A Model Practice Template for Hydrotherapy in Labor and Birth

Women's experiences of waterbirth: A systematic review with narrative synthesis

BACKGROUND

Childbirth is a major event in a woman's life, shaped by various factors including the individual's circumstances, the birth process, the care provided, social support, and immediate post-birth experiences. Although waterbirth has become increasingly popular in recent years, research on women's experience remains limited. This review aims to synthesize evidence on women's experiences of waterbirths to inform clinical guidelines, support personalized care, and identify priorities for future research.

METHODS

This study was a systematic review, with searches conducted across three databases (CINAHL, Scopus, and PubMed) covering 2013 to 2023. A total of 17 studies met the inclusion criteria, and the data were analyzed through a narrative synthesis approach.

FINDINGS

Eight categories were identified that capture women's experiences with waterbirth. Women who give birth in water often feel a strong sense of control, describing the experience as empowering, intimate, and relaxing. They value the ease of changing positions in the birthing pool, although some find the pool's design challenging and occasionally uncomfortable. Overall, water is widely regarded as an effective pain relief method and a natural, positive childbirth option, though it can also evoke negative emotions. The roles of both the partner and midwife are essential, and women generally report positive experiences following a waterbirth.

CONCLUSION

Most women were satisfied with waterbirth. However, further research is needed to understand waterbirth's impact on women's psychological well-being, as well as the perspectives of partners and midwives. Additionally, cultural perceptions and effective ways to provide comprehensive information to support expectant mothers in their decision-making require further exploration.

Spiritual Experiences of Portuguese Women Who had a Water Birth

This study aimed to understand the significance of spirituality to Portuguese women who had a water birth. In-depth interviews, using a semi-structured questionnaire, were conducted with 24 women who experienced water birth at the hospital or home. Results were analyzed from a narrative interpretation perspective. Three spirituality-related categories emerged: (1) Beliefs and connections with the body; (2) Spirituality: integration of being a woman and transformation during birth; and (3) Spirituality as wisdom, intuition, or the sixth sense. Spirituality was perceived in women's faith and beliefs in a superior being that helped them manage the unpredictability and uncontrollability of giving birth.

Alternate Birth Strategies

Community birth is defined as birth that occurs outside the hospital setting. Birthing in a birth center can be safe for certain patient populations. Home birth can also be safe in well-selected patient with a well-established transfer infrastructure should an emergency occur. Unfortunately, many areas of the United States and the world do not have this infrastructure, limiting access to safe community birth. Immersion during labor has been associated with decreased need for epidural and pain medication. Delivery should not occur in water due to concerns for infection and cord avulsion. Umbilical cord non-severance (also called lotus birth) and placentophagy should be counseled against due to well-documented risks without clear benefit. Birth plans and options should be regularly discussed during pregnancy visits.

Quantitative cardiac autonomic outcomes of hydrotherapy in women during the first stage of labor

Introduction

Most hydrotherapy studies during childbirth report findings related to pain using a widespread set of subjective measures. In this study, ECG biomarkers as quantitative cardiac autonomic outcomes were used to assess the effects of warm shower hydrotherapy on laboring women during the first stage of labor.

Methods

This was a prospective single-blind cohort study on stage I delivering women. Their cardiac autonomic function was assessed using heart rate variability (HRV) measures during a deep breathing test using point-of-care testing comprised of an HRV scanner system with wireless ECG enabling real-time data analysis and visualization. Labor pain and anxiety were assessed using the Visual Analog Scale for Pain (VASP) and the Beck Anxiety Inventory (BAI). A total of 105 pregnant women in the first stage of labor who received warm shower hydrotherapy, intravenous analgesia (scopolamine + sodium dipyrone), or spinal anesthetic (bupivacaine + morphine) were enrolled.

