The effect of audio therapy to treat postoperative pain in children undergoing major surgery: a randomized controlled trial

Virtual reality reduces anxiety of children in the plaster room: a randomized controlled trial

Aims

Paediatric fractures are highly prevalent and are most often treated with plaster. The application and removal of plaster is often an anxiety-inducing experience for children. Decreasing the anxiety level may improve the patients' satisfaction and the quality of healthcare. Virtual reality (VR) has proven to effectively distract children and reduce their anxiety in other clinical settings, and it seems to have a similar effect during plaster treatment. This study aims to further investigate the effect of VR on the anxiety level of children with fractures who undergo plaster removal or replacement in the plaster room.

Methods

A randomized controlled trial was conducted. A total of 255 patients were included, aged five to 17 years, who needed plaster treatment for a fracture of the upper or lower limb. Randomization was stratified for age (five to 11 and 12 to 17 years). The intervention group was distracted with VR goggles and headphones during the plaster treatment, whereas the control group received standard care. As the primary outcome, the post-procedural level of anxiety was measured with the Child Fear Scale (CFS). Secondary outcomes included the children's anxiety reduction (difference between CFS after and CFS before plaster procedure), numerical rating scale (NRS) pain, NRS satisfaction of the children and accompanying parents/guardians, and the children's heart rates during the procedure. An independent-samples t-test and Mann-Whitney U test (depending on the data distribution) were used to analyze the data.

Results

The post-procedural CFS was significantly lower (p < 0.001) in the intervention group (proportion of children with no anxiety = 78.6%) than in the control group (56.8%). The anxiety reduction, NRS pain and satisfaction scores, and heart rates showed no significant differences between the control group and the intervention group. Subanalyses showed an increased effect of VR on anxiety levels in young patients, females, upper limb fractures, and those who had had previous plaster treatment.

Conclusion

VR effectively reduces the anxiety levels of children in the plaster room, especially in young girls. No statistically significant effects were seen regarding pain, heart rate, or satisfaction scores.

The effect of listening to music and foot reflexology on nausea, pain and anxiety in children during perioperative period: A randomized controlled study

AIM

The purpose of this research was to examine the effects of listening to music and foot reflexology during the perioperative period on nausea, pain and anxiety in children aged 7-12 years.

MATERIAL AND METHOD

The sample for the randomized controlled experimental study included children who underwent outpatient surgery in the Pediatric Surgery Clinic. Research data were collected. A total of 99 children were included in the study with 33 in the music group, 33 in the foot reflexology group, and 33 in the control group.

RESULTS

In the preoperative and postoperative periods, Children's Perioperative Multidimensional Anxiety Scale (CPMAS) scores for the music listening and reflexology groups were significantly lower than the control group (p < 0.05). In the postoperative period, the Children's Emotional Manifestation Scale (CEMS) scores for the reflexology and music listening groups after the application were significantly lower than the control group (p < 0.001). Postoperative Baxter Retching Faces (BARF) scores were found to be significantly lower in children who listened to music compared to the control group (p = 0.002). The Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) scores for children in the control group were found to be significantly higher in the postoperative period than for children in the music and reflexology groups (p < 0.001).

CONCLUSIONS

As a result, listening to music and reflexology during the perioperative period were effective in reducing anxiety, pain and nausea in children.

PRACTICE IMPLICATIONS

In the perioperative period, listening to music and reflexology for children can be recommended as non-pharmacological nursing interventions with low cost and easy implementation.

Effect of virtual reality combined with repetitive transcranial magnetic stimulation on musculoskeletal pain and motor development in children with spastic cerebral palsy: a protocol for a randomized controlled clinical trial

PURPOSE

This trial aims to investigate the efficacy and safety of virtual reality (VR) combined with repetitive transcranial magnetic stimulation (rTMS) for improving musculoskeletal pain and motor development in children with unilateral spastic cerebral palsy (CP).

