Assessment of acute pain in children: development of evidence-based guidelines

Comparative efficacy of pharmacological and non-pharmacological interventions for mitigating pain and anxiety associated with venipuncture: a randomised controlled trial

BACKGROUND

Venipuncture is one of the most commonly performed medical procedures in paediatric care, but it can also be one of the most painful and distressing experiences for patients. Finding effective strategies to manage pain and fear associated with venipuncture is crucial for improving the paediatric patient experience and promoting positive health outcomes. This study aimed to evaluate the efficacy of a combined approach using a topical analgesic cream (TKTX cream) and a distraction technique (Trace Image and Colouring for Kids-Book, TICK-B) in reducing pain intensity and fear levels in children undergoing venipuncture procedures.

METHODS

We conducted this randomised controlled trial among 176 children aged 6-12 years undergoing venipuncture. Participants were randomly assigned to four groups: TICK-B, TKTX cream, TICK-B+TKTX cream and a control group. Pain and fear were measured using the Wong-Baker FACES Pain Rating Scale and Children's Fear Scale. The study was carried out from 20 February 2024 to 1 June 2024 at the emergency unit of Heevi paediatric teaching hospital in the Kurdistan region of Iraq. In the intervention groups, TICK-B was applied for 2-3 min before needle insertion, and TKTX cream was applied 20 min before the venipuncture procedure. All outcome measures were evaluated 2-3 min after the completion of the venipuncture procedure.

RESULTS

The combined TICK-B (colouring book) and TKTX cream (topical anaesthetic) intervention was the most effective in reducing both pain intensity (mean score 2.80 vs 7.24 in the control, p<0.001) and fear levels (mean score 0.93 vs 2.83 in the control, p<0.001) during and after venipuncture procedures compared with individual interventions and control.

CONCLUSIONS

The combined TICK-B distraction and TKTX cream topical anaesthetic intervention was the most effective in reducing pain intensity and fear during and after venipuncture in children, providing a practical strategy for healthcare providers to optimise needle procedure management.

Pain assessment tools for use in infants: a meta-review

BACKGROUND

Identifying pain in infants is challenging due to their inability to self-report pain, therefore the availability of valid and reliable means of assessing pain is critical.

OBJECTIVE

This meta-review sought to identify evidence that could guide the selection of appropriate tools in this vulnerable population.

METHODS

We searched Scopus, Medline, Embase, CINAHL, MIDRIS, EMCare and Google Scholar for eligible systematic reviews. Eligible reviews documented psychometric properties of available observational tools used to assess pain in infants.

RESULTS

A total of 516 reviews were identified of which 11 met our inclusion criteria. We identified 36 pain assessment tools (evaluated in 11 reviews) of which seven were reported in at least three reviews. The level of evidence reported on the psychometric properties of pain assessment tools varied widely ranging from low to good reliability and validity, whilst there are limited data on usability and clinical utility.

CONCLUSIONS

Currently, no observer administered pain assessment tool can be recommended as the gold standard due to limited availability and quality of the evidence that supports their validity, reliability and clinical utility. This meta-review attempts to collate the available evidence to assist clinicians to decide on what is the most appropriate tool to use in their clinical practice setting. It is important that researchers adopt a standard approach to evaluating the psychometric properties of pain assessment tools and evaluations of the clinical utility in order that the highest level of evidence can be used to guide tool selection.

The evidence supporting the association between the use of pain scales and outcomes in hospitalized children: A systematic review

BACKGROUND

Systematic use of pain intensity scales is considered a prerequisite for treatment of pain in hospitalized children, but already a decade ago, attention was called to the lack of robust evidence supporting the presumed positive association between their use and desired outcomes.

OBJECTIVES

To re-evaluate the evidence supporting the association between the use of pain scales and patient and process outcomes in hospitalized children.

DESIGN

Systematic literature review.

DATA SOURCES

The online databases PubMed and Cumulative Index of Nursing and Allied Health Literature (CINAHL) were searched from inception to April 15, 2020.

