Introduction: Labor is a painful and prolonged process. Applying an uncomplicated method to reduce the length of delivery and severity of pain can increase maternal satisfaction and decrease the rate of cesarean section. Topical magnesium sulfate is empirically used to improve the effacement and dilatation of the cervix. The purpose of this study was to examine the effect of improving these variables on the intensity of labor pain.
Methods: This double blind clinical trial was conducted among 60 nulliparous women with full-term pregnancy. The participants were randomly divided into two groups of 30 individuals. The patients in the magnesium sulfate group received 10 cc of magnesium sulfate 50% and the control group were treated by 10 cc of distilled water poured on the cervix in the beginning of the active phase. Thereafter, the labor progress was studied in the groups. At the beginning of the active phase and two hours later, the severity of pain was measured using visual analog scale. Data analysis was performed using independent samples t-test, Mann-Whitney U test, Chi-squared test, and Fisher's exact test in SPSS software, version 17. P-value less than 0.05 was considered statistically significant.
Results: Prior to the intervention, the intensity of pain was not significantly different between the two groups. After 2 hours of intervention in the control group, the mean pain intensity significantly increased (P=0.04), while in the magnesium sulfate group, the pain intensity did not change significantly. Two hours after the intervention, the mean of effacement and dilatation in the magnesium sulfate group was higher (P˂0.001).
Conclusion: The application of topical magnesium sulfate reduced the duration of labor by improving the cervical condition. In addition, it reduces the intensity of labor pain. However, it did not have a negative effect on the severity of uterine contractions.
