Pain reduction during pediatric immunizations: evidence-based review and recommendations

Analysis of gluteal subcutaneous and muscle thickness in infants and children for application to intramuscular injection, autologous fat grafting, and gluteal artery perforator flaps

Background

To achieve improvements in intramuscular injection, autologous fat grafting, and gluteal artery perforator flaps in infants and children, the relationships of computed tomography (CT)-determined gluteal muscle thickness (MT) and subcutaneous tissue thickness (SCT) with age and body mass index (BMI) were analyzed.

Methods

Gluteal SCT and MT at ventrogluteal (VG) and dorsogluteal (DG) sites were measured in a standardized manner in 350 patients aged 0 to 6 years who had visited a tertiary hospital and had undergone abdominopelvic CT between January 2005 and December 2016. Recorded measurements were analyzed using one-way analysis of variance and stepwise multiple regression to identify the factors that were most closely related to MT and SCT.

Results

Subcutaneous tissue at VG sites was thinner than at DG sites, but not significantly so in any age group. Muscles tended to be thinner at VG sites in 4 to 7-year-old, but thicker at VG sites in 1 to 3-year-old, though the differences were not significant. MT in the VG and DG regions was found to be related to age, and SCT in these regions to be related to age and BMI.

Conclusions

The VG and DG sites should be considered as alternatives for intramuscular injection in infants and children when the anterolateral site is problematic. In addition, considering the gluteal MT and SCT of infants and children should help produce good results in autologous fat grafting and gluteal artery perforator flap harvesting.

Children's Pain and Distress at a Public Influenza Vaccination Clinic: A Parent Survey and Public Observation Study

Immunizations are a necessary but distressing and painful procedure that most infants and children regularly undergo. Each year, a tertiary pediatric hospital in Canada holds an influenza vaccination clinic for all staff and their families. Evidence-based interventions to reduce pain and distress in babies and children are used. Despite this, infants and children continue to be distressed throughout the vaccination procedure. The objectives of this study were to: (1) measure the prevalence of distress among infants and children before, during, and after vaccine administration at the clinic, and (2) evaluate parents' perception of their child(ren)'s distress before, during, and after vaccine administration and the effectiveness of pain management interventions used during the clinic. A cross-sectional design of naturalistic observation and parent surveys was used and data was analyzed using descriptive statistics. A total of 283 children between 6 months and 18 years were vaccinated at the clinic, with 52% observed to be distressed before, during, or after the procedure. There were 115 parents of 206 children that completed the survey; 47% of these parents perceived that their children were distressed before, during, or after vaccination, and 42% perceived that the pain treatments used for their child(ren) were very effective. The results of this study will continue to inform interventions for needle-related pain and distress management, as well as improvements for future public vaccination clinics.

Pharmacological interventions for reducing pain related to immunization or intramuscular injection in children: A mixed treatment comparison network meta-analysis of randomized controlled clinical trials

Various interventions were observed to reduce pain following vaccination in children. This study is a network meta-analysis comparing pharmacological interventions. Electronic databases were searched for appropriate randomized controlled clinical trials comparing active pharmacological agents to reduce pain following vaccination or intramuscular injection in neonates, infants, or children. Pain score was the primary outcome measure. Random effects model was used for generating pooled estimates. A total of 23 studies were included in the network meta-analysis. Topical eutectic mixture of local anesthetics (EMLA) significantly reduced pain scores. Crying time was also observed to be lower with vapocoolant spray and 25% sucrose and glucose solutions. Quality of the evidence was observed to be either low or very low. Topical EMLA significantly reduce pain following intramuscular injections particularly vaccination. However, due to low grade quality of the evidence, more studies are obligatory.

Efficacy of Non-pharmacological Methods of Pain Management in Children Undergoing Venipuncture in a Pediatric Outpatient Clinic: A Randomized Controlled Trial of Audiovisual Distraction and External Cold and Vibration

PURPOSE

Venipuncture generates anxiety and pain in children. The primary aim of the study was to evaluate two non-pharmacological techniques, vibration combined with cryotherapeutic topical analgesia by means of the Buzzy® device and animated cartoons, in terms of pain and anxiety relief during venipuncture in children.

DESIGNS AND METHODS

150 children undergoing venipuncture were randomized into four groups: the 'no method' group, the Buzzy® device group, the animated cartoon group and the combination of Buzzy® and an animated cartoon group. Children's pain and anxiety levels along with parents' and nurses' anxiety levels were evaluated by means of validated grading scales.

RESULTS

Overall children's pain increased less in the non-pharmacological intervention groups as compared to the group without intervention. Notably, the difference was statistically significant in the animated cartoon group for children's perception of pain. Children's anxiety and parents' anxiety decreased more in non-pharmacological interventions groups as compared to the group without intervention.

CONCLUSIONS

The study showed the effectiveness of non-pharmacological methods of pain management during venipuncture. Notably, distraction with animated cartoons was superior in terms of children's perception of pain when compared to Buzzy®, and to the combination of cartoons and Buzzy®. Buzzy® was significantly effective at the secondary analysis for children younger than 9. Children's and parents' anxiety is decreased by non-pharmacological methods. Furthermore, nurses' involvement in pediatric care can be enhanced.

PRACTICE IMPLICATIONS

Non-pharmacological methods of pain management during venipuncture represent an easy way to achieve an increased level of compliance among children and parents.

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.

Improving vaccine-related pain, distress or fear in healthy children and adolescents-a systematic search of patient-focused interventions

OBJECTIVE

The WHO recently highlighted the need for research into potential interventions that can be used to mitigate pain during mass vaccinations, in addition to interventions specific for adolescents. The current review examines the literature on potential interventions that can be used during mass vaccination settings in healthy individuals between the ages of 4 and 15 years old.

METHODS

Criteria for inclusion were: 1)participants between the ages of 4-15 years, 2)interventions that were patient-focused, 3)vaccinations in healthy individuals, 4)outcome measures to include self-reported pain, fear or distress.

RESULTS

Twenty-seven articles were identified with a total of 31 interventions. Eleven interventions used injection-site specific interventions, 17 used patient-led interventions and three used a combination of both site-specific and patient-led interventions.

CONCLUSION

Interventions using coolant and vibration together, as well as a combination of site-specific and patient-led interventions, showed the most consistent effects in reducing self-reported pain, fear or distress.

Immunizations under sedation at a paediatric hospital in Melbourne, Australia from 2012-2016

BACKGROUND

Sedation for immunizations is of particular importance in a subset of paediatric patients with anxiety disorders, needle phobia, developmental or behavioural disorders. The Royal Children's Hospital (RCH) Melbourne offers a unique immunization under sedation service for these patients. We aimed to evaluate the number and types of patients using inpatient sedation for immunizations, distraction and sedation techniques used, and outcomes of these procedures.

METHODS

A medical record review was conducted on all patients who had immunization under sedation between January 2012 to December 2016 in the RCH Day Medical Unit (DMU).

RESULTS

A total of 139 children and adolescents had 213 vaccination encounters. More than half of the vaccination encounters involved multiple vaccines. A total of 400 vaccines were administered. One third of patients (32.3%) had multiple DMU admissions for vaccinations. The median age of patients was 13 years. There were only 10 (4.7%) failed attempts at vaccination; all due to patient non-compliance with prescribed sedation. The majority of patients (58.9%) had a diagnosis of needle phobia. Sedation was most commonly adequately achieved with inhaled nitrous oxide (54.7% sole agent). Midazolam was often used as an adjunct therapy (42.8%). Local anaesthetic cream or play therapy, were used in only 5.9% and 3.9% of patients respectively, although this may reflect poor documentation rather than actual practice.

