Effectiveness and tolerability of pharmacologic and combined interventions for reducing injection pain during routine childhood immunizations: Systematic review and meta-analyses

Local analgesia for the relief of pain in children undergoing venipuncture and intravenous cannulation: a systematic review and network meta-analysis

BACKGROUND

Venipuncture and intravenous cannulation are common procedures in hospitals that often cause pain, particularly in children. Despite the availability of various local analgesia methods to alleviate needle-associated pain, the most effective approach remains unknown. The objective of this study is to compare and rank the efficacy of different local analgesia methods in reducing pain in children undergoing venipuncture and intravenous cannulation.

METHOD

Six databases including PubMed, Embase, CINAHL, Scopus, Web of Science, and the Cochrane Library were searched from January 1,1990 to December 1,2024. The primary outcome is the self-reported pain. We assessed the certainty of the body of evidence from the NMA for the primary outcome based on CINeMA.

RESULT

40 RCTs consisting of 4481 children and 9 local analgesia methods were included in the analysis. Results showed that vapocoolant spray was no more effective than placebo or routine care in reducing needle-associated pain in children. Other interventions including EMLA cream, lidocaine cream, lidocaine iontophoresis, amethocaine, needle-free lidocaine injection system, EMLA patch, lidocaine/tetracaine heating patch and Buzzy produced greater pain reduction in children compared to placebo and routine care. Amethocaine was the most effective local analgesia method with the probability of 57.6% being the best, followed by Buzzy and lidocaine iontophoresis with the probability of 17.0% and 8.4%, respectively.

CONCLUSION

Most local analgesia methods were effective in relieving pain in children undergoing venipuncture and intravenous cannulation except vapocoolant spray which did not show greater pain reduction than placebo or routine care. Amethocaine, Buzzy and lidocaine iontophoresis are the top 3 local analgesia methods to relieve pain in children undergoing venipuncture and intravenous cannulation. However, due to the limited number of direct comparisons, interpretation of some results should be made with caution.

[Breastfeeding, an analgesic technique for painful care that can be used in rehabilitation?]

Pain management in infants is crucial during painful care. This work evaluates the effect of breastfeeding on procedural pain, measured by the Neonatal Infant Pain Scale score. A rapid review included nine randomized controlled trials (RCT) on PubMed, comparing breastfeeding with other techniques (maternal contact, sucrose, etc.). Breastfeeding significantly reduces pain compared with maternal contact, and is comparable in efficacy to sucrose. Despite methodological limitations, this simple and effective technique could be integrated into pain management in pediatric rehabilitation. Further studies are needed to clarify its benefits.

Cold and vibration for children undergoing needle-related procedures: A non-inferiority randomized clinical trial

The use of a rapid, easy-to-use intervention could improve needle-related procedural pain management practices in the context of the Emergency Department (ED). As such, the Buzzy device seems to be a promising alternative to topical anesthetics. The aim of this study was to determine if a cold vibrating device was non-inferior to a topical anesthetic cream for pain management in children undergoing needle-related procedures in the ED. In this randomized controlled non-inferiority trial, we enrolled children between 4 and 17 years presenting to the ED and requiring a needle-related procedure. Participants were randomly assigned to either the cold vibrating device or topical anesthetic (4% liposomal lidocaine; standard of care). The primary outcome was the mean difference (MD) in adjusted procedural pain intensity on the 0-10 Color Analogue Scale (CAS), using a non-inferiority margin of 0.70. A total of 352 participants were randomized (cold vibration device n = 176, topical anesthetic cream n = 176). Adjusted procedural pain scores' MD between groups was 0.56 (95% CI:-0.08-1.20) on the CAS, showing that the cold vibrating device was not considered non-inferior to topical anesthetic. The cold vibrating device was not considered non-inferior to the topical anesthetic cream for pain management in children during a needle-related procedure in the ED. As topical anesthetic creams require an application time of 30 min, cost approximately CAD $40.00 per tube, are underused in the ED setting, the cold vibrating device remains a promising alternative as it is a rapid, easy-to-use, and reusable device.

A Comparison of the Effects of Acupressure and Music on Venipuncture Pain Intensity in Children: A Randomized Controlled Clinical Trial

Pain from injections is common in children of all ages, and more than 90% of hospitalized children experience invasive and painful procedures such as venipuncture. In light of the complications associated with pain relief medications, nonpharmacological and complementary medicine approaches have gained attention. This study aims to compare the effects of acupressure and music on venipuncture pain intensity in children. This randomized controlled clinical trial involved 180 children aged 3-6 years who sought treatment at the Children's Medical Center Hospital Emergency Department at Tehran University of Medical Sciences, Iran. The children were randomly assigned to one of three groups: acupressure, music, or control. The interventions were given within 5 minutes, starting 3 minutes before the venipuncture and continuing until completion. The interventions included playing music through headphones and applying acupressure to the Hugo point. Venipuncture was carried out under identical conditions using an Angiocath 24G needle. Pain intensity was assessed using the Oucher scale. Data were analyzed using SPSS 24, employing the Kruskal-Wallis, chi-square, and Bonferroni pairwise comparison tests, with a significance level of 0.05. The mean pain intensity was 3.32 ± 1.44 in the music group, 4.82 ± 1.51 in the acupressure group, and 8.32 ± 1.10 in the control group. Pain intensity significantly differed among the three groups (p < 0.001). Specifically, pain intensity was lower in the music group compared to both the acupressure (p < 0.001) and control (p < 0.001) groups. Furthermore, pain intensity was lower in the acupressure group than in the control group (p < 0.001). Based on the results, music and acupressure methods effectively reduce pain intensity during venipuncture in children. Considering that music demonstrated a more pronounced effect in alleviating venipuncture pain than acupressure, the recommendation is to utilize music as a method of pain management during venipuncture in children. Iranian Registry of Clinical Trials, Trial No. IRCT20120109008665N15, was registered on 6 December 2021.

