2. 1. Ultrasound as predictor of perinatal outcome

   Author : Gisela Ghosh; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Doppler; Ultrasound; fetus; amniotic fluid index; nuchal cord; uterine artery; umbilical vein; fetal growth restriction; umbilical artery; pulsation; pregnancy;

   Abstract : The aim of the work described in this thesis was to evaluate the value of ultrasound examinations of the amniotic fluid, umbilical cord and blood flow velocity waveform of the fetal and placental vessels as predictors of the perinatal outcome. In the first study, the amniotic fluid index (AFI) measured on admission to the labour ward was evaluated in low-risk pregnancies. READ MORE

4. 2. Studies on Prostanoid Production in the Umbilicoplacental Circulation

   Author : Pia Saldeen; Malmö Reproduktionsmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; Obstetrics; Umbilical; Thromboxane; Pulsatility Index; Prostacyclin; Pregnancy; Placenta; Peroxidation; Growth restriction; Endoperoxides; Endothelium; Doppler; Diabetes; sexualitet; reproduktion; andrologi; gynekologi; andrology; reproduction; sexuality; Obstetrik;

   Abstract : The fetoplacental circulation is a low pressure system with a high vascular prostacyclin to thromboxane (Pc/Tx)synthesis ratio. In intrauterin growth restriction (IUGR) and diabetes the prostanoid balance may be altered. READ MORE

5. 3. Dynamic Fetal and Placental Circulatory Changes during Uterine Contractions

   Author : Hui Li; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexualitet; reproduktion; andrologi; gynekologi; Obstetrik; sexuality; reproduction; andrology; gynaecology; Obstetrics; Venous; Uterine; Umbilical; Resistance; Pregnancy; Oxytocin; Labor; IUGR; Flow; Doppler; Contraction; Brain-sparing; Cerebral;

   Abstract : The best mode of delivery for fetuses with intrauterine growth restriction (IUGR) and umbilical artery (UA) blood flow changes is not well elucidated. Uterine artery, fetal UA, middle cerebral artery (MCA), and venous blood flow changes during uterine contractions during an oxytocin challenge test (OCT) have not been observed systemically.

6. 4. Pitfalls in Interpreting Umbilical Cord Blood Gases and Lactate at Birth

   Author : Parisa Mokarami; Urogynekologi och reproduktionsfarmakologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood gases; metabolic acidosis; umbilical cord; round-off; delayed sampling; validation;

   Abstract : 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. READ MORE

7. 5. Acid-base values in umbilical cord blood at birth

   Author : Nana Wiberg; Urogynekologi och reproduktionsfarmakologi; []
   Keywords : Apgar score; Acidosis; Base deficit; Blood gases; Gestational age; Hidden acidosis; lactate; Umbilical cord blood;

   Abstract : 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. READ MORE
