Effectiveness of acupuncture-type interventions versus expectant management to correct breech presentation: A systematic review

YouTube™ as a Source of Information on Acupuncture for Correction of Breech Presentation

BACKGROUND AND AIM

Breech presentation is a condition that occurs in rare cases in pregnancy. Although guidelines recommend a cesarian section or an external cephalic version in case of breech, alternative procedures like acupuncture, are also available. Information on this approach is mostly found by patients through social media; we aimed to study content quality and the reliability of information present on YouTube™ (Google LLC, Mountain View, California, United States), one of the most popular.

METHODS

Two gynecologists and an anesthesiologist, who was qualified as an acupuncturist, rated the reliability and the content quality of 23 of the first 100 results from YouTube. Normal data distribution was tested with the Shapiro-Wilk test. General features of videos, reliability, and content quality were compared with the Wilcoxon-Mann-Whitney test (continuous variables) and the Chi-square test (categorical variables). All tests were two-sided, and the statistical significance level was determined at p<0.05.

RESULTS

Concerning reliability, all videos were rated poorly while only one was judged as sufficiently high in quality content. Lower scores in terms of reliability and content quality resulted from the reviewers' evaluation with no videos reported as suggestable to patients. Two videos were considered fit to be suggested to patients by the gynecologist reviewers.

CONCLUSIONS

Information about the role and the success rate of acupuncture for converting breech presentation found on YouTube are poorly reliable, low-quality, and not valid for patients. It should be a physician's duty to provide correct information to patients.

Respectful maternity care in the UK using a decolonial lens

Respectful maternity care (RMC) is part of a global movement addressing the previous absence of human rights in global safe maternal care guidance. RMC is grounded in kindness, compassion, dignity and respectful working conditions. The decolonisation movement in healthcare seeks to dismantle structural biases set up from a historically white, male, heteronormative Eurocentric medical system. This article applies a decolonising lens to the RMC agenda and examines barriers to its implementation in UK healthcare systems. Searches of peer-reviewed journals about decolonising maternity care in the UK revealed little. Drawing from wider information bases, we examine power imbalances constructed throughout a history of various colonial biases yet lingering in maternity care. The overarching findings of our analysis revealed 3 areas of focus: professional structures and institutional biases; power imbalances between types of staff and stakeholders of care; and person-centred care through a decolonial lens. To uproot inequity and create fairer and more respectful maternity care for women, birthing people and staff, it is vital that contemporary maternity institutions understand the decolonial perspective. This novel enquiry offers a scaffolding to undertake this process. Due to significant differences in colonial history between Western colonising powers, it is important to decolonise with respect to these different territories, histories and challenges.

Effect of acupressure at the BL67 spot on the spontaneous rotation of fetus with breech presentation: A randomized controlled trial

BACKGROUND

Breech is a common fetal presentation in preterm pregnancies. This study aimed to investigate the effect of acupressure at the BL67 point on the spontaneous rotation of fetus with breech presentation.

METHODS

An unblind, two-armed randomized controlled trial was carried out from September 2017 to April 2020. Research participants were 138 pregnant women at 32 to 35 weeks of gestational age that had fetal breech presentation confirmed by ultrasound. They were randomly assigned into intervention and control groups (n=69 in each group). The intervention group received acupressure at the BL67 point on both feet for 10 minutes daily and for two consecutive weeks. The control group received routine care. Demographic and midwifery data questionnaires were used for data collection.

RESULTS

The spontaneous rotation of fetus with breech presentation into cephalic was observed in the majority of participants in the intervention group (82.6%) compared to the control group (17.4%) (p<0.001). Statistically significant differences in the fetal presentation at delivery was observed between the groups (84.1% cephalic vs. 18.8% breech, p<0.001). Regarding the type of delivery, cesarean section was reported mostly (85.5%) in the control group compared to the intervention group (21.7%) (p<0.001). However, the first- and fifth-minute Apgar scores of newborns had no statistically significant differences between the groups (p=0.773).

