epidurals can help lower blood pressure during labor.

Reduced risk of severe maternal complications. Large studies have shown that epidurals are associated with a lower risk of severe maternal morbidity when compared to unmedicated birth or general anesthesia.

When administered by trained providers and monitored carefully, epidurals are generally well tolerated and safe for both mother and baby.

How Epidurals Can Influence Labor and Delivery

While epidurals are not directly linked to severe or permanent birth injuries, they can influence certain aspects of labor that may indirectly affect newborn outcomes. These effects are typically related to changes in labor dynamics and maternal physiology rather than the medication itself.

Maternal Hypotension

One of the most common side effects of epidural anesthesia is a drop in maternal blood pressure. This happens because the medication causes blood vessels to relax. When blood pressure drops, blood flow to the placenta may temporarily decrease, which can reduce oxygen delivery to the baby.

Maternal hypotension can lead to changes in the fetal heart rate, including decelerations that may require intervention. Medical staff routinely monitor blood pressure after epidural placement and treat low blood pressure quickly with fluids and medications to restore normal circulation.

Prolonged Labor

Epidurals can lengthen the second stage of labor, which is the pushing phase. This occurs because the medication may reduce the mother’s ability to feel the urge to push or weaken the pelvic floor muscles involved in delivery. A longer second stage increases the likelihood that assisted delivery methods, such as forceps or vacuum extraction, may be needed.

Increased Use of Assisted Delivery

Studies consistently show that women who receive epidurals are more likely in some populations to require forceps or vacuum assistance during delivery. These instruments are used when the baby needs help descending through the birth canal, often due to fetal distress or difficulty with pushing.

Assisted deliveries carry a higher risk of certain birth injuries, including brachial plexus injuries, facial nerve palsy, and scalp injuries such as cephalohematoma. These injuries are related to the mechanical forces of the instruments rather than the epidural medication itself.

Maternal Fever

Epidurals are associated with a higher rate of maternal fever during labor. The exact reason for this is not fully understood, but it may be related to changes in temperature regulation or an inflammatory response. When a mother develops a fever, her baby is more likely to be evaluated for possible infection after birth, which may include blood tests, antibiotic treatment, and admission to the neonatal intensive care unit.

Potential Effects on Newborns

Most babies born to mothers who used epidurals do well and experience no lasting harm. However, research has identified some short term effects and temporary complications that are more common after epidural use.

Respiratory Distress

Newborns exposed to epidurals during labor are slightly more likely to experience transient respiratory difficulties at birth, including the need for supplemental oxygen or positive pressure ventilation. These effects are usually mild and resolve quickly, but they may prompt closer observation or brief NICU admission.

NICU Admission and Early Complications

Several studies have found higher rates of NICU admission among babies whose mothers received epidurals. This is often related to respiratory distress, low body temperature at birth, or evaluation for possible infection when maternal fever is present. Most of these admissions are precautionary, and the majority of babies are discharged home without long term concerns.

Birth Injuries

A large cohort study found that babies born to mothers who used epidurals had a higher rate of birth injuries, with an odds ratio of 1.71. The most common injuries included shoulder dystocia, facial nerve palsy, and cephalohematoma. These injuries were primarily associated with the increased use of forceps and vacuum extraction rather than direct effects of the epidural medication.

It is important to note that most birth injuries related to assisted delivery are temporary and resolve with time or supportive care. Serious or permanent injuries remain rare.

No Increased Risk of Long Term Harm

Research to date does not show a strong link between epidural use and permanent neurological injuries such as cerebral palsy. Apgar scores, which measure a baby’s overall condition at birth, are generally not significantly different between babies exposed to epidurals and those who are not.

Prevention and Safe Use of Epidurals

Modern obstetric care includes multiple safeguards to minimize risks associated with epidural use. Hospitals and providers follow established protocols to ensure safe administration and careful monitoring throughout labor.

Monitoring and Management

Standard care includes continuous monitoring of maternal blood pressure, heart rate, and fetal heart rate before, during, and after epidural placement. If maternal hypotension or fetal heart rate changes occur, medical staff respond quickly with interventions such as intravenous fluids, position changes, or medications to restore normal circulation.

Informed Consent and Counseling

The American College of Obstetricians and Gynecologists recommends that providers discuss the benefits, risks, and alternatives to epidurals with patients during prenatal care and early labor. This allows families to make informed decisions based on their individual health needs and preferences.

Lowest Effective Dose

Providers aim to use the lowest effective dose of medication to achieve pain relief while minimizing side effects. Modern epidurals often use a combination of local anesthetics and opioids, which allows for better pain control with fewer motor effects.

Avoiding High Risk Situations

Epidurals may be delayed or avoided in certain situations where risks are higher, such as in women with active infections, bleeding disorders, or severe blood pressure abnormalities. Providers assess each patient individually to determine the safest approach.

Support and Follow Up for Families

If your baby experienced complications related to labor or delivery, follow up care and support are available to help ensure the best possible outcome.

NICU and Developmental Care

Babies who are admitted to the NICU after instrumental delivery or respiratory distress receive close monitoring and specialized care. Most infants with temporary complications recover fully and do not require long term intervention. However, some babies may benefit from developmental follow up to monitor milestones and address any concerns early.

Education and Resources

Families benefit from clear, compassionate information about pain relief options during labor. Prenatal classes, conversations with healthcare providers, and trusted resources can help parents weigh the benefits and risks of epidurals and other pain management methods.
