Transcranial Doppler ultrasonography in anaesthesia and intensive care [PDF]

British Journal of Anaesthesia, 2004
Transcranial Doppler ultrasonography (TCD) was introduced in 1982 by Aaslid and colleagues 5 as a non-invasive technique for monitoring blood flow velocity (FV) in the basal cerebral arteries. It is now increasingly being used in anaesthesia and intensive care for research as well as in clinical practice.

Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

Experimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

Cerebral haemodynamic responses to inspiratory muscle work

Experimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Development history of cerebral autoregulation

Chinese Journal of Contemporary Neurology and Neurosurgery, 2021
Cerebral autoregulation (CA) refers to the ability to maintain cerebral blood flow (CBF) relatively constant under the condition of systemic arterial blood pressure (ABP) fluctuation.

No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

Experimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Transcranial Doppler Ultrasonography as an Early Outcome Forecaster Following Severe Brain Injury

, 2006
Knowledge of post-traumatic cerebral haemodynamic disturbances might be beneficial for predicting the management outcome when measuring the basal cerebral arteries blood flow velocity by ultrasonic transcranial Doppler device immediately after severe ...

An unusual unifocal presentation of Castleman’s disease in a young woman with a detailed description of sonographic findings to reduce diagnostic uncertainty: a case report [PDF]

, 2013
Background: Castleman’s disease is a rare lymphoproliferative disorder. It typically presents as mediastinal masses and causes a wide range of clinical symptoms.

Transcranial Doppler ultrasonography to evaluate cerebral hemodynamic changes in neurocysticercosis

Arquivos de Neuro-Psiquiatria
Background Arteritis is a complication of neurocysticercosis (NCC), which is not well known and could trigger strokes. The transcranial Doppler ultrasound (TCD) is a noninvasive method for detecting, staging, and monitoring cerebrovascular ...
