The trends and hotspots of research on non-pharmacological interventions for labor pain management: a bibliometric analysis

INTRODUCTION

This study aimed to examine important points of focus, trends, and depth of research on non-pharmacological interventions for the management of labor pain worldwide from a macro perspective and present an extensive definition of research fields regarding non-pharmacological interventions.

METHODS

Bibliometric methods were used in this study. With comprehensive keyword lists, the Web of Science and PubMed databases were searched using different screening strategies for publications made until 25 February 2023.

RESULTS

Studies on non-pharmacological interventions in the management of labor pain have continued to develop since 2003 with great momentum. In this study, the most productive country in research on non-pharmacological interventions was found to be Iran, while Australia, the USA, China, and the United Kingdom were the most notable ones in terms of collaboration. The most prevalently studied non-pharmacological interventions were hydrotherapy and acupuncture. The results of the co-word analysis revealed 5 main themes about this field of research.

CONCLUSION

The results of this study showed that interest in studies on non-pharmacological interventions in the management of labor pain has increased, the quality of research in the field is high, international collaboration is increasingly higher, and technological approaches have started to emerge in relevant studies.

The effect of antenatal hypnosis training on pharmacological analgesia use during labour and birth: A systematic review and meta-analysis

BACKGROUND

The use of hypnosis as a means of pain management during labour is becoming increasingly popular. While recent reviews have reported on pain perception, relaxation and other psychological benefits the impact of hypnosis on the use of pharmacological analgesia use has not been specifically examined.

QUESTION

For women in labour at term, does antenatal hypnosis instruction compared to no instruction result in decreased use of pharmacological analgesia and influence maternal and infant birth outcomes.

METHODS

Databases such as PubMed, CINAHL, Cochrane Central Register of Controlled Trials and Embase were searched with dates ranging from 1947-2024. We included randomised controlled trials (RCTs) that compared antenatal hypnosis training to no hypnosis control groups, published in English and reported on pharmacological analgesia use. The Cochrane's Risk of Bias 2 for RCTs was used to assess design quality. Study selection, quality assessment, data extraction and analysis were undertaken by two independent researchers.

FINDINGS

Six RCTs met the inclusion criteria (n=2937). The use of hypnosis did not result in a significant reduction in the risk of epidural use (RR. 0.79 95% CI 0.39-1.61) or other forms of pharmacological analgesia. Factors such as blinding of care providers to the participants allocated group may have reduced the chances of successful use of hypnosis. Variations in the presentation of hypnosis between studies may also impact on outcomes.

DISCUSSION AND CONCLUSION

This review reports no effect on the use of pharmacological analgesia in women trained in hypnosis antenatally compared with those who were not. Our review does highlight several RCT design characteristics that could impact on the measurement and analysis of the use and efficacy of hypnosis.

The effect of neurolinguistic programming on labor pain, fear, duration and maternal satisfaction: A randomized controlled trial

OBJECTIVES

Labor pain is one of the most severe pains experienced by women. In the literature, there is no research examining the effect of Neurolinguistic Programming (NLP) on birth pain and fear. It was aimed to determine the effect of NLP on labor pain, fear, duration, and maternal satisfaction in both nulliparous, and multiparous pregnant women.

DESIGN

This study consists of each with two arms, parallel-group randomized controlled trials, on two different samples for both nulliparous and multiparous women. Data were collected between 3 October 2023-21 January 2024. A total of 124 women (62 nulliparous and 62 multiparous women) who gave birth vaginally constituted the sample of the study. Both nulliparous and multiparous women were randomly assigned to groups. The primary outcomes were labor pain, fear, duration, and satisfaction. When the cervical span was 3-4, 5-6, and 7-8 cm, NLP was applied to the experimental group for 20 min each, the control group rested for 20 min each.

RESULTS

According to the measurement times, the mean pain score of the experimental group was lower than the control group. The mean VAS pain score measured over time decreased by 90.3 % in the NLP group compared to the control group for primiparous and 64.5 % compared to the control group for multiparous. In both nulliparous and multiparous, the fear of labor of the NLP group was lower, the duration of labor was shorter, and the satisfaction with labor was higher compared to the control group (p < 0.05).

