Phenobarbital is the medicine most often used first to treat seizures in newborns, including seizures caused by HIE. Seizures are common after HIE because the injured brain can fire abnormally, and controlling them helps protect the brain and lets the team read the baby’s condition. It is usually given in the NICU with EEG monitoring, and many babies are weaned off it over time.

Introduction: why this question matters for your family

Families often arrive at this question during or soon after the NICU stay, when a new term, test, or piece of the medical picture raises questions. This article is written for families whose newborn is being treated for seizures after hie and explains what the question really means, what to expect, and the next steps other families have found most useful.

What this really points to

Behind the question are patterns that a neonatology and pediatric neurology team can recognize quickly. The specific thing parents typically describe is newborn seizures on EEG or exam that the team treats with medication. One observation rarely answers the question on its own; a clear picture comes together from what parents notice, the history, and a focused evaluation [1].

The most useful next step is usually an evaluation by a neonatology and pediatric neurology team, often with EEG or aEEG monitoring to detect seizures and guide medication [3].

Example 1: A cooled newborn has seizures on EEG, so the team starts phenobarbital and watches the tracing for a response.

Why early action makes a real difference

Acting early matters because intervention windows in infancy and early childhood are real. The developing brain is most adaptive in the first two to three years of life [3].

Every U.S. state runs an Early Intervention (Part C) program offering free evaluations and therapy for eligible children under 3 [5].

What usually lies behind it

The most relevant contributing factor here is abnormal electrical activity in a brain stressed by oxygen shortage around birth. This is the underlying mechanism behind what parents notice: newborn seizures on EEG or exam that the team treats with medication [2].

The cause may have been present before birth, may have happened during labor or delivery, may have occurred during the NICU stay, or may have only become apparent as your child grew.

If you also notice this, here is what to consider next
Asymmetric movement
Consider: General Movements Assessment (GMA) and HINE
Tone abnormalities
Consider: Pediatric neurology referral
Multiple delayed milestones
Consider: Developmental pediatrics evaluation
NICU history with delays
Consider: Comprehensive NICU follow-up clinic visit
Difficulty with feeding or sleep
Consider: Multi-disciplinary developmental team review
Strong family instinct that something is off
Consider: Trust it – request a referral or call EI directly

How a real evaluation works

A typical evaluation here combines a careful history, a focused examination, and the tests that fit the concern. Where useful, the team adds EEG or aEEG monitoring to detect seizures and guide medication [4].

Therapy referrals frequently happen at the same evaluation, before any formal diagnosis is finalized.

Mistakes families often make

The most common mistakes we see: waiting too long on a quiet ‘let us wait and see,’ comparing one child to another, skipping NICU follow-up visits, and not requesting the full medical record.

Trusting your own observation is one of the strongest tools you have [3].

Example 2: As a baby recovers, the neurology team gradually weans the phenobarbital while monitoring for any return of seizures.

Step-by-step: what parents can do next

If the patterns described above match what you are seeing, here is a practical sequence other families whose newborn is being treated for seizures after hie have found useful.

1
Gather and keep the key records and results (NICU discharge summary, imaging, and any lab values), and note any new concerns about your baby’s breathing, feeding, muscle tone, or development.
2
At your next visit, describe your concern in concrete terms and show one or two videos if you have them. Ask whether a referral to a neonatology and pediatric neurology team is appropriate now.
3
Call your state’s Early Intervention (Part C) line yourself [5]. You do not need a doctor referral to start.
4
Request the records that matter: NICU discharge summary, imaging reports, MRI or cranial ultrasound, and labor and delivery flow sheets.
5
If the evaluation suggests neurodevelopmental follow-up and, where needed, ongoing seizure care would help, begin it as soon as you can.
6
For major decisions, get a second opinion at a children’s hospital with subspecialty depth in your child’s area of concern. Bring all reports.
7
If a birth event may have played a role, schedule a free, no-pressure case review with CP Family Help.

When to get help quickly

If a baby has a seizure at home (rhythmic jerking, stiffening, staring with lip-smacking or eye deviation, or a pause in breathing), seek emergency care right away (call 911 or go to the ER).

What to bring to every follow-up visit

Bring three things: a short list of what has changed since last time, one or two phone videos, and a single specific question.
