Audiovisual distraction for pain relief in paediatric inpatients: A crossover study

Awake biopsy in paediatric patients with suspected musculoskeletal malignancy is feasible, cost-effective and reduces time to obtaining tissue

AIM

This study aims to evaluate the utility, feasibility, time, and cost-effectiveness of awake ultrasound-guided percutaneous biopsies (AUPBs) in children with suspected musculoskeletal tumours, when compared with more conventional biopsies under general anaesthesia (BGAs).

MATERIALS AND METHODS

A retrospective analysis of paediatric biopsies performed in a UK tertiary musculoskeletal centre between March 2016 and March 2023 was undertaken. Eighty-six paediatric patients were included in the study, 53 undergoing BGA and 33 undergoing AUPB.

RESULTS

The mean age of patients undergoing AUPB was more than that of patients undergoing BGA at 13.2 years (range: 5-16 years) and 8.5 years (range: 3 months-15 years), respectively. AUPB significantly reduced the time to biopsy, with a mean of 4.7 days (median: 3 days, interquartile range [IQR]: 2-7 days), compared with 11.1 days (median: 5 days, IQR: 2-18 days) for BGAs (P = 0.037). AUPB conferred a one-third reduction in financial cost at £1177 vs £1824 for BGA. Fifty-eight percent patients undergoing AUPB had their biopsy on the same day as their initial assessment in clinic, whilst none of the BGA cases had their biopsy on the same day as their initial assessment in clinic. No complications or procedural abandonment were reported in the AUPB group.

CONCLUSION

Awake ultrasound-guided biopsy in paediatric musculoskeletal tumours is safe, well tolerated, and cost-effective. It reduces the time to obtain a histological diagnosis compared to BGA. Collaboration between clinicians, radiologists, and play specialists in identifying suitable patients for AUPB can facilitate efficient one-stop clinics and timely diagnosis and reduce costs incurred in paediatric oncological services.

Cartoon-assisted visual/auditory distraction usage in paediatric dental care, assessment of effects on patient anxiety, pain, and behaviour: a randomised crossover clinical trial

OBJECTIVES

This randomized crossover clinical trial designed to evaluate the impact of visual and auditory distraction techniques on pediatric patients' anxiety, pain perception, and behavior during dental treatment. The study specifically focuses on children, aiming to determine whether distraction methods can effectively reduce anxiety levels, alleviate pain experiences, and improve cooperative behavior in a clinical setting.

METHOD AND MATERIALS

Children aged 4 to 9 years receiving routine dental care at the Pediatric Dentistry Clinic, Istanbul Medipol University, were randomly assigned to Group 1 (distraction first, then tell-show-do) or Group 2 (tell-show-do first, then distraction), with a two-week washout period before switching interventions. Anxiety was assessed using the Venham Picture Test and pulse rate, pain perception with the Sounds, Eyes, and Motor Scale during local anesthesia and the Wong-Baker FACES Pain Rating Scale during treatment, while cooperation and behavior were evaluated using the Houpt Scale. Statistical analysis was conducted using Mann-Whitney U, Student's t-test, Paired t-test, and Wilcoxon test, with the significance level set at 0.025 using the Bonferroni correction.

RESULTS

Sixty-eight patients (37 female, 31 male) with a mean age of 6.69 ± 1.08 years completed the study (Group 1: n = 32, Group 2: n = 36). The cartoon-assisted distraction technique did not significantly reduce anxiety compared to the tell-show-do method. A non-significant reduction in pain perception was observed during local anesthesia with distraction. However, this technique significantly reduced self-reported pain during treatment (p < 0.025) and improved child cooperation and behavior.

CONCLUSION

Cartoon-assisted visual and auditory distraction can alleviate pain perception and improve behavior during pediatric dental procedures. However, it does not appear to reduce dental anxiety or pain perception during local anesthesia. Integrating this technique with the traditional tell-show-do approach may enhance the pediatric dental experience.

