目的探讨骨盆摇摆配合气囊仿生助产对降低首次剖宫产率的效果。方法采取前瞻性研究方法,选择进入临产胎头未衔接的初产妇520例,观察组262例,在产程中应用骨盆摇摆配合气囊仿生助产技术分娩,对照组258例,在产程中应用常规舒适体位配合徒手旋转胎头分娩,对比两组分娩方式、剖宫产指征、阴道分娩产程时间及产后2 h平均出血量。结果 (1)观察组纠正胎方位成功率为90.84%、自然分娩率为91.98%,均明显高于对照组(P<0.01);观察组胎吸术率为1.15%、剖宫产率为6.20%,均低于对照组(P<0.01)。(2)观察组第一产程(8.93±2.15)h、第二产程(0.71±0.60)h、总产程(9.82±2.91)h,均短于对照组(P<0.01)。(3)观察组会阴侧切率17.21%、会阴Ⅱ度裂伤率6.56%,均低于对照组的42.02%、40.42%,差异有统计学意义(P<0.01)。(4)观察组产后2h内阴道出血量(155.708±42.68)ml,少于对照组的(248.57±81.68)ml,差异有统计学意义(P<0.01)。(5)观察组胎儿窘迫发生率为1.15%,明显低于对照组的9.30%(P<0.01);观察组未发生新生儿窒息率,对照组新生儿窒息率为3.10%。结论骨盆摇摆配合气囊仿生助产能有效降低首次剖宫产率,缩短第一、第二产程及总产程,减少母婴并发症的发生。 Objective To investigate the effect of pelvic swing combined with artificial delivery of balloon on decreasing cesarean section rate. Methods A prospective study was conducted to select 520 cases of unpaired primiparous women and 262 cases in the observation group. The pelvic swing and air bag biomimetic midwifery technique were used in the delivery process. The control group received 258 cases of conventional labor The position was matched with manual rotation of fetal head and childbirth. Contrasting the two modes of delivery, indication of cesarean section, duration of labor during vaginal delivery and average blood loss at 2 h postpartum. Results (1) The successful rate of fetal position correction in observation group was 90.84% ​​and spontaneous delivery rate was 91.98%, which were significantly higher than those in control group (P <0.01). The rate of fetus abortion in observation group was 1.15% and the rate of cesarean section was 6.20 %, All lower than the control group (P <0.01). (2) The length of the first stage of labor (8.93 ± 2.15) h, the second stage of labor (0.71 ± 0.60) h, and the total length of labor (9.82 ± 2.91) h in the observation group were shorter than those in the control group (P <0.01). (3) The rate of episiotomy in the observation group was 17.21%, the rate of laceration of the perineal second degree was 6.56%, which were all lower than those in the control group (42.02%, 40.42%). The difference was statistically significant (P <0.01). (4) The amount of vaginal bleeding within 2 hours after delivery in the observation group was (155.708 ± 42.68) ml less than that in the control group (248.57 ± 81.68) ml, the difference was statistically significant (P <0.01). (5) The incidence of fetal distress in the observation group was 1.15%, which was significantly lower than that in the control group (9.30%, P <0.01). The asphyxia rate in the observation group was 3.10%. Conclusions The pelvic swing combined with pneumatic assisted delivery can effectively reduce the first cesarean section rate, shorten the first and second stage of labor and the total process of delivery, reduce the incidence of maternal and infant complications.
