Effect of recorded male lullaby on physiologic response of neonates in NICU

The Impact of Video Calling Between Preterm Infants and Their Mothers on the Physiological Parameters of Infants and Mother-Infant Bonding

PURPOSE

This study aimed to determine the effect of video calling between preterm infants treated in the neonatal intensive care unit (NICU) and their mothers on the physiological parameters of infants and mother-infant bonding.

BACKGROUND

Preterm infants need prolonged treatment in the NICU, and their families may have difficulty seeing their babies during this treatment process.

METHODS

This is a prospective, randomized-controlled, experimental study. The study sample consisted of 75 preterm infants and their mothers. The data were collected using a maternal introductory information form, a preterm infant introductory information form, a preterm infant physiological parameters follow-up form, and the Mother-Infant Bonding Scale (MIBS). The study included 3 study groups: the video call group, the video call with lullaby group, and the control group. Video calls between preterm infants and their mothers were made through Zoom for 5 to 10 minutes daily for 7 days. The mothers filled out the MIBS online before and on the 7th and 30th days of the study.

RESULTS

Preterm infants in the video call and the video call with lullaby groups had higher MIBS mean scores on the 7th and 30th days of the study than their pretest MIBS scores. Preterm infants in the video call and the video call with lullaby groups had statistically significantly higher MIBS mean scores on the seventh day of the study than those in the control group. At the end of the 7-day study period, there was an improvement in the physiological parameters of preterm infants in the video call group and the video call with lullaby group compared with those in the control group, and this relationship was statistically significant.

CONCLUSIONS

In conclusion, the implementation of video calls between mothers and preterm infants in NICUs had a healing effect on the physiological parameters of preterm infants and increased mother-infant bonding.

Effects of Sound Interventions on the Mental Stress Response in Adults: Protocol for a Scoping Review

BACKGROUND

Sound therapy methods have seen a surge in popularity, with a predominant focus on music among all types of sound stimulation. There is substantial evidence documenting the integrative impact of music therapy on psycho-emotional and physiological outcomes, rendering it beneficial for addressing stress-related conditions such as pain syndromes, depression, and anxiety. Despite these advancements, the therapeutic aspects of sound, as well as the mechanisms underlying its efficacy, remain incompletely understood. Existing research on music as a holistic cultural phenomenon often overlooks crucial aspects of sound therapy mechanisms, particularly those related to speech acoustics or the so-called "music of speech."

OBJECTIVE

This study aims to provide an overview of empirical research on sound interventions to elucidate the mechanism underlying their positive effects. Specifically, we will focus on identifying therapeutic factors and mechanisms of change associated with sound interventions. Our analysis will compare the most prevalent types of sound interventions reported in clinical studies and experiments. Moreover, we will explore the therapeutic effects of sound beyond music, encompassing natural human speech and intermediate forms such as traditional poetry performances.

METHODS

This review adheres to the methodological guidance of the Joanna Briggs Institute and follows the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) checklist for reporting review studies, which is adapted from the Arksey and O'Malley framework. Our search strategy encompasses PubMed, Web of Science, Scopus, and PsycINFO or EBSCOhost, covering literature from 1990 to the present. Among the different study types, randomized controlled trials, clinical trials, laboratory experiments, and field experiments were included.

RESULTS

Data collection began in October 2022. We found a total of 2027 items. Our initial search uncovered an asymmetry in the distribution of studies, with a larger number focused on music therapy compared with those exploring prosody in spoken interventions such as guided meditation or hypnosis. We extracted and selected papers using Rayyan software (Rayyan) and identified 41 eligible papers after title and abstract screening. The completion of the scoping review is anticipated by October 2024, with key steps comprising the analysis of findings by May 2024, drafting and revising the study by July 2024, and submitting the paper for publication in October 2024.

CONCLUSIONS

In the next step, we will conduct a quality evaluation of the papers and then chart and group the therapeutic factors extracted from them. This process aims to unveil conceptual gaps in existing studies. Gray literature sources, such as Google Scholar, ClinicalTrials.gov, nonindexed conferences, and reference list searches of retrieved studies, will be added to our search strategy to increase the number of relevant papers that we cover.

