Electrohysterography of labor contractions: propagation velocity and direction

Acta Obstetricia et Gynecologica Scandinavica, 2013
AbstractObjectiveElectrohysterographic assessment of the propagation velocity of uterine depolarization has been introduced as a promising predictor of preterm labor. Therefore, the objectives of this study were to characterize the uterine electrohysterographic signals during labor and to determine the propagation velocity and propagation direction of ...

Potential use of electrohysterography in obstetrics: a review article

The Journal of Maternal-Fetal & Neonatal Medicine, 2019
Monitoring the uterine contraction during pregnancy is necessary to monitor labor progress, fetal and maternal well-being, and uterine activity. The aim of this review was to evaluate the performance of electrohysterography and to analyze the nature of uterine contraction.

Validation of Electrohysterography for Uterine Peristalsis in Non-Pregnant Uteri

Journal of Minimally Invasive Gynecology, 2013
Uterine peristalsis in a non-pregnant uterus has proven to play a role in natural fertility. Uterine pathology can interfere with uterine peristalsis and subsequently hamper fertility. Currently used measurement tools, like trans vaginal ultrasound (TV-US) are time-consuming and inter-observer variability is of concern.

Electrohysterography may be integral to remifentanil Labor analgesia

The Journal of Maternal-Fetal & Neonatal Medicine, 2011
Electrohysterography can give the obstetric anesthesiologists a promising parameter to synchronize labor pain relief with remifentanil when patients do not want or cannot have labor epidurals due to their preferences against epidurals or anatomical difficulties in epidural placements.

Combining electrohysterography and heart rate data to detect labour

2017 IEEE EMBS International Conference on Biomedical & Health Informatics (BHI), 2017
In this paper we propose a method combining electrohysterography (EHG) and heart rate (HR) data to detect labour. Labour detection may be helpful in providing just in time care and avoiding unnecessary antenatal visits. Given specific changes in physiological data such as EHG and HR highlighted from previous literature in correspondence of uterine ...

Analysis of uterine activity in nonpregnant women by electrohysterography: A feasibility study

2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015
With an overall effectiveness below 30%, in vitro fertilization (IVF) is in urgent need for improvements, especially in view of the increasing trend in postponing childbirth in developed societies. Abnormal contraction of the uterus may underlie impaired fertility and unsuccessful IVF.

A positive association between postpartum electrohysterography parameters and blood loss after vaginal delivery: A prospective study [PDF]

Placenta
Introduction: The postpartum period can be complicated by hemorrhage, frequently caused by uterine atony. Electrohysterography, allowing continuous monitoring of uterine activity, may be a promising alternative for early detection of uterine atony, and ...
