The Effects of Water Immersion during First Stage of Labor on Postpartum Systemic Inflammatory Response

Abstract

Abstract Objective The systemic inflammatory response is a cascade of physiologic reactions that arise in response to trauma, infection, burn, or any kind of injury. This study aimed to determine the effects of water immersion during the first stage of labor on the systemic inflammatory indices in the postpartum period. Materials and methods In this retrospective study, 125 healthy multiparous women with uncomplicated pregnancies between 37 and 41 weeks of gestation who elected for immersion in water during the first stage of labor were compared with multiparous uncomplicated term women who had conventional vaginal births on land (n=125). Age, parity, body mass index (BMI), gestational age, duration of labor, birth weight, Apgar scores, neonatal intensive care unit admissions, and ante- and postpartum whole blood parameters were noted. Antepartum and postpartum neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) were calculated for all patients as systemic inflammatory indices. Results Demographic characteristics and birth outcomes of both groups were similar except BMI, which was statistically significantly higher in the water immersion group. There were no statistical differences in antepartum NLR, MLR, PLR, and MPV between the 2 groups. However, postpartum NLR, MLR, PLR, and MPV were statistically significantly lower in the water immersion group compared to the controls. Conclusion Water immersion during the first stage of labor might decrease systemic inflammatory indices in the early postpartum period.
