Expected and reported pain in children undergoing ear piercing: a randomized trial of preparation by parents

Sedation Practices for Lumbar Punctures in Patients With Acute Lymphoblastic Leukemia: A Multicenter Retrospective Study Using Pediatric Health Information Systems

BACKGROUND

Sedation is often used to reduce pain and anxiety in pediatric patients with acute lymphoblastic leukemia (ALL) undergoing lumbar punctures (LPs). There is a potential for long-term effects on neurocognition with repeat sedative exposures in young children. The purpose of this study is to determine the practice habits regarding sedation for LPs in pediatric patients with ALL among multiple institutions.

METHODS

This is a retrospective study of 48 hospitals in the Pediatric Health Information Systems (PHIS) between October 2015 and December 2019. Children 1 to 18 years old with ALL who received intrathecal chemotherapy in an outpatient setting were included. We analyzed the prevalence of anesthesia usage and the types of anesthetics used.

RESULTS

Of the 16,785 encounters with documented use of anesthetic medications, intravenous and inhaled anesthetics were used in 16,486 (98.2%) and local anesthetics alone in 299 (1.8%). The most commonly used medications used for sedation were propofol (n=13,279; 79.1%), midazolam (n=4228; 25.2%), inhaled fluranes (n=3169; 18.9%), and ketamine (n=2100; 12.5%).

CONCLUSION

The majority of children's hospitals in the United States use intravenous and inhaled anesthetics for routine therapeutic LPs in pediatric patients with ALL. Propofol is one of the most common medications used for sedation.

The effectiveness of a preoperative multi-component non-pharmacologic preparation on post-tonsillectomy pain: A randomized controlled clinical trial

INTRODUCTION

Tonsillectomy is a painful operation and some studies have suggested that preoperative non-pharmacologic preparations may decrease postoperative pain. In this randomized clinical trial study, we decided to determine which is more effective in the post-tonsillectomy pain; an informative booklet or a costly, time consuming, sophisticated, and multi-component preparation program.

MATERIALS AND METHODS

Patients were randomly assigned into two groups. In the booklet group, children and their parents only received an informative booklet as routine information preparation. On the other hand, in the multi-component group; in addition to receiving the same booklet, children and their parents received our multi-component pre-operative preparation program. The following items were included in the package: preoperative tour in the ward, an educational DVD, and therapeutic play intervention. All patients were observed at least for 8 h as a day case or ambulatory tonsillectomy. The pain score was recorded according to the visual analog scale for seven days. Finally, the post-tonsillectomy pain scores were compared in the two groups. The multi-component group included 121 children and booklet group 120.

RESULTS

Minimum and maximum age was 9 and 12 years. Regarding post-tonsillectomy pain, we found no significant difference between the multi-component group and the booklet group.

CONCLUSION

Our data revealed that a new concept which is more cost-effective and concise booklet is as effective as costly and sophisticated methods in post-tonsillectomy pain among 9-12 years old children.

Parent-Child Reminiscing about Past Pain as a Preparatory Technique in the Context of Children's Pain: A Narrative Review and Call for Future Research

Pain permeates childhood and remains inadequately and/or inconsistently managed. Existing research and clinical practice guidelines have largely focused on factors influencing the immediate experience of pain. The need for and benefits of preparing children for future pain (e.g., painful procedures) has been well established. Despite being a robust predictor of future pain and distress, memories of past painful experiences remain overlooked in pediatric pain management. Just as autobiographical memories prepare us for the future, children’s memories for past pain can be harnessed to prepare children for future painful experiences. Children’s pain memories are malleable and can be reframed to be less distressing, thus reducing anticipatory distress and promoting self-efficacy. Parents are powerful agents of change in the context of pediatric pain and valuable historians of children’s past painful experiences. They can alter children’s pain memories to be less distressing simply by talking, or reminiscing, about past pain. This narrative review summarizes existing research on parent–child reminiscing in the context of acute and chronic pediatric pain and argues for incorporation of parent–child reminiscing elements into preparatory interventions for painful procedures.

