Effect of Music on Vital Signs and Postoperative Pain

Personal versus therapist perioperative music intervention: a randomized controlled trial

INTRODUCTION

Music interventions can alleviate patient anxiety and improve post-surgical satisfaction. However, it remains uncertain whether personal music preferences affect efficacy. The authors tested whether personal music intervention with patient-selected songs played ad libitum is more effective than standard therapist-designed treatment with classical music.

METHODS

A prospective, parallel-group, single-blinded, randomized controlled trial with 229 participants (aged 18-60 years) previously scheduled for elective surgery. Data analyses followed a modified intention-to-treat principle. The patients were randomized into three groups: Standard care without music (Control), therapist-designed classic music treatment (TT), or personal music intervention with patient-selected songs played ad libitum by the patient (PI). All patients received standard post-anaesthesia care, and music intervention was started upon arrival at the post-anaesthesia care unit. Primary outcomes were anxiety and overall satisfaction at discharge. In contrast, secondary outcomes were systolic blood pressure during music intervention, the sleep quality of the night after surgery, and the occurrence of postoperative nausea and vomiting within the first 24 h after surgery.

RESULTS

Compared with therapist-designed music treatment, personal intervention decreased systolic blood pressure (T 0 : 124.3±13.7, 95% CI:121-127.7; T 20min : 117.6±10.4, 95% CI:115-120.1; T 30min : 116.9±10.6, 95% CI:114.3-119.4), prevented postoperative nausea and vomiting (Control: 55.9%, TT: 64.6%, PI: 77.6%), including severe postoperative nausea (VAS score>4; Control: 44.1%; TT: 33.8%; PI: 20.9%) and severe emesis (Frequency≥3, Control: 13.2%; TT: 7.7%; PI: 4.5%). None of the treatments affected sleep quality at night after surgery (Median, Q1-Q3, Control: 3, 1-3; TT: 3, 1-4; PI: 3, 1-3.5). Personal, but not therapist, music intervention significantly prevented anxiety (Control: 36.4±5.9, 95% CI:35.0-37.9; TT: 36.2±7.1, 95% CI: 34.4-37.9; PI: 33.8±5.6, 95% CI: 32.4-35.2) and emesis (Control: 23.9%; TT: 23.4%; PI: 13.2%) and improved patient satisfaction (Median, Q1-Q3, C: 8, 6-8; TT: 8, 7-9; PI: 8, 7-9).

CONCLUSIONS

Personal music intervention improved postoperative systolic blood pressure, anxiety, nausea, emesis, and overall satisfaction, but not sleep quality, as compared to therapist-designed classic intervention.

Effectiveness of Aromatherapy and Music Distraction in Managing Pediatric Dental Anxiety: A Comparative Study

Background

Managing a child's anxiety is most critical for the success of treatment in the pediatric dental setup. Present trend advocates the use of non-aversive behavior management techniques.

Aim and objective

To compare and evaluate the efficacy of aromatherapy using orange essential oil with that of music distraction in the management of anxious pediatric dental patients.

Design

One hundred and fifty children of the age 6–8 years were divided into three groups of 50 each and performed restorative treatment under aromatherapy, with music distraction, without aromatherapy, or music distraction, respectively. Venham's picture test and facial image scale (FIS), pulse rate, respiratory rate, and oxygen saturation were recorded before and after the procedure.

Results

Compared with controls, both the aromatherapy group and music distraction group showed significant posttreatment change in anxiety levels with respect to Venham's picture test and FIS, along with the reduction in pulse rate and respiratory rate. When compared between music distraction and aromatherapy, it did not yield statistical significance, though music distraction showed better results compared to aromatherapy.

Conclusion

Both music distraction and aromatherapy using orange essential oil are effective in anxiety management of which music distraction presents a comparatively better result. Either these non-invasive techniques alone or a combination of both may be employed in the dental setup of pediatric dentists for molding cooperative patients.

The impact of perioperative music on abdominal surgery patients' experience of postoperative pain: A systematic review and meta-analysis

OBJECTIVE

Music interventions have been analysed for their use in many surgical specialties, but they have not yet been reviewed in relation to abdominal surgery. This systematic review and meta-analysis examines the effect that listening to music perioperatively has on the postoperative pain of abdominal surgery patients.

METHODS

A systematic search of PubMed, Cochrane Library and Scopus was undertaken to identify randomised controlled trials comparing a music intervention with standard care, where self-reported postoperative pain was included as an outcome. Study quality was then assessed by the author in conjunction with Robot Reviewer software based on the Cochrane bias methodology, and a meta-analysis was performed using standard mean difference and a random-effects model.

RESULTS

Twelve studies met the inclusion criteria for review, and eight studies (2217 subjects) had appropriate data reporting to be included in the meta-analysis. Half of the reviewed studies concluded a significant positive impact on postoperative pain and the meta-analysis reinforced this hypothesis (p < 0.001). There was minimal difference in impact between intra and postoperative interventions, or between patient or researcher selected music.

CONCLUSIONS

This review supports the use of music in the perioperative period for abdominal surgery patients as a low cost adjunct to pharmaceutical pain relief.

The Effect of Perioperative Music on Medication Requirement and Hospital Length of Stay: A Meta-analysis

Objective:

To assess and quantify the effect of perioperative music on medication requirement, length of stay and costs in adult surgical patients.

