Methods : It is a clinical trial study to compare the effect of injection of oxytocin to mothers intramuscularly , nipple stimulation and physiologic manangment of third stage of delivery on length and bleeding range of this stage on 150 pregnant women from first to fourth pregnancy , referring to labor room of taleghaani hospital . The purpose of present study is research which were placed accidentally into three groups . in the first group immediately after delivery and cutting the umbilical cord , 10 units of oxytocin was injected into the mothers muscle , in the second group , right after delivery and cutting umbilical cord and take the baby in mother breast and the last group manage physiologically and did not receive any medicines . Then length and range of bleeding of the third stage of delivery in each group was studied and analyzed statistically .. results : Findings indicated that the average age of pregnant woman who were participated in this study was about (0/406)+26/39 years and according to Chi-square test it was determined that age attribution , delivery numbers , educational level , pregnancy age , abortion numbers and pregnant mothers jobs in three groups are nearly similar to each other . The results showed that the min amount of bleeding of third stage of delivery from low to high was (167/147)±306/7) in the physiologically managed group , (220/21)±321/20 in oxytocin ejection group and (219/71)±329/2 and the min of the length of third stage of delivery from low to high was (4/91)±8/83 in the nipple stimulation group , (5/54)±10/42 in oxytocin ejection group and 2(8/07)±11/20 in physiologically managed group . And these differences was not statistically significant (p=0/821 وp=0/162) . conclusion : As there was not any impressive and meaningful difference in distinction of average bleeding of third stage of delivery and the length of period in these groups ,it seems that using oxytocin injection ,does not have any positives effect on the amount of bleeding of the third stage of delivery.