CONCLUSION

It is suggested to incorporate acupressure at the BL67 point into the care process for pregnant women to help with the reduction of the rate of cesarean section and avoid its related complications.

Birth preparation acupuncture for normalising birth: An analysis of NHS service routine data and proof of concept

A number of studies show that acupuncture may help with labour and delivery. An NHS maternity acupuncture service providing birth preparation acupuncture has assessed its routine hospital maternity annual data from 2014 to 2016 to see what effect it had on labour and delivery outcomes. The data from this service was analysed and women who had birth preparation acupuncture were compared with those who did not receive it. Maternal age, parity and socio-economic status were considered confounders and were adjusted for in the analysis. Women who received acupuncture had more normal births (less surgical births) [OR 0.76 (0.64, 0.91)], required less intrapartum analgesia [OR 0.74 (0.63, 0.86)], fewer components of an induction of labour [OR 0.74 (0.61, 0.91)] and a reduced length of a hospital stay [OR 0.91 (0.87, 0.95)]. The patients highly valued the availability of acupuncture within the maternity service as it enhanced their patient journey.Impact statementWhat is already known on this subject? Numerous studies provide evidence for the effects of acupuncture in normalising pregnancy and birth. These effects include musculoskeletal preparation of the pelvis, cervical ripening, enhancing endogenous oxytocin release, and analgesic properties.What do the results of this study add? Our analysis shows that women who received birth preparation acupuncture had fewer surgical births, required less intrapartum analgesia, less components of induction of labour and had a reduced length of hospital stay, supporting the use of maternity acupuncture in normalising birth outcomes.What are the implications of these findings for clinical practice and/or further research? The findings show that acupuncture, by potentially normalising birth, may lead to reductions in costs of service. Further, additional research is required to see whether acupuncture is cost effective and could have an adjunctive role as a complementary therapy for improving birth outcomes and a woman's experience of childbirth.

Effectiveness and Safety of Acupuncture and Moxibustion in Pregnant Women with Noncephalic Presentation: An Overview of Systematic Reviews

Background

Breech presentation at the time of delivery is 3.8–4%. Fetuses that maintain a noncephalic presentation beyond 32 weeks will have a lower probability of spontaneous version before labor. Given the increasing interest in exploring the use of complementary medicine during pregnancy and childbirth, the moxibustion technique, a type of traditional Chinese medicine, could be another option to try turning a breech baby into a cephalic presentation.

Objectives

To review the evidence from systematic reviews (SR) on the efficacy and safety of acupuncture and moxibustion in pregnant women with noncephalic presentation.

Main Results

Our SR synthesizes the results from five clinical trials on pregnant women with a singleton noncephalic presentation. There is evidence that moxibustion reduces the number of noncephalic presentations at the time of birth compared with no treatment. The adverse effects that acupuncture and moxibustion can cause seem to be irrelevant. Most SRs agree that there are no adverse effects directly related to acupuncture and moxibustion.

Conclusions

Even though the results obtained are positive and the five reviews conclude that moxibustion reduces the number of noncephalic presentations at birth (alone or combined with postural techniques or acupuncture), there is considerable heterogeneity between them. Better methodologically designed studies are required in the future to reaffirm this conclusion.

