Abstract:
Children with high intracranial pressure can occur in a variety of neurological diseases，is an important cause of secondary brain injury，the disease has a high time sensitivity，and is easy to miss the best treatment time.Invasive monitoring of intracranial pressure has many complications and contraindications，which has promoted the clinical application of noninvasive monitoring of intracranial pressure.The optic nerve sheath has a special anatomical structure，and it is surrounded by cerebrospinal fluid，which is connected with the ventricular system of the brain.When intracranial pressure increases，the optic nerve sheath will be thickened.Ultrasound measurement of the optic nerve sheath diameter can provide non-invasive，real-time and repeated assessment of intracranial pressure.The diameter of optic nerve sheath in children was affected by race，age，sex，transverse diameter of eyeball，openness of fontanel，skull compliance，plasticity，disease course，interobserver variability and other factors.Although there are many influencing factors，compared with invasive monitoring，ultrasonic measurement of optic nerve sheath diameter may be a safe and non-invasive bedside tool to fill，which can evaluate intracranial pressure earlier and faster in real time，and have important role in children with neurocritical diseases.
