Meconium Aspiration in Kentucky Births

Morrin Law Office
C

When doctors or nurses say that there was meconium in the amniotic fluid, parents may immediately worry that their baby swallowed or inhaled stool during delivery.

Meconium-stained amniotic fluid and meconium aspiration syndrome (MAS) are related, but they are not the same thing.

Many babies are born through meconium-stained fluid and never develop serious respiratory problems.

Meconium aspiration syndrome occurs when a newborn exposed to meconium develops respiratory distress associated with meconium in the lungs. Severe cases can require oxygen, mechanical ventilation, neonatal intensive care, treatment for persistent pulmonary hypertension of the newborn (PPHN), or, in rare critical cases, extracorporeal membrane oxygenation (ECMO).

An MAS diagnosis also does not automatically mean that an obstetrician, nurse, pediatrician, or hospital committed malpractice.

A meaningful Kentucky birth injury investigation generally asks:

  • Why was meconium present?
  • What did the fetal heart rate tracing show?
  • Was an appropriately skilled newborn-resuscitation team available?
  • How was the baby breathing immediately after birth?
  • Was ventilation started when needed?
  • Was unnecessary suctioning allowed to delay ventilation?
  • Was there an actual airway obstruction that required suctioning?
  • When did respiratory distress become apparent?
  • Did the baby develop PPHN or another complication?
  • Was NICU treatment or transfer handled appropriately?
  • Did the child suffer a lasting injury?

This guide explains those questions, the current newborn-resuscitation guidance, records that may matter, and Kentucky legal rules that can apply to a serious MAS birth injury claim.

What Is Meconium?

Meconium is the dark, thick material that forms in a baby’s intestines before birth and normally becomes the baby’s first stool.

Sometimes a fetus passes meconium before or during labor.

When that happens, the amniotic fluid may appear:

  • Green
  • Yellow-green
  • Brownish
  • Thinly stained
  • Thick or particulate

This is known as meconium-stained amniotic fluid, or MSAF.

Meconium-stained fluid becomes more common as gestational age increases and is particularly associated with term and post-term pregnancy.

But the presence of meconium does not automatically mean that the fetus was deprived of oxygen.

Does Meconium-Stained Fluid Mean the Baby Was in Distress?

Not necessarily.

Research has associated meconium-stained amniotic fluid with fetal stress, hypoxia, infection, inflammation, and certain adverse outcomes.

But meconium passage can also occur without fetal acidemia or a serious oxygen problem.

A major 2023 review of meconium-stained amniotic fluid notes that most fetuses with meconium-stained fluid do not have fetal acidemia.

For a potential birth injury case, the presence of meconium therefore needs to be evaluated with other evidence, including:

  • Fetal heart rate tracings
  • Maternal condition
  • Gestational age
  • Labor progression
  • Signs of infection
  • Umbilical cord blood gases
  • Apgar scores
  • Newborn resuscitation
  • Respiratory condition after birth

Meconium alone does not establish negligence or prove that the fetus was experiencing oxygen deprivation.

What Is Meconium Aspiration Syndrome?

Meconium aspiration syndrome, commonly called MAS, is a respiratory disorder occurring when a newborn exposed to meconium-stained fluid develops lung injury and breathing problems related to meconium aspiration.

Meconium can affect the lungs through several mechanisms.

It may:

  • Physically obstruct airways
  • Interfere with normal lung inflation
  • Trigger chemical inflammation in the lungs
  • Interfere with surfactant
  • Contribute to air trapping
  • Increase the risk of air leaks
  • Contribute to pulmonary hypertension

MAS can range from relatively mild respiratory distress to severe hypoxemic respiratory failure.

Does Every Baby Born Through Meconium Develop MAS?

No.

Only a minority of newborns exposed to meconium-stained amniotic fluid develop meconium aspiration syndrome.

Current medical references estimate that meconium passage occurs in a substantial minority of term and post-term births, while only a smaller percentage of exposed newborns go on to develop MAS.

That distinction matters.

The following are not interchangeable:

  • Meconium-stained amniotic fluid
  • Meconium present around the newborn
  • Meconium below the vocal cords
  • Meconium aspiration syndrome

A baby must be evaluated based on the actual respiratory findings and medical evidence.

What Are the Signs of Meconium Aspiration Syndrome?

A newborn with MAS may show respiratory distress shortly after birth.

Potential findings can include:

  • Rapid breathing
  • Grunting
  • Nasal flaring
  • Chest retractions
  • Low oxygen levels
  • Cyanosis or bluish coloration
  • Abnormal breath sounds
  • Difficulty maintaining oxygenation
  • Need for supplemental oxygen
  • Need for CPAP
  • Need for mechanical ventilation

The baby may also have visible meconium staining of the skin, nails, or umbilical cord, but staining alone does not diagnose MAS.

