1. Pressure autoregulation of cerebral blood flow in traumatic brain injury and aneurysmal subarachnoid hemorrhage
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
2. Neurointensive Care of Children with Severe Traumatic Brain Injury : Studies of barbiturate coma treatment, intracranial compliance, pressure autoregulation and optimal cerebral perfusion pressure
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
3. Endothelial Nitric Oxide in the Control of Glomerular Hemodynamics
Sammanfattning : The afferent arteriole of the kidney is a unique vascular segment: it is the effector of the renal hemodynamic autoregulation. The use of the isolated, perfused juxtamedullary nephron preparation makes it possible to visualize the afferent arteriole while preserving its tissue surroundings and the functional integrity of the nephron.

4. Aspects on Mechanisms, Treatment and Outcome in Severe Traumatic Brain Injury
Sammanfattning : Traumatic brain injury (TBI) is a leading cause for mortality and morbidity worldwide. The primary injury has great impact on patient outcome and cannot be cured, but attentive neurointensive care (NIC) may reduce detrimental secondary brain injuries and is the focus of this thesis.

5. The cerebral circulation in preeclampsia : abnormalities in autoregulation and perfusion
Sammanfattning : Background: Eclampsia continues to be a major cause of maternal death. Abnormal cerebral blood flow and autoregulation may play an important role in the causation. Doppler ultrasound now allows assessment of the pathophysiology of preeclampsia, and the mechanisms of action of drugs used to treat it. LÄS MER
