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

Complementary and alternative medicine use by pregnant women in Japan: a pilot survey

BACKGROUND

Complementary and alternative medicine (CAM) are popular among women, and are used during their pregnancy in Japan. This study aimed to survey the prevalence of CAM use by healthy pregnant women as a health-care prescribed therapy or self-care and to investigate the factors associated with CAM use in Japan.

METHODS

In this cross-sectional study, pregnant women after 34 weeks of gestation were asked to respond to a questionnaire at the clinic or online. The questionnaire comprised questions on the participants' characteristics and their use of CAM for therapy and self-care. Descriptive statistics were calculated in the analyses, and bivariate and multivariate logistic analyses were performed to evaluate the associations between factors and CAM use.

RESULTS

A total of 394 women responded from three hospitals, two clinics, and two midwifery birth centers. CAM was received as treatment by practitioners during pregnancy by 75 women (19.0%). The following therapies were used: traditional Chinese medicine (7.9%), chiropractic (6.9%), moxibustion (6.4%), and acupuncture (5.3%). One or more types of therapy were used as self-care by 348 women (88.3%). Highly used CAM for self-care were: folic acid supplementation (75.4%), other supplements (51.5%), herbs (20.8%), and yoga (19.0%). Multiple logistic regression analyses revealed that the factors associated with CAM use as a therapy were midwifery birth centers for planned childbirth settings (adjusted odds ratio [AOR] 3.64, 95% confidence interval [CI] [1.69-7.83]) and pregnancy complications diagnosed (AOR 2.46, 95%CI [1.38-4.39]). The factors associated with CAM use for self-care were age 30-39 years (AOR 4.48, 95%CI [2.14-9.73]) and over 40 years (AOR 3.92, 95%CI [1.10-13.91]), junior college education or above (AOR 2.30, 95%CI [1.18-4.51]), and primiparas (AOR 3.82, 95%CI [1.86-7.86]). The most common source of information was the "Internet" (43.8%).

CONCLUSIONS

Approximately 20% of Japanese pregnant women received CAM as therapy by practitioners, and the related factors were: tended to have baby at midwifery birth center and pregnancy complications. Almost 90% of respondents used CAM as self-care and the related factors were: older, had a higher educational level and tended to be primiparas. They used the Internet as their main source of information about CAM. Health care providers need to provide evidenced-based information on CAM and to help decision making to ensure safe and effective CAM utilization by pregnant women.

Evaluating the effectiveness of lateral postural management for breech presentation: study protocol for a randomized controlled trial (BRLT study)

BACKGROUND

Breech presentation is observed in 3-4% at term of pregnancy and is one of the leading causes of cesarean section. There is no established treatment for breech presentation before 36 weeks. A retrospective cohort study was conducted to demonstrate that the lateral position is effective for breech presentation. However, there are no randomized controlled trials evaluating lateral position management for breech presentation. Here, we described the methodology of a randomized controlled trial of a cephalic version for breech presentation in the third trimester by lateral postural management (BRLT study).

METHODS

The BRLT study is an open-label, randomized controlled trial with two parallel groups allocated in a 1:1 ratio to examine the lateral position management for breech presentation, as compared with expectant management care. An academic hospital in Japan will enroll 200 patients diagnosed with a breech presentation by ultrasonography between 28 + 0 weeks and 30 + 0 weeks. Participants in the intervention group will be instructed to lie on their right sides for 15 min three times per day if the fetal back was on the left side or lie on their left sides if the fetal back was on the right side. The instruction will be given every 2 weeks after confirmation of fetal position, and the lateral position will be instructed until the cephalic version, and after the cephalic version, the reverse lateral position will be instructed until delivery. The primary outcome is cephalic presentation at term. The secondary outcomes are cesarean delivery, cephalic presentation 2, 4, and 6 weeks after the instruction, and at delivery, recurrent breech presentation after cephalic version, and adverse effects.

DISCUSSION

This trial will answer whether the lateral positioning technique is effective in treating breech presentation and, depending on the results, may provide a very simple, less painful, and safe option for treating breech presentation before 36 weeks, and it may impact breech presentation treatment.

