  1. 1. Endothelium-derived substances and regional hemodynamics in experimental hypertension

    Författare :Sven-Olof Granstam; Uppsala universitet; []
    Nyckelord :Medical sciences; nitric oxide; endothelin; hypertension; rats; SHR; hemodynamics; blood pressure; blood flow; acetylcholine; carvedilol; microsphere method; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The spontaneously hypertensive rat (SHR), a model for experimental hypertension, is considered to have similarities with essential hypertension in humans. Differences between SHR and normotensive Wistar Kyoto rats (WKY) in the vascular response to endothelial-derived substances such as nitric oxide (NO) have been intensively studied in vitro. LÄS MER

  2. 2. Mesentric hemodynamics and effects of angiotensin II during circulatory stress

    Författare :Mats Laesser; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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.

  3. 3. Aspects of pediatric hemodynamics. A study of young children undergoing corrective heart surgery

    Författare :Theódór Sigurdsson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac output; Heart surgery; Hemodynamics; Intracardiac shunt; Volume estimation; Young children;

    Sammanfattning : AbstractBackground: Assessing critically ill patients is demanding because their clinical signs are not always easy to interpret. This is particularly true for pediatric patients, due to their small size and robust circulatory compensatorymechanism. LÄS MER

  4. 4. Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain

    Författare :Guilherme Hilgert Elcadi; Albert Crenshaw; Mikael Forsman; Martin Fahlström; Svend Erik Mathiassen; Karen Sogaard; Karen Søgaard; Albert G Crenshaw; Högskolan i Gävle; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Near infrared spectroscopy; muscle oxygenation; hemodynamics; electromyography; extensor carpi radialis; trapezius; fysiologi; Physiology;

    Sammanfattning : The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. LÄS MER

  5. 5. Vacuum-Assisted Closure Therapy after Cardiac Surgery. Sternal Stability, Cost of Care, Learning Curve and Hemodynamic Outcome

    Författare :Arash Mokhtari; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health economics; Vacuum-assisted closure; Sternum; Mediastinitis; Deep sternal wound infection; Cardiac surgery; Wound healing; Hemodynamics; Wound closure;

    Sammanfattning : Deep sternal wound infection (DSWI) following cardiothoracic surgery is a rare but potentially life-threatening complication with high morbidity and mortality. DSWI is associated with a significant increase in the length of hospital stay and the cost of hospitalization. The socioeconomic impact of DSWI is considerable. LÄS MER
