Determining the Time of Spontaneous Separation of Placenta and the Factors Affecting This Time After Vaginal Delivery

INTRODUCTION: The purpose of this study is to determine the timing of spontaneous separation of placenta after vaginal delivery and the factors affecting this time.
METHODS: Between 01.03.2016-01.01.2017 in the department of Obstetrics and Gynecology in İstanbul Dr. Lütfi Kırdar Kartal Education and Research Hospital.198 patients referred for vaginal delivery were included in our study. Following vaginal delivery, the placenta was expected to be spontaneously separated and checked at intervals of 5 minutes.
RESULTS: The separation time of the placenta was determined to be 11,69±6,09 minutes. It has been observed that the time for placental separation in induction-receiving and previously delivered patients is shortened. The placenta of 96% of the patients left within the first 20 minutes. In 5 of 198 patients the placenta did not spontaneously separate within 30 minutes and was taken by hand.
DISCUSSION AND CONCLUSION: In this study, the spontaneous separation time of the placenta was observed at intervals of 10-15 minutes. It was thought that 20 minutes should be determined as the threshold value for the spontaneous separation of the placenta. Taking induction and previously giving birth has been identified as a shortening factor.
