  • Hydrocephalus
    • A condition caused by an imbalance in the production and absorption of CSF in the ventricular system
    • When production exceeds absorption, CSF accumulates, usually under pressure, producing dilation of the ventricles
    NORMAL= CHILD= 60-100mL
  • Types of hydrocephalus
    • Communicating
    • Noncommunicating
  • Communicating hydrocephalus

    • Impaired absorption within the subarachnoid space
    • Interference of CSF within ventricular system does not occur
  • Noncommunicating hydrocephalus

    Obstruction of CSF flow within ventricular system
  • Hydrocephalus clinical manifestations
    • Abnormal rate of head growth
    • Bulging fontanelle
    • Tense anterior fontanelle (often bulging and non-pulsatile)
    • Dilated scalp veins
    • Macewen's sign ("cracked pot")
    • Frontal bossing
    • Irritability and lethargy with varying LOC
    • Abnormal infantile reflexes
    • Possible cranial nerve damage
    • Setting sun sign
    • Sluggish and unequal pupils
    • Signs of increased ICP: Headache on awakening with improvement following emesis, Papilledema, Strabismus, Ataxia, Large head, Irritability, Lethargy, Apathy, confusion
  • Hydrocephalus diagnosis
    1. Level II ultrasonography of the fetus will allow a prenatal diagnosis (Transuterine placement of Ventriculoamniotic shunts during late pregnancy is still being developed as a treatment modality)
    2. Physical examination (HC)
    3. CT scan (diagnose most cases postnatally)
    4. MRI (if complex lesion is suspected)
  • Hydrocephalus treatment
    1. Surgical Intervention: VP shunt(from ventricles to peritoneal cavity), VA shunt(right atrium), Ventriculopleural shunt(pleural cavity), Ventriculostomy (non-shunting procedure), Surgical removal of obstruction (if cause is removable such as tumor/ hematoma)
    2. Medication: Acetazolamide
  • Hydrocephalus nursing management - preoperative
    • Assess head circumference, fontanelles, cranial sutures, and LOC; check also for irritability, altered feeding habits and a high-pitched cry
    • Firmly support the head and neck when holding the child
    • Provide skin care for the head to prevent breakdown
    • Give small, frequent feedings to decrease the risk of vomiting
    • Encourage parental-newborn bonding
  • Hydrocephalus nursing management - postoperative
    • Assess for signs of increased ICP and check for: head circumference (daily), Anterior fontanelle for size and fullness, and behavior
    • Administer prescribed medications which may include antibiotics to prevent infection and analgesics for pain
    • Provide shunt care: Monitor for shunt infection and malfunction, Prevent infection (usually from staphylococcus epidermis or aureus)
    • Monitor for shunt overdrainage (headache, dizziness and nausea)- may lead to slit ventricle syndrome
  • Hydrocephalus complications
    • Infections and malfunction (shunt)
    • Subdural hematoma (too rapid reduction of CSF)
    • Peritonitis
    • Abdominal abscess
    • Perforation of organs
    • Fistulas
    • Hernias
    • Ileus
