BACKGROUND AND OBJECTIVE: Nowadays, for pain relief in labor, there are pharmacological and nonpharmacological methods which are used in obstetric field. One of these methods is irritation of painful area by painful stimulus which is seemed that release local endorphin and act base on gate theory. So, this study was carried out to evaluate the effect of normal saline and distilled water injection in painful sacrum on back pain in first stage of labor.
METHODS: This randomized clinical trial study was done on 140 volunteers who were selected by simple sampling method and then randomly allocated to two groups, 70 participants in case and 70 participants in control. Four areas selected on sacrum for injection of distilled water (0.1 cc) and saline normal (0.1 cc). Then, in the 10th, 30th, 45th, 90th minutes of post injections, pain was estimated in both groups by VAS method which is a standard scale. Data was analyzed by paired t- test, X2 and t–student.
FINDINGS: Mean pain was not significant in 2 groups in the 10th, 30th minutes. Mean of preinjection of saline normal was 54.5±34.1 which showed a significant difference with post injection in the 45th minute (61.1±29.5, p=0.02) and, in the 90th minute (65.3±32.1, p=0.01). Mean of preinjection of distilled water was 54.5±33.2 which was significant with post injection in the 45th minute (58.2±29.5, p=0.02) and in the 90th minute (64.1±30.9, p=0.006).
CONCLUSION: Data showed that subcutaneous injection of distilled water and normal saline in sacral area did not increase and decrease pain significantly up to 30 minutes, but after 30 minutes, the pain in both two groups increased that the injection frequency may cause a better results. |