Effect of music-based interventions on physiologic stability of hospitalized preterm infants. A pilot study

BACKGROUND AND OBJECTIVE

Hospitalized preterm infants experience reduced meaningful auditory exposures during a critical period of brain development. Music-based interventions (MBI) may be beneficial, though it remains unclear which stimuli optimally enhance infant stabilization. We investigated the relationship between three conceptually-different MBIs and short-term responses in hospitalized preterm infants.

STUDY DESIGN

This is a case-crossover pilot study including 21 preterm infants between 30 and 35 weeks postmenstrual age. Participants listened to three MBIs and 'no music'; each condition was provided three times in random order. We monitored physiologic and behavioral parameters around each exposure and analyzed results using linear mixed models.

RESULTS

Respiratory rates decreased after each MBI compared with 'no music' (p = 0.02). The most notable decrease occurred following exposure to a low, repetitive musical pattern resembling a lullaby (p = 0.01). We noted no significant changes for the remaining parameters.

CONCLUSION

Specific MBI characteristics may preferentially enhance physiologic stabilization in hospitalized preterm infants.

The Response of the Infant to the Father's Voice: An Evidence-Based Review

BACKGROUND

Premature infants are at increased risk for language delays. The auditory system hears sounds at 25 weeks' gestation; therefore, infants in the neonatal intensive care unit (NICU) may miss crucial language exposure during the period when neural pathways for language processing are developing. Supporting the synergistic relationship between fathers and newborns promotes connections through early language to strengthen engagement and promote infant neurodevelopment.

PURPOSE

To determine what is known about preterm infants' response to the male voice.

DATA SOURCES

Three databases and forward searching of reference lists were used to locate articles addressing the clinical question: "What strategies can be used in the NICU to support purposeful language development?"

STUDY SELECTION

Empiric, primary research studies were included if they were published in English without date restriction.

DATA EXTRACTION

The authors evaluated each study's quality using a validated 16-item assessment tool (QATSDD) developed for studies with diverse designs; data were extracted and organized following Garrard's Matrix Method.

RESULTS

The aim of this evidence-based review is to report the way an infant responds to the paternal voice. Findings promote a better understanding of individual infant response to paternal voice, including conversational turns and engagement behaviors. Although informative, this review highlights a clear gap in the evidence, supporting standardized methodology.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Fathers should be encouraged to communicate vocally early and often to facilitate bonding in the NICU. Encouraged future study of father-infant communication to support bonding, relationship building, and neurodevelopmental outcomes is paramount.

Use of Musical Intervention in the Pediatric Intensive Care Unit of a Developing Country: A Pilot Pre–Post Study

Music is frequently used in different clinical settings, and it is implemented as a complementary, low-cost and useful intervention to reduce pain, anxiety and to improve relaxation. This pilot pre–post study aimed to examine the feasibility and preliminary effectiveness of a specific musical intervention in patients ≤16 years admitted to the Pediatric Intensive Care Unit (PICU) of an Iraqi hospital. The COMFORT Behavior Scale (CBS) was used by nurses to assess the level of sedation. Fifty-nine children were enrolled during the study period (March 2020–August 2021). CBS was lowered by 2.2 (95% CI: 1.9 to 2.6) points after 30 min, and by 3.3 (95% CI: 2.9 to 3.6) points after 60 min from music initiation. Thirty minutes after music initiation, heart rate decreased by 6.3 (95% CI: 4.5 to 8.1) beats per minute, whereas at 60 min, heart rate decreased by 9.1 (95% CI: 7.2 to 10.9) beats per minute. No clinically significant variations were detected in the other vital signs (blood pressure, respiratory rate and oxygen saturation). These findings support the feasibility of musical intervention in a developing country. CBS and heart rate variation may be worth following up in larger and conclusive studies.

Utilising recorded music to reduce stress and enhance infant neurodevelopment in neonatal intensive care units

AIM

This paper summarises published evidence on the use of recorded music in high-risk infants to reduce stress and improve neurodevelopment, forming recommendations for proposed clinical applications in neonatal intensive care units.