Summary Background Data:

There is an increasing interest in nonpharmacological interventions to decrease opioid analgesics use, as they have significant adverse effects and opioid prescription rates have reached epidemic proportions. Previous studies have reported beneficial outcomes of perioperative music.

Methods:

A systematic literature search of 8 databases was performed from inception date to January 7, 2019. Randomized controlled trials investigating the effect of perioperative music on medication requirement, length of stay or costs in adult surgical patients were eligible. Meta-analysis was performed using random effect models, pooled standardized mean differences (SMD) were calculated with 95% confidence intervals (CI). This study was registered with PROSPERO (CRD42018093140) and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines.

Results:

The literature search yielded 2414 articles, 55 studies (N = 4968 patients) were included. Perioperative music significantly reduced postoperative opioid requirement (pooled SMD −0.31 [95% CI −0.45 to −0.16], P < 0.001, I² = 44.3, N = 1398). Perioperative music also significantly reduced intraoperative propofol (pooled SMD −0.72 [95% CI −1.01 to −0.43], P < 0.00001, I² = 61.1, N = 554) and midazolam requirement (pooled SMD −1.07 [95% CI −1.70 to −0.44], P < 0.001, I² = 73.1, N = 184), while achieving the same sedation level. No significant reduction in length of stay (pooled SMD −0.18 [95% CI −0.43 to 0.067], P = 0.15, I² = 56.0, N = 600) was observed.

Conclusions:

Perioperative music can reduce opioid and sedative medication requirement, potentially improving patient outcome and reducing medical costs as higher opioid dosage is associated with an increased risk of adverse events and chronic opioid abuse.

The effect of musical interventions in improving short-term pain outcomes following total knee replacement: a meta-analysis and systematic review

BACKGROUND

A growing number of patients continue to receive total knee replacement (TKR) surgery. Nevertheless, such surgeries result in moderate to severe postoperative pain and difficulty in managing it. Musical interventions are regarded as a type of multimodal analgesia, achieving beneficial results in other clinical treatments. This study aims to evaluate the effect of musical interventions in improving short-term pain outcomes following TKR in order to determine a more reasonable and standard way of delivering musical intervention.

METHODS

A systematic search was conducted to identify available and relevant randomized controlled trials (RCTs) regarding musical interventions compared against non-musical interventions in patients treated with TKR in Embase, MEDLINE, Cochrane Library, Web of Science, CNKI, and Wanfang Med Online up to 8 January 2020. The authors independently assessed study eligibility and risk of bias and collected the outcomes of interest to analyze. The statistical analysis was conducted using the Review Manager (RevMan) version 5.30 software.

RESULTS

Eight RCTs comprised of 555 patients satisfied the inclusion criteria and were enrolled in the present study. The results showed no significant difference between the music and control groups in pain of the visual analog scale (VAS), during postoperative recovery room, back to the ward after surgery; anxiety degree of VAS; heart rate; respiratory rate; oxygen saturation; blood pressure, systolic blood pressure, and diastolic blood pressure. Nevertheless, significant differences were observed between the two groups in average increase in continuous passive motion (CPM) angles and LF/HF ratio (one kind index of heart rate variability).

CONCLUSIONS

Musical interventions fail to demonstrate an obvious effect in improving short-term pain outcomes following TKR. A reasonable standardization of musical interventions, including musical type, outcome measures used, outcomes measured, duration, timing and headphones or players, may improve pain outcomes with certain advantages and should be further explored after TKR.

Perioperative Analgesia for Sinus and Skull-Base Surgery

Perioperative analgesic management is multifaceted, and an individualized approach should be taken with each patient. Preoperative discussion of the plan for pain control and the patient's postoperative expectations is a necessary facet for optimal outcomes of analgesia. There is the potential for significant abuse and development of dependence on opioids. Nonopioids, such as nonsteroidal anti-inflammatory drugs, acetaminophen, and gabapentinoids, provide reliable alternatives for analgesic management following sinus and skull-base surgery. There is a paucity of literature regarding perioperative pain regimens for sinus and skull-base surgery, and the authors hope that this review serves as a valuable tool for otolaryngologists.

Effects of Using Music Therapy for Patients Suffering From Dementia

The purpose of this study was to discuss the mental and physical effects of using music therapy with patients suffering with dementia. Like any type of therapy, there are guidelines for measuring the effects. Music therapy can be used as a substitute for pharmaceuticals with dementia patients. The earlier the diagnosis and the earlier treatment commences for dementia patients, the more likely the treatment will work. Music therapy can reach the part of the brain where we hold memories, which is why it is used as a treatment option for dementia patients. Alzheimer disease and dementia are among the most expensive diseases to treat. However, if the onset of dementia can be delayed, money can be saved. Medicare does not require that music therapy be offered in assisted living, nursing homes, or hospices. Areas of cost savings were identified as use of medication, length of nursing visits, and number and length of home health-aid visits, which can all be measured in total cost savings. For health care managers, it is imperative that new therapies such as music therapy be applied in health care facilities that treat dementia patients.

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.

Comparative Effect of Nature-Based Sounds Intervention and Headphones Intervention on Pain Severity After Cesarean Section: A Prospective Double-Blind Randomized Trial

Background

Non-pharmacological treatment methods are being increasingly investigated for pain prevention and relief either alone or in combination with pharmacological treatment.

