Abstract
BACKGROUND Preterm infants (born before 37 weeks' gestation) are often unable to co-ordinate sucking, swallowing, and breathing for oral feeding because of their immaturity. In such cases, initial nutrition is provided by orogastric or nasogastric tube feeding. Feeding intolerance is common and can delay attainment of full enteral and sucking feeds, prolonging the need for nutritional support and the hospital stay. Smell and taste play an important role in the activation of physiological pre-absorptive processes that contribute to food digestion and absorption. However, during tube feeding, milk bypasses the nasal and oral cavities, limiting exposure to the smell and taste of milk. Provision of the smell and taste of milk with tube feeds offers a non-invasive and low-cost intervention that, if effective in accelerating the transition to enteral feeds and subsequently to sucking feeds, would bring considerable advantages to infants, their families, and healthcare systems. OBJECTIVES To assess whether exposure to the smell or taste (or both) of breastmilk or formula administered with tube feeds can accelerate the transition to full sucking feeds without adverse effects in preterm infants. SEARCH METHODS We conducted searches in CENTRAL, MEDLINE, Embase, CINAHL, and Epistemonikos to 26 April 2023. We also searched clinical trial databases and conference proceedings. SELECTION CRITERIA We included randomised and quasi-randomised studies that evaluated exposure versus no exposure to the smell or taste of milk (or both) immediately before or at the time of tube feeds. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias, and extracted data according to Cochrane Neonatal methodology. We performed meta-analyses using risk ratios (RRs) for dichotomous data and mean differences (MDs) for continuous data, with their respective 95% confidence intervals (CIs). We used GRADE to assess the certainty of evidence. MAIN RESULTS We included eight studies (1277 preterm infants). Seven studies (1244 infants) contributed data for meta-analysis. The evidence suggests that exposure to the smell and taste of milk with tube feeds has little to no effect on time taken to reach full sucking feeds (MD -1.07 days, 95% CI -2.63 to 0.50; 3 studies, 662 infants; very low-certainty evidence). Two studies reported no adverse effects related to the intervention. The intervention may have little to no effect on duration of parenteral nutrition (MD 0.23 days, 95% CI -0.24 to 0.71; 3 studies, 977 infants; low-certainty evidence), time to reach full enteral feeds (MD -0.16 days, 95% CI -0.45 to 0.12; 1 study, 736 infants; very low-certainty evidence) or risk of necrotising enterocolitis (RR 0.93, 95% CI 0.47 to 1.84; 2 studies, 435 infants; low-certainty evidence), although the evidence for time to reach full enteral feeds is very uncertain. Exposure to the smell and taste of milk with tube feeds probably has little to no effect on risk of late infection (RR 1.14, 95% CI 0.74 to 1.75; 2 studies, 436 infants; moderate-certainty evidence). There were no data available to assess feeding intolerance. The included studies had small sample sizes and methodological limitations, including unclear or lack of randomisation (four studies), lack of blinding of participants and personnel (five studies), unclear or lack of blinding of the outcome assessor (all eight studies), and different inclusion criteria and methods of administering the interventions. AUTHORS' CONCLUSIONS The results of our meta-analyses suggest that exposure to the smell and taste of milk with tube feeds may have little to no effect on time to reach full sucking feeds and time to reach full enteral feeds. We found no clear difference between exposure and no exposure to the smell or taste of milk on safety outcomes (adverse effects, necrotising enterocolitis, and late infection). Results from one ongoing study and two studies awaiting classification may alter the conclusions of this review. Future research should examine the effect of exposing preterm infants to the smell and taste of milk with tube feeds on health outcomes during hospitalisation, such as attainment of feeding skills, safety, feed tolerance, infection, and growth. Future studies should be powered to detect the effect of the intervention in infants of different gestational ages and on each sex separately. It is also important to determine the optimal method, frequency, and duration of exposure.

