Can Prolonged Labor Cause Birth Injuries? What Parents Should Know

Prolonged labor can cause birth injuries when a baby is exposed to ongoing stress, reduced oxygen, fetal distress, or a difficult delivery that is not handled in time. A long labor does not automatically mean malpractice or permanent injury, but it can raise concern when the baby had abnormal heart rate patterns, low Apgar scores, trouble breathing, seizures, or signs of hypoxic-ischemic encephalopathy after birth. In New York, parents who suspect a preventable birth injury usually need the delivery records reviewed to understand what happened and whether earlier action should have been taken.

A long labor can be frightening because parents often do not know what is normal and what is not. Some labors naturally take longer, especially for first-time mothers. Other long labors happen because the baby is not descending, contractions are not strong enough, the baby is in a difficult position, or the birth canal and the baby’s size do not match well.

The key question is not only how long labor lasted. The more important question is whether the medical team recognized signs of trouble and responded appropriately.

Can prolonged labor cause birth injuries

Prolonged labor can contribute to birth injuries when the baby remains under stress for too long or when doctors delay necessary intervention. Birth injuries linked to a difficult or prolonged labor may involve oxygen deprivation, birth asphyxia, HIE, brachial plexus injuries, skull or scalp injuries, fractures, or complications after forceps or vacuum delivery.

According to StatPearls, neonatal birth trauma can include head trauma, intracranial hemorrhage, brachial plexus injuries, broken bones, and injury related to decreased oxygenation to the fetal brain. The same source lists labor dystocia, difficult fetal extraction, vacuum or forceps use, and prolonged labor among risk factors for birth trauma.

This does not mean every long labor is dangerous. Some babies tolerate long labor well. Others begin showing signs that they are not getting enough oxygen or are struggling with the stress of delivery. That is why fetal monitoring, clinical judgment, and timely delivery decisions matter.

What prolonged labor means during delivery

Prolonged labor generally means labor is taking longer than expected or is not progressing normally. Doctors may describe this as slow labor, labor dystocia, prolonged second stage, failure to progress, or arrest of labor.

The first stage of labor involves cervical dilation. The second stage begins when the cervix is fully dilated and ends when the baby is delivered. A prolonged second stage is especially important because the baby may be under pressure for a longer period while moving through the birth canal.

Doctors do not usually decide that labor is unsafe based on time alone. They consider several factors, including:

• The baby’s heart rate
• The mother’s contractions
• The baby’s position
• How far the baby has descended
• Whether the mother and baby are stable
• Whether labor is continuing to progress
• Whether forceps, vacuum extraction, or C-section may be safer

ACOG’s 2024 guidance on first and second stage labor management addresses definitions for labor arrest and management of dystocia, which are central issues when labor is not progressing normally.

How prolonged labor can affect a baby

Prolonged labor can affect a baby in several different ways. The most serious concerns involve oxygen deprivation, fetal distress, birth asphyxia, HIE, and physical trauma from pressure or assisted delivery.

A baby depends on steady oxygen and blood flow through the placenta and umbilical cord during labor. If labor complications interfere with that oxygen supply, the baby may show warning signs before delivery or appear distressed immediately after birth.

Some babies recover quickly after a difficult labor. Others need resuscitation, NICU care, cooling therapy, neurological evaluation, imaging, or long-term monitoring.

Oxygen deprivation during a long labor

Oxygen deprivation can happen when the baby does not receive enough oxygen before, during, or shortly after delivery. In a long labor, this concern may arise if contractions, cord compression, placental problems, uterine rupture, or other complications reduce oxygen and blood flow.

MSD Manual explains that birth asphyxia is a decrease in oxygen in a newborn’s blood or blood flow to the newborn’s tissues before, during, or just after delivery. It may involve low Apgar scores, weak breathing, poor circulation, or the need for resuscitation after birth.

Oxygen deprivation is not always caused by prolonged labor itself. The longer labor lasts, however, the more important it becomes for doctors and nurses to watch for signs that the baby is no longer tolerating labor well.

Fetal distress during prolonged labor

Fetal distress means there are signs before or during childbirth that the baby may not be doing well. One of the most common warning signs is an abnormal fetal heart rate pattern.

Merck Manual explains that fetal distress often occurs when the fetus has not been receiving enough oxygen, and doctors usually identify it through fetal heart rate monitoring during labor.