REVIEW METHODS

We performed single screening of all records followed by duplicate screening of full texts of interest with a disagreement procedure in place. Studies where the authors evaluated outcomes from the use of self-report or behavioral-based pain scales in children 0-18 years in a hospital setting were included. Emergency care settings were excluded.

RESULTS

In a majority of the 32 included studies, complex interventions that included one or more pain scales were evaluated. Process outcomes (e.g., documentation) were most frequently studied. Interventions were commonly associated with improved documentation of pain assessment, while the effect on pain management documentation was inconsistent. However, improvements in process outcomes did not necessarily result in better patient outcomes. In regard to patient outcomes (e.g., pain intensity, side effects, or satisfaction with treatment), some authors reported reduced pain intensity on group level, but the effect on other functional outcomes, child and parent satisfaction, and aspects of safety were inconsistent. Methodological issues, e.g., weak study designs and small samples, biased the results, and it was not possible to determine how pain scales contributed to the overall effects since they were studied as part of complex interventions.

CONCLUSIONS

Although both a theoretically founded understanding of pain and clinical experience suggest that the use of pain scales will make a difference for hospitalized children with pain, there is still limited evidence to support this notion. As pain scales have been almost exclusively studied as an aspect of complex interventions, research that determines the active ingredient(s) in a complex intervention and their joint and individual effects on outcomes that are meaningful for the child (for example reduced pain intensity or improved function) are urgently needed.

Experience of Registered Nurses of Postoperative Pain Assessment Using Objective Measures among Children at Effia Nkwanta Regional Hospital in Ghana

Introduction: People undergoing surgical operations experience some level of pain. Assessing pain intensity is one of the duties of the nurse and it involves subjective measures (self-report), and objective measures (behavioural and physiological). It has been observed by the researcher that nurses in clinical practice do not assess pain before management more so among children. Also, there is limited research in the area of pain assessment in children who cannot communicate. This study aimed to describe the experiences of registered nurses in assessing postoperative pain among children (0-3 years) using objective measures.

Methods: Descriptive phenomenology was the chosen design. Maximum variation sampling was used to recruit nine registered nurses with experience in nursing children after surgery at Effia Nkwanta Regional Hospital (ENRH) in Ghana. The researchers conducted audio-recorded in-depth interviews, transcribed verbatim and qualitatively analyzed following Colaizzi’s approach to descriptive phenomenology analysis.

Results: The study revealed that the nurses have more experience with using behavioural measures with limited experience with the use of physiological measures. The behavioural measures mostly reported from their experience were changes in facial expression and unusual crying of the child. In general, the nurses do not formally use consistent approaches to assess pain among children.

Conclusion: Given these results, opportunities should be made available for nurses to enhance their skills and utilize evidence-based approaches to formally assess pain among post-operative children.

Topical Review: State of the Field of Child Self-Report of Acute Pain

OBJECTIVE

Children experience acute pain with routine and emergent healthcare, and untreated pain can lead to a range of repercussions. Assessment is vital to diagnosing and treating acute pain. Given the internal nature of pain, self-report is predominant. This topical review reflects on the state of the field of pediatric acute pain self-report, and proposes a framework for acute pain assessment via self-report.

METHOD

We examine self-report of acute pain in preschool-age children through adolescents, and we detail a three-step process to optimize acute pain assessment.

RESULTS

The first step is to decide between a pain screening or assessment. Several 0-10 self-report scales are available for pain screenings. Assessment requires specification of the goals and domains to target. Core criteria, common features, modulating factors, and consequences of acute pain provide a framework for a comprehensive pain assessment. Whereas there are some measures available to assess aspects of these domains, there are considerable gaps. Last, it is important to integrate the data to guide clinical care of acute pain.

CONCLUSIONS

Self-report of acute pain is dominated by single-item intensity scales, which are useful for pain screening but inadequate for pain assessment. We propose a three-step approach to acute pain assessment in children. However, there is a need for measure development for a comprehensive evaluation of the core criteria, common features, modulating factors, and consequences of pediatric acute pain. In addition, there is limited guidance in merging data found in multifaceted evaluations of pediatric acute pain.

