IntroductionImmersion in water is a non-pharmacological method for pain relief during childbirth. The aim was to describe the experiences, values and preferences of women regarding water immersion during childbirth identified in the evidence.MethodsA systematic review and thematic synthesis of qualitative evidence was conducted. Databases were searched from 2009 to 2022 and screened for inclusion using pre-determined criteria. Studies that used qualitative methods for data collection and analysis to investigate the opinions of women or health professionals in hospital settings were included. Non-qualitative studies, mixed methods studies that did not separately report qualitative findings and studies in languages other than English or Spanish were excluded. The Critical Appraisal Skills Programme Qualitative Research Checklist was used to assess study quality and findings were synthesized using thematic synthesis, as described by Thomas and Harden.The final report was reviewed by several categories of health professionals that care for mothers and infants, as well women.ResultsThirteen studies met inclusion criteria and were included in this review. Nine studies have been identified that reflect the experience of women in relation to immersion in water during childbirth, a study exploring the factors that determine the use of immersion during childbirth according to the point of view of both women and midwives, and three more studies on midwives’ experience with water immersion during childbirth. In the qualitative studies the following key themes emerged: Reasons identified by the women/professionals for choosing a water birth, benefits experienced in water births and barriers and facilitators of immersion in water during childbirth.ConclusionsThe evidence from qualitative studies indicates that women associated water birth with a sense of autonomy and control over labor, and a lower level of associated pain. Further, a water birth was considered a positive experience. From the point of view of midwives, to make water births safe, there is a need for adequate resources, as well as rigorous standardized protocols.
