26. Penumbra oxygen metabolism and acute neuroinflammation in ischemic stroke : MRI and PET imaging of a M2 occlusion model in rat
Sammanfattning : Acute ischemic stroke (AIS) is caused by the sudden occlusion of a major artery of the brain, and results in infarction and severe ischemia within affected brain regions. If ischemic regions are rapidly revascularized, the neurological disability resulting from AIS can be significantly reduced. LÄS MER
27. Experimental cardiopulmonary cerebral resuscitation : A study of cerebral perfusion with special reference to the postresuscitation disturbances
Sammanfattning : 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.

28. Neurochemical and cognitive aftermaths of surgery - studies on short- and long-term effects of surgery and anesthesia
Sammanfattning : Background: Each year, around the world, more than 230 million patients have surgery. Improvements in healthcare have resulted in older and sicker patients undergoing surgical interventions. As a result, surgical safety has be-come a global public-health concern. LÄS MER
29. Microdialysis : potentials and limitations
Sammanfattning : Despite improvements in operating technique and post-operative management, many patients undergoing liver transplantation still suffer post-operative complications, which may lead to graft loss or patient death. Patients are monitored closely post-operatively using blood chemistry, diagnostic imaging and liver biopsies to detect these complications including rejection and arterial- and portal vein thrombosis.

30. Ventricular fibrillation and defibrillation in patients with implantable cardioverter defibrillators
Sammanfattning : Since the introduction of the implantable cardioverter defibrillator for humans with malignant ventricular arrhythmias in 1980, over 50, 000 patients world wide have received this device. The implantation procedure is simple and resembles the implantation of an ordinary pacemaker. LÄS MER
