頭蓋内圧比較表

Comparison of Continuous Non-Invasive and Invasive Intracranial Pressure Measurement Study Start Date: January 2014 Estimated Completion Date: September 2015 Interventions • Device: DPOAE • Device: Tympanic membrane displacement (TMD) Inclusion criteria • Clinical diagnosis of suspected symptomatic hydrocephalus or idiopathic intracranial hypertension (pseudotumor cerebri) • ICP monitoring via 25-ga needle in an existing shunt reservoir or ICP monitoring via spinal catheter has been recommended on the basis of standard clinical criteria • Capable of providing valid signed informed consent • Normal middle-ear function as determined by tympanometry • DPOAE meet criteria that are required for the research • Acoustic stapedial reflex meets criteria that are required for the research • Subject is willing and able to return for the study Exclusion criteria • Subject is pregnant • Subject lacks decision-making capacity • Subject is unwilling or unable to return for the study • Prior middle-ear disease or surgery, with the exception of tympanostomy tubes that have been removed and are healed • Participating in the study would significantly delay or interfere with the subject's healthcare • Subject has excess ear wax that cannot be removed safely and could potentially be pushed onto the ear drum by the insertion of the ear plugs needed for the testing • The TMD or DPOAE do not respond to a change in posture from lying flat to standing up, which means that the anatomic connection between the inner ear and the CSF is absent Study Locations And Contact Information • Sinai Hospital of Baltimore, Baltimore Maryland Contact: Alanvin Orpia, BSN, RN 410-601-0960h. Description: This research is being done to determine the accuracy of two noninvasive methods of measuring the pressure of the cerebrospinal fluid (CSF), also known as intracranial pressure or ICP.