Antenatal and intrapartum interventions for reducing caesarean section, promoting vaginal birth, and reducing fear of childbirth: An overview of systematic reviews

Concern has been expressed globally over rising caesarean birth rates. Recently, the International Federation of Gynaecology and Obstetrics (FIGO) called for help from governmental bodies, professional organisations, women’s groups, and other stakeholders to reduce unnecessary caesareans. As part of a wider research initiative, we conducted an overview of systematic reviews of antenatal and intrapartum interventions, and reports of evidence based recommendations, to identify and highlight those that have been shown to be effective for reducing caesarean birth, promoting vaginal birth and reducing fear of childbirth. Following registration of the review protocol, (PROSPERO 2018 CRD42018090681), we searched The Cochrane Database of Systematic Reviews, PubMed, CINAHL and EMBASE (Jan 2000-Jan 2018) and searched for grey literature in PROSPERO, and on websites of health professional and other relevant bodies. Screening and selection of reviews, quality appraisal using AMSTAR-2, and data extraction were performed independently by pairs of at least two reviewers. Excluding reviews assessed as ‘critically low’ on AMSTAR-2 (n = 54), 101 systematic reviews, and 10 reports of evidence based recommendations were included in the overview. Narrative synthesis was performed, due to heterogeneity of review methodology and topics. The results highlight twenty-five interventions, across 17 reviews, that reduced the risk of caesarean, nine interventions across eight reviews that increased the risk of caesarean, eight interventions that reduced instrumental vaginal birth, four interventions that increased spontaneous vaginal birth, and two interventions that reduced fear of childbirth. This overview of reviews identifies and highlights interventions that have been shown to be effective for reducing caesarean birth, promoting vaginal births and reducing fear of childbirth. In recognising that clinical practices change over time, this overview includes reviews published from 2000 onwards only, thus providing contemporary evidence, and a valuable resource for clinicians when making decisions on practices that should be implemented for reducing unnecessary caesarean births safely.

Turning Foetal Breech Presentation at 32-35 Weeks of Gestational Age by Acupuncture and Moxibustion

Introduction

Foetal breech presentation is an obstetric problem that often leads to caesarean section. Stimulation of the acupoint BL67 by moxibustion may correct breech presentation.

Methods

We observed 93 pregnant women in the 32nd-35th week of gestation with normal pregnancy and ultrasound diagnosis of breech presentation. The patients received stimulation of acupoint BL67 by self-administered moxibustion once a day for two weeks and if foetuses still were in breech presentation, moxibustion, and needle in the points BL65 and SI1, lasting 30 minutes, for three days in one week. The main outcome was vaginal birth with vertex presentation at delivery; the secondary outcome was compliance in the self-administration of the moxibustion treatment.

Results

We observed cephalic version and natural childbirth in 62.4% of all treated women. The treatment was accepted by 98.9% women (93/94), and compliance was 91.4% (85/93) for self-administered moxibustion and 37.5% (12/32) for moxibustion and needle treatment.

Conclusions

On the basis of our results, self-administered home treatment moxibustion followed by moxibustion and needle stimulations may be an effective and low-cost treatment for inducing cephalic version.

Caring for the Pregnant Woman and Her Baby in a Changing Maternity Service Environment: The Role of Acupuncture

Women have traditionally been high users of complementary therapies and use of these therapies continues during pregnancy and birthing. While women look to acupuncture and other therapies to support them during this time, traditional maternity services are in a state of change. In Australia, there is an increase in births, a workforce crisis, an increase in birthing in labour ward settings, few opportunities for women to birth at home, increased caesarean sections and an increase in obstetric interventions. The future role of acupuncture in this changed environment will be influenced by the evidence of safety and effectiveness of acupuncture. Research evaluating acupuncture during the antenatal period, labour preparation and birthing is small in quantity, but there are encouraging findings suggesting acupuncture maybe safe and effective. Women have prioritised interventions to manage pregnancy symptoms such as nausea and back pain, and interventions to prepare for labour and manage pain in labour as important. Further acupuncture trials are needed to ensure women have reliable and valid information to inform their decision making. Assessment of safety requires contributions from researchers, practitioners and integration with institutional data collection systems. Research of effectiveness should involve rigorous designs, but with debate about the appropriateness of traditional randomised controlled trial designs to evaluate complex interventions, and the limitations of sham controls, different approaches with mixed research methods should be considered. Exploring new research methods, especially those which explore the woman's experience with acupuncture, are also key to defining a role in the future.

