Objective : To determine the effect of an active management of a labor program on the rate of cesarean section
and labor outcomes in low-risk nulliparous pregnancies in a setting with limited resources.
Materials and Methods : Nine hundred and seventy-five low risk nulliparous pregnant women were randomized to
receive either active management of a labor program (n = 325) or conventional management (n = 650). The rate
of cesarean section and labor outcomes were compared between the two groups using Chi-square and t-tests.
Results : The subjects in the active management program had significantly shortened first stage of labor and
total duration of labor compared with the conventional group (538.0 + 242.9 min vs 589.4 + 263.8 min, p <
0.05, 539.3 + 261.4 min vs 610.3 + 264.4 min, p < 0.001, respectively). There was no statistical difference
found in the rate of cesarean section and other labor outcomes.
Conclusion : The active management program shortened the first stage and duration of labor in low-risk
nulliparous pregnant women.
Keywords : Active management of labor, Cesarean section, Randomized controlled trial
