临产后胎头下降程度两点法测定与分娩关系的探讨

An Approach to the Relation between Two-point Determin-ation of Decending Degree of Fetal Head and Delivery

对分娩进入活跃早期的初产妇随机抽样测定胎头下降程度８２例，分成四组进行对比分析。其中，头高阴道分娩组（Ａ组）４０例，头低阴道分娩组（Ｂ组）２２例，头高剖宫产组（Ｃ＿１组）１１例，头低剖宫产组（Ｃ＿２组）９例。结果表明，Ａ、Ｂ组间活跃期（Ｐ＜０．０１），第二产程（Ｐ＜０．０５），Ａ、Ｃ＿１组间胎儿体重（（Ｐ＜０．０１），Ｂ，Ｃ＿２组间胎儿体重（Ｐ＜０．０５）等，均存在统计学上的明显差异。作者认为应根据抬头下降的程度观察产程，并根据不同的临床特点进行转化治疗。

The degree of descendence of fetal head in early active stage of labor in 82 primiparaechosen at random was examined in our hospital from August 1994 to May 1995, The exami-nees were divided into 4 groups:Group A,high head(frontal part of fetal head≥6cm fromostium vaginae)vaginal delivery,40 cases;Group B,low head(frontal part of fetal head≤6cm from ostium vaginae,about S-1 vaginal delivery,22 cases;Group C1,High head ce-sarean section,11 cases and Group C2,low head cesarean section, 9 cases. The resultsshowed significant differences existed in active stage(P<0.01)and second stage of labor(P<0.05)between Group A and B,in fetal weight between Group A and C1,(P<0.01)andbetween Group B and C2(P<0.05);It is suggested that transformation of treatment shouldbe carried out according to the degree of descendence of fetal head and clinical manifesta-tlons.