METHODS

We searched two comprehensive library catalogues and two databases for articles evaluating the impact of recorded music interventions on hospitalised preterm infants. Original and review papers published in English in the 10 years prior to this search were selected if the study included a component of recorded music interventions.

RESULTS

Most original studies (80.95%) and all literature reviews (100%) reported positive effects of recorded music interventions for preterm infants, primarily in the short term. No negative effects were reported. Evidence is emerging regarding the neurobiological mechanisms of recorded music on longer-term effects on preterm infant neurodevelopment. Clinical applications were suggested drawing upon available evidence. Due to generally small sample sizes and variability in study design, unanswered questions remain.

CONCLUSION

Carefully designed recorded music interventions appear to be safe, feasible and effective in reducing stress and improving neurodevelopment of hospitalised infants. Additional rigorous, well-powered trials with relevant outcomes are needed to further refine specific elements for recorded music interventions to better inform practice.

Comparing the effectiveness of mother's live lullaby and recorded lullaby on physiological responses and sleep of preterm infants: a clinical trial study

OBJECTIVES

Environmental stimuli in neonatal intensive care units can disrupt the physiological stability and sleep of infants. It is essential to perform nursing interventions to reduce the adverse effects of such stimuli. This study aimed to compare the effect of recorded lullabies and mothers' live lullabies on physiological responses and sleep duration of preterm infants.

METHODS

This study was a randomized clinical trial. The participants were 90 preterm infants selected using convenience sampling. In the intervention groups, music (recorded lullabies and mother's live lullabies) was played for 14 days, 20 min a day, while the control group did not receive any intervention. The data were collected using physiological criteria and infant sleep checklists before, during, and after the intervention. The data were analyzed using SPSS software (Version 21.0).

RESULTS

The mean scores of physiological parameters (O2 saturation and heart rate) were not significantly different in the three groups before, during, and after the intervention (p>0.05). However, there was an improvement in O2-saturation and a decrease in the heart rate in two intervention groups. The mean duration of the infants' overnight sleep was not statistically significant between the groups before the intervention (p>0.05). However, there was a statistically significant difference in the intervention groups after the intervention, (p<0.05), and the infants' overnight sleep was longer in the recorded-lullaby group than the other two groups.

CONCLUSIONS

Although performing interventions, including recorded lullaby and mother's live lullaby did not differ significantly with that of the control group in physiological criteria, it can be clinically important. In addition, recorded-lullaby increased the infants' overnight sleeping. Thus, it is suggested that further studies be conducted to confirm the effect of recorded lullaby and mother's live lullaby interventions on physiological parameters and sleep duration of hospitalized infants.

Evaluating physiologic outcomes of music interventions in the neonatal intensive care unit: a systematic review

Music is widely used in the neonatal intensive care unit. The objectives of this systematic review are: (1) clarify the current literature in regards to the impact of music on neonatal physiologic parameters, (2) highlight the variability in definitions utilized for music interventions, and (3) provide a foundation for future music therapy research focused on influencing neonatal physiology. A systematic literature review was conducted in accordance with PRISMA guidelines, with search terms including "music," "music therapy," "neonates," "newborn," and "NICU." Four hundred and fifty-eight studies were reduced to 16 clinical trials divided based on methodological description of music intervention. Our review highlights variability in the existing literature specifically on neonatal physiological impact of music. Future studies should focus on consistent and well-defined data collection, utilization of standardized definitions for music interventions, and consideration of more sensitive markers of physiology, such as heart rate variability, to enhance study rigor and reproducibility.

Effect of music therapy on preterm infants in neonatal intensive care unit: Systematic review and meta-analysis of randomized controlled trials

AIM

To systematically examine the effectiveness of music therapy on preterm infants in neonatal intensive care unit.

BACKGROUND

In recent years, the application of music therapy for preterm infants in neonatal intensive care unit has attracted more and more attention because of its clinical effects. However, there still exist disputes among different studies.

DESIGN

A systematic review and meta-analysis.

DATA SOURCES

Eleven databases were searched over the period from 1910 -4 November 2019.

REVIEW METHODS

Papers were selected for analysis in accordance with the PRISMA guidelines. The meta-analysis was carried out by using Review Manager 5.3 software.