METHODS

This study protocol is for a randomized controlled trial consisting of 2 treatment sessions (3 days/week for 4 weeks in each session, with a 1-week interval between sessions). We will recruit children aged 3-10 years with unilateral spastic CP (Gross Motor Function Classification System level I or II). Participants will be randomly divided into 3 groups: the VR + rTMS group (immersive VR intervention, rTMS and routine rehabilitation therapy), rTMS group (rTMS and routine rehabilitation therapy), and control group (sham rTMS and routine rehabilitation therapy). VR therapy will involve a daily 40-minute movement training session in a fully immersive environment. rTMS will be applied at 1 Hz over the primary motor cortex for 20 min on the contralateral side. The stimulation intensity will be set at 90% of the resting motor threshold, with 1200 pulses applied. A daily 60-minute routine rehabilitation therapy session including motor training and training in activities of daily living will be administered to all participants. The primary outcome will be pain intensity, assessed by the Revised Face, Legs, Activity, Cry, and Consolability Scale (R-FLACC). The secondary outcomes will include motor development, evaluated by the 66-item version of the Gross Motor Function Measure (GMFM-66) and Fine Motor Function Measure (FMFM); balance capacity, measured by the interactive balance system; activities of daily living; and quality of life, measured by the Barthel index and the Chinese version of the Cerebral Palsy Quality of Life scale for Children (C-CP QOL-Child). Safety will be monitored, and adverse events will be recorded during and after treatment.

DISCUSSION

Combined application of VR therapy and rTMS may reveal additive effects on pain management and motor development in children with spastic CP, but further high-quality research is needed. The results of this trial may indicate whether VR therapy combined with rTMS achieves a better analgesic effect and improves the motor development of children with spastic CP.

Non-pharmacological management of infant and young child procedural pain

BACKGROUND

Despite evidence of the long-term implications of unrelieved pain during infancy, it is evident that infant pain is still under-managed and unmanaged. Inadequately managed pain in infancy, a period of exponential development, can have implications across the lifespan. Therefore, a comprehensive and systematic review of pain management strategies is integral to appropriate infant pain management. This is an update of a previously published review update in the Cochrane Database of Systematic Reviews (2015, Issue 12) of the same title.

OBJECTIVES

To assess the efficacy and adverse events of non-pharmacological interventions for infant and child (aged up to three years) acute pain, excluding kangaroo care, sucrose, breastfeeding/breast milk, and music.