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

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

CONCLUSION

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

The certified child life specialist: A novel resource in the pediatric primary care clinic for managing children's pain during routine immunizations

This study evaluated the effect of the Certified Child Life Specialist (CCLS) on pediatric pain and pain management during routine immunization administration in the pediatric primary care clinic. Children 4-12 years of age (n = 125) presenting for a well child physical examination at a rural primary care clinic were selected to receive standard nursing care or standard nursing care plus CCLS support during routine immunization administration. Patient reported pain was measured using the Faces Pain Scale-Revised (FPS-R), and patient behavioral responses were measured during immunization administration using the Children's Emotional Manifestation Scale (CEMS). The performance of psychosocial interventions and administration of topical pain-relieving interventions were measured between both groups. CCLS support was associated with fewer negative emotional behaviors during immunization administration among 7- to 12-year-old children and a significantly higher provision of psychosocial interventions and topical pain-relieving interventions among all ages. This study demonstrates that the presence of a CCLS can increase the provision of psychosocial and pain-relieving interventions and reduce distress during immunization administration in a busy pediatric primary care clinic.

Optimizing Your Pediatric Office for Vaccine Confidence

Parents trust their pediatric clinicians for up-to-date information about vaccines. To reduce vaccine hesitancy, clinics must promote confidence by building trust, communicating clearly, using patient safety and infection control principles to reduce errors, and reducing missed opportunities by having a vaccination infrastructure that makes every visit a vaccine visit. Education and communication must be consistent among all staff and culturally competent to optimize vaccine confidence. Parents have a role in seeking reliable resources, raising concerns, and seeking trusted, evidence-based experts for vaccination conversations. Safe, effective vaccines are vital; however, vaccination, a complex operational process, prevents disease and saves lives.

Effect of coolant spray on rib fracture pain of geriatric blunt thoracic trauma patients: a randomized controlled trial

OBJECTIVE

This study aimed to evaluate the effectiveness of cryotherapy in elderly patients with rib fractures due to blunt thoracic trauma.

METHODS

In this prospective randomized controlled study, geriatric patients were assigned to groups to receive either coolant spray (n=51) or placebo spray (n=50). The visual analog scale scores of all patients were recorded before starting spray application (V0), as well as at 10th (V1), 20th (V2), 30th (V3), 60th (V4), 120th (V5), and 360th (V6) minute. The mean decreases in the visual analog scale scores were calculated.

RESULTS

The differences between V0 and V1, V0 and V2, V0 and V3, and V0 and V4 mean visual analog scale scores measured in the coolant spray group were found to be significantly higher (p<0.001). In V1, V2, V3, and V4 measurements, the incidence of "clinical effectiveness" in the coolant spray group was significantly higher than in the placebo group (p=0.001).

CONCLUSIONS

Coolant spray therapy can be used as a component of multimodal therapy to provide adequate analgesia due to rib fractures in geriatric patients.

Efficacy and safety of vapocoolant spray for vascular puncture in children and adults: A systematic review and meta-analysis

OBJECTIVE

The aim was to evaluate the effectiveness and safety of the vapocoolants for vascular puncture in children and adults.

METHOD

The search was carried out in PubMed, Web of Science, Embase and The Cochrane Library, from inception to March 2022. Randomized controlled trials comparing vapocoolants to control conditions for participants received intravenous cannulation or arterial puncture were included. Two reviewers independently performed selection of studies, data extraction, and assessment of risk of bias. The analysis was performed using fixed or random-effects model with mean differences or standardized mean difference and risk ratios.

RESULTS

A total of 25 studies involving 3143 participants were included. Compared with control conditions, vapocoolants may not decrease the pain of patients with arterial puncture (SMD = -0.36, 95% CI = -0.92 to -0.19, P = 0.20), but may more effectively relieve pain for adults received vein puncture (SMD = -0.65, 95% CI = -0.85 to -0.45, P < 0.00001). The application of vapocoolant increased the procedural difficulty of medical personnel (RR = 2.49, 95% CI = 1.62 to 3.84, P<0.000 1) and participants were more willing to use the spray in the future (RR = 1.88, 95% CI = 1.34 to 2.64, P = 0.0002). There was no significant difference for the first attempt success rate of the procedure and the occurrence of adverse events.

CONCLUSIONS

Vapocoolant spray may relieve pain in adults received vein puncture and cannot cause severe side effects, but is ineffective in children. It also had no effect on patients with arterial puncture. In addition, the application of spray increases procedural difficulties for medical professionals, but does not decrease first attempt success rate, and many patients would like to use the spray again for pain relief in the future. Thus, more rigorous and large-scale studies are needed to determine its effectiveness in vascular access.

Comparison of the Effect of EMLA™ Cream and the Valsalva Maneuver on Pain Severity during Vascular Needle Insertion in Hemodialysis Patients: A Controlled, Randomized, Clinical Trial

Background

Pain due to vascular needle insertion has been reported in 40-60% of hemodialysis (HD) patients. Evidence suggests that there is typically no single method for relieving the pain of inserting vascular needles in HD patients. This study aimed to compare the effectiveness of EMLA cream and Valsalva maneuver (VM) on pain severity during vascular needle insertion in HD patients.

Methods

This randomized, controlled, clinical trial was conducted on 90 patients undergoing hemodialysis in the hemodialysis unit of Kowsar Hospital, affiliated with Semnan University of Medical Sciences, in Semnan, Iran. Patients were selected via convenience sampling and were randomly assigned to one of the three groups (EMLA, VM, and control groups). For the patients in the EMLA group, 2.5 g of EMLA cream was applied 60 minutes before the start of dialysis. For patients in the VM group, a maneuver was performed for 16-20 seconds before the needle was inserted. Patients in the control group received only routine care without any additional interventions. The pain severity in the three groups was measured using the visual analog scale (VAS) two minutes after vascular needle insertion.

Results

The results showed that the mean pain severity during cannulation was 2.06 ± 2.19 in the EMLA group, 3.2 ± 30.42 in the VM group, and 6.20 ± 1.49 in the control group, suggesting a significant difference between the groups (P < 0.001). Pairwise comparison of the mean pain severity showed that it differed significantly in the EMLA and VM groups from the control group (P < 0.001), but no significant difference was found between the EMLA and VM groups (P=0.067).

