Randomised trial of analgesic effects of sucrose, glucose, and pacifiers in term neonates

"Feed-and-wrap" technique versus deep sedation for neonatal magnetic resonance imaging: a retrospective comparative study

OBJECTIVES

Neonatal MRI is usually performed under deep sedation, which is challenging-especially in low-weight premature patients. In addition, long-term side effects, such as neurotoxicity, are of concern. An alternative to sedation is to induce natural sleep by feeding and immobilising the child, the "feed-and-wrap" technique (FWT). The objective of this study was to evaluate differences in image quality between neonates examined under sedation and by using the FWT during the first four months of life.

MATERIALS AND METHODS

We retrospectively assessed image quality (based on a 4-point semiquantitative scale) of all MRI examinations in neonates performed at our institution between July 2009 and August 2022. Differences in image quality between examinations under sedation versus FWT were evaluated.

RESULTS

We included 432 consecutive patients, 243 (56%) using sedation and 189 (44%) using the FWT. Corrected age and body weight (mean ± SD: 3.7 ± 1.1 versus 4.5 ± 1.3 kg, p < 0.001) were significantly lower in the FWT group. The overall success rate in the FWT group was 95%. Image quality was slightly lower when using the FWT (mean ± SD: 3.7 ± 0.43 versus 3.96 ± 0.11, p < 0.001). Multivariate analysis showed a higher risk of acquiring sequences with diagnostic limitations in the FWT group (p < 0.001), increasing with corrected age (p = 0.048).

CONCLUSION

The FWT is a highly successful method to perform MRI scans in term and preterm neonates. Overall image quality is only slightly lower than under sedation. Especially in immature low-weight preterm patients, the FWT is a reliable option to perform MRI studies without exposing the child to risks associated with sedation.

CLINICAL RELEVANCE STATEMENT

The "feed-and-wrap" technique enables high-quality MRI examinations in neonates, including low-weight premature patients. Deep sedation for diagnostic MRI procedures in this age group, which has the risk of short- and long-term complications, can often be avoided.

KEY POINTS

Deeply sedating neonates for MR examinations comes with risks. Image quality is only slightly lower when using the "feed-and-wrap" technique. The "feed-and-wrap" technique is feasible even in low-weight premature infants.

An Analgesic Technique for Orogastric Tube Insertion in Newborns: DOLATSONG, a Randomized Multicentric Controlled Trial

BACKGROUND

Gastric tube insertion is necessary to support early enteral feeding of newborns during their neonatal intensive care stay. This frequent and invasive procedure is known to be painful. Very few analgesic techniques (sweet solutions, sucking, swaddling, and skin-to-skin contact) are available to reduce the pain caused by orogastric tube insertion procedure.

OBJECTIVE

To determine whether a new orogastric tube insertion technique modifies the pain response in newborns, we hypothesize that inserting an orogastric tube through the nipple of a bottle reduces pain caused by this procedure.

DESIGN

Prospective, controlled, randomized, multicentered and open label study.

SETTINGS

Three neonatal intensive care units in France (2 level 3 units and 1 level 2B).

PARTICIPANTS

Full-term or premature newborns at 32 weeks of gestation or more, postnatal age between 48 hours and 21 days, not ventilated and requiring enteral feeding, were randomized into 2 groups: usual technique (n = 36) and experimental technique (n = 35).

METHODS

Our experimental technique was to insert the orogastric tube through a modified nipple of a bottle. This method was compared with the usual technique of inserting the tube directly into the newborn's mouth without a support to guide it accompanied by a nipple encouraging sucking with a nonnutritive solution. An association of nonnutritive sucking and orally administered 30% glucose was given to all children for analgesic purposes. Pain during the orogastric tube insertion was assessed on video recordings by 2 independent experts, using a heteroassessment behavioral scale for pain (DAN-Douleur Aiguë du Nouveau-né; APN-Acute Pain in Newborns). The primary outcome was an Acute Pain in Newborns score of less than 3 at the time of the procedure. Comparisons were made using Fisher exact test or Mann-Whitney U test. Factors associated with an Acute Pain in Newborns score of 3 and greater were explored using univariable and multivariable regression models.

RESULTS

All but 1 video recording in each group were analyzed. Among the 34 neonates in the experimental group, 71.4% (95% CI: [53.7-85.4]) had an Acute Pain in Newborns score of less than 3 during orogastric tube insertion versus 41% (95% CI: [27.9-61.9]) in the control group (P = .031). Gagging was frequent and nonsignificantly different between the 2 groups (69% in the control group, 51% in the experimental group, P = .13). In multivariable analysis, the experimental technique was an independent factor of pain prevention compared with the usual technique (odds ratio = 0.21 [0.06-0.71], P = .015).

CONCLUSIONS

This study suggests that a simple, inexpensive, and feasible technique of orogastric tube insertion through the nipple of a bottle limits pain associated with this procedure in newborns.

Effects of Dextrose Supplementation on Chloral Hydrate Sedation: A Double-Blinded, Randomized, Prospective Study

Sedation plays a crucial role in successful pediatric imaging, and chloral hydrate is commonly used for this purpose. However, the challenges associated with chloral hydrate administration, such as its unpleasant taste and potential induction of vomiting, remain a concern. Sweet oral solutions have emerged as potential solutions for reducing distress and providing analgesia. This study compared the efficacy of dextrose combined with chloral hydrate with that of conventional sedation methods. This prospective, double-blind, randomized controlled clinical study enrolled 160 pediatric outpatients scheduled for echocardiography. Chloral hydrate syrup (100 mg/mL) was supplemented with a dextrose solution (dextrose group) or distilled water (control group) in a 1:10 volume ratio. The sedation achievement time, Skeie scale score, revised Face, Legs, Activity, Cry, and Consolability (FLACC) score, and side effects (nausea, vomiting, hypoxia, and respiratory depression) were assessed. No significant difference in average time to achieve sedation was observed between the dextrose and control groups (24.4±17.8 vs. 24.7±17.1 min, p=0.92). Both groups demonstrated similar levels of sedation according to the Skeie scale and mean revised FLACC score. Although the occurrence rates of nausea and vomiting had no significant differences, the dextrose group had no cases of vomiting in children aged >24 months compared to the control group, which had three cases (30%). In conclusion, the addition of dextrose to chloral hydrate did not significantly affect sedation time, anxiety, pain reduction, or occurrence of gastrointestinal complications during sedation.

Evaluation of the effectiveness of sucrose versus xylitol application in minimizing pain related to dental injection in 5-7-year-old children - A randomized controlled pilot study

Background

Oral application of sweet-tasting solutions has found to be effective in minimizing pain on dental injection in children. Xylitol has never been tested in this regard.

Aim

The aim of this study was to compare the effectiveness of prior application of sucrose versus xylitol solution in minimizing pain on dental injection in 5-7-year-old children.

Settings and Design

This study was a randomized controlled clinical trial.

Materials and Methods

Informed consent was taken. A total of 30 children who required maxillary buccal infiltration injection were selected. The children were randomly allocated into the sucrose group, xylitol group, or control group by lottery method. In the sucrose and xylitol groups, 30% sucrose or 30% xylitol solution was applied on the lateral surface of the tongue for 2 min. In the control group, distilled water was applied. In all the groups, the topical anesthetic was applied at the site of injection followed by buccal infiltration. A video was taken during injection, and the sound eye-motor (SEM) scale was recorded by a blinded examiner. Patients were asked to self-evaluate using the Wong-Baker Faces Pain Scale (WBFPS).

Statistical Analysis

Mann-Whitney test was used to analyze the data.

Results

There was a statistically significant difference in the WBFPS and the SEM score between the sucrose and the control group (P < 0.05) and the xylitol and control group (P < 0.05). No statistically significant difference was found between the sucrose and xylitol group.

Conclusion

The application of xylitol solution before dental injection was as effective as sucrose solution in minimizing pain during the injection.

