    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood gases; metabolic acidosis; umbilical cord; round-off; delayed sampling; validation;

    Sammanfattning : Acid-base status in umbilical cord blood is an objective measure of the fetus’ exposure to and ability to handle hypoxia. The objective of this thesis was to clarify some of the methodological pitfalls in interpreting umbilical cord blood gases and lactate values at birth. LÄS MER

    Sammanfattning : Umbilical cord blood acid-base status at birth gives an objective evaluation of the fetal exposure and response to hypoxia during labor. The objective of this thesis was to elucidate methodological issues associated with interpretation of cord blood gases. LÄS MER

  7. 5. Role of cerebral Blood Flow in Fetal Surveillance

    Författare :Riffat Cheema; Urogynekologi och reproduktionsfarmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : ABSTRACT In high-risk pregnancies the chronic hypoxemic fetus redistributes its circulation to maintain the blood supply to the vital organs: brain, heart and adrenals. The aims of the studies included in this thesis were: 1) to establish reference curves for fetal cerebral venous blood velocity in normal pregnancies; 2) to determine in high-risk pregnancies the frequency of abnormal Doppler in the cerebral veins and uterine, umbilical and middle cerebral arteries and the umbilical vein and ductus venosus with correlation with adverse perinatal outcome; 3) to analyze the correlation between brain sparing and redistribution of circulation and placental vascular impedance; 4) to evaluate the correlation between brain sparing and fetal umbilical cord blood gases at birth.