Conclusion

According to the results, EMLA cream was as effective as VM in reducing the pain severity caused by arteriovenous fistula (AVF) cannulation. Therefore, the use of EMLA cream and VM is recommended for reducing the severity of AVF cannulation pain. Trial Registration.

The efficacy of vapocoolant spray for the improved tolerance of catheter pain in emergency patients

OBJECTIVES

This study aimed to determine if dogs and cats presenting as an emergency had improved tolerance of intravenous catheterisation following the application of vapocoolant spray when compared to a saline control.

MATERIALS AND METHODS

A randomised controlled trial of client-owned dogs and cats presenting as an emergency and requiring intravenous catheterisation was performed. Patient signalment and mentation score were recorded. All animals were restrained and had their fur clipped over the catheterisation site. They were then randomly allocated to either have a swab saturated with vapocoolant spray (treatment) or a swab saturated with saline (control) applied to the clipped area before intravenous catheterisation. The procedure was video recorded and a single blinded observer reviewed the recordings and assigned reaction scores (0 to 3) at four time points (initial restraint, limb handling, swab application and skin puncture).

RESULTS

Between October 2020 and January 2021, a total of 100 patients (79 dogs, 21 cats) were enrolled, with 50 in each group. No significant difference in species, age, breed, sex or mentation score was detected between the two groups. There was no significant difference in reaction scores between the groups at any time point with the exception of a significantly increased swab application reaction score in the treatment group compared to the control group.

CLINICAL SIGNIFICANCE

The indirect application of vapocoolant spray via a swab before catheterisation does not significantly reduce the reaction of dogs and cats to intravenous catheterisation in an emergency setting.

Analgesic effects of breast- and formula feeding during routine childhood immunizations up to 1 year of age

BACKGROUND

Data on analgesic effects of breast/formula milk sucking while receiving routine childhood immunizations are available only in early infancy, have rarely been compared in the same study, and are not accompanied by information on mothers' satisfaction/acceptance. Here we aimed to compare the analgesic effect of both methods vs. held-only controls up to 1 year of age, and verify mothers' satisfaction.

METHODS

Two to 12 months children subjected to vaccine were allocated into three groups: breastfed, formula-fed, and held-only controls. A video recording was performed to analyze pain parameters: crying latency/duration and specific scales [FLACC (Face, Legs, Activity, Cry, and Consolability), NIPS (Neonatal Infant Pain Scale)]. After the procedure, mothers filled in a satisfaction questionnaire.

RESULTS

One-hundred and sixty-two children were recruited: 54 breastfed, 35 formula fed, and 73 controls. Breastfed showed the longest crying latency, and together with formula fed, had the shortest duration and lowest pain scores. Most mothers appreciated not only the respective feeding-mediated pain mitigation method used, but also the simply-holding procedure. In all cases, they felt reassured, with an unexpected frequent underestimation of their child's pain during the shot.

CONCLUSIONS

The analgesic effect of breastfeeding during vaccination extends also to children >6 months old, and is obtained by formula too. Embracing the child may help to reassure mothers.

IMPACT

We confirmed the analgesic effect of breastfeeding during the vaccination procedures in early infancy. We show for the first time that this effect is extended also to children up to 1 year of age, and it may be obtained by formula feeding as well. Most mothers appreciated pain mitigation not only through feeding, but also the simply-holding procedure. In all cases, mothers felt reassured, with an unexpected frequent underestimation of their child' pain during the shot. The promotion of these easily feasible and well-accepted strategies should be further encouraged within health professionals during vaccination procedures.

The efficacy of administrating a sweet-tasting solution for reducing the pain related to dental injections in children: A randomized controlled trial

BACKGROUND

Anaesthetic injections are an unpleasant experience for children in the dental office. Oral intake of sweet substances by newborns has been shown to be effective in reducing pain.

AIM

The purpose of this study was to determine whether a prior administration of a sweet-tasting solution has an effect on dental injection pain.

DESIGN

A total of 56 healthy children needing bilateral maxillary primary canine extraction were included in this split-mouth randomized clinical trial. In the test side, dental injection (local infiltration) was applied after the patient received a sweet-tasting solution, while in the control side sterile water was administered. The patients' demographic characteristics, body mass index (BMI), and sweet taste preference were recorded. Pain perception during injection was measured using visual analogue scale (VAS) and sound, eye, body movement (SEM).

RESULTS

Mean VAS (28.30 ± 6.43) and SEM (2.14 ± 0.78) in the test side were lower than the control side (45.80 ± 7.17 and 2.95 ± 1.00). It was shown that higher BMI was associated with reduction in the analgesic effect, while the individual's tendency to sweetness increased pain reduction.

CONCLUSIONS

Sweet taste administration before dental injections in children helps to control the associated pain. This effect is influenced by the individual's sweet taste tendency and BMI.

Parent-Targeted Education Regarding Infant Pain Management Delivered During the Perinatal Period: A Scoping Review

All infants experience pain in early life from procedures. Parents recognize pain as a prevalent issue, reporting a strong desire for more information on infant pain. The aim of this study was to explore and map the current evidence of parent-targeted educational interventions about infant pain, delivered throughout the perinatal period. Records were identified in PubMed, CINAHL, EMBASE, and ERIC databases and hand searching recent publications in 3 relevant journals. Records in English that described or evaluated educational interventions on infant pain management aimed at parents during the perinatal period were eligible for review and those not related to pain or aimed at healthcare providers were excluded. Evaluation was completed following the Methodology for JBI Scoping Reviews and standardized critical appraisal instruments from the Joanna Briggs Institute. Initial search yielded 6946 records, with 9 included in analysis. Six studies were quantitative, 2 qualitative, and 1 mixed methods. Included interventions contained information about parent-led pain management strategies for infants in the neonatal intensive care unit (n = 4), full term (n = 4), or both (n = 1). Despite being an area of high concern for parents of newborns, few studies addressed parent-targeted education regarding infant pain. Future research examining the impact and efficacy of these interventions addressing parental and neonatal outcomes is warranted.