CONCLUSION

NLP reduces labor pain and fear, shortens the duration of labor, and increases maternal satisfaction in labor.

The effect of non-pharmacological prenatal interventions on fear of childbirth: an overview of systematic reviews and meta-analysis

BACKGROUND

During pregnancy and childbirth, alongside positive feelings, women undergo feelings such as fear of childbirth (FoC) and worry about its consequences, which could leave negative effects on the mother and her child during pregnancy, delivery, and postpartum. The study was carried out to determine the effectiveness of prenatal non-pharmacological interventions on reducing the FoC.

METHODS

The protocol of the study was registered in PROSPERO (ID: CRD42023468547). PubMed, Web of Science, Cochrane, Scopus, SID (Scientific Information Database) and Google Scholar search engine databases were systematically searched until July 27, 2023 with no limitation of time and limited to Persian and English studies in order to perform this overview. Certainty of evidence was assessed using GRADE, methodological quality using AMSTAR 2 and reporting quality using PRISMA score. Meta-analysis was performed on the data extracted from the original trials to evaluate the effect of different interventions on reducing the FoC. Sub-group analysis and meta-regression models were used to examine high heterogeneity, and sensitivity analysis was used to eliminate the effect of high risk of bias studies on the study findings.

RESULTS

Overall, 15 systematic reviews (SRs) were included in the overview, among which meta-analysis was performed in 9 studies. Considering methodological quality, these SRs were in low to critically low status and had relatively complete reports regarding reporting quality. Meta-analysis findings indicated that psychological interventions (SMD -2.02, 95% CI -2.69 to -1.36, 16 trials, 1057 participants, I2 = 95%) and prenatal educations (SMD -0.88, 95% CI -1.16 to -0.61, 4 trials, 432 participants, I2 = 72.8%) cause a significant reduction in FoC relative to prenatal usual cares with low certainty of evidence. Distraction techniques lead to a significant reduction in FoC relative to prenatal usual care with high certainty of evidence (SMD -0.75, 95% CI -1.18 to -0.33, 4 trials, 329 participants, I2 = 69%), but enhanced cares do not result in a significant decrease FoC relative to prenatal usual care with very low certainty of evidence (SMD -1.14, 95% CI -2.85 to 0.58, 3 trials, 232 participants, I2 = 97%).

CONCLUSIONS

Distraction techniques are effective in reducing FoC. Regarding the effect of psychological interventions and prenatal educations on the reduction of FoC, the findings indicated that the interventions may result in the reduction of FoC. Very uncertain evidence showed that enhanced cares are not effective in reducing the FoC.

Midwives' experience of telehealth and remote care: a systematic mixed methods review

INTRODUCTION

Increasing the midwifery workforce has been identified as an evidence-based approach to decrease maternal mortality and reproductive health disparities worldwide. Concurrently, the profession of midwifery, as with all healthcare professions, has undergone a significant shift in practice with acceleration of telehealth use to expand access. We conducted a systematic literature review to identify and synthesize the existing evidence regarding how midwives experience, perceive and accept providing sexual and reproductive healthcare services at a distance with telehealth.

METHODS

Five databases were searched, PubMed, CINHAL, PsychInfo, Embase and the Web of Science, using search terms related to 'midwives', 'telehealth' and 'experience'. Peer-reviewed studies with quantitative, qualitative or mixed methods designs published in English were retrieved and screened. Studies meeting the inclusion criteria were subjected to full-text data extraction and appraisal of quality. Using a convergent approach, the findings were synthesized into major themes and subthemes.

RESULTS

After applying the inclusion/exclusion criteria, 10 articles on midwives' experience of telehealth were reviewed. The major themes that emerged were summarized as integrating telehealth into clinical practice; balancing increased connectivity; challenges with building relationships via telehealth; centring some patients while distancing others; and experiences of telehealth by age and professional experience.

CONCLUSIONS

Most current studies suggest that midwives' experience of telehealth is deeply intertwined with midwives' experience of the response to COVID-19 pandemic in general. More research is needed to understand how sustained use of telehealth or newer hybrid models of telehealth and in-person care are perceived by midwives.

Hypnosis in the operating room: are anesthesiology teams interested and well-informed?

