The Cochrane Library and procedural pain in children: an overview of reviews

Invasive procedures and atraumatic care in pediatric nursing practice: nurses' perceptions

Introduction

Invasive procedures in pediatric nursing practice require a child-centered approach to minimize pain levels associated with manifestations of stress, anxiety, and long-term traumatic reactions.

Method

This cross-sectional study aimed at identifying nurses' perception of stress, anxiety, and pain levels in children and adolescents (0-18 years) undergoing invasive procedures, and strategies used to minimize the associated distress. Based on a literature review, an online questionnaire was developed that evaluates the distress associated with frequent invasive procedures and strategies used to reduce discomfort.

Results

Participants were 157 nurses who provided nursing care to children in all types of healthcare settings, such as hospitals and community health centers. Nurses evaluated lumbar puncture and catheter insertion as the procedures that caused more stress, anxiety, and pain in all age groups. ANOVA and post-hoc analyses indicate that nurses perceived adolescents as experiencing less stress than children in all the invasive procedures. Pediatric specialist nurses perceived a significantly higher total level of distress (an index that indicates stress, anxiety or pain in the whole group of procedures) compared to nurses with other specialties or generalist nurses, in all age groups. Non-pharmacological strategies were the most frequently used strategies used by nurses for minimizing distress in children, including distraction (51.2%), preparation (30.7%), and sensory techniques (14.6%). Pharmacological strategies, such as topical anesthetics and light sedation, were less frequently used.

Conclusion

This study highlights the importance of specialized training and knowledge concerning strategies to reduce distress in pediatric invasive procedures, suggesting the need for more significant investment in education and support for nursing professionals to improve patient experience.

Developments in the Design, Conduct, and Reporting of Child Health Trials

To identify priority areas to improve the design, conduct, and reporting of pediatric clinical trials, the international expert network, Standards for Research (StaR) in Child Health, was assembled and published the first 6 Standards in Pediatrics in 2012. After a recent review summarizing the 247 publications by StaR Child Health authors that highlight research practices that add value and reduce research "waste," the current review assesses the progress in key child health trial methods areas: consent and recruitment, containing risk of bias, roles of data monitoring committees, appropriate sample size calculations, outcome selection and measurement, and age groups for pediatric trials. Although meaningful change has occurred within the child health research ecosystem, measurable progress is still disappointingly slow. In this context, we identify and review emerging trends that will advance the agenda of increased clinical usefulness of pediatric trials, including patient and public engagement, Bayesian statistical approaches, adaptive designs, and platform trials. We explore how implementation science approaches could be applied to effect measurable improvements in the design, conducted, and reporting of child health research.

Virtual reality hypnosis for needle-related procedural pain and fear management in children: a non-inferiority randomized trial

Needle-related procedures can cause pain and fear in children and may lead to avoidance of future medical care. The aim of this study is to investigate whether virtual reality hypnosis (VRH) is non-inferior to medical hypnosis (MH) by a trained healthcare provider in reducing pain in children. This non-inferiority randomized trial was conducted at a teaching hospital in the Netherlands. Children aged 6 to 18 years were randomized to treatment with VRH or MH. The primary outcome was self-reported pain, using the Wong-Baker FACES Scale (WBFS) with the non-inferiority margin defined as a difference of 1.5 points. Secondary outcomes included observer-reported pain (Numeric Rating Scale), fear (scored by children and observers with the Children's Fear Scale), blood pressure, heart rate, treatment satisfaction, and adverse effects. We randomized 138 children to VRH or MH treatment and included 114 children in the analyses (VRH n = 60, MH n = 54). We found non-inferiority for VRH compared to MH on patient-reported pain (mean difference =  - 0.17, 95%CI - 1.01;0.66). Secondary outcomes were comparable between VRH and MH groups. Both treatments scored high on patient satisfaction (VRH median = 9.0, MH median = 10.0, p = 0.512).

CONCLUSION

VRH may be an effective and safe treatment option besides MH for reducing patient-reported pain in children during a needle-related procedure. VRH was non-inferior to MH in patient-reported fear and both treatments were comparable in terms of patient-reported fear, observer-reported pain and fear, physical distress, and patient satisfaction.

Animal-Assisted Psychotherapy for Pediatric Chronic Pain: Case Series of an Open Pilot Study to Test Initial Feasibility and Potential Efficacy

Objective

Chronic pain is a common complaint in children and adolescents, placing an enormous burden on individuals, their families, and the healthcare system. New innovative approaches for the treatment of pediatric chronic pain (PCP) are clearly warranted, as drop-out rates in intervention studies are high and it can be difficult to engage patients with PCP in therapy. Here, animal-assisted interventions (AAIs) might be promising, since there is preliminary evidence for the approach in adults with chronic pain, and AAIs are generally known to foster the therapeutic motivation of patients. To date, however, AAIs have not been examined in pediatric chronic pain.

Methods

The aim of this open pilot study was to examine the initial feasibility of recruitment and potential efficacy of an animal-assisted group psychotherapy (including horses, rabbits, chickens, goats, and a dog), providing case reports of three children with chronic pain. We applied a mixed-methods approach, including the conductance of semi-structured interviews and assessment of quantitative pre-post data with a focus on pain severity, avoidance behavior, pain acceptance, and ability to defocus from the pain.

Results

The three participating girls (age: 9-12 years) reported chronic pain in the head and abdomen. The process of recruitment turned out to be challenging. All three children reported reduced pain-related disability and pain-related distress, as well as an increased ability to accept pain and to defocus from the pain. The qualitative data revealed that patients and their parents had a positive attitude towards AAIs.