Analgosedation in Pediatric Emergency Care: A Comprehensive Scoping Review

Effective management of pain and anxiety in pediatric emergency room is crucial for ensuring both the physical and emotional well-being of young patients. Analgosedation, a combination of analgesia and sedation, is commonly used to facilitate various procedures in children. However, selecting the optimal agent and administration route remains challenging due to the unique pharmacological profiles and side effects of available drugs. This scoping review aims to provide a comprehensive analysis of the pharmacological agents used for procedural analgosedation in pediatric emergency settings, focusing on their efficacy, safety, administration routes, and potential side effects. A systematic review of the literature was conducted, focusing on key agents such as ketamine, midazolam, dexmedetomidine, fentanyl, and nitrous oxide. Studies were included based on their relevance to pediatric procedural sedation, particularly in emergency settings. Literature analysis showed that ketamine and fentanyl are effective for managing moderate to severe pain, with a rapid onset of action. Fentanyl is preferred for acute pain management following fractures and burns, while ketamine and midazolam are commonly used for emergency analgosedation. Dexmedetomidine, which induces sedation similar to natural sleep, is particularly effective in preventing pain and agitation during procedures and is well tolerated in children, especially those with developmental disorders. Nitrous oxide, when used in a 50% oxygen mixture, offers a valuable option for conscious sedation during mildly to moderately painful procedures, maintaining respiratory and airway reflexes. No single drug is ideal for all pediatric patients and procedures and the choice of agent should be tailored to the specific clinical scenario, considering both the sensory and affective components of pain. Future research should prioritize large-scale comparative studies, the exploration of combination therapies, and the development of non-pharmacological adjuncts to enhance the safety and efficacy of pediatric analgosedation.

Non-pharmacological interventions to reduce procedural needle pain in children (6-12 years): A systematic review

PROBLEM

Children of different age groups frequently undergo painful procedures involving needles, which can be a source of significant discomfort. Regrettably, this aspect of care often receives insufficient attention from healthcare professionals. The existing literature proposes several methodologies for managing procedural pain, with nonpharmacological techniques being particularly promising. These techniques should be adapted to the patient's age, but literature predominantly emphasizes their use with infants. Thus, it is necessary to evaluate their effectiveness in diverse age groups. Consequently, the purpose of this systematic review is to identify non-pharmacological interventions used to prevent needle-related procedural pain in children (age group 6-12 years).

ELIGIBILITY CRITERIA

Primary studies in English language on non-pharmacological interventions in children aged 6-12 years undergoing needle-related procedures found on PubMed, CINAHL and Embase.

SAMPLE

A total of 18 studies were included.

RESULTS

The results indicate the potential application of various non-pharmacological techniques, with distraction methods standing out. These techniques include activities like utilizing cards, watching cartoons, employing virtual reality and playing video games.

CONCLUSIONS

Children's procedural pain represents a significant challenge in treatment plans. Literature offers several approaches, including nonpharmacologic methods, to control this problem. Prioritizing procedural pain management is critical both at clinical and organizational levels to improve the quality of pediatric care.

IMPLICATIONS

These findings offer different options to support clinical practice, holding the potential to enhance the quality of patient care.

Venipuncture in pediatric emergency department by using Koala Attachment Distraction method: Randomized clinical trial

OBJECTIVE

To assess, compare and relate the toddler's pain and anxiety during venipuncture by using either the Koala Attachment Distraction method or the physical restraint method and to evaluate the level of anxiety perceived by the companions in both groups.

METHOD

Randomised, single-blind, controlled clinical trial in two arms (control and intervention group) conducted in the paediatric emergency department of a tertiary university hospital. The study variables were pain and stress of the child and anxiety perceived by the accompanying persons in both groups at the time before and during the technique. The pain rating scale Face, Leg, Activity, Cry, Consolability; the Groningen stress scale and the STAI questionnaire were used.

RESULTS

A total of 113 participants aged 3 to 4 years participated in the trial (n=113). 50% (55) were girls, mean total age 3.83±0.59 years and accompanying persons 37.17±6.96. During the technique the mean pain in control and intervention groups was 5.64±3.30 and 3.87±3.01; stress, 3.25±1.22 and 2.67±1.24, respectively. No statistically significant differences were found in the assessment of anxiety between the groups.