Methods

The present randomized placebo-controlled trial was conducted on 57 mothers undergoing elective cesarean section over 10 months from April 2015 to February 2016. The participants were randomly assigned to three groups: control, headphone, and nature-based sounds (N-BS). The investigator recorded pain severity every eight hours after the surgery. Mothers in the headphone group used headphones for 20 minutes (without playing sounds) and mothers in the N-BS group used headphones and listened to N-BS for 20 minutes. We played pleasant nature sounds for the N-BS group using media players and headphones. Mothers' pain severity was measured immediately before the intervention and 15 and 60 minutes after the end of the intervention.

Results

The N-BS group had a significantly lower pain severity than the headphone and control groups. Statistically insignificant differences were observed between the control and headphone groups indicating that headphone only did not reduce the pain in the intervention group. These reductions were more evident progressively in 15 and 60 minutes after the end of the intervention.

Conclusions

The application of N-BS for mothers undergoing elective cesarean section promotes nursing autonomy and the notion that nurses can influence the patient's environment.

Effects of music intervention during caesarean delivery on anxiety and stress of the mother a controlled, randomised study

Background

Stress and anxiety during pregnancy and childbirth have negative consequences for both mother and child. There are indications that music has a positive effect in this situation. The present study investigates the influence of music during the caesarean on anxiety and stress of the expectant mother.

Methods

The SAMBA study is a single-centre, controlled, randomized study including 304 patients. Women in the intervention group heard music via loudspeakers from one of four self-selected genres. The control group had standard treatment without music. The caesarean was performed in regional Anesthesia. At admission, at skin incision, during skin suture and two hours after completion of surgery, different subjective (State-Trait Anxiety Inventory, visual analogue scale for anxiety) and objective parameters (salivary cortisol/amylase, heart rate, blood pressure) were collected. Mixed-factorial Analysis of variances as well as independent sample t-tests were applied for data analysis.

Results

At skin suture, significantly lower anxiety levels were reported in the intervention group regarding State anxiety (31.56 vs. 34.41; p = .004) and visual analogue scale for anxiety (1.27 vs. 1.76; p = .018). Two hours after surgery, the measured visual analogue scale for anxiety score in the intervention group was still significantly lower (0.69 vs. 1.04; p = .018). The objective parameters showed significant differences between the groups in salivary cortisol increase from admission to skin suture (12.29 vs. 16.61 nmol/L; p = .043), as well as systolic blood pressure (130.11 vs. 136.19 mmHg; p = .002) and heart rate (88.40 vs. 92.57/min; p = .049) at skin incision.

Conclusions

Music during caesarean is an easy implementable and effective way of reducing stress and anxiety of the expectant mother.

Effects of music therapy under general anesthesia in patients undergoing abdominal surgery

BACKGROUND

Music therapy, an innovative approach that has proven effectiveness in many medical conditions, seems beneficial also in managing surgical patients. The aim of this study is to evaluate its effects, under general anesthesia, on perioperative patient satisfaction, stress, pain, and awareness.

METHODS

This is a prospective, randomized, double-blind study conducted in the operating theatre of visceral surgery at Sahloul Teaching Hospital over a period of 4 months. Patients aged more than 18 undergoing a scheduled surgery under general anesthesia were included. Patients undergoing urgent surgery or presenting hearing or cognitive disorders were excluded. Before induction, patients wore headphones linked to an MP3 player. They were randomly allocated into 2 groups: Group M (with music during surgery) and group C (without music). Hemodynamic parameters, quality of arousal, pain experienced, patient's satisfaction, and awareness incidence during anesthesia were recorded.

RESULTS

One hundred and forty patients were included and allocated into 2 groups that were comparable in demographic characteristics, surgical intervention type and anesthesia duration. Comparison of these two groups regarding the hemodynamic profile found more stability in group M for systolic arterial blood pressure. A calm recovery was more often noted in group M (77.1% versus 44%, p < 10^-3). The average Visual Analog Scale (VAS) score was lower in the intervention group (33.8 ± 13.63 versus 45.1 ± 16.2; p < 10^-3). The satisfaction rate was significantly higher among the experimental group (81.4% versus 51.4%; p < 10^-3). The incidence of intraoperative awareness was higher in group C (8 cases versus 3 cases) but the difference was not statistically significant.

CONCLUSION

Music therapy is a non-pharmacological, inexpensive, and non-invasive technique that can significantly enhance patient satisfaction and decrease patients' embarrassing experiences related to perioperative stress, pain, and awareness.

Meta-analysis evaluating music interventions for anxiety and pain in surgery

BACKGROUND

This study aimed to evaluate anxiety and pain following perioperative music interventions compared with control conditions in adult patients.

METHODS

Eleven electronic databases were searched for full-text publications of RCTs investigating the effect of music interventions on anxiety and pain during invasive surgery published between 1 January 1980 and 20 October 2016. Results and data were double-screened and extracted independently. Random-effects meta-analysis was used to calculate effect sizes as standardized mean differences (MDs). Heterogeneity was investigated in subgroup analyses and metaregression analyses. The review was registered in the PROSPERO database as CRD42016024921.

