  1. 1. Methodological aspects on microdialysis sampling and measurements

    Author : Pernilla Abrahamsson; Ola Winsö; Michael Haney; Anna-Maja Åberg; Urban Ungerstedt; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microdialysis; liver ischemia; heart ischemia; epicardium; liver parenchyma; CMA 600; metabolism; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anaesthesiology; anestesiologi;

    Abstract : Background:     The microdialysis (MD) technique is widely spread and used both experi­mentally and in clinical practice. The MD technique allows continuous collection of small molecules such as glucose, lactate, pyruvate and glycerol. Samples are often analysed using the CMA 600 analyser, an enzymatic and colorimetric analyser. READ MORE

  2. 2. Left ventricular function's relation to load, experimental studies in a porcine model

    Author : Roman A'roch; Michael Haney; Jan Poelaert; Lars-Åke Brodin; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart function; preload; afterload; contractility; myocardial tissue velocity; speckle tracking; Anaesthetics and intensive care; Anestesiologi och intensivvård; Cardiology; kardiologi;

    Abstract : Background: Loading conditions are recognized to influence ventricular function according to the Starling relationship for length/stretch and force.  Many modern echocardiographic parameters which have been announced as describing ventricular function and contractile status, may be confounded by uncontrolled and unmeasured load.

  3. 3. Cardiac effects of non-adrenergic inotropic drugs : clinical and experimental studies

    Author : Birger Axelsson; Michael Haney; Hans Tydén; Anil Gupta; Patrick Wouters; Sven-Erik Ricksten; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Milrinone; levosimendan; vein graft flow; myocardial ischemia; protection; inotropy; diastole; Anaesthesiology; anestesiologi;

    Abstract : Background: Myocardial failure and dysfunction is not uncommon during critical illness and following cardiac surgery. For optimal treatment, a better understanding of the effects of inotropic drugs is needed. In this thesis, two non-adrenergic mediated inotropes, milrinone and levosimendan were studied in different models of myocardial dysfunction. READ MORE

  4. 4. Accidental hypothermia and local cold injury : physiological and epidemiological studies on risk

    Author : Helge Brändström; Michael Haney; Urban Wiklund; Anders Eriksson; Karl-Axel Ängquist; Ola Winsö; Sigridur Kalman; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cold-related injuries; hypothermia; frostbite; cold adaptation; rewarming; autonomic nervous system; heart rate variability;

    Abstract : Background: (Papers I and II) The objectives were to first determine incidence and contributing factors to cold-related injuries in northern Sweden, both those that led to hospitalization and those that led to fatality.  (Papers III and IV) A further aim was to assess post-cooling hand-rewarming responses and effects of training in a cold environment, both on fingertip rewarming and on function of the autonomic nervous system, to evaluate if there was adaptation related to prolonged occupational cold exposure.

  5. 5. Detection of myocardial ischemia : clinical and experimental studies with focus on vectorcardiography, heart rate and perioperative conditions

    Author : Sören Häggmark; Ulf Näslund; Michael F Haney; Mårten Rosenqvist; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; myocardial ischemia; pacing; vectorcardiography; electrocardiography; heart rate; myocardial lactate; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; kardiologi; Cardiology;

    Abstract : Introduction. Multiple clinical methods for detecting myocardial ischemia are utilised in the hospital setting each day, but there is uncertainty about their diagnostic accuracy. READ MORE