Conclusion

Our initial open pilot study is the first to investigate AAIs in the context of pediatric chronic pain. Notably, we had difficulties in the recruitment procedure, mostly due to the Covid-19 situation. Based on three case reports, we found some first indication that AAI approaches might be associated with symptom changes. Future randomized-control studies with larger sample sizes are clearly warranted.

Evaluation and Treatment of Pain in Fetuses, Neonates and Children

The perception of pain is individual and differs between children and adults. The structures required to feel pain are developed at 24 weeks of gestation. However, pain assessment is complicated, especially in neonates, infants and preschool-age children. Clinical scales adapted to age are the most used methods for assessing and monitoring the degree of pain in children. They evaluate several behavioral and/or physiological parameters related to pain. Some monitors detect the physiological changes that occur in association with painful stimuli, but they do not yet have a clear clinical use. Multimodal analgesia is recommended for pain treatment with non-pharmacological and pharmacological interventions. It is necessary to establish pharmacotherapeutic protocols for analgesia adjusted to the acute or chronic, type and intensity of pain, as well as age. The most used analgesics in children are paracetamol, ibuprofen, dipyrone, opioids (morphine and fentanyl) and local anesthetics. Patient-controlled analgesia is an adequate alternative for adolescent and older children in specific situations, such as after surgery. In patients with severe or persistent pain, it is very important to consult with specific pain services.

Effectiveness of biofeedback relaxation and audio-visual distraction on dental anxiety among 7- to 12-year-old children while administering local anaesthesia: A randomized clinical trial

BACKGROUND

Local anaesthesia (LA) administration provokes dental anxiety in children. BrightHearts is a biofeedback relaxation application designed to reduce anxiety in children during painful procedural interventions.

AIM

To compare the effectiveness of biofeedback relaxation (BR) and audio-visual (AV) distraction on dental anxiety among 7- to 12-year-old children while administering LA.

DESIGN

A total of 70 children requiring dental treatment under LA for three visits were recruited for this single-blinded randomized control trial. They were randomly divided into two equal groups. Group A received BR and Group B received AV distraction during LA delivery in the first two visits, and both groups did not receive any intervention during LA in third visit. Outcomes were measured using heart rate and a cartoon-based anxiety measuring scale (Chotta Bheem-Chutki (CBC) scale).

RESULTS

AV group had statistically significant higher mean heart rates than BR group (P < .001) during needle penetration and post-intervention, respectively. CBC scale showed no statistical differences between the groups.

CONCLUSION

Both the interventions are effective in reducing dental anxiety during LA administration. Based on objective measures, BR is found to be better than AV distraction. Subjective scores, however, show no differences between the two.

Effect of Distraction Intervention for Needle-Related Pain and Distress in Children: A Systematic Review and Meta-Analysis

A systematic review and meta-analysis conducted to evaluate the combined effect of distraction intervention for needle-related pain in order to provide the basis for developing an effective nursing intervention for children. We searched three electronic databases, PubMed, Embase, and CINAHL, for original articles published in the period from 1 January 2011 to 31 July 2019. In addition, a manual search was performed on the basis of references in the literature and the references of the articles in pursuit of comprehensive data until 10 December 2019. Meta-analysis was performed by the synthesis of the effect size, homogeneity, heterogeneity, and trim-and-fill method using MIX 2.0 Pro. Well-planned RCTs, single-center studies, high-quality studies, participants older than 10 years of age, and visual and clown distraction interventions were effective for needle-related pain and distress management among children. The results showed evidence supporting the effect of distraction interventions for children’s needle-related pain and distress. Through this review, strategies were identified to design better interventions to improve the outcomes.

Pediatric Critical Care Nurses' Practices Related to Sedation and Analgesia

BACKGROUND

Pediatric intensive care unit (PICU) nurses may consider additional factors beyond validated tools when managing pain and sedation of children. However, these other factors and related beliefs, practices, and decision-making for analgesia and sedation have not been well described.

OBJECTIVES

This study describes nurses' beliefs, practices, and decision-making related to sedation and analgesia for mechanically ventilated children on a PICU and a pediatric cardiovascular ICU at a tertiary academic children's medical center in the United States.

METHODS

A 35-item web-based survey tool was developed to more fully identify nurses' pain, sedation, comfort, and analgesia beliefs, decisions, planning, and procedures for children who were mechanically ventilated in the ICU. It was distributed to 102 nurses in the PICU, pediatric cardiovascular ICU, and pediatric critical care float pool.

RESULTS

Twenty-six nurses (25%) responded; a majority worked the night shift and had 5 years or less of ICU experience. While participants believed intubated pediatric patients required moderate to deep sedation, approximately only half reported patients were adequately sedated. They reported that they were more likely to manage pain and sedation using specific behaviors and changes in vital signs than scores on a standardized scale. Nurses also reported routinely incorporating nonpharmacologic comfort measures. Premedication was more common for invasive procedures than for routine nursing care.

DISCUSSION

Pediatric ICU nurses in this study considered factors beyond standardized scales when evaluating and managing pain and sedation of ventilated children. Nurses prioritized children's specific behaviors, vital signs, and their own nursing judgment above standardized scales. Research is needed to describe nurses' practices beyond this small study and to define and validate additional assessment parameters to incorporate into decision-making to improve management and care outcomes.

Virtual reality distraction for acute pain in children

BACKGROUND

Virtual reality (VR) computer technology creates a simulated environment, perceived as comparable to the real world, with which users can actively interact. The effectiveness of VR distraction on acute pain intensity in children is uncertain.

OBJECTIVES

To assess the effectiveness and adverse effects of virtual reality (VR) distraction interventions for children (0 to 18 years) with acute pain in any healthcare setting.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO and four trial registries to October 2019. We also searched reference lists of eligible studies, handsearched relevant journals and contacted study authors.