RESULTS

Ninety-two RCTs (7385 patients) were included in the systematic review, of which 81 were included in the meta-analysis. Music interventions significantly decreased anxiety (MD -0·69, 95 per cent c.i. -0·88 to -0·50; P < 0·001) and pain (MD -0·50, -0·66 to -0·34; P < 0·001) compared with controls, equivalent to a decrease of 21 mm for anxiety and 10 mm for pain on a 100-mm visual analogue scale. Changes in outcome corrected for baseline were even larger: MD -1·41 (-1·89 to -0·94; P < 0·001) for anxiety and -0·54 (-0·93 to -0·15; P = 0·006) for pain. Music interventions provided during general anaesthesia significantly decreased pain compared with that in controls (MD -0·41, -0·64 to -0·18; P < 0·001). Metaregression analysis found no significant association between the effect of music interventions and age, sex, choice and timing of music, and type of anaesthesia. Risk of bias in the studies was moderate to high.

CONCLUSION

Music interventions significantly reduce anxiety and pain in adult surgical patients.

Music as Medicine: The Therapeutic Potential of Music for Acute Stroke Patients

Nurses caring for patients with acute stroke are likely to administer both music and medication with therapeutic intent. The administration of medication is based on accumulated scientific evidence and tailored to the needs of each patient. However, the therapeutic use of music is generally based on good intentions and anecdotal evidence. This review summarizes and examines the current literature regarding the effectiveness of music in the treatment of critically ill patients and the use of music in neurologically injured patients. The rationale for hypothesis-driven research to explore therapeutic music intervention in acute stroke is compelling.

The influence of ambient scent and music on patients' anxiety in a waiting room of a plastic surgeon

OBJECTIVE

This study investigates the influence of ambient scent and music, and their combination, on patients' anxiety in a waiting room of a plastic surgeon.

BACKGROUND

Waiting for an appointment with a plastic surgeon can increase a patient's anxiety. It is important to make the waiting time before an appointment with the surgeon more pleasant and to reduce the patient's anxiety. Ambient environmental stimuli can influence people's mood, cognition, and behavior. This experimental study was performed to test whether ambient scent and music can help to reduce patients' anxiety.

METHODS

Two pre-studies (n = 21) were conducted to measure the subjective pleasantness and arousal of various scents and music styles. Scent and music that scored high on pleasantness and low on arousal were selected for the main study. The field experiment (n = 117) was conducted in the waiting room of a German plastic surgeon. The patients' levels of anxiety were measured in four conditions: (1) without scent and music, (2) with lavender scent; (3) with instrumental music; (4) with both scent and music.

RESULTS

When used separately, each of the environmental factors, music and scent, significantly reduced the level of patient's anxiety compared to the control condition. However, the combination of scent and music was not effective in reducing anxiety.

CONCLUSIONS

Our results suggest that ambient scent and music can help to reduce patients' anxiety, but they should be used with caution. Adding more ambient elements to environment could raise patients' level of arousal and thus increase their anxiety.

KEYWORDS

Healing environments, patient, patient-centered care, quality care, satisfaction.

Music in Obstetrics: An Intervention Option to Reduce Tension, Pain and Stress

In recent years, the effect of music interventions and music therapy has experienced increased attention in the literature. It has been shown that music has positive effects on cognitive and physical performance, such as concentration and endurance, as well as on psychological parameters, such as anxiety and relaxation. Studies within the context of medicine in particular are increasingly indicating that music may be used as an intervention for relief against anxiety, stress and pain. Music is therefore seen in actual practice as a supplement to conventional pharmacological and non-pharmacological forms of treatment - and the trend is rising. Studies involving music interventions in the field of obstetrics have shown, amongst other things, that music improves the ability to relax during pregnancy and can reduce anxiety. It was also discovered that during childbirth music interventions resulted in a reduction of pain and stress. Music also has the effect of reducing stress, pain and anxiety in expectant mothers during deliveries by caesarean section. This review intends to provide an overview of the literature on music interventions in the field of obstetrics and to give a resume on the current state of research around the topic of music in relation to pregnancy, spontaneous deliveries and caesarean sections. Furthermore, the relevance of music for everyday obstetrics will be illustrated.

Management of Postoperative Pain: A Clinical Practice Guideline From the American Pain Society, the American Society of Regional Anesthesia and Pain Medicine, and the American Society of Anesthesiologists' Committee on Regional Anesthesia, Executive Committee, and Administrative Council

Most patients who undergo surgical procedures experience acute postoperative pain, but evidence suggests that less than half report adequate postoperative pain relief. Many preoperative, intraoperative, and postoperative interventions and management strategies are available for reducing and managing postoperative pain. The American Pain Society, with input from the American Society of Anesthesiologists, commissioned an interdisciplinary expert panel to develop a clinical practice guideline to promote evidence-based, effective, and safer postoperative pain management in children and adults. The guideline was subsequently approved by the American Society for Regional Anesthesia. As part of the guideline development process, a systematic review was commissioned on various aspects related to various interventions and management strategies for postoperative pain. After a review of the evidence, the expert panel formulated recommendations that addressed various aspects of postoperative pain management, including preoperative education, perioperative pain management planning, use of different pharmacological and nonpharmacological modalities, organizational policies, and transition to outpatient care. The recommendations are based on the underlying premise that optimal management begins in the preoperative period with an assessment of the patient and development of a plan of care tailored to the individual and the surgical procedure involved. The panel found that evidence supports the use of multimodal regimens in many situations, although the exact components of effective multimodal care will vary depending on the patient, setting, and surgical procedure. Although these guidelines are based on a systematic review of the evidence on management of postoperative pain, the panel identified numerous research gaps. Of 32 recommendations, 4 were assessed as being supported by high-quality evidence, and 11 (in the areas of patient education and perioperative planning, patient assessment, organizational structures and policies, and transitioning to outpatient care) were made on the basis of low-quality evidence.

