  1. 21. Aortic Valve Replacement: The Influence of Prosthesis-Patient Mismatch for Left Ventricular Remodeling, Cardiac Function and Survival

    Författare :Shahab Nozohoor; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prosthesis-Patient Mismatch; Left Ventricular Remodeling; Survival; Aortic valve replacement;

    Sammanfattning : The best valve substitute for aortic valve replacement (AVR) in terms of hemodynamic performance, durability, incidence of complications, and survival remains the subject of much debate. It has been suggested that valve performance is influenced by the potentially modifiable variable prosthesis-patient mismatch (PPM). LÄS MER

  3. 22. Influence of tidal volume on pulmonary gas exchange during general anaesthesia

    Författare :Bruno Enekvist; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; sevoflurane; cardiac output; functional residual capacity; pulmonary gas exchange;

    Sammanfattning : Background and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP.

  4. 23. Aspects of pediatric hemodynamics. A study of young children undergoing corrective heart surgery

    Författare :Theódór Sigurdsson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac output; Heart surgery; Hemodynamics; Intracardiac shunt; Volume estimation; Young children;

    Sammanfattning : AbstractBackground: Assessing critically ill patients is demanding because their clinical signs are not always easy to interpret. This is particularly true for pediatric patients, due to their small size and robust circulatory compensatorymechanism. LÄS MER

  5. 24. 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; 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

  7. 25. Effects of Hemoglobin Normalization with Epoetin in Chronic Kidney Disease

    Författare :Hans Furuland; Björn Wikström; Torbjörn Linde; Peter Barany; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; Anemia; blood viscosity; cardiac output; chronic kidney disease; renal dialysis; dialysis adequacy; erythopoietin; heart rate variability; hemoglobin; hemorheology; hypertension; kidney transplantation; Kt V; left ventricular hypertrophy; Quality of Life; Invärtesmedicin; Internal medicine; Invärtesmedicin;

    Sammanfattning : Anemia is common in patients with chronic kidney disease (CDK), contributes to reduced Quality of Life (QoL) and is associated with cardiovascular disease, morbidity and mortality. Epoetin raises hemoglobin (Hb) and increases QoL and physical exercise capacity. LÄS MER
