Music therapy and psychological-clinical impact in surgery: a systematic review

Effect of Music Therapy on Anxiety in Pregnancy: A Systematic Review of Randomized Controlled Trials

Pregnancy can heighten anxiety levels, impacting both maternal and fetal well-being. This systematic review synthesizes evidence from 33 randomized controlled trials exploring the effects of music therapy on anxiety in pregnant women. The studies included diverse populations, ranging from women undergoing in vitro fertilization (IVF) to those facing high-risk pregnancies. Music therapy interventions varied widely, including virtual reality experiences, classical music, lullabies, and patient-selected music, administered at different pregnancy stages such as IVF treatments, elective cesarean sections, and high-risk hospitalizations. The findings consistently demonstrated that music therapy significantly reduces anxiety levels in pregnant women. Positive outcomes included reductions in both state and trait anxiety, improved pregnancy rates, and enhanced maternal-fetal parameters. Additionally, music therapy showed promise in reducing anxiety during labor, cesarean deliveries, and high-risk hospital stays. These varied interventions and their positive outcomes highlight the potential of music therapy as an effective, non-pharmacological approach to managing pregnancy-related anxiety. This review provides a comprehensive overview of the existing evidence on music therapy's efficacy in alleviating anxiety during pregnancy. It underscores the need for further research to standardize interventions and incorporate music therapy into routine prenatal care. By enhancing the overall well-being of expectant mothers, music therapy could become a valuable adjunct to conventional prenatal care practices.

Effects of Music Therapy on Postoperative Pain Perception in Patients Undergoing Abdominal Surgeries Under General Anesthesia: A Prospective Controlled Randomized Comparative Clinical Study

Background Music therapy has been shown to reduce the need for sedation and analgesics, as well as lower plasma cortisol and epinephrine levels in patients undergoing regional anesthesia. This study evaluates the efficacy of perioperative music therapy in reducing pain perception and its impact on cortisol levels. Materials and methods This prospective randomized control trial was conducted at the tertiary care center in Western Maharashtra. Sixty adult patients (males/females) undergoing elective lower abdomen surgery were included and randomized equally into two groups to listen to music using headphones at a preselected volume (Group M) or to use only headphones without any music played (Group C) for 2 hours in the preoperative, intraoperative, and postoperative periods. Demographic information, anthropometric (height, weight), and biochemical (serum cortisol) measurements were performed. American Society of Anesthesiologists (ASA) grades 1 and 2, and patients aged 18 to 65 years were included. Pain perception was assessed using the Visual Analog Scale (VAS). Results The demographic data, including mean age, BMI, ASA status, average duration of anesthesia, and average duration of surgery, were comparable between the two groups. Group M showed improved control of systolic blood pressure (SBP) at 10- and 30-minute post-induction of general anesthesia and had a significantly lower VAS score (p < 0.05). Additionally, patient satisfaction was higher in Group M (81.4%) compared to Group C (51.4%) with a p-value of < 0.05. Intraoperative awareness was non-significant between the groups. Conclusion Music therapy is a safe, cost-effective, and efficacious method for reducing pain perception and can be used in conjunction with other treatments for postoperative pain management.

Broad Responses and Attitudes to Having Music in Surgery (The BRAHMS Study): An Australia and Aotearoa New Zealand Perspective

Background

Surgery is a stressful exercise, and the experience of occupational stress may have impacts on surgical performance, and surgeon well-being. Music is played in operating theatres (OTs) throughout the world, and while it may improve surgical performance, and reduce clinician stress within the OT, concerns exist over its distracting and noise-creating properties.

Methods

In this prospective observational study, between May to August 2022, Vascular, General and Paediatric surgeons and registrars in Australia and Aotearoa New Zealand (AoNZ) responded to a survey investigating the way they use music, and their perceptions and attitudes towards its effect on the OT environment. Binomial logistic regression and Chi squared tests of association were performed, accepting p < 0.05 as significant.

Results

In this cohort of 120 surgeons, 45 % were vascular specialists, 30 % were female and 59 % were consultant surgeons. The most commonly preferred music genres were easy listening and pop. Over 75 % of surgeons enjoyed having music in their OTs with the majority reporting it improved their temperament, how mentally fatiguing a procedure felt and how anxious or stressed they felt. Vascular surgeons were more likely to believe music had a positive influence on communication than their general and paediatric surgery colleagues (p < 0.01). Registrars had significantly higher odds of believing music had a positive effect on their temperament, and how stressed and anxious they felt when operating, when compared to consultants (p < 0.05).