Non-pharmacological management of infant and young child procedural pain

BACKGROUND

Despite evidence of the long-term implications of unrelieved pain during infancy, it is evident that infant pain is still under-managed and unmanaged. Inadequately managed pain in infancy, a period of exponential development, can have implications across the lifespan. Therefore, a comprehensive and systematic review of pain management strategies is integral to appropriate infant pain management. This is an update of a previously published review update in the Cochrane Database of Systematic Reviews (2015, Issue 12) of the same title.

OBJECTIVES

To assess the efficacy and adverse events of non-pharmacological interventions for infant and child (aged up to three years) acute pain, excluding kangaroo care, sucrose, breastfeeding/breast milk, and music.

SEARCH METHODS

For this update, we searched CENTRAL, MEDLINE-Ovid platform, EMBASE-OVID platform, PsycINFO-OVID platform, CINAHL-EBSCO platform and trial registration websites (ClinicalTrials.gov; International Clinical Trials Registry Platform) (March 2015 to October 2020). An update search was completed in July 2022, but studies identified at this point were added to 'Awaiting classification' for a future update.  We also searched reference lists and contacted researchers via electronic list-serves.  We incorporated 76 new studies into the review.  SELECTION CRITERIA: Participants included infants from birth to three years in randomised controlled trials (RCTs) or cross-over RCTs that had a no-treatment control comparison. Studies were eligible for inclusion in the analysis if they compared a non-pharmacological pain management strategy to a no-treatment control group (15 different strategies). In addition, we also analysed studies when the unique effect of adding a non-pharmacological pain management strategy onto another pain management strategy could be assessed (i.e. additive effects on a sweet solution, non-nutritive sucking, or swaddling) (three strategies). The eligible control groups for these additive studies were sweet solution only, non-nutritive sucking only, or swaddling only, respectively. Finally, we qualitatively described six interventions that met the eligibility criteria for inclusion in the review, but not in the analysis.  DATA COLLECTION AND ANALYSIS: The outcomes assessed in the review were pain response (reactivity and regulation) and adverse events. The level of certainty in the evidence and risk of bias were based on the Cochrane risk of bias tool and the GRADE approach. We analysed the standardised mean difference (SMD) using the generic inverse variance method to determine effect sizes.  MAIN RESULTS: We included total of 138 studies (11,058 participants), which includes an additional 76 new studies for this update. Of these 138 studies, we analysed 115 (9048 participants) and described 23 (2010 participants) qualitatively. We described qualitatively studies that could not be meta-analysed due to being the only studies in their category or statistical reporting issues. We report the results of the 138 included studies here. An SMD effect size of 0.2 represents a small effect, 0.5 a moderate effect, and 0.8 a large effect. The thresholds for the I2 interpretation were established as follows: not important (0% to 40%); moderate heterogeneity (30% to 60%); substantial heterogeneity (50% to 90%); considerable heterogeneity (75% to 100%). The most commonly studied acute procedures were heel sticks (63 studies) and needlestick procedures for the purposes of vaccines/vitamins (35 studies). We judged most studies to have high risk of bias (103 out of 138), with the most common methodological concerns relating to blinding of personnel and outcome assessors. Pain responses were examined during two separate pain phases: pain reactivity (within the first 30 seconds after the acutely painful stimulus) and immediate pain regulation (after the first 30 seconds following the acutely painful stimulus). We report below the strategies with the strongest evidence base for each age group. In preterm born neonates, non-nutritive sucking may reduce pain reactivity (SMD -0.57, 95% confidence interval (CI) -1.03 to -0.11, moderate effect; I2 = 93%, considerable heterogeneity) and improve immediate pain regulation (SMD -0.61, 95% CI -0.95 to -0.27, moderate effect; I2 = 81%, considerable heterogeneity), based on very low-certainty evidence. Facilitated tucking may also reduce pain reactivity (SMD -1.01, 95% CI -1.44 to -0.58, large effect; I2 = 93%, considerable heterogeneity) and improve immediate pain regulation (SMD -0.59, 95% CI -0.92 to -0.26, moderate effect; I2 = 87%, considerable heterogeneity); however, this is also based on very low-certainty evidence. While swaddling likely does not reduce pain reactivity in preterm neonates (SMD -0.60, 95% CI -1.23 to 0.04, no effect; I2 = 91%, considerable heterogeneity), it has been shown to possibly improve immediate pain regulation (SMD -1.21, 95% CI -2.05 to -0.38, large effect; I2 = 89%, considerable heterogeneity), based on very low-certainty evidence. In full-term born neonates, non-nutritive sucking may reduce pain reactivity (SMD -1.13, 95% CI -1.57 to -0.68, large effect; I2 = 82%, considerable heterogeneity) and improve immediate pain regulation (SMD -1.49, 95% CI -2.20 to -0.78, large effect; I2 = 92%, considerable heterogeneity), based on very low-certainty evidence.  In full-term born older infants, structured parent involvement was the intervention most studied. Results showed that this intervention has little to no effect in reducing pain reactivity (SMD -0.18, 95% CI -0.40 to 0.03, no effect; I2 = 46%, moderate heterogeneity) or improving immediate pain regulation (SMD -0.09, 95% CI -0.40 to 0.21, no effect; I2 = 74%, substantial heterogeneity), based on low- to moderate-certainty evidence. Of these five interventions most studied, only two studies observed adverse events, specifically vomiting (one preterm neonate) and desaturation (one full-term neonate hospitalised in the NICU) following the non-nutritive sucking intervention. The presence of considerable heterogeneity limited our confidence in the findings for certain analyses, as did the preponderance of evidence of very low to low certainty based on GRADE judgements.

AUTHORS' CONCLUSIONS

Overall, non-nutritive sucking, facilitated tucking, and swaddling may reduce pain behaviours in preterm born neonates. Non-nutritive sucking may also reduce pain behaviours in full-term neonates. No interventions based on a substantial body of evidence showed promise in reducing pain behaviours in older infants. Most analyses were based on very low- or low-certainty grades of evidence and none were based on high-certainty evidence. Therefore, the lack of confidence in the evidence would require further research before we could draw a definitive conclusion.

Nutritional geometry framework of sucrose taste in Drosophila

Dietary protein (P) and carbohydrate (C) have a major impact on sweet taste sensation. However, it remains unclear whether the balance of P and C influences sweet taste sensitivity. Here, we use the nutritional geometry framework (NGF) to address the interaction of protein and carbohydrates and on sweet taste using Drosophila as a model. Our results reveal that high-protein, low-carbohydrate (HPLC) diets sensitize to sweet taste and low-protein, high-carbohydrate (LPHC) diets desensitize sweet taste in both male and female flies. We further investigate the underlying mechanisms of these two diets' effect on sweet taste using RNA sequencing. When compared to the LPHC diet, the mRNA expression of genes involved in the metabolism of glycine, serine, and threonine is significantly upregulated in the HPLC diet, suggesting these amino acids may mediate sweet taste perception. We further find that sweet sensitization occurs in flies fed with the LPHC diet supplemented with serine and threonine. Our study demonstrates that sucrose taste sensitivity is affected by the balance of dietary protein and carbohydrates possibly through changes in serine and threonine.

Efficacy of 2 Nonpharmaceutical (Non-nutritive Sucking and Human Care Contact) Pain Relief Measures for Idiopathic Clubfoot Casted Using Ponseti Technique

PURPOSE

This study aimed at exploring the pain and physiological responses exhibited during Ponseti manipulation and casting in clubfoot infants. In addition, we compared the efficacy of 2 nonpharmaceutical techniques (non-nutritive sucking and human care contact) for tackling these responses.

METHODS

The study included children with unilateral and bilateral idiopathic clubfeet between 15 days to 6 months of age. For comparisons, children were divided into control group without any intervention (group A), non-nutritive sucking group (group B), and human care contact group (group C). Pain score (Neonatal Infant Pain Score), heart rate (HR), and oxygen saturation (SpO2) was assessed before, during and 1 minute after casting. These measurements were compared using statistical methods.