Physiologic Stress of Ear Punch Identification Compared with Restraint Only in Mice

Social housing of laboratory rodents is recommended whenever possible to encourage natural behavior and social dynamics. Several identification methods are used to distinguish rodents from one another. One of the most common means of identifying mice is ear punching. The effect of ear punching for identification or genotyping on the welfare of mice remains a concern, because this method negatively affects welfare in other species. To assess the influence of ear punching on the welfare of mice, we implanted telemetry units in 6 female Swiss-Webster mice and monitored heart rate, body temperature, and activity after various routine procedures. The physiologic and behavioral responses to restraint (by scruffing) only, restraint and ear punching, and routine handling for husbandry were evaluated. The mean heart rate of mice after receiving an ear punch was significantly higher than baseline values at 30 min after the procedure, and the mean body temperature was significantly increased over baseline for at least 1 h. The heart rate, body temperature, and activity levels of mice after scruffing only and routine handling did not differ from baseline values. The proportion of time mice spent head grooming, a potentially nocifensive behavior, was increased immediately after ear punching and began to decline by 60 min. We show that the physiologic stress of mice receiving an ear punch was greater than that from restraint (scruffing) alone, whereas behavioral indices of pain were unchanged, suggesting that ear punching causes a transient response in mice.

Paediatric Pain Medicine: Pain Differences, Recognition and Coping Acute Procedural Pain in Paediatric Emergency Room

Paediatric pain and its assessment and management are challenging for medical professionals, especially in an urgent care environment. Patients in a paediatric emergency room (PER) often undergo painful procedures which are an additional source of distress, anxiety, and pain. Paediatric procedural pain is often underestimated and neglected because of various myths, beliefs, and difficulties in its evaluation and treatment. However, it is very different from other origins of pain as it can be preventable. It is known that neonates and children can feel pain and that it has long-term effects that last through childhood into adulthood. There are a variety of pain assessment tools for children and they should be chosen according to the patient’s age, developmental stage, communication skills, and medical condition. Psychological factors such as PER environment, preprocedural preparation, and parental involvement should also be considered. There are proven methods to reduce a patient’s pain and anxiety during different procedures in PER. Distraction techniques such as music, videogames, virtual reality, or simple talk about movies, friends, or hobbies as well as cutaneous stimulation, vibration, cooling sprays, or devices are effective to alleviate procedural pain and anxiety. A choice of distraction technique should be individualized, selecting children who could benefit from nonpharmacological pain treatment methods or tools. Nonpharmacological pain management may reduce dosage of pain medication or exclude pharmacological pain management. Most nonpharmacological treatment methods are cheap, easily accessible, and safe to use on every child, so it should always be a first choice when planning a patient’s care. The aim of this review is to provide a summary of paediatric pain features, along with their physiology, assessment, management, and to highlight the importance and efficacy of nonpharmacological pain management in an urgent paediatric care setting.

Settling for second best: when should doctors agree to parental demands for suboptimal medical treatment?

BACKGROUND

Doctors sometimes encounter parents who object to prescribed treatment for their children, and request suboptimal substitutes be administered instead (suboptimal being defined as less effective and/or more expensive). Previous studies have focused on parental refusal of treatment and when this should be permitted, but the ethics of requests for suboptimal treatment has not been explored.

METHODS

The paper consists of two parts: an empirical analysis and an ethical analysis. We performed an online survey with a sample of the general public to assess respondents' thresholds for acceptable harm and expense resulting from parental choice, and the role that religion played in their judgement. We also identified and applied existing ethical frameworks to the case described in the survey to compare theoretical and empirical results.