Vaccines Attitudes, Concerns, and Information Sources Reported by Parents of Young Children among North Palestinian Parents

Parental acceptance of routine childhood immunization is critical to protecting children's health, as high vaccination-coverage rates lead to decreased rates of vaccine-preventable diseases. However, to communicate effectively with parents about vaccines and vaccine-preventable diseases, it is necessary to assess their vaccine-related attitudes and concerns continually. Recently the Palestine Ministry of Health has recorded epidemics of measles and mumps. Poor compliance with vaccination has been attributed to multiple factors including physician inadequacy advocating for vaccination and public mistrust of vaccinations. As a result, this study was conducted to describe the vaccine-related attitudes, concerns, and information sources of North Palestinian parents of young children. A cross-sectional survey was conducted involving parents visiting emergency departments and primary health care centers from different North Palestinian hospitals and centers. 480 surveys were eligible and analyzed. The surveys revealed that although parental confidence in vaccine safety is high, several vaccine-related concerns, such as pain from vaccine administration and the number of vaccines given at once, were common among parents of young children. To maintain and improve the success of childhood vaccines in preventing disease, a holistic approach is needed to address parents' concerns in an ongoing manner. Listening and responding in ways and with resources that address specific questions and concerns could help parents make more informed vaccination decisions.

The effectiveness of the BuzzyⓇ device to reduce or prevent pain in children undergoing needle-related procedures: The results from a prospective, open-label, randomised, non-inferiority study

BACKGROUND

Pain from needle-related procedures in children can alter pain perception, increase pain sensitivity, and generate inappropriate pain responses. Currently pain management includes the use of lidocaine-containing patches, which is complicated to manage in a busy medical setting such as a vaccination centre. We assessed the Buzzy^Ⓡ device, which combines vibration and cold, to manage pain in children undergoing a needle-related procedure, compared to the standard lidocaine patch.

DESIGN

Prospective, open-label, non-inferiority trial.

SETTING

The vaccination centres of three university hospitals in France.

PARTICIPANTS

French speaking children aged 4-15 requiring a needle-related procedure (vaccination or venepuncture) were eligible. Principal exclusion criteria were allergy or sensitivity to the lidocaine patch.

METHODS

Children were randomly allocated (1:1) to use either the Buzzy^Ⓡ device or the lidocaine patch during the needle-related procedure. The lidocaine patch was applied to the puncture site for the hour prior to the intervention. The Buzzy^Ⓡ device was applied to the puncture site for 30 s and then moved 5 cm along the limb during the procedure. The refrigerated wings were detached if they bothered the child. The child assessed their pain using the validated Revised Faces Pain Scale. The revised faces pain scale comprised six facial expressions from 0, normal "no pain" to 10, a screaming face "severe pain" (2 points/face). The primary endpoint was the average pain score recorded by the child. The study aimed to test the non-inferiority of Buzzy^Ⓡ.

RESULTS

Overall 219 participants were randomised. The primary outcome was assessed in 215 children: 108 in the BUZZY group (43% asked for the refrigerated wings were de to be detatched before the end of the procedure) and 107 in the PATCH group. The baseline characteristics were similar between the study groups with an average age of 9 (range: 4.08-15.81). The average needle-related pain was 2.04 in the BUZZY group and 1.42 in the PATCH group. The average difference between the children's assessments in the groups was 0.62, thus faling to demonstrate non-inferiority.

CONCLUSIONS

Our study failed to show that the Buzzy^Ⓡ device was not inferior to the lidocaine patch in managing pain in children undergoing needle-related procedures.

The Opioid Wars-CON: The Risks of Opioids for Pain Management Outweigh the Benefits

The entire field of medicine, not just anesthesiology, has grown comfortable with the risks posed by opioids; but these risks are unacceptably high. It is time for a dramatic paradigm shift. If used at all for acute or chronic pain management, they should be used only after consideration and maximizing the use of nonopioid pharmacologic agents, regional analgesia techniques, and nonpharmacologic methods. Opioids poorly control pain, their intraoperative use may increase the risk of recurrence of some types of cancer, and they have a large number of both minor and serious side effects. Furthermore, there are a myriad of alternative analgesic strategies that provide superior analgesia, decrease recovery time, and have fewer side effects and risks associated with their use. In this article the negative consequences of opioid use for pain, appropriate alternatives to opioids for analgesia, and the available evidence in pediatric populations for both are described.

Comparison of the Effect of Massage and EMLA Cream on Children's Physiological Indices During Venipuncture: A Factorial Clinical Trial

PURPOSE

The aim of this study was to identify the effect of massage, EMLA cream, and the combination of these two methods on changes in physiological indices because of pain caused by intravenous line insertion in preschool children.

DESIGN

A four-group randomized nonblinded clinical trial with factorial design.

METHODS

In total, 140 eligible 3- to 6-year-old children entered the study in Tabriz Children's Hospital in 2017 and were randomly allocated to four groups (EMLA cream, massage, combination of the two, and control). Physiological responses were measured before and immediately after interventions in all groups. Data were collected and analyzed using SPSS version 19.

FINDINGS

Comparison of the physiological indices changes caused by pain between groups showed that changes in children's heart rate (HR) and respiratory rate (RR) in the EMLA group and in the combined-method group were statistically significant (P < .05). No significant differences were found in systolic blood pressure and oxygen saturation (SPo₂) between the four groups.

CONCLUSIONS

Results indicated that EMLA cream was more effective than massage and a combination of EMLA and massage in reducing an increase in the HR and RR caused by pain in children. Massage alone was not effective in significantly lowering the children's increased physiological indices such as the HR and RR, and it seems the effectiveness of massage is more noticeable in conjunction with EMLA cream.

