    Study Notes

    Intracranial Pressure (ICP)

    • Severe consequence: Untreated ICP can lead to brain herniation and death.
    • Causes: Bleeding (e.g., low INR), tumors, or anything increasing pressure within the skull.
    • Mechanism of brain herniation: Swelling pushes the medulla into the C1 and C2, collapsing it and stopping heartbeat and breathing.
    • Symptoms: Headache, nausea, vomiting (body's attempt to decrease pressure), hypertension.
    • Treatment: Elevate head of bed.
    • Warning sign: Sudden headache and vomiting upon waking can indicate increased risk of ICP.

    Child vs. Adult Neuro Systems

    • Rapid brain development in children: Children need whole milk until age 2 for myelin sheath development.
    • Fontanelles: Anterior fontanelles close by 18 months.
    • Increased ICP risk after 18 months: Cranium is sealed, increasing risk of brain injury from falls.
    • Long-term neurological deficits: Patients with unspecified neurological issues may experience bowel/bladder problems and inability to walk.

    Craniosynostosis

    • Suture closure: Early suture closure causes head deformation.

    Deformational Plagiocephaly

    • Flat head: Can result from prolonged laying in one position.

    Microcephaly

    • Cognitive impairments: Head circumference is 2 standard deviations below normal.

    Hydrocephalus

    • CSF buildup: Excess cerebrospinal fluid in the brain.
    • No bulging or firmness: A sunken head in babies indicates dehydration.
    • Treatment: Ventriculoperitoneal (VP) shunt.

    Intracranial Arteriovenous Malformations (AVMs)

    • Abnormal connections: Arteries and veins are abnormally connected.

    Meningitis

    • Viral or bacterial: Possible with or without sepsis.
    • Viral Meningitis: Self-limiting; avoid light and noise, use Tylenol for headaches.
    • Bacterial Meningitis: Can be fatal (septic); fever, headache, stiff neck (nuchal rigidity), photophobia, hemorrhagic rash, droplet precautions, antibiotics, isolation, more common in patients with shunts.
    • Kernig sign and Brudzinski sign: (Note: need specific references about these signs)
    • Important note: Droplet precautions are required.

    • Provide support: Intermittent suction, side rails up, common sense.

    Status Epilepticus

    • Aggressive treatment: IV fluids, oxygen, IV meds (lorazepam, diazepam). Stop the seizure activity.

    Febrile Seizures

    • Common in children (<7 years): Body temperature > 101.2°F.
    • Self-limiting: Anxiety-producing for parents.
    • EEG: Diagnostic testing.

    Antiepileptic Medications

    • Example: Carbamazepine.

    Head Trauma

    • Glasgow Coma Scale (GCS): Objective tool for head injury severity. GCS 8 or lower is critical.
    • GCS 8 or lower: Intubation required.
    • Posturing: Decorticate vs. decerebrate assess for injury severity.
    • Infant/toddler: High-risk due to larger heads.

    Headaches

    • Headache journal: To determine cause in children.
    • Abortive medicines: Taken at headache onset.

    Eye Disorders

    • Nystagmus: Abnormal eye movement (up and down) during lateral gaze.
    • Strabismus: "Cross-eye"; treated with occlusion therapy (covering stronger eye).

    Nasolacrimal Duct Obstruction

    • Unformed tear ducts: Fluid buildup, infection, redness, conjunctivitis.
    • Self-limiting: Usually resolves on its own.

    Periorbital Cellulitis

    • Eyelid/tissue infection: Very serious; requires prompt treatment.
    • Hospitalization: IV antibiotics and close monitoring.
    • Blindness risk: Untreated. Facial infections increase risk.

    Hearing Deficits

    • Suspect loss: Absent startle reflex or no response to verbal stimuli at 6 months old.

    Respiratory System (General)

    • Pediatric respiratory failure: Rapid onset, often more critical than in adults.

    Croup Disorders

    • Laryngotracheobronchitis: Most common, viral upper airway infection.
    • Treatment: Steroids, fluids, racemic epinephrine.
    • Spasmodic Laryngitis: (Usually <8yo); barking cough, afebrile, night-time; often self-limiting. Treatment: cool mist.

    Epiglottitis

    • Bacterial infection: Airway obstruction; medical emergency.
    • Clinical signs: Tripod positioning, drooling, "croaking" noise, steeple sign on x-ray.
    • Treatment: Immediate endotracheal tube, antibiotics.

    Pertussis

    • Whooping cough: Long duration; begins with cold symptoms, progressing to severe coughing episodes (2-6 weeks).

    Pneumonia

    • Lower airway infection/inflammation: Bacterial or viral (community or hospital-acquired).
    • Symptoms: Fever, tachypnea, cough, nausea/vomiting, irritability/restlessness, lethargy.
    • Treatment: Antibiotics if bacterial; monitor for distress.

    RSV Bronchiolitis

    • Degenerative condition: Symptoms worsen over 2 days; severe congestion, thick mucus.