SEARCH METHODS

For this update, we searched CENTRAL, MEDLINE-Ovid platform, EMBASE-OVID platform, PsycINFO-OVID platform, CINAHL-EBSCO platform and trial registration websites (ClinicalTrials.gov; International Clinical Trials Registry Platform) (March 2015 to October 2020). An update search was completed in July 2022, but studies identified at this point were added to 'Awaiting classification' for a future update.  We also searched reference lists and contacted researchers via electronic list-serves.  We incorporated 76 new studies into the review.  SELECTION CRITERIA: Participants included infants from birth to three years in randomised controlled trials (RCTs) or cross-over RCTs that had a no-treatment control comparison. Studies were eligible for inclusion in the analysis if they compared a non-pharmacological pain management strategy to a no-treatment control group (15 different strategies). In addition, we also analysed studies when the unique effect of adding a non-pharmacological pain management strategy onto another pain management strategy could be assessed (i.e. additive effects on a sweet solution, non-nutritive sucking, or swaddling) (three strategies). The eligible control groups for these additive studies were sweet solution only, non-nutritive sucking only, or swaddling only, respectively. Finally, we qualitatively described six interventions that met the eligibility criteria for inclusion in the review, but not in the analysis.  DATA COLLECTION AND ANALYSIS: The outcomes assessed in the review were pain response (reactivity and regulation) and adverse events. The level of certainty in the evidence and risk of bias were based on the Cochrane risk of bias tool and the GRADE approach. We analysed the standardised mean difference (SMD) using the generic inverse variance method to determine effect sizes.  MAIN RESULTS: We included total of 138 studies (11,058 participants), which includes an additional 76 new studies for this update. Of these 138 studies, we analysed 115 (9048 participants) and described 23 (2010 participants) qualitatively. We described qualitatively studies that could not be meta-analysed due to being the only studies in their category or statistical reporting issues. We report the results of the 138 included studies here. An SMD effect size of 0.2 represents a small effect, 0.5 a moderate effect, and 0.8 a large effect. The thresholds for the I2 interpretation were established as follows: not important (0% to 40%); moderate heterogeneity (30% to 60%); substantial heterogeneity (50% to 90%); considerable heterogeneity (75% to 100%). The most commonly studied acute procedures were heel sticks (63 studies) and needlestick procedures for the purposes of vaccines/vitamins (35 studies). We judged most studies to have high risk of bias (103 out of 138), with the most common methodological concerns relating to blinding of personnel and outcome assessors. Pain responses were examined during two separate pain phases: pain reactivity (within the first 30 seconds after the acutely painful stimulus) and immediate pain regulation (after the first 30 seconds following the acutely painful stimulus). We report below the strategies with the strongest evidence base for each age group. In preterm born neonates, non-nutritive sucking may reduce pain reactivity (SMD -0.57, 95% confidence interval (CI) -1.03 to -0.11, moderate effect; I2 = 93%, considerable heterogeneity) and improve immediate pain regulation (SMD -0.61, 95% CI -0.95 to -0.27, moderate effect; I2 = 81%, considerable heterogeneity), based on very low-certainty evidence. Facilitated tucking may also reduce pain reactivity (SMD -1.01, 95% CI -1.44 to -0.58, large effect; I2 = 93%, considerable heterogeneity) and improve immediate pain regulation (SMD -0.59, 95% CI -0.92 to -0.26, moderate effect; I2 = 87%, considerable heterogeneity); however, this is also based on very low-certainty evidence. While swaddling likely does not reduce pain reactivity in preterm neonates (SMD -0.60, 95% CI -1.23 to 0.04, no effect; I2 = 91%, considerable heterogeneity), it has been shown to possibly improve immediate pain regulation (SMD -1.21, 95% CI -2.05 to -0.38, large effect; I2 = 89%, considerable heterogeneity), based on very low-certainty evidence. In full-term born neonates, non-nutritive sucking may reduce pain reactivity (SMD -1.13, 95% CI -1.57 to -0.68, large effect; I2 = 82%, considerable heterogeneity) and improve immediate pain regulation (SMD -1.49, 95% CI -2.20 to -0.78, large effect; I2 = 92%, considerable heterogeneity), based on very low-certainty evidence.  In full-term born older infants, structured parent involvement was the intervention most studied. Results showed that this intervention has little to no effect in reducing pain reactivity (SMD -0.18, 95% CI -0.40 to 0.03, no effect; I2 = 46%, moderate heterogeneity) or improving immediate pain regulation (SMD -0.09, 95% CI -0.40 to 0.21, no effect; I2 = 74%, substantial heterogeneity), based on low- to moderate-certainty evidence. Of these five interventions most studied, only two studies observed adverse events, specifically vomiting (one preterm neonate) and desaturation (one full-term neonate hospitalised in the NICU) following the non-nutritive sucking intervention. The presence of considerable heterogeneity limited our confidence in the findings for certain analyses, as did the preponderance of evidence of very low to low certainty based on GRADE judgements.

AUTHORS' CONCLUSIONS

Overall, non-nutritive sucking, facilitated tucking, and swaddling may reduce pain behaviours in preterm born neonates. Non-nutritive sucking may also reduce pain behaviours in full-term neonates. No interventions based on a substantial body of evidence showed promise in reducing pain behaviours in older infants. Most analyses were based on very low- or low-certainty grades of evidence and none were based on high-certainty evidence. Therefore, the lack of confidence in the evidence would require further research before we could draw a definitive conclusion.

Impact of music therapy and hand massage in the pediatric intensive care unit on pain, fear and stress: Randomized controlled trial

PURPOSE

This study was performed with the aim of assessing the effect of music therapy and hand massage on pain, fear and stress among 12-18 year-old adolescents treated in the pediatric intensive care unit (PICU).

DESIGN

This study was a randomized controlled trial, with single-blind design.

METHODS

The adolescents were divided into groups with 33 receiving hand massage, 33 receiving music therapy and 33 in the control group. Collection of data used the Wong-Baker FACES (WB-FACES) Pain Rating Scale, Children's Fear Scale (CFS) and blood cortisol levels.

FINDINGS

In the study, adolescents in the music therapy group had lower mean points for WB-FACES before, during and after the procedure by a significant level compared to the control group (p < 0.05). Additionally, the CFS mean points before and during the procedure were lowest in the music therapy group, while the music therapy and massage groups were determined to have lower points by a significant level after the procedure compared to the control group (p < 0.05). However, when the mean cortisol levels of adolescents before the procedure and on the 1st and 2nd day after the procedure were compared, there was no significant difference between the groups (p > 0.05).

