Intradermal sterile water injections for the relief of low back pain in labour -- a systematic review of the literature

OBJECTIVE: To search literature published on the administration of intradermal sterile water injections to women in labour who experience severe low back pain, and to critically evaluate the evidence for therapeutic merit. METHOD: A systematic review of six randomised controlled trials from countries including Canada, Denmark, Iran, Sweden and Thailand was conducted. RESULTS: Statistically significant findings (p<0.0001) of relief of low back pain in labour lasting from 10 min to 2 h post-administration. CONCLUSION: Intradermal injections of sterile water possess powerful analgesic benefits for women experiencing low back pain in labour and their use in this therapeutic setting is justifiable.     

A comparison of two versus four sterile water injections for the relief of back pain in labour: A multicentre randomised equivalence trial

BackgroundRecent trials demonstrated the safety and efficacy of sterile water injections to provide relief from labour back pain. While four injections is the most common approach variations in technique, such as employing two injections, are also used.AimTo determine if the analgesic effect of two sterile water injections is clinically equivalent to four.Methods238 women in labour with a Visual Analogue Scale pain score (VAS) of 70 millimetres (mm) (0 = no pain; 100 = worst pain imaginable) were randomised to two or four sterile water injections. The primary outcome was pain measured on a VAS at 30 min post treatment. A priori margin of equivalence was set at ±10 mm. Secondary outcomes included the likelihood of achieving an at least 30% and 50% reduction in pain, birth and neonatal outcomes.ResultsAt 30 min post-injection the difference in VAS scores between the techniques was ?5.97 (95% Confidence Interval [CI] ?13.18–1.22). As the lower end of the CI exceeds the margin of ?10 mm equivalence was not demonstrated. Both techniques achieved an at least 30% reduction in pain in over 75% of participants though duration of effect was longer in the four injection group. There was no difference in other birth related secondary outcomes.ConclusionFour injections provided a margin of benefit over two injections in level and duration of analgesia.DiscussionFour injections remains the technique of choice though two injections still provided significant pain relief and would be suitable where it was not possible or desirable to provide four.     

Australian midwives views and experiences of practice and politics related to water immersion for labour and birth: A web based survey

Background

There is little published research that has examined practitioners’ views and experiences of pain relieving measures commonly used during labour and birth, particularly for non-pharmacological measures such as water immersion. Furthermore, there is minimal published research examining the process of policy and guideline development, that is, the translation of published research to usable practice guidance.

A critical analysis of Australian policies and guidelines for water immersion during labour and birth

Background

Accessibility of water immersion for labour and/or birth is often dependent on the care provider and also the policies/guidelines that underpin practice. With little high quality research about the safety and practicality of water immersion, particularly for birth, policies/guidelines informing the practice may lack the evidence necessary to ensure practitioner confidence surrounding the option thereby limiting accessibility and women’s autonomy.

Chronic pain,pain severity and analgesia use in Australian women of reproductive age

Background

The increasing prevalence and adverse outcomes associated with opioid analgesia use in women of reproductive age have become a significant public health issue internationally, with use during pregnancy potentially affecting maternal and infant health outcomes.

Pain relief for childbirth: The preferences of pregnant women,midwives and obstetricians

ObjectiveTo compare the personal preferences of pregnant women, midwives and obstetricians regarding a range of physical, psychosocial and pharmacological methods of pain relief for childbirth.MethodSelf-completed questionnaires were posted to a consecutive sample of 400 pregnant women booked-in to a large tertiary referral centre for maternity care in South Australia. A similar questionnaire was distributed to a national sample of 500 obstetricians as well as 425 midwives at: (1) the same hospital as the pregnant women, (2) an outer-metropolitan teaching hospital and (3) a district hospital. Eligible response rates were: pregnant women 31% (n = 123), obstetricians 50% (n = 242) and midwives 49% (n = 210).FindingsOverall, midwives had a greater personal preference for most of the physical pain relief methods and obstetricians a greater personal preference for pharmacological methods than the other groups. Pregnant women's preferences were generally located between the two care provider groups, though somewhat closer to the midwives. All groups had the greatest preference for having a support person for labour with more than 90% of all participants wanting such support. The least preferred method for pregnant women was pethidine/morphine (14%).ConclusionThere are differences in the personal preferences of pregnant women, midwives and obstetricians regarding pain relief for childbirth. It is important that the pain relief methods available in maternity care settings reflect the informed preferences of pregnant women.     