Implementation Effectiveness of a Parent-Directed YouTube Video ("It Doesn't Have To Hurt") on Evidence-Based Strategies to Manage Needle Pain: Descriptive Survey Study

BACKGROUND

Despite the availability of high-quality evidence and clinical practice guidelines for the effective management of pediatric pain, this evidence is rarely used in practice for managing children's pain from needle procedures such as vaccinations. Parents are generally unaware of pain management strategies they can use with their children.

OBJECTIVE

This study aimed to develop, implement, and evaluate the implementation effectiveness of a parent-directed YouTube video on evidence-based strategies to manage needle pain in children.

METHODS

This was a descriptive study. Analytics were extracted from YouTube to describe video reach. A Web-based survey was used to seek parent and health care professional (HCP) feedback about the video. The 2-minute 18-second video was launched on YouTube on November 4, 2013. In the video, a 4-year-old girl tells parents what they should and should not do to help needles hurt less. The key evidence-based messages shared in the video were distraction, deep breathing, and topical anesthetic creams. A group of parents (n=163) and HCPs (n=278) completed the Web-based survey. Measures of reach included number of unique views, country where the video was viewed, sex of the viewer, and length of watch time. The Web-based survey assessed implementation outcomes of the video, such as acceptability, appropriateness, penetration, and adoption.

RESULTS

As of November 4, 2018 (5 years after launch), the video had 237,132 unique views from 182 countries, with most viewers watching an average of 55.1% (76/138 seconds) of the video. Overall, both parents and HCPs reported strong acceptance of the video (ie, they liked the video, found it helpful, and felt more confident) and reported significant improvements in plans to use distraction, deep breathing, and topical anesthetic creams.

CONCLUSIONS

This parent-directed YouTube video was an acceptable and appropriate way to disseminate evidence about the procedure of pain management to a large number of parents.

Efficacy of Sucrose in Reducing Pain during Immunization among 10- to 18-Month-Old Infants and Young Children: A Randomized Controlled Trial

PURPOSE

Sucrose is recommended to reduce pain associated with vaccination in neonates. However, research results concerning its effectiveness in infants and young children are inconclusive. This study aims to determine the efficacy of sucrose administration in reducing pain during immunization in 10- to 18-month-old infants and young children as assessed by behavioral pain parameters, crying time, and saliva substance (P) concentration.

DESIGN AND METHODS

This was a double-blind, randomized controlled trial and included healthy infants and young children undergoing their 10- to 18-month immunization. Behavioral pain outcome was measured during, and shortly after the last injection. The infant's pain was also measured by a salivary test using substance (P), and videotaping of crying time.

RESULTS

The study results indicate that, compared with a placebo group, the sucrose group had significantly less pain post-immunization (F (1,129) = 1.72, p = 0.001). Moreover, substance (P) was lower in the intervention group post-immunization, and it could be considered a good predictor of pain reduction associated with immunization.

CONCLUSIONS

Sucrose administration during immunization injection helps in reducing pain, which is one of the most critical factors affecting compliance with the immunization schedule. Substance (P) measurement can be used as a predictor of immunization pain level in 10- to 18-month-old infants and young children.

PRACTICE IMPLICATIONS

Sucrose is an effective method to reduce needle pain during immunization; therefore, healthcare providers should administer sucrose as a pain relief intervention in the immunization clinical setting.

Nonpharmacologic Management of Pain During Common Needle Puncture Procedures in Infants: Current Research Evidence and Practical Considerations: An Update

Infants undergo painful procedures involving skin puncture as part of routine medical care. Pain from needle puncture procedures is suboptimally managed. Numerous nonpharmacologic interventions are available that may be used for these painful procedures, including swaddling/containment, pacifier/non-nutritive sucking, rocking/holding, breastfeeding and breastmilk, skin-to-skin care, sweet tasting solutions, music therapy, sensorial saturation, and parental presence. Adoption these interventions into routine clinical practice is feasible and should be a standard of care in quality health care for infants. This review summarizes the epidemiology of pain from common needle puncture procedures in infants, the effectiveness of nonpharmacologic interventions, implementation considerations, and unanswered questions.

External cold and vibration for pain management of children undergoing needle-related procedures in the emergency department: a randomised controlled non-inferiority trial protocol

INTRODUCTION

Needle-related procedures are considered as the most important source of pain and distress in children in hospital settings. Considering the physiological and psychological consequences that could result from these procedures, management of pain and distress through pharmacological and non-pharmacological methods is essential. Therefore, it is important to have interventions that are rapid, easy-to-use and likely to be translated into clinical practice for routine use. The aim of this study will be to determine whether a device combining cold and vibration (Buzzy) is non-inferior to a topical anaesthetic (liposomal lidocaine 4% cream) for pain management of children undergoing needle-related procedures in the emergency department.

METHODS AND ANALYSIS

This study will be a randomised controlled non-inferiority trial comparing the Buzzy device to liposomal lidocaine 4% cream for needle-related pain management. A total of 346 participants will be randomly assigned in a 1:1 ratio to one of the two study groups. The primary outcome will be the mean difference in pain intensity between groups during needle-related procedures. A non-inferiority margin of 0.70 on the Color Analogue Scale will be considered. A Non-inferiority margin of 0.70 on the Color Analogue Scale will be considered. The secondary outcomes will be the level of distress during the procedure, the success of the procedure at first attempt, the occurrence of adverse events, the satisfaction of both interventions and the memory of pain 24 hours after the procedure. The primary outcome will be assessed for non-inferiority and the secondary outcomes for superiority.

ETHICS AND DISSEMINATION

This study protocol was reviewed and approved by the institutional review board of the study setting. Findings of this trial will be disseminated via peer-reviewed publications and conference presentations.

Is kangaroo mother care effective in alleviating vaccination associated pain in early infantile period? A RCT

BACKGROUND

Childhood vaccination is a common procedure and a part of routine medical care during infancy. Although vaccination is the cornerstone for prevention of many infectious diseases, it is associated with significant pain, which is often ignored. Non pharmacological interventions such as breast feeding and kangaroo mother care (KMC) have been used to decrease this procedural pain. However there is paucity of published data on effective use of KMC in term neonates and infants beyond the neonatal age.