CONCLUSIONS

For a subset of paediatric patients for which standard immunization procedures have failed, distraction techniques and conscious sedation enable immunizations to be given safely and effectively. Future research will develop protocols to streamline immunization procedures under sedation.

Effectiveness of vibratory stimulation on needle-related procedural pain in children: a systematic review protocol

REVIEW QUESTION/OBJECTIVE

The objective of this systematic review is to identify, evaluate and synthesize evidence on the effectiveness of vibratory stimulation to reduce needle-related procedural pain in children aged 18 years and under.The review will address the following question: Is vibratory stimulation effective in reducing needle-related procedural pain in children aged 18 years and under, in comparison with no stimulation for needle-related procedures?

Differences in Immunization Site Pain in Toddlers Vaccinated With Either the 10- or the 13-Valent Pneumococcal Conjugate Vaccine

BACKGROUND

Immunization site pain is a common and unpleasant experience for both children and adults. It is a source of anxiety and distress and may ultimately result in nonadherence to vaccination schedules. There is limited information on how different brands of vaccines affect the intensity of immediate pain at the time of vaccine injection.

METHODS

Children in the United Kingdom (n = 178) were randomized to receive a booster dose of either the 10- or the 13-valent pneumococcal conjugate vaccine (PCV-10 or PCV-13). Immediate immunization site pain was assessed using validated pain assessment tools and crying time to investigate factors that may interfere with parental compliance to vaccination.

RESULTS

Pain measurements were available for n ≥ 74 and n ≥ 78 PCV-10 and PCV-13 recipients, respectively. PCV-13 recipients had significantly higher scores on the observer-rated modified behavioral pain scale than did those receiving PCV-10. No significant differences in the induction of pain between the 2 vaccines were found when a parent-rated pain assessment tool or crying time was used.

CONCLUSIONS

PCV-10 administration was associated with slightly less acute pain compared with the injection of PCV-13, but the size of the difference was small and is of unknown clinical significance.

Pain caused by measles, mumps, and rubella vaccines: A systematic literature review

PURPOSE

The risk of post-vaccination adverse events (AEs) is a primary public health concern. Among the AEs, pain is a significant source of anxiety for both children and their parents. This review describes and assesses the intensity of pain experienced by children post-vaccination with widely used Measles-Mumps-Rubella (MMR) vaccines.

METHODS

A systematic literature search was conducted in Pubmed, Embase and Cochrane to identify publications describing immediate pain at injection site (primary objective) or pain within days (secondary objective) after 2 specific MMR vaccines. Immediate pain ('acute pain' according to the Brighton Collaboration case definition) was defined as pain occurring at the time or within 5min of injection.

RESULTS

Four studies, which compared the intensity of immediate injection site pain experienced by children after MMR vaccination, were identified. Various pain assessment tools and methods were used to quantify the intensity of pain, including the median difference in Visual Analog Scale scores between vaccine groups. All four studies showed significantly less immediate pain caused by Priorix (GSK Vaccines) compared with M-M-R II (Merck & Co., Inc.).

CONCLUSIONS

To our knowledge, this review summarizes for the first time the available scientific evidence on the intensity of pain following different MMR vaccines. It highlights that MMR vaccines can differ in terms of immediate pain. Further research may be needed to better understand the underlying reason for this observation. In this context, it is very important to understand which physicochemical properties are most relevant for the immediate pain profile of a vaccine to thereby support the development of vaccines with the best possible immediate pain profile.

Advances Towards Painless Vaccination and Newer Modes of Vaccine Delivery

Vaccines have been successful in reducing the mortality and morbidity, but most of them are delivered by intramuscular or intravenous route. They are associated with pain to the baby and bring lot of anxiety for the parents. There has been a marked increase in the number of injections required in first two years of life for completing the vaccination schedule. Hence, there is a need to have a painless vaccine delivery system. Numerous new routes of vaccination like, oral, nasal and transdermal routes are being tried. Oral polio and intranasal influenza have already been a success. Other newer approaches like edible vaccines, nasal sprays, dry powder preparations, jet injectors, microneedles and nanopatches are promising in delivering painless vaccines. Many of them are under clinical trials. These vaccine delivery systems will not only be painless but also cost effective, safe and easy to administer in mass population. They may be devoid of the need of cold chain. Painless delivery system will ensure better compliance to vaccination schedule.

Parent Attitudes Toward Pain Management for Childhood Immunizations

OBJECTIVES

Evidence-based pain-limiting strategies for pediatric immunizations remain underutilized, with barriers identified to date mostly pertaining to health care providers and systems of care. The present study sought to quantify and investigate parent attitudes toward pain management as another potential barrier to the routine use of pain-mitigating strategies during immunizations.

MATERIALS AND METHODS

Questionnaires measuring parent attitudes, willingness to pay, and perceived barriers for using pain management for immunizations were completed by 259 parent/guardians of children ages 0 to 5 years attending appointments at an urban primary care clinic in the Midwestern United States.

RESULTS

Parent attitudes toward pain management for immunization were relatively normally distributed and varied from strongly positive to negative, with 33% of parents disagreeing that they were concerned about the pain their child may experience and 50% agreeing that there are no lasting negative effects from immunization pain. Negative parent attitudes were associated with willingness to spend less in money or time for pain management and with greater perceived significance of cost, time, and other barriers for using pain-mitigating strategies.

DISCUSSION

Some parents perceive limited value in trying to reduce pain during immunizations such that they may be hesitant to invest much time or effort in interventions. Greater success of translating evidence-based pain management into practice therefore may require accounting for differences in parent attitudes by tailoring educational efforts and pain management options accordingly.

[Do analgesic sweet solutions in neonates influence glycemia? A literature review]

Sweet solutions are one of the most widely used nonpharmacologic analgesics used for newborns. They alleviate mild to moderate pain induced by painful procedures. They are used daily in neonatal intensive care units before a venepuncture or a heel stick, especially for a blood-sugar measurement. It is agreed that analgesic sweet solutions do not modify glycemia results. This nevertheless remains a recurrent question that the present review attempts to answer.

Parent-Child Behavioral Interactions during Pediatric Immunizations in a Latino Sample

A number of studies have found that specific parent behaviors are strong predictors of child medical procedural distress or coping. These findings have informed treatment protocols to lower children's distress during invasive medical events. However, the vast majority of this research has been conducted on predominately North American, English-speaking, Caucasian samples. One growing population that faces healthcare disparities is Latinos living in the U.S. The purpose of this study was to explore the types and frequencies of parent and child behavior, as well as the association between parent behavior and child distress and coping in a sample of Spanish-speaking Latino-American parent-child dyads. Nineteen 4- to 6-year-old Latino children receiving routine immunizations and their parents were video recorded, and behaviors were coded with commonly used schemes. The findings suggest that there may be differences in Latino parent and child behavior when compared to the extant - predominately English-speaking, Caucasian North American - literature. This study provides an initial examination of how cultural constructs may relate to parent-child behavior in Spanish-speaking Latino families in the U.S. Future research is warranted as findings can inform culturally sensitive clinical practice.

Understanding Non-Completion of the Human Papillomavirus Vaccine Series: Parent-Reported Reasons for Why Adolescents Might Not Receive Additional Doses, United States, 2012

Completion rates of the human papillomavirus (HPV) vaccine series among U.S. adolescents are below public health targets. We explored parent-reported reasons for their children's non-completion of the HPV vaccine series using a nationally representative online survey of parents of children aged 9-17 years, fielded in October 2012. Among the 1,653 parents who responded, the proportion reporting that their child would definitely continue with the HPV vaccine series among those who had started the series ranged from 28% to 54%. The most common reason cited by parents for non-completion of the series was their child's fear of needles, followed by lack of awareness about additional doses and safety concerns. These findings demonstrate the need to encourage adoption of strategies addressing needle fears, utilize reminders for parents about subsequent doses, and emphasize recent HPV vaccine safety data in discussions with parents.

