  1. 1. Experimental cardiopulmonary cerebral resuscitation : A study of cerebral perfusion with special reference to the postresuscitation disturbances

    Author : Ala Nozari; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac arrest; cardiopulmonary resuscitation; cerebral blood flow; post-resuscitation period; epinephrine; vasopressin; aortic occlusion; isoprostane; Kirurgi; Surgery; Kirurgi; Anestesiologi; Anaesthesiology;

    Abstract : Ischemic neuronal injury continues to be a major delimiting factor in achieving successful clinical outcomesafter resuscitation from cardiac arrest. In this thesis, a pig model of cardiopulmonary resuscitation (CPR) wasused to address the effects of different interventions on cerebral blood flow and oxygenation during CPR and theinitial postresuscitation period.

  2. 2. Brain Tissue Oxygenation in Traumatic Brain Injury : Experimental and Clinical Studies

    Author : Karlis Purins; Anders Lewén; Per Enblad; Oliver Sakowitz; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain tissue oxygenation; Cerebral metabolism; Traumatic brain injury; Cerebral ischemia; Threshold levels; Neurovent-PTO; Microdialysis; Neurosurgery; Neurokirurgi;

    Abstract : Traumatic brain injury (TBI) is a major cause of death and disability. TBI is frequently followed by cerebral ischemia which is a great contributor to secondary brain damage. The main causes of cerebral ischemia are pathophysiological changes in cerebral blood flow and metabolism. READ MORE

  3. 3. Hyperglycemia in Experimental Cerebral Ischemia

    Author : Maria Molnar; Fredrik Lennmyr; Sten Lindahl; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain ischemia; cardiac arrest; cytokines; gene expression; glucose; hyperglycemia; microarray; oxidative stress; pigs; rats; reperfusion; resuscitation S100β; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård; Neuroscience; Neurovetenskap;

    Abstract : Cerebral ischemia is a life-threatening condition associated with a substantial morbidity and mortality. Hyperglycemia, a common coexisting phenomenon in both stroke and cardiac arrest (CA), may further aggravate ischemic brain injury. To date, the therapeutic possibilities are lim-ited and the search for new treatment modalities is warranted. READ MORE

  4. 4. Mathematical Modelling of Cerebral Metabolism : From Ion Channels to Metabolic Fluxes

    Author : Nicolas Sundqvist; Gunnar Cedersund; Maria Engström; Roland Nilsson; Sebastian Sten; João Duarte; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The brain is the most metabolically active organ in the human body and therefore rely on a continuous supply of oxygen and glucose. Neuronal stimulation in specific regions of the leads to the firing of action potentials, a process facilitated by voltage-gated ion channels in the neurons’ cell membranes. READ MORE

  5. 5. Post Cardiac Arrest Care : Evaluation of prognostic tools, Patient outcomes and Relatives’ experiences at 6 months after the event

    Author : Ewa Wallin; Sten Rubertsson; Marja-Leena Kristofferzon; Silvana Naredi; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac arrest; hypothermia; neurological outcome; cerebral oxygenation; MRI; relatives; Medicinsk vetenskap; Medical Science;

    Abstract : The overall aim of the present thesis was to study post-resuscitation care of cardiac arrest (CA) patients treated with target temperature management 33°C with a focus on evaluation of two prognostic tools: variations in cerebral venous saturation and acute magnetic resonance imaging (MRI) findings on the brain post-CA. An additional aim was to investigate patients’ neurological outcome and relatives’ experiences 6 months after the event. READ MORE