The Society for Pediatric Anesthesia recommendations for the use of opioids in children during the perioperative period

Opioids have long held a prominent role in the management of perioperative pain in adults and children. Published reports concerning the appropriate, and inappropriate, use of these medications in pediatric patients have appeared in various publications over the last 50 years. For this document, the Society for Pediatric Anesthesia appointed a taskforce to evaluate the available literature and formulate recommendations with respect to the most salient aspects of perioperative opioid administration in children. The recommendations are graded based on the strength of the available evidence, with consensus of the experts applied for those issues where evidence is not available. The goal of the recommendations was to address the most important issues concerning opioid administration to children after surgery, including appropriate assessment of pain, monitoring of patients on opioid therapy, opioid dosing considerations, side effects of opioid treatment, strategies for opioid delivery, and assessment of analgesic efficacy. Regular updates are planned with a re-release of guidelines every 2 years.

A comparison of intraoperative haemostatic techniques during tonsillectomy: Suture vs electrocautery-A study to assess postoperative pain scores and duration to resumption of normal diet

OBJECTIVES

To assess postoperative pain and pattern of recovery to normal diet in children who underwent tonsillectomy.

METHODS

Cold steel tonsillectomy (or adenotonsillectomy) was performed in 61 children. Haemostasis was attained with sutures in Group 1 (n = 30, 8 tonsillectomy and 22 adenotonsillectomy), and electrocautery in Group 2 (n = 31, 6 tonsillectomy and 25 adenotonsillectomy). Information obtained included postoperative pain scores and the number of postoperative days taken to resume normal diet. The pain score was evaluated with the Wong-Baker FACES^® Pain Rating Scale (WBFS).

RESULTS

Pain values in Group 1 (haemostasis with sutures) were significantly lower than those in Group 2 (haemostasis with cauterisation) from the 6th hour to the 7th postoperative day (P < .05). For both liquid and solid food, Group 1 returned to normal diet earlier, compared to Group 2 (P < .05). When comparing patients undergoing tonsillectomy vs adenotonsillectomy, resumption of normal diet was achieved later in the adenotonsillectomy patients (P < .05). In terms of postoperative bleeding, there were 2 significant events in Group 2 (electrocautery group), occurring on the 1st (severe) and 10th day (slight) in 2 children (6.5%). There were no postoperative bleeding events in Group 1.

CONCLUSION

Our results showed that suture haemostatis causes less pain and faster resumption of normal diet compared to electrocautery. In view of this, we recommend the use of sutures for achieving intraoperative haemostasis in paediatric patients.

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.

Eight principles for patient-centred and family-centred care for newborns in the neonatal intensive care unit

Despite the recent improvements in perinatal medical care leading to an increase in survival rates, adverse neurodevelopmental outcomes occur more frequently in preterm and/or high-risk infants. Medical risk factors for neurodevelopmental delays like male gender or intrauterine growth restriction and family sociocultural characteristics have been identified. Significant data have provided evidence of the detrimental impact of overhelming environmental sensory inputs, such as pain and stress, on the developing human brain and strategies aimed at preventing this impact. These strategies, such as free parental access or sleep protection, could be considered 'principles of care'. Implementation of these principles do not require additional research due to the body of evidence. We review the scientific evidence for these principles here.

Acute pain assessment tools: let us move beyond simple pain ratings

PURPOSE OF REVIEW

This review highlights challenges and current trends in tools used to assess acute pain across the lifespan.

RECENT FINDINGS

A plethora of similar assessment tools exist for acute pain, most focused on self-report of pain intensity. Attempts to improve the frequency and visibility of pain assessment by prompting pain as 'the fifth vital sign' resulted in unintended consequences, creating a pressing need for a conceptual shift to multidimensional assessment of acute pain.

