Signal ambiguity resulting in unexpected outcome with external fetal heart rate monitoring.
نویسندگان
چکیده
We report cases of unexpected adverse fetal outcome from monitored labors in which the fetal heart rate tracing was interpreted as reassuring. In these cases, portions from another signal source, usually maternal, were imperceptibly substituted into the fetal tracing in a way that masked the evidence of fetal compromise.

Intrapartum heart rate ambiguity: a comparison of cardiotocogram and abdominal fetal electrocardiogram with maternal electrocardiogram.
OBJECTIVE/AIMS To investigate the presence of signal ambiguity of intrapartum fetal heart rate (FHR) monitoring during delivery by comparing simultaneous cardiotocogram (CTG), abdominal fetal electrocardiogram (ECG) with continuous maternal ECG. METHODS A total of 144 simultaneous CTG (Corometrics 250 series), abdominal fetal ECG (Monica -AN24™) and maternal ECG (Monica AN24™) recordings were...

Despite its recognized limitations, fetal heart rate monitoring is a mainstay of intrapartum care. Although the basic technology in standard electronic fetal monitors has changed little in recent decades, clinical behavior in response to heart rate monitoring has changed considerably. In addition to clearly defined nomenclature and clinical guidelines, there is an increased awareness that envir...
متن کاملInfluence of Input Data Modification of Neural Networks Applied to the Fetal Outcome Classification
Cardiotocographic (CTG) fetal monitoring based on automated analysis of the fetal heart rate signal is widely used for fetal assessment. The high efficiency in diagnosis of cases with no fetal risk makes it a valuable screening method. However, the conclusion generation system is still needed to improve the fetal outcome prediction. Classification of the CTG records by means of neural networks ...
متن کاملFetal heart rate pattern notification guidelines and suggested management algorithm for intrapartum electronic fetal heart rate monitoring.
CONTEXT Numerous randomized controlled trials have demonstrated limited efficacy of intrapartum fetal heart rate monitoring in improving fetal outcome. A potential reason is the wide variability in clinical decision making seen with its use. Standardizing management of variant intrapartum fetal heart rate tracings may reduce this variability and lead to improvement in fetal outcome. OBJECTIVE...
متن کاملFetal heart rate monitoring of short term variation (STV): a methodological observational study.
BACKGROUND Cardiotocography (CTG) has high sensitivity, but less specificity in detection of fetal hypoxia. There is need for adjunctive methods easy to apply during labor. Low fetal heart rate short term variation (STV) is predictive for hypoxia during the antenatal period. The objectives of our study were to methodologically evaluate monitoring of STV during labor and to compare two different...
