The prediction of the progress of labor using the Friedman Curve in Primiparous Thai women

Abstract

At present most of studies showed that the duration of labor of women is longer than in the past making it necessary to conduct the study to confi rm the sensitivity of the Friedman Curve in the prediction of labor progress in the fi rst stage of labor. This study used convenient sampling to recruit primiparous women in a labor room at a central hospital in southern Thailand among which 350 women were used in the analysis for the sensitivity prediction of the Friedman Curve. The results showed that the Friedman Curve has moderate sensitivity in predicting the progress of labor throughout the fi rst stage of labor: latent, acceleration, and maximum slope phases (correction of prediction 72%, 79%, 78%, respectively) but the deceleration phase showed a high sensitivity (85%). Thus, using the Friedman Curve to monitor the progress of labor is still reliable in Thai women.