SUMMARY

Valid and pragmatic assessment of pain is essential for effective pain management. Unidimensional scales that capture self-reported pain intensity ratings undervalue to the complexity of the pain experience. Pain is a biopsychosocial experience and assessment is a complex social transaction and an exchange of the meaning of pain that demands a more comprehensive approach.

Investigating the effect of Eye Movement Desensitization and Reprocessing (EMDR) on postoperative pain intensity in adolescents undergoing surgery: a randomized controlled trial

AIM

To investigate the efficacy of Eye Movement Desensitization and Reprocessing for postoperative pain management in adolescents.

BACKGROUND

Eye Movement Desensitization and Reprocessing is an inexpensive, non-pharmacological intervention that has successfully been used to treat chronic pain. It holds promise in the treatment of acute, postsurgical pain based on its purported effects on the brain and nervous system.

DESIGN

A randomized controlled trial was used.

METHODS

Fifty-six adolescent surgical patients aged between 12-18 years were allocated to gender-balanced Eye Movement Desensitization and Reprocessing (treatment) or non-Eye Movement Desensitization and Reprocessing (control) groups. Pain was measured using the Wong-Baker FACES(®) Pain Rating Scale (WBFS) before and after the intervention (or non-intervention for the control group).

FINDINGS

A Wilcoxon signed-rank test demonstrated that the Eye Movement Desensitization and Reprocessing group experienced a significant reduction in pain intensity after treatment intervention, whereas the control group did not. Additionally, a Mann-Whitney U-test showed that, while there was no significant difference between the two groups at time 1, there was a significant difference in pain intensity between the two groups at time 2, with the Eye Movement Desensitization and Reprocessing group experiencing lower levels of pain.

CONCLUSION

These results suggest that Eye Movement Desensitization and Reprocessing may be an effective treatment modality for postoperative pain.

Recent Advances in Pediatric Use of Oral Paracetamol in Fever and Pain Management

Paracetamol is a common analgesic and antipyretic drug for management of fever and mild-to-moderate pain in infants and children, and it is considered as first-line therapy for the treatment of both according to international guidelines and recommendations. The mechanism of action of paracetamol is complex and multifactorial, and several aspects of the pharmacology impact its clinical use, especially in the selection of the correct analgesic and antipyretic dose. A systematic literature search was performed by following procedures for transparent reporting of systematic reviews and meta-analyses. To maximize efficacy and avoid delays in effect, use of the appropriate dose of paracetamol is paramount. Older clinical studies using paracetamol at subtherapeutic doses of ≤10 mg/kg generally show that it is less effective than non-steroidal anti-inflammatory drugs (NSAIDs). However, recent evidence shows that when used at dose of 15 mg/kg for fever and pain management, paracetamol is significantly more effective than placebo, and at least as effective as NSAIDs. Paracetamol 15 mg/kg has a tolerability profile similar to that of placebo and NSAIDs such as ibuprofen and ketoprofen used for short-term treatment of fever. However, when used at repetitive doses for consecutive days, paracetamol shows lower risk of adverse events compared to NSAIDs. Also, unlike NSAIDs, paracetamol is indicated for use in children of all ages. Overall, clinical evidence qualifies paracetamol 15 mg/kg a safe and effective option for treatment of pain and fever in children.

Randomized comparison of a silicone tape and a paper tape for gentleness in healthy children

PURPOSE

To compare the relative gentleness of a silicone tape to a paper tape in healthy infants and children.

DESIGN

A randomized, grader-blinded, comparative study.

SUBJECTS AND SETTING

The sample group comprised 24 healthy infants and children 9.1 to 46.7 months of age (mean ± SEM, 34.0 ± 2.21). The study was conducted at a dermatological research facility (cyberDERM, Inc) located in Broomall, Pennsylvania. All volunteers were recruited from the surrounding community.

