Abstract：
OBJECTIVE: This research was done to compare obstetric pain, anxiety and cervical dilatation between an epidural analgesia group and a control group.
METHODS: Participants were assigned to the experimental or control group depending on their decisions for pain relief. Subjective / objective obstetric pain, anxiety level and cervical dilatation were measured and ANOVA was used for comparison of groups and paired t-test to make pre-post comparisons.
RESULTS: Homogeneity of pain, anxiety and cervical dilatation were assessed at the latent phase. Cervical dilatation was larger in the control group than the experimental group, at both the active and the transitional phase (F=22.9, p<.001; F=39.9, p<.001 respectively). The degree of pain and anxiety were not significantly different between the groups. Within the experimental group, subjective / objective pain and anxiety level were significantly lower postanalgesia compared to pre-analgesia in the active phase. All variables, except for sweating in the objective pain measurement, changed significantly at the transient phase.
CONCLUSIONS: The results of this evidence-based research indicate that epidural analgesia while effective in relieving pain and anxiety may have an adverse effect on the cervix during labor stage I. Epidural analgesia should be used carefully during cervical dilatation in labor stage I.

摘要：
目的：这项研究是为了比较产科疼痛，硬膜外镇痛组与对照组之间的焦虑和宫颈扩张。
方法：根据患者疼痛缓解的决定，将参与者分为实验组或对照组。主观/客观产科疼痛，测量焦虑水平和宫颈扩张,采用方差分析进行组间比较,采用配对t检验进行前后比较.
结果：疼痛的同质性，在潜伏期评估焦虑和宫颈扩张。对照组宫颈扩张明显大于实验组,在活动和过渡阶段（分别为F=22.9，p<.001；F=39.9，p<.001）。两组之间的疼痛和焦虑程度没有显着差异。在实验组中，与活动期的镇痛前相比,主观/客观疼痛和焦虑水平显著降低了镇痛后.所有变量,除了在客观疼痛测量中出汗，在瞬态阶段发生了显著变化。
结论：这项循证研究的结果表明，硬膜外镇痛在有效缓解疼痛和焦虑的同时，可能会对产程I期宫颈扩张产生不良影响。
