  1. 16. Physiological aspects on intracardiac blood flow

    Författare :Per Arvidsson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; 4D flow; physiology; cardiac development; kinetic energy; hemodynamic force; vortex ring formation;

    Sammanfattning : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.

  3. 17. Evaluation of various strategies to improve outcome after out-of-hospital cardiac arrest with particular focus on mechanical chest compressions

    Författare :Christer Axelsson; Högskolan i Borås; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; out-of-hospital cardiac arrest; mechanical chest compressions; end tidal carbon dioxide; passive leg raising; dispatch code; randomised clinical trial; out-of-hospital cardiac arrest; mechanical chest compressions; end tidal carbon dioxide; passive leg raising; dispatch code; randomised clinical trial;

    Sammanfattning : Cardiopulmonary resuscitation (CPR) skills vary among health care professionals. A previous study revealed that chest compressions were only performed half the time in out-of-hospital cardiac arrest (OHCA). Field conditions and fatigue could be possible explanations. LÄS MER

  5. 19. Early childhood thymectomy - impact on immune function

    Författare :Judith Gudmundsdottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Immunologi; Thymus; Pediatric cardiac surgery; Congenital heart defect;

    Sammanfattning : Introduction: The thymus is the site of T cell maturation. Children born with a congenital heart defect often endure surgery early in life, and during surgery their thymus is routinely removed, as it blocks the surgeons access to the heart. LÄS MER

  7. 20. Cerebrovascular accidents associated with aortic manipulation during cardiac surgery

    Författare :Patrik Boivie; Gunnar Engström; Magnus Hansson; Henrik Ahn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic atherosclerosis; aortic cannulation; aortic cross-clamp; cardiac surgery; cerebral protection; cerebrovascular accidents; epiaortic ultrasound; intra-aortic filter; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Sammanfattning : Background: Despite the successful development in cardiac surgery, cerebrovascular accidents (CVA) remain a devastating complication. Aortic atherosclerosis has been identified as a major risk factor for CVA. LÄS MER