Parents may hear nurses or doctors mention decelerations, late decelerations, minimal variability, nonreassuring tracing, or Category II or Category III fetal heart rate patterns. These terms can sound confusing, but they generally relate to how the baby’s heart rate is responding to contractions and stress.

When concerning fetal heart rate patterns continue, the medical team may need to reposition the mother, give fluids, adjust medications, stop labor-stimulating drugs, call for additional help, or move toward delivery.

Birth asphyxia and HIE after a difficult delivery

Birth asphyxia can occur when oxygen or blood flow is disrupted around the time of birth. If the baby’s brain is affected by that oxygen and blood flow problem, doctors may diagnose hypoxic-ischemic encephalopathy, also called HIE.

StatPearls explains that perinatal asphyxia can cause systemic and neurologic complications because reduced blood flow and oxygen affect vital organs. It also explains that neonatal HIE refers to the neurologic injury that results from perinatal asphyxia and ischemia.

Signs that may raise concern for HIE after prolonged labor include:

• Seizures
• Very low Apgar scores
• Trouble breathing
• Poor muscle tone
• Weak or absent suck
• Abnormal alertness
• Need for resuscitation
• Metabolic acidosis
• Abnormal MRI findings
• NICU admission for neurological monitoring

Not every baby with low Apgar scores has HIE. Not every baby with HIE was harmed by malpractice. The delivery timeline, fetal monitoring strips, cord blood gases, newborn exam, imaging, and NICU records usually need to be reviewed together.

Physical injuries from pressure or assisted delivery

Prolonged labor can also increase the risk of some physical injuries, especially when the baby is stuck, positioned awkwardly, or delivered with forceps or vacuum assistance.

One example is cephalohematoma, which is bleeding under the scalp that may appear as a swelling on the baby’s head. StatPearls lists prolonged second stage of labor, large baby size, weak contractions, abnormal fetal presentation, and forceps or vacuum delivery as risk factors for cephalohematoma.

Other possible physical injuries after a difficult labor may include bruising, caput succedaneum, skull fracture, clavicle fracture, facial nerve injury, brachial plexus injury, or shoulder dystocia-related trauma.

Some of these injuries heal with observation and time. Others may require imaging, therapy, specialist care, or long-term follow-up.

When prolonged labor may become dangerous

Prolonged labor may become dangerous when the baby shows signs of distress, labor stops progressing, or the delivery plan does not change despite growing risk. Doctors are expected to monitor both mother and baby and adjust the plan when the situation changes.

Warning signs during labor may include:

• Persistent abnormal fetal heart rate patterns
• Repeated decelerations after contractions
• Meconium-stained fluid
• Maternal fever or suspected infection
• Uterine rupture concerns
• Placental abruption concerns
• Umbilical cord problems
• Arrest of labor
• Failed vacuum or forceps attempt
• Baby not descending despite strong contractions

Parents are not expected to diagnose these problems during labor. These are clinical issues for the medical team. Still, if you remember repeated concerns about the baby’s heart rate, emergency movement in the room, or a sudden C-section after hours of stalled labor, those details may matter later.

When a delayed C-section may become a concern

A delayed C-section may become a concern when labor is not progressing and the baby is showing signs that continued labor may be unsafe. C-sections are not risk-free, so doctors do not perform them simply because labor is long. The concern is whether a C-section became necessary and was delayed despite warning signs.

Situations that may raise questions include:

• The baby’s heart rate was abnormal for an extended period
• The baby was not descending
• The mother was told the baby was stuck
• Labor-stimulating medication was continued despite fetal distress
• Forceps or vacuum were attempted when a C-section may have been safer
• The baby needed resuscitation after birth
• The baby was diagnosed with birth asphyxia, HIE, seizures, or brain injury

A difficult outcome does not prove negligence. The medical records are what show whether the team followed accepted standards, responded to warning signs, and delivered the baby within a reasonable time once intervention became necessary.

How doctors should respond when labor is not progressing

When labor is not progressing, doctors and nurses should monitor the mother and baby closely and reassess whether the current plan remains safe. The response depends on the stage of labor, the baby’s condition, the mother’s condition, and whether there is still safe progress.

A medical team may respond by:

1. Checking fetal heart rate patterns
2. Repositioning the mother
3. Giving IV fluids or other supportive care
4. Evaluating contraction strength
5. Adjusting or stopping labor-inducing medication
6. Assessing the baby’s position and descent
7. Considering assisted delivery when appropriate
8. Moving to C-section when vaginal delivery is no longer safe

The timing matters. A decision that is reasonable early in labor may become unreasonable later if the baby begins showing signs of distress or if progress stops.