Oriental herbal medicine and moxibustion for polycystic ovary syndrome: A meta-analysis

BACKGROUND

Polycystic ovary syndrome (PCOS) is one of the most common disorders of reproductive endocrinology in women of reproductive age. Lifestyle intervention and oral contraceptives are the first-line treatments for PCOS. Recent studies have suggested that complementary and alternative medicine (CAM) therapies including acupuncture, herbal medicine, and mind-body therapy have the potential to alleviate the symptoms and/or pathology of PCOS and to improve the quality of life of women with PCOS. This meta-analysis aimed to quantitatively summarize the efficacy and safety of moxibustion combined with oriental herbal medicine (OHM), common CAM therapies, for treating PCOS.

METHODS

Four databases were searched from their inception to June 22, 2018. Randomized controlled trials (RCTs) and quasi-RCTs using both OHM and moxibustion as experimental intervention, and western medication (WM) as control intervention were included. Studies involving OHM plus moxibustion combined with WM as the experimental intervention were also included. The quality of included studies was assessed using risk of bias tool.

RESULTS

Owing to the heterogeneity of reporting, meta-analysis was only performed for pregnancy rate, rate of normal biphasic basal body temperature (BBT), and total effective rate (TER). The results showed that compared to the WM group, the OHM combined with moxibustion group was associated with significantly higher pregnancy rate (risk ratio [RR] 1.95, 95% confidence interval [CI] 1.55-2.47; I = 0%), normal biphasic BBT rate (RR 1.66, 95% CI 1.34-2.05; I = 0%), and TER (RR 1.19, 95% CI 1.08-1.31; I = 0%). When OHM combined with moxibustion was used as an adjunctive therapy to WM, pregnancy rate (RR 1.65, 95% CI 1.29-2.11; I = 0%), and TER (RR 1.35, 95% CI 1.13-1.61; I = 43%) were significantly higher than those of the WM group.

CONCLUSION

According to current evidence, OHM combined with moxibustion might be beneficial for treating PCOS. Moreover, the treatment might improve the therapeutic effects of conventional WMs including clomiphene citrate, oral contraceptives, and/or metformin. However, the findings should be interpreted with caution, owing to poor methodological quality of the included studies. Further larger, high-quality, rigorous RCTs should be conducted in this regard.

Findings and Methodological Quality of Systematic Reviews Focusing on Acupuncture for Pregnancy-Related Acute Conditions

Introduction

Major concerns regarding the use of medication during pregnancy justify the need for safer interventions. Acupuncture is an emerging alternative for several clinical conditions during this period. The objective of this study is to summarise evidence derived from systematic reviews (SRs) focusing on acupuncture for pregnancy-related acute conditions.

Methods

Review of SRs. A systematic literature search was carried out in several electronic databases, aiming to include all SRs assessing the effects of acupuncture for acute conditions during pregnancy. Methodological quality and quality of the publication/reporting of each SR were assessed by the application of AMSTAR (Assessing the Methodological Quality of Systematic Reviews) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), respectively.

Results

The initial search retrieved 11 492 records, of which 16 SRs met our inclusion criteria. The average AMSTAR score was 7.3, the lowest score being 3 and the highest 11. The lowest PRISMA score was 12, the highest 25, and the average PRISMA score was 19.9. The results support the proposal that acupuncture might be considered an option for alleviating pain during labour, for correcting breech presentation, and for managing pelvic and back pain during pregnancy. There is insufficient evidence to recommend acupuncture for inducing labour, managing nausea and vomiting in early pregnancy, improving sleep quality, controlling nausea and vomiting associated with Caesarean delivery, and managing urinary infection.

Conclusions

Acupuncture might be an option for alleviating pain during labour, for correcting breech presentation, and for managing pelvic and back pain during pregnancy. More studies are needed to confirm the effects of acupuncture for other pregnancy-related acute conditions.

