  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.

  2. 2. Influence of total pressure on complete oxidation of methane over Pd/Al2O3 catalysts

    Författare :Carl-Robert Florén; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Pd Al2O3; methane oxidation; multiscale flow-reactor model; total pressure;

    Sammanfattning : Natural gas and biogas, which have methane as their main component, are interesting choices of fuel to reduce the anthropogenic emissions of greenhouse gases. However, as methane is a greenhouse gas, uncombusted methane should be removed from the combustion gases. Emission control catalysts can preferably be used to completely oxidise methane. LÄS MER

  3. 3. Negative Pressure Wound Therapy - Effects on Sternotomy Wounds and the Intrathoracic Organs

    Författare :Christian Torbrand; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NPWT; negative pressure; vacuum-assisted closure; sternotomy wounds; deep sternal wound infection; mediastinitis; thoracic surgery; pressure transduction; neurohormones; neuropeptides; total heart volume variation; cardiac output; wound contraction; macrodeformation;

    Sammanfattning : Negative pressure wound therapy (NPWT) has been widely adopted for the treatment of deep sternal wound infections due to its excellent clinical outcome. However, the mechanisms of action and effects on hemodynamics have not been thoroughly elucidated. LÄS MER

  4. 4. Myocardial Topical Negative Pressure

    Författare :Sandra Lindstedt Ingemansson; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary blood flow; microvascular blood flow; topical negative pressure TNP ;

    Sammanfattning : The aim of this research was to find out if it is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. LÄS MER

  5. 5. Greater trochanteric pain after total hip arthroplasty : incidence, clinical outcome, associated factors, tenderness evaluation with algometer and a new surgical treatment

    Författare :Arkan Sam Sayed-Noor; Lars Weidenhielm; Umeå universitet; []
    Nyckelord :greater trochanteric pain; total hip arthroplasty; leg length discrepancy; algometer; pressure-pain threshold; ilio-tibial band; lengthening; Orthopaedics; ortopedi;

    Sammanfattning : Greater trochanteric pain (GTP) is a regional pain syndrome characterized by lateral hip pain and tenderness. Its incidence after total hip arthroplasty (THA) is variable. LÄS MER