RESULTS

Two hundred and forty-two Mechanical Turk workers took our survey and there were 178 valid responses (73.6%). Respondents' agreement to provide treatment decreased as the risk or cost of the requested substitute increased (p<0.001). More than 50% of participants were prepared to provide treatment that would involve a small absolute increased risk of death for the child (<5%) and a cost increase of US$<500, respectively. Religiously motivated requests were significantly more likely to be allowed (p<0.001). Existing ethical frameworks largely yielded ambiguous results for the case. There were clear inconsistencies between the theoretical and empirical results.

CONCLUSION

Drawing on both survey results and ethical analysis, we propose a potential model and thresholds for deciding about the permissibility of suboptimal treatment requests.

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

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

Teddy and I Get a Check-Up: A Pilot Educational Intervention Teaching Children Coping Strategies for Managing Procedure-Related Pain and Fear

Background. Pediatric medical information provision literature focuses on hospitalization and surgical procedures, but children would also benefit from an educational program regarding more commonly experienced medical procedures (e.g., needles, general check-up). Objective. To determine whether an evidence-based educational program reduced children's ratings of fear of and expected pain from medical stimuli and increased their knowledge of procedural coping strategies. Methods. An educational, interactive, developmentally appropriate Teddy Bear Clinic Tour was developed and delivered at a veterinary clinic. During this tour, 71 5-10-year-old children (Mage = 6.62 years, SD = 1.19) were taught about medical equipment, procedures, and coping strategies through modelling and rehearsal. In a single-group, pretest posttest design, participants reported their fear of and expected pain from medical and nonmedical stimuli. Children were also asked to report strategies they would use to cope with procedural fear. Results. Children's ratings for expected pain during a needle procedure were reduced following the intervention. No significant change occurred in children's fear of needles. Children reported more intervention-taught coping strategies at Time 2. Conclusions. The results of this study suggest that an evidence-based, interactive educational program can reduce young children's expectations of needle pain and may help teach them procedural coping strategies.

Children's self reported discomforts as participants in clinical research

INTRODUCTION

There is little empirical evidence on children's subjective experiences of discomfort during clinical research procedures. Therefore, Institutional Review Boards have limited empirical information to guide their decision-making on discomforts for children in clinical research. To get more insight into what children's discomforts are during clinical research procedures, we interviewed a group of children on this topic and also asked for suggestions to reduce possible discomforts.

MATERIALS AND METHODS

Forty-six children (aged 6-18) participating in clinical research studies (including needle-related procedures, food provocation tests, MRI scans, pulmonary function tests, questionnaires) were interviewed about their experiences during the research procedures. Thematic analysis was used to analyze the interviews.

RESULTS

The discomforts of the interviewed children could be divided into two main groups: physical and mental discomforts. The majority experienced physical discomforts during the research procedures: pain, shortness of breath, nausea, itchiness, and feeling hungry, which were often caused by needle procedures, some pulmonary procedures, and food provocation tests. Mental discomforts included anxiousness because of anticipated pain and not knowing what to expect from a research procedure, boredom and tiredness during lengthy research procedures and waiting, and embarrassment during Tanner staging. Children's suggestions to reduce the discomforts of the research procedures were providing distraction (e.g. watching a movie or listening to music), providing age-appropriate information and shortening the duration of lengthy procedures.

DISCUSSION

Our study shows that children can experience various discomforts during research procedures, and it provides information about how these discomforts can be reduced according to them. Further research is needed with larger samples to study the number of children that experience these mentioned discomforts during research procedures in a quantitative way.

Procedural pain and patient-reported side effects with weekly injections of subcutaneous methotrexate in children with rheumatic disorders

BACKGROUND

Despite the widespread use of subcutaneous methotrexate in treating pediatric rheumatic disorders, the amount of pain associated with the injections has not been quantified. Our study aims 1) to quantify the amount of pain associated with subcutaneous injections of methotrexate, 2) to explore predictors of pain, 3) to determine the frequency of patient-reported clinical adverse effects of methotrexate, and 4) identify coping strategies of patients and caregivers.