Perceptions of paternal involvement and labour pain management in Chinese couples during childbirth: A qualitative study

BackgroundLabour pain is an individual experience embedded in a socio-cultural context. In childbirth, the father’s involvement provides important support to the mother during labour. However, few published studies have evaluated couples’ experiences of paternal involvement and labour pain management in the Chinese context.AimThis study aimed to understand the experience of labour pain management and the father’s involvement in childbirth from the perspectives of women and their partners in Hong Kong.MethodsAn exploratory qualitative design was adopted. A purposive sample of 45 Chinese parents was recruited at the postnatal unit of a regional hospital. Data were collected through semi-structured face-to-face interviews within 1 month after birth. The data were subjected to content analysis.FindingsThe findings revealed six major themes: the mothers’ experience of labour pain, effectiveness of pain relief measures, mothers’ perceptions of support from their partners, mothers’ perceptions of support from healthcare professionals, fathers’ experience of involvement in childbirth and suggested improvements to maternity services.DiscussionChinese mothers experienced intense labour pain and used various pain relief measures. Both parents considered the involvement of fathers and support from healthcare professionals to be highly significant during childbirth.ConclusionsThis study highlights the need for a family-centred model of care during childbirth that involves both parents in the decision-making process. Chinese maternity services should implement individualised birth plans that acknowledge both parents’ expectations and preferences, thus promoting a positive childbirth experience for the parents.     

Key indicators influencing management of prolonged second stage labour by midwives in freestanding birth centres: Results from an ethnographic interview study

ProblemsComplications for newborns and postpartum clients in the hospital are more frequent after a prolonged second stage of labour. Midwives in community settings have little research to guide management in their settings.AimWe explored how US birth centre midwives identify onset of second stage of labour and determine when to transfer clients to the hospital for prolonged second stage.MethodsEthnographic interviews of midwives with at least 2 years’ experience in birth centres and participant observation of birth centre care.FindingsWe interviewed 21 midwives (18 CNMs, 3 CPMs/equivalent) from 18 birth centres in 11 US states, 45% with hospital practice privileges. Midwives relied on and engaged in embodied practice in evaluating each labour and making decisions concerning management of labour. Midwives considered time a useful but limited measure as a guiding factor in management. Though ideas of time and progress do play an important role in the decision-making process of midwives, their usefulness is limited due to the continual, multifactorial, and multisensory nature of the assessment. Relationship with the transfer hospital structured midwives’ decision-making about transfers.Discussion & conclusionThese findings can inform future robust multivariate evaluation of factors, including but not limited to time, in guidelines for management of second stage of labour. Optimal management may require formal consideration of more than just time and parity. Our findings also suggest the need for evaluation of how structural issues involving hospital privileges for midwives and relationships between birth centre and hospital staff affect the well-being of childbearing families.     

The experiences of privately practising midwives in Australia who have been reported to the Australian Health Practitioner Regulation Agency: A qualitative study

BackgroundIn Australia the majority of homebirths are attended by privately practising midwives (PPMs). In recent years PPMs have been increasingly reported to the Australian Health Practitioner Regulation Agency (AHPRA) mostly by other health professionals.Purposeto explore the experiences of PPMs in Australia who have been reported to the AHPRA.MethodsA qualitative interpretive approach, employing in-depth interviews with eight PPMs was undertaken and analysed using thematic analysis. A feminist theoretical framework was used to underpin the research.ResultsThe majority of reports made to AHPRA occurred when midwives supported women who chose care considered outside the recommended Australian College of Midwives (ACM) Consultation and Referral Guidelines. During data analysis an overarching theme emerged, “Caught between women and the system”, which described the participants’ feelings of working as a PPM in Australia. There were six themes and several sub-themes: The suppression of midwifery, A flawed system, Lack of support, Devastation on so many levels, Making changes in the aftermath and Walking a tight rope forever. The findings from this study reveal that midwives who are under investigation suffer from emotional and psychological distress. Understanding the effects of the process of investigation is important to improve the quality of professional and personal support available to PPMs who are reported to AHPRA and to streamline processes.ConclusionIt is becoming increasingly difficult for PPMs to support the wishes and needs of individual women and also meet the requirements of the regulators, as well as the increasingly risk averse health service.