Prenatal bisphenol a exposure and dysregulation of infant hypothalamic-pituitary-adrenal axis function: findings from the APrON cohort study

BACKGROUND

Animal models show that prenatal bisphenol A (BPA) exposure leads to sexually dimorphic disruption of the neuroendocrine system in offspring, including the hypothalamic-pituitary-adrenal (HPA) neuroendocrine system, but human data are lacking. In humans, prenatal BPA exposure is associated with sex-specific behavioural problems in children, and HPA axis dysregulation may be a biological mechanism. The objective of the current study was to examine sex differences in associations between prenatal maternal urinary BPA concentration and HPA axis function in 3 month old infants.

METHODS

Mother-infant pairs (n = 132) were part of the Alberta Pregnancy Outcomes and Nutrition study, a longitudinal birth cohort recruited (2010-2012) during pregnancy. Maternal spot urine samples collected during the 2nd trimester were analyzed for total BPA and creatinine. Infant saliva samples collected prior to and after a blood draw were analyzed for cortisol. Linear growth curve models were used to characterize changes in infant cortisol as a function of prenatal BPA exposure.

RESULTS

Higher maternal BPA was associated with increases in baseline cortisol among females (β = 0.13 log μg/dL; 95% CI: 0.01, 0.26), but decreases among males (β = -0.22 log μg/dL; 95% CI: -0.39, -0.05). In contrast, higher BPA was associated with increased reactivity in males (β = .30 log μg/dL; 95% CI: 0.04, 0.56) but decreased reactivity in females (β = -0.15 log μg/dL; 95% CI: -0.35, 0.05). Models adjusting for creatinine yielded similar results.

CONCLUSIONS

Prenatal BPA exposure is associated with sex-specific changes in infant HPA axis function. The biological plausibility of these findings is supported by their consistency with evidence in rodent models. Furthermore, these data support the hypotheses that sexually dimorphic changes in children's behaviour following prenatal BPA exposure are mediated by sexually dimorphic changes in HPA axis function.

IV Versus Subcutaneous Enoxaparin in Critically Ill Infants and Children: Comparison of Dosing, Anticoagulation Quality, Efficacy, and Safety Outcomes

OBJECTIVE

Subcutaneous enoxaparin is the mainstay anticoagulant in critically ill pediatric patients although it poses several challenges in this patient population. Enoxaparin infused IV over 30 minutes represents an attractive alternative, but there is limited experience with this route of administration in children. In this study, we assess dosing, anticoagulation quality, safety, and clinical efficacy of IV enoxaparin compared to subcutaneous enoxaparin in critically ill infants and children.

DESIGN

Retrospective single-center study comparing dosing, anticoagulation quality, safety, and clinical efficacy of two different routes of enoxaparin administration (IV vs subcutaneous) in critically ill infants and children. Key outcome measures included dose needed to achieve target antifactor Xa levels, time required to achieve target antifactor Xa levels, proportion of patients achieving target anticoagulation levels on initial dosing, number of dose adjustments, duration spent in the target antifactor Xa range, anticoagulation-related bleeding complications, anticoagulation failure, and radiologic response to anticoagulation.

SETTING

Tertiary care pediatric hospital.

PATIENTS

All children admitted to the cardiac ICU, PICU, or neonatal ICU who were prescribed enoxaparin between January 2014 and March 2016 were studied.

INTERVENTIONS

One hundred ten patients were identified who had received IV or subcutaneous enoxaparin and had at least one postadministration peak antifactor Xa level documented.

MEASUREMENTS AND MAIN RESULTS

Of the 139 courses of enoxaparin administered, 96 were therapeutic dose courses (40 IV and 56 subcutaneous) and 43 were prophylactic dose courses (20 IV and 23 subcutaneous). Dosing, anticoagulation quality measurements, safety, and clinical efficacy were not significantly different between the two groups.

CONCLUSIONS

Our study suggests that anticoagulation with IV enoxaparin infused over 30 minutes is a safe and an equally effective alternative to subcutaneous enoxaparin in critically ill infants and children.

Effects of Rapid Vaccine Injection Without Aspiration and Applying Manual Pressure Before Vaccination on Pain and Crying Time in Infants

AIM

To compare effects of rapid injection without aspiration and 10-second manual pressure before injection on pain severity and crying time in 4- to 6-month-old infants given the vaccine DTaP/IPV/Hib.

METHODS

This is a randomized double-blind controlled study. The study population included all the infants presenting for DTaP/IPV/Hib to two family health centers between April and August in 2015. The study sample included 128 infants based on confidence interval of 95% and statistical power of 80%. The sample was divided into four groups: manual pressure, rapid injection without aspiration, manual pressure combined with rapid injection without aspiration, and control groups. There were 32 infants in each group. Gender was adjusted in all groups. Stratified and block randomizations were used.

RESULTS

Pain severity scores and crying time during and after the injections were significantly lower in the three intervention groups than in the control group (p = .001). The lowest increase in the mean heart rate during and after the injections occurred in the rapid injection without aspiration group (p < .05). In addition, the mean oxygen saturation before, during and after the injections was significantly lower in this group than in the other groups (p < .05). However, two infants in the rapid injection without aspiration group had low oxygen saturation levels starting before the injections. In fact, mean oxygen saturations did not change across time. This suggests that lower oxygen saturation in the rapid injection without aspiration group cannot be due to vaccines or the techniques used.

LINKING EVIDENCE TO ACTION

Manual pressure and rapid injection without aspiration are effective and useful in relief of pain and reduction of crying time due to vaccine injections in 4- to 6-month-old infants.

Using quality improvement methods to increase use of pain prevention strategies for childhood vaccination

AIM

To increase evidence-based pain prevention strategy use during routine vaccinations in a pediatric primary care clinic using quality improvement methodology.

METHODS

Specific intervention strategies (i.e., comfort positioning, nonnutritive sucking and sucrose analgesia, distraction) were identified, selected and introduced in three waves, using a Plan-Do-Study-Act framework. System-wide change was measured from baseline to post-intervention by: (1) percent of vaccination visits during which an evidence-based pain prevention strategy was reported as being used; and (2) caregiver satisfaction ratings following the visit. Additionally, self-reported staff and caregiver attitudes and beliefs about pain prevention were measured at baseline and 1-year post-intervention to assess for possible long-term cultural shifts.

RESULTS

Significant improvements were noted post-intervention. Use of at least one pain prevention strategy was documented at 99% of patient visits and 94% of caregivers were satisfied or very satisfied with the pain prevention care received. Parents/caregivers reported greater satisfaction with the specific pain prevention strategy used [t(143) = 2.50, P≤ 0.05], as well as greater agreement that the pain prevention strategies used helped their children’s pain [t(180) = 2.17, P≤ 0.05] and that they would be willing to use the same strategy again in the future [t(179) = 3.26, P≤ 0.001] as compared to baseline. Staff and caregivers also demonstrated a shift in attitudes from baseline to 1-year post-intervention. Specifically, staff reported greater agreement that the pain felt from vaccinations can result in harmful effects [2.47 vs 3.10; t(70) = -2.11, P≤ 0.05], less agreement that pain from vaccinations is “just part of the process” [3.94 vs 3.23; t(70) = 2.61, P≤ 0.05], and less agreement that parents expect their children to experience pain during vaccinations [4.81 vs 4.38; t(69) = 2.24, P≤ 0.05]. Parents/caregivers reported more favorable attitudes about pain prevention strategies for vaccinations across a variety of areas, including safety, cost, time, and effectiveness, as well as less concern about the pain their children experience with vaccination [4.08 vs 3.26; t(557) = 6.38, P≤ 0.001], less need for additional pain prevention strategies [3.33 vs 2.81; t(476) = 4.51, P≤ 0.001], and greater agreement that their doctors’ office currently offers pain prevention for vaccinations [3.40 vs 3.75; t(433) = -2.39, P≤ 0.05].

