Pediatric Neurocritical Care

Children Are a Distinct Blueprint Population

The outline explicitly includes pediatric patients. The relevant task is to recognize when age changes physiology, disease likelihood, equipment, dosing, or interpretation. Infants and children have different airway anatomy, blood-pressure ranges, blood volume, glucose reserves, and developmental baselines. A behavior or examination that is abnormal for an adolescent may not be interpretable the same way in a young infant.

Use an age-appropriate resuscitation framework and obtain pediatric critical care expertise early for severe illness. Record age, weight, premorbid development, immunization and infection history, trauma mechanism, and potential exposures. Confirm units and maximum doses when calculating medication or fluid therapy. A tenfold decimal error can be especially consequential when small volumes and concentrated drugs are used.

Airway, Ventilation, and Circulation

Children can deteriorate rapidly with airway obstruction, hypoventilation, or shock. Select appropriately sized airway devices and confirm placement and ventilation. Avoid assuming that a displayed oxygen saturation excludes hypercapnia or inadequate ventilation. Assess work of breathing, respiratory pattern, gases when indicated, and the ability to protect the airway.

Hypotension can be a late sign of pediatric shock. Capillary refill, skin temperature, pulse quality, mental status, urine output, lactate trends, and pressure together inform perfusion. Age-based limits differ from adult thresholds. In severe TBI, prevent hypoxemia and inadequate cerebral perfusion while treating hemorrhage or other shock causes. Do not apply permissive hypotension indiscriminately to a child with brain injury.

Pediatric Severe TBI

The Brain Trauma Foundation's pediatric third-edition guideline is separate from the adult guideline. It suggests treating intracranial hypertension above 20 mm Hg and maintaining CPP at least 40 mm Hg; a target range around 40–50 mm Hg is considered, with infants toward the lower end and adolescents toward the upper end. These are guideline-based starting points with limited evidence, not a claim that a single pressure guarantees safety in every child.

Hyperosmolar treatment requires weight-based protocols, electrolyte and renal monitoring, and response assessment. Avoid prophylactic severe hyperventilation and use emergency rescue ventilation only for an appropriate indication while definitive treatment is organized. Steroids do not treat traumatic cerebral edema. Decisions about ICP monitoring, surgery, seizure prophylaxis, nutrition, and sedation require pediatric application rather than simply copying an adult order set.

Seizures, Infection, and Inflammation

Age changes the differential for seizures and encephalopathy. Consider infection, metabolic and toxic causes, accidental or inflicted injury, vascular disease, and inflammatory conditions. Hypoglycemia must be recognized and treated promptly. A prolonged seizure requires rapid treatment using pediatric dosing and airway preparation; persistent impaired consciousness after motor activity stops can require EEG assessment for ongoing electrographic seizures.

Infants may have meningitis without classic neck stiffness, and immunocompromised children may have muted inflammatory findings. Start indicated empirical therapy without waiting for an unsafe or delayed LP. MRI and CSF studies are chosen for the syndrome and safety assessment. Pediatric ADEM and autoimmune encephalitis can cause substantial encephalopathy, movement abnormalities, autonomic dysfunction, or respiratory compromise and need coordinated immune and infectious evaluation.

Vascular Disease, Hydrocephalus, and Trauma

Pediatric stroke may involve arteriopathy, congenital or acquired cardiac disease, sickle cell disease, infection, dissection, or other mechanisms. The 2026 AHA/ASA AIS guideline includes pediatric interventional recommendations for selected patients; this does not make adult eligibility criteria universally applicable. Use pediatric stroke and neurointerventional expertise urgently rather than excluding treatment solely because the patient is a child.

Hydrocephalus and shunt malfunction can present with vomiting, irritability, headache, altered consciousness, or age-dependent examination changes. Compare with prior imaging and shunt history; normal-looking ventricular size does not always exclude malfunction. In suspected inflicted injury, prioritize resuscitation and objective assessment, involve the appropriate safeguarding team, and document findings without prematurely assigning a mechanism from one isolated sign.

Prognosis and Death Determination

Developmental recovery, premorbid function, family priorities, and the cause of injury matter in prognostic counseling. Do not use an adult cardiac-arrest biomarker cutoff or an adult score as a validated personal pediatric forecast. Distinguish uncertain neurologic prognosis from the separate legal and clinical determination of death.

The 2023 AAN/AAP/CNS/SCCM guideline specifies pediatric prerequisites, two independent examinations separated by at least 12 hours, and two apnea tests when they can be performed safely. It also has age- and injury-dependent observation requirements before evaluation. TCD is not an accepted pediatric ancillary test under that guideline. Refer to the dedicated death-determination section for the full framework; a simple adult checklist is insufficient.
