The main purpose of this study is to explore the effect of unprotected perineal assisted delivery on the perineal lateral resection rate during delivery in primiparous women, with the aim of providing strong clinical evidence for optimizing delivery methods. The research method is as follows: from December 2023 to December 2024, 110 primiparous women who gave birth in the hospital were selected. The control group of mothers used traditional perineal protection assisted delivery method, while the experimental group used unprotected perineal assistance delivery method. A comprehensive evaluation was conducted on the effectiveness of two assisted delivery methods by observing and comparing the perineal lateral incision rate, degree of perineal laceration, duration of the second stage of labor, amount of bleeding within 2 hours postpartum, and Apgar score of newborns between two groups of parturients. The research results showed that the perineal lateral incision rate of the experimental group was 12.7%, significantly lower than the control group's 38.2% (P<0.05), indicating that unprotected perineal assisted delivery method has a significant effect on reducing perineal lateral incision rate; The incidence of grade I perineal lacerations in the experimental group was higher than that in the control group, but the incidence of grade II and above lacerations was lower than that in the control group (P<0.05), indicating that this method is equally effective in reducing severe perineal lacerations; In addition, the second stage of labor time in the experimental group was shorter than that in the control group (P<0.05), which may be related to differences in delivery assistance methods. However, there was no significant difference (P>0.05) in the amount of bleeding 2 hours postpartum and the Apgar score of newborns between the two groups, indicating that unprotected perineal assisted delivery does not increase the risk of postpartum bleeding or have adverse effects on the health of newborns. In summary, unprotected perineal assisted delivery can effectively reduce the rate of perineal episiotomy in primiparous women, reduce the occurrence of severe perineal lacerations, shorten the second stage of labor, and do not increase the risk of postpartum hemorrhage or affect the health status of newborns. Therefore, this method is worth promoting and applying in clinical practice.
