The Effect of Stellate Ganglion Block on Intracranial Pressure Predicted by Ultrasonographic Assessment of Optic Nerve Sheath Diameter

Completed
Conditions
Intracranial Pressure
Pain
Interventions
Procedure: ultrasonographic measurement of optic nerve sheath diameter
Registration Number
NCT01840995
Lead Sponsor
Yonsei University
Brief Summary

The stellate ganglion block increase cerebral blood flow, as the consequence of that, it has the potential to cause an increase of intracranial pressure (ICP). Previous studies have proposed that ultrasonographic measurements of the optic nerve sheath diameter (ONSD) correlate with signs of increased ICP. Therefore, this study is aim to confirm the increased ICP by ultrasonographic measurement of ONSD after the stellate ganglion block.