SELECTION CRITERIA

Randomised controlled trials (RCTs), including cross-over and cluster-RCTs, comparing VR distraction to no distraction, non-VR distraction or other VR distraction.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological processes. Two reviewers assessed risk of bias and extracted data independently. The primary outcome was acute pain intensity (during procedure, and up to one hour post-procedure). Secondary outcomes were adverse effects, child satisfaction with VR, pain-related distress, parent anxiety, rescue analgesia and cost. We used GRADE and created 'Summary of findings' tables.

MAIN RESULTS

We included 17 RCTs (1008 participants aged four to 18 years) undergoing various procedures in healthcare settings. We did not pool data because the heterogeneity in population (i.e. diverse ages and developmental stages of children and their different perceptions and reactions to pain) and variations in procedural conditions (e.g. phlebotomy, burn wound dressings, physical therapy sessions), and consequent level of pain experienced, made statistical pooling of data impossible. We narratively describe results. We judged most studies to be at unclear risk of selection bias, high risk of performance and detection bias, and high risk of bias for small sample sizes. Across all comparisons and outcomes, we downgraded the certainty of evidence to low or very low due to serious study limitations and serious or very serious indirectness. We also downgraded some of the evidence for very serious imprecision. 1: VR distraction versus no distraction Acute pain intensity: during procedure Self-report: one study (42 participants) found no beneficial effect of non-immersive VR (very low-certainty evidence). Observer-report: no data. Behavioural measurements (observer-report): two studies, 62 participants; low-certainty evidence. One study (n = 42) found no beneficial effect of non-immersive VR. One study (n = 20) found a beneficial effect favouring immersive VR. Acute pain intensity: post-procedure Self-report: 10 studies, 461 participants; very low-certainty evidence. Four studies (n = 95) found no beneficial effect of immersive and semi-immersive or non-immersive VR. Five studies (n = 357) found a beneficial effect favouring immersive VR. Another study (n = 9) reported less pain in the VR group. Observer-report: two studies (216 participants; low-certainty evidence) found a beneficial effect of immersive VR, as reported by primary caregiver/parents or nurses. One study (n = 80) found a beneficial effect of immersive VR, as reported by researchers. Behavioural measurements (observer-report): one study (42 participants) found no beneficial effect of non-immersive VR (very low-certainty evidence). Adverse effects: five studies, 154 participants; very low-certainty evidence. Three studies (n = 53) reported no adverse effects. Two studies (n = 101) reported mild adverse effects (e.g. nausea) in the VR group. 2: VR distraction versus other non-VR distraction Acute pain intensity: during procedure Self-report, observer-report and behavioural measurements (observer-report): two studies, 106 participants: Self-report: one study (n = 65) found a beneficial effect favouring immersive VR and one (n = 41) found no evidence of a difference in mean pain change scores (very low-certainty evidence). Observer-report: one study (n = 65) found a beneficial effect favouring immersive VR and one (n = 41) found no evidence of a difference in mean pain change scores (low-certainty evidence). Behavioural measurements (observer-report): one study (n = 65) found a beneficial effect favouring immersive VR and one (n = 41) reported a difference in mean pain change scores with fewer pain behaviours in VR group (low-certainty evidence). Acute pain intensity: post-procedure Self-report: eight studies, 575 participants; very low-certainty evidence. Two studies (n = 146) found a beneficial effect favouring immersive VR. Two studies (n = 252) reported a between-group difference favouring immersive VR. One study (n = 59) found no beneficial effect of immersive VR versus television and Child Life non-VR distraction. One study (n = 18) found no beneficial effect of semi-immersive VR. Two studies (n = 100) reported no between-group difference. Observer-report: three studies, 187 participants; low-certainty evidence. One study (n = 81) found a beneficial effect favouring immersive VR for parent, nurse and researcher reports. One study (n = 65) found a beneficial effect favouring immersive VR for caregiver reports. Another study (n = 41) reported no evidence of a difference in mean pain change scores. Behavioural measurements (observer-report): two studies, 106 participants; low-certainty evidence. One study (n = 65) found a beneficial effect favouring immersive VR. Another study (n = 41) reported no evidence of a difference in mean pain change scores. Adverse effects: six studies, 429 participants; very low-certainty evidence. Three studies (n = 229) found no evidence of a difference between groups. Two studies (n = 141) reported no adverse effects in VR group. One study (n = 59) reported no beneficial effect in reducing estimated cyber-sickness before and after VR immersion. 3: VR distraction versus other VR distraction We did not identify any studies for this comparison.

AUTHORS' CONCLUSIONS

We found low-certainty and very low-certainty evidence of the effectiveness of VR distraction compared to no distraction or other non-VR distraction in reducing acute pain intensity in children in any healthcare setting. This level of uncertainty makes it difficult to interpret the benefits or lack of benefits of VR distraction for acute pain in children. Most of the review primary outcomes were assessed by only two or three small studies. We found limited data for adverse effects and other secondary outcomes. Future well-designed, large, high-quality trials may have an important impact on our confidence in the results.

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.

Study protocol for a randomised controlled trial of humanoid robot-based distraction for venipuncture pain in children

INTRODUCTION

Intravenous insertion (IVI) is a very common procedure in the emergency department (ED). IVI is often painful and stressful for both children and their families. Currently, distraction therapy is not used as a standard of care for IVI in North America. We propose that interaction with a humanoid robot may effectively distract children during IVI thereby reducing their pain and distress.