RESULTS

There were 16 children (11 bilateral) in group A, 17 (10 bilateral) in group B, and 18 (8 bilateral) in group C. Before casting, the baseline parameters (Neonatal Infant Pain Score, HR, and SpO2) of the 3 groups were comparable. Groups B and C had a significant reduction in pain score at casting and in postcasting period when compared with group A (P<0.05). Group B (at casting-mean: 174.1/min, postcasting-mean: 168.2/min) had the lowest HR both during and after cast application. Group B had the highest SpO2 among all the 3 groups, both during casting (mean: 95.7%) and after casting (mean: 97.4%) (P<0.05).

CONCLUSIONS

Infants exhibit moderate pain response and altered physiological responses during and after Ponseti casting. Non-nutritive sucking emerged as a better method to lessen these parameters when compared with the conventional technique and human care contact.

Strategies to perform magnetic resonance imaging in infants and young children without sedation

Given the increasing use of MRI in the pediatric population, the need for sedation in MRI performed in young children is a topic of growing importance. Although sedation is generally tolerated well by children, the financial and operational impacts of anesthesia on MRI workflow, as well as potential adverse effects of anesthetic medications, highlight the need to perform MRI in children without sedation whenever possible. This review focuses on current techniques to facilitate non-sedation MRI in children, including exam preparation with MRI simulation; asleep but not sedated techniques; awake and relaxed techniques using certified child life specialists, animal-assisted therapy, a child-friendly environment and in-scan entertainment; and non-sedated MRI protocol modifications such as shorter scan time, prioritizing sequences, reducing motion artifact, noise reduction, limiting use of gadolinium, employing an open MRI and modifying protocols.

Factors associated with non-nutritive sucking habits at 2 years of age among very preterm children: EPIPAGE-2 cohort study

BACKGROUND

The association between prolonged non-nutritive sucking habits (NNSHs, ie, sucking pacifiers or fingers) and maxillofacial growth anomalies in the general population has been widely described. Because maturation of sucking abilities is not fully achieved in very preterm infants (<32 weeks' gestation), neonatal services worldwide rely on the use of pacifiers to promote the development of adequate sucking reflexes, possibly prolonging NNSHs during infancy.

OBJECTIVE

We aimed to describe the frequency and to identify factors associated with NNSHs at age 2 years in very preterm children.

METHODS

The study was based on data from EPIPAGE-2, a French national prospective cohort study of preterm births during 2011 that included 2593 children born between 24 and 31 weeks' gestation. The primary outcome was NNSHs at 2 years. Multivariable log-linear regression models with generalized estimation equations were used to study the association between the characteristics studied and NNSHs. Multiple imputations were used to take into account missing data.

RESULTS

The frequency of NNSHs was 69% in the overall sample but higher among girls (adjusted risk ratio [RR] 1.12, 95% confidence interval [CI] 1.05, 1.17), children born from multiple pregnancies (eg, twins/triplets) (RR 1.07, 95% CI 1.00, 1.11), children who were fed by nasogastric tube (RR 1.07, 95% CI 1.01, 1.13), or those who benefitted from developmental care programmes (RR 1.10, 95% CI 1.02, 1.19). The NNSHs frequency was lower if mothers were not born in France (RR 0.70, 95% CI 0.64, 0.77), children had 2 or more older siblings (RR 0.88, 95% CI 0.82, 0.96), or children were breast-fed at discharge (RR 0.90, 95% CI 0.85, 0.95).

CONCLUSIONS

NNSHs at 2 years seemed associated with cultural background, development care programmes, and breast feeding. Whether NNSHs at 2 years among very preterm children are associated with future maxillofacial growth anomalies deserves further attention.

Non-pharmaceutical intervention and pain management situation for neonatal analgesia

Neonatal pain management is an important issue which should have great attention. More and more researches have proved that neonates can feel pain when undergoes painful procedures such as vaccination, heel stick, and so on, and it will result in short-term and long-term outcomes. So it is very important to manage neonatal pain. This article summarized some non-pharmaceutical interventions, including sucrose or glucose, non-nutritional sucking (NNS), breastfeeding, facilitated tucking (FT), kangaroo mother care (KMC), swaddling, heel warming, sensorial saturation (SS), and music therapy, which showed obvious effects for neonatal pain. In addition, this article summarized the progress of neonatal pain intervention in various countries and showed that many countries have not paid enough attention to this problem, while some countries have carried out promotion programs for neonatal pain management which give some clinical enlightenment to our country that we need to pay more attention to this problem.

Maternal psychosocial predictors of pacifier use in a mother-infant interaction task: An observational study from the MPEWS pregnancy cohort

The prevalence of pacifier use is high but when it occurs outside of the recommended sleep context, it becomes more controversial. Using 211 mother-infant dyads recorded as part of the Mercy Pregnancy and Emotional Wellbeing Study, we examined the maternal psychosocial predictors of pacifier use within an interaction task (i.e., ten minutes face-to-face followed by 30-minutes unstructured play). Predictors included maternal emotional availability measured with the Emotional Availability Scales; depression measured by the Structured Clinical Interview for the DSM-IV-TR Clinician Version; and maternal history of childhood trauma measured by the Childhood Trauma Questionnaire. An unadjusted odds ratio demonstrated that women classified as non-emotionally available to their infants were three-and-a-half-times more likely to use a pacifier. Multivariate logistic regression including all maternal psychosocial predictors demonstrated that even when adjusting for cessation of breastfeeding, maternal emotional availability remained the only significant predictor of pacifier use. This is the first time that predictors of pacifier use have been examined with a sample of clinically depressed women, as well as women with childhood trauma history. The results provide preliminary evidence that women who are not emotionally available might be more likely to rely on a pacifier during mother-infant interaction.

Development of locally relevant clinical guidelines for procedure-related neonatal analgesic practice in Kenya: a systematic review and meta-analysis

Background Increasing numbers of neonates are undergoing painful procedures in low-income and middle-income countries, with adequate analgesia seldom used. In collaboration with a multi-disciplinary team in Kenya, we aimed to establish the first evidence-based guidelines for the management of routine procedure-related neonatal pain that consider low-resource hospital settings.

METHODS

We did a systematic review by searching MEDLINE, Embase, CINAHL, and CENTRAL databases for studies published from Jan 1, 1953, to March 31, 2019. We included data from randomised controlled trials using heart rate, oxygen saturation (SpO2), premature infant pain profile (PIPP) score, neonatal infant pain scale (NIPS) score, neonatal facial coding system score, and douleur aiguë du nouveau-né scale score as pain outcome measures. We excluded studies in which neonates were undergoing circumcision or were intubated, studies from which data were unextractable, or when pain was scored by non-trained individuals. We did a narrative synthesis of all studies, and meta-analysis when data were available from multiple studies comparing the same analgesics and controls and using the same outcome measures. 17 Kenyan health-care professionals formed our clinical guideline development panel, and we used the Grading of Recommendations, Assessment, Development and Evaluation framework and the panel's knowledge of the local health-care context to guide the guideline development process. This study is registered with PROSPERO, CRD42019126620.

FINDINGS

Of 2782 studies assessed for eligibility, data from 149 (5%) were analysed, with 80 (3%) of these further contributing to our meta-analysis. We found a high level of certainty for the superiority of breastfeeding over placebo or no intervention (standardised mean differences [SMDs] were -1·40 [95% CI -1·96 to -0·84] in PIPP score and -2·20 [-2·91 to -1·48] in NIPS score), and the superiority of oral sugar solutions over placebo or no intervention (SMDs were -0·38 [-0·61 to -0·16] in heart rate and 0·23 [0·04 to 0·42] in SpO2). We found a moderate level of certainty for the superiority for expressed breastmilk over placebo or no intervention (SMDs were -0·46 [95% CI -0·87 to -0·05] in heart rate and 0·48 [0·20 to 0·75] in SpO2). Therefore, the panel recommended that breastfeeding should be given as first-line analgesic treatment, initiated at least 2 min pre-procedure. Given contextual factors, for neonates who are unable to breastfeed, 1-2 mL of expressed breastmilk should be given as first-line analgesic, or 1-2 mL of oral sugar (≥10% concentration) as second-line analgesic. The panel also recommended parental presence during procedures with adjunctive provision of skin-to-skin care, or non-nutritive sucking when possible.

