1. Nitric oxide donors in labor management
Sammanfattning : ABSTRACT Nitric oxide donors in labor management Maria Bullarbo Department of Obstetrics and Gynecology Institute of Clinical Sciences Background: Nitric oxide (NO), a free radical with ultra-short half-life synthesized from L- arginine by the enzyme nitric oxide synthase (NOS), is in the human involved in many physiological and pathophysiological processes, including different reproductive processes. During pregnancy NO is produced endogenously in the human uterine cervix and placenta. LÄS MER
2. Factors of importance for labor induction
Sammanfattning : Background: What initiates the onset of labor is still not clarified, and it is debated whether expectant or active management is the best for the woman and the fetus. Active management means induction of labor (IOL) which is a very common obstetric intervention and is used in several situations. LÄS MER
3. Hyperglycemia in pregnancy : diagnostics and duration of labor
Sammanfattning : Objectives: The overall aim of this thesis was to evaluate the impact of maternal hyperglycemia in pregnancy on the duration of active labor, to evaluate indications for cesarean section and further, to examine cut-offs for gestational diabetes mellitus diagnosis based on capillary sampling.Material and methods: Study I was a cross-sectional study on diagnostic accuracy performed at an antenatal care clinic at the University Hospital in Linköping, Sweden.

4. Three - dimensional ultrasound studies of the cervix in pregnancy
Sammanfattning : The aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representative normal findings of the cervix assessed by 3D ultrasound during pregnancy (studies II, III) and the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy.

5. Management of late term pregnancy
Sammanfattning : Background: The optimal time point to intervene and induce labour in women with a low-risk pregnancy, in order to decrease perinatal adverse outcome, is up for debate. Some advocate for induction of labour (IOL) at 41 gestational weeks (GW) and others for expectant management (EM) until 42 GW. LÄS MER