Conclusions

This study provides a window into the surgeons' use of and attitudes towards intra-operative background music and its effect on stress and cognitive load in Australia and AoNZ. While overall, music is viewed positively by this cohort, there was some difference seen across specialties and level of experience. Further subjective and objective data in this field may provide useful information to guide hospital policy and inform pathways for clinician wellbeing.

Effect of Preoperative Music Therapy Versus Intravenous Midazolam on Anxiety, Sedation and Stress in Stomatology Surgery: A Randomized Controlled Study

BACKGROUND

Patients undergoing surgery and general anesthesia often experience anxiety, fear and stress, with negative bodily responses. These may be managed by the pre-procedural application of anxiolytic, analgesic, and anesthetic drugs that have, however, potential risks or side effects. Music therapy (MT) can be used as a complementary no-drug intervention alongside standard surgical care before, during and after medical procedures. The aim of this study was to evaluate the effects of preoperative MT intervention compared to premedication with midazolam on levels of anxiety, sedation and stress during general anesthesia for elective stomatology surgery.

METHODS

A two-arm randomized and controlled single-center, parallel-group, pre-post event study was conducted. In total, 70 patients affected by stage I or II (both clinically and instrumentally N0) micro-invasive oral cancer and undergoing elective surgery under general anesthesia were assigned to the control group (CG) or to the music therapy group (MTG). MTG patients received preoperative music therapy intervention (MT) from a certified music therapist before surgery, while the CG patients did not receive MT but instead received premedication with intravenous midazolam, 0.02 mg/kg. Anesthesia was the same in both groups. The systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were recorded at the entrance to the operating room, just before the induction of anesthesia and every 5 min until the end of surgery. An anxiety visual analogues scale (A-VAS) was used to evaluate the level of anxiety. The bispectral index (BIS) monitor was used to measure the depth of sedation just before and 10 min after both music intervention and midazolam administration. Stress response was assessed 5 min before and 20 min after surgery via the control of plasma prolactin (PRL), growth hormone (GH), and cortisol levels. The patient global impression of satisfaction (PGIS) was tested 1 h after surgery. Participants in the MTG were asked to answer 3 questions concerning their experience with MT.

RESULTS

No statistical differences among the PRL, GH and cortisol levels between the two groups were registered before and after the treatment, as well as for PAS, PAD and HR. Significant differences in the A-VAS scores between the MTG and CG (p < 0.01) was observed. Compared to the CG, MTG patients had a statistically significantly lower BIS score (p = 0.02) before induction. A PGIS score of 86.7% revealed that patients in the MTG were very satisfied, versus 80% in the CG (p < 0.05).

CONCLUSION

Preoperative music therapy could be an alternative to intravenous midazolam when aiming to promote a preoperative and post-operative state of anxiolysis and sedation in stomatology surgery, even if no differences were found in terms of the surgery-related stress response according to physiological and hormonal determinations.

Online group music therapy: proactive management of undergraduate students' stress and anxiety

Introduction

In alignment with the World Health Organization's (WHO) goal to provide comprehensive and integrated mental health services in community-based settings, this randomized control trial explored the efficacy of online group music therapy as a proactive intervention for reducing stress and anxiety in university students who do not necessarily have a diagnosis.

Methods

The study took place during COVID-19 restrictions. Students who volunteered were randomly assigned to 6 weeks of weekly (1) online active group music therapy, (2) online receptive group music therapy, (3) online group verbal therapy (standard of care), or (4) no-intervention (control group). Students rated their stress (Likert scale) and anxiety [State-Trait Anxiety Inventory, State version (STAI-S)], and provided heart rate variability (HRV) using a phone app, pre and post each therapy session.

Results

STAI-S and Likert stress scores significantly reduced from pre to post 45-min online music therapy sessions, with moderate evidence that these changes did not differ from the standard of care (verbal therapy). HRV results were not analyzed statistically as HRV collection was likely compromised due to challenges of remote collection. Students completed the Perceived Stress Scale (PSS) and provided a hair sample for cortisol analysis before and after the 6-week intervention. Changes in stress from week 1 to week 6 were not observed in the PSS measure; however, cortisol increased significantly in the control group as the term progressed, while it remained relatively stable in the therapy groups, suggesting therapy may lead to greater control of stress. Of participants' demographic characteristics, music sophistication, personality, and changes in quality of life, only the personality trait of conscientiousness correlated significantly with PSS, suggesting online group therapy may be beneficial for a wide range of university students.

Discussion

The results suggest group music therapy can be as effective as group verbal therapy. Further, the study indicates that online delivery can be achieved effectively, supporting the idea that remote therapy may be a viable option for other populations. While the study should be replicated with a larger multi-site sample, it provides one example toward achieving a health-promoting culture on university campuses, consistent with the mental health goals of the Okanagan Charter.
