The aim of this thesis is to examine the effect of the placenta delivery method on women's postpartum pain, bleeding and comfort. It is a randomized controlled experimental study. The research will be conducted at Mersin Tarsus state hospital between March 2024 and August 2024. The study will be conducted with 140 primiparous women, 70 primiparous pregnant women in the experimental group and 70 primiparous pregnant women in the control group, who meet the research criteria and apply to the delivery room of Tarsus State Hospital between these dates. The research will be carried out with a control group (those receiving routine hospital protocol/where the placenta is delivered with controlled cord traction) and an experimental group (physiological separation of the placenta with a mixed method). Interventions applied to research groups vary depending on the characteristics of the group. In both groups, interventions in the delivery room will be performed by the researcher midwife. If any complications develop during the research, independent of the interventions, if the woman undergoes a cesarean section, or if situations that meet the exclusion criteria occur, that woman will be excluded from the sample. The researcher will apply a routine hospital birth management protocol to both groups during the first three stages of labor. However, the way the placenta is delivered in the third stage (physiological with mixed management or controlled cord traction with active management) will differ. The researcher will apply the Visual Analogue Scale (VAS) twice, at the beginning and at the end of the third phase of labor, apply the Postpartum Comfort Scale at the 4th postpartum hour, and record hemoglobin and hematocrit values at admission to the hospital, which is the hospital's routine protocol, and in the hemogram test at the 6th hour postpartum. HB and HCT values will be used to interpret the amount of postpartum bleeding. The hypotheses of the research are as follows; H1: In the active management of the 3rd stage of labor, delivery of the placenta with controlled cord traction affects the woman's perception of postpartum pain.

H2: In the active management of the 3rd stage of labor, delivering the placenta with controlled cord traction affects the woman's amount of postpartum bleeding.

H3: In the active management of the 3rd stage of labor, delivering the placenta with controlled cord traction affects the woman's postpartum comfort level.

H4: In the mixed management of the 3rd stage of labor, physiological delivery of the placenta affects the woman's perception of postpartum pain.

H5: In the mixed management of the 3rd stage of labor, physiological delivery of the placenta affects the amount of postpartum bleeding of the woman.

H6: In the mixed management of the 3rd stage of labor, physiological delivery of the placenta affects the woman's postpartum comfort level.