METHODS AND ANALYSIS

This randomised controlled superiority trial will be conducted in a Canadian paediatric ED. We plan to recruit 80 patients. Children will be eligible if they (1) are 6 to 11 years of age, (2) need an IVI, (3) are fully conscious and alert, (4) have sufficient knowledge of the English language to understand and complete the study assessments and (5) are accompanied by a legal guardian. Our primary objective is to compare patient-reported pain and distress with the use of distraction (via a humanoid robot) versus standard care in children. The primary outcomes will be (1) self-reported pain, as measured by the Faces Pain Scale-Revised and (2) observed distress, as measured by the Observational Scale of Behavioural Distress-Revised. Secondary outcomes will include (1) measuring parental anxiety, (2) examining the association between parental anxiety and child outcomes and (3) children's degree of engagement with the humanoid robot via the Intrinsic Motivation Inventory tool. First enrolment occurred in April 2017 and is ongoing.

ETHICS AND DISSEMINATION

This study has been approved by the Health Research Ethics Board (University of Alberta). Informed consent to participate will be obtained from all participants' parents/guardian, in conjunction with assent from the participant themselves. This study data will be submitted for publication regardless of results. Purchase of the robot was facilitated through a Stollery Children's Hospital Foundation donation. Recruitment costs are supported by the Women and Children's Health Research Institute.

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.

[Evaluation of pain in children of 2, 4 and 6 months after the application of non-pharmacological analgesia methods during vaccination]

INTRODUCTION

Young children perceive pain as much, or even more than adults, and the pain may have short- and long-term consequences. The literature describes the use of non-pharmacological interventions to alleviate pain during vaccination. The aim of this study was to assess 3such interventions for analgesia during vaccination: non-nutritive sucking (NNS), breastfeeding (BF), and administration of a 50% dextrose solution (D50W).

MATERIALS AND METHODS

A prospective, non-randomised cohort study was carried out on infants aged 2, 4 and 6 months that received 1, 2, or 3 vaccines, respectively, according to the routine immunisation schedule. There were 3treatments: NNS, BF, and 2mL of D50W combined with NNS. Pain was assessed using the LLANTO scale, and the duration of crying.

RESULTS

The study included 387 infants. The mean scores in the LLANTO scale at ages 2 and 6 months were significantly lower in breastfed infants compared to infants managed with NNS (P=.025 and P<.001, respectively), or infants given D50W (P=.025 and P=.001), and the difference was not statistically significant at age 4 months (P=.21 and P=.27). There were no significant differences between infants managed with NNS and D50W at 2, 4, and 6 months (P=.66, P=.93 and P=.45, respectively). The duration of crying was significantly lower at age 6 months in breastfeed infants compared to infants managed with NNS or D50W (P=.013 and P=.017). No breastfed child (n=129) experienced side effects.

CONCLUSIONS

In infants born to term with adequate weight for gestational age, breastfeeding reduces pain on the administration of 1 or 2 vaccines. When 3 vaccines are given, the reduction is minimal. Administration of D50W does not have any additional analgesic effect in infants compared to being held by a parent combined with NNS during vaccination. BF during vaccination is not associated with any side effects.

Procedural pain in children: a qualitative study of caregiver experiences and information needs

BACKGROUND

Children experience multiple painful procedures when being cared for in emergency departments (EDs). Unfortunately, evidence-based interventions to manage such pain and distress are under-utilized across EDs. Caregivers are uniquely positioned and invested to advocate for the adaptation of such evidence into practice. Our objective was to gather information from caregivers of children experiencing procedural pain in the ED to inform the development of a novel, caregiver-focused knowledge translation (KT) tool.

METHODS

The study design was qualitative description. Caregivers of children who underwent intravenous (IV) insertion or venipuncture in the pediatric ED at an urban tertiary care centre were interviewed. Thematic analysis was applied to the data. The TRanslating Emergency Knowledge for Kids (TREKK) Parent Advisory Group continuously informed this study, and provided input on interview guide development and piloting, data collection, analysis of the data, interpretation of the results, and development of next steps.

RESULTS

Interviews revealed four major themes: 1) source of healthcare information; 2) delivering healthcare information; 3) communication with caregivers; and 4) procedure-related anxiety and long-term effects. Caregivers most valued receiving information directly from their healthcare provider. They also expressed that healthcare providers should direct information about the procedure to their child and identified strategies to involve children in their care. Caregivers wanted to be empowered to ask informed questions of their healthcare providers. Finally, caregivers reported negative experiences with procedures for their children, occurring mainly at non-pediatric centres.

CONCLUSIONS

We have identified core information needs for caregivers whose children are experiencing IV insertion or venipuncture. These results will form the foundation for the development of a KT tool that may empower caregivers to actively participate in their child's healthcare.

Needle size for vaccination procedures in children and adolescents

BACKGROUND

This is an update of a Cochrane Review first published in 2015. The conclusions have not changed.Hypodermic needles of different sizes (gauges and lengths) can be used for vaccination procedures. The gauge (G) refers to the outside diameter of the needle tubing. The higher the gauge number, the smaller the diameter of the needle (e.g. a 23 G needle is 0.6 mm in diameter, whereas a 25 G needle is 0.5 mm in diameter). Many vaccines are recommended for injection into muscle (intramuscularly), although some are delivered subcutaneously (under the skin) and intradermally (into skin). Choosing an appropriate length and gauge of a needle may be important to ensure that a vaccine is delivered to the appropriate site and produces the maximum immune response while causing the least possible harm. Guidelines conflict regarding the sizes of needles that should be used for vaccinating children and adolescents.

OBJECTIVES

To assess the effects of using needles of different sizes for administering vaccines to children and adolescents on vaccine immunogenicity (the ability of the vaccine to elicit an immune response), procedural pain, and other reactogenicity events (adverse events following vaccine administration).

SEARCH METHODS

We updated our searches of CENTRAL, MEDLINE, Embase, and CINAHL to October 2017. We also searched proceedings of vaccine conferences and two trials registers.

