Protective ventilation (association of a tidal volume < 8 ml/kg with a positive end expiratory pressure) is poorly used in severe brain-injured patients. Moreover, a systematic approach to extubation may decrease the rate of extubation failure and enhance outcomes of brain-injured patients. We hypothesized that medical education and implementation of an evidence-base care bundle associating protective ventilation and systemic approach to extubation can reduce the duration of mechanical ventilation in brain-injured patients.
The objective of this study is to determine whether a goal-directed therapy can reduce the incidence of delayed cerebral ischaemia after aneurysmal subarachnoid haemorrhage.
Cardiovascular disease (CVD) is an important public health problem that affects millions of people worldwide. Associations between risk factors, such as smoking, dyslipidaemia or hypertension, and prevalent CVD are well documented. However, few studies have investigated associations with onset of disease. The initial manifestation of CVD, for example an episode of unstable angina, is important because it influences the prognosis, the quality of life and the management of disease. Furthermore, the extent to which social deprivation, alcohol consumption or atrial fibrillation affects presentation of CVD is poorly understood and deserves further consideration. Most previous studies have considered CVD as a single entity. However, differences in aetiology between coronary phenotypes suggest that risk factors may not be shared across specific coronary phenotypes and their relative importance is likely to differ for each phenotype. Gaining knowledge of these differences could provide insights into the pathophysiology of specific forms of CVD and could eventually lead to modification of recommendations for patient management and disease prevention. We propose to use the linkage of the national registry of coronary events to general practice records in the Clinical Practice Research Database (CPRD), to investigate whether demographic, behavioral, and clinico-metabolic risk factors differentially influence the onset of specific types of CVD.
To assess the feasibility of a new neuromonitoring system (NeMoSystem including NeMo Probe and NeMo Patch) and the accuracy of the measurement values (cerebral blood flow (CBF); cerebral blood volume (CBV)) obtained.
Cardiac dysfunction can occur in aneurysmal subarachnoid haemorrhage and might impact patient's neurologic outcome Condition Aneurysmal subarachnoid haemorrhage World Neurosurgeon Federation Score ≥ III
To assess the feasibility of a new brain tissue probe for multi-parameter neuromonitoring (NeMo Probe) and the accuracy of measurement values. To demonstrate the ability of the NeMo probe to detect changes in cerebral hemodynamics and oxygenation during cerebrovascular events monitored with established methods including brain tissue oxygenation tension and microdialysis
Delayed cerebral vasospasm and secondary ischemic infarction are feared complications after aneurysmal subarachnoid hemorrhage (aSAH). To date, there is no effective therapy to prevent these ischemic complications. The arterial partial pressure of carbon dioxide (PaCO2) is one of the main determinants of cerebral blood flow (CBF) in healthy subjects. It is yet largely unknown, if and to what extent modulations of PaCO2 can influence CBF in patients after aSAH. The trial is a phase 1 study in which the feasibility of hypercapnia in SAH patients is tested. PaCO2 is gradually raised to 60 mmHg in 10 mechanically ventilated aSAH patients. Cerebral oxygen saturation measured by NIRS and CBF determined by an intracerebral thermodilution probe are the primary end points. If the feasibility is confirmed, this trial will be followed by a phase 2 dose finding study.
The purpose of this study is to determine the role of Proteomics and Metallomics in Cerebral Vasospasm following Subarachnoid Hemorrhage
The purpose of this study is to compare the profile of microRNA in cerebrospinal fluid from patients suffering subarachnoid hemorrhage with and without delayed cerebral ischemia.
