Third stage of labor is one of the most important stages which can cause partum hemorrhage and maternal mortality

Background: Active management of labor in low risk women is controversial. The present research is a clinical trial study in which the researcher tries to determine the difference in the active and physiologic management of the third stage of labor. Materials and Method: The subject were divided into two group of 47.All subjects in active group received 10 unit syntocinone in 500 cc injection serum and cord immediate clamped and cut and placenta delivered by Brant-Andrews rnanover and the physiologic group received lee placebo in 500 cc serum,no clamping of the cord until pulsation had ceased and placenta delivered by minimal traction on the cord and maternal effort without Brandt-Androws rnanover after expulsive the placenta and membrane in view of completing were examined. Results: As a result, the case of post partum hemorrhage in physiologic group (14.587%) was higher than active group (10.64"%) but the statistical tests showed no significant difference between two groups (p=0.2945). The mean length of the third stage of labor in the physiologic group (I3minute) was higher than active group (t=2.379, df=92) but the statistical test showed no significant between the two groups. The statistical tests showed no significant difference between retained placenta and piece of the placenta and membrane (p=0.2428). The statistical tests showed no significant difference between duration and complication of the third stage in two groups. Conclusion: Therefore, the study showed that the physiologic management of third stage is a good choice for managing the low risk women.