How Is MAS Diagnosed?

Doctors generally consider MAS when a newborn:

  1. Was delivered through meconium-containing amniotic fluid, and
  2. Develops respiratory distress that cannot be better explained by another condition.

Evaluation may include:

  • Physical examination
  • Pulse oximetry
  • Blood gases
  • Chest X-ray
  • Blood cultures or other infection testing
  • Echocardiography if PPHN is suspected

Other causes of neonatal respiratory distress can include:

  • Pneumonia
  • Sepsis
  • Transient tachypnea
  • Respiratory distress syndrome
  • Pneumothorax
  • Congenital heart disease
  • Other pulmonary disorders

A careful diagnosis therefore requires more than simply identifying meconium at delivery.

Do Doctors Still Suction Babies Born Through Meconium?

This is one area where older birth-injury information is frequently out of date.

Routine suctioning solely because meconium is present is no longer recommended.

The current 2025 American Heart Association and American Academy of Pediatrics Neonatal Resuscitation Guidelines state that routine:

  • Oral suctioning
  • Nasal suctioning
  • Oropharyngeal suctioning
  • Endotracheal suctioning

is not recommended, regardless of whether the amniotic fluid is clear or meconium-stained.

This applies even to babies who are not vigorous at birth.

Why Did the Guidance Change?

Older practice often involved aggressive suctioning because clinicians hoped to remove meconium before it reached the lungs.

Research did not show that routine suctioning improved outcomes.

It also created another concern:

Suctioning can delay effective ventilation.

The 2025 AHA/AAP guideline emphasizes that effective ventilation is the priority for newborns who need resuscitation.

Unnecessary suctioning can also cause problems such as:

  • Bradycardia
  • Apnea
  • Oxygen desaturation
  • Airway injury

The emphasis therefore shifted from routinely attempting to remove meconium to providing the respiratory support the newborn actually needs.

When Is Suctioning Appropriate?

The current guideline does not say that suctioning is never appropriate.

Suctioning can be considered when the baby’s airway appears obstructed.

For example:

  • The baby needs ventilation and visible material appears to obstruct the airway.
  • Ventilation remains ineffective despite corrective measures.
  • There is evidence of tracheal obstruction interfering with ventilation.

In those circumstances, suctioning the mouth and nose may help clear the airway.

Endotracheal intubation and tracheal suctioning can also be beneficial when there is evidence of an actual tracheal obstruction during ventilation.

The key distinction is:

Current practice treats airway obstruction—not the mere presence of meconium.

What About a Nonvigorous Baby With Meconium?

A nonvigorous newborn may have:

  • Poor respiratory effort
  • Apnea
  • Gasping
  • Low heart rate
  • Poor muscle tone

The outdated approach was to routinely intubate and suction these babies before moving on to other resuscitation steps.

That is no longer recommended.

The current AHA/AAP guidance prioritizes ventilation when the newborn needs respiratory assistance.

For a potential legal investigation, the relevant questions can include:

  • Was the newborn assessed promptly?
  • Was assisted ventilation indicated?
  • Was it started promptly?
  • Was suctioning performed unnecessarily?
  • Did suctioning delay ventilation?
  • Was ventilation ineffective because the airway actually was obstructed?
  • If obstruction was suspected, was it appropriately addressed?

How Quickly Should Ventilation Start?

The 2025 AHA/AAP Neonatal Resuscitation Guidelines state that ventilation should be provided within 60 seconds after birth for newborns who:

  • Are gasping,
  • Are apneic, or
  • Remain bradycardic with a heart rate under 100 beats per minute despite appropriate initial steps.

The guideline identifies effective lung ventilation as the central priority in neonatal resuscitation.

An increase in the baby’s heart rate is an important sign that ventilation is effective.

That does not mean every baby born through meconium needs ventilation.

Babies who are breathing well and transitioning normally generally do not need suctioning or assisted ventilation simply because meconium was present.

Who Should Be Present at a Delivery With Meconium-Stained Fluid?

Preparation is another important part of the current framework.

The 2025 AHA/AAP guideline recommends that every birth have at least one person present whose sole responsibility is care of the newborn and who can perform initial resuscitation steps and provide ventilation if required.

Before birth, the team should also:

  • Assess known perinatal risk factors
  • Determine the resuscitation team needed
  • Confirm that necessary equipment is available and functional
  • Conduct a prebirth team briefing for high-risk deliveries

ACOG specifically states that meconium-stained amniotic fluid requires notification and availability of an appropriately credentialed team with full newborn-resuscitation skills, including the ability to intubate.