SELECTION CRITERIA

Randomised controlled trials evaluating the effects of using hypodermic needles of any gauge or length to administer any type of vaccine to people aged from birth to 24 years.

DATA COLLECTION AND ANALYSIS

Three review authors independently extracted trial data and assessed the risk of bias. We contacted trial authors for additional information. We rated the quality of evidence using the GRADE system.

MAIN RESULTS

We included five trials involving 1350 participants in the original review. The updated review identified no new trials. The evidence from two small trials (one trial including infants and one including adolescents) was insufficient to allow any definitive statements to be made about the effects of the needles evaluated in the trials on vaccine immunogenicity and reactogenicity.The remaining three trials (1135 participants) contributed data to comparisons between 25 G 25 mm, 23 G 25 mm, and 25 G 16 mm needles. These trials included infants predominantly aged from two to six months undergoing intramuscular vaccination in the anterolateral thigh using the World Health Organization (WHO) injection technique (skin stretched flat, needle inserted at a 90° angle and up to the needle hub in healthy infants). The vaccines administered were combination vaccines containing diphtheria, tetanus, and whole-cell pertussis antigens (DTwP). In some trials, the vaccines also contained Haemophilus influenzae type b (DTwP-Hib) and hepatitis B (DTwP-Hib-Hep B) antigen components.Primary outcomesIncidence of vaccine-preventable diseases: No trials reported this outcome.Procedural pain and crying: Using a wider gauge 23 G 25 mm needle may slightly reduce procedural pain (low-quality evidence) and probably leads to a slight reduction in the duration of crying time immediately after vaccination (moderate-quality evidence) compared with a narrower gauge 25 G 25 mm needle (one trial, 320 participants). The effects are probably not large enough to be clinically relevant.Secondary outcomesImmune response: There is probably little or no difference in immune response, defined in terms of the proportion of seroprotected infants, between use of 25 G 25 mm, 23 G 25 mm, or 25 G 16 mm needles to administer a series of three doses of a DTwP-Hib vaccine at ages two, three, and four months (moderate-quality evidence, one trial, numbers of participants in analyses range from 309 to 402. The immune response to the pertussis antigen was not measured).Severe and non-severe local reactions: 25 mm needles (either 25 G or 23 G) probably lead to fewer severe and non-severe local reactions after DTwP-Hib vaccination compared with 25 G 16 mm needles (moderate-quality evidence, one trial, 447 to 458 participants in analyses). We estimate that one fewer infant will experience a severe local reaction (extensive redness and swelling) after the first vaccine dose for every 25 infants vaccinated with the longer rather than the shorter needle (number needed to treat for an additional beneficial outcome (NNTB) with a 25 G 25 mm needle: 25 (95% confidence interval (CI) 15 to 100); NNTB with a 23 G 25 mm needle: 25 (95% CI 17 to 100)). We estimate that one fewer infant will experience a non-severe local reaction (any redness, swelling, tenderness, or hardness (composite outcome)) at 24 hours after the first vaccine dose for every 5 or 6 infants vaccinated with a 25 mm rather than a 16 mm needle (NNTB with a 25 G 25 mm needle: 5 (95% CI 4 to 10); NNTB with a 23 G 25 mm needle: 6 (95% CI 4 to 13)). The results are similar after the second and third vaccine doses.Using a narrow gauge 25 G 25 mm needle may produce a small reduction in the incidence of local reactions after each dose of a DTwP vaccine compared with a wider gauge 23 G 25 mm needle, but the effect estimates are imprecise (low-quality evidence, two trials, 100 to 459 participants in analyses).Systemic reactions: The comparative effects of 23 G 25 mm, 25 G 25 mm, and 25 G 16 mm needles on the incidence of postvaccination fever and other systemic events such as drowsiness, loss of appetite, and vomiting are uncertain due to the very low quality of the evidence.

AUTHORS' CONCLUSIONS

Using 25 mm needles (either 23 G or 25 G) for intramuscular vaccination procedures in the anterolateral thigh of infants using the WHO injection technique probably reduces the occurrence of local reactions while achieving a comparable immune response to 25 G 16 mm needles. These findings are applicable to healthy infants aged two to six months receiving combination DTwP vaccines with a reactogenic whole-cell pertussis antigen component. These vaccines are predominantly used in low- and middle-income countries. The applicability of the findings to vaccines with acellular pertussis components and other vaccines with different reactogenicity profiles is uncertain.

Integrating Pediatric Hypnosis with Complementary Modalities: Clinical Perspectives on Personalized Treatment

While pediatric integrative medicine (PIM) emphasizes an "evidence-based practice using multiple therapeutic modalities"; paradoxically, literature reviews examining the prevalence and/or efficacy of such mind⁻body approaches often address PIM modalities separately. Such contributions are relevant, yet documentation of how to deliver combined complementary approaches in children and youth are scarce. Nevertheless, integrative practitioners in clinical practice routinely mix approaches to meet the individual needs of each patient. Best practices are flexible, and include blending and augmenting services within the same session, and/or connecting modalities sequentially for an incremental effect, and/or referring to outside resources for additional interventions. Resonating with integrative medicine's definition, this article's goal is to demonstrate paradigms that "bring together complementary approaches in a coordinated way within clinical practice" by linking clinical hypnosis, the trail-blazer modality in PIM's history, with mindfulness, biofeedback, acupuncture, and yoga. Following the consideration of the overlap of guided imagery with hypnosis and an abridged literature report, this clinical perspective considers the selection of modalities within a collaborative relationship with the child/teen and parents, emphasizing goodness-of-fit with patients' contexts, e.g., symptoms, resources, interests, goals, and developmental stage. Case vignettes illustrate practical strategies for mixing approaches.

