Abstract Objective: To study the value of perineal unprotected delivery technique in normal delivery of low risk pregnant women. Methods: 104 low risk pregnant women were selected and were divided into two groups according to the random number method from March 2017 to October 2018. The women in the observation group were given unprotected perineal delivery, while women in the control group were given traditional perineal delivery. The rates of perineal incision and perineal integrity, the perineal fissure injury degree, the pain degree, the second labor time, the bleeding amount, and the adverse pregnancy outcomes of women in the two groups were observed and evaluated. Results: The perineal integrity rate of women in the observational group was 44.2%, which was significant higher than that (17.5%) of women in the control group (P<0.05). The rate of perineal incision and the proportion of Ⅰ and Ⅱ degree of perineal laceration of women in the observational group were 19.2% and 17.3%, which were significant lower than those (48.1% and 66.7%) of women in the control group (P<0.05). There was no any women with Ⅲ degree perineal laceration in both groups. The the proportion of the pain degree Ⅱ and Ⅲ, the time of the second stage of labor, the bleeding amount during labor or postpartum bleeding amount, and the incidences f postpartum hemorrhage and neonatal asphyxia of women in the observational group were significant less than those of women in the control group (P<0.05). Conclusion: The perineal unprotected delivery technique used for low risk pregnant women during delivery has high clinical value, which is beneficial to reduce the risk of perineal laceration and perineal incision, so it is worth application and promotion.