METHOD

This randomized controlled trial included 61 infants ≤14 weeks of postnatal age, and compared KMC to swaddling during vaccination. Neonatal infant pain scale (NIPS) was used to assess the pain associated with vaccination.

RESULTS

NIPS scores at 1 min and 5 min after vaccination and duration of cry were significantly less in the KMC group.

CONCLUSION

KMC is effective in reducing vaccination associated pain in young infants.

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.

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.

Parental Approach to the Prevention and Management of Fever and Pain Following Childhood Immunizations: A Survey Study

Antipyretic analgesics are commonly used to prevent and treat adverse events following immunizations. Current practice discourages routine use due to possible blunting of vaccine immune responses. We surveyed 150 parents/caregivers of recently vaccinated 6- and 15-month-old children to determine the prevalence of and beliefs regarding antipyretic analgesics use around vaccinations. 11% used them prophylactically, before vaccination. Use in the first 48 hours after vaccination was 64%, primarily to prevent and/or treat fever and pain. Acetaminophen was administered 2.6 times more frequently than ibuprofen. Ibuprofen was used more in the 15-month compared with the 6-month-old children (28% vs 7.4%, respectively, P = .001). The majority of caregivers disagreed with their use for fever (53%) or pain (59%). Antipyretic analgesic use, including prophylaxis, around vaccinations was common in our study population. Effective interventions are needed to target parents/caregivers to eliminate unnecessary antipyretic analgesic use around vaccination time and foster nonmedication alternatives.

Relative effectiveness of additive pain interventions during vaccination in infants

BACKGROUND

Vaccine injections can cause acute pain and distress in infants, which can contribute to dissatisfaction with the vaccination experience and vaccine hesitancy. We sought to compare the effectiveness of additive pain interventions administered consistently during vaccine injections in the first year of life.

METHODS

We conducted a multicentre, longitudinal, double-blind, add-on, randomized controlled trial. Healthy infants were randomly assigned to 1 of 4 levels of pain management for all vaccine injections at 2, 4, 6 and 12 months: (i) placebo control; (ii) parent-directed video education about infant soothing; (iii) the video plus sucrose administered orally or (iv) the video plus sucrose plus liposomal lidocaine applied topically. All infants benefit from injection techniques that minimize pain. We used a double-dummy design; hence all parents watched a video (active psychological intervention or placebo) and all infants received oral solution (sucrose or placebo) and topical cream (lidocaine or placebo). We assessed infant distress during 3 phases - preinjection (baseline), vaccine injection (needle), and 1 minute postinjection (recovery) - using the Modified Behavioural Pain Scale (range 0-10). We compared scores between groups and across infant ages using a mixed-model repeated-measures analysis.

RESULTS

A total of 352 infants participated in the study, from Jan. 17, 2012, to Feb. 2, 2016. Demographics did not differ among intervention groups (p > 0.05). Baseline pain scores did not differ among intervention groups (p = 0.4), but did differ across ages (p < 0.001). Needle pain scores differed among groups (p = 0.003) and across ages (p < 0.001). The mean (± standard deviation) needle score was 6.3 (± 0.8) in the video-sucrose-lidocaine group compared with 6.7 (± 0.8) in each of the other groups. There were no other between-group differences. Recovery scores did not differ among groups (p = 0.98), but did differ across ages (p < 0.001).

INTERPRETATION

Only liposomal lidocaine provided consistent analgesia within an additive pain intervention regimen during vaccinations in infants. Trial registration: ClinicalTrials.gov, no. NCT01503060.

Experiencing Support During Needle-Related Medical Procedures: A Hermeneutic Study With Young Children (3-7Years)

Needle-related medical procedures (NRMPs) are something that all young children need to undergo at some point. These procedures may involve feelings of fear, pain and anxiety, which can cause problems later in life either when seeking healthcare in general or when seeking care specifically involving needles. More knowledge is needed about supporting children during these procedures.

AIM

This study aims to explain and understand the meaning of the research phenomenon: support during NRMPs. The lived experiences of the phenomenon are interpreted from the perspective of younger children.

METHOD

The analysis uses a lifeworld hermeneutic approach based on participant observations and interviews with children between 3 and 7years of age who have experienced NRMPs.

RESULTS

The research phenomenon, support for younger children during NRMPs, is understood through the following themes: being the centre of attention, getting help with distractions, being pampered, becoming involved, entrusting oneself to the safety of adults and being rewarded. A comprehensive understanding is presented wherein younger children experience support from adults during NRMPs in order to establish resources and/or strengthen existing resources.

CONCLUSIONS

The manner in which the child will be guided through the procedure is developed based on the child's reactions. This approach demonstrates that children are actively participating during NRMPs. Supporting younger children during NRMPs consists of guiding them through a shared situation that is mutually beneficial to the child, the parent and the nurse. Play during NRMP is an important tool that enables the support to be perceived as positive.

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.

Pharmacologic Treatment of Pain

Adolescents and children are frequently affected by chronic pain conditions that can lead to disability and distress. The best approach to evaluation and treatment of these conditions involves use of the biopsychosocial model, which includes use of medication management. Chronic pain conditions are treated pharmacologically with a number of different medication classes via several routes of administration as drug delivery systems have progressed. These include anti-inflammatory drugs, muscle relaxants, antiepileptic medicines, antidepressants, opioids, and local anesthetics. Most are prescribed without regulatory body approval to treat specific pain syndromes as data to support their use are sparse. Medical decision making is guided by experience, empiric evidence, extrapolation from adult studies, and matching medication classes with the theorized mechanism of the pain condition. It is not recommended that nonpain practitioners prescribe opioid medications for treatment of chronic pain conditions, and pain management practitioners should seek to minimize their use. The appropriate and commonly used medications for pain conditions are presented in this narrative review.