The Evaluation of Curative Effect of Acupuncture

The present study attempts to critically evaluate previously published research articles on the efficiency of acupuncture in the treatment of diseases. First, 35 systematic reviews or meta-analysis were found in the Cochrane database. Second, 54 related articles were selected by searching important scientific databases. Based on the results obtained regarding the efficacy of acupuncture for the treatment of various diseases, the articles were divided into 3 groups. The first group of articles confirmed the efficacy of treatment by acupuncture. In the second group of articles, the therapeutic effect of acupuncture was shown; however, further research is required to verify the results. In the third group of articles there is no evidence regarding the therapeutic effect of acupuncture till now. There is an urgent need to design and conduct double-blinded randomized clinical trials with high-quality methodologies. This provides a more careful evaluation of acupuncture efficiency in relation to the treatment of a vast array of diseases, based on scientific evidence.

The practice of acupuncture and moxibustion to promote cephalic version for women with a breech presentation: implications for clinical practice and research

OBJECTIVES

To examine what experienced acupuncture practitioners and researchers considered key aspects of treatment to promote cephalic version for women with a breech presentation, and to establish a treatment protocol through consensus to guide the self administration of moxa by pregnant women.

METHODS AND DESIGN

The Delphi method was used to seek the opinions of key informants. Sixteen English speaking international, Australian and New Zealand acupuncturists working in the area of pregnancy were invited to participate in the study. Participants were given a link to an online survey, and their views sought on treatment parameters guiding the treatment of breech presentation within a research setting.

RESULTS

Two rounds of the Delphi process were undertaken, 12 participants completed round one, and 10 completed round two. Eighty percent of participants agreed that moxa should commence between 34 and 35 weeks gestation. Ninety percent agreed to self administration of moxa by the woman, and use of smokeless and odourless sticks. Seventy percent agreed moxa should be applied for a minimum of 10 days, and be applied once a day for 30min. Monitoring safety was identified as an important outcome. Ninety percent agreed study clinical outcomes should assess side effects including burns, and maternal and foetal outcomes.

CONCLUSION

Findings from our study promote the clinical validity for a future research protocol, and highlight other areas for research to evaluate the role of acupuncture and moxibustion with normalising birth.

Research on Acupuncture in Pregnancy and Childbirth: The U.S. Contribution

BACKGROUND

Along with an increasing use of acupuncture to treat pregnancy and childbirth concerns comes a need to assess the current state of related research, which is a critical step in defining a research agenda.

OBJECTIVE

The goal of this article is to analyze the U.S. contribution to obstetric acupuncture research against the backdrop of professional positions and relevant historical events.

METHODS

Original obstetric acupuncture research articles published post-1998 (147) and pre-1998 (62) were reviewed. Studies were placed into topical categories (e.g., breech correction, labor, and delivery), and the current authors identified region of study origin, study focus and type, gestational timing of treatment, general study outcomes, and adverse events. U.S. study characteristics were analyzed relative to those of other regions.

RESULTS

The number of obstetric acupuncture publications more than tripled from pre- to post-1998, and the United States ranked third (behind the European region and China) in published articles. One case study indicated a serious adverse effect. Most post-1998 U.S. articles focused on pregnancy concerns; those conducted in early pregnancy involved acupressure. Acupuncture benefits varied by study topic.

CONCLUSIONS

U.S. studies reflected greater effort toward treating pregnancy-related problems, compared to childbirth and postpartum concerns. The U.S. research contribution is discussed within the context of health care system structure, professional concerns, funding, and the role of conventional biomedical care in advancing a successful research agenda.

Using moxibustion in primary healthcare to correct non-vertex presentation: a multicentre randomised controlled trial

OBJECTIVE

To compare the effectiveness of additional moxibustion at point BL67 with moxibustion at a non-specific acupuncture point and with usual care alone to correct non-vertex presentation.

