Magnetic noninvasive acupuncture for infant comfort (MAGNIFIC) - a single-blinded randomised controlled pilot trial

A scoping review of mechanisms of auricular acupuncture for treatment of pain

OBJECTIVES

Auricular acupuncture (AA) is becoming increasingly common in primary care clinics, emergency departments and peri-operatively for pain relief. Over the last decade, since the last comprehensive reviews were published, the literature has expanded. In this scoping review, we seek to document the efficacy of AA in treating both acute and chronic pain, describe the mechanism of action of AA in treating pain, and discuss how AA has been integrated into Western medicine to date.

METHODS

The authors performed a MEDLINE search inclusive of articles from 1966 to June 2023 including articles written in English identifying literature. We included human studies when more than 3 patients were included. Three hundred and fourteen unique articles were identified and 152 were selected by title screen. After abstract review, 117 were chosen for full-text review. Following full-text review, 33 articles were excluded and 21 added from references, totaling 105 articles included in our scoping review.

RESULTS

AA reduces pain severity in patients with both acute and chronic pain. The best studies in the acute settings have occurred in the peri-operative setting where sham AA is employed, multiple sessions of AA are given, and medication dosing is carefully monitored. In these cases, AA reduced pain and post-operative medications. In patients with chronic pain, multiple sessions of AA resulted not only in pain relief but also in improvements in function and disability. Literature suggests that AA works through multiple mechanisms with the most compelling data coupled to the autonomic nervous system and neuroendocrine system. Curriculums designed to teach AA and aid in implementation have been published.

CONCLUSION

AA is an accessible, effective means of pain relief. AA is relatively straightforward to learn, and protocols and curriculums exist to teach healthcare professionals this valuable skill. Overcoming implementation barriers, including patient education, are essential next steps.

Cardiovascular effects of auricular stimulation -a systematic review and meta-analysis of randomized controlled clinical trials

Background

The number of randomized controlled trials using auricular stimulation (AS) such as transauricular vagus nerve stimulation, or other auricular electrostimulation or auricular acupuncture or acupressure, in experimental and clinical settings, has increased markedly over the last three decades. This systematic review focusses on cardiovascular effects of auricular stimulation.

Methods and analysis

The following databases were searched: MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science, and Scopus Database. RCTs were reviewed that had been published in English and European languages. Data collection and analysis was conducted by two reviewers independently. Quality and risk assessment of included studies was performed and the meta-analysis of the effect of the most frequently assessed biomarkers.

Results

Altogether, 78 trials were included. 38 studies assessed heart rate (HR), 19 studies analyzed heart rate variability (HRV), 31 studies analyzed blood pressure (BP) and 7 studies were identified that measured oxygen saturation (O2), 2 studies on baroreflex sensitivity and 2 studies on skin conductance were evaluated in this review. 26 studies contained continuous data and were eligible for meta-analysis, 50 trials reported non continuous data and were evaluated descriptively. The overall quality of the studies was moderate to low. AS leads to a significant reduction of HR, the changes though were not considered an adverse reaction. Furthermore, when looking at HRV, AS was able to reduce the LF/HF ratio significantly compared to control procedures. No other cardiovascular parameters (blood pressure, oxygen saturation, baroreflex sensitivity) were changed significantly. AS produced only minor side effects in all trials.

Conclusion

AS can lead to clinically safe reduction of HR and changes in the LF/HF ratio of the HRV, which is presumably via an increase in vagal activity. More research is needed to clarify whether AS can be used to modulate tachycardia or indications with autonomic imbalance.

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.

Effect of Acupoint Stimulation on Controlling Pain from Heel Lance in Neonates: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

To evaluate the effect of acupoint stimulation compared to other interventions on pain control in neonates who underwent heel lance, we searched for randomized controlled trials across six databases (CINAHL, Cochrane Library, EMBASE, Medline, PubMed, and Web of Science) published up to January 2023. Studies comparing acupoint stimulation and other interventions for controlling heel lance pain in neonates were included. These reports measured at least one of the following variables: pain score, crying time, oxygenation saturation, heart rate, respiration rate, and duration of the procedure. The data were independently extracted by two authors, and the PRISMA guidelines for study selection were followed. A total of 79 articles were screened, and 10 studies, with results on 813 neonates, were included in the final selection. The pain scores recorded during the heel lance procedure were not significantly different between the acupoint stimulation cohort and the control cohort (SMD of -0.26, 95% confidence interval (CI) from -0.52 to 0.01; p = 0.06; I² = 68%). After processing the subgroup analyses, significant differences were found in the comparisons of acupuncture vs. usual care (SMD of -1.25, 95% CI from -2.23 to 0.27) and acupressure vs. usual care (SMD of -0.62, 95% CI from -0.96 to -0.28); nonsignificant differences were found in other comparisons. Our results demonstrate that acupoint stimulation may improve pain score during the heel lance procedure.

