第二产程

第二产程：R组（85.7士39.3）min；

The difference was statistically significant . The second stage of labor : Group R ( 85.7 + 39.3 ) min ;

第二产程胎先露下降至棘下3cm时前壁和宫底部肌层较活跃期明显增厚（P<0.01）。

There was significant thickening of the anterior and fundal myometrium during the second stage of labor after the fetal head descended to + 3 station by digital examination ( P < 0.01 ) .

研究组800例，在第二产程胎头娩出后即口服米索前列醇600μg；

For the study group , 600 μ g of misoprostol was given orally after delivery of fetal head at the end of the second stage .

方法随机选取93例第二产程急诊剖宫产，采用子宫下段“U”形切口的娩头入路。

Methods " U " incision was adopted in93 cases chosen randomly during emergency cesarean section in the second stage of labour .

RⅡ，B组的第二产程延长161%，183%，RⅠ组无产程延长。

The second birth process of the R ⅱ and B groups was prolonged by 16.1 % and 18.3 % , while that of R ⅰ group was not prolonged .

结论第二产程急诊剖宫产子宫下段U形切口采用屈肘上托力娩头为最佳娩头方法。

Conclusions The method of fetal head delivery with uterus " U " incision using bending elbow upward during emergency cesarean section in the second stage of labour was the best .

滞产、第二产程延长者新生儿窒息率经统计学处理明显高于正常产程与第二产程正常的新生儿窒息率（P0.01）。

And compared with natural process of labor , in presence of prolonged labor and prolonged second stage of labor , the incidence rate of neonatal asphyxia rate increased significantly ( P0.01 ) .

在分娩活跃期和第二产程，Ⅰ、Ⅱ组VAS明显低于Ⅲ组（P<0.05）。

In the active and expulsive stage , the VAS sores of group ⅰ and ⅱ were lower than those of group ⅲ( P < 0.05 ) .

B组运动阻滞程度明显高于其它两组P<0.01，第一产程和第二产程虽延长，但均未超过常规时间。

The degree of motor block in the group R was less than that in the group B ( P < 0.01 ) . The first and the second duration of labour in the group R and B were prolonged , but it did not exceed the routine time .

分A组：第二产程少于或等于120min，有3436例。

Group A consisted of 3436 patients with a second stage of 120 minutes or less ;

结果表明：第二产程时两组血清PRL值无显著差异。而产后半小时早吸吮的母亲体内血清中PRL水平明显高于未吸吮的血清PRL值。

Results : There was no significant difference of serum PRL between the two groups , while the serum PRL level of early suck group after delivery was obviously higher than that of no suck group .

水针组和对照组第二产程时间及催产素使用情况与PCEA组比较有显著性差异（P<0.05）。

There were aloes a statistically significant difference between the aqua acupuncture group , the control and the PCEA group in the second labor process , the use of oxytocin ( P < 0.05 ) .

结论：第二产程出现异常CTG图形对胎儿酸血症有预测价值，混合性酸血症及代谢性酸血症对新生儿结局影响较大。

Conclusion : The pathological FHR patterns during the second stage of labor have predictive value for fetal academia and the mixed and metabolic academia have more greatly effect on neonatal outcome than the respiratory one .
