Objective To explore the effect of moderate perineal protection technique with two fingers protection points on delivery outcomes of primipara. Methods A total of 329 cases of vaginal delivery were randomized into 165 cases in an experimental group and 164 cases in a control group. In the experimental group, the highest point of the frontal bone of the fetus and the intersection of the perineal central tendon was used as the point of focus for moderate perineal protection, while in the control group, the point of focus was 2 cm away from the posterior perineal coalition for moderate perineal protection. The duration of the second stage of labour, degree of perineal laceration, wound suture time, haemorrhage at 2 hours postpartum, oedema at 24 h postpartum, wound pain at 48 hours postpartum and the Apgar score of newborns 1 min were compared between the two groups. Results In the experimental group, the degree of perineal laceration, the time of wound suture, the amount of bleeding 2 hours after delivery, and the degree of perineal pain 48 hours after delivery were significantly lower than those in the control group (all P<0.05). There were no significant differences in the second stage of labor, the degree of perineal edema 24 h after delivery, and the Apgar score of newborns 1 min between the two groups (all P>0.05). Conclusion The moderate perineal protection technique using the intersection of the highest point of the fetal frontal bone and the perineal central tendon as the focus point can effectively reduce perineal injuries and increase the comfort of primipara in the postpartum period.
