Music intervention for pain and anxiety management of the primiparous women during labour: A systematic review and meta‐analysis

The role and outcomes of music therapy during pregnancy: a systematic review of randomized controlled trials

INTRODUCTION

The abundant functions of music and its effects on human's mental and physical health have been verified since ancient times, but rarely received attention as an alternative obstetric intervention.

OBJECTIVE

This study aims to investigate the benefits of music therapy on prenatal and delivery experiences of pregnant women.

METHOD

A systematic search for articles was conducted in electronic databases including CINAHL, Web of Science, PubMed/Medline, and CNKI. A total of 240 articles were identified, and 17 studies were selected for this review. The extracted data included author, year, location, sample size, intervention phase, type of music, music therapy strategy, measuring instruments, and results. The data were organized chronologically based on the publication year of each study.

RESULT

The articles indicated that music therapy has advantages in reducing pain during childbirth, lowering anxiety and stress levels in mothers, improving sleep quality, and increasing fetal movements, basal fetal heart rate, and accelerations.

CONCLUSION

Based on the findings, it can be concluded that music therapy is an effective approach to enhance the experience of pregnant women during pregnancy and delivery. Therefore, its implementation in obstetrical clinical practice is highly recommended.

Designing and developing a nature-based virtual reality with heart rate variability biofeedback for surgical anxiety and pain management: evidence from total knee arthroplasty patients

OBJECTIVES

Total knee arthroplasty (TKA) is one of the most common joint surgeries, with over a million procedures performed annually in the US. Over 70% of patients report moderate to high pain and anxiety surrounding TKA surgery, and 96% are discharged with an opioid prescription. This population requires special attention as approximately 90% of TKA patients are older adults and one of the riskiest groups prone to misusing opioids. This study aimed to develop and compare the efficacy of nature-based virtual reality (VR) with heart rate variability biofeedback (HRVBF) to mitigate surgical pain and anxiety.

METHODS

This randomized control trial recruited 30 patients (mean age = 66.3 ± 8.2 years, 23 F, 7 M) undergoing TKA surgery and randomly assigned to a control, 2D video with HRVBF, or VR with HRVBF group. A visual analog scale (VAS) was used to measure pain levels before and after the intervention. In addition, a second VAS and the State-Trait Anxiety Inventory (STAI) were used to measure anxiety before and after the intervention. Electrocardiogram (ECG) was used to continuously measure HRV and respiration rate in preoperative and postoperative settings.

RESULTS

VR and 2D-video with HRVBF decreased pain and anxiety post-intervention compared with the control group, p's <.01. On analyzing physiological signals, both treatment groups showed greater parasympathetic activity levels, and VR with HRVBF reduced pain more than the 2D video, p < .01.

CONCLUSIONS

Nature-based VR and 2D video with HRVBF can mitigate surgical pain and anxiety. However, VR may be more efficacious than 2D video in reducing pain.

Current scenario and potential of music therapy in the management of diseases

Over the preceding years, music therapy has gained tremendous attention due to new findings of music in management of various conditions like Alzheimer's, depression, anxiety, insomnia, etc. Music is a non-invasive, patient-friendly and pleasant form of therapy with minimal or no side effects. It activates the reward pathway of brain by influencing several processes such as dopamine release, reduction in cortisol levels, increase in estrogen and testosterone levels. This review article focuses on advantages and disadvantages of music therapy, mechanism of action of music in brain and its effective applications in the management of different diseases. The article covers history of music therapy in America, Egypt, and India with practice of music therapy. The advanced effects of music therapy in autism, cancer, post-operative pain, Parkinson's disease, selective mutism, stroke, heart problems, pregnancy, eating disorders, bone fractures and obsessive compulsive disorders are discussed. Also the effect of music therapy on the quality of sleep and brain waves has been discussed. This is an established profession in western countries like America, UK, Australia, and Canada, but not in low-income countries like India where it needs to be standardized.