A birth injury investigation involving MAS may therefore examine not merely what happened after birth but also how the delivery team prepared before the baby emerged.

When Might an MAS Case Raise Questions About Medical Negligence?

MAS itself does not establish malpractice.

Potential issues can nevertheless include the following.

Failure to Have an Appropriate Resuscitation Team Available

When meconium is identified during labor, ACOG recommends notifying and having available an appropriately credentialed resuscitation team.

A possible case may examine:

  • When meconium was first documented
  • Whether the neonatal team was notified
  • Who was present at delivery
  • Whether team members had appropriate resuscitation skills
  • Whether necessary equipment was immediately available
  • Whether delay occurred while staff or equipment were summoned

The presence of meconium does not guarantee that extensive resuscitation will be required.

The purpose of preparation is to be able to respond promptly if it is.

Delayed Ventilation

For newborns who are apneic, gasping, or persistently bradycardic, ventilation is the key resuscitative intervention.

A potential claim may focus on:

  • Time of birth
  • Initial heart rate
  • Initial respiratory effort
  • When stimulation occurred
  • When assisted ventilation began
  • Whether chest movement occurred
  • Heart-rate response to ventilation
  • Whether corrective ventilation steps were performed

A delay is not evaluated from the clock alone. Experts must examine what was happening clinically and whether care was reasonable under the circumstances.

Unnecessary Suctioning That Delayed Ventilation

Because current guidelines discourage routine suctioning, an investigation may ask whether prolonged attempts to suction meconium delayed a treatment the newborn actually needed.

Relevant records may include:

  • Resuscitation flow sheet
  • Intubation notes
  • Suction attempts
  • Heart-rate measurements
  • Oxygen saturation
  • Ventilation start time
  • Apgar components

Again, suctioning itself is not malpractice.

It may be appropriate if meconium or another substance is genuinely obstructing the airway.

Failure to Address an Obstructed Airway

The opposite problem can also occur.

If ventilation is ineffective because meconium is physically obstructing the airway, current guidance permits airway suctioning and, when necessary, endotracheal suction.

A complete review therefore must avoid simplistic claims such as:

  • “Suctioning is always wrong,” or
  • “Every meconium baby should be suctioned.”

Neither is correct.

Failure to Recognize Worsening Respiratory Distress

Some babies initially require relatively limited support but then develop more significant respiratory problems.

An investigation may examine:

  • Respiratory rate
  • Oxygen saturation
  • Work of breathing
  • Blood gases
  • Chest X-rays
  • Oxygen requirements
  • CPAP use
  • Mechanical ventilation
  • Air-leak complications

Delay in NICU Escalation or Transfer

A community hospital may be able to stabilize a newborn but not provide every form of advanced neonatal support.

When MAS becomes severe, the treatment team may need to consult a higher-level NICU or arrange transfer.

Potential issues include:

  • When severity was recognized
  • When neonatology was contacted
  • When transfer was requested
  • Whether appropriate respiratory support was maintained while awaiting transfer
  • Time the transport team arrived
  • Care during transport

The need for transfer does not mean the original hospital was negligent. The question is whether escalation occurred appropriately based on the newborn’s condition.

What Is Persistent Pulmonary Hypertension of the Newborn?

Persistent pulmonary hypertension of the newborn, or PPHN, is an important complication of severe MAS.

Before birth, the baby’s pulmonary blood vessels naturally have high resistance because oxygen comes from the placenta rather than the lungs.

After birth, pulmonary vascular resistance normally falls as the lungs expand and begin oxygen exchange.

With PPHN, that transition does not occur normally.

Pulmonary vascular resistance remains abnormally high, which can cause blood to bypass the lungs and produce severe hypoxemia.

MAS is one recognized cause of PPHN.

How Is PPHN Diagnosed?

A baby with PPHN may have:

  • Severe low oxygen levels
  • Cyanosis
  • Labile oxygen saturation
  • Respiratory distress
  • Poor response to ordinary oxygen treatment

Echocardiography is important because it can confirm pulmonary hypertension, assess heart function, evaluate blood-flow patterns, and help exclude certain congenital heart diseases.

Potentially important records therefore include the echocardiogram itself and the pediatric cardiology interpretation.

How Is Severe MAS Treated?

Treatment depends on severity.

Potential therapies can include:

  • Supplemental oxygen
  • CPAP
  • Mechanical ventilation
  • High-frequency ventilation
  • Surfactant in selected babies
  • Treatment for suspected infection while cultures are evaluated
  • Treatment of PPHN
  • Inhaled nitric oxide
  • Cardiovascular support
  • ECMO in the most severe refractory cases

No individual therapy is automatically required in every MAS case.

