  1. 1. Intracranial Compliance and Secondary Brain Damage. Experimental and Clinical Studies in Traumatic Head Injury

    Författare :Konstantin Salci; Per Enblad; Pelle Nilsson; Peter Hutchinsson; Uppsala universitet; []
    Nyckelord :Neurosciences; Traumatic brain injury; Intracranial compliance; Secondary insults; Microdialysis; Neurointensive care; Neurovetenskap;

    Sammanfattning : Traumatic brain injury (TBI) renders the brain more vulnerable to secondary insults. The increased vulnerability can probably be explained by a combination of disturbances in hemodynamics, metabolism and craniospinal dynamics. Reduced ability to compensate for added intracranial volume, i.e. LÄS MER

  3. 2. Experimental skin flaps and nitric oxide

    Författare :Örjan Gribbe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Surgical flaps; nitric oxide; ischemia; reperfusion; nitrite; laser Doppler; transit-time ultrasound flowmetry; electron microscopy; NO donors; NOS inhibitors;

    Sammanfattning : Surgical flaps are used in plastic surgery to reconstruct tissue defects due to trauma or cancer removal. Occasionally flaps are subjected to ischemia and reperfusion injury leading to flap failure. LÄS MER

  4. 3. Surgical trauma, inflammation and tissue injury

    Författare :Leif Törkvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Activated partial thromboplastin time; blood flow; blood pressure; CD18; calcitonin gene-related peptide; dalteparin; glucocorticoids; heparin; intravital microscopy; leukotrienes; myeloperoxidase; neutrophils; stress; surgical flaps; rat;

    Sammanfattning : Surgical tissue trauma is a strong stimulus for local inflammation, including leukocyte recruitment. While such a response may be of importance for the defense against microorganisms, it is also clear that inflammation may contribute to further tissue injury. LÄS MER

  7. 5. Perfusion Monitoring During Oculoplastic Reconstructive Surgery - Opportunities for Optimization of Surgical Techniques

    Författare :Khashayar Memarzadeh; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Existing oculoplastic reconstructive surgical techniques are based on empirical knowledge and were established long before perfusion monitoring was possible. It is believed that an avascular graft should always be placed on a vascular bed or flap and also that the viable length of a flap depends on the width of its pedicle. LÄS MER
