    Sammanfattning : Aneurysmal subarachnoid hemorrhage (SAH) is frequently complicated by delayed cerebral ischemia (DCI), contributing to poor outcome. Particularly for patients in poor neurological state, prediction of the acute clinical course is difficult, as is the early detection of DCI. LÄS MER

  3. 2. Pressure autoregulation of cerebral blood flow in traumatic brain injury and aneurysmal subarachnoid hemorrhage

    Författare :Ulf Johnson; Per Enblad; Lars-Owe Koskinen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral blood flow; autoregulation; traumatic brain injury; subarachnoid hemorrhage; Neurosurgery; Neurokirurgi;

    Sammanfattning : The ability of the brain to keep a stable and adequate cerebral blood flow (CBF) independently of fluctuations in systemic blood pressure is referred to as cerebral pressure autoregulation (CPA). When the brain is injured by trauma or hemorrhage, this ability may be impaired, leaving the brain vulnerable to events of high or low blood pressure. LÄS MER