Treatment must be individualized to the newborn’s respiratory and cardiovascular condition.

Surfactant

Meconium can interfere with normal pulmonary surfactant.

Current medical references state that surfactant may be considered for mechanically ventilated newborns with significant oxygen requirements.

Evidence suggests surfactant can reduce the need for ECMO in severe MAS, although it has not been shown to reduce overall mortality.

Inhaled Nitric Oxide

When severe MAS is complicated by PPHN, inhaled nitric oxide may be used to relax pulmonary blood vessels and improve pulmonary blood flow and oxygenation.

Not every baby with MAS needs nitric oxide.

Its use depends on the severity and mechanism of hypoxemia.

ECMO

Extracorporeal membrane oxygenation, or ECMO, temporarily provides heart and lung support when severe respiratory failure does not respond adequately to conventional treatment.

It is reserved for selected critically ill infants.

Not every NICU offers neonatal ECMO, making timely consultation and transport potentially important when a baby reaches that level of illness.

Can MAS Cause Brain Injury?

It can, but MAS does not automatically cause neurological injury.

A severe episode involving prolonged hypoxemia, cardiovascular instability, or another associated perinatal problem can potentially affect the brain.

Some infants requiring advanced neonatal resuscitation may also have evidence of hypoxic-ischemic encephalopathy (HIE).

The 2025 AHA/AAP neonatal guideline recommends that infants at least 36 weeks’ gestation who required advanced resuscitation be evaluated for HIE to determine whether they meet criteria for therapeutic hypothermia.

For a child with both MAS and neurological injury, experts may need to distinguish between:

  • Lung injury from meconium
  • PPHN
  • An intrapartum hypoxic event
  • Infection
  • HIE
  • Other causes of encephalopathy

The diagnosis of MAS alone does not establish why neurological injury occurred.

What Records Matter in a Meconium Aspiration Case?

A complete investigation often spans labor, resuscitation, NICU treatment, transport, and follow-up care.

Prenatal Records

Request:

  • Prenatal chart
  • Maternal-fetal medicine records
  • Gestational-age documentation
  • Pregnancy complications
  • Ultrasound findings
  • Fetal testing
  • Maternal medical conditions
  • Infection-related records

Labor and Delivery Records

Potentially important records include:

  • Complete labor chart
  • Nursing notes
  • Obstetric notes
  • Electronic fetal monitoring strips
  • Labor flowsheets
  • Oxytocin records
  • Other medication records
  • Time membranes ruptured
  • Description of amniotic fluid
  • Time meconium was first noted
  • Description of meconium when documented
  • Maternal temperature
  • Infection evaluations
  • Delivery note

Fetal Monitoring Records

Ask specifically for the complete fetal heart rate tracing, not merely a written summary.

An expert may evaluate:

  • Baseline heart rate
  • Variability
  • Accelerations
  • Decelerations
  • Contraction patterns
  • Changes over time
  • Response to interventions

Meconium plus an abnormal tracing may raise different clinical questions than meconium with a reassuring tracing.

Delivery-Room Resuscitation Records

These can be central.

Request:

  • Neonatal resuscitation sheet
  • Time of birth
  • Initial respiratory effort
  • Initial heart rate
  • Apgar scores and component scores
  • Stimulation
  • Suction attempts
  • Ventilation start time
  • Mask ventilation documentation
  • Oxygen concentration
  • Pulse-oximetry results
  • Intubation attempts
  • Endotracheal suctioning
  • Chest compressions, if required
  • Epinephrine, if used

Exact timestamps can become particularly important.

Umbilical Cord and Early Blood Gases

Request:

  • Umbilical arterial blood gas
  • Umbilical venous blood gas
  • Early arterial blood gases
  • Venous or capillary blood gases

These results can help experts evaluate oxygenation, ventilation, and acid-base status.

A blood gas result must be interpreted with the rest of the clinical record.

Chest Imaging

Request the actual:

  • Chest X-rays
  • Other chest imaging, if obtained

as well as the radiology reports.

Imaging may help document findings associated with MAS or complications such as an air leak.

Respiratory Records

Save:

  • Oxygen requirements
  • CPAP settings
  • Ventilator settings
  • High-frequency ventilation data
  • Respiratory therapy notes
  • Surfactant administration
  • Oxygen saturation records

PPHN Records

If pulmonary hypertension developed, request:

  • Echocardiograms
  • Pediatric cardiology consultation
  • Oxygenation data
  • Inhaled nitric oxide orders
  • Nitric oxide dosing
  • Blood-pressure support
  • Vasoactive medication records

ECMO Records

For babies requiring ECMO, preserve:

  • ECMO consultation
  • Transfer documentation
  • Cannulation records
  • ECMO flowsheets
  • Cardiac and pulmonary imaging
  • Complication records
  • Decannulation records

Infection Evaluation

MAS and neonatal pneumonia can sometimes have overlapping findings.

