Objective  To explore the effects of utilization of new partogram on the progress of labor and intervention in the labor. Methods  We reviewed nulliparous women who had vaginal delivery at our hospital from January 1st, 2015 to December 31st, 2017. They were divided into control group (group A) (n=200; the old labor standard was used during this time) and observation group (the new labor standard was used at the same time). The observation group was sub-divided into group B (n=100, the duration of dilatation of cervix from 0 to 3 centimeters greater than or equal to 16 hours after parturition), group C1 [n=100; the second-stage duration (t) was greater than or equal to 2 hours, and less than 3 hours), and group C2 (n=100; t was greater than or equal to 3 hours). We compared the differences in intervention at the stages of labor such as using oxytocin to strengthen the contractions, artificial rupture of membranes, using phloroglucinol to soften the cervix, urinary catheterization, and manual rotation of fetal head among the groups. We also compared the differences in fetal presentation position, head tumor, fetal position, cephalopelvic disproportion and progress of the drop when the dilatation of cervix get to 10 centimeters among the groups. Results  In the comparison among group A, B, C1 and C2 in rates of using oxytocin to strengthen the contractions, using phloroglucinol to soften the cervix, urinary catheterization and manual rotation of fetal head, the differences were statistically significant between group C2 and the other groups (P<0.008 5). The differences among group C1, C2 and A were statistically significant in duration of the first stage of labor (P<0.05). The same result was found between group B and A in duration of the second stage of labor (P<0.05). In the comparison of the different ratios of fetal presentation position between group A and C1, and group A and C2, when the dilatation of cervix get to 10 centimeters, the differences were significant (P<0.017), except at +1 position. The differences in whether the fetal presentation was producing head tumor and occipital anterior position among group A, C1, and C2 were statistically significant (P<0.017), but there was no difference between group A and C1 (P>0.017) in occipital anterior position. In the comparison of the different progress of the drop when the dilatation of cervix had got to 10 centimeters, 0–1 hours: the differences were statistically significant among group A, C1, and C2 (P<0.05) ; 1–2 hours: the difference was statistically significant between groups C1 and C2 (P<0.05). In group C1, there was a statistically significant difference between 0–1 hour and 1–2 hours (P<0.05). In group C2, there was no statistically significant difference among 0–1 hour, 1–2 hours and 2–3 hours (P>0.05). Conclusions  According to the new labor standard, the rates of intervention in the labor would not increase, but when the second-stage duration is greater than or equal to 3 hours, the frequency would increase. We should deal with the abnormal factors affecting labor in time, and try to control the duration in 3 hours.
