Effect of Perineum Block Anesthesia Combined with Unprotected Perineal Delivery on the Perineal Integrity Rate and Maternal-Infant Outcomes in Primiparas Taking Health Products Containing Traditional Chinese Medicine

Abstract

Objective. The purpose of the study was to investigate the effect of perineum block anaesthesia combined with unprotected perineal delivery on the perineal integrity rate and maternal-infant outcomes in primiparas taking health products containing traditional Chinese medicine (TCM). Methods. A total of 120 puerperae admitted to our hospital from July 2019 to July 2020 were selected as study subjects and divided into group A (n = 60) and group B (n = 60), according to the number table method. Both groups took health products containing TCM, and the puerperae in group A received perineum block anaesthesia combined with unprotected perineal delivery, while those in group B were treated with routine delivery combined with routine protected perineal delivery. After that, the effect of different delivery modes on the perineal integrity rate and maternal-infant outcomes in puerperae was analyzed by the comparison of delivery condition, perineal condition, and postpartum quality of life between the two groups. Results. There were no significant differences in average age and other general data between the two groups ( $P>0.05$ ); the duration in first, second, and third stages of labor in group A was significantly lower than that in group B ( $P<0.001$ ); the Apgar score in group A was significantly higher than that in group B ( $P<0.001$ ); the number of puerperae with integrated perineum in group A was significantly higher than that in group B ( $P<0.05$ ), while the number of puerperae receiving episiotomy in group A was significantly lower than that in group B ( $P<0.05$ ); the quality of life score in group A was significantly higher than that in group B ( $P<0.001$ ); the incidence of maternal postpartum complications in group A was significantly lower than that in group B ( $P<0.05$ ). Conclusion. Perineum block anaesthesia combined with unprotected perineal delivery can effectively shorten maternal labor duration, improve perineal integrity rate, and reduce laceration of perineum, with a significant therapeutic effect, which is worthy of application and promotion.