METHODS

Patients aged 4-17 years with rheumatologic diseases who were receiving weekly subcutaneous methotrexate injections for at least 4 weeks were invited to participate in this prospective cohort study. They were trained to use the Faces Pain Scale-Revised (FPS-R) and Faces, Legs, Arms, Cry, Consolability (FLACC) tools to rate pain associated with the injections. All patients underwent focused interviews exploring their experiences with methotrexate injections.

RESULTS

Forty-one patients consented to the study. The mean age was 11.2 years (SD = 3.9 years) and 68% were female. Most patients were diagnosed with JIA (73%). Mean duration of methotrexate therapy was 2.5 years (SD = 2.1 yrs). All but one of the patients used methotrexate 25 mg/ml solution for injection in 1 cc or 3 cc syringe with 30 gauge ½" needle. Median amount of pain was 2/10 on the FPS-R and 1/10 on the FLACC. Higher intensity of pain was significantly associated with presence of side effects (p = 0.004), but not duration of therapy (p = 0.20) or age (p = 0.24). Most participants (61%) experienced at least one adverse effect; nausea (56%) and vomiting (34%) were the most common symptoms reported. Patients and caregivers reported using ice (34%), comfort positions (51%), rewards (49%), reassurance (54%), distraction (51%), and analgesic medications (22%) to cope with the injections.

CONCLUSION

Subcutaneous injections of methotrexate are associated with a mild amount of pain. Presence of side effects may amplify the amount of perceived pain. Clinicians can apply this knowledge when counseling patients and family members about methotrexate therapy.

'Making the bad things seem better': coping in children receiving healthcare

The focus of children's healthcare literature has been the delivery of services to children and their parents, little attention has been paid to how children cope with receiving such care. In this paper we use a literature scoping method to bring together the literature on how medical talk can engage or isolate children, consider the environmental factors which can help children to be engaged and discuss an ethical symmetry approach. We propose that an ethical symmetry approach would provide a framework for healthcare teams to explore how to optimize children's engagement with their healthcare.

A systematic review of faces scales for the self-report of pain intensity in children

CONTEXT

Numerous faces scales have been developed for the measurement of pain intensity in children. It remains unclear whether any one of the faces scales is better for a particular purpose with regard to validity, reliability, feasibility, and preference.

OBJECTIVES

To summarize and systematically review faces pain scales most commonly used to obtain self-report of pain intensity in children for evaluation of reliability and validity and to compare the scales for preference and utility.

METHODS

Five major electronic databases were systematically searched for studies that used a faces scale for the self-report measurement of pain intensity in children. Fourteen faces pain scales were identified, of which 4 have undergone extensive psychometric testing: Faces Pain Scale (FPS) (scored 0-6); Faces Pain Scale-Revised (FPS-R) (0-10); Oucher pain scale (0-10); and Wong-Baker Faces Pain Rating Scale (WBFPRS) (0-10). These 4 scales were included in the review. Studies were classified by using psychometric criteria, including construct validity, reliability, and responsiveness, that were established a priori.

RESULTS

From a total of 276 articles retrieved, 182 were screened for psychometric evaluation, and 127 were included. All 4 faces pain scales were found to be adequately supported by psychometric data. When given a choice between faces scales, children preferred the WBFPRS. Confounding of pain intensity with affect caused by use of smiling and crying anchor faces is a disadvantage of the WBFPRS.

CONCLUSIONS

For clinical use, we found no grounds to switch from 1 faces scale to another when 1 of the scales is in use. For research use, the FPS-R has been recommended on the basis of utility and psychometric features. Data are sparse for children below the age of 5 years, and future research should focus on simplified measures, instructions, and anchors for these younger children.

Procedural pain management for children receiving physiotherapy

PURPOSE

This article provides an overview of literature relevant to the prevention and relief of pain and distress during physiotherapy procedures, with guidance for physiotherapists treating children.