CONCLUSIONS

It was determined that hand massage and music therapy were more effective than standard care at reducing pain and fear levels during blood drawing among 12-18-year-old adolescents in the PICU.

PRACTICE IMPLICATIONS

Nurses may use music therapy and hand massage to manage fear and pain related to blood drawing in the PICU.

Effectiveness of stress ball and relaxation exercises on polymerase chain reaction (RRT-PCR) test-induced fear and pain in adolescents in Türkiye

PURPOSE

This study aimed to determine the effectiveness of stress balls and relaxation exercises in relieving PCR test-induced fear and pain in adolescents.

DESIGN AND METHODS

A randomized controlled experimental study with a parallel-group design was conducted. The sample size was determined by G*Power analysis, and 32 adolescents were included in each group accordingly. The data were collected using the Adolescent and Parent Information Form, The Children's Fear Scale, and The Wong-Baker Faces Pain Scale. Descriptive statistics, t-test, paired t-test, ANOVA, and Tukey's forward analysis were used to analyze the data.

RESULTS

The mean age was 14.93 ± 2.07 years for the adolescents, 43.58 ± 4.50 years for the mothers, and 48.25 ± 4.92 years for the fathers. Adolescents were stratified according to age, gender, and fear of invasive procedures, and homogeneity was ensured in their distribution to the groups. The pre-procedural level of fear was moderate in each group with no significant difference (p > 0.05). However, a significant difference was found between the groups in terms of both post-procedure levels of fear and pain. The pre-procedural fear of the adolescents in the control group (3.91 ± 0.29) did not change much after the procedure (3.91 ± 0.30), while there was a decrease in the other groups. The least post-procedure fear (0.09 ± 0.29) and pain (0.44 ± 0.67) were found to be in the relaxation exercise group.

CONCLUSIONS AND PRACTICE IMPLICATIONS

Relaxation exercise is the most effective method to reduce fear and pain during the PCR procedure. It is recommended to use it during the PCR procedure for being easily accessible, applicable, and cost-effective. Clinical Trials ID: NCT05250544.

The Role of Music-Based Interventions in Orthopaedic Surgery

Music-based interventions (MBIs), such as music therapy, are interventions in which music is used to address the physical, emotional, and social needs of individuals. The origin of music-based therapy can be traced to ancient Egypt and expanded into the United States during the mid-1900s. These interventions have shown efficacy in reducing anxiety and pain in both nonsurgical and surgical settings across various medical specialities, one of which is orthopaedic surgery. Prior studies have investigated the use of MBI in adult and paediatric patients and have shown an improvement in patient well-being following medical care and a reduction in healthcare costs across both patient populations. This standard review covers the current utility of MBI in the field of orthopaedic surgery and explores the current literature on the application and limitations of MBI in both the operative and nonoperative aspects of orthopaedic care.

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.

Effect of slow tempo music on markers of anxiety during cataract surgery: Randomized control trial

PURPOSE:

This study aims to objectively measure the effect of slow tempo music on various markers for anxiety.

MATERIALS AND METHODS:

This is a repeated measure randomized control trial of patients with age-related cataracts undergoing cataract extraction through phacoemulsification under local anesthesia. Patients were randomized into two groups: music group where a standardized piano music was played and control group. Salivary alpha-amylase (sAA) levels were measured at the beginning and at the end of surgery. Blood pressure and heart rate were also measured at 5 min before surgery and at four other standardized points during and after surgery. Visual Analog Scale for anxiety was also gauged: preoperatively, perioperatively, and 15 min postoperatively.

RESULTS:

Ninety-two patients were randomized equally to the music group and control group. Paired sample t-test showed a reduction in the level of sAA during surgery in the music group (P = 0.019). The odds ratio for a drop in sAA with music was 4.407 (P = 0.001). Lower systolic blood pressure was observed in the music group: at delivery of local anesthesia (P = 0.047), at first incision (P = 0.023), and during sculpting (P = 0.15). Similarly, diastolic blood pressure was lower at first incision (P = 0.019) in the music group. The visual analog scale for anxiety during surgery was found to be lower in the music group (P = 0.046).

CONCLUSION:

A slow tempo music during cataract surgery was shown to significantly reduce several indicators for anxiety at various points during cataract surgery.