Potential records include:

  • Blood cultures
  • CBC
  • Inflammatory markers
  • Placental pathology
  • Antibiotic orders
  • Maternal infection records

Transfer Records

If the baby was transferred:

  • Referral calls
  • Accepting-physician documentation
  • Transport-team notes
  • Time transfer was requested
  • Time the transport team arrived
  • Respiratory support during transfer
  • Arrival time at receiving NICU

Long-Term Records

If the child has persistent complications, save:

  • Pediatric pulmonology
  • Cardiology
  • Neurology
  • Audiology
  • Developmental evaluations
  • PT
  • OT
  • Speech therapy
  • Early-intervention records
  • School records where relevant

Why the Resuscitation Record Is So Important

Parents may understandably focus on the obstetric chart.

In an MAS case, however, the newborn resuscitation record can be just as important.

Current resuscitation guidance focuses heavily on:

  • Initial breathing
  • Heart rate
  • Effective ventilation
  • Response to ventilation
  • Airway obstruction
  • Escalation to advanced resuscitation

The resuscitation sheet may show events minute by minute.

That can help experts evaluate whether the team followed an appropriate sequence and whether a disputed delay actually occurred.

What Kentucky Parents Can Do After a Serious MAS Diagnosis

1. Focus on the Baby’s Current Medical Care

If your newborn is struggling to breathe, medical treatment comes first.

Ask the neonatal team to explain:

  • How severe the respiratory disease is
  • Whether MAS is the confirmed diagnosis
  • Whether another lung condition or infection is possible
  • Whether PPHN is present
  • What respiratory support is being used
  • Whether transfer is needed

2. Ask What Happened During Resuscitation

Useful questions can include:

  • Was my baby breathing at birth?
  • What was the initial heart rate?
  • Was assisted ventilation needed?
  • When was ventilation started?
  • Was the airway obstructed?
  • Was suctioning performed?
  • Was the baby intubated?
  • Were chest compressions needed?

3. Request Complete Records

Request records from:

  • Prenatal providers
  • Obstetric practice
  • Delivery hospital
  • Newborn nursery
  • NICU
  • Transport service
  • Receiving hospital
  • Pediatric specialists

4. Preserve the Complete Fetal Monitoring Record

Ask for the actual electronic tracing.

Do not assume the written labor notes contain all of the information shown on the monitor.

5. Build a Timeline

Write down:

  • When meconium was first mentioned
  • What staff said about it
  • Time of delivery
  • Whether the baby cried
  • When the baby was moved for resuscitation
  • When NICU staff arrived
  • Whether transfer was discussed
  • When transfer occurred

6. Preserve Imaging and Echocardiography

If your baby had chest imaging or an echocardiogram, preserve the actual study when possible, not just the report.

7. Keep Long-Term Follow-Up Records

Save documentation concerning any ongoing:

  • Respiratory problems
  • Pulmonary hypertension
  • Developmental concerns
  • Hearing problems
  • Neurological diagnoses
  • Therapy needs

8. Have Kentucky Legal Deadlines Evaluated Promptly

Kentucky’s deadline analysis depends on the particular claim and defendant.

Families should not assume that every claim involving a newborn automatically remains open until adulthood.

Advanced Neonatal Care in Kentucky

A baby with severe MAS, PPHN, or respiratory failure may need a higher level of neonatal care.

Whether transfer is necessary is a medical decision for the treating healthcare professionals.

Golisano Children’s at UK — Lexington

The former Kentucky Children’s Hospital is now Golisano Children’s at UK.

UK HealthCare operates a Level IV NICU in Lexington for critically ill newborns.

Level IV is the highest NICU level and provides access to advanced neonatal medical and surgical care.

Kentucky Kids Crew

UK HealthCare’s Kentucky Kids Crew provides specialized hospital-to-hospital neonatal and pediatric critical-care transportation.

The team is available 24 hours a day, seven days a week and uses specialized ground and air transportation.

Norton Children’s Hospital — Louisville

Norton Children’s Hospital operates a Level IV NICU in downtown Louisville.

Newborns from other hospitals throughout the region may be transferred there for advanced neonatal care.

Norton Children’s also publicly identifies the hospital as an ECMO Center of Excellence, an advanced resource relevant to selected infants with severe respiratory or cardiovascular failure.

“Just for Kids” Transport Team

The Norton Children’s “Just for Kids” Transport Team provides neonatal and pediatric transportation between hospitals.