A randomized, placebo-controlled study of magnetic acupuncture for supplementary analgesia after laparoscopic appendectomy in children

PURPOSE

Magnetic acupuncture (MA) is a noninvasive technique potentially useful for postoperative pain reduction. While anecdotal case series have reported analgesic effects, this has not been systematically studied. We evaluated the analgesic properties of supplemental MA versus placebo and standard treatment in children who underwent laparoscopic appendectomy (LA).

METHODS

Children age 2-18 years who underwent LA for acute appendicitis were recruited from 2018 through 2020. Standardized postoperative pain medication including Ibuprofen, Acetaminophen, and narcotics were given as needed. Patients were randomized to 3 groups: Group 1 had adhesive acupuncture magnets placed on 5 predetermined meridian points for 48 h. Group 2 had corresponding non-magnetic adhesive metal disks placed in the same locations. Group 3 received no supplemental treatment. Pain was measured every 4 h using a 1-10 Visual-Analog-Scale (VAS). Cumulative demand of as-needed pain medication was calculated. Patients and families were handed open questionnaires upon discharge assessing satisfaction with treatment.

RESULTS

A total of 126 patients were randomized. Groups were similar in age and gender distribution. Differences of means of cumulative VAS scores were significantly lower for group 1 (8.0,SD5.2) compared to group 2 (12.8,SD4.4; -4.8[95%CI -7.1 to -2.5], p < 0.01), and group 3 (19.8,SD7.7; -11.8[95%CI -15.0 to -8.6], p < 0.01). Cumulative acetaminophen and ibuprofen use per patient during the entire hospital stay was lower for group 1 (1510 mg, 20 mg) than for group 2 (2950 mg, 1800 mg), and group 3 (6100 mg; 2300 mg), respectively. In contrast to groups 2 and 3, none of the patients in group 1 asked for narcotics. Patients were highly satisfied with MA.

CONCLUSIONS

Supplemental MA after LA in children had a beneficial effect on the postoperative pain perception and on-demand use of analgesics that could not be explained by placebo mechanism. MA is a safe, simple, and effective adjunct to standard postoperative care. Further studies are warranted.

Psychosocial and Neurobiological Vulnerabilities of the Hospitalized Preterm Infant and Relevant Non-pharmacological Pain Mitigation Strategies

Background: Preterm pain is common in the Neonatal Intensive Care Unit (NICU), with multiple invasive procedures occurring daily. Objective: To review the psychosocial and neurobiological vulnerabilities of preterm infants and to provide an updated overview of non-pharmacological strategies for acute procedural pain in hospitalized preterm infants. Methods: We utilized a narrative review methodology, which also included a synthesis of key pieces of published systematic reviews that are relevant to the current work. Results and Conclusions: Preterm infants are uniquely susceptible to the impact of painful procedures and prolonged separation from caregivers that are often inherent in a NICU stay. Non-pharmacological interventions can be efficacious for mitigating procedural pain for preterm infants. Interventions should continue to be evaluated with high quality randomized controlled trials, and should endeavor to take into account the neurobiological and psychosocial aspects of preterm vulnerability for pain prevention and management strategies.

Laser acupuncture versus oral glucose administration for pain prevention in term neonates: an observer-blinded non-inferiority randomized controlled clinical trial

BACKGROUND

Neonates undergoing intensive care are routinely submitted to minor painful procedures such as heel lances. Pharmacological treatment is limited in neonatal care and not recommended for minor painful interventions. Hence, non-pharmacological acute pain management is an important subject. Acupuncture could be a new strategy for neonatal pain prevention. Accordingly, the aim of the present study was to investigate whether laser acupuncture is non-inferior to oral sweet solutions in pain prevention.

METHODS

In total, 96 healthy term neonates were randomly assigned to receive either laser acupuncture with 10 mW at LI4 bilaterally (AG, acupuncture group) or 30% oral glucose solution (GG, glucose group) before heel lance for metabolic screening. The primary outcome was the difference in premature infant pain profile (PIPP) score between groups in a non-inferiority concept. Secondary outcomes were changes in heart rate and crying time.