BACKGROUND

Hypnosis can be a beneficial complementary anesthesia technique for a variety of surgical procedures. Despite favorable scientific evidence, hypnosis is still rarely used in the operating room. Obstacles to implementation could be a lack of interest or training, misconceptions, as well as limited knowledge amongst anesthesiology teams. Hence, this study aimed to assess the interest, training, beliefs, and knowledge about hypnosis in the operating room staff.

DESIGN

A questionnaire with 21-items, based on a prior survey, was set up on an online platform. The medical and nursing anesthesiology staff of four Swiss academic and large regional hospitals (N = 754) were invited to participate anonymously through e-mails sent by their hierarchy. Results were analyzed quantitatively.

RESULTS

Between June, 2020 and August, 2021 353 answers were collected (47% response rate). Most (92%) were aware that hypnosis needs specific training, with 14% trained. A large majority of the untrained staff wished to enroll for conversational hypnosis training. There was a strong agreement for hypnosis playing a role in anesthesia. Nevertheless, many of these professionals believed that hypnosis has a limited field of action (53%) or that it would be too time consuming (33%). The reduction of misconceptions was based more on exposure to hypnosis than on training.

CONCLUSION

Overall, anesthesia providers' attitude was in favor of using hypnosis in the operating room. Misconceptions such as a prolongation of the procedure, alteration of consent, lack of acceptability for patients, and limited indications were identified as potential barriers. These deserve to be challenged through proper dissemination of the recent scientific literature and exposure to practice.

Psychological impact of hypnosis for pregnancy and childbirth: A systematic review

BACKGROUND

The use of hypnosis as a complementary therapy in the perinatal field is expanding, however, there is little research for its impact on perinatal mental health. Here, we review studies that evaluate the effect of hypnosis on women's mental health and subjective experiences.

METHODS

A systematic review was conducted according to the PRISMA protocol for articles with experimental designs of hypnosis that measured their impact on several psychological variables, such as the presence of symptoms of anxiety, depression or fear of childbirth. Studies were evaluated according to the Critical Appraisal Skills Program Checklists (CASP), and analyzed for their designs and intervention themes.

RESULTS

Seven studies were included and six themes emerged: preparation for birth and unexpected events; change in the perception and experience of pain; pregnant body as a natural process; connection with the baby during pregnancy; development of inner resources; and progressive relaxation and guided imagery. Although results were partly mitigated, most studies found positive effects of hypnosis in alleviating anxiety, depression, and fear towards birth, empowering women with a higher sense of confidence and improving the overall emotional experience. Two studies also indicate encouraging outcomes in postnatal wellbeing.

CONCLUSION

While it is still argued as to what extent hypnosis has positive effects on physical aspects of labor, the empowerment and the increase in confidence associated with hypnosis seem to bring a significant contribution to a more positive subjective experience of pregnancy and childbirth, and on women's overall wellbeing in the perinatal period.

A Systematic Review of the Effects of Second-Eye Cataract Surgery on Motor Function

Cataract removal surgery is one of the most commonly performed surgical procedure in developed countries. The financial and staff resource cost that first-eye cataract surgery incurs, leads to restricted access to second-eye cataract surgery (SES) in some areas, including the United Kingdom. These restrictions have been imposed despite a lack of knowledge about the impact of not performing SES on visuo-motor function. To this end, a systematic literature review was carried out, with the aim of synthesising our present understanding of the effects of SES on motor function. Key terms were searched across four databases, PsycINFO, Medline, Web of Science, and CINAHL. Of the screened studies (K = 499) 13 met the eligibility criteria. The homogeneity between participants, study-design and outcome measures across these studies was not sufficient for meta-analyses and a narrative synthesis was carried out. The evidence from objective sources indicates a positive effect of SES on both mobility and fall rates, however, when considering self-report measures, the reduction in falls associated with SES becomes negligible. The evidence for any positive effect of SES on driving is also mixed, whereby SES was associated with improvements in simulated driving performance but was not associated with changes in driving behaviours measured through in vehicle monitoring. Self-report measures of driving performance also returned inconsistent results. Whilst SES appears to be associated with a general trend towards improved motor function, more evidence is needed to reach any firm conclusions and to best advise policy regarding access to SES in an ageing population.

