  1. 11. Fetal echo doppler for early detection of congenital heart block

    Författare :Gunnar Bergman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Fetal echo Doppler methods detecting prolonged atrioventricular (AV) time intervals, a mechanical PR interval corresponding to the electrical PR interval in ECG, have been proposed for surveillance of pregnancies at risk of complete congenital heart block (CCHB). The aim of this thesis was; to validate these Doppler methods by comparing AV time intervals from left ventricular inflow (MV), inflow and aortic outflow (MV-Ao) and superior vena cava and aortic flow (SVC-Ao) with ECG in newborns (Paper I); to investigate the significance of mechanical components in AV time prolongation (Paper II); to evaluate the diagnostic precision in a target population (Paper III) and to verify childhood outcome of fetuses, exposed to maternal anti- SSA/Ro antibodies (SSA),(Paper IV).

  2. 12. Fetal hematopoietic cells in early gestation : aspects in view of fetal transplantation

    Författare :Sverker Ek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Fetal stem cells; fetal liver; fetal hematopoiesis; immunological ontogeny; fetal transplantation; cytokines; CD34 enrichment;

    Sammanfattning : The fetus as a patient is a challenge. There are opportunities for early, sometimes life-saving procedures or there may be advantages in prenatal rather than postnatal intervention. This is the case in fetal hematopoietic cell (FHC) transplantation where conditions caused by a defect in blood cell formation may be life-threatening to the fetus. LÄS MER

  3. 13. Maternal diabetes during pregnancy – obstetrical considerations and long term effects

    Författare :Andrea Stuart; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Maternal diabetes mellitus (DM) during pregnancy has detrimental health impacts on both the mother and fetus, and include increased risks of cardiac malformations, cesarean section (CS), and asphyxia. The aim of the thesis was to investigate short and long term cardiac effects after fetal exposure to DM, investigate the ability of a 5 minute Apgar score as a marker for obstetrical care, investigate the association between mode of delivery in diabetic pregnancies and a low 5 minute Apgar score, and to investigate the association between offspring birth weight and maternal risk of future DM.

  4. 14. Fetal reactivity assessment during intrapartum stress by analysis of the fetal ECG signal

    Författare :Sofia Blad; Göteborgs universitet; []
    Nyckelord :FHR variability; fetal ECG; Asphyxia; Intrauterine infection; Residual method; STAN;

    Sammanfattning : Fetal responses to the stress of labour and delivery are constituted by a combination of changes in neuronal, hormonal and organ based reactions. The aim of electronic fetal monitoring is to identify fetuses at risk of hypoxia during birth, thus enabling timely intervention to avoid an adverse outcome. LÄS MER

  5. 15. Fetal growth in India : studies on antenatal prediction of low birthweight and some factors that determine birthweight

    Författare :Matthews Mathai; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Fetal growth; birthweight; light for gestational age; Indian; fundal height; fetal biometry; ethnic; smoking; genital infection.;

    Sammanfattning : Objectives: To develop standards for assessment of fetal growth in India and to study some factors that determine birthweight. Methods: Data from 250 normal pregnancies were used to construct graphs of fundal height, abdominal girth and the ratio of fundal height to abdominal length. LÄS MER