CONCLUSIONS

Patients who underwent the Koala Attachment Distraction method venipuncture show a lower level of pain and anxiety than those who received physical restraint, and the anxiety perceived by the companion is similar in both groups.

Effectiveness of Nonpharmacological Behavioural Interventions in Managing Dental Fear and Anxiety among Children: A Systematic Review and Meta-Analysis

BACKGROUND

Non-pharmacological behavioural interventions (NPBIs) have been employed by dentists to alleviate dental fear and anxiety (DFA) among preschool and school children. The aim of this systematic review and meta-analysis was to investigate the effectiveness of different NPBIs in reducing DFA among children aged below 12.

METHOD

A comprehensive search was conducted using four electronic databases to identify randomised controlled trials that assess the effectiveness of NPBIs among preschool and school children. Two reviewers independently screened and selected the relevant studies, evaluated the risk of bias, and extracted relevant data for qualitative and quantitative syntheses.

RESULT

A total of 66 articles were included in the study. Except during more invasive dental procedures, the use of distraction techniques was found to result in significantly lower self-rated anxiety, better cooperation, and lower pulse rate compared to the tell-show-do method. However, inconsistent results were reported regarding the efficacy of virtual reality, modelling, visual pedagogies, tell-show-do and other NPBIs in reducing DFA among children.

CONCLUSIONS

The studies exhibited substantial heterogeneity due to varying age groups, methods of implementing NPBIs, dental treatments performed, and measurement scales employed in the evaluation of DFA.

Nurses’ Perceptions of the Quality of Procedural Sedation in Children Comparing Different Pharmacological Regimens

Nurses play a pivotal role during pediatric procedural sedation and their perspective is an important indicator for the quality of care. The aim of this study is to examine nurses’ satisfaction comparing four different pharmacological regimens used for pediatric sedation outside of the operating room. A prospective observational study was conducted in a third-level pediatric teaching hospital, involving all the nurses with experience in the field of pediatric procedural sedation. A 13-item survey was used to assess the level of nurses’ satisfaction for the quality of sedation with four different analgesic–sedative drugs. Fifty-one questionnaires were completed by pediatric nurses, with a median length of experience of 10 years. Regarding the overall quality of the sedation, the highest median satisfaction scores were observed for propofol (8, IQR 7–9), dexmedetomidine (8, IQR 6–8) and midazolam (8, IQR 7–9). Ketamine (5, IQR 3–7) displayed the lowest score. When asked to rate their level of perceived safety, nurses gave high scores to all the four drugs studied, with no statistically significant difference between them. Non-pharmacological techniques during procedural sedation were judged as important by 38 (74.5%) nurses. According to this sample of pediatric nurses, the best quality of procedural sedation in children outside of the operating room is obtained with propofol, dexmedetomidine and midazolam. During procedural sedation, nurses feel safe overall, regardless of the pharmacological regimen used. Moreover, they highlighted the relevance on non-pharmacological approaches in the preparation of the child for the procedure.

Comparing Auditory and Visual Distractions for Reducing Pain Severity and Pain Anxiety in Older Outpatients with Burn: A Randomized Controlled Trial

Pain and anxiety are major issues among older patients with burn injuries. Complementary medicine and non-pharmacological methods can relieve pain and anxiety in older people, but comparison of the effects of these methods needs further research. This study aimed to compare the effects of auditory and visual distractions on pain severity and pain anxiety in older outpatients referred to a burn clinic for dressing change. In this randomized controlled clinical trial, older men were randomly assigned to three groups as auditory distraction, visual distraction, and control (n = 45 in each group). The Visual Analogue Scale (VAS) and the Burn Specific Pain Anxiety Scale (BSPAS) were used to asses pain severity and pain anxiety before and immediately after the interventions, and after wound dressing. Reduction in pain severity and pain anxiety after visual distraction was reported. Auditory distraction only reduced pain anxiety. Therefore, visual distraction had a better effect on alleviating pain anxiety compared with auditory distraction. Visual distraction is suggested to be used during dressing changes for older outpatients with burn injuries in outpatient clinics in order to reduce their burn-related suffering and improve their collaboration with the therapeutic regimen.