Procedural Pain: Systematic Review of Parent Experiences and Information Needs

Parents wish to reduce their child's pain during medical procedures but may not know how to do so. We systematically reviewed the literature on parents' experiences and information needs related to managing their child's pain for common medical procedures. Of 2678 records retrieved through database searching, 5 were included. Three additional records were identified by scanning reference lists. Five studies were qualitative, and 3 were quantitative. Most took place in North America or Europe (n = 7) and described neonatal intensive care unit experiences (n = 5). Procedures included needle-related medical procedures (eg, venipuncture, phlebotomy, intravenous insertion), sutures, and wound repair and treatment, among others. Generally, parents desired being present during procedures, wanted to remain stoic for their child, and thought that information would be empowering and relieve stress but felt unsupported in taking an active role. Supporting and educating parents may empower them to lessen pain for their children while undergoing medical procedures.

Ghanaian nurses' knowledge of invasive procedural pain and its effect on children, parents and nurses

AIM

To explore Ghanaian nurses' knowledge of invasive procedural pain in children who are in hospital and to identify the effect of unrelieved pain on children, parents and nurses.

METHOD

An exploratory, descriptive and qualitative design was adopted. A purposive sampling technique was used and individual face-to-face, semi-structured interviews were conducted with 16 registered nurses from four children's units at a hospital in the Eastern Region of Ghana. Thematic and content analyses were performed.

FINDINGS

Four themes emerged: types of invasive procedure; pain expression; pain assessment; and effects of unrelieved pain. Participants had adequate knowledge of painful invasive procedures, however, they were not aware of the range of available validated pain assessment tools, using observations and body language instead to assess pain.

CONCLUSION

Ghanaian nurses require education on the use of validated rating scales to assess procedural pain in children. The inclusion of pain assessment and management in pre-registration curricula could improve knowledge.

Social Media for the Dissemination of Cochrane Child Health Evidence: Evaluation Study

Background

Health care providers value ready access to reliable synthesized information to support point-of-care decision making. Web-based communities, facilitated by the adoption of social media tools such as Facebook, Twitter, and YouTube, are increasingly being used for knowledge dissemination, bridging the gap between knowledge generation and synthesis and knowledge implementation.

Objective

Our objective was to implement and evaluate a structured social media strategy, using multiple platforms, to disseminate Cochrane Child Health evidence to health care providers caring for children.

Methods

Our social media strategy had three components: daily “tweets” using the Cochrane Child Health Twitter account, weekly WordPress blog posts, and a monthly journal club on Twitter (“tweet chat”). Each tweet, blog, and journal club shared Cochrane evidence on a child health topic. We evaluated the strategy through (1) Twitter and blog site analytics, (2) traceable link (Bitly) statistics, (3) Altmetric.com scores for promoted evidence, and (4) participant feedback. We also tracked the resources required to write the blog, tweet content, and manage the strategy.

Results

The 22-week social media strategy ran between November 2014 and April 2015. We created 25 blog posts, sent 585 tweets, and hosted 3 tweet chats. Monthly blog visits and views and Twitter account followers increased over time. During the study period, the blog received 2555 visitors and 3967 page views from a geographically diverse audience of health care providers, academics, and health care organizations. In total, 183 traceable Bitly links received 3463 clicks, and the Twitter account gained 469 new followers. The most visited and viewed blog posts included gastrointestinal topics (lactose avoidance), research on respiratory conditions (honey for cough and treatments for asthma), and maternal newborn care (skin-to-skin contact). On Twitter, popular topics were related to public health (vaccination) and pain management. We collected Altmetric.com scores for 61 studies promoted during the study period and recorded an average increase of 11 points. Research staff (n=3) contributed approximately 433 hours to promotion activities and planning (6.5 hours each per week) to implement the social media strategy, and study investigators reviewed all content (blog posts and tweets).

Conclusions

This study provides empirical evidence on the use of a coordinated social media strategy for the dissemination of evidence to professionals providing health services to children and youth. The results and lessons learned from our study provide guidance for future knowledge dissemination activities using social media tools.

Parent experiences and information needs relating to procedural pain in children: a systematic review protocol

BACKGROUND

There exist many evidence-based interventions available to manage procedural pain in children and neonates, yet they are severely underutilized. Parents play an important role in the management of their child's pain; however, many do not possess adequate knowledge of how to effectively do so. The purpose of the planned study is to systematically review and synthesize current knowledge of the experiences and information needs of parents with regard to the management of their child's pain and distress related to medical procedures in the emergency department.

METHODS

We will conduct a systematic review using rigorous methods and reporting based on the PRISMA statement. We will conduct a comprehensive search of literature published between 2000 and 2016 reporting on parents' experiences and information needs with regard to helping their child manage procedural pain and distress. Ovid MEDLINE, Ovid PsycINFO, CINAHL, and PubMed will be searched. We will also search reference lists of key studies and gray literature sources. Two reviewers will screen the articles following inclusion criteria defined a priori. One reviewer will then extract the data from each article following a data extraction form developed by the study team. The second reviewer will check the data extraction for accuracy and completeness. Any disagreements with regard to study inclusion or data extraction will be resolved via discussion. Data from qualitative studies will be summarized thematically, while those from quantitative studies will be summarized narratively. The second reviewer will confirm the overarching themes resulting from the qualitative and quantitative data syntheses. The Critical Appraisal Skills Programme Qualitative Research Checklist and the Quality Assessment Tool for Quantitative Studies will be used to assess the quality of the evidence from each included study.

DISCUSSION

To our knowledge, no published review exists that comprehensively reports on the experiences and information needs of parents related to the management of their child's procedural pain and distress. A systematic review of parents' experiences and information needs will help to inform strategies to empower them with the knowledge necessary to ensure their child's comfort during a painful procedure.