Live Music Therapy as an Active Focus of Attention for Pain and Behavioral Symptoms of Distress During Pediatric Immunization

A total of 100 children coming for routine immunization to pediatric outpatient department were included and were divided into experiment (n = 50) and control (n = 50) groups. Experiment group received live music therapy during immunization procedure. Control group received no intervention. The Modified Behavior Pain Scale (MBPS), 10-point pain levels, and 10-point distress levels were documented by parents. Duration of crying was recorded by investigators. Pre- and postimmunization blood pressures and heart rates of parents holding the children were also measured and recorded by investigators. Independent and paired t tests were used for analysis. All 3 domains of the Modified Behavior Pain Scale and duration of crying showed significant improvement (P < .05) in the experiment group. Pain and distress levels also showed statistically nonsignificant improvement in experiment group. Blood pressure and heart rate of parents showed no difference. Music therapy could be helpful to children, parents, and health care providers by reducing discomfort of the child during pediatric immunization.

Vapocoolants (cold spray) for pain treatment during intravenous cannulation

BACKGROUND

Intravenous cannulation is a painful procedure that can provoke anxiety and stress. Injecting local anaesthetic can provide analgesia at the time of cannulation, but it is a painful procedure. Topical anaesthetic creams take between 30 and 90 minutes to produce an effect. A quicker acting analgesic allows more timely investigation and treatment. Vapocoolants have been used in this setting, but studies have reported mixed results.

OBJECTIVES

To determine effects of vapocoolants on pain associated with intravenous cannulation in adults and children. To explore variables that might affect the performance of vapocoolants, including time required for application, distance from the skin when applied and time to cannulation. To look at adverse effects associated with the use of vapocoolants.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Latin American Caribbean Health Sciences Literature (LILACS), the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Institute for Scientific Information (ISI) Web of Science and the http://clinicaltrials.gov/, http://www.controlled-trials.com/ and http://www.trialscentral.org/ databases to 1 May 2015. We applied no language restrictions. We also scanned the reference lists of included papers.

SELECTION CRITERIA

We included all blinded and unblinded randomized controlled trials (RTCs) comparing any vapocoolant with placebo or control to reduce pain during intravenous cannulation in adults and children.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed trial quality and extracted data, contacted study authors for additional information and assessed included studies for risk of bias. We collected and analysed data for the primary outcome of pain during cannulation, and for the secondary outcomes of pain associated with application of the vapocoolant, first attempt success rate of intravenous cannulation, adverse events and participant satisfaction. We performed subgroup analyses for the primary outcome to examine differences based on age of participant, type of vapocoolant used, application time of vapocoolant and clinical situation (emergency vs elective). We used random-effects model meta-analysis in RevMan 5.3 and assessed heterogeneity between trial results by examining forest plots and calculating the I(2) statistic.

MAIN RESULTS

We found nine suitable studies of 1070 participants and included them in the qualitative analyses. We included eight studies of 848 participants in the meta-analysis for the primary outcome (pain during intravenous cannulation). Use of vapocoolants resulted in a reduction in pain scores as measured by a linear 100 mm visual analogue scale (VAS 100) compared with controls (difference between means -12.5 mm, 95% confidence interval (CI) -18.7 to -6.4 mm; moderate-quality evidence). We could not include in the meta-analysis one study, which showed no effects of the intervention.Use of vapocoolants resulted in increased pain scores at the time of application as measured by a VAS 100 compared with controls (difference between means 6.3 mm, 95% CI 2.2 to 10.3 mm; four studies, 461 participants; high-quality evidence) and led to no difference in first attempt success compared with controls (risk ratio (RR) 1.00, 95% CI 0.94 to 1.06; six studies, 812 participants; moderate-quality evidence). We documented eight minor adverse events reported in 279 vapocoolant participants (risk difference (RD) 0.03, 95% CI 0 to 0.05; five studies, 551 participants; low quality-evidence).The overall risk of bias of individual studies ranged from low to high, with high risk of bias for performance and detection bias in four studies. Sensitivity analysis showed that exclusion of studies at high or unclear risk of bias did not materially alter the results of this review.

AUTHORS' CONCLUSIONS

Moderate-quality evidence indicates that use of a vapocoolant immediately before intravenous cannulation reduces pain during the procedure. Use of vapocoolant does not increase the difficulty of cannulation nor cause serious adverse effects but is associated with mild discomfort during application.

The effect of sucrose as pain relief/comfort during immunisation of 15-month-old children in health care centres: a randomised controlled trial

AIMS AND OBJECTIVES

To investigate the effect of 30% sucrose compared with a placebo (water) as pain relief and comfort during immunisation of 15-month-old children in health care centres.

BACKGROUND

Children experience different levels of pain and distress during immunisation. Sweet solutions function as pain relief during immunisation for infants up to one year of age. However, there are few studies of older children.

DESIGN

An experimental design in which the participants (15-month-old infants) were randomly assigned to an intervention group that received a 30% sugar solution or a control group that received a placebo (water).

METHODS

The study was performed at three health care centres in a large Norwegian municipality. The parents of all 15-month-old infants who were recommended for vaccination (for measles, mumps and rubella) between 5 September 2013 and 31 March 2014 were invited to have their infant participate. Duration of crying was the outcome measure.

RESULTS

A total of 114 children were included (59 in the intervention group, 55 in the control group). The intervention group infants' crying was shorter (18 seconds mean) compared with the control group infants (33 seconds mean). The difference in crying duration between the groups was both statistically and clinically significant.

CONCLUSION

This trial revealed that 30% sucrose orally has a calming and pain-relieving effect on 15-month-old infants during immunisation.

RELEVANCE TO CLINICAL PRACTICE

Public health nurses should use a 30% sucrose solution for pain relief during immunisation of 15-month-old infants.