Burn patients' pain experiences and perceptions

INTRODUCTION

Burns are painful injuries associated with a long recovery. Patients may not be receiving sufficient pain management education to optimize their experience and recovery after burn injury. Therefore, we aimed to obtain patients' perspectives about the effectiveness of current burn pain education to inform future efforts.

METHODS

We used a mixed-methods research design that included both inpatients and outpatients cared for at a single, American Burn Association-verified burn center. Participants were at least 14 years of age with an acute burn who received a minimum of two wound interventions. The interview was designed by clinician stakeholders using a modified Delphi technique and focused on patient respondent's pain experience, understanding and desire to gain knowledge concerning burn pain and its management. Descriptive quantitative analysis was performed on categorical data. Recorded interview segments were transcribed for content analysis.

RESULTS

Twenty-one adult burn patients were interviewed. Participants reported experiencing variable levels of pain and pain management effectiveness. Inpatients reported more severe pain than outpatients. Only 11% of inpatients reported having received enough pain information, compared to 50% of outpatients. Content analysis yielded 3 themes: patient's pain experience, range of expectations, and clinical information/services desired. Mental and physical effects were key factors in respondents' pain experiences, with many participants reporting mental anguish in addition to pain. Of participants who had pain expectations, most were matched by their experience (56%), although many individuals (44%) described higher pain levels than they anticipated. Positive experiences with the burn care team primarily revolved around receiving pain education from a provider, whereas negative experiences focused on wound care events. Participants desired more information on sleep and pain medications, alternative treatments, weaning and addiction risk, realistic expectations of recovery timelines, and available mental health services. Written (pamphlet) education ranked as the most desirable delivery method, followed by in-person and video education.

CONCLUSIONS

Burn patients reported variable pain experiences and a strong desire to receive additional pain education. This project informs key strategies to educate burn patients on pain: leverage the high-level of interest in pain to foster education, describe pharmacologic and alternative therapies, offer weaning plans and explanation of addiction risks.

APPLICABILITY TO PRACTICE

Burn patients' perspectives help inform strategies and content creation for pain-related education materials that burn centers can provide to improve patients' experiences.

Intranasal drugs for analgesia and sedation in children admitted to pediatric emergency department: a narrative review

Acute pain is one of the most common symptoms in children admitted to the Pediatric Emergency Department (PED) and its management represents a real clinical challenge for pediatricians. Different painful procedures can be very stressful for young children and their perception of pain can be enhanced by emotional factors, such as anxiety, distress, or anger. Adequate procedural sedation reduces anxiety and emotional trauma for the patient, but it reduces also stress for operators and the time for procedures. We have reviewed the literature on this topic and the drugs covered in these papers were: midazolam, fentanyl, ketamine, and dexmedetomidine. There are several routes of administering for these drugs to provide analgesia and anxiolysis to children: oral, parenteral, or intranasal (IN). Intravenous (IV) sedation, since it involves the use of needles, can be stressful; instead, IN route is a non-invasive procedure and generally well tolerated by children and it has become increasingly widespread. Some medications can be administered by a mucosal atomizer device (MAD) or by drops. The benefits of the atomized release include less drug loss in the oropharynx, higher cerebrospinal fluid levels, better patient acceptability, and better sedative effects. IN midazolam has a sedative, anxiolytic and amnesic effect, but without analgesic properties. Fentanyl and ketamine are mainly used for pain control. Dexmedetomidine has anxiolytic and analgesic properties. In conclusion, IN analgo-sedation is a simple, rapid and painless option to treat pain and anxiety in the PED requiring brief training on the administration process and experience in sedation.

