对６０例单胎、头先露、正式临产需手术助产分娩的初产妇（研究组）及６０例单胎、头先露、正式临产经阴道自然分娩的初产妇（对照组）的宫缩图进行分析。结果表明：研究组宫缩图的类型平行型及多交叉型显著多于对照组（Ｐ＜０．０５）；对照组宫缩图的类型单交叉型显著多于研究组（Ｐ＜０．０５）；研究组宫缩图第一交叉出现至胎儿娩出时间及至产程图交叉的时间均明显长于对照组（Ｐ＜０．０５）；研究组第一交叉出现时宫颈口扩张明显小于对照组（Ｐ＜０．０５）；研究组第一交叉出现时先露部明显高于对照组（Ｐ＜０．０５）。提示：分娩时以图表形式客观反映子宫收缩情况，能及时识别头位难产，指导产程处理，有非常重要的意义，值得推广应用
Sixty primiparous women (study group) with 60 singletons, first-born, formal abortion with operative midwifery, and 60 first-born women Figure for analysis. The results showed that the types of uterine contractions in the study group were significantly more than those in the control group (P <0.05), while those in the control group were significantly more than those in the study group (P <0.05) ). The time from the first cross of the uterine contraction to the time of fetal delivery and the crossing of labor to birth was significantly longer in the study group than in the control group (P <0.05). In the study group, the cervical intervertebral dilatation at the first cross was significantly smaller than that in the control group <0.05). In the first crossover study group, the exposed area was significantly higher than that in the control group (P <0.05). Tip: childbirth objectively reflect the form of a contraction of the uterus in the form of a chart, can identify head dystocia in a timely manner, guiding the production process, has a very important meaning, it is worth promoting application
