Pak J Med Sci Jan ;26(3):551-4.

Objective: To assess the effects of delivery in water, as a normal way of delivery without intervention, in reducing the pain and duration of delivery. Methodology: This is a clinical trial studying a community of Gravida one and two pregnant women at the gestational age of 38-42 weeks, referred to Asalian hospital. The sample volume was 100 cases, equally divided in two groups of routine delivery and delivery in water. The pain and duration of delivery were analyzed using K-square, Kruskal-wiallis, and mann whitney, with pv<0.05 considered significant. Results: The findings show that the average duration of active delivery was 3.1 hrs ± 0.8 in the delivery in water group, significantly lower than that of the other group, that is, 4.7 hrs ± 0.8 (p<0.05). Also the average of the second phase of delivery was 0.53 hrs ± 0.22 in the delivery in water group, significantly lower than that of the routine group, that is, 0.88 hrs ± 0.43 (p<0.05). The amount of pain was measured in both groups using the visual analog score, yielding 3.53 ± 0.79 in delivery in water, and 6.9 ± 1.7 in the other group, which indicates a significant decrease in pain in delivery in water (p<0.05). Conclusion: This study indicates that delivery in water may be a suitable, nonmedical, and non invasive alternative, because it reduces the pain and duration of delivery.
