1. 16. Nitric oxide in experimental sepsis

   Författare :Peter Dahm; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensive care; Nitric oxide; Sepsis; NO inhalation; Endotoxin; Acute lung injury; ARDS; Nitric oxide synthase; L-NMMA; L-NAME; Anestesiologi; Anaesthesiology; Pigs; intensivvård;

   Sammanfattning : Nitric oxide (NO) is important in the control of blood pressure and organ perfusion. In septic shock, NO produced by inducible NO-synthase (NOS) has been claimed to mediate pathological vasodilation and cell injury, while NO produced by constitutive NOS may be protective in counteracting hypoperfusion and organ injury.

3. 17. Assessment of the Cerebral Ischemic/Reperfusion Injury after Cardiac Arrest

   Författare :Erik Mörtberg; Sten Rubertsson; Eldar Søreide; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensive care; Intensivvård; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård;

   Sammanfattning : The cerebral damage after cardiac arrest is thought to arise both from the ischemia during the cardiac arrest but also during reperfusion. It is the degree of cerebral damage which determines the outcome in patients. This thesis focuses on the cerebral damage after cardiac arrest. LÄS MER

4. 18. Mesentric hemodynamics and effects of angiotensin II during circulatory stress

   Författare :Mats Laesser; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Renin-angiontensin system; angiotensin II; intestines; hemodynamics; perfusion; hemorrhage; hypovolemia; endotoxemia;

   Sammanfattning : Mesenteric hypoperfusion and ischemia is considered to be deleterious to the intestinal mucosal barrier function and it is suggested that the renin-angiotensin system plays a pivotal role in the regulation of mesenteric perfusion.The present thesis examines the effects of the specific AT1 receptor blocker candesartan on mesenteric hemodynamics during acute hypovolemia and endotoxinemia.

5. 19. On the metabolic consequenses of abdominal compartment syndrome

   Författare :Per Skoog; Lars Norgren; Kjell Jansson; Erik Solligård; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intra-abdominal hypertension; intra-abdominal metabolism microdialysis; laserdoppler flowmetry; lactate; pyruvate; glycerol; lactate pyruvate ratio; ruptured abdominal aortic aneurysm; Kirurgi; Surgery;

   Sammanfattning : Intra-abdominal hypertension (IAH) and the progression to abdominal compartment syndrome (ACS) are known complications of vascular and abdominal surgery, trauma, sepsis, and burns. ACS is associated with high mortality. LÄS MER

7. 20. Regional oxygenation in cardiac surgery. Influence of temperature, pump flow and insulin

   Författare :Lena Lindholm; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiopulmonary bypass; cardiac surgery; regional oxygenation; venous oxygenation; splanchnic oxygenation; insulin; vasodilation; temperature; pump flow;

   Sammanfattning : Surgical trauma triggers neural, endocrine and inflammatory reactions with subsequent alterations in systemic and regional blood flow, blood pressure and metabolism. These changes are detectable after all major surgical procedures but are often more pronounced after cardiac surgery, probably because of blood exposure to artificial surfaces of the heart lung machine, temperature modulation (e.
