  2. 1. Detection and haemodilutive treatment of cerebral arterial vasospasm and delayed ischaemia after Aneurysmal Subarachnoid Haemorrhage

    Author : Anders Ekelund; Neurokirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral oxygen delivery.; cerebral blood flow; hypervolaemic haemodilution; isovolaemic haemodilution; transcranial cerebral oximetry; transcranial Doppler ultrasound; delayed ischaemic deficit; Aneurysmal subarachnoid haemorrhage; cerebral arterial vasospasm; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. READ MORE

  4. 2. Optical Monitoring of Cerebral Microcirculation

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

    Abstract : 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).

  5. 3. Cardiopulmonary Resuscitation : Pharmacological Interventions for Augmentation of Cerebral Blood Flow

    Author : Jakob Johansson; Sten Rubertsson; Rolf Gedeborg; Sven-Erik Gisvold; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; Adrenaline epinephrine ; Cardiac arrest; Cardiopulmonary resuscitation; Cerebral blood flow; Guidelines; Post-resuscitation period; Vasopressin; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård;

    Abstract : Cardiac arrest results in immediate interruption of blood flow. The primary goal of cardiopulmonary resuscitation (CPR) is to re-establish blood flow and hence oxygen delivery to the vital organs. READ MORE

  6. 4. Bedside monitoring of cerebral energy metabolism using intracerebral microdialysis during neuro intensive care

    Author : Nils Ståhl; Neurokirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; Neurologi; neuropsychology; Neurology; glycerol.; glutamate; pyruvate; lactate; glucose; hyperglycaemia; intensive care; brain injury; Human; cerebral microdialysis; neurophysiology;

    Abstract : In clinical situations with raised intracranial pressure (ICP) and impending insufficient cerebral blood flow (ischaemia), bedside information about energy metabolism in the brain would be helpful. Microdialysis is a technique that makes it possible to monitor the interstitial concentrations of various compounds in an organ. READ MORE

  7. 5. Augmentation of vital organ blood flow during experimental cardiopulmonary resuscitation

    Author : Rolf Gedeborg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac arrest; cardiopulmonary resuscitation; epinephrine; high-dose epinephrine; buffer; cerebral blood flow; post-resuscitation period; aortic occlusion; Kirurgi; Surgery; Kirurgi; Anestesiologi; Anaesthesiology;

    Abstract : Clinical outcome from cardiac arrest remains poor. If the time from arrest to restoration of spontaneous circulation can be shortened and resuscitation techniques improved so that higher blood flow and oxygen delivery to vital organs is achieved, it is possible that the outcome from cardiac arrest could improve.