Using Vibrating and Cold Device for Pain Relieves in Children: A Systematic Review and Meta-analysis of Randomized Controlled Trials

OBJECTIVE

Needle procedures are the most common source of pain, anxiety, and fear among children. A combination of a cooling ice-pack and/or a vibrating motor for pain management in children has been evaluated in trials, but their overall effects await a synthesis of the available evidence.

METHOD

Comprehensive search was conducted using Cochrane, PubMed, EMBASE, PsycINFO, CINAHL and Airiti. We calculated pooled risk ratios (RR), mean difference (MD) and 95% CI using RevMan 5.3. A meta-regression was conducted to investigate the effects of mean age on MD of pain.

RESULTS

A total of 1479 children from 16 publications were included. Compared with the control group, using cold-vibrating device significantly decreased pain level above the age of 2 (MD -3.03, 95% CI: -3.38, -2.68), as well as lower anxiety level among parents (MD -1.3, 95% CI: -1.9, -0.7). Meta-regression demonstrated a significant negative correlation of pain score with age. For children at 8.5 years, cold-vibration reduced the pain score by 0.13 averagely for every increment in year compared with controls (MD -0.13; 95% CI: -0.25, -0.01). No adverse events were reported in included studies.

DISCUSSION

The cold-vibrating device reduced pain levels significantly among children without adverse effects. Variation of factors might contribute to the heterogeneity of our study, such as age, different needle procedures, psychological strategies…etc.

CONCLUSIONS

Cool-vibration treatment reduced pain levels in children who underwent needle procedures and the treatment appears more effective in older children. The device is promising in clinical setting due to its non-invasiveness and ease of usage.

Examining the Effects of Music-Based Interventions on Pain and Anxiety in Hospitalized Children: An Integrative Review

PROBLEM

Children often experience pain and anxiety during a hospital stay. Effective pain and anxiety management plays a crucial role in healing. However, recent literature has highlighted multiple barriers to managing pain and anxiety in children, such as parent and provider fears of the adverse effects of pain and anxiety medications.

ELIGIBILITY CRITERIA

A database search was conducted for articles published between 2009 and 2019 to evaluate the impact of nurse-led, music-based interventions as an adjunct method of pain and anxiety management in hospitalized children. Articles were included if study subjects were ages 0-21 years old, the study used live or recorded music as an intervention, and occurred in an inpatient setting.

SAMPLE

A total of seven randomized control trials and one quasi-experimental study were included for analysis.

RESULTS

There is consistent and significant evidence that music can reduce anxiety in hospitalized children before and during procedures. Results with respect to pain and vital signs, often viewed as the physiologic analogs to pain, were mixed.

CONCLUSIONS

Music-based interventions are safe for hospitalized children. Several studies highlighted the importance of patient preference in selecting music for children. A heavy reliance on pre-recorded audio, delivered via headphones illustrates the feasibility and cost-effectiveness of music-based interventions.

IMPLICATIONS

Nurse-led, music-based interventions have been shown to be an affordable, safe, effective, and feasible alternative for managing anxiety in hospitalized children. Music should be considered as an adjunct therapy to traditional anxiety treatment. Further research is needed to determine the effects of music on pain.

Application and effects of an early childhood education machine on analgesia and sedation in children after cardiothoracic surgery

OBJECTIVE

To study the effect of an early childhood education machine on sedation and analgesia in children after cardiothoracic surgery.

METHODS

A prospective randomized controlled study was conducted in a provincial hospital in China. Fifty-two patients (aged from 1 to 5 years) underwent cardiothoracic surgery (including: ventricular septal defect, patent ductus arteriosus, atrial septal defect, pulmonary stenosis, pulmonary sequestration and congenital cystic adenomatoid lung malformation) were divided into the study group (n = 26) and the control group (n = 26). The patients in the study group underwent intervention with an early childhood education machine (uniform type) in addition to routine standard treatment and nursing, while the patients in the control group only received routine standard treatment and nursing. Richmond agitation sedation score (RASS) and face, legs, activity, cry, consolability (FLACC) score of all of the patients were evaluated, and the negative emotions (self-rating anxiety scale (SAS) score and self-rating depression scale (SDS) score) of the parents of the two groups were compared.

RESULTS

There was no significant difference in the general clinical data between the two groups. The RASS and FLACC scores in the study group were significantly lower than those in the control group, and the SAS and SDS scores of the parents in the study group were significantly lower than those in the control group.