SUMMARY OF KEY POINTS

Physiotherapists are generally well trained in assessing and managing pain as a symptom of injury or disease, but there is a need to improve the identification and management of pain produced by physiotherapy procedures such as stretching and splinting. In contrast to physiotherapy, other health care disciplines, such as dentistry, nursing, paediatrics, emergency medicine, and paediatric psychology, produce extensive literature on painful procedures. Procedural pain in children is particularly important because it can lead to later fear and avoidance of necessary medical care.

RECOMMENDATIONS

We emphasize the need for physiotherapists to recognize procedural pain and fear in the course of treatment using verbal, nonverbal, and contextual cues. We present many methods that physiotherapists can use to prevent or relieve procedural pain and fear in paediatric patients and provide an example of a simple, integrated plan for prevention and relief of distress induced by painful procedures.

Anxiety influences children's memory for procedural pain

OBJECTIVE

To examine the effects of temperament and trait anxiety on memory for pain.

METHODS

Three dimensions of temperament, as well as trait anxiety, were assessed in 36 children (five to 12 years of age) undergoing dental procedures; after the procedure, the children provided pain ratings. Following a six- to eight-week delay, the children reported how much pain they remembered.

RESULTS

Most children (85%) accurately recalled their pain. Temperament had no significant effect, but trait-anxious children showed a greater likelihood of recalling more pain than they initially reported, suggesting that they may negatively distort recollections of painful experiences.

CONCLUSIONS

When treating children, in particular trait-anxious children, clinicians should consider what children remember as part of pain management intervention.

Behavioral approaches to anxiety and pain management for pediatric venous access

Pediatric venous access causes unnecessary anxiety and pain in children and, in turn, can have detrimental consequences. Behavioral approaches to pediatric venous access distress management can be organized temporally. Specifically, preparation before the procedure includes providing children with sensory and procedural information in an age-appropriate manner and providing training in coping skills. It is important to consider the timing, format, and content of the approach to provide optimal preparation for the unique circumstances of the individual patient. In addition to the child patient, preparing parents and teaching them which specific behaviors might be most helpful to their child should prove valuable to both patient and parents. During the procedure, there are benefits to providing secure and comfortable positioning. In addition, researchers recommend that adults encourage children to cope and actively engage children in distracting activities. For infants, there is support for the distress-mitigation properties of swaddling, skin-to-skin contact, breastfeeding, and sucrose. After venous access, distraction and encouragement of coping should speed recovery. In sum, research in behavioral approaches to pediatric pain management has provided recommendations for minimizing children's anxiety and pain associated with venous access.

Children's pre-operative tonsillectomy pain education: clinical outcomes

OBJECTIVE

To examine the effects of pre-operative tonsillectomy pain education on children's (7-13 years) self-reported pre-operative anxiety and post-operative clinical outcomes (i.e., anxiety, pain intensity, quality of pain and sleep, oral intake, perceptions of pre-operative education, and pain expectation).

METHOD

A prospective, repeated measures, quasi-experimental design using an age appropriate pain education booklet (n = 30) and a standard care comparison group (n = 30) was employed to investigate children's pre- and post-education anxiety and post-operative tonsillectomy with or without adenoidectomy subjective experiences in the hospital and home settings. Group comparisons were performed using the Wilcoxon test, Fisher's exact test, repeated measures analysis of variance, and mixed model regression.

RESULTS

There were no significant differences between groups for measures of anxiety, pain intensity, quality of pain and sleep, oral intake, or expected pain. There was no change in anxiety before or after pre-operative education (P = 0.85). Ninety-six percent (n = 25) of the children in the intervention group reported that pre-operative pain education helped with their post-operative pain and 72% (n = 16) in the control group stated that it would be helpful to learn about pain before surgery. The majority of children in both the intervention and control groups (96%, 91%, respectively) stated learning about the 0-10 numeric pain intensity scale helped or would be helpful to learn pre-operatively.

CONCLUSION

Pre-operative pain education did not affect anxiety. Children valued pre-operative pain education. Pre-operative pain education may influence children's perceptions of medical care.