METHODS

This was a multicentre randomised controlled trial in which 406 low-risk pregnant women with a fetus in ultrasound breech presentation, with a gestational age of 33-35 weeks, were assigned to (1) true moxibustion at point BL67 plus usual care; (2) moxibustion at SP1, a non-specific acupuncture point (sham moxibustion) plus usual care; or (3) usual care alone. The primary outcome was cephalic presentation at birth. Women were recruited at health centres in primary healthcare.

RESULTS

In the true moxibustion group, 58.1% of the full-term presentations were cephalic compared with 43.4% in the sham moxibustion group (RR 1.34, 95% CI 1.05 to 1.70) and 44.8% of those in the usual care group (RR 1.29, 95% CI 1.02 to 1.64). The reduction in RR of the primary outcome in women allocated to the true moxibustion group compared with the usual care group was 29.7% (95% CI 3.1% to 55.2%) and the number needed to treat was 8 (95% CI 4 to 72). There were no severe adverse effects during the treatment.

CONCLUSIONS

Moxibustion at acupuncture point BL67 is effective and safe to correct non-vertex presentation when used between 33 and 35 weeks of gestation. We believe that moxibustion represents a treatment option that should be considered to achieve version of the non-vertex fetus.

Heat stimulation on the skin for medical treatment: can it be controlled?

OBJECTIVES

It has become increasingly important for evidence-based medicine to have a proper control for randomized-controlled trials. However, appropriately controlling manual therapies such as moxibustion has proved challenging. Our team designed a novel device based on sensory illusion, and tested its feasibility.

DESIGN AND RESULTS

A sham moxibustion device was constructed to allow participants to feel moxibustion treatment without actually stimulating the corresponding acupoint. The device consisted of two pieces of aluminum, each shaped like a horseshoe, so that the center of the device would not touch the skin. Participants perceived two heat stimuli as one when the distances of two heat sources were within 15 mm on the forearm. The thermal stimulation of the sham device was adjusted to the lowest possible temperature, but enough to elicit a heat sensation (39°C), while that of verum was set at around 44°C. The subject blinding, tested in 30 healthy volunteers, was successful. With the exception of 1 subject, subjects in the sham group described the sensation as a warm solid circle, unable to differentiate between two-pieced sham moxibustion and verum moxibustion.

CONCLUSIONS

This preliminary study indicates that this device may serve as an appropriate control for clinical studies of moxibustion, but more research is clearly needed. A validated sham moxibustion device based on sensory illusion may contribute in expanding knowledge of somatosensory studies.

Acupuncture in obstetrics and gynecology: an overview of systematic reviews

Acupuncture is often recommended for obstetrical and gynecological conditions but the evidence is confusing. We aim to summarize all recent systematic reviews in this area. Western and Asian electronic databases were searched for systematic reviews of any type of acupuncture for any type of gynecological conditions. Our own files were hand-searched. Systematic reviews of any type of acupuncture for any type of gynecological conditions were included. Non-systematic reviews and systematic reviews published before 2004 were excluded. No language restrictions were applied. Data were extracted according to predefined criteria and analysed narratively. Twenty-four systematic reviews were included. They relate to a wide range of gynecological conditions: hot flashes, conception, dysmenorrhea, premenstrual syndrome, nausea/vomiting, breech presentation, back pain during pregnancy, and procedural pain. Nine systematic reviews arrived with clearly positive conclusions; however, there were many contradictions and caveats. The evidence for acupuncture as a treatment of obstetrical and gynecological conditions remains limited.