Clinical Hypnosis, an Effective Mind-Body Modality for Adolescents with Behavioral and Physical Complaints

Mind-body medicine is a system of health practices that includes meditation/relaxation training, guided imagery, hypnosis, biofeedback, yoga, art/music therapy, prayer, t'ai chi, and psychological therapies such as cognitive behavioral therapy. Clinical hypnosis is an important mind-body tool that serves as an adjunct to conventional medical care for the adolescent patient. Clinical hypnosis specifically uses self-directed therapeutic suggestions to cultivate the imagination and facilitate the mind-body connection, leading to positive emotional and physical well-being. There are many similarities between clinical hypnosis and other mind-body/self-regulatory modalities such as visual imagery, mindfulness meditation, yoga, and biofeedback that incorporate experiential learning and mechanisms for change. They may be viewed as subtypes of the hypnotic experience and share the common experience of trance as the entrée into self-empowered change in physiologic and psychological states. Clinical hypnosis can be used by health care providers to teach adolescents coping skills to deal with a wide variety of conditions such as chronic headaches, recurrent abdominal pain, anxiety, depression, grief and bereavement, phobias, anger, family stressors, sleep disorders, or enuresis. Clinical vignettes are given to help illustrate the effectiveness of hypnosis in adolescents.

Scientometric analysis of psychological interventions based upon the use of Hypnosis

Hypnosis is a therapeutic technique that has developed for centuries, and every time with greater clinical and scientific weight. Currently, hypnosis constitutes a solid support method for treatments against chronic pain and for emotion control under situations that generate fear and anxiety -such as surgery or other type of phobias-, so it is presented as an alternative to the use of medicine/drugs by health specialists. On the other hand within the field of behavioral sciences, apart from controlling fear and anxiety responses, hypnosis serves as support to the various cognitive behavioral techniques by facilitating their assimilation and development. This work presents a scientometric study of the research done on hypnosis over the last fifteen years, from publications -in Spanish and English- in specialized journals, indexed in SCOPUS (a specialized international bibliometric database). The contemporary applications of hypnosis are presented and critically discussed; as well as the fields in which its application has proven successful; its limitations; the research networks generated within the time of the study; plus, probable projections for future research are also mentioned. 

Hypnosis Training and Education: Experiences with a Norwegian One-Year Education Course in Clinical Hypnosis for Children and Adolescents

Although the efficacy of clinical hypnosis is well documented, its implementation in clinical practice is far from completed and there are few reports of systematic, professional training. This article gives a historical overview and description of a 1-year training program in clinical hypnosis which started in Norway in 2008 and has been held yearly since then. We describe the present education course with respect to aims, conceptual framework, structure, target groups, teaching themes, and experiences. The following factors have been considered of importance for the success of this program: The extent and duration of the course, the focus on demonstrations, experiential skill-building and exercises, and that the education is rooted in acknowledged clinical, academic, and educational environments. The participants' evaluations tell stories of mastery and positive experiences with hypnosis as a therapeutic tool in their clinical practice. However, many struggle to understand the various concepts of hypnosis, trance, and suggestions. Some find it hard to get started and challenging to integrate hypnosis in their clinical practice. Finally, some report scarce opportunities to apply their newly acquired skills at their work places and limited support by their leaders. The development of systematic, professional training programs as described in this article may be of importance for further implementation. However, this will also require that clinicians and leaders in universities and professional environments, and policymakers at higher levels, recognize clinical hypnosis as a valid and efficient choice of treatment. This must be reflected in dedicated efforts to ensure successful implementation in practice.

A mixed-method study of pain management practice in a UK children's hospital: identification of barriers and developing strategies to maintain effective in-patient paediatric pain management

AIM

To assess Acute Pain Service and paediatric pain management efficacy in a UK specialist paediatric hospital to inform wider recommendations for future sustainability.

BACKGROUND

UK paediatric acute pain services vary. Although comprehensive pain management guidelines exist, consensus on the best model of care is lacking. Worldwide, medical and pharmacological advances and rapid patient turnover have increased the challenges of managing hospitalized children's pain. Simultaneously nurses, who deliver the bulk of pain management, have experienced reduction in skill mix and training opportunities. Specialist Acute Pain Services have evolved to meet these demands; their overall efficacy is unknown.

DESIGN

This mixed-methods study explores pain management practice at a UK paediatric hospital to assess current efficacy and future sustainability.

METHOD

A 2013 case note review of all Acute Pain Services referrals over 14 days were compared with an interval sample of concurrent non-referred inpatient children; seven semi-structured interviews were conducted with a range of clinical staff.

RESULTS

Twenty-two referrals of 15 children were made; 15 comparison children were identified. All 30 children (100%) were appropriately referred/non-referred. Acute Pain Services cases experienced higher pain levels, were more likely to have long term conditions, longer hospital stay and repeat admissions. Three key themes emerged through interview analysis: 'addressing pain', 'changing contexts' 'pain as an "expert" skill'. Increased specialization, reduced clarity between different pain modalities and decreased training opportunities had resulted in potentially unsustainable APS dependence.

Needle size for vaccination procedures in children and adolescents

BACKGROUND

Hypodermic needles of different sizes (gauges and lengths) can be used for vaccination procedures. The gauge (G) refers to the outside diameter of the needle tubing. The higher the gauge number, the smaller diameter of the needle (eg a 25 G needle is 0.5 mm in diameter and is narrower than a 23 G needle (0.6 mm)). Many vaccines are recommended for injection into muscle (intramuscularly), although some are delivered subcutaneously (under the skin) and intradermally (into skin). Choosing an appropriate length and gauge of a needle may be important to ensure that a vaccine is delivered to the appropriate site and produces the maximum immune response while causing the least possible harm. There are some conflicting guidelines regarding the lengths and gauges of needles that should be used for vaccination procedures in children and adolescents.