Cephalic version by postural management in the lateral position without the knee-chest position for primiparous breech presentation: A retrospective cohort study

AIM

This study aimed to determine the efficacy of postural management in the lateral position for primiparous breech presentation.

METHODS

A retrospective cohort study was conducted at a single institution from January 2020 through December 2020. Participants were singleton primiparous pregnant women diagnosed with breech presentation between 28 + 0 and 29 + 6 weeks of gestation. The exclusion criteria were scheduled cesarean delivery, uterine malformation, transverse position, and scheduled delivery at another hospital. A doctor instructed the women in the intervention group to lie on their right sides several times a day if the fetal back was on the left side or lie on their left sides if the fetal back was on the right side. The knee-chest position and other methods were not recommended. The control group received expectant management care. The primary endpoint was the percentage of fetuses in a cephalic presentation 2 weeks later.

RESULTS

Of the 56 women included in the study, 17 women were instructed to lie in the lateral position, and 39 women received expectant management care only. After 2 weeks, women who were instructed to lie in lateral position had a higher rate of fetal cephalic version than the control group (82.4% [14/17] vs. 43.6% [17/39], p = 0.017). No study participants experienced adverse effects.

CONCLUSIONS

Two weeks of postural management in the lateral position without the knee-chest position significantly reduced the rate of primiparous breech presentation in the third trimester of pregnancy.

Effectiveness of Moxibustion for Breech Presentation: A Prospective Study

OBJECTIVE

To evaluate the moxibustion for turning fetuses from breech to vertex presentation.

MATERIALS AND METHODS

This was a single-center prospective study. All pregnant women carrying a fetus in breech presentation between the 32 and 35 gestational weeks were offered moxibustion application. The primary outcomes were vertex presentation at 37 weeks of gestation, vertex presentation at birth, and vaginal birth rates. A secondary analysis was performed to understand the effect of parity, type of breech presentation, body mass index (BMI), placental location, gender, and fetal birth weight on the presentation at birth.

RESULTS

There were 63 cases in the study group and 245 cases in the control group. The rate of vertex presentation at term was found to be higher in the moxibustion group compared to controls (66.7 vs. 48.2%, p=0.022). There were 45 (71.4%) and 131 (53.5%) fetuses with vertex presentation at birth in the study and control groups, respectively (p=0.020). Overall, vaginal delivery rate was higher in the study group (50.8 vs. 37.1%, p=0.048). Multiparity and higher birth weight were associated with increased rates of vertex presentation in the moxibustion and control groups.

CONCLUSION

Moxibustion application increased the rate of vertex presentation at birth and also vaginal delivery rate compared with expectant management. Offering moxibustion between the 32nd and 36th week of gestation may provide women with a singleton fetus in breech presentation an opportunity for a vaginal birth.

The Application of Hypnosis in Obstetrics

Hypnosis, the induction of a naturally relaxed state of mind and body, is most commonly practiced by pregnant women in preparation for the childbirth experience. A literature review was performed to assess the effects of hypnosis before, during and after pregnancy. The majority of data is extracted from case series and low-quality studies thereby limiting the acceptability of hypnosis for various pregnancy related conditions. A few well-designed studies show that self-hypnosis may be beneficial for mitigating labor pain and fear of childbirth. Women can safely pursue hypnotherapy during pregnancy; however, high quality trials are needed to demonstrate its complete efficacy.

Complementary and Alternative Medicine for Threatened Miscarriage: Advantages and Risks

Threatened miscarriage is one of the most common complications causing pregnancy loss, and it affects approximately 20% of confirmed pregnancies. More and more women are seeking treatment with complementary and alternative medicine (CAM) for this common complication, and it has been reported that women have had successful pregnancies after threatened miscarriage when being treated with CAM, which mainly includes Chinese herbal medicines, acupuncture, and nutritional supplements as well as psychological interventions and other approaches. However, many experts are concerned about the safety and adverse events of certain CAM approaches in women with threatened miscarriage. Therefore, this review focuses on the status of CAM for threatened miscarriage and presents the potential therapeutic efficacy and safety of CAM based on some clinical and experimental studies. We thus hope to provide some instructive suggestions for the application of CAM for treating threatened miscarriage in the future.