PERSPECTIVE

This guideline, on the basis of a systematic review of the evidence on postoperative pain management, provides recommendations developed by a multidisciplinary expert panel. Safe and effective postoperative pain management should be on the basis of a plan of care tailored to the individual and the surgical procedure involved, and multimodal regimens are recommended in many situations.

The Effects of Music on Pain: A Meta-Analysis

BACKGROUND

Numerous meta-analyses have been conducted on the topic of music and pain, with the latest comprehensive study published in 2006. Since that time, more than 70 randomized controlled trials (RCTs) have been published, necessitating a new and comprehensive review.

OBJECTIVE

The aim of this meta-analysis was to examine published RCT studies investigating the effect of music on pain.

METHODS

The present study included RCTs published between 1995 and 2014. Studies were obtained by searching 12 databases and hand-searching related journals and reference lists. Main outcomes were pain intensity, emotional distress from pain, vital signs, and amount of analgesic intake. Study quality was evaluated according to the Cochrane Collaboration guidelines.

RESULTS

Analysis of the 97 included studies revealed that music interventions had statistically significant effects in decreasing pain on 0-10 pain scales (MD = -1.13), other pain scales (SMD = -0.39), emotional distress from pain (MD = -10.83), anesthetic use (SMD = -0.56), opioid intake (SMD = -0.24), non-opioid intake (SMD = -0.54), heart rate (MD = -4.25), systolic blood pressure (MD = -3.34), diastolic blood pressure (MD = -1.18), and respiration rate (MD = -1.46). Subgroup and moderator analyses yielded additional clinically informative outcomes.

CONCLUSIONS

Considering all the possible benefits, music interventions may provide an effective complementary approach for the relief of acute, procedural, and cancer/chronic pain in the medical setting.

Effects of Art on Surgical Patients: A Systematic Review and Meta-analysis

OBJECTIVES

The aim of the study was to assess the effect of art including ambient features such as music, interior design including visual art, and architectural features on health outcomes in surgical patients.

BACKGROUND

Healing environments can have a positive influence on many patients, but data focusing on art in surgical patients remain scarce.

METHODS

We conducted a systematic search following the PRISMA guidelines from January 2000 to October 2014 on art in surgical patients. For music interventions, we pooled controlled studies measuring health outcomes (eg, pain, anxiety, blood pressure, and heart rate) in a meta-analysis. For other art forms (ambient and architectural features and interior design), we did a narrative review, also including nonsurgical patients, and looked for examples covering 3 countries.

RESULTS

Our search identified 1101 hits with 48 studies focusing on art in surgical patients: 47 studies on musical intervention and 1 on sunlight. The meta-analysis of these studies disclosed significant effects for music on pain after surgery, anxiety, systolic blood pressure, and heart rate, when compared with control groups without music. Effects of music were larger with self-selected music, and lower in surgical interventions performed under general anesthesia. Interior design features such as nature images and more spacious rooms, and architectural features providing more sunlight had positive effects on anxiety and postoperative pain.

CONCLUSIONS

Self-selected music for surgical patients is an effective and low-cost intervention to enhance well being and possibly faster recovery. Although potentially very important, the impact of environmental features and spacious architecture with wide access to sunlight remains poorly explored in surgery. Further experimental research is needed to better assess the magnitude of the impact and cost effectiveness.

Influence of music and its genres on respiratory rate and pupil diameter variations in cats under general anaesthesia: contribution to promoting patient safety

OBJECTIVES

The aims of the study were to recognise if there is any auditory sensory stimuli processing in cats under general anaesthesia, and to evaluate changes in respiratory rate (RR) and pupillary diameter (PD) in anaesthetised patients exposed to different music genres, while relating this to the depth of anaesthesia.

METHODS

A sample of 12 cats submitted for elective ovariohysterectomy was exposed to 2 min excerpts of three different music genres (classical [CM], pop [PM] and heavy metal [HM]) at three points during surgery (T1 = coeliotomy; T2 = ligature placement and transection of the ovarian pedicle; T3 = ligature placement and transection of the uterine body). A multiparametric medical monitor was used to measure the RR, and a digital calliper was used for PD measurement. Music was delivered through headphones, which fully covered the patient's ears. P values   <0.05 were considered to be statistically significant.   

RESULTS

Statistically significant differences between stimuli conditions for all surgical points were obtained for RR (T1, P = 0.03; T2, P = 0.00; T3, P = 0.00) and for PD (T1, P = 0.03; T2, P = 0.04; T3, P = 0.00). Most individuals exhibited lower values for RR and PD when exposed to CM, intermediate values to PM and higher values to HM.

CONCLUSIONS AND RELEVANCE

The results suggest that cats under general anaesthesia are likely to perform auditory sensory stimuli processing. The exposure to music induces RR and PD variations modulated by the genre of music and is associated with autonomic nervous system activity. The use of music in the surgical theatre may contribute to allowing a reduced anaesthetic dose, minimising undesirable side effects and thus promoting patient safety.

Effect of music on postoperative pain in patients under open heart surgery

Background:

Music, as a non-pharmacological and inexpensive nursing intervention, can be used easily as a complementary technique in reducing pain along with other methods. While some studies have demonstrated pain to decrease after music, others found music to be ineffective on pain.