The effectiveness of moxibustion: an overview during 10 years

Moxibustion has been used to treat various types of disease. However, there is still insufficient evidence regarding its effectiveness. This study was performed to summarize and evaluate the effectiveness of moxibustion. A search was performed for all randomized controlled trials in PubMed between January 1998 and July 2008 with no language restriction. The results yielded 47 trials in which six moxibustion types were applied to 36 diseases ranging from breech presentation to digestive disorders. Moxibustion was compared to three types of control group: general care, Oriental medical therapies or waiting list. Moxibustion was superior to the control in 14 out of 54 control groups in 46 studies. There were no significant differences among groups in 7 studies, and the outcome direction was not determined in 33 studies. Seven studies were included in a meta-analysis. Moxibustion was more effective than medication in two ulcerative colitis studies (relative risk (95% CI), 2.20 (1.37, 3.52), P = .001, I² = 0%). Overall, our results did not support the effectiveness of moxibustion in specific diseases due to the limited number and low quality of the studies and inadequate use of controls. In order to provide appropriate evidence regarding the effectiveness of moxibustion, more rigorous clinical trials using appropriate controls are warranted.

Adverse events of moxibustion: a systematic review

OBJECTIVES

The aim of this review was to identify adverse events of moxibustion as reported in the medical literature.

METHODS

Computerised literature searches were carried out in 14 databases. All articles reporting adverse effects of any type from moxibustion in humans were included, regardless of study design and publication language. The related journals and references in all located articles were manually searched for further relevant articles. Data were extracted and evaluated according to predefined criteria by three independent reviewers.

RESULTS

Adverse events related to moxibustion treatment were reported in 4 randomised clinical trials, 1 controlled clinical trial, 2 uncontrolled observational studies, 13 case reports, and 1 prospective study. The most common effects identified in this review were allergic reactions, burns, and infections such as cellulitis and hepatitis C. Allergic reactions were reported in six case reports (four case reports related to infections and two related to burns). The other articles were case reports of xerophthalmia, xeroderma, hyperpigmented macules, ptosis and eversion of the eyelids. In clinical trials, various adverse events such as rubefaction, blistering, itching sensations, discomfort due to smoke, general fatigue, stomach upsets, flare-ups, headaches, and burns were reported. Tenderness and pressure in the epigastric region or in one of the hypochondriac regions, unpleasant odour with or without nausea and throat problems, abdominal pain, premature birth, premature rupture of the membrane and bleeding due to excess pressure on the anterior placenta were reported in pregnant women.

CONCLUSION

Moxibustion is not entirely risk free, as it has several kinds of potential adverse events such as allergy, burn and infection. Currently, the incidence of such events is not known. In the interest of patient safety, sufficiently large prospective studies should be considered to clarify this issue.

Cost-effectiveness of breech version by acupuncture-type interventions on BL 67, including moxibustion, for women with a breech foetus at 33 weeks gestation: a modelling approach

OBJECTIVES

To assess, using a modelling approach, the effectiveness and costs of breech version with acupuncture-type interventions on BL67 (BVA-T), including moxibustion, compared to expectant management for women with a foetal breech presentation at 33 weeks gestation.

DESIGN

A decision tree was developed to predict the number of caesarean sections prevented by BVA-T compared to expectant management to rectify breech presentation. The model accounted for external cephalic versions (ECV), treatment compliance, and costs for 10,000 simulated breech presentations at 33 weeks gestational age. Event rates were taken from Dutch population data and the international literature, and the relative effectiveness of BVA-T was based on a specific meta-analysis. Sensitivity analyses were conducted to evaluate the robustness of the results.

MAIN OUTCOME MEASURES

We calculated percentages of breech presentations at term, caesarean sections, and costs from the third-party payer perspective. Odds ratios (OR) and cost differences of BVA-T versus expectant management were calculated. (Probabilistic) sensitivity analysis and expected value of perfect information analysis were performed.

RESULTS

The simulated outcomes demonstrated 32% breech presentations after BVA-T versus 53% with expectant management (OR 0.61, 95% CI 0.43, 0.83). The percentage caesarean section was 37% after BVA-T versus 50% with expectant management (OR 0.73, 95% CI 0.59, 0.88). The mean cost-savings per woman was euro 451 (95% CI euro 109, euro 775; p=0.005) using moxibustion. Sensitivity analysis showed that if 16% or more of women offered moxibustion complied, it was more effective and less costly than expectant management. To prevent one caesarean section, 7 women had to use BVA-T. The expected value of perfect information from further research was euro0.32 per woman.