The Effects of Music-Based Interventions for Pain and Anxiety Management during Vaginal Labour and Caesarean Delivery: A Systematic Review and Narrative Synthesis of Randomised Controlled Trials

Music-based interventions are not physically invasive, they usually have minimal side effects, and they are increasingly being implemented during the birthing process for pain and anxiety relief. The aim of this systematic review is to summarise and evaluate published, randomised controlled trials (RCTs) assessing the effects of music-based interventions for pain and anxiety management during vaginal labour and caesarean delivery. Following the PRISMA guidelines, a systematic search of the literature was conducted using: PsychInfo (Ovid), PubMed, and Web of Science. Studies were included in the review if they were RCTs that assessed the effects of music on pain and anxiety during vaginal and caesarean delivery by human mothers. A narrative synthesis was conducted on 28 identified studies with a total of 2835 participants. Most, but not all, of the included studies assessing music-based interventions resulted in reduced anxiety and pain during vaginal and caesarean delivery. Music as part of a comprehensive treatment strategy, participant-selected music, music coupled with another therapy, and relaxing/instrumental music was specifically useful for reducing light to moderate pain and anxiety. Music-based interventions show promising effects in mitigating pain and anxiety in women during labour. However, the long-term effects of these interventions are unclear.

A music-with-movement exercise programme for community-dwelling older adults suffering from chronic pain: A pilot randomized controlled trial

AIM

This study developed, implemented and tested the effectiveness of a music-with-movement exercise programme in improving the pain situations of older adults with chronic pain.

DESIGN

A pilot randomized controlled trial.

METHODS

This was a pilot randomized controlled trial. The intervention was an 8-week music-with-movement exercise (MMEP) programme for older adults with chronic pain recruited in elders' community centres. The control group received the usual care and a pain management pamphlet. Outcome variables were pain intensity, pain self-efficacy and pain interference, depression and loneliness.

RESULTS

Seventy-one participants joined this study. Pain intensity was significantly reduced between the experimental group compared to the control group. The experimental group participants reported significant improvements in pain self-efficiency, pain interference and reduced loneliness and depressive symptoms. However, no significant difference was observed between groups.

The effect of music-based interventions on short-term postpartum episiotomy pain: A systematic review and meta-analysis

Episiotomy took over as the most common surgery in the field of midwifery that was performed in the second stage of labor to facilitate delivery, and reduce perineal damage. Music is one of the methods used to combat pain. We applied a meta-analysis to investigate whether music-based interventions can reduce short-term postpartum episiotomy pain. Four main English databases including Embase, PubMed, Web of Science, and Scopus were searched until July 2022. All randomized controlled trials (RCTs) with at least two groups (control and intervention) that aimed to measure the effect of music therapy on episiotomy pain were included in the present review. The Cochrane risk of bias checklist was used to assess study quality. Study heterogeneity was determined using the I² statistic and publication bias using Begg's and Egger's tests. Results of random effect analysis are presented as Standard Mean Difference (SMD) with 95% confidence intervals (CI). Data were analyzed using the STATA software version 16. In total, seven articles with 677 subjects were included in the meta-analysis. Overall, the pool estimates of the meta-analysis demonstrated that music therapy has a positive impact on reducing short-term pain derived from episiotomy in both primiparous and multiparous compared to the control group (pooled SMD = -1.60; CI = -2.18, -1.02, p-value<0.001). The heterogeneity was high among including studies (I² = 95.7%, p < 0.001). Our result showed that music-based interventions can be considered a choice for the management of short-term postpartum episiotomy pain among both primiparous and multiparous women. Future studies with large sample sizes and longer follow-up periods will be required to draw better conclusions about the long-term effects on postpartum pain.

Women's sense of control during labour and birth with epidural analgesia: A qualitative descriptive study

BACKGROUND

Sense of control during childbirth is a critical issue concerning the association between high-quality maternity care and infant health. This study explored the facilitators of or barriers to a sense of control and the need for interventions to raise women's experience in childbirth.

METHODS

The data came from 17 participants. Data collection was conducted in the childbirth room and within three days following childbirth, respectively. For tackling the research problems, participant observation and interviewing were applied. Thematic analysis was applied to the data analyzed.

RESULTS

Two themes were identified: (1) facilitators of or barriers to practice a sense of control and (2) Care needed for a sense of control. The effectiveness of a sense of control is related to energy refill, mental loading subsided, control over decisions, non-pharmacological usage, and support from the meaningful person. Care needed includes showing empathy, providing information, using complementary pain-relief strategies, and adjusting care by parturient conditions.

