  1. 1. Pressure sores : risk assessment and prevention

    Författare :Margareta Lindgren; Christina Lindholm; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The aims of this thesis were to study the prevalence, incidence, prevention and treatment of pressure sores, to further develop a risk assessment scale, and test the reliability and validity of this scale, to identify risk factors for pressure sore development, and to study skin blood flow in non-blanchable erythema areas as compared to undamaged skin.Criteria used for pressure sore assessment were persistent discoloration i.

  3. 2. Studies on sitting pressure and buttock microcirculation : aiming at developing an alarm in the prevention of pressure ulcers in patients with spinal cord injuries

    Författare :Johan Thorfinn; Disa Lidman; Folke Sjöberg; Henry Svensson; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Blood supply; Buttocks; Hyperemia; Ischemia; Laser-Doppler flowmetry; Microcirculation; Posture physiology; Pressure; Skin blood supply; Medicine; Medicin;

    Sammanfattning : Pressure ulcers in patients with spinal cord injuries are a major problem, the prevalence in this group being reported as high as 20 – 30 percent. Most pressure ulcers develop around the pelvic girdle, and the key-contributing factor in the development of pressure ulcers is ischaemia due to longstanding pressure. LÄS MER

  4. 3. The effect of mechanical ventilation on abdominal organs : Analysing the role of PEEP and perfusion

    Författare :Silvia Marchesi; Miklós Lipcsey; Anders Larsson; Göran Hedenstierna; Torbjörn Karlsson; Anders Oldner; Ragnvi Hagman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ARDS; sepsis; abdominal inflammation; edema; perfusion; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Background: The effect of mechanical ventilation on abdominal organs is not well understood and investigated yet. Previous studies, using an animal sepsis-like model, found an association between mechanical ventilation (MV) and abdominal edema and inflammation. LÄS MER

  5. 4. Secondary Insults in Neurointensive Care of Patients with Traumatic Brain Injury

    Författare :Kristin Elf; Per Enblad; Pelle Nilsson; Elisabeth Ronne-Engström; Bertil Romner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Traumatic brain injury; Neurointensive care; Monitoring; Secondary insults; Intracranial pressure; Cerebral perfusion pressure; Pressure reactivity; Temperature; Neural network; Outcome; Neurovetenskap; Neurology; Neurologi;

    Sammanfattning : Traumatic brain injury (TBI) is a major cause of death and disability. Intracranial secondary insults (e.g. intracranial haematoma, brain oedema) and systemic secondary insults (e. LÄS MER

  7. 5. Pulse-Synchronous Intramuscular Pressure Oscillations

    Författare :Andreas Nilsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; compartment syndrome; chronic anterior compartment syndrome; intramuscular pressure; pulse-synchronous oscillations in intramuscular pressure; ; intramuscular arterial pulsations; fiber-optic technique;

    Sammanfattning : Background Intramuscular pressure (IMP) is measured in studies of tissue nutrition and in the diagnosis of compartment syndromes. Patients with compartment syndromes have an elevated IMP due to increased volume in a muscle compartment. LÄS MER
