Miami Kernicterus Lawyer: Sean M. Cleary

What Kernicterus Is and How It Develops

Jaundice is one of the most frequently seen conditions in newborns, affecting more than 80% of newborns to some degree in their first days of life. In most cases, it resolves on its own or with minimal intervention. Kernicterus develops when bilirubin levels rise to a point where unconjugated bilirubin crosses the blood-brain barrier and begins damaging brain tissue, a progression that can move quickly and without obvious warning signs if bilirubin is not being monitored appropriately.

The American Academy of Pediatrics identifies kernicterus as one of the most preventable causes of severe neonatal brain injury precisely because the pathway from jaundice to brain damage requires bilirubin to reach dangerous levels over time. When healthcare providers screen newborns, identify those at high risk, and initiate treatment before bilirubin reaches those levels, kernicterus does not occur. When they do not, the neurological damage that results is permanent and irreversible.

Medical Failures That Can Lead to Kernicterus

Kernicterus does not develop without a gap in care, and birth injury claims involving kernicterus are focused on identifying exactly where that gap occurred. Medical records commonly reviewed in these cases include bilirubin measurements, bilirubin nomograms, feeding records, newborn examination notes, phototherapy records, and pediatric neurology assessments. The questions those records are used to answer include whether providers:

• Measured bilirubin levels in a timely and appropriate manner
• Properly identified the newborn as high risk for severe hyperbilirubinemia
• Initiated phototherapy when bilirubin levels indicated it was needed
• Performed an exchange transfusion when bilirubin reached dangerous levels despite phototherapy
• Provided appropriate discharge instructions and arranged adequate follow-up after early hospital discharge

The USA Kernicterus Registry found that many infants who developed kernicterus were readmitted within the first week of life with rapidly rising bilirubin levels that had not been recognized during or immediately after their initial hospital stay. Risk factors, including hemolytic disease, prematurity, dehydration, infection, and G6PD deficiency, were often present and documented but not acted upon appropriately.

Signs That Kernicterus May Have Occurred

Kernicterus progresses through stages, beginning with acute bilirubin encephalopathy before causing permanent damage. Signs that dangerous bilirubin levels may be affecting a newborn include:

• Extreme jaundice visible in the skin & eyes
• Lethargy or difficulty waking
• Poor feeding
• High-pitched crying
• Arching of the back and neck
• Seizures
• Fever

If your newborn was discharged from the hospital and then readmitted within the first week of life with any of these signs, the adequacy of bilirubin monitoring before discharge and the follow-up plan provided to your family are central questions in evaluating whether a standard of care violation occurred.

Long-Term Effects of Kernicterus on Children and Families

Once kernicterus causes brain damage, the neurological injuries it produces are irreversible. The American Academy of Pediatrics describes it as a permanent disabling neurological condition that can result in choreoathetoid cerebral palsy, sensorineural hearing loss, auditory neuropathy, upward gaze palsy, dental enamel dysplasia, and characteristic MRI abnormalities. Time alone won't improve these conditions; they require ongoing management, therapy, and support for life.

The outcomes data for untreated kernicterus reflect how serious the condition is. Mortality reaches at least 10%, and at least 70% of survivors experience permanent neurological disability. For families whose children survive with these disabilities, the financial and emotional demands of lifelong care are substantial. When those demands result from a failure to perform a standard bilirubin screening or initiate phototherapy on time, the law provides a clear path to accountability.

What You Can Recover in a Kernicterus Claim in Florida

Families pursuing a birth injury or medical malpractice claim in Florida related to kernicterus may be entitled to compensation for:

• Past and future medical expenses
• Neurological care and management of cerebral palsy
• Hearing evaluation and auditory support
• Physical, occupational, and speech therapy
• Special education and developmental support
• Assistive devices and home modifications
• Loss of the child's future earning capacity
• Pain and suffering
• Mental anguish
• Lost income of a parent who reduces work to provide care

In cases where kernicterus results in the death of a newborn, a wrongful death claim may allow the family to recover for funeral expenses, medical costs incurred prior to death, and loss of companionship.
