    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intracranial dynamics; Baroreceptor reflex; Secondary brain injury; Traumatic brain injury; Collapsible tubes; Intracranial pressure; Cushing reflex; Pulse wave propagation; Cerebral autoregulation; Cerebral compliance; Mathematical modelling;

    Sammanfattning : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainly focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. LÄS MER

  3. 2. Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"

    Sammanfattning : "Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. LÄS MER

  4. 3. Noninvasive assessment of cerebral circulation before, during and after carotid surgery

    Författare :Helene Zachrisson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal carotid artery disease; cerebrovascular hemodynamics; Carotid thrombendarterectomy; Duplex ultrasound; transcranial Doppler; Internal carotid artery disease;

    Sammanfattning : Non-invasive ultrasound investigations were evaluated in patients with carotid artery stenosis in comparison with radiological disease gradations and perioperative blood pressure measurements. The aim was to assess cerebrovascular hemodynamics before, during and after carotid thrombendarterectomy (CEA) in relation to the clinical outcome of the surgical intervention. LÄS MER

  5. 4. Pathophysiological characterization of traumatic brain injury using novel analytical methods

    Författare :Cecilia Åkerlund; David Nelson; Anders Holst; Ari Ercole; Niklas Marklund; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Intracranial pressure; clustering; Medicinsk teknologi; Medical Technology;

    Sammanfattning : Severity of traumatic brain injury is usually classified by Glasgow coma scale (GCS) as “mild”, "moderate" or "severe’, which does not capture the heterogeneity of the disease. According to current guidelines, intracranial pressure (ICP) should not exceed 22 mmHg, with no further recommendations concerning individualization or tolerable duration of intracranial hypertension.