CONCLUSION

Quality improvement methodology can be used to help close the gap in implementing pain prevention strategies during routine vaccination procedures for children.

Comparative Survey of Holding Positions for Reducing Vaccination Pain in Young Infants

Background. Infant holding position may reduce vaccination pain. However, the optimal position for young infants remains controversial. Objectives. To compare the effectiveness of holding infants in the supine position and the effectiveness of holding infants in upright position for relieving acute pain from vaccine injection. Methods. This prospective cohort study enrolled 6-12-week-old healthy infants. We examined infant pain responses by evaluating the following three categories: (1) crying, (2) irritability, and (3) facial expression. Results. In total, 282 infants were enrolled, with 103 and 179 held in the supine and upright positions, respectively. At 30 s after vaccination, the infants in the supine position showed a larger decrease in crying (p < 0.001), irritability (p = 0.002), and pained facial expression (p = 0.001) than did those in the upright position. However, there was no significant difference in pain response between two groups at 180 s after intervention. Conclusion. In 2-month-old infants, the supine position may reduce acute pain more effectively than does the upright position. Our findings provide a clinical strategy for relieving vaccination pain in young infants.

Comparison of iatrogenic pain between rotavirus vaccination before and after vaccine injection in 2-month-old infants

Oral rotavirus vaccine (RV) administration in conjunction with other injectable vaccines has been used worldwide. However, whether the sequence of RV administration is associated with the reduction of injection-induced pain remains unclear.

In this randomized controlled trial, we enrolled 6–12-wk-old healthy infants. The pain response of the infants was scored on the basis of their crying, irritability, facial expression, gagging and distress. A multivariate logistic regression model was used to compare the pain response after adjustment for possible confounders.

We enrolled 352 infants, of whom 176 infants received RV before injection (experimental group) and 176 infants received an RV after injection (comparison group). Sex, number of injections, main caregiver, feeding type, and RV type did not differ significantly between the 2 groups. Multivariate regression analyses showed that, at 30 s after the intervention, the episode of gagging was more frequent in the comparison group than in the experimental group (p = 0.004). At 180 s after the intervention, the infants cried more often in the comparison group (p < 0.001). Furthermore, the infants in the experimental group more often relaxed (p < 0.001), rested quietly (p = 0.001), and were smiling (p = 0.001) than did those in the comparison group.

Our results indicate that compared with oral RV administration after injection, oral RV administration before injection is more effective in reducing injection-induced pain in 2-mo-old infants. The findings can provide a clinical strategy for relieving pain from vaccination in young infants.

Effectiveness of ShotBlocker for Immunization Pain in Full-Term Neonates: A Randomized Controlled Trial

Nonpharmacologic strategies exist to manage procedural pain in healthy newborn infants. The aim of this prospective randomized controlled trial (RCT) was to examine the efficacy of ShotBlocker for managing injection pain associated with the first intramuscular hepatitis B vaccine given to healthy full-term neonates. This randomized controlled trial study was conducted in a private university hospital in Istanbul, Turkey, in which 100 healthy term neonates were randomly assigned to either a ShotBlocker (n = 50) or control group (n = 50). The Neonatal Infant Pain Scale scores of the neonates in the ShotBlocker and control groups were compared before, during, and after the injections, and the physiological parameters were compared before and after the procedure. The pain scores of the neonates during (ShotBlocker group: 1.64 ± 0.80; control group: 2.96 ± 0.73) and after (ShotBlocker group: 0.74 ± 0.66; control group: 1.42 ± 0.76) the injection procedure were lower in the ShotBlocker group than in the control group (P = .000). The postinjection heart rate in the infants in the ShotBlocker group (145.02 ± 13.50) was found to be lower than in those for whom ShotBlocker was not used (150.24 ± 13.36) (P = .05). The use of ShotBlocker during the hepatitis B vaccine in term neonates is effective in reducing the acute pain.

Evaluation of Vaccines Injection Order on Pain Score of Intramuscular Injection of Diphtheria, Whole Cell Pertussis and Tetanus Vaccine

OBJECTIVE

To determine, whether or not intramuscular injection of diphtheria, pertussis and tetanus (DwPT) vaccine should be given first and subcutaneous injection of measles, mumps and rubella (MMR) thereafter or vice versa and can this cause less pain of DwPT vaccine injection.

METHODS

In a randomized parallel group clinical trial, seventy 18-mo-old healthy children who were referred for routine vaccination to Akbari Health Care Center, Yazd, Iran from September 2014 through March 2015 were randomly allocated to two groups to receive DwPT and then MMR vaccines or MMR first, and then DwPT. Primary outcomes included pain score during DwPT injection, pain score during MMR injection, overall pain score of vaccination and obtaining a pain score of less than three during DwPT injection. Pain scores were assessed based on Modified Behavioral Pain Scale. Secondary outcome was crying duration during DwPT injection.

RESULTS

Thirty seven girls and 33 boys were evaluated in two groups. Pain scores of DwPT and MMR injections, the frequency of pain score obtained to be less than three during DwPT injection and the crying duration were not different in both groups. But, overall pain score of vaccination was lower when subcutaneous injection of MMR vaccine was given before intramuscular injection of DwPT vaccine. (14.23 ± 1.35 vs. 15.61 ± 2.65; P = 0.04).

CONCLUSIONS

Overall pain score of vaccination in multiple vaccine injection at the same visit might be reduced if subcutaneous vaccine is injected before intramuscular one.

ABM Clinical Protocol #23: Nonpharmacological Management of Procedure-Related Pain in the Breastfeeding Infant, Revised 2016

A central goal of The Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. These guidelines are not intended to be all-inclusive, but to provide a basic framework for physician education regarding breastfeeding.

Breastfeeding for procedural pain in infants beyond the neonatal period

BACKGROUND

Randomised controlled trials (RCTs) show that breastfeeding newborn infants during painful procedures reduces pain. Mechanisms are considered to be multifactorial and include sucking, skin-to-skin contact, warmth, rocking, sound and smell of the mother, and possibly endogenous opiates present in the breast milk.

OBJECTIVES

To determine the effect of breastfeeding on procedural pain in infants beyond the neonatal period (first 28 days of life) up to one year of age compared to no intervention, placebo, parental holding, skin-to-skin contact, expressed breast milk, formula milk, bottle feeding, sweet-tasting solutions (e.g. sucrose or glucose), distraction, or other interventions.

SEARCH METHODS

We searched the following databases to 18 February 2016: the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library), MEDLINE including In-Process & Other Non-Indexed Citations (OVID), Embase (OVID), PsycINFO (OVID), and CINAHL (EBSCO); the metaRegister of Controlled Trials (mRCT), ClinicalTrials.gov (clinicaltrials.gov), and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) (apps.who.int/trialsearch/) for ongoing trials.

