Comparison between Fetal Heart Rate Standard Parameters and Complexity Indexes for the Identification of Severe Intrauterine Growth Restriction

OBJECTIVES: The intrauterine growth restriction (IUGR) is a pathological state: the fetus is at risk of hypoxia and this condition is associated with increased perinatal morbidity and mortality...

Visual analysis of antepartum fetal heart rate tracings: inter- and intra-observer agreement and impact of knowledge of neonatal outcome

Objective: To evaluate the inter- and intra-observer agreement of visual analysis of fetal heart rate tracing and to evaluate the bias introduced by knowledge of perinatal outcome in this interpretation.

Methods: One hundred tracings were independently analyzed by four observers...

Keywords: Fetal heart rate, reliability, reproducibility

Fetal behavior analyzed by ultrasonic actocardiogram in cases with central nervous system lesions

Aims: This study examined whether analysis of fetal behavioral states by monitoring fetal heart rate and movement using an actocardiogram (ACG), could provide prognostic information related to fetal central nervous system (CNS) lesions.

Methods: The ACG simultaneously records fetal heart rate (FHR) and fetal movement bursts composed of spikes of ultrasonic Doppler signals...

Fetal scalp pH and ST analysis of the fetal ECG as an adjunct to cardiotocography to predict fetal acidosis in labor / A multi-center, case controlled study

Objective: To assess the relationship between scalp pH (FBS) and ST analysis in situations of acidosis with special emphasis on the timing of cardiotocography (CTG), FBS and ST changes during labor.

Study design: From a European Union multicenter study on clinical implementation of the STAN methodology, 911 cases were identified where a scalp-pH had been obtained...
