Abstract:Objective To explore the application effect of novel pulse perineal protective delivery technique in primipara undergoing vaginal delivery. Methods A total of 229 primipara who met the indications for vaginal trial delivery and planned vaginal delivery in the obstetrics department of Nanjing Drum Tower Hospital from March to December 2021 were selected and randomly divided into observation group ( 113 cases) and control group (116 cases) using a random number table method. The control group received the delivery with traditional perineal protection, and the observation group received the delivery with the novel pulse perineal protection of our hospital (which has been authorized to be protected by the written works of the national copyright administration, registration number: 2020-A-00981283). The delivery outcome, postpartum perineal pain, breastfeeding and satisfaction of the two groups were observed. Results The time of the second stage of labor, the amount of postpartum hemorrhage, perineal laceration with degree Ⅱ and above, catheterization rate and hospital stay in the observation group were significantly lower than those in the control group (P＜0.05). The number of early relief of bedrest and the rate of postpartum exclusive breastfeeding were significantly higher than those in the control group (P＜0.05). There was no significant difference in neonatal Apgar score, umbilical artery pH, and umbilical artery base excess (BE) between the two groups (P＞0.05). Conclusion The novel pulse perineal protection technique can speed up the progress of the second stage of labor, reduce perineal injury and postpartum hemorrhage, and improve pure breastfeeding.
