179. Increased Intracranial Pressure
The brain, while well protected by the solid bony cranium, is highly susceptible to pressure
that may accumulate within the enclosure. Volume and pressure must remain constant within the brain. A change in the size of
the brain, such as occurs with edema, or increased volume of intracranial blood or cerebrospinal fluid without a compensatory
change, will lead to an increase in intracranial pressure, which may be life-threatening. An early sign of increased intracranial
pressure, vomiting, can become excessive as pressure builds up and stimulates the medulla in the brainstem, which houses the
vomit center. Children with open fontanels (posterior closes at 2 to 3 months; anterior closes at 12 to 18 months) compensate for
intracranial pressure changes by skull expansion and subsequent bulging fontanels. Once...