CONCLUSION

This study highlights the influencing factors and interventions relating to women's sense of control during childbirth with epidural analgesia. The findings suggest that many approaches, such as white noise, benefit women's sense of control after an epidural. Using non-pharmacological methods, such as a birth ball, should be appropriately regulated by situations to enhance women's sense of control. Through the assessment, education, attention to maternal needs, and recognizing the barriers to a sense of control, women will benefit from the interventions designed to improve their sense of control during childbirth.

Effect of Virtual Reality and Music Therapy on the Physiologic Parameters of Pregnant Women and Fetuses and on Anxiety Levels: A Randomized Controlled Trial

INTRODUCTION

Anxiety negatively affects pregnant women and their fetuses. It can cause misleading test readings in electronic fetal monitoring, affect the duration of the first stage of labor, and influence certain aspects related to childbirth. This study aimed to evaluate the effects of virtual reality and music therapy on anxiety levels, maternal and fetal physiologic parameters, and labor and birth outcomes.

METHODS

A total of 343 full-term pregnant women participated in a randomized controlled trial and were divided into 3 parallel groups: music therapy intervention (n = 104), virtual reality intervention (n = 124), and control (n = 115). The interventions were delivered during a nonstress test in the third trimester and during labor. Data were collected from April 2017 to May 2018. Measures included the Spielberger State-Trait Anxiety Inventory, maternal blood pressure, maternal and fetal heart rates, and labor and birth outcomes. The study was registered in the Australian New Zealand Clinical Trial Registry (ACTRN12621001647820).

RESULTS

Women in the music therapy and virtual reality groups had lower levels of anxiety after a nonstress test (P < .001), and the women were more likely to have a reactive nonstress test (P < .001) compared with the control group. After the nonstress test and intervention were complete, the music therapy and virtual reality groups had significant decreases in systolic blood pressure (P < .001), diastolic blood pressure (P < .001), and maternal heart rate (P = .003) compared with the control group. Furthermore, fetuses in the control group were more likely to experience nonreassuring fetal heart rate tracings compared with the music therapy and virtual reality groups, respectively (P = .004).

DISCUSSION

Our findings support the use of music and virtual reality during nonstress tests and labor as nonpharmacologic interventions to reduce anxiety, improve maternal and fetal physiologic parameters, and improve labor and birth outcomes. This research should be replicated in diverse perinatal settings.

Mental health promotion and protection relating to key life events and transitions in adulthood: a rapid systematic review of systematic reviews

BACKGROUND

During the decades representing working-age adulthood, most people will experience one or several significant life events or transitions. These may present a challenge to mental health.

AIM

The primary aim of this rapid systematic review of systematic reviews was to summarise available evidence on the effectiveness of interventions to promote and protect mental health relating to four key life events and transitions: pregnancy and early parenthood, bereavement, unemployment, and housing problems. This review was conducted to inform UK national policy on mental health support.

METHODS

We searched key databases for systematic reviews of interventions for working-age adults (19 to 64 years old) who had experienced or were at risk of experiencing one of four key life events. Titles and abstracts were screened by two reviewers in duplicate, as were full-text manuscripts of relevant records. We assessed the quality of included reviews and extracted data on the characteristics of each literature review. We prioritised high quality, recent systematic reviews for more detailed data extraction and synthesis.

RESULTS

The search and screening of 3997 titles/abstracts and 239 full-text papers resulted in 134 relevant studies, 68 of which were included in a narrative synthesis. Evidence was strongest and of the highest quality for interventions to support women during pregnancy and after childbirth. For example, we found benefits of physical activity and psychological therapy for outcomes relating to mental health after birth. There was high quality evidence of positive effects of online bereavement interventions and psychological interventions on symptoms of grief, post-traumatic stress, and depression. Evidence was inconclusive and of lower quality for a range of other bereavement interventions, unemployment support interventions, and housing interventions.

CONCLUSIONS

Whilst evidence based mental health prevention and promotion is available during pregnancy and early parenthood and for bereavement, it is unclear how best to support adults experiencing job loss, unemployment, and housing problems.

Nonpharmacological pain management interventions in medical and surgical abortion: A scoping review

AIMS

The study aimed to present a broad overview of the research conducted and to synthesize evidence of the utility of nonpharmacological interventions for pain management in medical and surgical abortions.

