产程中运用膝胸卧位纠正枕后位的效果观察

Effect of using knee-chest position to correct occiput posterior position in the stages of labor

目的探讨在产程中运用开放式膝胸卧位矫正持续性枕后位的效果。方法 160例持续性枕后位产妇分为观察组和对照组,各80例。对照组采取传统常规方式待产,观察组采取开放式膝胸卧位来矫正胎位。比较2组产妇阴道分娩率,产程时间和新生儿窒息发生情况。结果观察组阴道分娩率92.5%(74/80)高于对照组81.5%(65/80),差异有统计学意义(P<0.05);第一产程及第二产程时间均短于对照组(P<0.01);新生儿轻度窒息率低于对照组(P<0.01)。结论开放式膝胸卧位对纠正持续性枕后位有效,可有效缩短产程,降低剖宫产率。

Objective To evaluate the application of knee-chest position to correct occiput posterior position in the stages of labor. Methods A total of 160 expectant women with persistent occiput posterior position were divided into the observation group and the control group,with80 cases in each group. The control group received conventional predelivery care,while the observation group adopted open knee-chest position to correct the position. The vaginal delivery rate,duration of labor and neonatal asphyxia were observed and compared between two groups.Results The vaginal delivery rate was 92. 5%( 74/80) in the observation group and was81. 5%( 65/80) in the control group,with a significant difference( P < 0. 05). The first stage and the second stage of labor were shorter in the observation group than those in the control group( P < 0. 01). There was 10 cases and 2 cases of mild neonatal asphyxia in the control group and observation group respectively,with a significant difference( P < 0. 01). Conclusion Application of chest-knee position is an effective method to correct persistent occiput posterior position. It can shorten the course of labor and reduce the rate of cesarean section.