RESULTS

Median (interquartile range) PIPP scores were comparable in the AG and GG (12 (10-14) vs 12 (9-14), p = 0.981). Nevertheless, the 95% confidence interval (CI) of location shift exceeded the predefined margin for non-inferiority of 1 (95% CI: -1.000006 to 1.000059). Heart rate was found to be significantly lower after intervention (p = 0.048) and after heel lance (p = 0.015) in the AG versus GG. There was no difference in crying time between groups (p = 0.890).

CONCLUSION

Laser acupuncture was not shown to be non-inferior to an oral glucose solution, possibly due to the higher than expected variability in PIPP scores within the studied groups. Future neonatal laser acupuncture studies for pain prevention with higher sample sizes are therefore warranted.

Non-pharmacological care for opioid withdrawal in newborns

BACKGROUND

The prevalence of substance use, both prescribed and non-prescribed, is increasing in many areas of the world. Substance use by women of childbearing age contributes to increasing rates of neonatal abstinence syndrome (NAS). Neonatal opioid withdrawal syndrome (NOWS) is a newer term describing the subset of NAS related to opioid exposure. Non-pharmacological care is the first-line treatment for substance withdrawal in newborns. Despite the widespread use of non-pharmacological care to mitigate symptoms of NAS, there is not an established definition of, and standard for, non-pharmacological care practices in this population. Evaluation of safety and efficacy of non-pharmacological practices could provide clear guidance for clinical practice.

OBJECTIVES

To evaluate the safety and efficacy of non-pharmacological treatment of infants at risk for, or having symptoms consistent with, opioid withdrawal on the length of hospitalization and use of pharmacological treatment for symptom management. Comparison 1: in infants at risk for, or having early symptoms consistent with, opioid withdrawal, does non-pharmacological treatment reduce the length of hospitalization and use of pharmacological treatment? Comparison 2: in infants receiving pharmacological treatment for symptoms consistent with opioid withdrawal, does concurrent non-pharmacological treatment reduce duration of pharmacological treatment, maximum and cumulative doses of opioid medication, and length of hospitalization?

SEARCH METHODS

We used the standard search strategy of Cochrane Neonatal to search CENTRAL (2019, Issue 10); Ovid MEDLINE; and CINAHL on 11 October 2019. We also searched clinical trials databases and the reference lists of retrieved articles for randomized controlled trials (RCTs), quasi-RCTs, and cluster trials.

SELECTION CRITERIA

We included trials comparing single or bundled non-pharmacological interventions to no non-pharmacological treatment or different single or bundled non-pharmacological interventions. We assessed non-pharmacological interventions independently and in combination based on sufficient similarity in population, intervention, and comparison groups studied. We categorized non-pharmacological interventions as: modifying environmental stimulation, feeding practices, and support of the mother-infant dyad. We presented non-randomized studies identified in the search process narratively.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the certainty of evidence. Primary outcomes in infants at risk for, or having early symptoms consistent with, opioid withdrawal included length of hospitalization and pharmacological treatment with one or more doses of opioid or sedative medication. Primary outcomes in infants receiving opioid treatment for symptoms consistent with opioid withdrawal included length of hospitalization, length of pharmacological treatment with opioid or sedative medication, and maximum and cumulative doses of opioid medication.