INTERPRETATION

We have generated Kenya's first neonatal analgesic guidelines for routine procedures, which have been adopted by the Kenyan Ministry of Health, and have shown a framework for clinical guideline development that is applicable to other low-income and middle-income health-care settings.

Modified Sensory Stimulation Using Breastmilk for Reducing Pain Intensity in Neonates in Indonesia: A Randomized Controlled Trial

PURPOSE

Several studies have shown that oral sucrose reduces pain in newborns. However, sucrose has no efficacy in eliminating pain and long-term effects remain unclear. Breast milk may be useful as an alternative, safe sweet solution. Sensorial saturation (SS) is a multisensory analgesic non-pharmacological treatment, which includes touch and sounds as distractors. This study aimed to compare the analgesic effects of SS with sucrose (SSS), SS with breast milk (SSB), and oral sucrose alone (S24%) in neonates undergoing venipuncture.

DESIGN AND METHODS

This was a randomized controlled trial conducted on 108 neonates who underwent venipuncture at neonatology wards. All babies were randomly assigned to one of three groups: two intervention groups and one control group. Pain response was assessed using the premature infant pain profile-revised (PIPP-R). Data analysis was conducted using the Kruskal-Wallis test and Mann-Whitney U test.

RESULTS

SSB and SSS were more effective than S24% (p = 0.001). No difference was observed between SSB and SSS (p = 0.669).

CONCLUSION

Multisensory stimulation is more effective in reducing pain than unimodal (oral sucrose) analgesia. Breast milk can be used as a sensory gustatory stimulus in multisensory stimulation to reduce pain intensity in neonates, and demonstrates a similar analgesic effect to sucrose.

PRACTICE IMPLICATIONS

The study findings suggest that neonatal nurses could use SSB for management of pain. This intervention could serve as an effective, inexpensive, and safe non-pharmacological analgesic. Additional testing of this intervention is warranted to support its use as an evidence-based pain reduction approach.

A Comparison of Pain Scores in Neonatal Circumcision with or without Local Anesthesia in Jos, Nigeria

Introduction:

Neonatal circumcisions are commonly performed in Nigeria, most often without anesthesia. The aim of this study was to determine whether anesthesia was required for neonatal circumcision.

Materials and Methods:

All new-born male neonates presenting for routine circumcision were considered for inclusion in the study. This was a randomized control study, comparing pain scores during circumcision with local anesthesia or without local anesthesia. A total of 72 neonates were randomly assigned to the two groups using computer-generated random numbers, with 36 in each group. The neonates were not matched for age or weight. All the anesthetic procedures and circumcisions were performed in identical manner by the principal investigators using the plastic bell technique. Approval for the study was obtained from the Research Ethics Committee of the hospital. Written voluntary informed consent was obtained from the parents of the neonates.

Results:

The mean age and weight of the neonates in the study were 17 ± 2 days and 3.2 ± 0.68 kg, respectively. The mean Neonatal/Infant pain score was 4.8 in the local anesthesia group and 6.0 in those without anesthesia. The mean transcutaneous PO₂ was 90.47 ± 7.53 in those with anesthesia compared to 85.83 ± 5.61 in those without anesthesia. The mean heart rate was 133.88 ± 35.00 beats/min in the anesthesia group compared to 152.11 ± 79.80 in those without anesthesia. Neonates circumcised without local anesthesia had higher respiratory rate compared to those circumcised with local anesthesia.

Conclusion:

Neonates circumcised without local anesthesia had higher mean pain scores, heart rate, lower oxygen saturation and increased mean respiratory rate than those that had local anesthesia. Local anesthesia should be routinely used during neonatal circumcision.

Evaluation of the Reliability and Validity of the Behavioral Indicators of Infant Pain Scale in Chinese Neonates

BACKGROUND

Behavioral Indicators of Infant Pain scale (BIIP) has been shown to be a good tool to assess pain in infants.

AIMS

This paper aimed to translate BIIP into Chinese and evaluate its reliability and validity for neonates in China.

DESIGN

A prospective observational study. SETTING AND PARTICIPANTS: A convenience sample of 396 neonates (preterm and term infants) were recruited from neonatal intensive care units in China from July to October 2016.

METHODS

The BIIP was translated and adjusted for semantic adaption.396 neonates were assessed during 3 phases of blood collection from an artery/vein. A video camera was positioned for a close-up view of the face and body. The neonates' pain was rated independently by 2 nurses who were trained and familiar with the Chinese version of BIIP (C-BIIP)and FLACC (Facial expression, Legs, Activity, Crying and Consolability).

RESULTS

The internal consistency were 0.904 (preterm) and 0.895 (term). The test-retest reliability were 0.947 (preterm) and 0.938 (term) and the interclass correlation coefficients were 0.921 to 0.959 (preterm) and 0.921 to 0.959 (term). The correlations between the C-BIIP and FLACC were high (preterm: r = 0.948, term: r = 0.896). Using the C-BIIP, the 3 phases of blood collection were found to be statistically different (preterm: F = 635.76, term: F = 675.54; P < 0.001), which showed that the construct validity of C-BIIP was good.

CONCLUSION

The BIIP is a reliable and valid tool to assess pain in term and preterm neonates in China.

"Holding-Cuddling" and Sucrose for Pain Relief During Venepuncture in Newborn Infants: A Randomized, Controlled Trial (CÂSA)

Objectives: Oral sucrose is commonly used to provide analgesia to neonates during painful procedures, such as venepuncture. The additional benefits of reducing pain during venepuncture when oral sucrose is combined with nonpharmacological strategies have not been extensively studied. This randomized controlled trial compared the efficacy of oral sucrose with nonnutritive sucking vs. oral sucrose with nonnutritive sucking plus "holding-cuddling" for pain management during venepuncture in term infants from birth to 3 months of life. Methods: Seventy-eight infants were equally randomized to receive 24% oral sucrose with nonnutritive sucking (control group) or 24% oral sucrose with nonnutritive sucking plus "holding-cuddling" (being held in a secure, cuddling position; experimental group) before venepuncture. Behavioral response to pain was measured by the 0-10 ranking scale "acute pain for neonates (APN)" at 30 and 60 s after venepuncture. Results: Within the study sample, APN scores were ≥ 2 for 32/68 (47%) infants. "Holding-cuddling" did not significantly reduce mean APN scores at 30 and 60 s, but the rate of infants experiencing a high pain score (APN ≥ 8) at 60 s after the venepuncture was significantly lower in the experimental group compared to controls [4/34 vs. 12/34 (p = 0.04)]. Conclusions: Venepuncture is a painful procedure in newborn and young infants. The implementation of behavioral strategies in association with oral sucrose may mitigate pain during this procedure. Clinical Trial Registration: This trial was registered at http://clinicaltrials.gov/ (NCT number 02803723).

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.

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

INTRODUCTION

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

MATERIALS AND METHODS

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

RESULTS

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

CONCLUSIONS

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

Infant Analgesia With a Combination of Breast Milk, Glucose, or Maternal Holding

OBJECTIVES

We studied neonatal cortical brain response to 4 types of nonpharmacological analgesia (oral glucose, expressed breast milk, maternal holding plus oral glucose, breastfeeding). We aimed to assess the differential effect of oral solutions (glucose, breast milk) given alone or combined with the maternal-infant relationship (holding, breastfeeding).

METHODS

Eighty healthy term newborns undergoing a heel stick were randomly assigned to 4 parallel groups of 20 infants each: group 1, infants received a glucose solution on a changing table; group 2, infants received expressed breast milk on a changing table; group 3, infants received a glucose solution in their mothers' arms; and group 4, infants were breastfed by their mothers. Cortical activation in parietal, temporal, and frontal cortices was assessed by multichannel near-infrared spectroscopy. Pain expression was also evaluated.

