  1. 21. Advanced cranial navigation

    Författare :Simon Skyrman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neurosurgery is performed with extremely low margins of error. Surgical inaccuracy may have disastrous consequences. The overall aim of this thesis was to improve accuracy in cranial neurosurgical procedures by the application of new technical aids. LÄS MER

  3. 22. Experimental cardiopulmonary cerebral resuscitation : A study of cerebral perfusion with special reference to the postresuscitation disturbances

    Författare :Ala Nozari; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac arrest; cardiopulmonary resuscitation; cerebral blood flow; post-resuscitation period; epinephrine; vasopressin; aortic occlusion; isoprostane; Kirurgi; Surgery; Kirurgi; Anestesiologi; Anaesthesiology;

    Sammanfattning : Ischemic neuronal injury continues to be a major delimiting factor in achieving successful clinical outcomesafter resuscitation from cardiac arrest. In this thesis, a pig model of cardiopulmonary resuscitation (CPR) wasused to address the effects of different interventions on cerebral blood flow and oxygenation during CPR and theinitial postresuscitation period.

  4. 23. Isolation and characterization of regulatory peptides and bioactive compounds

    Författare :Åke Norberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Isolation of peptides and other bioactive compounds is an important and often necessary step to get the total information about their structures. This is demonstrated by a number of different characterizations in this thesis. LÄS MER

  5. 24. Cerebral perfusion during cardiopulmonary bypass with special reference to blood flow

    Författare :Thomas Tovedal; Fredrik Lennmyr; Stefan Thelin; Dan Lindblom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cardiopulmonary bypass (CPB) is an important method that enables open heart surgery. There is a risk of neurological complications, and efforts to minimize those include optimization of the cerebral perfusion during CPB. LÄS MER

  7. 25. Laser doppler tissue flowmetry : fiberoptic methods in microvascular research

    Författare :Göran Salerud; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Laser Doppler flowmetry (LDF) constitutes a method for measuring the flux of blood cells in the microcirculatory bed. Photons are scattered in the moving blood cells, where they undergo a frequency shift according to the Doppler principle. LÄS MER
