1. 1. Methodological aspects on microdialysis sampling and measurements

   Författare :Pernilla Abrahamsson; Ola Winsö; Michael Haney; Anna-Maja Åberg; Urban Ungerstedt; Umeå universitet; []
   Nyckelord :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; anestesiologi; Anaesthesiology;

   Sammanfattning : 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. LÄS MER

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

   Författare :Roman A'roch; Michael Haney; Jan Poelaert; Lars-Åke Brodin; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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.

7. 5. Prehospital medical management in Swedish road tunnel incidents

   Författare :Johan Hylander; Anton Westman; Britt-Inger Saveman; Lina Gyllencreutz; Michael Haney; Stephen Sollid; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Road tunnel; incident management; disaster medicine; emergency medical services; e-learning; education; ambulance commander;

   Sammanfattning : Background: The complexity of modern road tunnel systems may delay an efficient rescue effort. Capable decision-making is needed to limit time to care. The Swedish ambulance commander, responsible for the on-scene ambulance personnel, may lack education and experience from managing road tunnel incidents. LÄS MER
