  1. 1. Cerebral circulation and the sympathetic nervous system in patients with traumatic brain injury or subarachnoid hemorrhage

    Författare :Silvana Naredi; Göteborgs universitet; []
    Nyckelord :traumatic brain injury; brain edema; microcirculation; intracranial pressure; epo-prostenol; norepinephrine; subarachnoid hemorrhage; sympathetic nervous system; clonidine;

    Sammanfattning : Maintenance of adequate cerebral microcirculation is necessary to avoid cerebral ischemia after severe traumatic brain injury and non-traumatic subarachnoid hemorrhage. After severe traumatic brain injury the blood-brain-barrier is disrupted and transcapillary leakage will contribute to the development of vasogenic brain edema. LÄS MER

  3. 2. Trauma - logistics and stress response

    Författare :Camilla Brorsson; Silvana Naredi; Anders Sylvan; Per Dahlqvist; Mikael Bodelsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; multiple trauma; hydrocortisone; adrenal insufficiency; hypnotics and sedatives; citric acid; glycerol; saliva; liver; colorectal surgery;

    Sammanfattning : Background: Trauma is a major cause of death and disability. Adverse events, such as prolonged prehospital time, hypoxia, hypotension and/or hyperventilation have been reported to correlate to poor outcome.Adequate cortisol levels are essential for survival after major trauma.

  4. 3. Subarachnoid haemorrhage : clinical and epidemiological studies

    Författare :Cecilia Lindgren; Silvana Naredi; Magnus Hultin; Lars-Owe Koskinen; Elisabeth Ronne-Engström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subarachnoid haemorrhage; ADMA; Cortisol; EEG; inflammation; epidemiology; endothelium; arginine; anestesiologi; Anaesthesiology; neurokirurgi; Neurosurgery; epidemiologi; Epidemiology;

    Sammanfattning : Background: Subarachnoid haemorrhage (SAH) is a severe stroke that in 85% of all cases is caused by the rupture of a cerebral aneurysm. The median age at onset is 50-55 years and the overall mortality is approximately 45%.Sufficient cortisol levels are important for survival. LÄS MER

  5. 4. Metabolic and Endocrine Response in the Acute Stage of Subarachnoid Hemorrhage

    Författare :Christoffer Nyberg; Elisabeth Ronne Engström; Torbjörn Karlsson; Lars Hillered; Silvana Naredi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subarachnoid hemorrhage; Energy Expenditure; BNP; Animal Model; Cortisol; Microdialysis; Neurokirurgi; Neurosurgery;

    Sammanfattning : The rupture of an aneurysm in subarachnoid hemorrhage (SAH) is a dramatic event causing a severe impact on the brain and a transient or permanent ischemic condition. Several types of responses to meet the challenges of SAH have been found in the acute phase, including activation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system, elevated levels of brain natriuretic peptide (BNP), and disturbances in cerebral and systemic metabolism.

  7. 5. Severe cerebral emergency : aspects of treatment and outcome in the intensive care patient

    Författare :Marie Rodling Wahlström; Silvana Naredi; Sven-Erik Gisvold; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; severe traumatic brain injury; intracranial pressure-targeted therapy; albumin; prostacyclin; endothelial dysfunction; pro-inflammatory cytokines; subarachnoid haemorrhage; asymmetric dimethylarginine; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anaesthesiology; anestesiologi;

    Sammanfattning : Severe Traumatic Brain Injury (TBI) and aneurysmal Subarachnoid Hemorrhage (SAH) are severe cerebral emergencies. They are common reasons for extensive morbidity and mortality in young people and adults in the western world. LÄS MER