Results

In women during the first stage of labor, parasympathetic modulation reflected through RMSSD (root mean square of successive RR interval differences) was significantly reduced by hydrotherapy and intravenous analgesia (before vs. after mean rank diff. 35.73 and 65.93, respectively, p < 0.05). Overall HRV (SDNN, standard deviation of RR intervals) was significantly decreased only by intravenous analgesia (before vs. after mean rank diff. 65.43, p < 0.001). Mean heart rate was significantly increased by intravenous analgesia, while spinal anesthesia reduced it, and hydrotherapy did not alter it (before vs. after mean rank diff. -49.35*, 70.38*, -24.20 ^NS , respectively, *p < 0.05, ^NS not significant).

Conclusion

This study demonstrates that warm shower therapy may impact the sympathovagal balance via parasympathetic withdrawal in women during the initial stage of labor. The findings of this study provide quantitative support for using warm shower hydrotherapy during labor via point-of-care testing. The dependability of hydrotherapy as a non-pharmacological treatment is linked to the completion of more clinical research demonstrating quantitative evidence via outcome biomarkers to support indications on stress and birth progress.

Maternal and neonatal outcomes following waterbirth: a cohort study of 17 530 waterbirths and 17 530 propensity score-matched land births

OBJECTIVE

Investigate maternal and neonatal outcomes following waterbirth.

DESIGN

Retrospective cohort study, with propensity score matching to address confounding.

SETTING

Community births, United States.

SAMPLE

Medical records-based registry data from low-risk births were used to create waterbirth and land birth groups (n = 17 530 each), propensity score-matched on >80 demographic and pregnancy risk covariables.

METHODS

Logistic regression models compared outcomes between the matched waterbirth and land birth groups.

MAIN OUTCOME MEASURES

Maternal: immediate postpartum transfer to a hospital, any genital tract trauma, severe (3rd/4th degree) trauma, haemorrhage >1000 mL, diagnosed haemorrhage regardless of estimated blood loss, uterine infection, uterine infection requiring hospitalisation, any hospitalisation in the first 6 weeks. Neonatal: umbilical cord avulsion; immediate neonatal transfer to a hospital; respiratory distress syndrome; any hospitalisation, neonatal intensive care unit (NICU) admission, or neonatal infection in the first 6 weeks; and neonatal death.

RESULTS

Waterbirth was associated with improved or no difference in outcomes for most measures, including neonatal death (adjusted odds ratio [aOR] 0.56, 95% CI 0.31-1.0), and maternal or neonatal hospitalisation in the first 6 weeks (aOR 0.87, 95% CI 0.81-0.92 and aOR 0.95, 95% CI 0.90-0.99, respectively). Increased morbidity in the waterbirth group was observed for two outcomes only: uterine infection (aOR 1.25, 95% CI 1.05-1.48) (but not hospitalisation for infection) and umbilical cord avulsion (aOR 1.57, 95% CI 1.37-1.82). Our results are concordant with other studies: waterbirth is neither as harmful as some current guidelines suggest, nor as benign as some proponents claim.

TWEETABLE ABSTRACT

New study demonstrates #waterbirth is neither as harmful as some current guidelines suggest, nor as benign as some proponents claim. @TheUpliftLab @BovbjergMarit @31415926abc @NICHD_NIH.

A retrospective comparison of waterbirth outcomes in two United States hospital settings

BACKGROUND

Water immersion during labor is an effective comfort measure; however, outcomes for waterbirth in the hospital setting have not been well documented. Our objective was to report the outcomes from two nurse-midwifery services that provide waterbirth within a tertiary care hospital setting in the United States.

METHODS

This study is a retrospective, observational, matched comparison design. Data were collected from two large midwifery practices in tertiary care centers using information recorded at the time of birth for quality assurance purposes. Land birth cases were excluded if events would have precluded them from waterbirth (epidural, meconium stained fluid, chorioamnionitis, estimated gestational age < 37 weeks, or body mass index > 40). Neonatal outcomes included Apgar score and admission to the neonatal intensive care unit. Maternal outcomes included perineal lacerations and postpartum hemorrhage.