Evidence-based assessment of pediatric pain

OBJECTIVE

To conduct an evidence-based review of pediatric pain measures.

METHODS

Seventeen measures were examined, spanning pain intensity self-report, questionnaires and diaries, and behavioral observations. Measures were classified as "Well-established," "Approaching well-established," or "Promising" according to established criteria. Information was highlighted to help professionals evaluate the instruments for particular purposes (e.g., research, clinical work).

RESULTS

Eleven measures met criteria for "Well-established," six "Approaching well-established," and zero were classified as "Promising."

CONCLUSIONS

There are a number of strong measures for assessing children's pain, which allows professionals options to meet their particular needs. Future directions in pain assessment are identified, such as highlighting culture and the impact of pain on functioning. This review examines the research and characteristics of some of the commonly used pain tools in hopes that the reader will be able to use this evidence-based approach and the information in future selection of assessment devices for pediatric pain.

Effects of preparatory information and distraction on children's cold-pressor pain outcomes: A randomized controlled trial

This experimental study investigated whether preparatory sensory information was more effective in managing children's pain when coupled with a distraction technique. Seventy-eight children aged 7-12 years were randomly allocated to 1 of 4 experimental conditions. They were given either a detailed sensory description of an imminent painful event (cold-pressor arm immersion in 10 degrees C water) or control instructions lacking sensory information. During the cold-pressor task, half the sample received an imagery-based distraction intervention. Pain measures included immersion tolerance, self-reported pain intensity, and facial pain responses. Self-reported coping style was assessed using the Pain Coping Questionnaire [Reid, G. J., Gilbert, C. A., & McGrath, P. J. (1998). The pain coping questionnaire: Preliminary validation. Pain, 76, 83-96]. The effects of information provision interacted with distraction for pain intensity but not pain tolerance. Children given sensory preparation reported less intense pain when this was coupled with distraction than when it was not. Children with a distraction-based coping style showed greater tolerance when assigned to a condition congruent with their coping style. These findings suggest ways to better prepare children for painful medical procedures.

Parental pain expectancy as a mediator between child expected and experienced procedure-related pain intensity during painful medical procedures

OBJECTIVES

The aim of this prospective investigation was to evaluate child and parental expectancies as a predictor of pain perception in pediatric oncology patients undergoing painful medical procedures.

METHODS

Forty-five children with leukemia or non-Hodgkin lymphoma and their parents rated expected and experienced pain during lumbar punctures at baseline, during intervention (ie, cognitive-behavior therapy) administered by a therapist and when children were using cognitive-behavior therapy skills independently.

RESULTS

Parental and child expectancies were significantly correlated. Parents consistently expected their children to experience more pain than children were expecting themselves. Parental expectancy was found to mediate the relationship between child expected and experienced pain during every phase of the study.

DISCUSSION

It is concluded that parental expectancies are reliable predictors of pediatric procedure-related pain and possible useful targets for psychologic interventions to manage such pain.

Online Psychological Treatment for Pediatric Recurrent Pain: A Randomized Evaluation

OBJECTIVE

To evaluate the efficacy of a distance treatment delivered through Internet and telephone for pediatric recurrent pain.

METHODS

Forty-seven participants (9-16 years of age) were randomly assigned to either an Internet-based treatment or a standard medical care waitlist. Treatment employed a Web-based manual for children and parents with weekly therapist contact by telephone or e-mail. At 1- and 3-month follow-ups, participants were assessed on the outcome variables of pain and quality of life. A 50% reduction in diary pain scores was considered clinically significant.

RESULTS

Significant between-group differences were found: 71 and 72% of the treatment group achieved clinically significant improvement at the 1- and 3-month follow-ups, respectively, whereas only 19 and 14% of the control group achieved the criterion. No significant differences were found on the quality of life variable.

CONCLUSIONS

Distance methods have considerable potential for making effective treatments more accessible with lower associated costs.

