Objective: In this study, it was aimed to determine the effect of late cord clamping with skin-to-skin contact immediately after delivery on placental abruption time, type of separation, amount of postpartum hemorrhage and postpartum comfort in primiparous pregnant women who gave vaginal delivery. Design: The research is an experimental-type randomized controlled trial. Population: The study was completed with 126 primiparous pregnant women, 63 control and 63 experiments, who were randomized in the clinic. Methods: Placental abruption time, type of abruption, participant’s entry and postpartum 6th hour hemoglobin and hemotocrit levels were recorded by the researcher via Personal Information Form. Main Outcome Measures: Skin-to-skin contact and late cord clamping shorten the placental abruption time, reduce the amount of postpartum hemorrhage, increase the level of postpartum comfort and have no effect on the type of placental abruption. Results: When the placental abruption types were compared in the experimental and control groups, 47.6% of the experimental group had Duncan type, 52.4% had Schultz type, 36.5% of the control group had Duncan type and 63.5% had Schultz type, and no statistically significant difference was found. Skin-to-skin contact was reduce the amount of postpartum hemorrhage and the postpartum comfort levels of the experimental group were found to be higher than the control group. Conclusions: Skin-to-skin contact and late cord clamping reduce placental abruption time, reduce the amount of postpartum hemorrhage, and increase postpartum comfort of the mother. It has no effect on the way the placenta detaches. Link to the trial registry: [www.clinicaltrials.gov](http://www.clinicaltrials.gov) Clinical trial number is NCT06011096.