Why are children still crying? Going beyond "evidence" in guideline development to improve pain care for children: the HELPinKIDS experience

The failure to translate research evidence into day-to-day clinical practices is identified as a significant reason for suboptimal quality care across the health system, including procedural pain management in children. Clinical practice guidelines (CPGs) have been developed to assist in this process by synthesizing and interpreting research evidence for end users. Numerous CPGs have been developed for procedural pain management in children, yet gaps persist in the adoption of best practices. This article reviews the experience and approach of 1 guideline development group, the Help ELiminate Pain in KIDS Team (HELPinKIDS), in incorporating implementation considerations and knowledge translation (KT) strategies within the process of guideline development for the HELPinKIDS CPG about childhood vaccination pain management to facilitate greater uptake of the CPG. Specific areas that will be addressed include partnerships with stakeholders, rigor of guideline development, issues of implementation, and editorial independence. The work of HELPinKIDS was guided by a KT map, which identified, at a high level, the target audiences, key messages, tools, and strategies that could be used to communicate, disseminate, and implement the CPG into diverse settings. Examples of impact at both the individual and systems levels from HELPinKIDS KT activities are also presented.

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.

Procedural and Physical Interventions for Vaccine Injections: Systematic Review of Randomized Controlled Trials and Quasi-Randomized Controlled Trials

BACKGROUND

This systematic review evaluated the effectiveness of physical and procedural interventions for reducing pain and related outcomes during vaccination.

DESIGN/METHODS

Databases were searched using a broad search strategy to identify relevant randomized and quasi-randomized controlled trials. Data were extracted according to procedure phase (preprocedure, acute, recovery, and combinations of these) and pooled using established methods.

RESULTS

A total of 31 studies were included. Acute infant distress was diminished during intramuscular injection without aspiration (n=313): standardized mean difference (SMD) -0.82 (95% confidence interval [CI]: -1.18, -0.46). Injecting the most painful vaccine last during vaccinations reduced acute infant distress (n=196): SMD -0.69 (95% CI: -0.98, -0.4). Simultaneous injections reduced acute infant distress compared with sequential injections (n=172): SMD -0.56 (95% CI: -0.87, -0.25). There was no benefit of simultaneous injections in children. Less infant distress during the acute and recovery phases combined occurred with vastus lateralis (vs. deltoid) injections (n=185): SMD -0.70 (95% CI: -1.00, -0.41). Skin-to-skin contact in neonates (n=736) reduced acute distress: SMD -0.65 (95% CI: -1.05, -0.25). Holding infants reduced acute distress after removal of the data from 1 methodologically diverse study (n=107): SMD -1.25 (95% CI: -2.05, -0.46). Holding after vaccination (n=417) reduced infant distress during the acute and recovery phases combined: SMD -0.65 (95% CI: -1.08, -0.22). Self-reported fear was reduced for children positioned upright (n=107): SMD -0.39 (95% CI: -0.77, -0.01). Non-nutritive sucking (n=186) reduced acute distress in infants: SMD -1.88 (95% CI: -2.57, -1.18). Manual tactile stimulation did not reduce pain across the lifespan. An external vibrating device and cold reduced pain in children (n=145): SMD -1.23 (95% CI: -1.58, -0.87). There was no benefit of warming the vaccine in adults. Muscle tension was beneficial in selected indices of fainting in adolescents and adults.

CONCLUSIONS

Interventions with evidence of benefit in select populations include: no aspiration, injecting most painful vaccine last, simultaneous injections, vastus lateralis injection, positioning interventions, non-nutritive sucking, external vibrating device with cold, and muscle tension.

Impact of parent-directed education on parental use of pain treatments during routine infant vaccinations: a cluster randomized trial

Educating parents about ways to minimize pain during routine infant vaccine injections at the point of care may positively impact on pain management practices. The objective of this cluster randomized trial was to determine the impact of educating parents about pain in outpatient pediatric clinics on their use of pain treatments during routine infant vaccinations. Four hospital-based pediatric clinics were randomized to intervention or control groups. Parents of 2- to 4-month-old infants attending the intervention clinics reviewed a pamphlet and a video about vaccination pain management on the day of vaccination, whereas those in the control clinics did not. Parent use of specific pain treatments (breastfeeding, sugar water, topical anesthetics, and/or holding of infants) on the education day and at subsequent routine vaccinations 2 months later was the primary outcome. Altogether, 160 parent-infant dyads (80 per group) participated between November 2012 and February 2014; follow-up data were available for 126 (79%). Demographics did not differ between groups (P > 0.05). On the education day and at follow-up vaccinations, use of pain interventions during vaccinations was higher in the intervention group (80% vs 26% and 68% vs 32%, respectively; P < 0.001 for both analyses). Educating parents about pain management in a hospital outpatient setting leads to higher use of pain interventions during routine infant vaccinations.

A randomized trial of rotavirus vaccine versus sucrose solution for vaccine injection pain

OBJECTIVE

Sucrose solutions are analgesic in infants. Oral rotavirus vaccine contains sucrose, however, it is not known if it possesses analgesic properties. The objective was to compare the analgesic effectiveness of rotavirus vaccine to sucrose solution when administered prior to injectable vaccines.

METHODS

Infants 2-4 months of age receiving oral rotavirus vaccine and two separate injectable vaccines on the same day were randomized to rotavirus vaccine (Rotarix) first followed by the injectable vaccines and sucrose (Tootsweet) afterwards, or vice versa. Pain was assessed by blinded raters using the Numerical Rating Scale (NRS, range 0-10) (parents, clinicians), or Modified Behavioural Pain Scale (MBPS, range 0-10) and cry duration (observers). Data were analyzed using t-tests or χ(2)-tests; Bonferroni correction was applied to correct for multiple comparisons, as appropriate.

RESULTS

Altogether, 120 infants participated: 60 were randomized to rotavirus vaccine first. Groups did not differ in demographics, including; age (p=0.448) and sex (p=0.464). The mean pain score (standard deviation) for both vaccine injections did not differ between infants given rotavirus vaccine first versus sucrose solution first: observer MBPS, parent NRS and clinician NRS scores were 7.4 (1.6) vs. 7.7 (1.6), 4.9 (2.1) vs. 5.8 (2.1), and 4.2 (2.1) vs. 4.6 (2.2), respectively. Similarly, there was no difference between groups in cry duration.

CONCLUSION

Rotavirus vaccine did not differ from sucrose solution in reducing injection-induced pain. Based on the findings, it is recommended that rotavirus vaccine be administered prior to injectable vaccines in infants aged 2 and 4 months.