CONCLUSION

The application of an early childhood education machine for children after cardiothoracic surgery can effectively reduce postoperative agitation, improve sedation and analgesia of the patients, and ease the pessimistic mood of the patients' parents.

The music video therapy in postoperative analgesia in preschool children after cardiothoracic surgery

OBJECTIVES

To observe the effect of music video (MV) therapy on early postoperative pain in preschool children after cardiothoracic surgery.

METHODS

116 preschool children undergoing cardiothoracic surgery were randomly divided into the MV and control groups from June 2019 to March 2020. The related vital signs parameters, the Wong-Baker FACES pain rating scale, the FLACC scale, the number of postoperative PCA press and the cumulants of sufentanil use were recorded and analyzed.

RESULTS

There were no statistically significant differences in general characteristics and preintervention data between the two groups. However, there were significantly lower in the heart rate, mean arterial pressure, respiratory rate, the number of postoperative PCA press, and the dosage of sufentanil in the MV group than those in the control group after the intervention. The Wong-Baker FACES and FLACC scales in the MV group were significantly lower than those in the control group at the time point of immediately after the first intervention, 1 day, and 2 days after the intervention. The two pain scores showed a downward trend over time, and the corresponding scores in the MV group were better than those in the control group.

CONCLUSION

MV therapy can be an effective nonpharmaceutical intervention in the clinical to relieve children's postoperative pain after cardiothoracic surgery.

The Effect of Different Audio Distraction Methods on Children's Postoperative Pain and Anxiety

PURPOSE

The aim of the study was to determine the effect of different auditory methods of attention distraction on postoperative pain and anxiety in children.

DESIGN

The study was conducted as a pretest-posttest experimental study to determine the effect of classical music, Turkish music, and audiobook on the reduction of postoperative pain and anxiety in children.

METHODS

The patient population of the study comprised children who had undergone a surgical operation in the pediatric surgery clinics. A total of 90 children were included in the sample of the study. The data were collected using the Visual Analog Scale, the Wong-Baker Faces Pain Scale, and the State-Trait Anxiety Inventory for children, in addition to the sociodemographic data form of the child and the parent.

FINDINGS

Classical music, Turkish music, and audiobook methods played an effective role in decreasing postoperative pain and the anxiety state in children. Classical music listening was the most effective method in reducing the pain in children in the postoperative period in the three groups in the study.

CONCLUSIONS

We demonstrated that different auditory attention distraction methods had a decreasing effect on postoperative pain and anxiety in children.

Postoperative Pain Management in Pediatric Patients Undergoing Cardiac Surgery: Where Are We Heading?

OBJECTIVES

Adequate postoperative pain management is crucial in pediatric patients undergoing cardiac surgery because pain can lead to devastating short- and long-term consequences. This review discusses the limitations of current postoperative pain assessment and management in children after cardiac surgery, the obstacles to providing optimal treatment, and concepts to consider that may overcome these barriers.

DATA SOURCE

MEDLINE and PubMed.

CONCLUSIONS

Effective pain management in infants and young children undergoing cardiac surgery continues to evolve with innovative methods of both assessment and therapy using newer drugs or novel routes of administration. Artificial intelligence- and machine learning-based pain assessment and patient-tailored management in both pain measurement and prevention are already being integrated into the routine of current practice.

Psychological interventions for needle-related procedural pain and distress in children and adolescents

BACKGROUND

This is the second update of a Cochrane Review (Issue 4, 2006). Pain and distress from needle-related procedures are common during childhood and can be reduced through use of psychological interventions (cognitive or behavioral strategies, or both). Our first review update (Issue 10, 2013) showed efficacy of distraction and hypnosis for needle-related pain and distress in children and adolescents.

OBJECTIVES

To assess the efficacy of psychological interventions for needle-related procedural pain and distress in children and adolescents.

SEARCH METHODS

We searched six electronic databases for relevant trials: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; PsycINFO; Embase; Web of Science (ISI Web of Knowledge); and Cumulative Index to Nursing and Allied Health Literature (CINAHL). We sent requests for additional studies to pediatric pain and child health electronic listservs. We also searched registries for relevant completed trials: clinicaltrials.gov; and World Health Organization International Clinical Trials Registry Platform (www.who.int.trialsearch). We conducted searches up to September 2017 to identify records published since the last review update in 2013.