SELECTION CRITERIA

We included RCTs and quasi-RCTs involving infants aged 28 days postnatal to 12 months and receiving breastfeeding while undergoing a painful procedure. Comparators included, but were not limited to, oral administration of water, sweet-tasting solutions, expressed breast or formula milk, no intervention, use of pacifiers, positioning, cuddling, distraction, topical anaesthetics, and skin-to-skin care. Procedures included, but were not limited to: subcutaneous or intramuscular injection, venipuncture, intravenous line insertion, heel lance, and finger lance. We applied no language restrictions.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Two review authors independently considered trials for inclusion in the review, assessed risk of bias, and extracted data. The main outcome measures were behavioural or physiological indicators and composite pain scores, as well as other clinically important outcomes reported by the authors of included studies. We pooled data for the most comparable outcomes and where data from at least two studies could be included. We used mean difference (MD) with 95% confidence interval (CI), employing a random-effects model for continuous outcomes measured on the same scales. For continuous outcomes measured on different scales, we pooled standardised mean differences (SMDs) and associated 95% CIs. For dichotomous outcomes, we planned to pool events between groups across studies using risk ratios (RRs) and 95% CIs. However, as insufficient studies reported dichotomous outcomes, we did not pool such events. We assessed the evidence using GRADE and created a 'Summary of findings' table.

MAIN RESULTS

We included 10 studies with a total of 1066 infants. All studies were conducted during early childhood immunisation. As the breastfeeding intervention cannot be blinded, we rated all studies as being at high risk of bias for blinding of participants and personnel. We assessed nine studies as being at low risk of bias for incomplete outcome data. In addition, we rated nine studies as high risk for blinding of outcome assessment. We scored risk of bias related to random sequence generation, allocation concealment, and selective reporting as unclear for the majority of the studies due to lack of information.Our primary outcome was pain. Breastfeeding reduced behavioural pain responses (cry time and pain scores) during vaccination compared to no treatment, oral water, and other interventions such as cuddling, oral glucose, topical anaesthetic, massage, and vapocoolant. Breastfeeding did not consistently reduce changes in physiological indicators, such as heart rate. We pooled data for duration of cry from six studies (n = 547 infants). Breastfeeding compared to water or no treatment resulted in a 38-second reduction in cry time (MD -38, 95% CI -50 to -26; P < 0.00001). The quality of the evidence according to GRADE for this outcome was moderate, as most infants were 6 months or younger, and outcomes may be different for infants during their 12-month immunisation. We pooled data for pain scores from five studies (n = 310 infants). Breastfeeding was associated with a 1.7-point reduction in standardised pain scores (SMD -1.7, 95% CI -2.2 to -1.3); we considered this evidence to be of moderate quality as data were primarily from infants younger than 6 months of age. We could pool heart rate data following injections for only two studies (n = 186); we considered this evidence to be of low quality due to insufficient data. There were no differences between breastfeeding and control (MD -3.6, -23 to 16).Four of the 10 studies had more than two study arms. Breastfeeding was more effective in reducing crying duration or pain scores during vaccination compared to: 25% dextrose and topical anaesthetic cream (EMLA), vapocoolant, maternal cuddling, and massage.No included studies reported adverse events.

AUTHORS' CONCLUSIONS

We conclude, based on the 10 studies included in this review, that breastfeeding may help reduce pain during vaccination for infants beyond the neonatal period. Breastfeeding consistently reduced behavioural responses of cry duration and composite pain scores during and following vaccinations. However, there was no evidence that breastfeeding had an effect on physiological responses. No studies included in this review involved populations of hospitalised infants undergoing other skin-breaking procedures. Although it may be possible to extrapolate the review results to this population, further studies of efficacy, feasibility, and acceptability in this population are warranted.

Using YouTube to Disseminate Effective Vaccination Pain Treatment for Babies

BACKGROUND

Infant vaccinations are necessary for public health, but are painful, causing distress to the infant and caregivers. Breastfeeding and sucrose effectively reduce infants' pain during vaccinations, and these strategies are recommended in health care provider (HCP)-targeted education and vaccination pain guidelines. However studies show these strategies are infrequently used. YouTube is a popular medium to publicly share and watch videos, and many consumer posted YouTube videos show distressed infants being vaccinated with no pain treatment. The aims of this study were to evaluate the reach and impact of a consumer-targeted YouTube video demonstrating use of effective pain reduction strategies during infant vaccinations.

METHODS

A brief consumer-targeted video showing two infants being vaccinated was posted onto YouTube on October 2013. One infant was breastfed and another infant received sucrose by mouth before and during the injection. A link to a viewer survey was visible on a banner near the end of the video. An intensive strategically planned knowledge dissemination strategy using the media, social media and messages to professional organizations took place to promote the video. Data analysis of the viewer survey, YouTube analytics of the reach of the video in terms of number of views, country of viewers, and comments relating to the video took place 12 months after the video was posted.

RESULTS

Twelve months after posting, the video had 65,478views, 68 comments, 245 likes, 17 dislikes, and 90 shares. Average duration of viewer time was 65% of the video. The viewer survey was completed by 156 (0.24%) viewers; 90 (58%) answered as HCPs and 66 (42%) as parents. Survey results showed that the video was persuasive; intent to use or support breastfeeding or sucrose was high in both parents and HCPs after viewing the video. Comments posted were often emotional in nature, and were related to anti-vaccination (n = 26, 38%); effectiveness or positive personal experiences (n = 21, 32%); research team comments or promotion (n = 12, 18%); pro-vaccination (n = 6, 8%) and barriers to using breastfeeding or sucrose during vaccinations (n = 3, 4%).

CONCLUSION

The video posted onto YouTube demonstrating effective pain treatment during infant vaccinations was viewed by large numbers of people around the world, however the response rate to the linked survey was extremely low. Using YouTube videos for knowledge dissemination has an extensive reach, however it is difficult to evaluate impact on behaviours and practices.

The effects of three different distraction methods on pain and anxiety in children

This study aims to investigate of three different distraction methods (distraction cards, listening to the music of cartoon and balloon inflation) on pain and anxiety relief of children during phlebotomy. This study is a prospective, randomized, and controlled trial. The sample consisted of 6 to 12 years old children who require blood tests. Children were randomized into four groups as the distraction cards, the music, the balloon inflation, and the control. Data were obtained by conducting interviews with the children, their parents, and the observer before and after the procedure. The pain levels of the children were assessed by the parent and observer reports as well as self-report using the Wong-Baker FACES. The anxiety levels of children were assessed by parent and observer reports using Children Fear Scale. One hundred and twenty children (mean age: 9.1 ± 1.6 years) were included. The self-reported procedural pain levels showed significant differences among the study groups (p = .040). The distraction card group (2.33 ± 3.24) had significantly lower pain levels (p = .057) than the control group (4.53 ± 3.23). The procedural child anxiety levels reported by the observer showed a significant difference among the study groups (p = .032). All the forms of distraction significantly reduced pain and anxiety perception.

Comparison of effect of kangaroo mother care, breastfeeding and swaddling on Bacillus Calmette-Guerin vaccination pain score in healthy term neonates by a clinical trial

BACKGROUND/AIM

The purpose of this research was to compare the analgesic effect of kangaroo mother care (KMC), breastfeeding and swaddling in Bacillus Calmette-Guerin (BCG) vaccination in term neonates.

METHODS

In a randomized 120 healthy term neonates who received routine BCG vaccination in the first day of their life are distributed into three groups. In group 1, neonates breastfed two minutes before, during and one minute after BCG vaccination. In group 2, neonates received KMC 10 minutes before, during and one minute after vaccination and in group 3, they were swaddled 10 minutes before, during and one minute after vaccination. Primary outcomes included pain score during, one minute and two minutes after BCG vaccination and obtaining pain score of less than three during vaccination .

