Abstract

Introduction: Most of women have described labor experience painful. Although there are many ways for reduction of labor pain, pharmacological ways are unsuitable because of their side effects on the respiratory system of newborns and mothers. Therefore, scientists have focused on non-pharmacological ways for reducing pain, nowadays. These methods are different and this verity shows a fact, that the perception of pain is not identical among people. Gate theory advocates this believe that there are many factors on pain perception such as age, sex, anxiety, and pain experience. Therefore, it is necessary that we know variety of pain-relief methods. This study was carried out based on Gate theory. Materials & Methods: This survey was a single-blind randomized clinical trial. Informed-consent forms were given to the mothers. Sampling Method was based on simple non-randomized and the number of sample was 146. They are divided into two equal groups, test and control. Data collection was carried out using questionnaire. Following determination of four injection site at the sacrum area, mothers in the test group were injected 0.1 ml of normal saline at these sites. While, mothers in the control group were received only blank injections. Then, the rate of pain was estimated in both groups using VAS at 10, 30, 45 and 90 minutes post-injection. Statistical analysis was performed by SPSS and Stata software using generalized estimation equation and Chi-square test. Results: No significant differences were observed in pain mean between test and control group at the above measured post-injection time points. Conclusion: The results showed that injection of normal saline has no influence on low back pain. Given these results, it is recommended that a single particular method has no impact on the reduction of pain, and therefore, a combination of alternative methods must be considered.