BACKGROUND

High-quality care for medical and surgical abortion requires pain to be managed effectively. However, women reported low satisfaction with pain management in abortion care.

DESIGN

A scoping review design was employed.

DATA SOURCES

No date limit was set. PubMed, Cochrane Library, EMBASE, Web of Science, CINAHL, PsycINFO, ProQuest and Scopus were searched in April 2021.

REVIEW METHODS

Arksey and O'Malley's framework was used. The Preferred Reporting Items for Systematic reviews and Meta-analysis extension-Scoping Reviews was followed.

RESULTS

Fifteen studies were included. The results revealed that support interventions, music therapy, acupoint stimulation and hypnotic analgesia were nonpharmacological interventions used to decrease abortion pain.

CONCLUSIONS

Clinical nurses, nurse managers and policymakers should attach full importance to the pain management in abortion and may use the study findings to guide the pain management practice.

Music Intervention for Pain Control in the Pediatric Population: A Systematic Review and Meta-Analysis

Music intervention (MI) has been applied as an effective adjunctive treatment for pain control in various clinical settings. However, no meta-analysis has yet been published on the analgesic effects of MI in infants and children. We performed a systematic review of PubMed, EMBASE, Web of Science, and Cochrane Library databases to identify randomized controlled trials (RCTs) with the keywords "pain" AND "music therapy" from inception to January 2022. Primary outcomes were pain intensity and vital signs. Standardized mean difference (SMD) values and the corresponding 95% confidence intervals (CIs) were computed using a random effect model. Subgroup analyses with age groups, types of pain, and music styles were conducted. A total of 38 RCTs involving 5601 participants met the selection criteria. MI significantly decreased the pain levels (SMD = -0.57, p < 0.001), both in the newborn group (p = 0.007) and in the infant/children group (p < 0.001). MI significantly reduced heart rate (SMD = -0.50, p < 0.001) and respiratory rate (SMD = -0.60, p = 0.002) and increased peripheral capillary oxygen saturation (SMD = 0.44, p < 0.001). In subgroup analyses of types of pain, MI had significant effects on prick pain (p = 0.003), chronic and procedural pain (p < 0.001), and postoperative pain (p = 0.018). As for music styles, significant analgesic effects were observed for classical music (p < 0.001), kids' music (p < 0.001), and pop music (p = 0.001), but not for world music (p = 0.196), special composition (p = 0.092), and multiple music combinations (p = 0.420). In conclusion, our analysis provides supportive evidence about the efficacy of MI, especially classical, kids', and pop music, in controlling prick, procedural, and postoperative pain in the pediatric population.

An Exploratory Study on the Acoustic Musical Properties to Decrease Self-Perceived Anxiety

Musical listening is broadly used as an inexpensive and safe method to reduce self-perceived anxiety. This strategy is based on the emotivist assumption claiming that emotions are not only recognised in music but induced by it. Yet, the acoustic properties of musical work capable of reducing anxiety are still under-researched. To fill this gap, we explore whether the acoustic parameters relevant in music emotion recognition are also suitable to identify music with relaxing properties. As an anxiety indicator, the positive statements from the six-item Spielberger State-Trait Anxiety Inventory, a self-reported score from 3 to 12, are taken. A user-study with 50 participants assessing the relaxing potential of four musical pieces was conducted; subsequently, the acoustic parameters were evaluated. Our study shows that when using classical Western music to reduce self-perceived anxiety, tonal music should be considered. In addition, it also indicates that harmonicity is a suitable indicator of relaxing music, while the role of scoring and dynamics in reducing non-pathological listener distress should be further investigated.

The effect of music on anxiety in women undergoing cesarean delivery: a systematic review and meta-analysis

OBJECTIVE

This study aimed to evaluate the effect of music on anxiety in patients undergoing cesarean delivery.

DATA SOURCES

An electronic search of PubMed, CINAHL, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials was performed from inception to November 2020.

STUDY ELIGIBILITY CRITERIA

Eligibility criteria included all randomized controlled trials of pregnant women undergoing cesarean delivery who were randomized to either the music intervention or control. Studies needed to measure preoperative, intraoperative, or postoperative anxiety via a visual analog scale, State-Trait Anxiety Inventory, or Zung Self-Rating Anxiety Scale, for inclusion. The primary outcome was intraoperative anxiety during cesarean delivery. Secondary outcomes included preoperative and postoperative anxiety, postoperative pain, postoperative opioid requirements, blood pressure, and heart rate.

