Terms in this set (65)

-enlarged head and we must shunt to drain into the peritoneal cavity
-biggest concern with shunt is infection and blockage so we want to teach early symptoms of increased icp.
-shunt must be changed as they grow, infected or blocked and this puts them at risk for infection.
-experience delayed growth development
-
Imbalance in the production and absorption of CSF in the ventricular system
Produces excess of CSF in ventricles
Causes passive dilation of the ventricles
Causes head enlargement w/ fontanelles open
Communicating- CSF ventricles to subarachnoid space
Obstructive-passage blocked
Congenital or acquired

Hydrocephalus Assessment
Prominent scalp veins fluid pressure
Forehead "bossing"
Enlarged fontanelles increased icp in infants will have bulging fontanelles
"Sunset" eyes
Shrill cry
Hyperactive reflexes
Separated suture line
Increased OFC
Lethargy/irritability
VS changes

Hydrocephalus Management
Tx = surgical (few exceptions)
Obstruction repair
Removal of tumor
Ventriculoperitoneal shunt (VP shunt)- drains CSF into peritoneum
May become infected or obstructed
Changes in size
Acetazolamide- carbonic anhydrase inhibitor, promotes bicarb excretion which reduces intracranial pressure

-will not be tested on medication

-first 24 hrs after procedure is highest rate of infection but they can get an infection at any time in shunts

Hydrocephalus:Nursing interventions
Observe for increasing ICP, early and late signs
Infants
Older children
Nutrition (sucking would affect pressure, failure to thrive, nausea) if eating and stop suddenly we will begin to assess if there is anything wrong with the shunt
Prep for procedures
Postoperative care
Family support (lifelong, look at positives, teach s&s,
