  1. 1. 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

  3. 2. Lactate as an early marker of intrapartum fetal hypoxia

    Författare :Malin Holzmann; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cardiotocography;

    Sammanfattning : Background: Cardiotocography (CTG) is the main method for intrapartum fetal surveillance in many countries. The method has a high sensitivity, but a poor specificity, which leads to an increased rate of interventions compared with auscultation. LÄS MER

  4. 3. ST analysis of the fetal ECG as an adjunct to fetal heart rate monitoring in labour-a clinical validation

    Författare :Håkan Noren; Göteborgs universitet; []
    Nyckelord :fetal ECG; ST analysis; electronic fetal monitoring; cardiotocography; fetal blood sampling; metabolic acidosis;

    Sammanfattning : The ability to make an accurate assessment of fetal well-being during labour is a great challenge. Animal and human studies have shown that fetal hypoxemia during labour can alter the shape of the fetal electrocardiogram (FECG) waveform, notable elevation of the T-wave and depression of the ST segment.

  7. 5. Hypoglycaemia in pregnancy : hypoglycaemic clamp studies during and after pregnancy in women with IDDM

    Författare :Anders Björklund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adrenaline; cardiotocography; cognitive function; Doppler; fetal; fetal monitoring; growth hormone; hormonal counterregulation; hypoglycaemia; insulin; insulin-dependent diabetes mellitus; metabolic clearance rate; placenta; pregnancy; subjective symptoms;

    Sammanfattning : Problem: In pregnant women with IDDM a strict insulin regimen is generally instituted, which permits the possibility of a normal fetal outcome. This, however, increases the risk of hypoglycaemia, and a high prevalence of severe hypoglycaemia has been reported during pregnancy in these women. LÄS MER