Guidelines for the Assessment of Efficacy of Clinical Hypnosis Applications

Research on the efficacy of hypnosis applications continues to grow, but there remain major gaps between the science and clinical practice. One challenge has been a lack of consensus on which applications of hypnosis are efficacious based on research evidence. In 2018, 6 major hypnosis organizations collaborated to form the Task Force for Establishing Efficacy Standards for Clinical Hypnosis. This paper describes a Guideline for the Assessment of Efficacy of Clinical Hypnosis Applications developed by the Task Force, which makes 10 specific recommendations. The guideline is intended to be a tool for those who want to assess the quality of existing evidence on the efficacy of clinical hypnosis for any particular indication. The paper also discusses methodological issues in the interpretation and implementation of these guidelines. Future papers will report on the other products of the Hypnosis Efficacy Task Force, such as best practice recommendations for outcomes research in hypnosis and an international survey of researchers and clinicians on current practice and attitudes about hypnosis.

Women's experiences throughout the birthing process in health facilities in Arab countries: a systematic review

BACKGROUND

Mistreatment of women during facility-based childbirth has become a significant public health issue globally and is gaining worldwide attention. This systematic review of quantitative studies aimed to estimate the prevalence of mistreatment women may experience throughout the birthing process in health facilities in Arab countries. The review also aimed to identify the types of mistreatment, terminology, tools, and methods used to address this topic.

METHODOLOGY

The search was conducted using three electronic databases: "PubMed," "Embase," and "CINAHL" in May 2020. Studies meeting the inclusion criteria were included and assessed for risk of bias. The analysis was conducted based on the evidence-based typology developed by Bohren et al. as a guide to try to estimate the prevalence of mistreatment.

RESULTS

Eleven studies out of 174 were included. The included studies belonged to only seven Arab countries out of 22 Arab countries. The mistreatment of women during childbirth is still new in the region. Searching within the included studies yielded diverse and indirect terms that were a proxy for the word mistreatment. These terms were not comprehensive to cover different aspects of the topic. The tools that were used to measure the terms widely varied.. Moreover, it was not possible to estimate the prevalence of mistreatment of women due to high heterogeneity among the 11 studies.

CONCLUSION

The topic of mistreatment of women in Arab countries was not adequately addressed in the studies included in this review. More research on this topic is recommended due to its importance in improving maternal health in the region. However, a standardized and comprehensive terminology for mistreatment of women, a standardized tool, and a standardized methodology are recommended to enable comparability between results and allow pooling to estimate the prevalence.

A pilot survey of clinicians' experiences, attitudes, and interests in hypnosis

Growing evidence supports the use of clinical hypnosis for medical and mental health applications. Most health care professionals lack training in hypnosis, and this may impact their readiness to recommend it. This study examined experiences, attitudes, and interests in hypnosis among health care professionals from a variety of disciplines. Thirty-seven health care professionals completed an online survey prior to attending a talk on hypnosis. Half of survey respondents were physicians or nurses. Most reported no training in hypnosis (70.3%), but half had previously experienced hypnosis. Participants displayed an understanding of common myths and misconceptions regarding hypnosis and felt hypnosis could be useful in health care settings. Despite this, the majority indicated they are rarely or never asked about hypnosis by their patients. A significant majority of survey participants believed individuals providing hypnosis should have both training and certification.

Integrative and complementary practices to control nausea and vomiting in pregnant women: a systematic review

OBJECTIVE

to synthesize the evidence available in the literature on the effects of integrative and complementary practices in nausea and vomiting treatment in pregnant women.

METHOD

a systematic review, reported according to PRISMA and registered in PROSPERO. The search for studies was carried out in 11 databases. To assess risk of bias in randomized clinical trials, the Cochrane Collaboration Risk of Bias Tool (RoB 2) was used.

RESULTS

the final sample consisted of 31 articles, divided into three categories: aromatherapy, phytotherapy and acupuncture. It was observed that aromatherapy with lemon essential oil, ginger capsules, pericardial 6 point acupressure were the interventions that proved to be effective. Less than half of studies reported adverse effects, with mild and transient symptoms predominating. Most articles were classified as "some concern" in risk of bias assessment.

CONCLUSION

the three most effective interventions to control gestational nausea and vomiting were aromatherapy, herbal medicine and acupuncture, with significant results in the assessment of individual studies.