Comparison of the Effects of Visual and Auditory Distractions on Fistula Cannulation Pain among Older Patients Undergoing Hemodialysis: A Randomized Controlled Clinical Trial

Pain associated with fistula cannulation is a challenge for nurses who provide care to older patients undergoing hemodialysis. Several non-pharmacological methods have been suggested for relieving fistula cannulation pain, but the benefits of visual and auditory distraction methods among older patients undergoing hemodialysis have not been investigated yet. Therefore, this study aimed to compare the effects of visual and auditory distractions on fistula cannulation pain among older patients undergoing hemodialysis. This randomized controlled clinical trial was conducted on 120 older patients undergoing hemodialysis. They were randomly assigned to three groups of visual distraction, auditory distraction, and the control (n = 40 in each group) using a simple random assignment method. The distraction interventions continued for three consecutive sessions and the numeric rating scale of pain severity was used for data collection. Descriptive and inferential statistics were used for data analysis using SPSS. It was found that pain severity significantly reduced after the distraction interventions in either the auditory or visual distraction groups and also after all three distraction sessions (p = 0.001). However, visual distraction had a better effect on the reduction of pain severity. Therefore, while both visual and auditory distractions reduced pain severity in older patients undergoing hemodialysis, visual distraction was more effective. Nurses are encouraged to incorporate visual distraction as a safe and non-pharmacologic technique into routine nursing care for reducing older patients’ suffering and improving their wellbeing when fistula cannulation is performed.

The expanded endonasal approach in pediatric skull base surgery: A review

OBJECTIVE

Surgery of the pediatric skull base has multiple unique challenges and has seen recent rapid advances. The objective of this review is to assess key issues in pediatric skull base surgery (SBS), including anatomic limitations, surgical approaches, reconstruction techniques, postoperative care, complications, and outcomes.

DATA SOURCES

PubMed literature review.

REVIEW METHODS

A review of the literature was conducted to assess the challenges, recent advances, and reported outcomes in pediatric SBS.

RESULTS

The pediatric skull base presents multiple anatomic challenges, including variable patterns of pneumatization, narrow piriform aperture width, and narrow intercarotid distance at the level of the cavernous sinus but not the superior clivus. These issues may be particularly challenging in patients less than 2 years of age. Endoscopic endonasal approaches in the sagittal and coronal plane have been applied to the pediatric skull base while open approaches may still be necessary in the setting of extensive intracranial or orbital disease, as well as disease lateral to critical neurovascular structures. While the nasoseptal flap was initially called into question for pediatric cases, it has been shown through multiple reports to be a feasible and robust reconstructive option. Complications and outcomes often depend upon the pathology. In children, response to noxious stimuli, ability to avoid Valsalva, and adherence to nasal precautions is variable. The use of lumbar drains is more common in pediatric than adult patients.

CONCLUSION

While the pediatric skull base presents unique challenges, outcomes data support that endoscopic endonasal approaches are a pertinent surgical technique in appropriately selected patients.

Digital Technology Distraction for Acute Pain in Children: A Meta-analysis

CONTEXT

Digital distraction is being integrated into pediatric pain care, but its efficacy is currently unknown.

OBJECTIVE

To determine the effect of digital technology distraction on pain and distress in children experiencing acutely painful conditions or procedures.

DATA SOURCES

Medline, Embase, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Institute of Electrical and Electronics Engineers Xplore, Ei Compendex, Web of Science, and gray literature sources.

STUDY SELECTION

Quantitative studies of digital technology distraction for acutely painful conditions or procedures in children.

DATA EXTRACTION

Performed by 1 reviewer with verification. Outcomes were child pain and distress.

RESULTS

There were 106 studies (n = 7820) that reported on digital technology distractors (eg, virtual reality and video games) used during common procedures (eg, venipuncture, dental, and burn treatments). No studies reported on painful conditions. For painful procedures, digital distraction resulted in a modest but clinically important reduction in self-reported pain (standardized mean difference [SMD] -0.48; 95% confidence interval [CI] -0.66 to -0.29; 46 randomized controlled trials [RCTs]; n = 3200), observer-reported pain (SMD -0.68; 95% CI -0.91 to -0.45; 17 RCTs; n = 1199), behavioral pain (SMD -0.57; 95% CI -0.94 to -0.19; 19 RCTs; n = 1173), self-reported distress (SMD -0.49; 95% CI -0.70 to -0.27; 19 RCTs; n = 1818), observer-reported distress (SMD -0.47; 95% CI -0.77 to -0.17; 10 RCTs; n = 826), and behavioral distress (SMD -0.35; 95% CI -0.59 to -0.12; 17 RCTs; n = 1264) compared with usual care.

