  1. 1. Cerebral Hemodynamics through Intracrnial Pressure

    Författare :Sima Shahsavari; Chalmers tekniska högskola; []
    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. Experimental cardiopulmonary cerebral resuscitation : with special reference to cerebral eicosanoid production and free radical scavengers

    Författare :Xiaoli Liu; Marianne Forsman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; cerebral resuscitation; reperfusion damage; oxidative injury; eicosanoid; free radical scavenger; neurological function; alkaline buffer; S-PBN; PBN; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi; Anaesthesiology;

    Sammanfattning : Reperfusion injury after restoration of spontaneous circulation (ROSC) is often considered one of the predominant factors in determining neurological outcome in cardiac arrest. Therefore one of the main targets of experimental and clinical studies has been to mitigate this reperfusion injury. LÄS MER

  4. 3. Neurointensive Care of Children with Severe Traumatic Brain Injury : Studies of barbiturate coma treatment, intracranial compliance, pressure autoregulation and optimal cerebral perfusion pressure

    Författare :Fartein Velle; Per Enblad; Shruti Agrawal; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Children; Refractory intracranial hypertension; Barbiturate coma; Intracranial compensatory reserve; autoregulation; cerebral microdialysis.; Neurokirurgi; Neurosurgery;

    Sammanfattning : Traumatic brain injury (TBI) is among the most common causes of death and acquired disability during childhood. Management guidelines for pediatric patients are usually extrapolated from adults. Specific pediatric studies are warranted to improve the TBI management in children. LÄS MER

  5. 4. 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

  7. 5. Optical Monitoring of Cerebral Microcirculation

    Författare :Peter Rejmstad; Karin Wårdell; Göran Salerud; Neda Haj-Hosseini; Kerstin Ramser; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

    Sammanfattning : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).