RESULTS

Pain scores during, one minute and two minutes after vaccination in group 1 were lower than in groups 2 and 3. Group 1 had higher success rate in painless vaccination and had lower crying duration in comparison to another groups (p < 0.05) Conclusion: Breastfeeding was more effective than KMC and swaddling in reduction of BCG vaccination pain in healthy term neonates.

A Prospective Randomized Controlled Trial of Nonpharmacological Pain Management During Intravenous Cannulation in a Pediatric Emergency Department

OBJECTIVES

Intravenous (IV) cannulation is commonly performed in pediatric emergency departments (EDs). The busy ED environment is often not conducive to conventional nonpharmacological pain management. This study assessed the use of Ditto (Diversionary Therapy Technologies, Brisbane, Australia), a handheld electronic device which provides procedural preparation and distraction, as a means of managing pain and distress during IV cannulation performed in the pediatric ED.

METHODS

A randomized controlled trial with 98 participants, aged 3 to 12 years, was conducted in a pediatric ED. Participants were recruited and randomized into 5 intervention groups as follows: (1) Standard Distraction, (2) PlayStation Portable Distraction, (3) Ditto Distraction, (4) Ditto Procedural Preparation, and (5) Ditto Preparation and Distraction. Children's pain and distress levels were assessed via self-reports and observational reports by caregivers and nursing staff across the following 3 time points: (1) before, (2) during, and (3) after IV cannulation.

RESULTS

Caregivers and nursing staff reported significantly reduced pain and distress levels in children accessing the combined preparation and distraction Ditto protocol, as compared to standard distraction (P ≤ 0.01). This intervention also saw the greatest reduction in pain and distress as reported by the child.

CONCLUSIONS

Caregiver reports indicate that using the combined Ditto protocol was most effective in reducing children's pain experiences while undergoing IV cannulation in the ED. The use of Ditto offers a promising opportunity to negotiate barriers to the provision of nonpharmacological approaches encountered in the busy ED environment, and provide nonpharmacological pain-management interventions in pediatric EDs.

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.

Seriously clowning: Medical clowning interaction with children undergoing invasive examinations in hospitals

This qualitative study examined the subjective experience of children undergoing an invasive examination in the hospital when accompanied by a medical clown. In-depth semi-structured interviews were conducted with nine such children and nine of their accompanying parents. The children were patients in two outpatient departments (Pediatric Gastroenterology and a Center for the Sexually Abused) in a hospital in Israel. Interviews were coded thematically using an Atlas.ti software program. Analysis of the interviews indicated that the intervention of the clown positively changed the children's perceptions of the hospital, of experiencing the examination, and of their life narrative. Medical clowns thus appear to be a central, meaningful, and therapeutic source for children undergoing invasive examinations in hospital, as well as for their parents. Therefore, it may be advisable to incorporate medical clowns as an integral part of medical teams performing invasive procedures and to include the clowns in all stages of the hospital visit.

Effect of flick application on pain level and duration of crying during infant vaccination

BACKGROUND

The aim of the research is to determine the effect of flick application to reduce pain on pain level and duration of crying during vaccination.

METHOD

This research was carried out on one-month-old babies in a family health center between March and June 2015. The babies coming for the second dose of Hepatitis B vaccine were divided into experiment and control groups. The babies in experiment group were flicked just before they were vaccinated. On the other hand, the babies in control group were vaccinated in usual way, with no other application. The pain level of babies in both groups was determined using "Neonatal Infant Pain Scale". In addition, babies' duration of crying was recorded.

RESULTS

In the study, it was detected that there was not a significant difference between pain score averages of babies in experiment and control groups (p > 0.05) before the application, however a significant difference in pain score average was detected during the application (p < 0.01) and after the application (p < 0.001). Babies' duration of crying was compared and it was determined that babies in experiment group cried for shorter period, but no relevance was found (p > 0.05).

CONCLUSIONS

Flick application at vaccination area could be used to reduce pain during vaccination at babies.

Publicly available online educational videos regarding pediatric needle pain: a scoping review

OBJECTIVES

The objectives of this scoping review were to: (1) identify publicly available educational videos on needle pain management; and (2) evaluate the content of these videos.

METHODS

Reviewers screened publicly available educational videos on pediatric needle pain management available on YouTube and Google using a broad-based search strategy. Videos were categorized using the CRAAP Test: Current, Relevant, from a trustworthy source (Authority), Accurate and evidence-based, and for what Purpose does the source exist.

RESULTS

Twenty-five relevant, educational videos were identified. The intended audience for most videos was parents (n=16, 64%), followed by clinicians (n=6, 24%) and children (n=3, 12%). Common examples of needle pain included immunizations or IV insertion, with interventions appropriate for infants through school-aged children. The most frequently described techniques were parent-guided distraction and behavioral factors such as comfort holds and parent demeanor. Most videos were Current (96%), Relevant (100%), created by a trustworthy source: Authority (76%), and all were Accurate, with Purpose relating to needle pain management. None of the videos addressed the unique needs of children with a preexisting diagnosis of needle phobia.

DISCUSSION

Publicly available educational videos offer clinicians, parents, and children evidence-based techniques to manage pediatric needle pain. Further evaluation is needed to determine whether this form of education meets the needs of target audiences and whether this type of content can lead to improved management of pediatric needle pain.

An Evidence-Based Approach to Minimizing Acute Procedural Pain in the Emergency Department and Beyond

BACKGROUND

Painful procedures are common in the ED setting and beyond. Although these procedures are often essential to patient management, they can also be distressing for children, parents, and health providers. As such, it is imperative that effective pain and anxiety-minimizing strategies be used consistently in all settings where painful procedures take place for children.

OBJECTIVES

This review article aims to provide a summary of several strategies, which are supported by definitive and systematically reviewed evidence, that can be implemented alone or in combination to reduce procedural pain and anxiety for children in the ED and beyond.

RESULTS

For neonates, breastfeeding, nonnutritive sucking, swaddling, and sucrose administration have all been shown to decrease pain during painful interventions. For neonates, venipuncture is much less painful than heel lance for blood draws. For infants, there is some support for sucrose use. For infants and older children, there is strong evidence for distraction techniques. In addition, the use of fast-acting topical anesthetic creams as an alternative or adjunct to infiltrating anesthetic before laceration repair or vascular access/venipuncture is recommended. Further, buffering of lidocaine can decrease pain during injection. Lastly, if a laceration is amenable to the use of tissue adhesive, this should be preferentially used.

CONCLUSIONS

In summary, there currently remains a knowledge-to-practice gap in the treatment of children's procedure-related pain. This article has identified multiple age-specific methods to improve the treatment of procedural pain. These simple interventions can improve the care provided to ill and injured children.

The Assessment and Non-Pharmacologic Treatment of Procedural Pain From Infancy to School Age Through a Developmental Lens: A Synthesis of Evidence With Recommendations

The 2011 IOM report stated that pain management in children is often lacking especially during routine medical procedures. The purpose of this review is to bring a developmental lens to the challenges in assessment and non-pharmacologic treatment of pain in young children.

METHOD

A synthesis of the findings from an electronic search of PubMed and the university library using the keywords pain, assessment, treatment, alternative, complementary, integrative, infant, toddler, preschool, young, pediatric, and child was completed. A targeted search identified additional sources for best evidence.

