Most newborns become at least slightly jaundiced in the first days, as bilirubin builds up faster than an immature liver clears it. In the overwhelming majority it resolves without treatment or needs nothing more than light therapy.
Kernicterus is what happens when it is allowed to go too far. At high enough levels bilirubin crosses into the brain and damages it permanently. What makes these cases different from most birth injury claims is that nothing rare or unforeseeable is involved: the risk is known, the measurement is routine and the treatment is ordinary.
What kernicterus is
Bilirubin is produced when red blood cells break down. A newborn liver clears it slowly, so levels rise in the first days of life and then fall. Where they rise too high and stay there, bilirubin can cross into brain tissue and cause injury that does not heal.
The damage characteristically affects particular areas of the brain, which is why the resulting disability has a recognizable pattern:
- Athetoid, or dyskinetic, [cerebral palsy](/cerebral-palsy-lawyer/) — involuntary writhing movements and difficulty controlling posture
- Hearing loss, including auditory processing problems where hearing tests appear normal
- Problems with upward gaze and eye movement
- Dental enamel defects in the baby teeth
- Cognitive effects, though intelligence is often less affected than movement
The risk factors that should raise the alarm
These are known, taught and screened for, which is what makes a failure to act on them so difficult to justify:
- Blood type incompatibility between mother and baby, including ABO and Rh incompatibility, which causes faster red cell breakdown
- Prematurity, or birth near term but not at it
- Bruising or a cephalohematoma from delivery, which adds to the bilirubin load
- Feeding difficulty and weight loss, particularly where breastfeeding is not yet established
- G6PD deficiency, which runs in families and is often undiagnosed
- A sibling who needed treatment for jaundice
- Jaundice appearing in the first 24 hours, which is never treated as normal
Where the care goes wrong
Kernicterus claims almost always come down to one of a small number of failures:
- Bilirubin never measured, or judged by eye. Visual assessment of jaundice is unreliable, particularly in babies with darker skin, and a measurement is the standard.
- Measured and not acted on. Levels are interpreted against the baby’s age in hours and risk factors, not against a single universal number, and a level that is acceptable at 72 hours may be dangerous at 24.
- Discharged without follow-up. Early discharge is routine and safe only where a timely check is arranged; bilirubin often peaks after the family has gone home.
- Parental reports dismissed — a baby who is increasingly yellow, sleepy, feeding poorly or arching is a baby who needs re-measuring, not reassurance.
- Treatment delayed. Phototherapy is straightforward. Where levels are dangerously high, exchange transfusion is the escalation, and delay at that point is measured in hours.
- Underlying cause not investigated, such as unrecognized blood group incompatibility or haemolysis.
How these claims are proven
- The numbers and their timing: every bilirubin measurement, the baby’s age in hours at each, and how they track against the thresholds that applied.
- The risk factors documented at birth, and whether they changed what should have been done.
- The discharge decision and what follow-up was actually arranged.
- What the parents reported, and when, at each contact after discharge.
- When treatment began, relative to when it was indicated.
- Expert evidence on whether timely measurement and treatment would have prevented the injury — the causation question, and the one that decides the case.
Maryland requires a certificate from a qualifying expert before the claim proceeds, and it is filed with the state health care dispute office first, as with any medical malpractice claim.
What these claims have to cover
Kernicterus causes lifelong disability, so the claim is valued from a life care plan rather than from treatment to date: therapy, equipment, communication aids, hearing support, home adaptation, attendant care, educational support and lost earning capacity across a lifetime.
Maryland caps non-economic damages in malpractice cases and adjusts the cap annually. The care costs are not capped, which is why the plan is the center of the case.
How long families have
Malpractice claims generally run five years from the injury or three years from discovery, whichever comes first, and claims on behalf of a child follow their own rules, which can extend the time available.
Kernicterus is frequently identified long after the newborn period, when a child is diagnosed with athetoid cerebral palsy or hearing loss and someone looks back at the newborn records. That is a normal way for these claims to begin, and it is worth asking rather than assuming too much time has passed.
