Ultrasound-based Noninvasive Monitoring Methods for Neurocritical Care
The human brain lacks internal energy deposits and instead relies on a steady uninterrupted supply of blood for its metabolic needs. Short-lived disruptions in cerebral blood supply can cause permanent damage. Likewise, mechanical stress on the brain can cause life-threatening and long-lasting …

Optimization of the assessment of cerebral autoregulation in neurocritical care unit
… thesis. Results and Conclusions This PhD project carefully scrutinised currently used CA assessment methodologies in TBI patients, demonstrating significant relationships between ARI, Mx and TF phase. A new introduced wavelet-transform-based method, wPRx was validated and showed more stable result …

A retrospective review of complications in a South African neurocritical care unit over one year
Background: The establishment of a Neurocritical Care Unit (NCCU) is well described in offering benefits to patients1,2. These units are optimised to care for patients with pathologies involving the brain and spine. Complications peculiar to such units in Low- and Middle-income countries (LMICs) …

Implementation Strategies to Improve Critical Care Nurses' Knowledge of and Adherence to Evidence-Based Guidelines
Healthcare workers are responsible for providing evidence-based care to patients; however, many patients receive unnecessary or harmful care. Successful implementation of evidence-based guidelines can improve patient outcomes, particularly among vulnerable neuroscience patients. Focused efforts to …

Applications of Hybrid Diffuse Optics for Clinical Management of Adults After Brain injury
… study of the efficacy of DCS/DOS for monitoring neurocritical care patients during various medical interventions such as head-of-bed manipulation and induced hyperoxia; and (4) a first feasibility study for using DCS to study hemodynamics at high altitudes. The work presented in this dissertation …

Monitoring brain neurochemistry after brain trauma
… with existing clinical practices promises to aid neurocritical care by through near real-time metabolic data, thereby facilitating timely and effective clinical interventions. * Study I (Chapter 4) confirmed that the EC-QCL MIR sensor can monitor changes in glucose concentrations in–vitro. - Study …

A spectral approach for noninvasive estimation of intracranial pressure
… common time axis and deployed the system at the neurocritical care units at Boston Medical Center. The system has been used to collect 21 hours of high quality data from twelve patients over one year. We have improved upon past attempts at estimating ICP by implementing a model-based spectral …

Mechanisms of Cerebral Autoregulation in Traumatic Brain Injury
… we can target autoregulatory disturbance in the neurocritical care unit. This thesis addresses two aspects of these unknowns: 1) CA in the previously uncharacterised paediatric TBI (pTBI) population, and 2) the underlying biochemical mechanisms of CA disturbance following adult TBI. There is a …

The Measurement and Interpretation of Intracranial Pressure
… the most commonly monitored brain parameter in neurocritical care. Its rise, which may be benign, acute or chronic, is a common yet serious problem. ICP can rise because of a number of critical medical conditions such as hydrocephalus, traumatic brain injury, intracranial mass lesions, brain …

Clinical Applications of Neuromonitoring Following Acute Brain Injury
… and retrospective patient data in both neurocritical and general intensive care patients. Thirty neurotrauma patients and forty general intensive care patients with neurological complications were prospectively monitored after ABI. Retrospective patient data was harvested from a database …

Pressure, Compliance, and Autoregulation Studies in Intracranial Dynamics
Advancements in neuromonitoring technologies and techniques have led to novel explorations into the physiology and management of traumatic brain injury and normal pressure hydrocephalus. This thesis investigated these pathologies, under approved ethical procedures, with the aid of advanced …
