Correlation of intracranial pressure and transcranial Doppler resistive index after head trauma.
PURPOSE To investigate the usefulness of transcranial Doppler ultrasonography in the evaluation of intracranial pressure changes after head injury. METHODS Transcranial Doppler examinations and intracranial pressure measurements using intraparenchymal monitors were performed in 12 cases of closed head injury. Twenty-four sets of data, including the Glasgow Coma Scale, intracranial pressure, t...
متن کاملTranscranial Doppler Monitoring of Intracranial Pressure Plateau Waves
BACKGROUND Transcranial Doppler (TCD) has been used to estimate ICP noninvasively (nICP); however, its accuracy varies depending on different types of intracranial hypertension. Given the high specificity of TCD to detect cerebrovascular events, this study aimed to compare four TCD-based nICP methods during plateau waves of ICP. METHODS A total of 36 plateau waves were identified in 27 patien...
متن کاملThe use of transcranial Doppler pulsatility index to guide hyperosmolar therapy.
Management of intracranial hypertension is a major cornerstone of neurocritical care. Apart from traumatic brain injury, there are no clear guidelines for intracranial pressure (ICP) monitoring. The insertion of ICP monitors is an invasive procedure with inherent risks and could be contraindicated in case of severe coagulopathy. The transcranial Doppler (TCD) pulsatility index (PI) has emerged ...
متن کاملNoninvasive estimation of intracranial pressure using TCD
Usefulness of transcranial Doppler-derived cerebral hemodynamic parameters in the noninvasive assessment of intracranial pressure. Author Wakerley BR1, Kusuma Y, Yeo LL, Liang S, Kumar K, Sharma AK, Sharma VK. Content/Summary Abstract BACKGROUND: Transcranial Doppler (TCD) ultrasonography is a noninvasive bedside tool that can evaluate cerebral blood flow hemodynamics in major intracranial arte...
متن کاملDoppler-Derived Myocardial Performance Index in Healthy Children in Shiraz
Background: Assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. Ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia. Objective: A myocardial performance index (MPI) or Tei index has been developed for adult...
