    Sammanfattning : Under åren 1977–89 bedrev arkeologiska institutionen vid Umeå universitet en forskningsundersökning av en boplats från äldre järnålder på Genesmon i Själevad socken, norra Ångermanland. Under åren 1991–99 rekonstruerades delar av gården i Gene fornby, ett hundratal meter därifrån. LÄS MER

  4. 4. Operating Room Efficiency and Postoperative Recovery after Major Abdominal Surgery : The Surgical Team’s Efficiency and the Early Postoperative Recovery of Patients with Peritoneal Carcinomatosis

    Författare :Erebouni Arakelian; Haile Mahteme; Lena Gunningberg; Jan Larsson; Karin Norlén; Gun Nordström; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; efficiency; operating room; postoperative recovery; peritoneal carcinomatos; cytoreductive surgery; HIPEC;

    Sammanfattning : In selected patients, surgical treatments such as cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have enabled curative treatment options for previously incurable diseases, such as peritoneal carcinomatosis (PC). The introduction of resource demanding surgery could affect the work process, efficiency, and productivity within a surgical department and factors influencing patient postoperative recovery processes may have an impact on the efficiency of patient care after major surgery.