Pain- and distress-reducing interventions for venepuncture in children

OBJECTIVE

To compare the effect of eutectic mixture of local anaesthetics (EMLA) and a placebo cream on reported pain and observed distress associated with venepuncture, and to investigate effects of procedural information before and distraction during venepuncture.

METHODS

Children 3-12 years of age undergoing venepuncture under five experimental and a control condition reported their pain at venepuncture on visual scales. Distress was observed when the child entered the waiting room, just before, and during venepuncture.

RESULTS

Distress increased over the measurement occasions, but a distress-reducing effect of EMLA only was found at the actual venepuncture. The placebo diminished the reported pain, but the effect of EMLA was larger. Procedural information and distraction showed no effects.

CONCLUSIONS

EMLA reduces pain from venepuncture. The placebo effect probably results from desirable responding. Behavioural distress is a more direct measure than self-reported pain. More sophisticated designs should be used for the provision of procedural information and distraction.

Treatment expectations for CAM interventions in pediatric chronic pain patients and their parents

Patient expectations regarding complementary and alternative medicine (CAM) interventions have important implications for treatment adherence, attrition and clinical outcome. Little is known, however, about parent and child treatment expectations regarding CAM approaches for pediatric chronic pain problems. The present study examined ratings of the expected benefits of CAM (i.e. hypnosis, massage, acupuncture, yoga and relaxation) and conventional medicine (i.e. medications, surgery) interventions in 45 children (32 girls; mean age = 13.8 years ± 2.5) and parents (39 mothers) presenting for treatment at a specialty clinic for chronic pediatric pain. Among children, medications and relaxation were expected to be significantly more helpful than the remaining approaches (P < 0.01). However, children expected the three lowest rated interventions, acupuncture, surgery and hypnosis, to be of equal benefit. Results among parents were similar to those found in children but there were fewer significant differences between ratings of the various interventions. Only surgery was expected by parents to be significantly less helpful than the other approaches (P < 0.01). When parent and child perceptions were compared, parents expected hypnosis, acupuncture and yoga, to be more beneficial than did children, whereas children expected surgery to be more helpful than did parents (P < 0.01). Overall, children expected the benefits of CAM to be fairly low with parents' expectations only somewhat more positive. The current findings suggest that educational efforts directed at enhancing treatment expectations regarding CAM, particularly among children with chronic pain, are warranted.

Pre-event discussion and recall of a novel event: How are children best prepared?

We investigated the conditions under which information 1 day before a novel event influenced 6-year-olds' recall 2 weeks later. In Experiment 1A, four preparation conditions included either the event goals, goals with narration of the event actions and objects, photographs of the objects with goals and narration, or photographs with narration and child verbalization of the actions and objects. Compared with an irrelevant preparation control condition, goals with narration reduced errors, but correct recall was increased only when photographs were included. Child verbalization together with goals, narration, and photographs increased correct recall relative to goals with narration. In Experiment 1B, neither photographs nor preparation alone improved recall relative to the control condition. Experiment 2 found no further advantage of increasing children's participation in the preparation via questions. Overall, the impact of preevent information on memory is influenced by the nature of the information and the child's participation in the preparation.

Pediatric procedural pain

Pain is subjective. The pain response is individual and is learned through social learning and experience. Early pain experiences may play a particularly important role in shaping an individual's pain responses. Painful medical procedures such as immunizations, venipunctures and dental care, and minor emergency department procedures such as laceration repair, compose a significant portion of the average child's experience with painful events. Inadequate relief of pain and distress during childhood painful medical procedures may have long-term negative effects on future pain tolerance and pain responses. This article reviews the evidence for long-term negative effects of inadequately treated procedural pain, the determinants of an individual's pain response, tools to assess pain in children, and interventions to reduce procedural pain and distress. Future research directions and a model for conceptualizing and studying pediatric procedural pain are proposed.