OBJECTIVES

To assess the effects of using needles of different lengths and gauges for administering vaccines to children and adolescents on vaccine immunogenicity (the ability of the vaccine to elicit an immune response), procedural pain, and other reactogenicity events (adverse events following vaccine administration).

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2014, Issue 10), MEDLINE and MEDLINE in Progress via Ovid (1947 to November 2014), EMBASE via Ovid (1974 to November 2014), and CINAHL via EBSCOhost (1982 to November 2014). We also searched reference lists of articles and textbooks, the proceedings of vaccine conferences, and three clinical trial registers.

SELECTION CRITERIA

Randomised controlled trials evaluating the effects of using hypodermic needles of any gauge or length to administer any type of vaccine to people aged from birth to 24 years.

DATA COLLECTION AND ANALYSIS

Three review authors independently extracted trial data and assessed the risk of bias. We contacted trial authors for additional information. We rated the quality of evidence using the GRADE system.

MAIN RESULTS

We included five trials involving 1350 participants. Data for the primary review outcomes were either absent (for the incidence of vaccine-preventable diseases) or limited (for procedural pain and crying). The available evidence was compromised by the use of surrogate immunogenicity outcomes, incomplete blinding of outcome assessors, and imprecision for some outcomes. The evidence from two small trials was insufficient to allow any confident statements to be made about the effects of the needles evaluated in the trials on vaccine immunogenicity and reactogenicity.The remaining three trials (1135 participants) contributed data to comparisons between 25 G 25 mm, 23 G 25 mm, and 25 G 16 mm needles. These trials involved infants predominantly aged two to six months undergoing intramuscular vaccination in the anterolateral thigh using the World Health Organization (WHO) injection technique (skin stretched flat, needle inserted at a 90° angle and up to the needle hub in healthy infants). The vaccines administered were combination vaccines containing diphtheria, tetanus, and whole-cell pertussis antigens (DTwP). In some trials, the vaccines also contained Haemophilus influenzae type b (DTwP-Hib) and hepatitis B (DTwP-Hib-HepB) antigen components.We found moderate quality evidence from one trial that there is probably little or no difference in immune response, defined in terms of the proportion of seroprotected infants, between using 25 G 25 mm, 23 G 25 mm, or 25 G 16 mm needles to administer a series of three doses of a DTwP-Hib vaccine at ages two, three, and four months (numbers of participants in analyses range from 309 to 402. Immune response to pertussis antigen not measured).25 mm needles (either 23 G or 25 G) probably lead to fewer severe local reactions (extensive redness and swelling) and fewer non-severe local reactions (any redness, swelling, tenderness or hardness (composite outcome)) after DTwP-Hib vaccination compared with 25 G 16 mm needles. We estimate that one fewer infant will experience a severe local reaction after the first vaccine dose for every 25 infants vaccinated with the longer rather than the shorter needle (number needed to treat (NNT) 25 (95% confidence interval (CI) 15 to 100)). We estimate that one fewer infant will experience a non-severe local reaction at 24 hours after the first, second, and third vaccine doses for every five to eight infants vaccinated with the longer rather than the shorter needle (NNTs range from 5 (95% CI 4 to 10) to 8 (95% CI 5 to 34)) (moderate quality evidence, one trial for first and second doses, two trials for third dose, numbers of participants in analyses range from 413 to 528).Using a wider gauge needle (23 G 25 mm) may slightly reduce procedural pain (low quality evidence) and probably leads to a slight reduction in the duration of crying time immediately after vaccination (moderate quality evidence) compared with a narrower gauge (25 G 25 mm) needle (one trial, 320 participants). The effects are probably not large enough to be of any clinical relevance. The 25 G 25 mm needle may produce a small reduction in the incidence of local reactions after each dose of a DTwP vaccine compared with the 23 G 25 mm needle, but the effect estimates are imprecise (low quality evidence, two trials, numbers of participants in analyses range from 100 to 459).The comparative effects of 23 G 25 mm, 25 G 25 mm, and 25 G 16 mm needles on the incidence of post-vaccination fever, persistent inconsolable crying, and other systemic events such as drowsiness, loss of appetite, and vomiting are uncertain due to the very low quality of the evidence.

AUTHORS' CONCLUSIONS

Using 25 mm needles (either 23 G or 25 G) for intramuscular vaccination procedures in the anterolateral thigh of infants using the WHO injection technique probably reduces the occurrence of local reactions while achieving a comparable immune response to 25 G 16 mm needles. These findings are applicable to healthy infants aged two to six months receiving combination DTwP vaccines with a reactogenic whole-cell pertussis antigen component. These vaccines are predominantly used in developing countries. The applicability of the findings to vaccines with acellular pertussis components and other vaccines with different reactogenicity profiles is uncertain.

Effect of distraction on children's pain during intravenous catheter insertion

PURPOSE

This study examined the effect of pressing a soft ball during intravenous catheter insertion (IVCI) on the intensity of pain in children ages 4-6 years.

DESIGN AND METHODS

In this quasi-experimental study, children in the intervention group were asked to press a soft ball with the opposite hand during IVCI and to immediately mark the Wong-Baker FACES Pain Rating Scale.

RESULTS

There was a significant difference in the intensity of pain between the control group (n = 30) and the intervention group (n = 30; p =.012).

PRACTICE IMPLICATIONS

Pressing a soft ball during IVCI may be an easily accessed, inexpensive, and effective technique to control or reduce pain in young children.