STUDY APPRAISAL AND SYNTHESIS METHODS

The methodologic quality of the included studies was evaluated using the Cochrane Handbook for Systematic Reviews of Interventions. A meta-analysis was performed using the random-effects model of DerSimonian and Laird to produce a summary of treatment effects in terms of mean difference with 95% confidence intervals. A prespecified subgroup analysis of patients undergoing a scheduled or an unscheduled cesarean delivery was carried out for the main outcomes.

RESULTS

Of the 1296 studies screened, 15 met the inclusion criteria (n=613 music group vs n=748 controls). Three trials (n=217 music group vs n=215 controls) reported on intraoperative anxiety specifically. Among studies using a visual analog scale for anxiety assessment, women in the intervention group had lower intraoperative anxiety levels than the controls (mean difference, -0.54; 95% confidence interval, -0.87 to -0.20; I²=0%; n=2 studies). One trial used the State-Trait Anxiety Inventory and 1 trial used the Zung Self-Rating Anxiety Scale for intraoperative anxiety assessment. In both of these studies, music exposure was associated with lower anxiety levels when compared with the controls (State-Trait Anxiety Inventory: mean difference, -2.80; 95% confidence interval, -4.57 to -1.03; Zung Self-Rating Anxiety Scale: mean difference, -4.80; 95% confidence interval, -7.08 to -2.52). In the subgroup analyses, the same relationship persisted when the cesarean delivery was unscheduled and when the music was selected by the patient or by the study team. The effect of music on preoperative and postoperative anxiety varied depending on which anxiety assessment tool was used. Music was also associated with decreased opioid use (mean difference, -0.87; 95% confidence interval, -1.55 to -0.19; I²=0%).

CONCLUSION

In patients undergoing a cesarean delivery, music is associated with decreased intraoperative anxiety.

Interventions among Pregnant Women in the Field of Music Therapy: A Systematic Review

OBJECTIVE

 To investigate in the literature the studies on the benefits of music therapy interventions among pregnant women in the prenatal, delivery and postpartum periods.

DATA SOURCES

 The search for articles was carried out in the following electronic databases: VHL, LILACS, SciELO, Portal CAPES, PsycINFO, ERIC, PubMed/Medline, and journals specialized in this field: Revista Brasileira de Musicoterapia ("Brazilian Journal of Music Therapy") and Voices.

STUDY SELECTION

 Descriptors in Portuguese (musicoterapia, gravidez, gestantes, revisão), English (music therapy, pregnancy, pregnant women, review) and Spanish (musicoterapia, embarazo, mujeres embarazadas, revisión) were used. The search was delimited between January 2009 and June 2019. The process of selection and evaluation of the articles was performed through peer review.

DATA COLLECTION

 The following data were extracted: article title, year of publication, journal, author(s), database, country and date of collection, purpose of the study, sample size, type of care, intervention, instruments used, results, and conclusion. The data were organized in chronological order based on the year of publication of the study.

SUMMARY OF THE DATA

 In total, 146 articles were identified, and only 23 studies were included in this systematic review. The articles found indicate among their results relaxation, decreased levels of anxiety, psychosocial stress and depression, decreased pain, increase in the maternal bond, improvement in the quality of sleep, control of the fetal heart rate and maternal blood pressure, and decreased intake of drugs in the postoperative period.

CONCLUSION

 Music therapy during the prenatal, delivery and postpartum periods can provide benefits to pregnant women and newborns, thus justifying its importance in this field.

Nursing Process Addressing the Focus "Anxiety": A Scoping Review

The aim of this review was to map the body of literature on data, diagnoses and interventions addressing the nursing focus "anxiety." A scoping review methodology was employed. The Joanna Briggs guidelines for scoping reviews and PRISMA checklist for scoping reviews were followed. Electronic database searches (MEDLINE, CINAHL and Web of Science) located 829 articles. From the total of articles located, 165 were included. The nursing diagnosis "anxiety" can be considered a parent diagnosis, from which other children diagnoses are derived. Data that lead to nursing diagnoses in the anxiety domain can be divided into cognitive and somatic data. Some interventions, such as educational and music-based interventions, seem to be useful to address nursing diagnoses in the anxiety domain. The findings of this review can add substantial value for systematising the nursing process related to the focus "anxiety." Therefore, reaching consensus regarding this nursing process seems highly relevant.

