“Acupuncture Treatment During Labor”: The Effects of Acupuncture on the Labor Process

Introduction

Acupuncture treatment during labor —a randomized controlled trial is an article that appears in BJOG- an International Journal of Obstetrics and Psychology and was authored by Agneta Ramnero, Ulf Hanson, and Mona Kihlgren. All three are professionals in the field of obstetrics and gynecology: Ramnero is a researcher in the Department of Obstetrics and Gynaecology, Orebro University Hospital, Orebro, Sweden, Hanson works at the Centre for Nursing Science at the same university while Kihlgren works in the Department of Obstetrics and Gynecology, Uppsala University Hospital, Uppsala, Sweden. This paper has been cited by several researchers and this attests to its credibility.

Acupuncture treatment during labor investigates the use of acupuncture to reduce pain and bring relaxation during labor, and to improve the labor experience (Ramnero et al, 2002). The authors mention that acupuncture has been used by the Chinese for thousands of years and has recently been used widely in Sweden during childbirth. However, the effectiveness of this treatment method has not been ascertained through any randomized controlled trial experiment, and hence a justification for undertaking the research. In addition, various studies done previously have had varying findings in the use of acupuncture during pregnancy, labor, and childbirth. Tempfer et al (1998) reported that acupuncture treatment significantly reduced the duration of labor and could be proposed as a valuable tool in prenatal preparation, Skilnand et al (2002) reported that acupuncture reduces labor pains and shortens delivery time, while Lyrenäsa et al (1987) reported that acupuncture treatment did not shorten delivery time, rather, this treatment method lengthened pregnancy and increased and prolonged labor. Therefore, the research aims at clearing out the confusion as to the use of acupuncture during labor.

Objective

In undertaking the research, the researchers seek to document the effectiveness of using acupuncture during labor concerning reducing pain, level of relaxation, and the result of the delivery in comparison with the conventional analgesic method.

Methods

The research employs a randomized controlled trial design. This design is useful for testing the safety or efficacy of healthcare processes, hence, it is applicable for this research. The authors propose to test the hypothesis by determining whether acupuncture treatment during labor brought some degree of relaxation and improved the delivery outcome.

The study was undertaken during a 14-month duration at a health center in Sweden, the chosen health center has a mean of 2200 deliveries annually. The research used 100 women, a number that is low as it represents only 4.5% of all births in the hospital annually, and the research lasted 14 months. A larger sample, say of 660 (30%) would give a better outcome. Indeed, a previous study undertaken by Borup et al (2009) on the effectiveness of acupuncture during delivery used a sample size of 607 women. In the present study, 51 women were given acupuncture treatment while 49 did not receive the treatment (control sample). 5 women from each sample were marked as missing since they did not meet the qualifications required of the samples. All data collected during the experiment were recorded by midwives during each delivery. The information included the use of analgesia, age of the participants, duration of labor, the outcome of birth, and child birth weights.

The data collected was adequate to answer the research question as the study generally investigated the effects of acupuncture during labor.

Data Analysis and Results

The experimental data were analyzed using SPSS with a 95% confidence interval for both discrete and continuous data while differences between group means were measured using a Student’s t-Test and variations in frequencies calculated using the chi-squared test. Assessments of the levels of pain were made by the individual members of the sample (parturient) as they can give more accurate results than an observer. This was done to eliminate discrepancies in pain assessment between observer and parturient in previous studies (Rajan, 1993).

The researchers report that there were no noteworthy variations in the labor process, i.e. frequency of vaginal births and length of labor. However, there was a considerable feeling of relaxation arising from the use of acupuncture.

Discussion of Findings

The author’s conclusion that acupuncture did not affect the outcome of the labor process ignored some important aspects. Duration of labor is affected by several factors, especially in the first stage. One factor is obstetric analgesia. Although Ramnero et al seem less bothered by the fact that women who received acupuncture treatment did not have a lower need for analgesics, these women may have received it afterward if there was a belief that less analgesia would be essential. The authors do not provide this information. The authors also fail to give vital information that would have affected the outcome of the study, these include the mean age of the sample size, parity (number of children delivered previously), and blood pressure.

Factors such as psychotherapy, stress reduction sessions, psychological support at home and work, or any plausible intervention technique play the same role as acupuncture.

Other factors that affect the duration of labor are not mentioned in the report, for example, the presence of a supportive companion is known to shorten the labor duration by up to 10 hours (Langer et al, 1998), and a consideration of this factor would have the study more accurate. A report of this nature should not have ignored the effects of psychosocial support, besides, it is unacceptable that the control sample group was not accorded any form of placebo intervention. Even if the findings of this report were positive on the use of acupuncture during the labor process, the findings in this setting would have been forced through non-clinical methods. There are more scientific, pleasant, and rational methods of eliciting responses during the research of this kind.

Conclusion

In choosing to undertake a study on the effects of acupuncture on the labor process, Ramnero et al sought to clear out the uncertainty as to whether acupuncture treatment affects this process concerning the duration of birth, relaxation, and reduction of pain. Even though their findings and conclusion agree with those from previous studies, some fundamental aspects of experimental research were not attained, and these are likely to have affected the outcome. Therefore, more research needs to be done on this topic. Future studies need to consider all variables that can affect the parturition process, these include the mean age of the sample size, parity, blood pressure, the presence of a supportive companion, and psychological support before the parturition process. Besides, a larger sample size spread over a wider geographical area will give better results.

The authors identify the study limitations and propose that future trials should use a larger sample.