Objectives:

The aim of this study was to investigate the effect of music on postoperative pain in patients under open heart surgery.

Patients and Methods:

A quasi-experimental study was performed on 60 patients under open heart surgery referred to ICU of Shahid Beheshti hospital in Kashan city. Patients were randomly divided into two groups including experimental and control groups. Patients in music group listened to nonverbal music for 30 minutes after surgery by headphones. The control group did not receive any intervention other than routine care. Before and after intervention, pain intensity was measured and recorded by visual analog scale in two groups. Data was analyzed using Chi-Square and t-tests.

Results:

Before intervention, the mean of pain intensity was 6.32 ± 0.21 and 6.10 ± 0.21 for experimental and control groups, respectively; and the difference was not significant (P = 0.21). After intervention, the mean of pain intensity was 3.11 ± 0.12 and 5.81 ± 0.38 for experimental and control groups, respectively; and the difference was significant (P = 0.04).

Conclusions:

Listening to the relaxant music can reduce postoperative pain. It is suggested that relaxant music be used as a complementary method in patients in order to reduce prospective pain.

Association between central auditory processing mechanism and cardiac autonomic regulation

Background

This study was conducted to describe the association between central auditory processing mechanism and the cardiac autonomic regulation.

Methods

It was researched papers on the topic addressed in this study considering the following data bases: Medline, Pubmed, Lilacs, Scopus and Cochrane. The key words were: “auditory stimulation, heart rate, autonomic nervous system and P300”.

Results

The findings in the literature demonstrated that auditory stimulation influences the autonomic nervous system and has been used in conjunction with other methods. It is considered a promising step in the investigation of therapeutic procedures for rehabilitation and quality of life of several pathologies.

Conclusion

The association between auditory stimulation and the level of the cardiac autonomic nervous system has received significant contributions in relation to musical stimuli.

Effects of music relaxation video on pain and anxiety for women with gynaecological cancer receiving intracavitary brachytherapy: a randomised controlled trial

The purpose of this study was to explore the effects of music relaxation video on pain severity, opioid utilisation, and anxiety experienced by women with gynaecological cancer undergoing intracavitary brachytherapy. A two-group randomised controlled trial was conducted in an academic comprehensive cancer centre. Sixty women were randomly assigned to either an experimental group ( n = 31) that watched a 30-minute music relaxation video four times (total 120 minutes) or a control group ( n = 29) that received standard nursing care during the first 44 hours of the intracavitary brachytherapy. Data were collected to evaluate the effects on pain severity, opioid utilisation and anxiety between groups. Pain scores were measured before and after patients watched the 30-minute music relaxation video and anxiety scores were measured following the video. The amount of opioid consumption was recorded during the 44-hour treatment. Data were tested using ANOVA and t-test. Perceived pain reduction was statistically significant in the experimental group ( p = 0.027), but this did not translate into lower total consumption of opioids between the two study groups. Anxiety level reduction was statistically significant in the experimental group ( p = 0.001). Music relaxation videos hold promise to be used in conjunction with standard pharmacologic therapy to reduce perceived pain and anxiety levels during the treatments.

Music can effectively reduce pain perception in women rather than men

Objective: Nowadays music is used to decrease pain and increase relaxation in clinical settings. It is hypothesized that music can affect women more easily than men. We assessed the effect of two types of music (Iranian folkloric and preferred music) on pain tolerance and pain rating in cold pressor test.

Methodology: A consecutive sample of 50 healthy Iranian medical students was enrolled. They reported pain tolerance and pain rating in cold pressor test in three different musical conditions served as the outcome measures. The results were analyzed with repeated measurement analysis of variance.

Result: Mean tolerance time was significantly higher in preferred music compared to Iranian folkloric music (F (1,48) =25.44, p=0.0001) and no music (F(1,48)=3.51, p=0.0001) conditions. There was a significant interaction when tolerance time in no music condition was compared to preferred music condition, regarding sex; Tolerance time increased more in females (F(1,48)=5.53, p=0.023). The results also indicated that pain ratings, regardless of sex, were different in three musical conditions (F(1.7,81.34)=15.37, p=0.0001).

Conclusion: Music distracted attention from pain and Women can be impressed and distracted more easily by music.

Role of anxiety in the comfort of nonsedated average-risk screening sigmoidoscopy

OBJECTIVES

The aim of this prospective study was to assess the role of generalized anxiety disorder in the comfort of nonsedated, average-risk screening sigmoidoscopy.

METHODS

Patients were asked to complete a screening questionnaire before undergoing average-risk colon cancer screening with nonsedated sigmoidoscopy. The questionnaire included demographic information and a series of Likert-based and visual analog scales designed to assess patient comfort, procedural symptom severity, and satisfaction. The Primary Care Evaluation of Mental Disorders questionnaire was used to assess for generalized anxiety disorder. Comfort levels and postprocedural symptom severity were recorded immediately after the procedure and 1 week postprocedure. χ and t tests were used to analyze the data.

RESULTS

Eighty-one patients were enrolled in the study. Twenty-seven patients tested positive for anxiety (high anxiety), whereas 54 tested negative (low anxiety). There were no differences in anxiety according to sex (P = 0.53), or age (P = 0.32). There was no difference in reaching the splenic flexure between high- and low-anxiety patients (P = 0.15); however, pairwise comparisons revealed patients with high anxiety reported significantly higher levels of abdominal pain after the procedure (P < 0.01) and still recalled higher pain from the procedure 1 week later (P < 0.01) than those patients with low anxiety scores. Furthermore, those patients with high anxiety reported significantly more procedure-related cramping and bloating both immediately after the procedure and again 1 week later (P < 0.01). Finally, patients with high anxiety reported the procedure as being more uncomfortable 1 week later, when compared with low-anxiety patients (P = 0.01).

