对９０例足月妊娠、无头盆不称的初产妇进行研究观察，随机分为两组，各４５例．行气囊助产的４５例为观察组，另外４５例阴道分娩者为对照组，分别计算其产程、产时出血量、新生儿Ａｐｇａｒ评分的平均值并进行观察比较．结果（１）观察组平均产程是５２６ｈ，较对照组平均产程１０６２ｈ明显缩短（Ｐ＜００１），两组比较，有高度显著性差异．（２）宫颈Ｂｉｓｈｏｐ评分≥７分的产妇效果较好，宫颈Ｂｉｓｈｏｐ评分４～６分者，效果较差．（３）观察组及对照组产妇产时出血量及新生儿产后Ａｐｇａｒ评分均无明显差异（Ｐ＞００５）．结果表明：气囊助产是一种在阴道分娩中安全、有效、能缩短产程的方法，并能有效地实施计划分娩，提高分娩质量． 90 cases of full-term pregnancy, no head basin primiparous were observed, were randomly divided into two groups, each 45 cases. Forty-five patients undergoing balloon midwifery were selected as the observation group, and 45 other vaginal delivery women as the control group. The average duration of labor, the amount of bleeding during labor and the Apgar score of neonates were calculated and compared. Results (1) The average length of labor in observation group was 526h, which was significantly shorter than that in control group (P <001). There was a significant difference between the two groups. (2) Cervical Bishop score≥7 points of the maternal better, cervical Bishop score of 4 to 6 points, the effect is poor. (3) There was no significant difference between the observation group and the control group in the amount of maternal bleeding and neonatal Apgar score (P> 005). The results showed that airbag midwifery was a safe and effective method to shorten labor during vaginal delivery and could effectively plan delivery and improve delivery quality.
