Abstract
Background: Most conventional cardiotocographs (CTG) work on the ultrasound principle and are heavily used by doctors to measure fetal heart rate (FHR) and uterine contractions (UCs). Despite their widespread usage, they have limitations with accessibility, portability and ease of use. Electrocardiogram (ECG) which relies on electrical signals gives a far superior signal during labor, yet it is ineffective to measure FHR unless an invasive scalp electrode is inserted. Noninvasive fECGs (ni-fECG) are still subject to constant research and validation. The ni-fECG device is a novel, ECG and electromyography (EMG)-based medical device that measures FHR, UC and maternal heart rate (MHR) continuously. It is portable, wearable and easy to use. This study aimed to assess the accuracy of the ni-fECG device with the conventional ultrasound-based CTG.
Methods: A prospective observational study was conducted on 282 pregnant women. The inclusion criteria included women ≥ 28 weeks of gestational age with singleton pregnancy and cephalic presentation. The procedure used in both the devices to monitor FHR and UC was explained to the participants. Data analysis was done using Python Jupyter Notebook.
Results: The accuracy for baseline heart rate, FHR and UC was found to be 97.37%, 91.3% and 70.27%, respectively. BMI and maternal age did not have a significant impact on the comparative accuracy.
Conclusion: With further improvements in UC accuracy the ni-fECG device could be a viable alternative to CTGs.
期刊介绍:
Journal of Obstetrics and Gynecology of India (JOGI) is the official journal of the Federation of Obstetrics and Gynecology Societies of India (FOGSI). This is a peer- reviewed journal and features articles pertaining to the field of obstetrics and gynecology. The Journal is published six times a year on a bimonthly basis. Articles contributed by clinicians involved in patient care and research, and basic science researchers are considered. It publishes clinical and basic research of all aspects of obstetrics and gynecology, community obstetrics and family welfare and subspecialty subjects including gynecological endoscopy, infertility, oncology and ultrasonography, provided they have scientific merit and represent an important advance in knowledge. The journal believes in diversity and welcomes and encourages relevant contributions from world over. The types of articles published are: · Original Article· Case Report · Instrumentation and Techniques · Short Commentary · Correspondence (Letter to the Editor) · Pictorial Essay