CONCLUSIONS

The level of anxiety correlated directly to pain and discomfort postprocedure and related inversely to the level of satisfaction. Better management of anxiety may lead to better procedural comfort in nonsedated procedures.

Respostas fisiológicas de recém-nascidos pré-termo submetidos à musicoterapia clássica

OBJETIVO: Avaliar o efeito da musicoterapia nas respostas fisiológicas de recém-nascidos pré-termo hospitalizados. MÉTODOS: Ensaio clínico não controlado realizado com 12 recém-nascidos pré-termo, com idade gestacional <36 semanas, em respiração espontânea. Os pacientes foram submetidos a sessões de musicoterapia durante 15 minutos duas vezes ao dia, nos períodos matutino e vespertino, por três dias consecutivos. As variáveis: frequências cardíaca e respiratória, saturação de oxigênio, pressões arteriais sistólica e diastólica e temperatura corporal foram analisadas antes e imediatamente após a sessão de musicoterapia. RESULTADOS: Observou-se a diminuição da frequência cardíaca imediatamente após a segunda sessão de musicoterapia (t pareado; p=0,002) e o aumento ao final da terceira sessão, em relação ao início (t pareado; p=0,005). A frequência respiratória diminuiu após a musicoterapia na quarta e quinta sessões (t pareado; p=0,01 e 0,03, respectivamente). Em relação à saturação de oxigênio, houve aumento após a quinta sessão de musicoterapia (p=0,008). A análise de variância realizada entre as seis sessões, após o cálculo da média das diferenças entre os parâmetros iniciais e finais, demonstrou que o ganho médio de saturação de oxigênio na quinta sessão foi maior do que na sexta (teste de Tukey após análise de variância; p=0,04). CONCLUSÕES: A musicoterapia pode modificar em curto prazo as respostas fisiológicas de recém-nascidos pré-termo hospitalizados.

Effects of music listening on adult patients' pre-procedural state anxiety in hospital

EXECUTIVE SUMMARY:

BACKGROUND

Anticipation of an invasive procedure in hospital is likely to provoke feelings of anxiety and stress in patients. An unfamiliar environment, loss of control, perceived or actual physical risk, dependence on strangers and separation from friends and family are all factors that can contribute to the development of such feelings. Recently, there has been considerable interest in the anxiolytic potential of music listening in a variety of clinical settings, yet thus far, little is known about the impact of music listening on the pre-procedural patient population. A systematic review of all literature to date was indicated to improve understanding of outcomes and impact of music listening on pre-procedural anxiety, thus helping nurses decide whether or not to incorporate music listening into practice and to highlight a need, or otherwise, for a related primary research agenda.

OBJECTIVE

The objective of this review was to determine the best available evidence on the effectiveness of music listening in reducing adult hospital patients' pre-procedural state anxiety.

INCLUSION CRITERIA

Types of studies This review included randomised controlled trials and quasi-experimental research designs that examined the efficacy of music listening in reducing state anxiety among pre-procedural hospital patients published between January 1985 and February 2006. The search was limited to publications after 1985 to coincide with the increasing interest and use of complementary therapies within health care during the 1980s and 1990s. Types of participants Participants of interest to the review were adult day patients, ambulatory patients and inpatients who were about to undergo any type of clinical procedure. Types of intervention The review focused on studies that investigated pre-procedural music listening employed and prescribed as a potentially therapeutic activity. It excluded any other form of music therapy. Types of outcome measures The primary outcome measures examined were alterations in state anxiety and a variety of physiological variables such as blood pressure and respiration and heart rates.

SEARCH STRATEGY

A search for published and unpublished literature between January 1985 and February 2006 was conducted using all major electronic databases. A three-step search strategy was devised which consisted of using high-precision MeSH terminology and keywords to ensure that all material relevant to the review was captured. CRITICAL APPRAISAL: The methodological quality of included studies was assessed by two reviewers, who appraised each study independently, using the standard Joanna Briggs Institute (JBI) critical appraisal tools.

DATA EXTRACTION AND SYNTHESIS

Data were extracted from the studies that were identified as meeting the criteria for methodological quality using a data-extraction tool developed for the review. Studies were grouped by outcome measure and summarised using tabular and narrative formats.

RESULTS

The review demonstrated that state anxiety is defined and measured using both psychological and physiological parameters. Music listening had a consistently positive and statistically significant effect on reducing psychological parameters of pre-procedural state anxiety. However, the results from the measurement of various pre-procedural physiological parameters failed to reveal any consistent positive changes in patients who had listened to music. This calls into question the adequacy of the theories in this area which link anxiety and the automated and central nervous systems and the effect that music listening may have on these processes and physiological responses.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

1 In order to reduce anxiety, it is likely that patients will benefit psychologically from having the opportunity to listen to music in the immediate pre-procedural period. 2 Patients do not appear to experience any alteration in physiological status as a result of listening to music. 3 Further research is indicated in order to replicate existing studies, to strengthen the evidence to support such interventions and to establish intervention parameters. 4 Further research is needed analysing the physiological mechanisms by which music listening is believed to reduce state anxiety and the contribution of the automated and other nervous systems to this reduction.

