2. 1. Cerebral Hemodynamics through Intracrnial Pressure

   Author : Sima Shahsavari; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Cerebral CT - and MRI perfusion: Techniques and clinical application in iNPH

   Author : Doerthe Ziegelitz; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebral perfusion; idiopathic normal pressure hydrocephalus; computed tomography perfusion; dynamic suceptibility contrast MRI;

   Abstract : Idiopathic normal pressure hydrocephalus (iNPH) is a disorder of the elderly, defined by slowly progressive impairment of gait and balance, cognitive decline, and incontinence. Disturbance of the cerebrospinal fluid (CSF) dynamics results in ventriculomegaly without intracranial pressure increase. READ MORE

5. 3. 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.

6. 4. Cerebral Perfusion and Metabolism during Experimental Extracorporeal Circulation

   Author : Ove Jonsson; Stefan Thelin; Fredrik Lennmyr; Sven-Erik Ricksten; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral perfusion; Experimental brain research; Experimentell hjärnforskning; Thoraxkirurgi; Thorax Surgery;

   Abstract : Neurologic injuries are major causes of mortality and morbidity after cardiac surgery. This thesis aimed to investigate cerebral metabolism and perfusion abnormalities in pigs during hypothermic circulatory arrest, selective antegrade cerebral perfusion (SACP) and extracorporeal circulation following progressive venous stasis.

7. 5. Cerebral Perfusion during Cardiopulmonary Bypass

   Author : Thomas Tovedal; Fredrik Lennmyr; Stefan Thelin; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Impaired superior vena cava (SVC) cannula outflow during cardiopulmonary bypass (CPB) is a frequent issue, often manifested by only marginal changes in routine monitoring parameters. Nevertheless, significant impact on cerebral perfusion may result. READ MORE
