摘要:

[目的]研究针刺分娩镇痛的作用机制。[方法]以Keele标尺图评级法及视觉模拟评分法(VRS)疼痛分级法作为针刺分娩镇痛效果评定方法,并通过记录产妇产程等来观察针刺对母婴的影响,通过观察针刺前后及相应时间产妇外周血中β-内啡肽(β-EP)及5-羟色胺(5-HT)浓度变化,探讨该方法的镇痛机制。[结果]针刺能有效减轻第一产程分娩疼痛,与自然分娩对照组相比有显著性差异(P<0.05),对母婴无不良影响且能缩短产程。该方法能明显提高产妇外周血中β-EP及5-HT浓度。[结论]以针刺作为分娩镇痛手段,具有操作方便、安全,镇痛效果可靠,无副作用等优点,其镇痛效果可能是通过中枢镇痛系统与对子宫的直接作用共同实现的。

Abstract:

[Objective] To research the mechanism of acupuncture for relifing labour pain. [Methods] To evaluate the effect for relifing labour pain, we used Keele staff diagram grade-evaluating method and VRS pain-classifying method as the observation. To observe the effect of acupuncture on mother and infant, such as the stages of labor of the parturient were recorded. To research the mechanism of relifing labour pain,we observed the concentration changes of β-EP and 5-HT in the blood of parturient before and after acupunctured. [Result] The acupuncture can effectively relieve labour pain in the first stage of labor. And compared with the comparing group, it differed significantly (P<0.05) and had no harmful effects on the mother and infant. This method can obviously improve the concentration of β-EP and 5-HT in the blood of parturient. [Conclusion] Taking the acupuncture as the means of relifing labour pain has the merits of convenient manipulation, safety, reliable effect on analgesia and without side effect and so on. The effect of acupuncture for relifing lohour pain may be produced by the joint-work of CNS and directly effect on the uteri.