METHODS

Tapes measuring 1 × 1.5 inches were randomly applied to the left and right intrascapular regions of the upper back. Tapes were removed in a standardized fashion after 24 hours. The primary study outcome, gentleness, was based on visual assessments of skin damage, discomfort, and quantification of keratin removal. Four-point scales were used to assess skin damage, and a 10-point Faces, Legs, Activity, Cry, and Consolability instrument was used to assess discomfort. Secondary assessments included hair removal, tape edge-lift assessments, and parent preference for either tape.

RESULTS

There was a significantly lower mean ± SEM erythema response for the silicone tape (0.93 ± 0.14 vs 1.35 ± 0.11, P = .0129) than for the paper tape. No measurable epidermal stripping occurred with the silicone tape compared to a mean ± SEM response of 0.29 ± 0.11 for the paper tape (P = .0039). Discomfort was significantly lower (P = .0002) for the silicone tape as compared to the paper tape (Faces, Legs, Activity, Cry, and Consolability score mean difference from baseline 0.5 vs 3.3, P = .0002). Keratin removal was significantly less with the silicone as compared to paper tape (8.7 ± 0.5 μg/mL vs 15.2 ± 1.3 μg/mL, P < .0001). Few hairs were removed with either tape. There was significantly less (P < .0001) edge-lift with the paper tape than the silicone tape; no statistically significant differences in parent preferences for silicone versus paper tapes were measured (P = .3359).

CONCLUSIONS

Gentleness assessments favored the silicone tape compared to a paper tape and warrant further clinical investigation in the neonatal intensive care unit.

Pain management in newborns

As a standard of care for preterm/term newborns effective pain management may improve their clinical and neurodevelopmental outcomes. Neonatal pain is assessed using context-specific, validated, and objective pain methods, despite the limitations of currently available tools. Therapeutic approaches reducing invasive procedures and using pharmacologic, behavioral, or environmental measures are used to manage neonatal pain. Nonpharmacologic approaches like kangaroo care, facilitated tucking, non-nutritive sucking, sucrose, and others can be used for procedural pain or adjunctive therapy. Local/topical anesthetics, opioids, NSAIDs/acetaminophen and other sedative/anesthetic agents can be incorporated into NICU protocols for managing moderate/severe pain or distress in all newborns.

A pain research agenda for the 21st century

Chronic pain represents an immense clinical problem. With tens of millions of people in the United States alone suffering from the burden of debilitating chronic pain, there is a moral obligation to reduce this burden by improving the understanding of pain and treatment mechanisms, developing new therapies, optimizing and testing existing therapies, and improving access to evidence-based pain care. Here, we present a goal-oriented research agenda describing the American Pain Society's vision for pain research aimed at tackling the most pressing issues in the field.

PERSPECTIVE

This article presents the American Pain Society's view of some of the most important research questions that need to be addressed to advance pain science and to improve care of patients with chronic pain.

The postoperative management of pain from intracranial surgery in pediatric neurosurgical patients

Pain following intracranial surgery has historically been undertreated because of the concern that opioids, the analgesics most commonly used to treat moderate-to-severe pain, will interfere with the neurologic examination and adversely affect postoperative outcome. Over the past decade, accumulating evidence, primarily in adult patients, has revealed that moderate-to-severe pain is common in neurosurgical patients following surgery. Using the neurophysiology of pain as a blueprint, we have highlighted some of the drugs and drug families used in multimodal pain management. This analgesic method minimizes opioid-induced adverse side effects by maximizing pain control with smaller doses of opioids supplemented with neural blockade and nonopioid analgesics, such nonsteroidal antiinflammatory drugs, local anesthetics, corticosteroids, N-methyl-D-aspartate (NMDA) antagonists, α2 -adrenergic agonists, and/or anticonvulsants (gabapentin and pregabalin).

Pediatric clinical practice guidelines for acute procedural pain: a systematic review

BACKGROUND

Procedural pain assessment and management have been extensively studied through multiple research studies over the past decade. Results of this research have been included in numerous pediatric pain practice guidelines.

OBJECTIVE

To systematically review the quality of existing practice guidelines for acute procedural pain in children and provide recommendations for their use.

