Last week’s webinar, covering research on a new method to assess labor progress, continues to stimulate comment and debate. The session described a whole new labor curve concept, one that adapts to the multiple factors affect dilation directly and change as labor advances. Recent peer reviewed publications report a five-fold improvement in the rate of identification of first time mothers who actually underwent a cesarean for slow labor using the PeriCALM Curve compared to the rate using the current fixed labor curves that are based on time only (70% vs 12%).
The research, outlined in two articles recently published in the American Journal of Obstetrics & Gynecology, was reviewed by Dr. Emily Hamilton during a lunchtime session offered by PeriGen. The session, titled “Rethinking the Labor Curve,” was recorded and can be viewed here.
Dr. Hamilton led the research team that applied a modern, mathematical approach to the assessment of labor. The team found that the utility of contemporary labor curves was limited because of, among other things, a wide degree of variation in the early stages of labor. In fact, it is not until late labor when dilation reaches six centimeters that this variation enters useful limits and the contemporary curves can be used. The new approach can be applied earlier to assess two essential processes for vaginal birth (dilatation and descent). Results are expressed with percentiles and graphs.
We look forward to hearing your thoughts and questions too.