What parents may notice after prolonged labor

Parents may not know something went wrong until after delivery. Some signs are obvious immediately. Others appear hours, days, or months later.

After prolonged labor, parents should ask questions if the baby has:

• Low Apgar scores
• Trouble breathing
• Need for resuscitation
• NICU admission
• Seizures
• Poor feeding
• Limpness or unusual stiffness
• Weak cry
• Abnormal movements
• Abnormal head swelling
• Jaundice concerns after scalp bleeding
• Delayed milestones later in infancy

Some of these signs can happen for reasons unrelated to negligence. The important thing is to document what you were told, keep copies of discharge papers, attend follow-up appointments, and ask the pediatrician whether specialist evaluation is needed.

What New York parents can do if they suspect a birth injury

New York parents who suspect prolonged labor contributed to a birth injury should start by collecting the medical records and asking for a clear explanation of what happened. The most important records usually include fetal monitoring strips, labor and delivery notes, medication records, operative reports, newborn records, cord blood gas results, NICU notes, imaging, and discharge summaries.

For potential New York birth injury claims involving medical malpractice, timing can matter. CPLR § 208 includes an infancy toll, but New York law generally does not allow that toll to extend medical malpractice claims beyond 10 years from the malpractice date.

Families should not wait until a deadline is close to ask questions. Birth injury cases often require review by qualified medical experts, and the attorney may need time to obtain and analyze records before knowing whether there is a legal claim.

Questions to ask if you are worried about prolonged labor

Parents can ask direct, practical questions after a difficult labor. These questions may help clarify whether the baby was simply monitored after a hard delivery or whether there were signs of a more serious injury.

Helpful questions include:

• Why did labor take so long?
• Was there arrest of labor or failure to progress?
• Were there abnormal fetal heart rate patterns?
• Did the baby show signs of fetal distress?
• Was a C-section considered?
• Why was a C-section not performed earlier?
• Were forceps or vacuum used?
• What were the Apgar scores?
• Were cord blood gases taken?
• Why did the baby need NICU care?
• Should my baby see a neurologist?
• Should we watch for developmental delays?

If the answers feel incomplete, parents can request the full medical records and seek a second opinion.

Frequently asked questions

Can prolonged labor cause brain injury

Prolonged labor can contribute to brain injury if the baby experiences significant oxygen deprivation or reduced blood flow during delivery. The concern is not just that labor lasted a long time. The concern is whether the baby showed signs of fetal distress, birth asphyxia, seizures, abnormal cord blood gases, or HIE, and whether those signs were recognized and handled in time. Merck notes that fetal distress is often identified through abnormal fetal heart rate patterns during labor.

Can prolonged labor cause HIE

Prolonged labor can be part of the events leading to HIE when the baby experiences reduced oxygen and blood flow around birth. HIE means the baby’s brain was affected by oxygen deprivation and impaired blood flow. Doctors usually look at fetal monitoring, Apgar scores, cord blood gases, neurological signs, seizures, MRI findings, and the newborn’s condition after delivery to understand whether HIE occurred.

Does prolonged labor always mean malpractice

Prolonged labor does not always mean malpractice. Some labors are long but still safely managed. A legal concern is more likely when warning signs were missed, fetal distress was not acted on, a C-section was delayed despite clear risk, or forceps or vacuum were used in a way that caused injury. The records usually determine whether care was appropriate.

Can delayed C-section after prolonged labor cause birth injury

A delayed C-section can contribute to birth injury if the baby needed to be delivered sooner because of fetal distress, oxygen deprivation, arrest of labor, or another complication. ACOG’s 2024 labor guidance discusses labor arrest and management of difficult first and second stage labor, which are often central issues when labor is not progressing normally.

How long do New York parents have to ask about a birth injury case

New York timing rules depend on the claim, hospital, and facts. For medical malpractice involving a child, CPLR § 208 generally does not allow infancy tolling to extend the claim beyond 10 years from the malpractice date. Cases involving public hospitals may also have shorter notice requirements. Parents should ask for legal guidance early because record review and expert analysis take time.

Final reminder

A long labor can be exhausting and frightening, but it does not always mean something was done wrong. The real concern is whether the baby showed signs of distress, whether those signs were recognized, and whether the medical team responded in time. If your child had complications after prolonged labor, start with medical follow-up, keep copies of the records, and ask clear questions about what happened during delivery.