The service is available 24/7 by specialized ground ambulance and helicopter.

These facilities are listed as Kentucky treatment resources only. Their inclusion does not suggest negligence by either health system or any provider.

Kentucky Law and Meconium Aspiration Birth Injury Claims

Kentucky’s General Medical Malpractice Deadline

The current version of KRS 413.140, effective July 15, 2026, generally requires negligence or malpractice actions against covered physicians, surgeons, dentists, and hospitals to be commenced within one year after the cause of action accrues.

For covered medical-malpractice actions, the statute states that the claim accrues when the injury is:

  • First discovered, or
  • In the exercise of reasonable care should have been discovered.

The statute also contains a five-year outside provision measured from the alleged negligent act or omission.

The correct limitations analysis depends on the actual claim and defendants.

Does Kentucky Toll the Deadline for an Injured Newborn?

KRS 413.170 provides tolling for certain causes of action when the person entitled to bring the claim was an infant—meaning a minor—when the cause of action accrued.

Because KRS 413.140 is within the range of statutes referenced by KRS 413.170, minority can materially affect a child’s own malpractice claim.

But it is too broad to say that every claim connected with a baby’s injury automatically remains open until adulthood.

Different rules may apply to:

  • A parent’s independent claim
  • A wrongful-death claim
  • An estate’s claim
  • A state institution
  • A state employee
  • Another governmental defendant
  • A claim governed by a separate statutory procedure

Each claimant and defendant should be analyzed separately.

Special Rules Can Apply to UK HealthCare and Other State Institutions

This issue can matter when treatment involves the University of Kentucky, because Kentucky treats state institutions of higher education as state agencies for purposes of the Board of Claims statutes.

Under KRS 49.070, the Kentucky Board of Claims has primary and exclusive jurisdiction over certain negligence claims involving the Commonwealth, its agencies, and employees acting within the scope of state employment.

KRS 49.120 contains different filing rules.

For medical malpractice claims before the Board:

  • Claims generally must be filed within one year after accrual.
  • Medical malpractice uses a discovery rule.
  • The statute contains a three-year outside period.
  • A guardian, next friend, or other qualified representative must bring a minor’s claim within the applicable Board deadline.

Importantly, KRS 49.120 states that its disability provision applies notwithstanding KRS 413.170.

Families therefore should not assume ordinary infancy tolling governs a possible claim involving a state institution.

Whether a particular UK HealthCare provider, employee, contractor, entity, or claim falls within the Board of Claims process requires individualized legal analysis.

Kentucky’s Certificate-of-Merit Requirement

Kentucky also imposes an important filing requirement for many medical malpractice lawsuits.

Under KRS 411.167, a claimant commencing a covered medical malpractice action generally must file a certificate of merit with the complaint.

The certificate ordinarily states that:

  • The claimant reviewed the facts
  • The claimant or attorney consulted at least one qualified expert
  • The expert is knowledgeable about the relevant issues
  • The consultation supports a reasonable basis for filing the action

The statute contains exceptions and alternative procedures for specified circumstances.

It also addresses situations where requested medical records have not yet been produced.

That is another reason to request delivery, fetal-monitoring, imaging, resuscitation, and NICU records early.

Does Kentucky Require a Medical Review Panel?

No.

Kentucky previously enacted a mandatory medical review panel system.

The Kentucky Supreme Court held the law unconstitutional in Commonwealth ex rel. Meier v. Claycomb.

The old medical review panel requirement therefore does not apply.

It should not be confused with Kentucky’s separate certificate-of-merit requirement.

Do MAS Birth Injury Cases Require Medical Experts?

Usually.

Potential medical issues can include:

  • Obstetric care
  • Fetal heart rate monitoring
  • Newborn resuscitation
  • Airway management
  • Mechanical ventilation
  • Neonatology
  • PPHN
  • Pediatric cardiology
  • Pulmonary injury
  • HIE
  • Long-term causation

Relevant experts may include:

  • Obstetricians
  • Maternal-fetal medicine physicians
  • Labor and delivery nurses
  • Neonatologists
  • Pediatric pulmonologists
  • Pediatric cardiologists
  • Pediatric neurologists
  • Respiratory-care experts

Kentucky’s KRE 702, as amended effective July 1, 2024, governs expert testimony.

Expert witnesses generally must explain not merely that the baby developed MAS but whether a specific departure from appropriate care caused or materially worsened an injury.

Do AHA, AAP, or ACOG Guidelines Automatically Prove Malpractice?

No.

Professional guidelines provide important medical context, but they do not automatically determine the legal standard of care in every individual case.