LIMITATIONS

Few studies directly compared different distractors or provided subgroup data to inform applicability.

CONCLUSIONS

Digital distraction provides modest pain and distress reduction for children undergoing painful procedures; its superiority over nondigital distractors is not established. Context, preferences, and availability should inform the choice of distractor.

EMDR and Nonpharmacological Techniques for Anxiety Prevention in Children Prior to Invasive Medical Procedures: A Randomized Controlled Trial

Nonpharmacological Techniques (NPT) have been suggested as an efficient and safe means to reduce pain and anxiety in invasive medical procedures. Due to the anxious and potentially traumatic nature of these procedures, we decided to integrate an eye movement desensitization and reprocessing (EMDR) session in the preprocedure NPT. The main purpose of this study was to evaluate the efficacy of one session of EMDR in addition to the routine NPT. Forty-nine pediatric patients (Male = 25; Female = 24) aged 8–18 years (M = 13.17; SD = 2.98) undergoing painful and invasive medical procedures were randomized to receive standard preprocedural care (N = 25) or a session of EMDR in addition to the standard nonpharmacological interventions (N = 24). Participants completed the anxiety and depression scales from the Italian Psychiatric Self-evaluation Scale for Children and Adolescents (SAFA) and rated anxiety on a 0–10 numeric rating scale. Participants in the NPT+EMDR condition expressed significantly less anxiety before the medical procedure than those in the NPT group (p = .038). The integration of EMDR with NPT was demonstrated to be an effective anxiety prevention technique for pediatric sedo-analgesia. These results are the first data on the efficacy of EMDR as a technique to prevent anxiety in pediatric sedo-analgesia. There are important long-term clinical implications because this therapy allows an intervention on situations at risk of future morbidity and the prevention of severe disorders.

Cognitive Processing Styles and Mindfulness on Pain Intensity Prediction in People with Primary Headache

Background

Primary headaches are the most common cause of absence from work and school and one of the most common reasons for referring to the neurologists.

Objectives

The present study was designed to investigate the relationship of cognitive processing style and mindfulness with pain intensity and the ultimate aim was to provide the role of pain-related cognitive processes and mindfulness in the prediction of headache intensity.

Methods

The study was conducted descriptively by using the correlation method. The statistical population of this study was composed of 85 patients (56 females and 29 males) with one type of primary headache, which were selected through purposive sampling after the diagnosis of a headache by a neurologist at Imam Hossein Hospital in Tehran province. To measure the variables of the study, the numeric pain rating scale (NRS) and the pain-related cognitive processes questionnaire (PCPQ) were used. All data were analyzed using descriptive statistics (frequency and percentages). Bivariate correlation matrix and hierarchical stepwise linear regression statistics were used.

Results

The results showed that there was a significant and negative association between pain intensity (NRS) and mindfulness (P < 0.01) and all pain-related cognitive processes, except pain focus (P < 0.01). The results of stepwise linear regression indicated that mindfulness only explains 39% of total score changes in pain intensity (P < 0.05 and ΔF (1 and 83) = 53.63, ΔR = 0.385). Adding cognitive processing styles to the model led to an 18% increase of the explained variance (R² change = 0.179). In total, the present research model justifies 54% of the severity of headache variance (P < 0.01, ΔR = 0.54).

Conclusions

The results suggest that pain-related cognitive processes and mindfulness are effective on pain intensity prediction. In other words, this result can explain the role of mindfulness and adaptive cognitive processing in primary headache pain management.

Effects of watching cartoons on pain scores in children undergoing venepuncture

BACKGROUND

Children experience pain and restlessness during invasive procedures.

