  2. 6. Nitric oxide production by the intestinal mucosa during hypoperfusion

    Author : Johan Snygg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; nitric oxide synthase; intestinal epithelium; hemorrhagic shock; cardiac tamponade; septic shock; lower body negative pressure; splanchnic circulation; substrate; laser Doppler;

    Abstract : The present thesis is based on the concept that gastrointestinal blood hypoperfusion is a common phenomenon associated with critical illness. Furthermore, the development of the multiple organ dysfunction syndrome (MODS) is proposed to be initiated by gastrointestinal mucosal barrier dysfunction, allowing intestinal luminal contents to penetrate into the tissue and activate a systemic inflammatory response.

  4. 7. Levosimendan in early experimental sepsis: effects on the heart and hepatosplanchnic circulation

    Author : Doris Cunha Goncalves; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; septic shock; myocardial oxygen consumption; myocardial dysfunction; levosimendan; endotoxin; contractility; catecholamines; calcium sensitizer; cardiotonic agents; splanchnic perfusion;

    Abstract : Sepsis-related cardiovascular dysfunction associated with fluid-unresponsive tissue hypoperfusion might require inotropic treatment. This cardiovascular dysfunction seems to involve calcium desensitization and adrenergic unresponsiveness. READ MORE

  5. 8. On intestinal ischaemia after aortoiliac surgery : Epidemiological, clinical and experimental studies

    Author : Martin Björck; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Ischaemia; intestines; colon; ischaemic colitis; aorta-abdominal; aortic aneurysm-abdominal; aortic rupture; atherosclerosis; postoperative complications; cohort studies; case-control studies; clinical protocols; experimental design; incidence; risk factors; diagnosis; treatment outcome; intra-mucosal pH; pHi; swine; splanchnic circulation; haemodynamics; dobutamine; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : An important cause of death among patients undergoing surgery of the abdominal aorta is intestinal ischaemia. In the Swedish Vascular Registry 2930 aortoiliac operations were identified. The complication was studied in a combined cohort and case-control study, and multivariate analysis performed. The incidence of intestinal ischaemia was 2. READ MORE

  6. 9. Intestinal effects of lung recruitment maneuvers

    Author : Jonas Claesson; Ola Winsö; Stefan Lehtipalo; Conny Arnerlöv; Björn Biber; Göran Hedenstierna; Petter Aadahl; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute lung injury; oleic acid lung injury; ischemia; reperfusion injury; swine; mechanical ventilation; lung recruitment; splanchnic circulation; laser Doppler flowmetry; tissue oxygen tension; microdialysis; lactate; glycerol; Anaesthetics and intensive care; Anestesiologi och intensivvård; lungmedicin; Lung Medicine;

    Abstract : Background and aims: Lung recruitment maneuvers (brief episodes of high airway pressure) are a modern treatment alternative to achieve open lung conditions under mechanical ventilation of patients with acute lung injury. It is well known that positive pressure ventilation with high airway pressures cause negative circulatory effects, and that the effects on regional vascular beds can be even more pronounced than the systemic effects.

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

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

    Abstract : 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.
