[Progression trend comparison of labor in women of our day with the freidman curve]

ABSTRACT

Rapid development of science in determination of labor trend shows embossed differences in labor curve of these days and Friedman curve. These developments include lack of deceleration phase and quick progression in active phase due to the differences in age, race and increase of midwifery interventions during the delivery. This study was performed to compare modern labor curve with Friedman curve. The present descriptive study was performed on 665 parturient women who referred to Fasa Shariati hospital during one year. Inclusion and exclusion samples had not taken any sedation or induction for labor. Data were collected by educated midwives. There was a significant difference between the two groups regarding the mean of dilatation velocity [p<0.05] and stage of labor [p<0.05]. However, a significant difference was not observed between the active phase and third stage of labor. Also the mean of active phase and second stage of labor in both nulli and multipara women of today showed a significant difference with the women in the Friedman study [p<0.05]. This study shows that the labor curve of these days is different with Freidman labor curve and the maximum of dilatation velocity happens in over 5 cm. Therefore, it is suggested to avoid any early midwifery and surgery intervention before 5 cm dilatation