MAIN RESULTS

We identified six RCTs (353 infants) in which infants at risk for, or having symptoms consistent with, opioid withdrawal participated between 1975 and 2018. We identified no RCTs in which infants receiving opioid treatment for symptoms consistent with opioid withdrawal participated. The certainty of evidence for all outcomes was very low to low. We also identified and excluded 34 non-randomized studies published between 2005 and 2018, including 29 in which infants at risk for, or having symptoms consistent with, opioid withdrawal participated and five in which infants receiving opioid treatment for symptoms consistent with opioid withdrawal participated. We identified seven preregistered interventional clinical trials that may qualify for inclusion at review update when complete. Of the six RCTs, four studies assessed modifying environmental stimulation in the form of a mechanical rocking bed, prone positioning, non-oscillating waterbed, or a low-stimulation nursery; one study assessed feeding practices (comparing 24 kcal/oz to 20 kcal/oz formula); and one study assessed support of the maternal-infant dyad (tailored breastfeeding support). There was no evidence of a difference in length of hospitalization in the one study that assessed modifying environmental stimulation (mean difference [MD) -1 day, 95% confidence interval [CI) -2.82 to 0.82; 30 infants; very low-certainty evidence) and the one study of support of the maternal-infant dyad (MD -8.9 days, 95% CI -19.84 to 2.04; 14 infants; very low-certainty evidence). No studies of feeding practices evaluated the length of hospitalization. There was no evidence of a difference in use of pharmacological treatment in three studies of modifying environmental stimulation (typical risk ratio [RR) 1.00, 95% CI 0.86 to 1.16; 92 infants; low-certainty evidence), one study of feeding practices (RR 0.92, 95% CI 0.63 to 1.33; 49 infants; very low-certainty evidence), and one study of support of the maternal-infant dyad (RR 0.50, 95% CI 0.13 to 1.90; 14 infants; very low-certainty evidence). Reported secondary outcomes included neonatal intensive care unit (NICU) admission, days to regain birth weight, and weight nadir. One study of support of the maternal-infant dyad reported NICU admission (RR 0.50, 95% CI 0.13 to 1.90; 14 infants; very low-certainty evidence). One study of feeding practices reported days to regain birth weight (MD 1.10 days, 95% CI 2.76 to 0.56; 46 infants; very low-certainty evidence). One study that assessed modifying environmental stimulation reported weight nadir (MD -0.28, 95% CI -1.15 to 0.59; 194 infants; very low-certainty evidence) and one study of feeding practices reported weight nadir (MD -0.8, 95% CI -2.24 to 0.64; 46 infants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

We are uncertain whether non-pharmacological care for opioid withdrawal in newborns affects important clinical outcomes including length of hospitalization and use of pharmacological treatment based on the six included studies. The outcomes identified for this review were of very low- to low-certainty evidence. Combined analysis was limited by heterogeneity in study design and intervention definitions as well as the number of studies. Many prespecified outcomes were not reported. Although caregivers are encouraged by experts to optimize non-pharmacological care for opioid withdrawal in newborns prior to initiating pharmacological care, we do not have sufficient evidence to inform specific clinical practices. Larger well-designed studies are needed to determine the effect of non-pharmacological care for opioid withdrawal in newborns.

Auricular acupressure and acupuncture as adjuncts for pain management during first trimester medication abortion: A randomized three-arm trial

OBJECTIVES

To measure pain during first trimester medication abortion using auricular acupressure or auricular acupuncture as an adjunct to pain management. We measured anxiety as a secondary outcome.

STUDY DESIGN

This randomized, double-blinded, 3-arm trial enrolled women seeking medication abortion with mifepristone and misoprostol. Participants received auricular acupressure, auricular acupuncture, or inert auricular placebo patches immediately after receiving mifepristone. In addition, all participants received ibuprofen to use at home as needed. The study started with 1:1:1 randomization, but later overenrolled into the acupressure group after retraining for greater fidelity to that intervention. Participants reported pain and anxiety using numeric rating scales via text message for 4 days, and using a visual analog scale at follow-up. Analyses compared median pain scores of those receiving acupressure, acupuncture, or placebo.

RESULTS

We randomized 136 participants of whom 57 received acupressure, 40 received acupuncture, and 39 received placebo. Groups had similar baseline characteristics. One hundred thirty-two participants (97%) reported outcomes by text message and 120 (88%) completed a follow-up interview. For acupressure, acupuncture and placebo groups the median maximum pain scores reported via text message were 60.0, 75.0, and 55.0 (p = 0.38); median maximum pain scores reported at follow-up were 76.5, 60.0, and 71.0 (p = 0.97), respectively. Acupressure results were similar before and after retraining. Maximum anxiety scores reported via text message were 10.0, 45.0, and 30.0 (p = 0.57). Maximum anxiety scores reported at follow-up were 10.5, 20.0, and 13.0 (p = 0.59).

CONCLUSIONS

Pain and anxiety during medication abortion were similar among women receiving acupressure, acupuncture or placebo.

IMPLICATIONS

We found no benefit in administering auricular acupressure or auricular acupuncture during medication abortion. These modalities are intended to be simple to use, but perhaps the brief provider training for this study was insufficient. These modalities should not be used in clinical practice without further study.