RESULTS

Oral glucose alone or combined with maternal holding was associated with no cortical activation during heel stick. Expressed breast milk was associated with localized bilateral activation of somatosensory and motor cortices (P < .01). Breastfeeding was associated with extensive bilateral activation of somatomotor, somatosensory, and right parietal cortices (P < .01). Pain expression was lower with the maternal-infant relationship (P = .007).

CONCLUSIONS

Oral glucose, either alone or combined with maternal holding, appears to block or weaken cortical pain processing. Breast milk alone is associated with localized cortical activation. Breastfeeding is associated with extensive activation and may act by extending cortical processing. Maternal relationship, both combined with oral glucose and in breastfeeding, shows the greatest analgesic effect, although the neural patterns involved are distributed differently.

Comparison of the Efficacy of Oral 25% Glucose with Oral 24% Sucrose for Pain Relief during Heel Lance in Preterm Neonates: A Double Blind Randomized Controlled Trial

AIM

To study the analgesic effect of oral 25% glucose as compared with oral 24% sucrose during heel lance in preterm neonates.

METHODS

Stable preterm neonates within first 48 hours of life were randomized to receive either 24% sucrose or 25% glucose before heel lance. Primary outcome assessed was painful response by the Premature Infant Pain Profile (PIPP) score at 30 seconds after heel lance, and the secondary outcome was immediate adverse events associated with the administration of two solutions and duration of crying immediately following the procedure.

RESULTS

A total of 94 neonates were randomly assigned into 24% sucrose and 25% glucose group. The baseline characteristics between the two groups were comparable. No significant difference was observed between the two study groups with respect to PIPP scores, duration of crying and rate of adverse events.

CONCLUSIONS

When assessed by PIPP score, 25% glucose and 24% sucrose provided comparable analgesia during heel lance in preterm neonates.

Effects of combined oral sucrose and nonnutritive sucking (NNS) on procedural pain of NICU newborns, 2001 to 2016: A PRISMA-compliant systematic review and meta-analysis

BACKGROUND

Both oral sucrose (OS) and nonnutritive sucking (NNS) are effective nonpharmacological methods to alleviate procedures pain in neonatal intensive care unit (NICU) newborns when they were used alone, but the combined effect of OS+NNS remains controversial. So, we conducted this study to evaluate the efficiency of NNS combined with oral sucrose on pain relief in NICU newborns undergoing painful procedures.

METHODS

We searched PubMed, Ovid (Medline), Embase (Medline), Cochrane Central Library, and other resources such as Google Scholar, bibliographies of included literatures for all available articles. Two reviewers screened literatures and extracted data independently. The fixed effects model was used to pool the results using Reviewer Manager (RevMan) 5.3. As each study included in our meta-analysis had been approved by Ethics Committee or institutional review board, thus our study did not need ethical approval.

RESULTS

Seven randomized controlled trials, including 599 participants, were contained in our meta-analysis. The combination of oral sucrose and NNS is associated with reduced pain scores (mean difference [MD], -0.52; 95% confidence interval [CI], -0.68 to -0.36); shortened crying time (MD,-0.92; 95% CI, -1.39 to -0.44); but the 2 groups did not differ significantly in reducing bradycardia (MD, 0.73; 95% CI, 0.32-1.68), tachycardia (MD, 0.65; 95% CI, 0.38-1.10), or desaturations (MD, 0.73; 95% CI, 0.32-1.68).

CONCLUSION

The pooled evidence indicates that the combination measures may serve as an evidence-based guideline for pain relief among patients having minor pain. Besides, it also indicates that OS combined with NNS can be an alternative for better prevention and management of procedure pain in NICU newborns. Nevertheless, the results may be limited due to incomplete data, and thus, more randomized controlled trials or well-designed studies are required to determine the effects of OS+NNS in the future.

Anterior Open Bite In 27 Months Old Children after Use of a Novel Pacifier - A Cohort Study

OBJECTIVES

The aim of the present cohort study was to evaluate the influence of a novel pacifier on the first formation of malocclusion, the anterior open bite in children.

STUDY DESIGN

129 newborn children whose parents had decided to use pacifiers were randomly attributed to two experimental groups (D=Dentistar, n=56, Novatex, Pattensen, Germany; N=NUK, n=73, Mapa, Zeven, Germany). Children (n=42) who did not use a pacifier were not randomized and served as reference (C). Primary outcome was the presence of anterior open bite. It was hypothesized that D would result in lower incidence when compared to N. At the age of 27 months the children were examined with respect to anterior open bite. Fisher's exact test served to detect significant differences between groups D and N (SPSS 22.0).

RESULTS

121 children with a mean age of 26.7 months were included in the final analysis (D: n=45; N: n=42; C: n=34). In group D three children (6.7%) showed an anterior open bite. The respective values were 21 (50.0%) for N and 0 for C. The results for group D compared to N were significantly different (chi(2)-test, p<0.001).

CONCLUSION

In comparison to a commonly used pacifier the novel one causes significantly less anterior open bites.

Pain-relieving agents for infantile colic

BACKGROUND

Infantile colic is a common disorder in the first months of life, affecting somewhere between 4% and 28% of infants worldwide, depending on geography and definitions used. Although it is self limiting and resolves by four months of age, colic is perceived by parents as a problem that requires action. Pain-relieving agents, such as drugs, sugars and herbal remedies, have been suggested as interventions to reduce crying episodes and severity of symptoms.

OBJECTIVES

To assess the effectiveness and safety of pain-relieving agents for reducing colic in infants younger than four months of age.

SEARCH METHODS

We searched the following databases in March 2015 and again in May 2016: CENTRAL, Ovid MEDLINE, Embase and PsycINFO, along with 11 other databases. We also searched two trial registers, four thesis repositories and the reference lists of relevant studies to identify unpublished and ongoing studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs evaluating the effects of pain-relieving agents given to infants with colic.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures of The Cochrane Collaboration.

MAIN RESULTS

We included 18 RCTs involving 1014 infants. All studies were small and at high risk of bias, often presenting major shortcomings across multiple design factors (e.g. selection, performance, attrition, lack of washout period).Three studies compared simethicone with placebo, and one with Mentha piperita; four studies compared herbal agents with placebo; two compared sucrose or glucose with placebo; five compared dicyclomine with placebo; and two compared cimetropium - one against placebo and the other at two different dosages. One multiple-arm study compared sucrose and herbal tea versus no treatment. Simethicone. Comparison with placebo revealed no difference in daily hours of crying reported for simethicone at the end of treatment in one small, low-quality study involving 27 infants. A meta-analysis of data from two cross-over studies comparing simethicone with placebo showed no difference in the number of of infants who responded positively to treatment (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.73 to 1.23; 110 infants, low-quality evidence).One small study (30 participants) compared simethicone with Mentha piperita and found no difference in crying duration, number of crying episodes or number of responders. Herbal agents. We found low-quality evidence suggesting that herbal agents reduce the duration of crying compared with placebo (mean difference (MD) 1.33, 95% CI 0.71 to 1.96; three studies, 279 infants), with different magnitude of benefit noted across studies (I² = 96%). We found moderate-quality evidence indicating that herbal agents increase response over placebo (RR 2.05, 95% CI 1.56 to 2.70; three studies, 277 infants). Sucrose. One very low-quality study involving 35 infants reported that sucrose reduced hours spent crying compared with placebo (MD 1.72, 95% CI 1.38 to 2.06). Dicyclomine. We could consider only one of the five studies of dicyclomine (48 infants) for the primary comparison. In this study, more of the infants given dicyclomine responded than than those given placebo (RR 2.50, 95% CI 1.17 to 5.34). Cimetropium bromide. Data from one very low-quality study comparing cimetropium bromide with placebo showed reduced crying duration among infants treated with cimetropium bromide (MD -30.20 minutes per crisis, 95% CI -39.51 to -20.89; 86 infants). The same study reported that cimetropium increased the number of responders (RR 2.29, 95% CI 1.44 to 3.64).No serious adverse events were reported for all of the agents considered, with the exception of dicyclomine, for which two of five studies reported relevant adverse effects (longer sleep 4%, wide-eyed state 4%, drowsiness 13%).