Experts must consider:

  • Clinical circumstances
  • Information available at the time
  • Gestational age
  • Fetal condition
  • Newborn condition
  • Hospital resources
  • Team preparation
  • Response to treatment
  • Other potential causes of injury

For example, the fact that suctioning occurred does not automatically prove negligence because suctioning can be appropriate for an actual airway obstruction.

Likewise, failure to suction a baby simply because meconium was present is not automatically negligent under current resuscitation guidance.

Who Could Be Responsible for Preventable MAS-Related Harm?

Potential responsibility depends on the evidence.

An investigation may examine care provided by:

  • Obstetricians
  • Family physicians providing obstetric care
  • Midwives
  • Labor and delivery nurses
  • Newborn nursery staff
  • Neonatologists
  • Respiratory therapists
  • Pediatric providers
  • Hospitals or health systems

Potential institutional issues can include:

  • Resuscitation-team readiness
  • Equipment availability
  • Staffing
  • Communication
  • Escalation procedures
  • NICU capability
  • Transport procedures
  • Hospital resuscitation training

The involvement of a provider or hospital does not itself establish liability.

Can the Hospital Be Responsible or Only the Doctor?

Potentially either, both, or neither.

Questions can include:

  • Who was responsible for the newborn at delivery?
  • Was the appropriate resuscitation team present?
  • Who made airway-management decisions?
  • Who was responsible for NICU escalation?
  • Did hospital systems contribute to any delay?
  • Who employed the providers?
  • Was a provider an employee, contractor, agent, or state employee?

Those relationships can affect both liability and the proper legal forum.

What Long-Term Problems Can Follow Severe MAS?

Many infants with MAS recover without major long-term disability.

Severe cases can involve substantial medical complications.

Potential concerns may include:

  • Severe respiratory failure
  • PPHN
  • Pneumothorax or other air leaks
  • Need for prolonged ventilation
  • HIE or another neurological injury when severe perinatal hypoxia also occurred
  • Developmental concerns
  • Ongoing respiratory symptoms

Whether a later condition was actually caused by MAS requires medical evidence.

Potential damages in a supported Kentucky claim may involve:

  • NICU treatment
  • Respiratory treatment
  • Specialist care
  • Therapy
  • Medical equipment
  • Developmental services
  • Future medical care
  • Lost earning capacity
  • Other compensable harms permitted by Kentucky law

There is no responsible way to determine the value of a case merely from the diagnosis “MAS.”

What if the Newborn Dies?

Kentucky wrongful-death claims are governed in part by KRS 411.130.

A wrongful-death action is prosecuted by the deceased person’s personal representative.

Wrongful-death claims have deadline and procedural rules different from a living child’s personal malpractice claim.

Families should therefore not rely on the ordinary minority-tolling discussion when evaluating a fatal MAS case.

Frequently Asked Questions About Meconium Aspiration in Kentucky

What is meconium aspiration syndrome?

MAS is a respiratory disorder occurring when a newborn exposed to meconium-stained amniotic fluid develops lung injury and respiratory distress associated with meconium aspiration.

Does meconium in the amniotic fluid mean the baby was deprived of oxygen?

No.

Meconium can be associated with fetal stress or hypoxia, but most fetuses with meconium-stained fluid do not have fetal acidemia.

The fetal monitoring, cord gases, newborn condition, and other evidence must be considered.

Does every baby exposed to meconium develop MAS?

No.

Most do not.

Meconium-stained fluid is much more common than meconium aspiration syndrome.

Do doctors still routinely suction a baby when meconium is present?

No.

The 2025 AHA/AAP Neonatal Resuscitation Guidelines state that routine oral, nasal, or endotracheal suctioning is not recommended solely because meconium is present.

What if the baby is not breathing well?

Ventilation is the priority when a newborn is apneic, gasping, or persistently bradycardic despite initial steps.

The current guideline recommends providing ventilation within the first 60 seconds for newborns who meet those criteria.

Can doctors ever suction meconium from the airway?

Yes.

Suctioning can be appropriate when there is evidence that material is obstructing the airway.

Endotracheal suctioning may be beneficial when a tracheal obstruction is interfering with effective ventilation.

Does suctioning a meconium baby automatically mean the doctor used outdated care?

No.

The reason for suctioning matters.

Routine suctioning solely because meconium was present is no longer recommended, but suctioning for an actual airway obstruction can be appropriate.

Does failure to suction automatically mean malpractice?

No.

Current guidance specifically discourages routine suctioning.

Should a specialized team be present for a meconium delivery?

ACOG states that meconium-stained amniotic fluid requires notification and availability of an appropriately credentialed team with full newborn-resuscitation skills, including intubation capability.

Can MAS cause PPHN?

Yes.

Meconium aspiration syndrome is a recognized cause of persistent pulmonary hypertension of the newborn.