The use of music as an arts-based method in migrant health research: a scoping review protocol

There is increasing recognition that people’s lived experience needs to be incorporated into health decision-making. This has led to rising imperatives for involving the public in health processes, including research. While there have been significant advances in the field, patterns of exclusion still exist in some areas, including migrant participation in health research. Migration and mobility create challenges around social inclusion and this extends to social and cultural practices used in research. There is an emerging body of literature about improving meaningful, participatory spaces for migrants’ involvement in health research using creative tools and techniques that are attuned to cultural diversity. These include the use of arts-based research methods. There is strong evidence for the use of music, particularly singing, as an effective arts-based participatory tool . The goal of this scoping review is to investigate the evidence for the use of music as an arts-based method in migrant health research. Developed by an interdisciplinary team specialising in public and patient involvement; nursing and midwifery; primary health care; and the performing arts, it aims to analyse existing evidence across disciplines that are not usually studied together, identify gaps in current knowledge and use these as a foundation to build effective strategies towards increasing access to and knowledge of participatory, arts-based methods using music in migrant health research.

Methods: The protocol for this scoping review follows the guidelines and stages set out in the JBI Reviewer’s Manual ( Peters et al., 2017), and by Levac et al, (2010), which build on the methodological framework of Arksey and O’Malley (2005). This incorporates six stages: 1) Identifying the research question; 2) Identifying relevant studies; 3) Study selection; 4) Charting the data; 5) Collating, summarising, and reporting results; and 6) Consultation.

Strategies to Mitigate Anxiety and Pain in Intrauterine Device Insertion: A Systematic Review

One barrier to the use of intrauterine devices (IUDs) as a contraceptive method is the experience of anxiety and pain during the insertion procedure. Previous reviews have focused on pharmacological methods used to relieve pain during IUD insertion; however, few similar reviews have examined non-pharmacological methods to relieve pain or strategies to reduce anxiety. The objectives of this study were to identify and categorize strategies for reducing anxiety and pain with respect to IUD insertion and the ways in which anxiety and pain were assessed. In particular, the study aimed to identify non-pharmacological interventions and studies that included anxiety as a research outcome. A literature search was conducted of all English-language studies between inception and the week of July 29, 2018 from the following online databases: Medline, Embase, Cochrane Library, and PubMed. The search revealed 426 studies after removal of duplicates, 35 of which fulfilled the inclusion criteria. A total of 29 studies were identified as assessing pharmacological interventions for the management of pain, and six studies assessed non-pharmacological interventions. Only one study included a measurement of patient anxiety during the procedure as an outcome measure. Research on non-pharmacological interventions for the management of anxiety and pain during IUD insertion is lacking. This review found that evidence for the studied pharmacological interventions is conflicting, and there is very little evidence on understanding the effectiveness of strategies to manage anxiety during the IUD insertion procedure. Further high-quality research on non-pharmacological pain and anxiety management strategies is warranted.

The effect of prenatal exposure to music on fetal movements and fetal heart rate: a pilot study

OBJECTIVE

To assess and compare fetal cardiac parameters of fetuses listening to music before and during nonstress test, only during the test or never.

STUDY DESIGN

Thirty healthy mother-fetus dyads were randomized in a 1:1:1 ratio to one of three groups: group A in which fetuses were submitted to prelistening phase (33rd + 0 to 36th + 3 week) and listening sessions during 4 nonstress tests, group B in which fetuses were submitted to listening sessions during 4 nonstress tests, and group C receiving 4 nonstress tests without any listening. We assessed mean fetal heart rate, fetal heart rate accelerations, fetal heart rate decelerations, fetal movements and uterine contractility.

RESULTS

Fetuses of the group A, who had already listened to a particular piece of music during previous sessions, had significantly increased their heart rate accelerations and movements during the music listening session of the last nonstress test. No significant changes were observed in the number of uterine contractions.

CONCLUSIONS

Our findings show that fetuses slightly respond to that music they know, but they do not significantly respond to unknown music.

