Journal of Maternal-Fetal and Neonatal Medicine Publishes PeriGen Research on Uterine Tachysystole

PRINCETON, N.J., Aug. 15, 2012 /PRNewswire/ -- PeriGen, Inc., an innovative, national provider of fetal surveillance systems, today announced the publication of research on uterine tachysystole in the June issue of the Journal of Maternal-Fetal and Neonatal Medicine, which showed that high contraction rates were common in deliveries with normal blood gases at birth. The study revealed that fetal heart rate decelerations, in response to any level of contractions, and especially during the last two hours of labor, were more closely associated with metabolic acidosis than high contraction rates alone. Many babies were able to tolerate high contractions without consequence. More than 10% of the 3,636 patients in this study experienced contractions occurring more frequently than 5 in 10 minutes in times near delivery.

"This is the first large-scale study to measure how contraction rates evolve during labor, and the results of this study help to clarify the clinical significance of high contraction rates," said Emily Hamilton, MD, PeriGen's SVP of Clinical Research, and one of the authors of the study.

In addition to Dr. Hamilton, the authors of this study include Daniel O'Keeffe, MD, Executive Vice President of the Society for Maternal-Fetal Medicine, Thomas J. Garite, MD, Professor Emeritus at the University of California at Irvine School of Medicine, G. Eric Knox, MD, founding member of the National Patient Safety Foundation, and Philip Warrick, PhD, Senior Biomedical Research Engineer at PeriGen.

"Without PeriCALM Patterns, it would have been impossible to analyze the 13.7 miles of fetal heart rate tracings in this study," added Dr. Hamilton.

PeriCALM® Patterns™ is patented, electronic fetal monitoring pattern recognition software that identifies and measures baseline, baseline variability, fetal heart rate decelerations and uterine contractions during labor. The PeriCALM Patterns tool used to conduct this research is embedded in all of PeriGen's fetal monitoring and perinatal systems.
