Clinical study of continuous non-invasive cerebrovascular autoregulation monitoring in neurosurgical ICU.
Ultrasonic "time-of-flight" monitor (Vittamed) was used for continuous monitoring of intracranial blood volume (IBV) pulse, respiratory, slow waves and cerebrovascular autoregulation (CA). The objectives are to compare of invasively and non-invasively monitored slow intracranial waves and CA of ICU patients and to evaluate the phase shift between ABP and IBV respiratory waves as a possible esti...
متن کاملNovel Non-invasive Magnetic Resonance Imaging Methods in Cerebrovascular Disease
Neuroimaging is a critical component of patient care in multiple stages of cerebrovascular disease. Most imaging focuses on measurements of tissue or vascular structure, with comparatively less emphasis on function. Furthermore, imaging approaches that rely on exogenous contrast agents or ionising radiation are common and provide crucial information regarding treatment decisions; however, they ...
متن کاملContinuous monitoring of cerebrovascular autoregulation: a validation study.
BACKGROUND Continuous monitoring of dynamic cerebral autoregulation, using a moving correlation index of cerebral perfusion pressure and mean middle cerebral artery flow velocity, may be useful in patients with severe traumatic brain injury to guide treatment, and has been shown to be of prognostic value. OBJECTIVE To compare an index of dynamic cerebral autoregulation (Mx) with an index of s...
متن کاملThe Value of a BP Determination Method Using a Novel Non-Invasive BP Device against the Invasive Catheter Measurement
OBJECTIVE The aim of this study was to evaluate the accuracy of a new blood pressure (BP) measurement method (Pulse method). METHODS This study enrolled 45 patients for selective percutaneous coronary intervention (PCI) via right radial artery. A BP device using either oscillometric (Microlife 3AC1-1) or Pulse method(RG-BP11)was used. At the beginning of each PCI, intra-radial BP was measured...
متن کاملCerebrovascular reactivity and dynamic autoregulation in tetraplegia.
Humans with spinal cord injury have impaired cardiovascular function proportional to the level and completeness of the lesion. The effect on cerebrovascular function is unclear, especially for high-level lesions. The purpose of this study was to evaluate the integrity of dynamic cerebral autoregulation (CA) and the cerebrovascular reactivity in chronic tetraplegia (Tetra). After baseline, stead...
