16. Cerebral Perfusion and Metabolism during Experimental Extracorporeal Circulation
Sammanfattning : 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.

17. Isolated regional perfusion for metastases of malignant melanoma - Clinical and experimental studies
Sammanfattning : Background: Isolated regional perfusion is a treatment option mainly for localized metastatic disease. The principle idea is to surgically isolate a region of the body and connect the circulation to a heart-lung machine. A high concentration of a chemotherapeutic agent is then delivered to the tumour, while systemic toxicity is avoided. LÄS MER
18. Ventilation/Perfusion Matching and its Effect on Volatile Pharmacokinetics
Sammanfattning : The mismatching of alveolar ventilation and perfusion (VA/Q) is the major determinant of impaired gas exchange. The gold standard for analyzing VA/Q distribution is the multiple inert gas elimination technique (MIGET), conventionally based on gas chromatography (GC), and, although simple in principle, a technically demanding procedure limiting its use.

19. Detection of Myocardial Ischemia using Real-Time Myocardial Contrast Echocardiography
Sammanfattning : Diagnostisering av syrebrist i hjärtmuskeln med hjälp av kontrastförstärkt ultraljudsundersökning av hjärtmuskelns genomblödning. Ultraljudsundersökning av hjärtat (ekokardiografi) används mycket inom hjärtsjukvården idag, oftast för att utreda hjärtats och hjärtklaffarnas anatomi och funktion. LÄS MER
20. The effect of mechanical ventilation on the abdominal organs
Sammanfattning : During mechanical ventilation (MV), the interplay between abdomen and thorax has been studied unilaterally focusing on the effect that an increased abdominal pressure would have on the thorax. Only a small cluster of studies offered a different perspective showing a lower inflammation and a better lymphatic clearance of edema in abdominal organs when spontaneous breathing was applied compared to MV.