METHODS

A systematic search was conducted on Medline, Embase, CINAHL, PsycINFO, and Scopus from 2000 to July 2013. A gray literature search was also conducted through the Translating Research Into Practice database, Guidelines International Network database, and National Guideline Clearinghouse. Four reviewers rated relevant guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE) II Instrument. Screening of guidelines, assessment of methodological quality, and data abstraction were conducted by 2 pairs of raters. Disagreements in overall assessments were resolved through consensus.

RESULTS

Eighteen guidelines from 4930 retrieved abstracts were included in this study. Based on the AGREE II domains, the guidelines generally scored high in the scope and purpose and clarity of presentation areas. Information on the rigor of guideline development, applicability, and editorial independence were specified infrequently. Four of the 18 guidelines provided tools to help clinicians apply the recommendations in practice settings; 5 were recommended for use in clinical settings, and the remaining 13 were recommended for use with modification.

CONCLUSIONS

Despite the increasing availability of clinical practice guidelines for procedural pain in children, the majority are of average quality. More transparency and comprehensive reporting are needed for the guideline development process.

Pain assessment in children undergoing venipuncture: the Wong-Baker faces scale versus skin conductance fluctuations

The aim of this study was to evaluate the efficacy of the subjective Wong–Baker faces pain rating scale (WBFS) and of the objective skin conductance fluctuation (SCF) test in assessing pain in children undergoing venipuncture. One-hundred and fifty children (aged 5–16 years) entered the study. All underwent venipuncture at the antecubital fossa to collect blood specimens for routine testing in the same environmental conditions. After venipuncture, the children indicated their pain intensity using the WBFS, whereas the number of SCFs was recorded before, during and after venipuncture. So, pain level was measured in each child with WBFS and SCF. We found that the level of WBFS-assessed pain was lower in all children, particularly those above 8 years of age, than SCF-assessed pain (p < 0.0001). Moreover, the number of SCFs was significantly higher during venipuncture than before or after venipuncture (p < 0.0001). At multivariate regression analysis, age and previous experience of venipuncture influenced the WBFS (β = −1.81, p < 0.001, and β = −0.86, p < 0.001, respectively) but not SCFs. In conclusion, although both procedures can be useful for research and clinical practice, our findings show that WBFS was affected by age and previous venipuncture, whereas SCF produced uniform data. If verified in other studies, our results should be taken into account when using these tools to evaluate pain in children.

Procedural pain and anxiety in paediatric patients in a Mexican emergency department

AIM

This article is a report of a study carried out to investigate the procedures that are likely to induce pain and anxiety in children in a Mexican emergency department.

BACKGROUND

In emergency rooms, children often experience unpredictable diagnostic and therapeutic procedural-related pain that can be associated with considerable anxiety.

DESIGN

A prospective, descriptive and cross sectional study was conducted to investigate the prevalence of procedures or situations that probably induced anxiety and/or pain in children in an emergency room.

METHODS

Procedural pain and anxiety were evaluated in children and adolescents (8-16 years) who were admitted to the emergency department of a paediatric hospital between February-September 2010. Children rated their pain and anxiety using a 100-mm visual analogue scale.

RESULTS

A total of 252 children with a mean age of 10·1 years were evaluated. Four-hundred fifty-nine procedures were completed, with an average of 1·82 events/child. Of these procedures, 369 (80·4%) were rated painful and 357 (77·8%) were rated stressful. The most frequently reported procedural pain or stressful episodes were peripheral catheterization, clinical examination and vascular puncture. Overall, 32·5% of the painful events were rated severe, 32·0% were rated moderate and 35·5% were rated slight. However, 30% of the stressful events were rated severe, 38·9% were rated moderate and 31·1% were rated slight. Peripheral catheterization was rated severe in 58 children (33·9%), moderate in 55 children (32·2%) and slight in 58 (33·9%) children.

CONCLUSION

This study provides data on common emergency department procedures that cause pain and anxiety in children and young adolescents. Healthcare providers must consider the best psychological and pharmacological interventions to reduce procedural anxiety and pain.