SELECTION CRITERIA

We included peer-reviewed published randomized controlled trials (RCTs) with at least five participants per study arm, comparing a psychological intervention with a control or comparison group. Trials involved children aged two to 19 years undergoing any needle-related medical procedure.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data and assessed risks of bias using the Cochrane 'Risk of bias' tool. We examined pain and distress assessed by child self-report, observer global report, and behavioral measurement (primary outcomes). We also examined any reported physiological outcomes and adverse events (secondary outcomes). We used meta-analysis to assess the efficacy of identified psychological interventions relative to a comparator (i.e. no treatment, other active treatment, treatment as usual, or waitlist) for each outcome separately. We used Review Manager 5 software to compute standardized mean differences (SMDs) with 95% confidence intervals (CIs), and GRADE to assess the quality of the evidence.

MAIN RESULTS

We included 59 trials (20 new for this update) with 5550 participants. Needle procedures primarily included venipuncture, intravenous insertion, and vaccine injections. Studies included children aged two to 19 years, with few trials focused on adolescents. The most common psychological interventions were distraction (n = 32), combined cognitive behavioral therapy (CBT; n = 18), and hypnosis (n = 8). Preparation/information (n = 4), breathing (n = 4), suggestion (n = 3), and memory alteration (n = 1) were also included. Control groups were often 'standard care', which varied across studies. Across all studies, 'Risk of bias' scores indicated several domains at high or unclear risk, most notably allocation concealment, blinding of participants and outcome assessment, and selective reporting. We downgraded the quality of evidence largely due to serious study limitations, inconsistency, and imprecision.Very low- to low-quality evidence supported the efficacy of distraction for self-reported pain (n = 30, 2802 participants; SMD -0.56, 95% CI -0.78 to -0.33) and distress (n = 4, 426 participants; SMD -0.82, 95% CI -1.45 to -0.18), observer-reported pain (n = 11, 1512 participants; SMD -0.62, 95% CI -1.00 to -0.23) and distress (n = 5, 1067 participants; SMD -0.72, 95% CI -1.41 to -0.03), and behavioral distress (n = 7, 500 participants; SMD -0.44, 95% CI -0.84 to -0.04). Distraction was not efficacious for behavioral pain (n = 4, 309 participants; SMD -0.33, 95% CI -0.69 to 0.03). Very low-quality evidence indicated hypnosis was efficacious for reducing self-reported pain (n = 5, 176 participants; SMD -1.40, 95% CI -2.32 to -0.48) and distress (n = 5, 176 participants; SMD -2.53, 95% CI -3.93 to -1.12), and behavioral distress (n = 6, 193 participants; SMD -1.15, 95% CI -1.76 to -0.53), but not behavioral pain (n = 2, 69 participants; SMD -0.38, 95% CI -1.57 to 0.81). No studies assessed hypnosis for observer-reported pain and only one study assessed observer-reported distress. Very low- to low-quality evidence supported the efficacy of combined CBT for observer-reported pain (n = 4, 385 participants; SMD -0.52, 95% CI -0.73 to -0.30) and behavioral distress (n = 11, 1105 participants; SMD -0.40, 95% CI -0.67 to -0.14), but not self-reported pain (n = 14, 1359 participants; SMD -0.27, 95% CI -0.58 to 0.03), self-reported distress (n = 6, 234 participants; SMD -0.26, 95% CI -0.56 to 0.04), observer-reported distress (n = 6, 765 participants; SMD 0.08, 95% CI -0.34 to 0.50), or behavioral pain (n = 2, 95 participants; SMD -0.65, 95% CI -2.36 to 1.06). Very low-quality evidence showed efficacy of breathing interventions for self-reported pain (n = 4, 298 participants; SMD -1.04, 95% CI -1.86 to -0.22), but there were too few studies for meta-analysis of other outcomes. Very low-quality evidence revealed no effect for preparation/information (n = 4, 313 participants) or suggestion (n = 3, 218 participants) for any pain or distress outcome. Given only a single trial, we could draw no conclusions about memory alteration. Adverse events of respiratory difficulties were only reported in one breathing intervention.

