摘要:目的 比較手-膝式俯臥位分娩與傳統平臥位分娩在改善分娩結局的臨床分析。方法 將121例分娩孕婦隨機分為對照組60例(應用平臥位分娩)、觀察組61例(在第二產程應用手-膝俯臥位分娩),觀察兩組第二產程進展、產后出血量、胎兒窘迫、肩難產發生情況。結果 觀察組產婦出血量未增加,胎兒宮內窘迫發生率觀察組低于對照組,肩難產的發生觀察組低于對照組,第二產程時間觀察組少于對照組。結論 采取手-膝式俯臥位分娩方式對提高順產分娩質量,促進分娩順利進行具有積極意義。

Abstract:Objective Compare hand-knee type prone position with the traditional hypothesis childbirth labor in improving the labor outcomes of clinical analysis.Methods 121 pregnant women were randomly divided into control group of 60 patients (using the hypothesis of delivery), the observation group, 61 cases of prone position (in the second hand labor application - knee childbirth), observe two groups of the second progress in labor, postpartum blood loss, fetal distress, shoulder dystocia is happening.Results Observation group the bleeding is not increased maternal and fetal intrauterine distress group is lower than the control group,the incidence of shoulder dystocia in observation group is lower than the control group,the second labor time observation group is less than the control group.Conclusion Hand - knee type prone position delivery ways to improve the quality of natural childbirth, promote positive significance for the smooth delivery.

現在國內外許多產科都提倡自然分娩已經不限制分娩體位,讓產婦自主選擇舒適的體位分娩,一些新的產婦分娩體位可以有多種,比如坐位、蹲位、站位、跪位、俯位、側位、半臥位及臥位等。原始古代產婦多采用快速、簡便、舒適的豎式體位分娩,如站、蹲、坐、跪等。
手-膝式俯臥位分娩的優勢:因為體位的改變,手-膝式俯臥位解除了平臥位時的腹主動脈受壓,使子宮供血更充分,從而胎兒可以從母體得到更多的血液,大大降低胎兒因塌陷子宮使腹主動脈受壓而可能發生的胎兒窘迫,而且根據MR掃描手-膝俯臥位時女性骨盆出口徑線和坐骨棘徑線要長于平臥位,骨盆的坐骨結節徑線長于其它體位。手-膝俯臥位時產道更寬敞,胎兒更易于通過,肩難產發生率減少,對產婦的損傷減小[1]。對產婦和新生兒均有利。手-膝式俯臥位分娩還可減輕腰背的疼痛。……