Feasibility of auricular acupressure as an adjunct treatment for neonatal opioid withdrawal syndrome (NOWS)

BACKGROUND

The opioid epidemic in the United States continues to threaten public health. As a result of this crisis, neonatal opioid withdrawal syndrome (NOWS) has risen exponentially and requires a multitude of non-pharmacologic treatments to ensure healthy neonatal outcomes. Methods: This feasibility study implemented an acupressure protocol as informed by the Near-Term Infant (NTI) conceptual framework for the treatment of NOWS. Aims of this study were to assess provider training, effective integration of acupressure within the standard of care, and acceptance of this treatment by mothers and healthcare providers. Results: With maternal consent, a total of 12 participants were enrolled and underwent auricular acupressure. Nurse Practitioners were credentialed (75%) and effectively administered neonatal acupressure (100%) in accordance with the study protocol. Mothers were very satisfied with acupressure for the treatment of NOWS (Client Satisfaction Questionaire-8 mean scores 3.8-4.0 of a possible 4.0), and the majority of healthcare providers were supportive (66%, mean scores 3.6 to 4.0 out of possible 5). Conclusions: Auricular acupressure was successfully implemented within the standard of care for NOWS. Future studies should incorporate outlined suggestions and include qualitative measures of acceptance as well as randomized controlled trials to evaluate efficacy.

Magnetic Non-invasive Auricular Acupuncture During Eye-Exam for Retinopathy of Prematurity in Preterm Infants: A Multicentre Randomized Controlled Trial

Background: Eye exam for Retinopathy of prematurity (ROP) is a painful procedure and pharmacological analgesia might be ineffective. We hypothesized that magnetic auricular acupuncture (MAA) compared to placebo will decrease pain during ROP exam in preterm infants. Methods: Multicentre randomized controlled trial conducted in three hospitals (Australia, Canada, and Malaysia). Eligibility: >32 weeks, ROP exam, not sedated, and parental consent. A total of 100 infants were randomized (1:1) to MAA (n = 50) or placebo (n = 50). MAA stickers or placebo were placed on both ears by an unblinded investigator. Pain was assessed using the Premature Infant Pain Profile. Primary analyses were by intention-to-treat. ClinicalTrials.gov:NCT03650621. Findings: The mean (standard deviation, SD) gestation, birthweight, and postnatal age were (MAA 28(3) vs. placebo 28(2) weeks; MAA 1,057(455) vs. placebo 952(273) g; MAA 7(3) vs. placebo 7(3) weeks. Placebo infants had significantly higher PIPP scores during [mean difference 1.6 points (95%CI 0.1-3.1)] and 1 h mean difference 1.5 points (95%CI 0.7-2.2) after the procedure (p < 0.03). Heart rate was lower (173(22) vs. 184(18)/min) and oxygen saturations were higher (93.8(6.2) vs. 91.7(6.1)%, p = 0.05) in MAA infants. No adverse effects. Interpretation: MAA may reduce physiological pain responses during and after ROP exam in preterm infants. Assessment of long-term effects are warranted. Clinical trial registration: www.ClinicalTrials.gov, identifier: NCT03650621.

Culturally Based Practice in Neonatal Procedural Pain Management: A Mini Review

Cultural factors have gradually become important considerations in health services, including in pain management for adult and pediatric patients. However, research on culturally based pain management in neonates remains limited. This mini review aims to provide an overview of procedural pain management in neonates based on cultural approaches from various countries. The review found that there are several analyses of pain management procedures for neonates developed from cultural practices, namely, acupuncture, foot massage and reflexology, Yakson touch therapy, and aromatherapy. The acupuncture method (invasive and non-invasive) is more widely studied using randomized controlled trials (RCTs) than the other methods because the techniques applied can be standardized and measured. There are indications of the positive impact of all the methods examined in this review, but the results of studies have not been consistent because of the diversity of outcome measurement methods used and because of the difficulty of creating standardized procedures to measure pain management methods that are based on cultural practices.

Acupuncture for pediatric pain: The trend of evidence-based research

Background and aim

Acupuncture is part of thousand years Traditional Chinese Medicine. There was promising evidence to support the efficacy of acupuncture in reducing postoperative surgery and dental pain, as well as chemotherapy-related nausea and vomiting. The US National Health Statistics Report indicated that there was significant increase in the use of acupuncture. Research on acupuncture has allowed for its integration into common adult pain practice. Acupuncture can also be utilized in pediatric patients.

Experimental procedure

We evaluate the evidence-based acupuncture for pediatric pain research from 2008 to 2017.

