investigation Effect of Softening and Improvement Cervical Effacement and Dilatation on Pain Relief

Backgrounds: Childbirth is a painful process. One of the mechanisms of this pain is cervical elongation, followed by compression of nerve ganglion. It is possible that with cervical softness, the pain and discomfort caused by it's stretching will be reduced. Magnesium sulfate is a medicine that is used empirically in some hospitals in the country to improve the effacement and dilatation of the cervix. The aim of this study was to evaluate the effect of softening and improvement of cervical effacement and dilation after local administration of magnesium sulfate on the severity of labor pain.Material and Method: 70 primiparous women with term pregnancy were studied in this study. The participants were divided in 2 group of 35 people .In the magnesium sulfate group, when cervical dilation was 3-4 cm, 5 g of magnesium sulfate (50%) was and in the placebo group distilled water was poured on the cervix, then labor proses was examined in two groups. Before the intervention, two hours later, pain intensity was measured using visual analog scale (VAS). Data were analyzed using SPSS software.Result: After two hours of intervention, effacement and dilatation in magnesium sulfate group was higher (P = 0.001). After two hours in the control group,0/71 increased in the mean of pain severity, which was significant (P = 0.04), whereas in the magnesium sulfate group, the pain severity did not change significantly.Conclusion: It may be possible to reduce the severity of the pain caused by the stretch of the cervix by improving the effacement, dilatation and softening of the cervix during the labor process, but this effect does not seem so important that it can be used as a method solely to reduce labor pain.
