Non-invasive ONSD-based Neuromonitoring in a Neurointensive Care Setting
TraumaBrain2 moreIntensive care patients with established invasive intracranial neuromonitoring due to neurotrauma are subjected to a repeated non-invasive sonographic recording of the optic-nerve-sheath-diameter (ONSD). The recorded images are analyzed through a machine-learning-algorithm and an experienced ultrasound operator. Results are correlated to the parallel recorded intracranial pressure (ICP). The study aims to establish ONSD as a supplementary for raised ICP.

Outcomes Associated With Application of a Normothermia Protocol in Patients With Severe Neurological...
Subarachnoid HemorrhageSevere Traumatic Brain InjuryWhen fever is present in patients with stroke, traumatic brain injury (TBI), or brain hemorrhage, it has been associated with worse outcomes including larger areas of tissue death, increased length of stay, worse degree of coma, lower ability to function, and higher mortality. Both adult and pediatric TBI national guidelines state that maintenance of normal body temperature should be a standard of care. However, no further standards or options are presented to specifically guide practice. The current ischemic stroke guidelines state that fever should be treated with fever-reducing agents and offer "cooling devices" as an option but do not provide specifics to guide practice. Over 50% of patients in the Neurosurgical Intensive Care Unit (ICU) at Harborview Medical Center develop fever during the course of their stay. With elevated temperatures the body consumes more oxygen than if the temperature was normal, causing less oxygen to be available to the brain. This may lead to injury of the brain cells and a diminished capacity for healing. Thus, temperature management in neurologically vulnerable patients is both a prevalent and problematic challenge. Based on this information the goal of the present proposal is to evaluate if 1) A standardized, step-wise approach to temperature management using a Normothermia Protocol is successful in achieving and maintaining normal temperature in Neurosurgical ICU patients; and 2) If maintenance of normal temperature will be associated with fewer episodes of diminished responsiveness in their neurological exams as evidenced by a measure of depth of coma, as measured by the Glasgow Coma Score (GCS) compared to a control group treated according to usual care.
Early Tracheostomy in Ventilated Stroke Patients 2
Ischemic and Hemorrhagic StrokeSubarachnoid HemorrhagePatients with severe ischemic and hemorrhagic strokes, who require mechanical ventilation, have a particularly bad prognosis. If they require long-term ventilation, their orotracheal tube needs to be, like in any other intensive care patient, replaced by a shorter tracheal tube below the larynx. This so called tracheostomy might be associated with advantages such as less demand of narcotics and pain killers, less lesions in mouth and larynx, better mouth hygiene, safer airway, more patient comfort and earlier mobilisation. The best timepoint for tracheostomy in stroke, however, is not known. Preliminary data from a pilot study of early tracheostomy in patients with hemorrhagic or ischemic stroke suggest that such patients may also have improved survival and long-term functional outcomes, but a large, multicenter clinical trial is needed to confirm these findings.
Remote Ischemic Pre-conditioning in Subarachnoid Hemorrhage
Brain AneurysmsThe purpose of the study is to investigate if briefly stopping blood flow to the patient's leg will lead to the patient's body being better able to tolerate possible decreased blood flow to regions of the brain which otherwise frequently happens after subarachnoid hemorrhage. Previous studies show that various organs such as the heart, brain or kidney can tolerate longer periods of decreased blood flow if prior to that insult shorter periods of decreased blood flow were experienced.