Sensory environment on health-related outcomes of hospital patients

BACKGROUND

Hospital environments have recently received renewed interest, with considerable investments into building and renovating healthcare estates. Understanding the effectiveness of environmental interventions is important for resource utilisation and providing quality care.

OBJECTIVES

To assess the effect of hospital environments on adult patient health-related outcomes.

SEARCH METHODS

We searched: the Cochrane Central Register of Controlled Trials (last searched January 2006); MEDLINE (1902 to December 2006); EMBASE (January 1980 to February 2006); 14 other databases covering health, psychology, and the built environment; reference lists; and organisation websites. This review is currently being updated (MEDLINE last search October 2010), see Studies awaiting classification.

SELECTION CRITERIA

Randomised and non-randomised controlled trials, controlled before-and-after studies, and interrupted times series of environmental interventions in adult hospital patients reporting health-related outcomes.

DATA COLLECTION AND ANALYSIS

Two review authors independently undertook data extraction and 'Risk of bias' assessment. We contacted authors to obtain missing information. For continuous variables, we calculated a mean difference (MD) or standardized mean difference (SMD), and 95% confidence intervals (CI) for each study. For dichotomous variables, we calculated a risk ratio (RR) with 95% confidence intervals (95% CI). When appropriate, we used a random-effects model of meta-analysis. Heterogeneity was explored qualitatively and quantitatively based on risk of bias, case mix, hospital visit characteristics, and country of study.

MAIN RESULTS

Overall, 102 studies have been included in this review. Interventions explored were: 'positive distracters', to include aromas (two studies), audiovisual distractions (five studies), decoration (one study), and music (85 studies); interventions to reduce environmental stressors through physical changes, to include air quality (three studies), bedroom type (one study), flooring (two studies), furniture and furnishings (one study), lighting (one study), and temperature (one study); and multifaceted interventions (two studies). We did not find any studies meeting the inclusion criteria to evaluate: art, access to nature for example, through hospital gardens, atriums, flowers, and plants, ceilings, interventions to reduce hospital noise, patient controls, technologies, way-finding aids, or the provision of windows. Overall, it appears that music may improve patient-reported outcomes such as anxiety; however, the benefit for physiological outcomes, and medication consumption has less support. There are few studies to support or refute the implementation of physical changes, and except for air quality, the included studies demonstrated that physical changes to the hospital environment at least did no harm.

AUTHORS' CONCLUSIONS

Music may improve patient-reported outcomes in certain circumstances, so support for this relatively inexpensive intervention may be justified. For some environmental interventions, well designed research studies have yet to take place.

Effects of music on depression and sleep quality in elderly people: A randomised controlled trial

OBJECTIVES

To determine the effect of music on sleep quality in elderly people. In addition, we aimed to examine if there were effects on vital signs and depression levels.

BACKGROUND

Sleep disturbances and depression are common in older people, and their impacts on this group, along with its conventional treatment, merit our attention as our population ages. Conventional pharmacological methods might result dependence and impairment in psychomotor and cognitive functioning. Listening to music, which is a non-pharmacological method, might reduce depression and promote sleep quality.

DESIGN

A randomised controlled study was conducted during the period December 2006 to January 2007.

SETTING

At participants' homes in Hong Kong.

PARTICIPANTS

In total, 42 elderly people (21 using music and 21 controls) completed the study after being recruited in one community services centre.

INTERVENTION

Participants listened to their choice of music for 30min per week, for 4 weeks.

MAIN OUTCOME MEASURES

Blood pressure, heart rate, depression levels and sleep quality variables were collected once a week for 4 weeks.

RESULTS

In the experimental group, there were statistically significant reductions in geriatric depression scores and sleep quality at week 4. In the control group, there were no statistically significant reductions in depression and improvement of sleep quality over the 4 weeks. However, for all the outcome measures, no significant differences were found between groups over the 4 weeks.

CONCLUSIONS

The findings contribute to knowledge about the effectiveness of soft slow music used as an intervention to improve depression and sleep quality in elderly people. Whilst there were no statistical differences between groups, there was some indication that music yielder higher improvement on some of the parameters, which are worthy of further investigation in larger trials.

O artigo tem como objetivo refletir sobre as contribuições do uso da música nos cuidados paliativos e na humanização do cuidado da pessoa fora de possibilidades terapêuticas de cura. Com esse propósito, foi realizada pesquisa bibliográfica, mediante busca eletrônica de artigos indexados em bases de dados e por varredura manual dos periódicos não indexados considerados relevantes. A pesquisa mostra que o uso da música nos processos saúde-doença-cuidado pode promover conforto e qualidade de vida para a pessoa adoecida e ser um recurso de ajuda na relação da família com a despedida de seu ente querido. Pode também auxiliar na manutenção de uma equipe de saúde saudável e integrada.

The anxiety- and pain-reducing effects of music interventions: a systematic review

Musical interventions have been used in health care settings to reduce patient pain, anxiety, and stress, although the exact mechanism of these therapies is not well understood. This article provides a systematic review of 42 randomized controlled trials of the effects of music interventions in perioperative settings. Music intervention had positive effects on reducing patients' anxiety and pain in approximately half of the reviewed studies. Further research into music therapy is warranted in light of the low cost of implementation and the potential ability of music to reduce perioperative patient distress.
