    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

  3. 2. Biochemical and genetic markers after subarachnoid haemorrhage

    Författare :Ludvig Z Csajbok; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subarachnoid haemorrhage; biochemical marker; genetic marker; outcome;

    Sammanfattning : ABSTRACT Background: Subarachnoid haemorrhage is a devastating disease with high morbidity and mortality despite novel treatment options are available. There are no established methods to measure the brain damage occurring due to the bleed and its complications and to predict early neurological outcome of the disease. LÄS MER

  4. 3. On receptor changes in cerebral arteries after subarachnoid haemorrhage

    Författare :Jacob Hansen-Schwartz; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Pharmacological sciences; subarachnoid haemorrhage; reverse transcriptase polymerase chain reaction; in vitro pharmacology; organ culture; Endothelin receptors; 5-HT receptors;

    Sammanfattning : Overall the aim has been to characterise the in vitro upregulation of the 5-hydroxytryptamine 1B/1D (5-HT(1B/1D)) and endothelin (ET) receptors in the cerebral circulation as well as demonstrating phenotypic changes in a pathophysiological model mimicking subarachnoid haemorrhage. The first part describes receptor upregulation using organ culture of whole vessel segments from both rat and man. LÄS MER

  5. 4. Strain echocardiography in the critically ill patient : Studies in patients with septic shock and subarachnoid haemorrhage

    Författare :Keti Dalla; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Strain echocardiography in ICU patients; Left ventricle; Right ventricle; Septic shock; Subarachnoid haemorrhage; Norepinephrine;

    Sammanfattning : In this thesis, strain echocardiography by two-dimensional speckle tracking imaging (2D-STI), was used for the evaluation of left ventricular (LV) and right ventricular (RV) function in critically ill patients with septic shock and subarachnoid haemorrhage. The aims were to: 1) investigate the value of strain echocardiography for the early detection of LV and RV dysfunction not diagnosed with conventional echocardiography in severe sepsis and septic shock, 2) to study the effects of norepinephrine on RV systolic function and pulmonary haemodynamics in patients with norepinephrine-dependent septic shock 3) evaluate the use of strain echocardiography for detection of myocardial injury in patients with subarachnoid haemorrhage (SAH) and 4) study the impact of general anaesthesia and positive pressure ventilation (PPV) on RV and LV myocardial longitudinal strain.

  7. 5. Clinical Studies in the Acute Phase of Subarachnoid Haemorrhage

    Författare :Maria Zetterling; Elisabeth Ronne Engström; Ola Nilsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subarachnoid haemorrhage; microdialysis; brain energy metabolism; brain glucose; pyruvate; amino acids; cerebral oedema; ACTH; cortisol; Neurosurgery; Neurokirurgi; Neurosurgery; Neurokirurgi;

    Sammanfattning : Patients admitted in similar clinical condition after spontaneous SAH can develop very different clinical courses. This could depend on the severity of the initial global ischemic brain injury at ictus. LÄS MER
