1. Fetal surveillance and outcome in postterm pregnancy
Sammanfattning : To minimize the risk of short-term and long-term morbidity and mortality among children born postterm, studies were performed to evaluate the fetal surveillance program. (1) Male-fetus pregnancies were at an increased risk... LÄS MER
2. Acid-base values in umbilical cord blood at birth
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
3. Spontaneous abortion : risk factors and measurement of exposures
Sammanfattning : The overall objectives of this thesis were to increase the understanding of the etiology of spontaneous abortion and repeated spontaneous abortion, and to evaluate possibilities of exposure assessment during pregnancy. Data from a Swedish population-based case-control study of spontaneous abortion, performed in Uppsala County 1996-98, formed the base for the three first studies of the thesis. LÄS MER
4. Pitfalls in Interpreting Umbilical Cord Blood Gases and Lactate at Birth
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
5. Acidaemia at Birth: Risk factors, diagnosis and prognosis, with special reference to maternal fever in labour
Sammanfattning : Acidaemia at birth is a result of an impaired intrauterine gas exchange. Between 1988 and 1996, acid-base balance in cord artery blood pH was assessed in 23 016 of 27 064 newborns (85%). Obstetric risk factors for acidaemia (cord artery pH < 7.05) were identified in a case-control study. LÄS MER