AUTHORS' CONCLUSIONS

We identified evidence supporting the efficacy of distraction, hypnosis, combined CBT, and breathing interventions for reducing children's needle-related pain or distress, or both. Support for the efficacy of combined CBT and breathing interventions is new from our last review update due to the availability of new evidence. The quality of trials and overall evidence remains low to very low, underscoring the need for improved methodological rigor and trial reporting. Despite low-quality evidence, the potential benefits of reduced pain or distress or both support the evidence in favor of using these interventions in clinical practice.

Pain Assessment and Treatment in Children With Significant Impairment of the Central Nervous System

Pain is a frequent and significant problem for children with impairment of the central nervous system, with the highest frequency and severity occurring in children with the greatest impairment. Despite the significance of the problem, this population remains vulnerable to underrecognition and undertreatment of pain. Barriers to treatment may include uncertainty in identifying pain along with limited experience and fear with the use of medications for pain treatment. Behavioral pain-assessment tools are reviewed in this clinical report, along with other strategies for monitoring pain after an intervention. Sources of pain in this population include acute-onset pain attributable to tissue injury or inflammation resulting in nociceptive pain, with pain then expected to resolve after treatment directed at the source. Other sources can result in chronic intermittent pain that, for many, occurs on a weekly to daily basis, commonly attributed to gastroesophageal reflux, spasticity, and hip subluxation. Most challenging are pain sources attributable to the impaired central nervous system, requiring empirical medication trials directed at causes that cannot be identified by diagnostic tests, such as central neuropathic pain. Interventions reviewed include integrative therapies and medications, such as gabapentinoids, tricyclic antidepressants, α-agonists, and opioids. This clinical report aims to address, with evidence-based guidance, the inherent challenges with the goal to improve comfort throughout life in this vulnerable group of children.

The effect of slow-paced breathing on stress management in adolescents with intellectual disability

BACKGROUND

Intellectual disabilities often create a state of chronic stress for both the person concerned and their significant others (family, caregivers). The development of stress management methods is therefore important for the reduction of stress in persons with intellectual disability. The aim of this experiment was to investigate the effect of slow-paced breathing on stress symptoms experienced by adolescents with intellectual disabilities during a cognitive task under time pressure.

METHOD

Fourteen adolescents with intellectual disabilities (M_age  = 17.39 years, range 15-19 years) took part in two laboratory sessions - a slow-paced breathing session (experimental condition) and an audiobook session (control condition) - the order of which was counterbalanced across participants. Vagal tone was measured through heart rate variability to index stress management.

RESULTS

No difference in vagal tone was observed at baseline between experimental and control conditions. Compared with the control condition, vagal tone was significantly higher during the experimental condition.

CONCLUSIONS

The slow-paced breathing task enhanced stress management to a greater extent than did listening to an audiobook. Slow-paced breathing seems to be an easy to learn stress management technique that appears as an effective auxiliary method of lowering stress in adolescents with intellectual disabilities.

Psychological interventions in managing postoperative pain in children: a systematic review

Pediatric surgeries are common and painful for children. Postoperative pain is commonly managed with analgesics; however, pain is often still problematic. Despite evidence for psychological interventions for procedural pain, there is currently no evidence synthesis for psychological interventions in managing postoperative pain in children. The purpose of this review was to assess the efficacy of psychological interventions for postoperative pain in youth. Psychological interventions included Preparation/education, distraction/imagery, and mixed. Four databases (PsycINFO, PubMed, EMBASE, and Certified Index to Nursing and Allied Health Literature) were searched to July 2015 for published articles and dissertations. We screened 1401 citations and included 20 studies of youth aged 2 to 18 years undergoing surgery. Two reviewers independently screened articles, extracted data, and assessed risk of bias. Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated using RevMan 5.3. Fourteen studies (1096 participants) were included in meta-analyses. Primary outcome was pain intensity (0-10 metric). Results indicated that psychological interventions as a whole were effective in reducing children's self-reported pain in the short term (SMD = -0.47, 95% CI = -0.76 to -0.18). Subgroup analysis indicated that distraction/imagery interventions were effective in reducing self-reported pain in the short term (24 hours, SMD = -0.63, 95% CI = -1.04 to -0.23), whereas preparation/education interventions were not effective (SMD = -0.27, 95% CI = -0.61 to 0.08). Data on the effects of interventions on longer term pain outcomes were limited. Psychological interventions may be effective in reducing short-term postoperative pain intensity in children, as well as longer term pain and other outcomes (eg, adverse events) require further study.
