Abstract:OBJECTIVE To investigate the effects of unprotected perineal delivery technology on maternal and child complications, perineal protection and postpartum pain in primipara. METHODS 50 primipara patients were selected as study subjects from June 2018 to December 2018 and divided into two groups according to random sampling method. The control group was given traditional vaginal delivery method. The observation group was given unprotected perineal delivery. The technique was performed in 25 cases, and the degree of perineal laceration, the degree of perineal pain, the amount of postpartum hemorrhage, the time of second labor, the length of hospital stay, and the incidence of maternal and child complications were observed and evaluated. RESULTS The proportion of perineal integrity in the observation group was higher than the control group, while the proportion of perineal I degree and II degree laceration and the proportion of perineal edema were lower than the control group, P﹤0.05. The proportion of perineal pain in grade 0 and grade I of the observation group was higher than that of the control group, while the proportion of perineal pain in grade II and III was lower than the control group, P﹤0.05. There was no significant difference between the observation group and the control group in the amount of postpartum hemorrhage and the second stage of labor (P﹥0.05). The hospitalization time of the observation group was lower than the control group, P﹤0.05. The incidence of maternal and child complications in the observation group was lower than the control group, P﹤0.05. CONCLUSION Unprotected perineal delivery technology had high clinical value in primipara, which was beneficial to reduce the incidence of maternal and child complications and protect the perineum. It was worthy of application and promotion.