RESULTS

A total of 13 trials involving 1,093 participants were included. Meta-analysis showed music therapy had a significant influence on preterm infant's heart rate, respiratory rate, oral feeding volume, stress level, and maternal anxiety with moderate-to-high heterogeneity among studies. Also, music therapy had no influences on oxygen saturation and behavioural state.

CONCLUSIONS

Music therapy can not only effectively improve preterm infant's heart rate, stable respiratory rate, and attenuate stress level but also exert positive impact on oral feeding volume. In addition, music therapy also plays a role in reducing maternal anxiety. However, due to the heterogeneity across studies in some outcomes, further studies with larger sample size and more stringent design should be conducted before recommendation.

IMPACT

Music therapy can significantly improve preterm infant's heart rate, respiratory rate, and stress level, as well as increase oral feeding volume. These results may exert a positive impact on well-being and quality of life in preterm infants in the neonatal intensive care unit. Hospitals can apply music therapy which has been considered a non-pharmacological and no-invasive treatment to preterm infants in the neonatal intensive care unit.

Evaluating the Effect of Family-Centered Intervention Program on Care Burden and Self-Efficacy of Hemodialysis Patient Caregivers Based on Social Cognitive Theory: A Randomized Clinical Trial Study

BACKGROUND

Caregivers of hemodialysis patients spend a large amount of time providing care to these patients while tolerating fatigue and stress. This study evaluated a family-centered empowerment program on the care burden and self-efficacy of hemodialysis patient caregivers based on social cognitive theory.

METHODS

In this randomized clinical trial, 70 family caregivers of hemodialysis patients in Isfahan, Iran, were selected and randomly allocated to intervention and control groups, in 2015-2016. Two questionnaires were used to collect the family caregivers' characteristics, care burden, and self-efficacy, and patients' negative and positive outcomes expectancies. Data were analyzed using SPSS before, immediately after, and 2 months after the intervention.

RESULTS

There was no significant difference in the mean scores of care burden, positive outcomes expectancies, negative outcomes expectancies, and self-efficacy between the two groups before the intervention. However, there were significant differences in the post-test and follow-up data analyses (P<0.05).

CONCLUSION

Given the degenerative nature of chronic kidney disease, it can be considered as a source of long-term and chronic stress for caregivers. Therefore, by implementing an empowerment program, caregiving behaviors can be improved, positive outcomes expectancies can be increased, and negative outcomes expectancies can be reduced.

Interactive sequences between fathers and preterm infants in the neonatal intensive care unit

AIMS

The first purpose of the study was to examine fathers' spontaneous communicative behavior with their preterm infants in the neonatal intensive care unit, and how father's and infant's behaviors affected each other. The second purpose was to examine any possible association between the fathers' and/or infants' characteristics and the quality of fathers' behaviors with their infants.

STUDY DESIGN/SUBJECTS/OUTCOME MEASURES

Father-preterm infant dyads (n=20) were assessed at 34-36 weeks postmenstrual age, during a spontaneous face-to-face communication with the infant placed in a heated cot in the NICU, and coded according to the Parent-Preterm Infant Coding System.

RESULTS

The presence of the father's Affiliative Behavior increased the occurrences of infant Gazing at the parent's face. In turn, infant gazing increased the occurrence of paternal Affiliative Behavior. The likelihood of infant's Gazing at the father's face was also significantly elicited by infrequent occurrences of paternal Affectionate Talk, co-occurring with Gazing at infant with Positive Facial Affect (but no Touch). With regard to the predictors of quality in father-infant interactions, we found a significant positive correlation between fathers' level of depressive symptomatology and fathers' Affiliative Behavior.

CONCLUSION

Our results show the of bidirectional sequential patterns of communication between fathers and preterm infants at 35 weeks postmenstrual age, and provide important information about the quality and modalities of paternal communication and their influence on infant behavioral states. From a clinical perspective, these results suggest that father-specific interventions designed to improve and sustain fathers' positive engagement with infants in the NICU should be pursued.