CONCLUSIONS

The results suggest that offering BVA-T to women with a breech foetus at 33 weeks gestation reduces the number of breech presentations at term, thus reducing the number of caesarean sections, and is cost-effective compared to expectant management, including external cephalic version.

Does acupuncture have a place as an adjunct treatment during pregnancy? A review of randomized controlled trials and systematic reviews

BACKGROUND

Complementary medicine has become popular throughout many Western countries and is widely used by women across all stages of their life cycle. Acupuncture is used by women during their pregnancy, and research suggests that acupuncture may be used as an adjunct to their existing conventional care. The aim of this paper was to summarize the evidence examining the effectiveness of acupuncture during pregnancy and birthing, and to discuss its role as an adjunct treatment.

METHODS

We conducted a systematic literature search using several electronic databases. We included all placebo-controlled randomized trials of parallel design, and systematic reviews that evaluated the role of acupuncture during pregnancy and birthing. A critical appraisal of clinical trials and systematic reviews was undertaken.

RESULTS

The summarized findings indicated a small but growing body of acupuncture research, with some evidence suggesting a benefit from acupuncture to treat nausea in pregnancy. Findings from the review also highlighted promising evidence for the effectiveness of acupuncture to manage back and pelvic pain, acupuncture-type interventions to induce change in breech presentation, and pain relief in labor. The methodological quality of recent trials has improved, and the quality of systematic reviews was high.

CONCLUSIONS

Interest is growing in the use of acupuncture to treat some complaints during pregnancy and childbirth, and evidence is beginning to consolidate that acupuncture may assist with the management of some complaints during pregnancy. However, definitive conclusions about its effectiveness cannot be reached and further research is justified.

Moxibustion and other acupuncture point stimulation methods to treat breech presentation: a systematic review of clinical trials

BACKGROUND

Moxibustion, acupuncture and other acupoint stimulations are commonly used for the correction of breech presentation. This systematic review aims to evaluate the efficacy and safety of moxibustion and other acupoint stimulations to treat breech presentation.

METHODS

We included randomized controlled trials (RCTs) and controlled clinical trials (CCTs) on moxibustion, acupuncture or any other acupoint stimulating methods for breech presentation in pregnant women. All searches in PubMed, the Cochrane Library (2008 Issue 2), China National Knowledge Information (CNKI), Chinese Scientific Journal Database (VIP) and WanFang Database ended in July 2008. Two authors extracted and analyzed the data independently.

RESULTS

Ten RCTs involving 2090 participants and seven CCTs involving 1409 participants were included in the present study. Meta-analysis showed significant differences between moxibustion and no treatment (RR 1.35, 95% CI 1.20 to 1.51; 3 RCTs). Comparison between moxibustion and knee-chest position did not show significant differences (RR 1.30, 95% CI 0.95 to 1.79; 3 RCTs). Moxibustion plus other therapeutic methods showed significant beneficial effects (RR 1.36, 95% CI 1.21 to 1.54; 2 RCTs). Laser stimulation was more effective than assuming the knee-chest position plus pelvis rotating. Moxibustion was more effective than no treatment (RR 1.29, 95% CI 1.17 to 1.42; 2 CCTs) but was not more effective than the knee-chest position treatment (RR 1.22, 95% CI 1.11 to 1.34; 2 CCTs). Laser stimulation at Zhiyin (BL67) was more effective than the knee-chest position treatment (RR 1.30, 95% CI 1.10 to 1.54; 2 CCTs,).

CONCLUSION

Moxibustion, acupuncture and laser acupoint stimulation tend to be effective in the correction of breech presentation.