Effect of music interventions on anxiety during labor: a systematic review and meta-analysis of randomized controlled trials

Background

Anxiety is commonly experienced during the delivery process and has shown to have adverse effects on maternal and infant health outcomes. Music interventions tend to reduce the effects of anxiety in diverse populations, are low cost, are easily accessible, and have high acceptability. The aim of this review and meta-analysis was to assess the effectiveness of music interventions in reducing anxiety levels among women during labor.

Methods

Seven databases from inception to the end of December, 2018, without any language or time restriction including Embase, PubMed, the Cochrane Library, the Cumulative Index to Nursing and Allied Health, PsycINFO, Airiti Library, and PerioPath: Index to Taiwan Periodical Literature were searched using key terms related to pregnancy, anxiety, and music. Randomized controlled trials that assessed the effect of music during labor and measured anxiety levels as an outcome were included. Meta-analyses were conducted to assess anxiety reduction following a music intervention compared to that after placebo treatment.

Results

A total of 14 studies that investigated a total of 1,310 participants were included in this review. The meta-analyses indicated that those in the intervention group had a significant decrease in anxiety scores (standardized mean difference = −2.40, 95% confidence interval (CI) [−3.29 to −1.52], p < 0.001; I² = 97.66%), heart rate (HR) (difference in means = −3.04 beats/min, 95% CI [−4.79 to −1.29] beats/min, p = 0.001; I² = 0.00%), systolic blood pressure (SBP) (difference in means = −3.71 mmHg, 95% CI [−7.07 to −0.35] mmHg, p = 0.031; I² = 58.47%), and diastolic blood pressure (DBP) (difference in means = −3.54 mmHg, 95% CI [−5.27 to −1.81] mmHg, p < 0.001; I² = 0.00%) as compared to the women in the control group.

Conclusions

Music interventions may decrease anxiety scores and physiological indexes related to anxiety (HR, SBP, and DBP). Music interventions may be a good non-pharmacological approach for decreasing anxiety levels during labor.

The effect of patient-selected or preselected music on anxiety during cesarean delivery: a randomized controlled trial

Background: Women undergoing cesarean delivery may have significant anxiety prior to surgery. Nonpharmacological approaches to anxiety reduction are favored in this patient population.Objective: The aim of this study was to determine the effects of patient-selected or preselected music on anxiety in parturients undergoing scheduled cesarean delivery.Materials and methods: This is a prospective, randomized controlled trial (IRB protocol #2015P002043; ClinicalTrials.gov, NCT02732964), of 150 parturients undergoing elective cesarean delivery. Parturients were randomized to patient-selected music (Pandora^®), preselected music (Mozart), or no music (control). The primary outcome was anxiety after music exposure (versus no music) in the preoperative holding room. Secondary outcomes included postoperative anxiety, postoperative pain, and patient satisfaction.Results: Baseline anxiety and anxiety following preoperative exposure did not differ in the Pandora versus control group (3.8 ± 2.4 versus 4.6 ± 2.6, mean difference -0.8 [95% CI -1.8 to 0.2], p = .12), but was lower in the Mozart group versus control group (3.5 ± 2.5 versus 4.6 ± 2.5, mean difference -1.1 [95% CI -2.2 to -0.1], p = .03). Postoperative anxiety did not differ in the Pandora versus control group (1.0 ± 1.4 versus 1.3 ± 2.0, mean difference -0.3 [95% CI -1.0 to 0.4], p = .43), or in the Mozart versus control group (0.8 ± 1.3 versus 1.3 ± 2.0, mean difference -0.5 [95% CI -1.2 to 0.2], p = .15). Postoperative pain was not different in the Pandora group versus control group (0.8 ± 1.5 versus 1.4 ± 1.9, mean difference -0.6 [95% CI -1.3 to 0.1], p = .10), but was lower in the Mozart versus control group (0.6 ± 1.3 versus 1.4 ± 1.9, mean difference -0.8 [95% CI -1.4 to -0.1], p = .03). Total patient satisfaction scores were not different among the control, Pandora, and Mozart groups.Conclusion: While preselected Mozart music results in lower anxiety prior to cesarean delivery, patient-selected Pandora music does not. Further investigation to determine how music affects patients, clinicians, and the operating room environment during cesarean delivery is warranted.Clinical trial registration: NCT02732964.
