  1. 1. Birth asphyxia : Fetal scalp blood sampling and risk factors for hypoxic ischemic encephalopathy

    Författare :Lena Liljeström; Maria Jonsson; Anna-Karin Wikström; Ulf Högberg; Andreas Herbst; Uppsala universitet; []
    Nyckelord :asphyxia; fetal scalp blood sampling; hypoxic ischemic encephalopathy; obstetric emergencies; operative deliveries for fetal distress; overweight; short stature; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Preventing birth asphyxia is a major challenge in delivery care. The aims of this thesis were to evaluate fetal scalp blood sampling (FBS) and explore risk factors for moderate to severe neonatal hypoxic ischemic encephalopathy (HIE). LÄS MER

  3. 2. Pathophysiology of intrauterine asphyxia

    Författare :Anna-Karin Welin; Göteborgs universitet; []
    Nyckelord :asphyxia; ECG; endotoxemia; fetal sheep; inflammation; melatonin; periventricular leukomalacia; preterm;

    Sammanfattning : Background: The premature infant is at increased risk of cerebral white matter damage, oftenreferred to as periventricular leucomalacia, PVL, which is associated with later developmentof cerebral palsy and cognitive impairment. The etiology of PVL remains unclear, but ischemia-reperfusion followed by generation of free radicals and intrauterine infections havebeen suggested to play an important role. LÄS MER

  4. 3. 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. 4. Fetal ECG waveform analysis for intrapartum monitoring

    Författare :Isis Amer-Wåhlin; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; Obstetrics; gynaecology; andrology; cerebral metabolism; microdialysis; implementation; fetal asphyxia; intrpartum monitoring; Fetal ECG; Cardiotocography; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : Waveform analysis of the fetal electrocardiogram has been studied since the early seventies from both physiological, signal processing and clinical aspects. It has been found to contain more useful information than the mere detection of RR-intervals (fetal heart rate), e.g. LÄS MER

  7. 5. Fractional moving blood volume in fetal organs estimated using power Doppler ultrasound

    Författare :Edgar Hernandez-Andrade; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; fetal adrenal gland; fetal lung; radionuclear microspheres; fetal lamb; perfusion; fetus; Power Doppler ultrasound; fractional moving blood volume;

    Sammanfattning : Power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. The aim of the present study was to develop a standardized method for quantification of the PDU signals recorded from a specific region of interest (ROI) within fetal organs. LÄS MER