AUTHORS' CONCLUSIONS

At the present time, evidence of the effectiveness of pain-relieving agents for the treatment of infantile colic is sparse and prone to bias. The few available studies included small sample sizes, and most had serious limitations. Benefits, when reported, were inconsistent.We found no evidence to support the use of simethicone as a pain-relieving agent for infantile colic.Available evidence shows that herbal agents, sugar, dicyclomine and cimetropium bromide cannot be recommended for infants with colic.Investigators must conduct RCTs using standardised measures that allow comparisons among pain-relieving agents and pooling of results across studies. Parents, who most often provide the intervention and assess the outcome, should always be blinded.

Sucrose for analgesia in newborn infants undergoing painful procedures

BACKGROUND

Administration of oral sucrose with and without non-nutritive sucking is the most frequently studied non-pharmacological intervention for procedural pain relief in neonates.

OBJECTIVES

To determine the efficacy, effect of dose, method of administration and safety of sucrose for relieving procedural pain in neonates as assessed by validated composite pain scores, physiological pain indicators (heart rate, respiratory rate, saturation of peripheral oxygen in the blood, transcutaneous oxygen and carbon dioxide (gas exchange measured across the skin - TcpO2, TcpCO2), near infrared spectroscopy (NIRS), electroencephalogram (EEG), or behavioural pain indicators (cry duration, proportion of time crying, proportion of time facial actions (e.g. grimace) are present), or a combination of these and long-term neurodevelopmental outcomes.

SEARCH METHODS

We used the standard methods of the Cochrane Neonatal. We performed electronic and manual literature searches in February 2016 for published randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library, Issue 1, 2016), MEDLINE (1950 to 2016), EMBASE (1980 to 2016), and CINAHL (1982 to 2016). We did not impose language restrictions.

SELECTION CRITERIA

RCTs in which term or preterm neonates (postnatal age maximum of 28 days after reaching 40 weeks' postmenstrual age), or both, received sucrose for procedural pain. Control interventions included no treatment, water, glucose, breast milk, breastfeeding, local anaesthetic, pacifier, positioning/containing or acupuncture.

DATA COLLECTION AND ANALYSIS

Our main outcome measures were composite pain scores (including a combination of behavioural, physiological and contextual indicators). Secondary outcomes included separate physiological and behavioural pain indicators. We reported a mean difference (MD) or weighted MD (WMD) with 95% confidence intervals (CI) using the fixed-effect model for continuous outcome measures. For categorical data we used risk ratio (RR) and risk difference. We assessed heterogeneity by the I(2) test. We assessed the risk of bias of included trials using the Cochrane 'Risk of bias' tool, and assessed the quality of the evidence using the GRADE system.

MAIN RESULTS

Seventy-four studies enrolling 7049 infants were included. Results from only a few studies could be combined in meta-analyses and for most analyses the GRADE assessments indicated low- or moderate-quality evidence. There was high-quality evidence for the beneficial effect of sucrose (24%) with non-nutritive sucking (pacifier dipped in sucrose) or 0.5 mL of sucrose orally in preterm and term infants: Premature Infant Pain Profile (PIPP) 30 s after heel lance WMD -1.70 (95% CI -2.13 to -1.26; I(2) = 0% (no heterogeneity); 3 studies, n = 278); PIPP 60 s after heel lance WMD -2.14 (95% CI -3.34 to -0.94; I(2) = 0% (no heterogeneity; 2 studies, n = 164). There was high-quality evidence for the use of 2 mL 24% sucrose prior to venipuncture: PIPP during venipuncture WMD -2.79 (95% CI -3.76 to -1.83; I(2) = 0% (no heterogeneity; 2 groups in 1 study, n = 213); and intramuscular injections: PIPP during intramuscular injection WMD -1.05 (95% CI -1.98 to -0.12; I(2) = 0% (2 groups in 1 study, n = 232). Evidence from studies that could not be included in RevMan-analyses supported these findings. Reported adverse effects were minor and similar in the sucrose and control groups. Sucrose is not effective in reducing pain from circumcision. The effectiveness of sucrose for reducing pain/stress from other interventions such as arterial puncture, subcutaneous injection, insertion of nasogastric or orogastric tubes, bladder catherization, eye examinations and echocardiography examinations are inconclusive. Most trials indicated some benefit of sucrose use but that the evidence for other painful procedures is of lower quality as it is based on few studies of small sample sizes. The effects of sucrose on long-term neurodevelopmental outcomes are unknown.

AUTHORS' CONCLUSIONS

Sucrose is effective for reducing procedural pain from single events such as heel lance, venipuncture and intramuscular injection in both preterm and term infants. No serious side effects or harms have been documented with this intervention. We could not identify an optimal dose due to inconsistency in effective sucrose dosage among studies. Further investigation of repeated administration of sucrose in neonates is needed. There is some moderate-quality evidence that sucrose in combination with other non-pharmacological interventions such as non-nutritive sucking is more effective than sucrose alone, but more research of this and sucrose in combination with pharmacological interventions is needed. Sucrose use in extremely preterm, unstable, ventilated (or a combination of these) neonates needs to be addressed. Additional research is needed to determine the minimally effective dose of sucrose during a single painful procedure and the effect of repeated sucrose administration on immediate (pain intensity) and long-term (neurodevelopmental) outcomes.

Strategies to minimize sedation in pediatric body magnetic resonance imaging

The high soft-tissue contrast of MRI and the absence of ionizing radiation make it a valuable tool for assessment of body pathology in children. Infants and young children are often unable to cooperate with awake MRI so sedation or general anesthesia might be required. However, given recent data on the costs and potential risks of anesthesia in young children, there is a need to try to decrease or avoid sedation in this population when possible. Child life specialists in radiology frequently use behavioral techniques and audiovisual support devices, and they practice with children and families using mock scanners to improve child compliance with MRI. Optimization of the MR scanner environment is also important to create a child-friendly space. If the child can remain inside the MRI scanner, a variety of emerging techniques can reduce the effect of involuntary motion. Using sequences with short acquisition times such as single-shot fast spin echo and volumetric gradient echo can decrease artifacts and improve image quality. Breath-holding, respiratory triggering and signal averaging all reduce respiratory motion. Emerging techniques such as radial and multislice k-space acquisition, navigator motion correction, as well as parallel imaging and compressed sensing reconstruction methods can further accelerate acquisition and decrease motion. Collaboration among radiologists, anesthesiologists, technologists, child life specialists and families is crucial for successful performance of MRI in young children.

To evaluate and compare the efficacy of combined sucrose and non-nutritive sucking for analgesia in newborns undergoing minor painful procedure: a randomized controlled trial

OBJECTIVE

The objective of this study was to evaluate and compare the efficacy of combined sucrose and non-nutritive sucking (NNS) for analgesia in newborn infants undergoing heel-stick procedures.

STUDY DESIGN

This randomized control trial was conducted in the neonatal intensive care unit of a tertiary care hospital over a period of 1 year. One hundred and eighty full-term neonates with birth weight >2200 g and age >24 h were randomized to one of four interventions administered 2 min before the procedure: 2 ml of 30% sucrose (group I, n=45) or NNS (group II, n=45) or both (group III, n=45) or none (group IV, n=45). Primary outcome was composite score based on Premature Infant Pain Profile (PIPP) score.

RESULT

Baseline variables were comparable among the groups. Median (interquartile range) PIPP score was 3 (2 to 4) in group III as compared with 7 (6.5 to 8) in group I, 9 (7 to 11) in group II and 13 (10.5 to 15) in group IV. Group III had significant decrease in the median PIPP score compared with other groups (P=0.000). Median PIPP score also decreased significantly with any intervention as compared with no intervention (P=0.000).