AIM

To determine the effect of watching cartoons on pain scores and the duration of crying in children aged 3-6 years undergoing venepuncture.

METHOD

The study included 81 children, aged 3-6 years, who presented to the blood collection unit of a teaching and research hospital. The children were divided into an experimental group (n=41) and a control group (n=40). Those in the experimental group watched a cartoon and then venepuncture was initiated. Their pain levels and the duration of crying were assessed during venepuncture. After venepuncture, they continued to watch the cartoons and their pain levels were assessed again. During the process, another researcher calculated the duration of crying. The children in the control group were subjected to the same process but were not shown the cartoon.

RESULTS

Significant differences in pain levels, duration of crying after the procedure and total duration of crying were found between the groups. There was no significant difference in terms of duration of crying during the procedure.

CONCLUSION

Watching cartoons is a non-pharmacological method of pain relief, which reduces perception of pain by distracting a child's attention.

Pain in Mucopolysaccharidoses: Analysis of the Problem and Possible Treatments

Mucopolysaccharidosis (MPS) are a group of lysosomal storage disorders that are caused by the deficiency of enzymes involving in the catabolism of glycosaminoglycan (GAGs). GAGs incompletely degraded accumulate in many sites, damaging tissues and cells, leading to a variety of clinical manifestations. Many of these manifestations are painful, but few data are available in the literature concerning the prevalence, etiology, and pathogenesis of pain in children with MPS. This review, through the analysis of the data available the in literature, underscores the relevant prevalence of pain in MPSs’ children, provides the instruments to discern the etiopathogenesis of the disease and of pain, illustrates the available molecules for the management of pain and the possible advantages of non-pharmacological pain therapy in MPSs’ patients.

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.

Effects of audiovisual distraction in children with special healthcare needs during dental restorations: a randomized crossover clinical trial

BACKGROUND

Audiovisual distraction using video eyeglasses is useful in managing distress and reducing fear and anxiety in healthy children during dental treatments.

AIM

To evaluate the effect of audiovisual distraction on behavior and self-reported pain of children with special healthcare needs (SHCN) without intellectual disability during dental restorations and its influence on the operator stress and the time of the appointment.

MATERIAL AND METHODS

This randomized controlled crossover trial comprised 48 children with SHCN requiring at least two dental restorations. One restoration was done wearing the video eyeglasses and one wearing conventional behavior management techniques. Subjective and objective pain was evaluated using the Faces Pain Scale - Revised (FPS-R) and the revised Face, Leg, Activity, Cry, and Consolability scale (r-FLACC). The operator stress using a VAS, the time of the appointment, and the child satisfaction were recorded.

RESULTS

The use of video eyeglasses significantly reduced the operator stress. The bivariate analysis showed that the mean FPS-R score and the mean r-FLACC score were significantly lower using the video eyeglasses only during the second clinical session.

CONCLUSION

Audiovisual distraction could be useful in managing distress in SHCN children without intellectual disability but cannot replace the conventional behavior management techniques.

A psychological intervention proposal on coping with pain for children with Sickle Cell Disease

Abstract Pain is common in Sickle Cell Disease. This study proposes a Psychological Intervention Program for Children with Sickle Cell Disease (Intervenção Psicológica para Crianças com Anemia Falciforme). It was applied to seven children in a hospital. The intervention was based in the Motivational Theory of Coping and includes the Coping with Pain Game (Jogo “Enfrentando a Dor”). The Computerized Assessment Instrument of Coping with Hospitalization-Pain (Instrumento Computadorizado para Avaliação do Enfrentamento da Hospitalização-Dor) was applied before and after seven weekly sessions. The results showed significant increase in the facilitating behaviors to cope with pain, and in problem-solving, an adaptive coping; and a reduction in the non-facilitating behaviors and in rumination, a maladaptive coping. The stressor perception as a challenge to the need of competence increased, whereas the stressor perception as a threat to the need of competence and autonomy decreased. This intervention may have contributed to promote adaptive coping with pain.