Children's memory for pain: overview and implications for practice

Children's memories of painful experiences can have long-term consequences for their reaction to later painful events and their acceptance of later health care interventions. This review surveys research on children's memory for pain, emphasizing implications for clinical practice. Topics reviewed include consequences of children's memories of pain; the development of memory; differences between explicit (declarative, verbal, autobiographic) memory and implicit (nondeclarative, nonverbal) memory; and individual differences, situational, and methodologic factors affecting memories of pain. Methods to prevent the adverse consequences of remembered pain are addressed with reference to current research on editing or reframing memories.

PERSPECTIVE

This review covers topics of value to clinicians providing care to children undergoing painful procedures. Specific recommendations are offered regarding the importance of acknowledging and assessing children's previous memories of painful experiences, the type of information that benefits children before and after procedures, and the most appropriate questioning strategies. It might be possible to prevent or reduce the adverse effects of memories of pain.

Re-thinking family-centred care across the continuum of children's healthcare

BACKGROUND

The terms family-centred care (FCC) and family-centred services (FCS) are used interchangeably across the continuum of children's healthcare to encompass concepts of: parental participation in children's healthcare; partnership and collaboration between the healthcare team and parents in decision-making; family-friendly environments that normalize as much as possible family functioning within the healthcare setting; and care of family members as well as of children. However, authors from different professional and policy perspectives have used different definitions and literatures when arguing the evidence for FCC and FCS.

METHOD

A critical literature review and theoretical discussion exploring common concepts and issues forming the basis for a research agenda further strengthening of the evidence base for FCC. A systematic identification of constructs, concepts and empirical indicators is developed and applied to exemplars in pain and asthma that span the continuum of children's healthcare across acute and community settings.

CONCLUSIONS

The extent to which the concepts are supported by research and applied in practice remains unclear. We propose that re-thinking of FCC is required in order to develop a more coherent programme of research into the application of FCC theory in children's healthcare.

Nonsteroidal anti-inflammatory drugs for postoperative pain: a focus on children

Pain is a common symptom after surgery in children, and the need for effective pain management is obvious. For example, after myringotomy, despite the brief nature of the procedure, at least one-half of children have significant pain. After more extended surgery, such as tonsillectomy, almost all children have considerable pain longer than 7 days. Nonsteroidal anti-inflammatory drugs (NSAIDs) are useful for postoperative pain management because surgery causes both pain and inflammation. Several pediatric studies indicate NSAIDs are effective analgesics in the management of mild and moderate pain. In the treatment of severe pain, NSAIDs should be given with acetaminophen (paracetamol) or opioids, and the use of an appropriate regional analgesic technique should be considered. NSAIDs are more effective in preventing pain than in the relief of established pain. Pain following surgery is best managed by providing medication on a regular basis, preventing the pain from recurring. This proactive approach should be implemented for any procedure where postoperative pain is the likely outcome. In children, the choice of formulation can be more important than the choice of drug. Intravenous administration is preferred for children with an intravenous line in place; thereafter mixtures and small tablets are feasible options. Children dislike suppositories, and intramuscular administration should not be used in nonsedated children. Ibuprofen, diclofenac, ketoprofen and ketorolac are the most extensively evaluated NSAIDs in children. Only a few trials have compared different NSAIDs, but no major differences in the analgesic action are expected when appropriate doses of each drug are used. Whether NSAIDs differ in the incidence and severity of adverse effects is open to discussion. Because NSAIDs prevent platelet aggregation they may increase bleeding. A few studies indicate that ketorolac may increase bleeding more so than other NSAIDs, but the evidence is conflicting. Severe adverse effects of NSAIDs in children are very rare, but it is important to know about adverse effects in order to recognize and treat them when they do occur. NSAIDs are contraindicated in patients in whom sensitivity reactions are precipitated by aspirin (acetylsalicylic acid) or other NSAIDs. They should be used with caution in children with liver dysfunction, impaired renal function, hypovolemia or hypotension, coagulation disorders, thrombocytopenia, or active bleeding from any cause. In contrast, it seems that most children with mild asthma may use NSAIDs.
