Abstract:
Objective To study the changes of low-frequency-component of intracranial pressure (ICP) fluctuation during intracranial hypertension. Methods 15 healthy mongrel dogs were used to make models of intracranial hypertension by arranging latex sacculus epidurally.The different amount of normal that was injected into latex sacculus led to fluctuation of ICP and alteration of intracranial volume. The pressures in ventricle and lumbar spinal canal were recorded continuously by baroceptor, and the changes of low-frequency-component of ICP fluctuation were studied by frequency-spectrum analysis. Results After increase of intracranial pressure and volume,pulse wave (M wave) with its frequency at 0.1～0.2 Hz showed continually. Conclusion Emerge of M wave may reflect some decrease of intracranial compliance and the beginning of volume compensation failure.
