Electronic fetal monitoring: a brief summary of its development, problems and prospects

Autor: Chester B. Martin

Publikováno v: European Journal of Obstetrics & Gynecology and Reproductive Biology. 78:133-140

Electronic fetal monitoring (EFM) was introduced into clinical practice 30 years ago and spread very rapidly in most developed countries. The early optimism that EFM would lead to a marked reduction in fetal neurological injury has not been realized;

Accuracy of maternal perception of preterm uterine activity

Autor: Niki K. Bergauer, Gary Stanziano, Charles R.B. Beckmann, Chester B. Martin, Claudia Anderson Beckmann

Publikováno v: American Journal of Obstetrics and Gynecology. 174:672-675

OBJECTIVE: Our purpose was to compare the accuracy of maternal perception of preterm uterine activity by self-palpation versus home uterine activity monitoring. STUDY DESIGN: A total of 72,962 uterine activity records of 778 women receiving home uter

Spatiotemporal properties of the fetal magnetocardiogram

Autor: Minghong Wang, Ronald T. Wakai, Chester B. Martin

Publikováno v: American Journal of Obstetrics and Gynecology. 170:770-776

OBJECTIVE: Our purpose was to investigate the spatiotemporal properties of the fetal magnetocardiogram. STUDY DESIGN: Fetal magnetocardiogram maps were measured for the first time in 20 subjects from 22 to 39 weeks' gestation. Waveform and topographi

Spectral analysis of antepartum fetal heart rate variability from fetal magnetocardiogram recordings

Autor: Stephen L. Pedron, Minghong Wang, Chester B. Martin, Ronald T. Wakai, Deborah L. Reid

Publikováno v: Early Human Development. 35:15-24

Fetal heart rate variability was derived from fetal magnetocardiogram recordings in ten subjects at gestation ages 32–38 weeks. Maternal interference was negligible and R-wave detection was highly reliable. Oscillations suggestive of respiratory si

Characterization of Uterine Contractures and Demonstration of Placental Vasodilation in the Mid-Gestation Albino Guinea Pig

Autor: David L. Darr, Terrance M. Phernetton, Tamara Verhalen, Lori Jarecki, Chester B. Martin, John H.G. Rankin, Deborah L. Reid

Publikováno v: Journal of Maternal-Fetal and Neonatal Medicine. 2:111-116

Twenty-five mid-gestation guinea pigs were studied to determine the nature of spontaneous uterine contractures and elucidate the temporal relationship between blood flow and contractile activity. In the first protocol, 15 mid-gestation guinea pigs wi

Effect of Oxymorphone Hydrochloride on Ovine Fetal Heart Rate Variability

Autor: Terrance M. Phernetton, Deborah L. Reid, Chester B. Martin, Keith M. Williams, John H.G. Rankin

Publikováno v: Journal of Maternal-Fetal and Neonatal Medicine. 1:258-262

In order to determine the effect of the narcotic analgesic oxymorphone hydrochloride (Numorphan, DuPont) on fetal heart rate (FHR) variability, mathematical indices of short-term and long-term FHR variability were determined continuously from R–R i

Normal fetal physiology and behavior, and adaptive responses with hypoxemia

Autor: Chester B. Martin

Publikováno v: Seminars in perinatology. 32(4)

The principal objective of antenatal testing is to detect fetal hypoxia before the fetus has suffered lasting harm. This article summarizes some of the mechanisms by which fetal oxygen consumption is maintained under normal conditions, and adaptation

Atrial and ventricular fetal heart rate patterns in isolated congenital complete heart block detected by magnetocardiography

Autor: Chester B. Martin, Ronald T. Wakai, Arthur C. Leuthold

Publikováno v: American Journal of Obstetrics and Gynecology. 179:258-260

Atrial and ventricular fetal heart rate tracings from a patient with isolated congenital complete heart block treated with dexamethasone showed a remarkable degree of correlation and greater reactivity for the ventricular than the atrial fetal heart