RESULTS

A total of 397 waterbirths and 2025 land births were included in the analysis. There were no differences in outcomes between waterbirth and land birth for Apgar scores or neonatal intensive care admissions (1.8% vs 2.5%). Women in the waterbirth group were less likely to sustain a first- or second-degree laceration. Postpartum hemorrhage rates were similar for both groups. Similar results were obtained using a land birth subset matched on insurance, hospital location, and parity using propensity scores.

DISCUSSION

In this study, waterbirth was not associated with increased risk to neonates, extensive perineal lacerations, or postpartum hemorrhage. Fewer women in the waterbirth group sustained first- or second-degree lacerations requiring sutures.

The Experience of Land and Water Birth Within the American Association of Birth Centers Perinatal Data Registry, 2012-2017

Consumer demand for water birth has grown within an environment of professional controversy. Access to nonpharmacologic pain relief through water immersion is limited within hospital settings across the United States due to concerns over safety. The study is a secondary analysis of prospective observational Perinatal Data Registry (PDR) used by American Association of Birth Center members (AABC PDR). All births occurring between 2012 and 2017 in the community setting (home and birth center) were included in the analysis. Descriptive, correlational, and relative risk statistics were used to compare maternal and neonatal outcomes. Of 26 684 women, those giving birth in water had more favorable outcomes including fewer prolonged first- or second-stage labors, fetal heart rate abnormalities, shoulder dystocias, genital lacerations, episiotomies, hemorrhage, or postpartum transfers. Cord avulsion occurred rarely, but it was more common among water births. Newborns born in water were less likely to require transfer to a higher level of care, be admitted to a neonatal intensive care unit, or experience respiratory complication. Among childbearing women of low medical risk, personal preference should drive utilization of nonpharmacologic care practices including water birth. Both land and water births have similar good outcomes within the community setting.

Systematic Review of Case Reports of Poor Neonatal Outcomes With Water Immersion During Labor and Birth

Water immersion is a valuable comfort measure in labor, that can be used during the first or second stage of labor. Case reports of adverse outcomes create suspicion about water birth safety, which restricts the availability of water birth in the United States. The objective of this study was to synthesize the information from case reports of adverse water birth events to identify practices associated with these outcomes, and to identify patterns of negative outcomes. The research team conducted a systematic search for cases reports of poor neonatal outcomes with water immersion. Eligible manuscripts reported any adverse neonatal outcome with immersion during labor or birth; or excluded if no adverse outcome was reported or the birth reported was unattended. A qualitative narrative synthesis was conducted to identify patterns in the reports. There were 47 cases of adverse outcomes from 35 articles included in the analysis. There was a pattern of cases of Pseudomonas and Legionella, but other infections were uncommon. There were cases of unexplained neonatal hyponatremia following water birth that need further investigation to determine the mechanism that contributes to this complication. The synthesis was limited by reporting information of interest to pediatricians with little information about water birth immersion practices. These data did not support concerns of water aspiration or cord rupture, but did identify other potential risks. Water immersion guidelines need to address infection risk, optimal management of compromised water-born infants, and the potential association between immersion practice and hyponatremia.

Outcomes of Waterbirth in a US Hospital-Based Midwifery Practice: A Retrospective Cohort Study of Water Immersion During Labor and Birth

INTRODUCTION

Although the safety of water immersion during labor is largely supported by evidence from research, the risks to women and neonates during waterbirth are not well established. The purpose of this study was to generate evidence regarding maternal and neonatal outcomes related to water immersion in labor and during birth.

METHODS

A retrospective cohort study included a convenience sample of women receiving prenatal care at a nurse-midwifery practice. Participants were categorized into 3 groups: 1) waterbirth, 2) water labor, or 3) neither. Participant characteristics, maternal outcomes, and newborn outcomes were collected at time of birth and health record abstraction. At the 6-week postpartum visit, another maternal outcome, satisfaction with birth, was measured using the Care in Obstetrics: Measure for Testing Satisfaction (COMFORTS) scale. Analysis included effect size, descriptive statistics (sample characteristics), and maternal and neonatal group differences (analysis of variance and chi-square) with a significance level of P < .05.

