One page summary: Neonatal meningitis

In two sentences

Neonatal meningitis is infection of the fluid and membranes around the brain and spinal cord in the first month of life. It is uncommon and it is serious. ¹

The single most important point on this page is that meningitis in a newborn can be present when the blood culture is negative. The only way to find it is a lumbar puncture, and skipping it means a baby can be treated for too short a time for the infection they actually have. ¹

The numbers, with their sources

• The organisms. Group B strep and E. coli are the leading causes of early newborn meningitis, with Listeria less common ²
• Why the spinal tap matters. Meningitis can be present with a negative blood culture, so a blood test alone cannot rule it out ¹
• Why treatment length differs. Meningitis needs a longer course of antibiotics than bloodstream infection alone, and the duration depends on the organism ¹
• The main complications. Hearing loss, hydrocephalus, seizures, and brain injury ³
• Required follow-up. A full hearing assessment after meningitis, because hearing loss is a recognized consequence and may not be detected by newborn screening alone ⁴
• National surveillance. CDC tracks invasive Group B strep disease, including meningitis, through Active Bacterial Core surveillance ⁵

What to do this week

1. Ask whether a lumbar puncture was done, and if not, why not and whether it will be.
2. Ask what the spinal fluid showed and what organism grew.
3. Ask how long the antibiotic course is and what determines that.
4. Ask whether head circumference is being tracked and whether the ventricles are being watched.
5. Book a full audiology assessment, and keep it.
6. Ask what the MRI showed.
7. Refer to early intervention.

Questions to take with you

Take these with you. Write the answers down in the moment, because you will not remember them later.

For the neonatologist

• Was a lumbar puncture done, and what did the spinal fluid show?
• What organism, and how long is the antibiotic course?
• Will the lumbar puncture be repeated?
• Are the ventricles enlarging?
• What did the MRI show?

For the audiologist

• What kind of hearing testing is being done?
• When should we retest, given that hearing loss after meningitis can be progressive?
• What should we watch for at home?

For the neurologist or neurosurgeon

• Is hydrocephalus developing, and what number are you watching?
• Is there a seizure risk, and what would a seizure look like?
• What follow-up do you want, and for how long?