How is PPHN treated?

Treatment depends on severity and underlying lung disease.

Potential treatments can include oxygen, ventilation, cardiovascular support, pulmonary vasodilators such as inhaled nitric oxide, and ECMO in selected severe cases.

Does every baby with MAS need a NICU?

No.

The level of care depends on respiratory severity and the baby’s overall condition.

Babies requiring substantial respiratory support, monitoring, or treatment for PPHN may require neonatal intensive care.

Where is Level IV NICU care available in Kentucky?

Current Kentucky resources include Golisano Children’s at UK in Lexington and Norton Children’s Hospital in Louisville, both of which operate Level IV NICUs.

What records are most important in a possible MAS malpractice case?

Frequently important records include:

  • Complete fetal heart rate tracings
  • Labor and delivery notes
  • Documentation of meconium
  • Neonatal resuscitation sheet
  • Apgar scores
  • Cord gases
  • Early blood gases
  • Chest X-rays
  • Ventilator records
  • PPHN records
  • Echocardiograms
  • Nitric oxide records
  • Transfer documentation
  • NICU records

Is amnioinfusion required whenever meconium is present?

No universal rule requires amnioinfusion simply because meconium is present.

Research has produced differing findings. A Cochrane review found substantial benefit primarily in settings with limited peripartum surveillance, while a more recent meta-analysis reported reduced MAS and other adverse outcomes with prophylactic amnioinfusion.

Whether amnioinfusion was medically appropriate in a particular labor requires case-specific obstetric analysis.

Its use or non-use alone should not be treated as proof of malpractice.

What is Kentucky’s deadline for an MAS malpractice case?

KRS 413.140 generally imposes a one-year period for covered medical malpractice claims against private physicians and hospitals and contains a discovery rule and five-year outside provision.

KRS 413.170 can affect certain claims belonging to minors.

Different rules can apply to state entities, parents’ own claims, wrongful death, and other proceedings.

There is no single universally safe deadline for every MAS case.

Does Kentucky require a medical review panel?

No.

Kentucky’s former mandatory medical review panel law was held unconstitutional.

Does Kentucky require a certificate of merit?

For many covered medical malpractice actions, yes.

KRS 411.167 generally requires a certificate of merit with the complaint, subject to the statute’s exceptions and alternative procedures.

Do I need medical experts?

Usually.

MAS cases can require experts in obstetrics, neonatal resuscitation, neonatology, pulmonology, cardiology, or neurology to distinguish an unavoidable complication from preventable injury.

How Morrin Law Office Evaluates a Meconium Aspiration Case

A serious MAS investigation should begin with the actual clinical record rather than an assumption that meconium automatically means something went wrong.

Our review may involve:

  1. Obtaining the complete prenatal and labor record.
  2. Preserving the complete fetal heart rate tracing.
  3. Determining when meconium was first documented.
  4. Reviewing who was present for newborn resuscitation.
  5. Building a detailed timeline of the baby’s first minutes after birth.
  6. Reviewing ventilation, suctioning, intubation, and other resuscitation steps.
  7. Obtaining cord gases and early blood gases.
  8. Preserving chest X-rays, echocardiograms, and other imaging.
  9. Reviewing respiratory-support and ventilator records.
  10. Evaluating whether PPHN developed and how it was treated.
  11. Reviewing nitric oxide, surfactant, ECMO, and other advanced therapies when applicable.
  12. Reviewing NICU escalation and inter-hospital transfer timing.
  13. Considering infection, HIE, congenital conditions, and other possible explanations for the baby’s condition.
  14. Consulting qualified medical experts when appropriate.
  15. Evaluating whether a departure from appropriate care actually caused or worsened an injury.
  16. Identifying potentially responsible providers and healthcare entities.
  17. Determining whether ordinary Kentucky court procedures or Board of Claims rules may apply.
  18. Evaluating Kentucky’s certificate-of-merit requirement and filing deadlines.
  19. Documenting any long-term respiratory, neurological, developmental, or other effects.

Some MAS cases involve complications that occurred despite appropriate medical care.

Others may support a conclusion that delayed resuscitation, airway management, escalation, or other preventable care contributed to injury.

The purpose of the investigation is to determine what the records and qualified medical experts actually support.

Meconium-stained fluid and MAS can occur even when appropriate medical care is provided. Current neonatal-resuscitation guidance does not recommend routine suctioning merely because meconium is present.

Medical guidance, laws, filing requirements, and deadlines can change. If a newborn is currently experiencing respiratory distress, rely on qualified healthcare professionals for immediate medical decisions. If you have questions about possible legal rights or filing deadlines, consider obtaining individualized legal advice promptly.