Qin Y, Liu S, Yang Y, Zhong Y, Hao D, Han H. Effects of human milk odor stimulation on feeding in premature infants: a systematic review and meta-analysis. Sci Rep 2024; 14:8964. [PMID: 38637563 PMCID: PMC11026474 DOI: 10.1038/s41598-024-59175-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Accepted: 04/08/2024] [Indexed: 04/20/2024] Open
Abstract
Previous studies suggested odor stimulation may influence feeding of premature neonates. Therefore, this systematic review and meta-analysis of randomized controlled trials was conducted to assess the effect of human milk odor stimulation on feeding of premature infants. All randomized controlled trials related to human milk odor stimulation on feeding in premature infants published in PubMed, Cochrane, Library, Medline, Embase, Web of science databases and Chinese biomedical literature databases, China National Knowledge Infrastructure, China Science and Technology Journal Database (VIP) and Wanfang Chinese databases were searched, and The Cochrane Handbook 5.1.0 was used to evaluate the quality and authenticity of the literature. Relevant information of the included studies was extracted and summarized, and the evaluation indexes were analyzed using ReviewManager5.3. The retrieval time was from the establishment of the database to July 28, 2022.12 articles were assessed for eligibility, and six randomized controlled studies were eventually included in the meta-analysis (PRISMA). A total of 6 randomized controlled studies with 763 patients were finally included in the study, and the quality evaluation of literatures were all grade B. Human milk odor stimulation reduced the transition time to oral feeding in premature infants [SMD = - 0.48, 95% CI (- 0.69, - 0.27), Z = 4.54, P < 0.00001] and shortened the duration of parenteral nutrition [MD = - 1.01, 95% CI (- 1.70, - 0.32), Z = 2.88, P = 0.004]. However, it did not change the length of hospitalization for premature infants [MD = - 0.03, 95% CI (- 0.41, 0.35), Z = 0.17, P = 0.86]. The implementation of human milk odor stimulation can reduce the transition time to oral feeding and the duration of parenteral nutrition in premature infants, but further studies are needed to determine whether it can reduce the length of hospital stay in premature infants. More high-quality, large-sample studies are needed to investigate the effect of human milk odor stimulation on the feeding process and other outcomes in premature infants.

Abstract
Human milk odor is attractive and appetitive for human newborns. Here, we studied behavioral and heart-rate (HR) responses of 2-day-old neonates to the odor of human colostrum. To evaluate detection in two conditions of stimulus delivery, we first presented the odor of total colostrum against water. Second, the hedonic specificity of total colostrum odor was tested against vanilla odor. Third, we delivered only the fresh effluvium of colostrum separated from the colostrum matrix; the stability of this colostrum effluvium was then tested after deep congelation; finally, after sorptive extraction of fresh colostrum headspace, we assessed the activity of colostrum volatiles eluting from the gas chromatograph (GC). Regardless of the stimulus-delivery method, neonates displayed attraction reactions (HR decrease) as well as appetitive oral responses to the odor of total colostrum but not to vanilla odor. The effluvium separated from the fresh colostrum matrix remained appetitive but appeared labile under deep freezing. Finally, volatiles from fresh colostrum effluvium remained behaviorally active after GC elution, although at lower magnitude. In sum, fresh colostrum effluvium and its eluate elicited a consistent increase in newborns' oral activity (relative to water or vanilla), and they induced shallow HR decrease. Newborns' appetitive oral behavior was the most reproducible response criterion to the effluvium of colostrum. In conclusion, a set of unidentified volatile compounds from human colostrum is robust enough after extraction from the original matrix and chromatographic processing to continue eliciting appetitive responses in neonates, thus opening new directions to isolate and assay specific volatile molecules of colostrum.

Abstract
Objective: The study aimed to determine the effect of the breast milk odor on the pain and stress levels of the newborn during the endotracheal suction procedure. Method: The study was conducted in the randomized-controlled experimental design at the neonatal intensive care unit of the hospital in eastern Turkey between March 2022 and December 2023. The study population included newborns at the 37th to 41st gestational weeks who were receiving mechanical ventilation treatment in the neonatal intensive care unit of a hospital in eastern Turkey. All newborns who met the inclusion criteria during the data collection phase were included in the study. The study was completed with 88 newborns (44 in the intervention group and 44 in the control group). The Newborn Introductory Information Form, ALPS-Neo Newborn Pain and Stress Assessment Scale, and follow-up form were used to collect the study data. The breast milk odor of the mothers of the newborns was used as the intervention group in the study. The mothers of the newborns were contacted to obtain breast milk, and the information was obtained from the mother on the day of the procedure. One milliliter of breast milk was taken and dropped into a sterile sponge, and it was held 10 cm away from the baby's nose from 5 minutes before to 5 minutes after endotracheal suction. A routine endotracheal suction process was performed in the control group. Ethical principles were followed in the study. Results: We found that the intervention group's pain and stress score averages were lower than the control group during and after the endotracheal suction procedure (p < 0.05). Conclusion: We found that the breast milk odor reduced the pain, stress levels, and crying duration of newborns during the endotracheal suction process.

