    Sammanfattning : In the 1930s and 1940s, less than one percent of the Swedish population were in higher education. By the beginning of 1990s this proportion had reached 2.4%. During the 1990s, however, a new economic current flowed in Swedish higher education. LÄS MER

  7. 30. Computerized vectorcardiography for on-line cardiac monitoring in non-cardiac surgery

    Författare :Per Gannedahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Anesthesia electrocardiography intraoperative monitonng laparoscopy myocardial ischemia vascularsurgery vectorcardiography. Stockholm 1997;

    Sammanfattning : Perioperative cardiac morbidity (PCM) remains high in risk groups such as peripheral vascular surgery. Preoperative assessment has not succeeded in identifying the individual patients most susceptible of PCM. Computerized vectorcardiography (VCG), a novel continuous on-line method for ischaemia monitoring was evaluated for perioperative use. LÄS MER
