  1. 1. Retained Placenta and Postpartum Haemorrhage

    Författare :Johanna Belachew; Ove Axelsson; Karin Eurenius; Ajlana Mulic-Lutvica; Kjell Å Salvesen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postpartum haemorrhage; retained placenta; secondary postpartum haemorrhage; retained placental tissue; threedimensional ultrasound; previous caesarean section; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : The aim was to explore the possibility to diagnose retained placental tissue and other placental complications with 3D ultrasound and to investigate the impact of previous caesarean section on placentation in forthcoming pregnancies.3D ultrasound was used to measure the volumes of the uterine body and cavity in 50 women with uncomplicated deliveries throughout the postpartum period.

  3. 2. Nitric oxide donors in labor management

    Författare :Maria Bullarbo; Göteborgs universitet; []
    Nyckelord :cervical ripening; labor induction; nitric oxide donor; retained placenta;

    Sammanfattning : ABSTRACT Nitric oxide donors in labor management Maria Bullarbo Department of Obstetrics and Gynecology Institute of Clinical Sciences Background: Nitric oxide (NO), a free radical with ultra-short half-life synthesized from L- arginine by the enzyme nitric oxide synthase (NOS), is in the human involved in many physiological and pathophysiological processes, including different reproductive processes. During pregnancy NO is produced endogenously in the human uterine cervix and placenta. LÄS MER

  4. 3. Characterizing retained placenta : epidemiology and pathophysiology of a critical obstetric disorder

    Författare :Margit Endler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Retained placenta is associated with severe postpartum hemorrhage but its etiology and pathophysiology are largely unknown. Certain studies have suggested that retained placenta is associated to defective placentation disorders- pregnancy disorders with an initial defective placentation resulting in increased oxidative stress.

  5. 4. Postpartum Ultrasound

    Författare :Ajlana Mulic-Lutvica; Ove Axelsson; Karin Eurenius; Torvid Kiserud; Uppsala universitet; []
    Nyckelord :Medicine; Postpartum ultrasound; Uterine artery Doppler; Retained placental tissue; Secondary postpartum hemorrhage; Puerperium; Endometritis postpartum; Cesarean section; Medicin;

    Sammanfattning : This study was undertaken to investigate the involutional changes of the uterus and uterine cavity by ultrasound (US), gray-scale and Doppler, after normal delivery, and to compare with the corresponding findings from women with puerperal complications, particularly retained placental tissue (RPT). The overall design was exploratory and prospective, with the use of descriptive statistics for analysis. LÄS MER

  7. 5. Immune regulation at the foetal-maternal interface; implications for healthy and complicated pregnancies

    Författare :Robert Lindau; Jan Ernerudh; Maria Jenmalm; Kristina Nilsson-Ekdahl; Petra Arck; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : For a successful pregnancy, the maternal immune system must acquire tolerance towards the paternal antigens present in the semi-allogeneic foetus. This tolerance is mainly established locally at the foetal-maternal interface, where foetally-derived trophoblasts invade the maternal endometrium (called decidua during pregnancy) and come in close proximity to maternal immune cells.