Results

and Conclusions: Acupuncture treatment is well supported to be effective treatment for pediatric procedural pain, infantile colic, adolescent pelvic pain, and headaches under specific intervention methods. There is increasing interest in using acupuncture and related techniques for pediatric pain management. However, the evidence-based randomized controlled trials using acupuncture for pediatric pain management is very limited. Further randomized controlled trial research in pediatric pain is urgently needed.

Neonatal Abstinence Syndrome: An Integrative Review of Neonatal Acupuncture to Inform a Protocol for Adjunctive Treatment

BACKGROUND

The current opioid epidemic in the United States has given rise to a growing incidence of neonatal abstinence syndrome (NAS). Treatments for this condition optimize nonpharmacologic therapies in an effort to improve withdrawal symptoms and reduce or eliminate the need for opioid medications, thereby reducing hospital length of stay and improving healthy neonatal outcomes.

PURPOSE

The purpose of this review was to evaluate the current evidence for neonatal acupuncture treatments and identify essential characteristics that must be included in a treatment protocol for NAS.

METHODS/SEARCH STRATEGY

An integrative review was conducted under the guidance of the Whittemore and Knafl methodology and near-term infant conceptual framework. An evaluation of the quality and levels of evidence was also included.

FINDINGS/RESULTS

A total of 10 studies were identified in this review. Four of these studies were randomized controlled trials, and utilized acupuncture in the neonatal population to evaluate impact on pain, NAS, and weight gain.

IMPLICATIONS FOR PRACTICE

This review provided the essential elements for the development of a complementary acupuncture treatment protocol for the management of NAS.

IMPLICATIONS FOR RESEARCH

Future research should include the identified essential characteristics in high-quality, blinded, randomized controlled trials to assess the treatment effect of acupuncture on neonates experiencing withdrawal symptoms.

A Scoping Review of Acupuncture as a Potential Intervention for Neonatal Abstinence Syndrome

Objective: Neonatal abstinence syndrome (NAS) has risen drastically over the past decade. Infants with NAS experience extreme discomfort and developmental delays when going into withdrawal. Management includes multiple supportive and nonpharmacologic therapies as first-line treatments in an effort to reduce or prevent the need for medication management. Acupuncture has demonstrated efficacy in adults experiencing withdrawal from addictions, as well as for treating many other conditions in pediatric patients who have similar symptoms to withdrawal. The purpose of this review is to evaluate the safety and efficacy of acupuncture for neonates in withdrawal. Materials and Methods: This review was guided by the Arksey and O'Malley methodological framework, and analysis was performed based on a social ecological model. The PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-Analyses] statement was used to organize selected publications, and a flow chart was created to display the search process. PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Databases were searched for relevant publications. Results: Acupuncture appears to be safe and effective for reducing withdrawal symptoms in infants, and, thus, should be considered as an additional nonpharmacologic treatment option for NAS.

A Review of Non-Pharmacological Treatments for Pain Management in Newborn Infants

Pain is a major problem in sick newborn infants, especially for those needing intensive care. Pharmacological pain relief is the most commonly used, but might be ineffective and has side effects, including long-term neurodevelopmental sequelae. The effectiveness and safety of alternative analgesic methods are ambiguous. The objective was to review the effectiveness and safety of non-pharmacological methods of pain relief in newborn infants and to identify those that are the most effective. PubMed and Google Scholar were searched using the terms: “infant”, “premature”, “pain”, “acupuncture”, “skin-to-skin contact”, “sucrose”, “massage”, “musical therapy” and ‘breastfeeding’. We included 24 studies assessing different methods of non-pharmacological analgesic techniques. Most resulted in some degree of analgesia but many were ineffective and some were even detrimental. Sucrose, for example, was often ineffective but was more effective than music therapy, massage, breast milk (for extremely premature infants) or non-invasive electrical stimulation acupuncture. There were also conflicting results for acupuncture, skin-to-skin care and musical therapy. Most non-pharmacological methods of analgesia provide a modicum of relief for preterm infants, but none are completely effective and there is no clearly superior method. Study is also required to assess potential long-term consequences of any of these methods.

Auricular Medicine in Neonatal Care

This article explores the possibilities of applying ear acupuncture to newborn infants. In addition to the use of needle acupuncture, there are also noninvasive applications that are preferred for patients in this particular age group. Based on the limited literature, ear acupuncture could be an effective nonpharmacologic approach for the treatment of pain in newborn infants and for addressing symptoms of neonatal abstinence syndrome. However, studies on safety, side-effects, and other indications are still lacking.