Parenting apps review: in search of good quality apps

BACKGROUND

Parenting can be challenging, and in this digital age, first-time parents actively access mobile applications or "apps" to adjust to their new roles. Apps are now technologically-savvy parents' go-to tool for accessing information, tracking their babies' development, editing and sharing photos, and much more. While apps have the potential to make parenting easier, the abundance of low-quality apps makes the process of finding a reliable one arduous for parents. Therefore, the objective of this app review paper was to provide a list of quality parenting apps that parents can use.

METHODS

The Google Play Store was searched on June 1st, 2018 for available parenting apps using 18 search terms: mum, mom, mommy, mama, mother, father, dad, daddy, papa, newborn, baby, infant, kid, child, children, family, parent, and parenting. The eligible apps (n=16) were evaluated on engagement, functionality, aesthetics, and information domains using Mobile App Rating Scale (MARS).

RESULTS

The authors identified 4,300 free apps on the initial search, of which n=16 apps were included in the review. All 16 apps were freely available to the public on Google Play Store. Most apps (n=13) were also available on the iOS platform. All eligible apps had a privacy policy, and half of the apps contained advertisements. Most apps (n=12) were updated within the last year and received 4.5 or above ratings from users. Babybrains app, developed by a neuroscientist, had the lowest number of downloads (one thousand) whereas, BabyCenter, a commercial app, had the highest number of downloads (ten million). A majority of apps (n=11) received MARS scores between 4.2 and 4.4/5, with four apps received highest MARS score of 4.5/5, and one app received the lowest MARS rating of 4/5.

CONCLUSIONS

Apps play an increasingly important role in supporting new parents in their first year of parenthood due to convenience and ease of accessibility. Health care professionals are in an ideal position to support technologically savvy parents in locating good quality apps; therefore, they should support the evaluation of existing parenting apps to ensure that the parents are presented with the up to date and best options.

Effects of Listening to Live Singing in Patients Undergoing Hemodialysis: A Randomized Controlled Crossover Study

Background:

Participation in music therapy is associated with improved psychological and physical indices among chronically ill patients. Listening to music during hemodialysis treatments positively affects patients’ hemodynamics, laboratory values, quality of life, and physical symptoms. The effect of live singing during hemodialysis treatments, however, has not previously been studied.

Methods:

A total of 24 participants with a diagnosis of end-stage kidney disease participated in the study. The vocalist was a musically trained dialysis nurse. Twelve of the patients listened to 15 min of live singing during 6 consecutive hemodialysis sessions, while the other 12 underwent standard hemodialysis. After a washout period of 2 days, the two groups were reversed.

Results:

Listening to live music was associated with improvements in systolic and diastolic blood pressure, better quality of sleep, fewer cramps, and reduced anxiety/depression, pain, and itching ( p < .05, all values).

Conclusions:

Listening to live music during hemodialysis is an effective and potentially low-cost therapy for the dialysis care team to employ during hemodialysis treatments.

Music reduces pain perception in healthy newborns: A comparison between different music tracks and recoded heartbeat

OBJECTIVES

To assess the effect of 3 musical interventions, as compared to no music, on the physiological response of healthy newborns undergoing painful medical procedures (Guthrie test and/or intramuscular antibiotic injections).

METHODS

Prospective study of 80 full-term newborns, aged 1 to 3 days, randomly allocated to exposure to Mozart's Sonata for two pianos K.448, Beethoven's Moonlight Sonata, heartbeat sound recordings (70 bpm) or no music. Pain perception (evaluated using the Neonatal Infant Pain Scale), heart rate and oxygen saturation were measured 10 min before (T0), during (T1), 10 (T2) and 20 (T3) minutes after the interventions.

RESULTS

Infants who were exposed to the three music interventions displayed a significant reduction in heart rate and in pain perception and an increase in oxygen saturation, as compared to the control group, which showed less modifications on stress measurements after painful medical procedures (F_(3,76) = 6.40, p = .001, partial η² = 0.20).

CONCLUSIONS

Exposure to music and heartbeat sound recordings changes short-term physiological parameters in healthy newborns undergoing potentially painful procedures. The similar effect shown by the 3 interventions might be explained by the common characteristics of the sound shared by the various tracks. Further research is needed to investigate the impact of different types of music used in intervention, in order to develop guidelines and include music as a part of evidence-based strategies to promote the outcome for neonates.
