Background & aim: Stimulation of labor pain is one of the most common and necessary procedures in midwifery. Delivery is induced to accelerate the delivery process in more than 15% of pregnancies. In this study, two labor induction methods, including Foley catheter insertion and hot water shower, were compared with natural vaginal delivery. Methods: A clinical trial study was conducted on 150 nulliparous pregnants at gestational weeks of 40-41. Patients were divided into three groups randomly. Groups 1, 2, and 3 were performed using catheterization, warm shower, and routine delivery, respectively. All patients went under Induction using oxytocin after the performance. Descriptive-analytical tests were used to assess the progress of labor using SPSS/v16. Results: The mean age in the three groups were 24.70±11.43, 24.19±10.23 and 23.92±10.30 years, respectively (p=0.728). The slow progression of labor in the first and second groups and the postdate delivery in the third group were the most common causes of induction. There were no significant differences in the pain intensity of uterine contractions between groups before intervention (p<0.169). After the intervention, the pain intensity was increased in all groups significantly (p<0.001). The highest and lowest increases in pain were seen in induction (2.08) and hot water shower (0.03) groups, respectively. The shortest time between contraction and complete dilation of the cervix was revealed in the first group (p<0.001). Normal deliveries leading to the Cesarean operation had the highest rate in the third group (p=0.266). Conclusion: It seems that Foley's catheter insertion has a positive effect on the process of delivery as well as the warm shower bath reduces the pain of patients during the delivery process.