RESULTS

Assessment of developmental cues is essential. For example, crying, facial expression, and body posture are behaviors in infancy that indicate pain: however in toddlers these same behaviors are not necessarily indicative of pain. Preschoolers need observation scales in combination with self-report while for older children self-report is the gold standard. Pain management in infants includes swaddling and sucking. However for toddlers, preschoolers and older children, increasingly sophisticated distraction techniques such as easily implemented non-pharmacologic pain management strategies include reading stories, watching cartoons, or listening to music.

DISCUSSION

A developmental approach to assessing and treating pain is critical. Swaddling, picture books, or blowing bubbles are easy and effective when used at the appropriate developmental stage and relieve both physical and emotional pain. Untreated pain in infants and young children may lead to increased pain perception and chronic pain in adolescents and adults. Continued research in the non-pharmacological treatment of pain is an important part of the national agenda.

Non-pharmacological management of infant and young child procedural pain

BACKGROUND

Infant acute pain and distress is commonplace. Infancy is a period of exponential development. Unrelieved pain and distress can have implications across the lifespan.  This is an update of a previously published review in the Cochrane Database of Systematic Reviews, Issue 10 2011 entitled 'Non-pharmacological management of infant and young child procedural pain'.

OBJECTIVES

To assess the efficacy of non-pharmacological interventions for infant and child (up to three years) acute pain, excluding kangaroo care, and music. Analyses were run separately for infant age (preterm, neonate, older) and pain response (pain reactivity, immediate pain regulation). 

SEARCH METHODS

For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 2 of 12, 2015), MEDLINE-Ovid platform (March 2015), EMBASE-OVID platform (April 2011 to March 2015), PsycINFO-OVID platform (April 2011 to February 2015), and CINAHL-EBSCO platform (April 2011 to March 2015). We also searched reference lists and contacted researchers via electronic list-serves. New studies were incorporated into the review. We refined search strategies with a Cochrane-affiliated librarian. For this update, nine articles from the original 2011 review pertaining to Kangaroo Care were excluded, but 21 additional studies were added.

SELECTION CRITERIA

Participants included infants from birth to three years. Only randomised controlled trials (RCTs) or RCT cross-overs that had a no-treatment control comparison were eligible for inclusion in the analyses. However, when the additive effects of a non-pharmacological intervention could be assessed, these studies were also included. We examined studies that met all inclusion criteria except for study design (e.g. had an active control) to qualitatively contextualize results. There were 63 included articles in the current update.

DATA COLLECTION AND ANALYSIS

Study quality ratings and risk of bias were based on the Cochrane Risk of Bias Tool and GRADE approach. We analysed the standardized mean difference (SMD) using the generic inverse variance method.

MAIN RESULTS

Sixty-three studies, with 4905 participants, were analysed. The most commonly studied acute procedures were heel-sticks (32 studies) and needles (17 studies). The largest SMD for treatment improvement over control conditions on pain reactivity were: non-nutritive sucking-related interventions (neonate: SMD -1.20, 95% CI -2.01 to -0.38) and swaddling/facilitated tucking (preterm: SMD -0.89; 95% CI -1.37 to -0.40). For immediate pain regulation, the largest SMDs were: non-nutritive sucking-related interventions (preterm: SMD -0.43; 95% CI -0.63 to -0.23; neonate: SMD -0.90; 95% CI -1.54 to -0.25; older infant: SMD -1.34; 95% CI -2.14 to -0.54), swaddling/facilitated tucking (preterm: SMD -0.71; 95% CI -1.00 to -0.43), and rocking/holding (neonate: SMD -0.75; 95% CI -1.20 to -0.30). Fifty two of our 63 trials did not report adverse events. The presence of significant heterogeneity limited our confidence in the findings for certain analyses, as did the preponderance of very low quality evidence.

AUTHORS' CONCLUSIONS

There is evidence that different non-pharmacological interventions can be used with preterms, neonates, and older infants to significantly manage pain behaviors associated with acutely painful procedures. The most established evidence was for non-nutritive sucking, swaddling/facilitated tucking, and rocking/holding. All analyses reflected that more research is needed to bolster our confidence in the direction of the findings. There are significant gaps in the existing literature on non-pharmacological management of acute pain in infancy.

Procedural Preparation and Support as a Standard of Care in Pediatric Oncology

Youth with cancer undergo many repeated and invasive medical procedures that are often painful and highly distressing. A systematic review of published research since 1995 identified 65 papers (11 review articles and 54 empirical studies) that investigated preparatory information and psychological interventions for a variety of medical procedures in pediatric cancer. Distraction, combined cognitive-behavioral strategies, and hypnosis were identified as effective for reducing child pain and increasing child coping. Low- to high-quality evidence informed strong recommendations for all youth with cancer to receive developmentally appropriate preparatory information and psychological intervention for invasive medical procedures.

Caregiver Soothing Behaviors After Immunization and Infant Attachment: A Longitudinal Analysis

OBJECTIVES

There were 2 primary objectives to the current study: (1) to relate caregiver behavior trajectories across immunization appointments over the first year of life to subsequent infant attachment and (2) to relate caregiver behavior trajectories within each immunization appointment over the first year of life to subsequent infant attachment.

METHOD

A subsample of 130 caregivers and their infants were recruited from a sample of 760 caregivers who were part of an ongoing longitudinal cohort that videotaped infants' 2-, 4-, 6-, and 12-month immunization appointments. This subsample of caregivers and their infants (n = 130) were invited to participate in an assessment of attachment when infants were between 12 and 18 months of age at the local children's hospital.

RESULTS

Caregiver proximal soothing behaviors were the only caregiver behaviors postimmunization that were related to subsequent infant attachment. Higher frequencies of caregiver proximal soothing at 12 months were related to infants' organized attachment, whereas steeper decreases in proximal soothing across the first year were associated with disorganized infant attachment. In addition, when caregivers engaged in proximal soothing for longer after their 12 month olds' immunizations, these infants were more likely to be secure or organized in their attachment.

CONCLUSION

These results provide empirical support for the ecological validity of studying infant attachment in a pediatric pain context. The pediatric "well-baby" visit may provide a potential opportunity to feasibly integrate brief infant mental health screening and intervention.

Far From "Just a Poke": Common Painful Needle Procedures and the Development of Needle Fear

BACKGROUND

Vaccine injections are the most common painful needle procedure experienced throughout the lifespan. Many strategies are available to mitigate this pain; however, they are uncommonly utilized, leading to unnecessary pain and suffering. Some individuals develop a high level of fear and subsequent needle procedures are associated with significant distress.

OBJECTIVE

The present work is part of an update and expansion of a 2009 knowledge synthesis to include the management of vaccine-related pain across the lifespan and the treatment of individuals with high levels of needle fear. This article will provide a conceptual foundation for understanding: (a) painful procedures and their role in the development and maintenance of high levels of fear; (b) treatment strategies for preventing or reducing the experience of pain and the development of fear; and (c) interventions for mitigating high levels of fear once they are established.

RESULTS

First, the general definitions, lifespan development and functionality, needle procedure-related considerations, and assessment of the following constructs are provided: pain, fear, anxiety, phobia, distress, and vasovagal syncope. Second, the importance of unmitigated pain from needle procedures is highlighted from a developmental perspective. Third, the prevalence, course, etiology, and consequences of high levels of needle fear are described. Finally, the management of needle-related pain and fear are outlined to provide an introduction to the series of systematic reviews in this issue.

DISCUSSION

Through the body of work in this supplement, the authors aim to provide guidance in how to treat vaccination-related pain and its sequelae, including high levels of needle fear.