RESULTS

Women in the waterbirth (n = 58), water labor (n = 61), and neither (n = 111) groups were primarily white, married, and college educated and did not differ by age or education. Women in the waterbirth group were more likely to be multiparous. Nulliparous women who had a waterbirth had a significantly shorter second stage of labor than nulliparous women who did not have a waterbirth (P = .03). The most commonly cited reasons for discontinuation of hydrotherapy were maternal choice (42.6%) and need for pain medication (29.5%). Significantly more women in the waterbirth group experienced a postpartum hemorrhage, compared with water labor or neither (n = 5, n = 3, n = 1, respectively; P = .045); there was no difference in related clinical measures. Neonatal outcomes were not significantly different. Maternal satisfaction was high across all groups.

DISCUSSION

The results of this study suggest that waterbirth, attended by qualified intrapartum care providers in hospital settings in the United States, is a reasonable option for low-risk women and their neonates.

Culture, bathing and hydrotherapy in labor: An exploratory descriptive pilot study

OBJECTIVE

Though bathing (hydrotherapy) is widely used during labor to decrease anxiety and pain and to promote relaxation, the influence of cultural beliefs about bathing by parturients is virtually unknown. This pilot study explored pregnant women's experiences of bathing, bathing in labor, and cultural beliefs about bathing.

DESIGN

An exploratory, descriptive design.

SETTING

Low risk obstetrical clinics.

PARTICIPANTS

Healthy Hispanic, Black, White, American-Indian and Asian women (N = 41) at >37 weeks gestation.

METHODS

During a routine prenatal visit women responded to a brief openended questionnaire on the use of bathing. Data was captured using a modified ethnographic method involving observation and note taking with thematic analysis and quantification of percent response rates.

FINDINGS

Forty-six percent (N = 41) of women used bathing for purposes other than hygiene but only 4.9% (N = 41) of these women bathed during a previous labor. The women described bathing as relaxing, easing, calming, and efficacious for relief of menstrual cramps and labor contractions. Ten percent of women reported cultural beliefs about bathing.

CONCLUSIONS

Women who bathe, report relief of anxiety, menstrual and labor pain and promotion of mental and physical relaxation. The findings do not support the view that bathing is associated with identifiable cultural beliefs; rather, they suggest that bathing is a self-care measure used by women. This practice is likely transmitted from generation to generation by female elders through the oral tradition. Assumptions that race or ethnicity precludes the use of bathing may be faulty. Cautionary instructions should be given to pregnant women who are <37 completed weeks of gestation, to avoid bathing for relief of cramping or contractions and to seek immediate health care evaluation. Study of culturally intact groups may uncover additional themes related to bathing in labor and as a self-care measure for dysmenorrhea.

Systematic Review of Hydrotherapy Research: Does a Warm Bath in Labor Promote Normal Physiologic Childbirth?

Health sciences research was systematically reviewed to assess randomized controlled trials of standard care versus immersion hydrotherapy in labor before conventional childbirth. Seven studies of 2615 women were included. Six trials examined hydrotherapy in midwifery care and found an effect of pain relief; of these, 2 examined analgesia and found reduced use among women who bathed in labor. One study each found that hydrotherapy reduced maternal anxiety and fetal malpresentation, increased maternal satisfaction with movement and privacy, and resulted in cervical dilation progress equivalent to standard labor augmentation practices. Studies examined more than 30 fetal and neonatal outcomes, and no benefit or harm of hydrotherapy was identified. Two trials had anomalous findings of increased newborn resuscitation or nursery admission after hydrotherapy, which were not supported by additional results in the same or other studies. Review findings demonstrate that intrapartum immersion hydrotherapy is a helpful and benign practice. Hydrotherapy facilitates physiologic childbirth and may increase satisfaction with care. Maternity care providers are recommended to include hydrotherapy among routine labor pain management options and consider immersion to promote progress of normal or protracted labor, particularly among women with preferences to avoid obstetric medications and procedures.
