Fuzzy Prediction of Fetal Acidemia
Cardiotocography is the primary method for biophysical assessment of a fetal state. It is based mainly on the recording and analysis of fetal heart rate signal (FHR). Computer systems for fetal monitoring provide a quantitative description of FHR signals, however the effective methods for their qualitative assessment are still needed. The measurements of hydronium ions concentration (pH) in new...
متن کاملPrediction of fetal acidemia in placental abruption
BACKGROUND To determine the major predictive factors for fetal acidemia in placental abruption. METHODS A retrospective review of pregnancies with placental abruption was performed using a logistic regression model. Fetal acidemia was defined as a pH of less than 7.0 in umbilical artery. The severe abruption score, which was derived from a linear discriminant function, was calculated to deter...
متن کاملFetal acidemia and electronic fetal heart rate patterns: is there evidence of an association?
OBJECTIVE Despite the ubiquity of electronic fetal monitoring, the validity of the relationship between various fetal heart rate (FHR) patterns and fetal acidemia has not yet been established in a large unselected series of consecutive pregnancies. The aim of this study was to examine the published literature for evidence of such a relationship. METHODS Four hypotheses based on assumptions in...
متن کاملThe relationship between intrapartum amniotic fluid index, fetal distress and fetal acidemia.
Blood pressure ≥ 140/90 (OR = 1.3), age ≥ 35 years (OR = 1.2), pure African race (OR = 1.3) and group A blood (OR = 1.3), have all appeared to slightly increase the risk of recurrent miscarriage. As the study was very small, a larger study is needed to either confirm or refute any possible causal relationship. Age < 35 years (OR = 0.89), Arabic race (OR = 0.7), history of contraceptive use (OR ...
متن کاملPredicting fetal acidemia using umbilical venous cord gas parameters.
OBJECTIVE To assess the utility of umbilical cord venous blood gas measures for prediction of umbilical artery pH and base deficit acidemia. METHODS A retrospective cohort study was conducted of all singletons with valid paired arterial and venous cord gas samples delivered at our institution from January 2006 to March 2012. Fetal acidemia was defined primarily as cord arterial blood gas pH l...