CONCLUSION

Sucrose and/or NNS are effective in providing analgesia in full-term neonates undergoing heel-stick procedures, with the combined intervention being more effective compared with any single intervention.

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.

[Non-pharmaceutical measures, topical analgesics and oral administration of glucose in pain management: Austrian interdisciplinary recommendations on pediatric perioperative pain management]

Non-pharmaceutical procedures are increasingly being used in pediatric pain therapy in addition to pharmaceutical procedures and have a supporting function. This article describes the non-pharmaceutical procedures which have an influence on perioperative and posttraumatic pain in children and adolescents. Prerequisites for every adequate pain therapy are affection, imparting a feeling of security, distraction and the creation of a child-oriented environment. Topical analgesics are indicated for application to intact skin for surface anesthesia. For a safe use consideration must be given to the duration of application, the dose and the maximum area of skin treated in an age-dependent manner. For simple but painful procedures in premature infants, neonates and infants, pain can be effectively reduced by the oral administration of glucose. The positive effect is guaranteed particularly for the use in a once only pain stimulation. Non-nutritive sucking, swaddling, facilitated tucking and kangaroo mother care, for example can be used as supportive measures during slightly painful procedures. There is insufficient evidence for a pain reducing effect in older infants and small children. Physical therapeutic procedures can be used as accompanying measures for acute pain and are individually adapted. However, the limited amount of currently available data is insufficient to make a critical scientific assessment of the individual measures. The effects can, however, be observed in the daily routine practice. Psychological methods can facilitate coping with pain. In situations with mental and psychiatric comorbidities or psychosocial impairment, a psychologist should be consulted. Acupuncture and hypnosis are also a meaningful addition within the framework of multimodal pain therapy.

Analgesic, anxiolytic and anaesthetic effects of melatonin: new potential uses in pediatrics

Exogenous melatonin is used in a number of situations, first and foremost in the treatment of sleep disorders and jet leg. However, the hypnotic, antinociceptive, and anticonvulsant properties of melatonin endow this neurohormone with the profile of a drug that modulates effects of anesthetic agents, supporting its potential use at different stages during anesthetic procedures, in both adults and children. In light of these properties, melatonin has been administered to children undergoing diagnostic procedures requiring sedation or general anesthesia, such as magnetic resonance imaging, auditory brainstem response tests and electroencephalogram. Controversial data support the use of melatonin as anxiolytic and antinociceptive agents in pediatric patients undergoing surgery. The aim of this review was to evaluate available evidence relating to efficacy and safety of melatonin as an analgesic and as a sedative agent in children. Melatonin and its analogs may have a role in antinociceptive therapies and as an alternative to midazolam in premedication of adults and children, although its effectiveness is still controversial and available data are clearly incomplete.

Oral glucose solution to alleviate pain induced by intramuscular injections in preterm infants

PURPOSE

The purpose was to assess the effectiveness of 5% oral glucose solution in reducing pain in preterm infants during intramuscular injection.

DESIGN AND METHODS

We conducted a prospective, randomized, controlled, unblinded trial to investigate the effect of glucose solution on the pain of intramuscular injection in preterm infants (N = 80).

RESULTS

Infants who received oral glucose had significantly lower pain scores (p < .001), less crying time (p < .001), higher oxygen saturation (p < .001), and lower heart rate after compared with during the procedure (p = .02).

PRACTICE IMPLICATIONS

Our results suggest that oral glucose, even if used in the lowest dose, may have a pain-relieving effect in preterm infants if administered pre-procedure.

A comparative study on the efficacy of glucose and sucrose on the vaccination pain: a randomized controlled clinical trial

OBJECTIVES

This study was performed to compare the effectiveness of two analgesics for the management of vaccination pain.

MATERIALS AND METHODS

A total of 90 neonates to be vaccinated against Hepatitis B were assigned to Glucose, Sucrose and control groups at Shahid Mostafa Khomini hospital. 2cc oral Glucose 25% and 2cc oral Sucrose 25% with Syringe were given for 30 sec then 2 min later Hepatitis-B vaccine injected by vaccinator and pain intensity measured by Neonatal Infant Pain Scale (NIPS) during 1-2 min. The third group (control) no intervention was performed. The collected data were analysed by SPSS18 Software and ANOVA and LSD tests were used.

RESULTS

Research results showed that there were no significant differences between groups in term of Apgar score, delivery type, sex, head circumstance, weight and height. By comparison of pain severity in two groups, mean and Standard deviation of pain, group that received Glucose solution had more intensity than Sucrose group (3 ± 1.66 vs. 2.90 ± 1.44), but this difference was not significant statistically (p=0.78). Comparison of pain intensity in control and intervention groups showed that the pain intensity in control group is higher than intervention groups (p<0.001).

CONCLUSION

Patients who received Glucose or Sucrose had lower pain intensity in comparison with the other. The pain intensity in patients who received sucrose was less than the glucose group, but this difference was not significant statistically.

[Pain in neonatology. Non-pharmacological treatment]

Diagnostic and therapeutic skin-breaking procedures have become ubiquitous in current medical practice and neonatology does not constitute an exception. One of the main sources of neonatal pain is procedure-induced pain. It has recently become clear that pain prevention must be a health care priority. Non-pharmacological approaches constitute a first option for the analgesia of common procedures performed in neonatology. This article reviews the non-pharmacological treatments most frequently used in this context: swaddling, tucking, containment, sweet solutions, non-nutritive sucking (NNS), breastfeeding analgesia, breast milk and music. In practice, the dose of 1 to 2mL of 24% or 30% sucrose solution or 30% glucose solution immediately followed by NNS can be given for minor painful procedures in term neonates or those weighing more than 2500g. In the preterm, 0.3mL of a sweet solution (sucrose or glucose) can be given for infants weighing less than 1500g and 0.5mL for those weighing between 1500 and 2500g. The synergistic effect of sweet solutions and NNS has been clearly shown and thus their association is largely justified in practice. For breast-fed term neonates, breastfeeding can be given to sooth procedure-induced pain. All these non-pharmacological options can be effective to relieve pain from minor or moderate procedures. However, when more painful procedures are performed, stronger analgesics must be used.

Cerebral hemodynamic changes and pain perception during venipuncture: is glucose really effective?

Newborns are exposed to a considerable number of painful stimuli. This study is aimed to investigate the effects of 30% glucose solution and nonnutritive sucking on pain perception during venipuncture. Twenty-five term infants were randomized as receiving 30% dextrose (group 1) or sterile water (group 2). Neonatal Infant Pain Scale scores, skin conductance algesimeter recordings, and near-infrared spectroscopy measurements were recorded during the procedure. Neonatal Infant Pain Scale and skin conductance algesimeter results were decreased in both groups from that during venipuncture to after the procedure. Group 1 had lower Neonatal Infant Pain Scale scores compared with group 2 after venipuncture, different from the skin conductance algesimeter, where no difference was observed between groups. In group 1, cerebral blood volume increased after venipuncture. Glucose does not attenuate the Neonatal Infant Pain Scale score and skin conductance algesimeter index during venipuncture, but it leads to a lower Neonatal Infant Pain Scale score after venipuncture unlike the skin conductance algesimeter index, which was not lowered.

Dummy (pacifier) use and sudden infant death syndrome: potential advantages and disadvantages

The large decline in deaths due to the sudden infant death syndrome (SIDS) in the last 20 years in many countries is largely due to risk-reduction advice resulting from observational studies that examined the relationship between infant care practices and SIDS. Most of this advice remains largely uncontroversial and educators and researchers in this field are in agreement as to the specific recommendations that should be given to parents and health professionals. However, advice surrounding the apparent protective effect of dummies (also known as pacifiers) has been controversial. Several systematic reviews have demonstrated a strong association between the lack of a pacifier being used by the infant for the final sleep and SIDS, but it is not clear how pacifiers confer protection or if this is a marker for something as yet unmeasured. The Epidemiology and Physiology Working Groups of the International Society for the Study and Prevention of Perinatal and Infant Death (ISPID) are comprised of leading SIDS researchers with an objective to provide evidence-based position statements surrounding the factors associated with SIDS (http://www.ispid.org/) and risk-reduction strategies. The evidence, discussion and conclusions from these working groups regarding dummies (pacifiers) are described below to help inform this debate and describe the future evidence required so that we might find a common recommendation about dummies (pacifiers) and SIDS.