Pharmacological and Combined Interventions to Reduce Vaccine Injection Pain in Children and Adults: Systematic Review and Meta-Analysis

BACKGROUND

This systematic review assessed the effectiveness and safety of pharmacotherapy and combined interventions for reducing vaccine injection pain in individuals across the lifespan.

DESIGN/METHODS

Electronic databases were searched for relevant randomized and quasi-randomized controlled trials. Self-reported pain and fear as well as observer-rated distress were critically important outcomes. Data were combined using standardized mean difference (SMD) or relative risk with 95% confidence intervals (CI).

RESULTS

Fifty-five studies that examined breastfeeding (which combines sweet-tasting solution, holding, and sucking), topical anesthetics, sweet-tasting solutions (sucrose, glucose), vapocoolants, oral analgesics, and combination of 2 versus 1 intervention were included. The following results report findings of analyses of critical outcomes with the largest number of participants. Compared with control, acute distress was lower for infants breastfed: (1) during vaccination (n=792): SMD -1.78 (CI, -2.35, -1.22) and (2) before vaccination (n=100): SMD -1.43 (CI, -2.14, -0.72). Compared with control/placebo, topical anesthetics showed benefit on acute distress in children (n=1424): SMD -0.91 (CI, -1.36, -0.47) and self-reported pain in adults (n=60): SMD -0.85 (CI, -1.38, -0.32). Acute and recovery distress was lower for children who received sucrose (n=2071): SMD -0.76 (CI, -1.19, -0.34) or glucose (n=818): SMD -0.69 (CI, -1.03, -0.35) compared with placebo/no treatment. Vapocoolants reduced acute pain in adults [(n=185), SMD -0.78 (CI, -1.08, -0.48)] but not children. Evidence from other needle procedures showed no benefit of acetaminophen or ibuprofen. The administration of topical anesthetics before and breastfeeding during vaccine injections showed mixed results when compared with topical anesthetics alone. There were no additive benefits of combining glucose and non-nutritive sucking (pacifier) compared with glucose or non-nutritive sucking (pacifier) alone or breastfeeding and sucrose compared with breastfeeding or sucrose alone.

CONCLUSIONS

Breastfeeding, topical anesthetics, sweet-tasting solutions, and combination of topical anesthetics and breastfeeding demonstrated evidence of benefit for reducing vaccine injection pain in infants and children. In adults, limited data demonstrate some benefit of topical anesthetics and vapocoolants.

Psychological Interventions for Vaccine Injections in Children and Adolescents: Systematic Review of Randomized and Quasi-Randomized Controlled Trials

BACKGROUND

This systematic review evaluated the effectiveness of psychological interventions for reducing vaccination pain and related outcomes in children and adolescents.

DESIGN/METHODS

Database searches identified relevant randomized and quasi-randomized controlled trials. Data were extracted and pooled using established methods. Pain, fear, and distress were considered critically important outcomes.

RESULTS

Twenty-two studies were included; 2 included adolescents. Findings showed no benefit of false suggestion (n=240) for pain (standardized mean difference [SMD] -0.21 [-0.47, 0.05]) or distress (SMD -0.28 [-0.59, 0.11]), or for use of repeated reassurance (n=82) for pain (SMD -0.18 [-0.92, 0.56]), fear (SMD -0.18 [-0.71, 0.36]), or distress (SMD 0.10 [-0.33, 0.54]). Verbal distraction (n=46) showed reduced distress (SMD -1.22 [-1.87, -0.58]), but not reduced pain (SMD -0.27 [-1.02, 0.47]). Similarly, video distraction (n=328) showed reduced distress (SMD -0.58 [-0.82, -0.34]), but not reduced pain (SMD -0.88 [-1.78, 0.02]) or fear (SMD 0.08 [-0.25, 0.41]). Music distraction demonstrated reduced pain when used with children (n=417) (SMD -0.45 [-0.71, -0.18]), but not with adolescents (n=118) (SMD -0.04 [-0.42, 0.34]). Breathing with a toy (n=368) showed benefit for pain (SMD -0.49 [-0.85, -0.13]), but not fear (SMD -0.60 [-1.22, 0.02]); whereas breathing without a toy (n=136) showed no benefit for pain (SMD -0.27 [-0.61, 0.07]) or fear (SMD -0.36 [-0.86, 0.15]). There was no benefit for a breathing intervention (cough) in children and adolescents (n=136) for pain (SMD -0.17 [-0.41, 0.07]).

CONCLUSIONS

Psychological interventions with some evidence of benefit in children include: verbal distraction, video distraction, music distraction, and breathing with a toy.

Promoting Vaccine Confidence

Vaccine hesitancy incorporates a wide range of parental attitudes and behaviors surrounding vaccines. Ironically, the very success of the immunization program has fueled vaccine concerns; because vaccine-preventable diseases are no longer prevalent, attention has shifted to the safety and necessity of vaccines themselves. This article reviews some of the underlying themes of vaccine hesitancy as well as specific vaccine safety concerns. Strategies for discussing vaccines with concerned parents are also discussed.

Ethical Challenges in School-Based Immunization Programs for Adolescents: A Qualitative Study

OBJECTIVES

We investigated ethical issues in school-based immunization programs for adolescents and how they are addressed.

METHODS

We used qualitative methods and an ethnographic approach to observe 9 secondary schools on immunization days in South Australia in 2011; concurrently, we conducted 9 focus groups with female secondary school students, 6 semistructured interviews with parents, and 10 interviews with nurses and teachers. We explored ethical challenges from the perspective of these groups.

RESULTS

We identified ethical challenges for the delivery of adolescent immunization in a school-based setting in 3 main areas: informed consent, restrictions on privacy, and harm to students in the form of fear and anxiety.

CONCLUSIONS

We found areas in which the design and delivery of school-based immunization programs can be improved. Information about immunization should be provided in ways that are appropriate to young people and their parents, and privacy protections should be enhanced when possible. Involving young people in the design and delivery of programs would assist with making these improvements.

The Effects of Instrumental Touching on Infant Pain Perception and the Effects of Eutectic Mixture of Local Anesthetics (EMLA) on the Reduction of Pain

Background:

Premature infants, who have to spend the first week of their lives in neonatal intensive care units (NICUs), experience pain and stress in numerous cases, and they are exposed to many invasive interventions. The studies have shown that uncontrolled pain experienced during early life has negative and long-term side effects, such as distress, and such experiences negatively affect the development of the central nervous system

Objectives:

The purpose of the study was to examine the effects of touching on infant pain perception and the effects of eutectic mixture of local anesthetic (EMLA) on the reduction of pain.

Patients and Methods:

Data for the study were collected between March and August 2012 from the neonatal clinic of a university hospital located in eastern Turkey. The population of the study consisted of premature infants who were undergoing treatment, completed the first month and who were approved for Hepatitis B vaccine. The study consisted of two experimental groups and one control group. Information forms, intervention follow-up forms, and Premature Infant Pain Profile (PIPP) were used to collect the data. EMLA cream was applied on the vastus lateralis muscles of the first experimental group before the vaccination. The second experimental group was vaccinated by imitation (placebo), without a needle tip or medicine. Vaccination was carried out using instrumental touch in this group. A routine vaccination was applied in the control group.

Results:

Mean pain scores of the group to which EMLA was applied were lower in a statistically significant way (P < 0.05) compared to the pain scores of the other groups. Moreover, it was determined that even though invasive intervention was not applied to the newborns, the touching caused them to feel pain just as in the placebo group (P < 0.005).

Conclusions:

The results demonstrated that EMLA was an effective method for reducing pain in premature newborns, and the use of instrumental touch for invasive intervention stimulated the pain perception in the newborns.

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.