A systematic review and meta-analyses of nonsucrose sweet solutions for pain relief in neonates

BACKGROUND

Sucrose has been demonstrated to provide analgesia for minor painful procedures in infants. However, results of trials investigating other sweet solutions for neonatal pain relief have not yet been synthesized.

OBJECTIVE

To establish the efficacy of nonsucrose sweet-tasting solutions for pain relief during painful procedures in neonates.

METHOD

The present article is a systematic review and meta-analyses of the literature. Standard methods of the Cochrane Neonatal Collaborative Review Group were used. Literature searches were reviewed for randomized controlled trials investigating the use of sweet solutions, except sucrose, for procedural pain management in neonates. Outcomes assessed included validated pain measures and behavioural and physiological indicators.

RESULTS

Thirty-eight studies (3785 neonates) were included, 35 of which investigated glucose. Heel lancing was performed in 21⁄38 studies and venipuncture in 11⁄38 studies. A 3.6-point reduction in Premature Infant Pain Profile scores during heel lances was observed in studies comparing 20% to 30% glucose with no intervention (two studies, 124 neonates; mean difference -3.6 [95% CI -4.6 to -2.6]; P<0.001; I2=54%). A significant reduction in the incidence of cry after venipuncture for infants receiving 25% to 30% glucose versus water or no intervention was observed (three studies, 130 infants; risk difference -0.18 [95% CI -0.31 to -0.05]; P=0.008, number needed to treat = 6 [95% CI 3 to 20]; I2=63%).

CONCLUSIONS

The present systematic review and meta-analyses demonstrate that glucose reduces pain scores and crying during single heel lances and venipunctures. Results indicate that 20% to 30% glucose solutions have analgesic effects and can be recommended as an alternative to sucrose for procedural pain reduction in healthy term and preterm neonates.

Per-oral flexible laryngoscopy in awake neonates and infants: the 'pacifier' technique

BACKGROUND

It is common for ENT specialists to be called to neonatal intensive care units to assess neonates with suspected laryngomalacia. At Addenbrooke's Hospital, Cambridge, UK, it is standard practice to initially try to assess the larynx whilst the patient is awake. This can cause the patient to cry and become irritable, and can induce worry in the parents. A literature search revealed that numerous procedures have been successfully performed on neonates and infants whilst they were being pacified.

OBJECTIVES

This paper describes various procedures where pacification has been used effectively. Furthermore, it reports a pacification technique developed for per-oral flexible laryngoscopy in awake neonates and infants.

Oral sucrose and non-nutritive sucking goes some way to reducing pain during retinopathy of prematurity eye examinations

AIM

To evaluate the efficacy of oral sucrose combined with non-nutritive sucking for reducing pain associated with retinopathy of prematurity screening.

METHODS

This was a randomised controlled study of 64 infants undergoing eye examination for retinopathy of prematurity screening. Topical anaesthetic (Proparacaine; Alcaine(®) drop 0.5%: ALCON CANADA Inc., Mississauga, Canada) was applied 30 sec before the eye examination in all infants. The infants in intervention group (Group 1, n = 32) received 0.5 mL/kg of 24% sucrose with a pacifier. The control group (Group 2, n = 32) received 0.5 mL/kg of sterile water with a pacifier.

RESULTS

The groups had similar gestational ages (28.5 ± 2.8 weeks), mean birthweight (1304 ± 466 g) or corrected gestational age (35.4 ± 3.7 weeks) at examination. The intervention group had a significantly lower mean Premature Infant Pain Profile score during examination of the first eye, following insertion of the speculum (Group 1:13.7 ± 2.1 vs. Group 2:16.4 ± 1.8, p = 0.001).

CONCLUSION

Although sucrose combined with non-nutritive sucking modestly reduces pain scores during eye examinations, there is need to further studies to explore significant pain relief for infants undergoing retinopathy of prematurity screening.

Oral dextrose for analgesia in neonates during nasogastric tube insertion: a randomised controlled trial

AIM

This study aims to determine if oral dextrose solution can mitigate the pain response to nasogastric tube (NGT) insertion in neonates.

METHODS

The study was a double-blinded, placebo-controlled, randomised controlled trial. One hundred and fifty consecutive neonates were randomised into three groups to receive 25% dextrose (D25), or 10% dextrose (D10) or placebo (distilled water). An NGT was inserted after giving 2 mL of one of the solutions orally. Pain response was assessed using the Premature Infant Pain Profile (PIPP), and the duration of cry was noted within 60 s of the intervention. Total PIPP score, duration of cry, change in heart rate and oxygen saturation (SpO2 ) were compared among the three groups.

RESULTS

Neonates who received D25 had significantly lesser pain response to NGT insertion in terms of lower PIPP score (P < 0.05) and duration of cry (P = 0.001) compared to D10. There was a significantly smaller increase in heart rate and decrease in SpO2 (P < 0.05). In comparison with placebo, D10 significantly decreased duration of cry (P < 0.05) but not PIPP score.

CONCLUSION

Oral D25 was effective in reducing the pain response during NGT insertion in neonates when compared with oral D10 and placebo. Oral D10 was not found to have a potent analgesic effect for the same.

Pain management in neonates

Multiple lines of evidence suggest an increased sensitivity to pain in neonates. Repeated and prolonged pain exposure may affect the subsequent development of pain systems, as well as potentially contribute to alterations in long-term development and behavior. Despite impressive gains in the knowledge of neonatal pain mechanisms and strategies to treat neonatal pain acquired during the last 15 years, a large gap still exists between routine clinical practice and research results. Accurate assessment of pain is crucial for effective pain management in neonates. Neonatal pain management should rely on current scientific evidence more than the attitudes and beliefs of care-givers. Parents should be informed of pain relief strategies and their participation in the health care plan to alleviate pain should be encouraged. The need for systemic analgesia for both moderate and severe pain, in conjunction with behavioral/environmental approaches to pain management, is emphasized. A main sources of pain in the neonate is procedural pain which should always be prevented and treated. Nonpharmacological approaches constitute important treatment options for managing procedural pain. Nonpharmacological interventions (environmental and preventive measures, non-nutritive sucking, sweet solutions, skin-skin contact, and breastfeeding analgesia) can reduce neonatal pain indirectly by reducing the total amount of noxious stimuli to which infants are exposed, and directly, by blocking nociceptive transduction or transmission or by activation of descending inhibitory pathways or by activating attention and arousal systems that modulate pain. Opioids are the mainstay of pharmacological pain treatment but there are other useful medications and techniques that may be used for pain relief. National guidelines are necessary to improve neonatal pain management at the institutional level, individual neonatal intensive care units need to develop specific practice guidelines regarding pain treatment to ensure that all staff are familiar with the effects of the drugs being used and to guarantee access and safe administration of pain treatment to all neonates.

Sedation and analgesia in critically ill children

The interplay of pain, discomfort, and fear can cause agitation in critically ill children. Therefore, sedation and analgesia are essential components in the intensive care unit setting and are best managed with a multidisciplinary team approach. No one standard approach exists to assess and manage pain and anxiety. Many tools are available for the assessment of pain and sedation, but each tool has its advantages and disadvantages. Clinicians should consider adopting a validated tool for routine continuous assessment. Multiple pharmacological therapies are available to manage pain, anxiety, fear, and agitation. Dosing of these agents can be influenced by age-related pharmacokinetic and pharmacodynamic changes. Agents should be selected on the basis of the child's disease state, desired level of sedation, and cardiac and respiratory status.