Explore (NY) 2024; 20:206-211.

Abstract
INTRODUCTION AND OBJECTIVES Since preterm infants frequently undergo painful diagnostic and therapeutic procedures, pain management, especially through non-pharmacological methods, will be extremely beneficial. Accordingly, the present study aimed to compare the effects of aromatherapy with breast milk, Lavandula stoechas, and Rosa damascena on venipuncture pain in preterm infants. METHODS In this interventional study, preterm infants were randomly divided into four groups of aromatherapy with breast milk (25 infants), Lavandula stoechas (25 infants), Rosa damascena (25 infants), and sham (25 infants). One minute before, during, and two minutes after venipuncture, the Neonatal Infant Pain Scale (NIPS) as well as heart rate and SPO2 were measured. RESULTS The results indicated that pain intensity was significantly lower during and after venipuncture in all the aromatherapy methods compared with the sham group (P < 0.001). Breast milk odor decreased the pain more than the other two odors during and after venipuncture (P < 0.001); however, there was no significant difference between Lavandula stoechas and Rosa damascena (P = 0.94). SPO2 was significantly higher in infants in the Lavandula stoechas (P < 0.001) and Rosa damascena (P = 0.03) groups compared with the sham infants. CONCLUSION All three aromatherapy methods were effective in decreasing preterm infants' venipuncture pain. Since no study on the effect of aromatherapy with Rosa damascena was found in this regard, the effectiveness of aromatherapy with Rosa damascena is of great importance, and future studies are recommended to analyze this topic in greater depth.

Abstract
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.

Abstract
Research on human milk has increased dramatically in recent years. The purpose of this review is to describe the literature on the health benefits of human milk for hospitalized, vulnerable neonates. PubMed, CINAHL, and Embase were searched for research articles reporting the health outcomes of hospitalized neonates who were exposed to human milk. Human milk, particularly a mother's own milk, has the potential to reduce the risk of death and the risk and severity of necrotizing enterocolitis, infection, retinopathy of prematurity, bronchopulmonary dysplasia, intraventricular hemorrhage, kidney disease, and liver disease. Dose and timing of human milk is important, with more human milk and earlier introduction having a greater impact on health. When a mother's own milk is not available, donor human milk provides benefits over infant formula.

Abstract
Purpose: This study aimed to evaluate the effect of breast milk olfactory stimulation on pain response in premature infants during heel stick tests. Methods: A quasi-experimental randomized controlled trial was conducted in the neonatal intensive care unit of a tertiary-level hospital in Seoul, Korea. A breast milk group was provided olfactory stimulation with breast milk 30 seconds before the start of heel stick sampling, and a control group underwent heel stick sampling without olfactory stimulation. To evaluate infants' pain response, the heel stick procedure was video recorded, and pain response was assessed separately by two blinded research assistants using the Premature Infant Pain Scale (PIPS) through behavioral response, heart rate on physiological monitoring, and blood oxygen saturation on pulse oximetry through the video recording. Results: Forty-eight premature infants (gestational age, within 28-37 weeks, n = 24; control) were included in this study. The pain scores of the breast milk group were significantly lower than those of the control group (z = -2.04, p = 0.021). Conclusion: Breast milk odor may reduce pain in premature infants during heel stick tests.

[PMID: 35162263 PMCID: PMC8834920 DOI: 10.3390/ijerph19031240] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Revised: 01/18/2022] [Accepted: 01/19/2022] [Indexed: 01/27/2023]
Abstract
This study aimed to evaluate the efficacy of breast milk odor either alone or in combination with breast milk taste (via syringe-feeding) to alleviate neonates’ biobehavioral responses to pain during heel-prick procedures. This prospective randomized controlled trial recruited 114 neonates by convenience sampling from a newborn unit of a medical center in Taiwan. Neonates were randomly assigned to three groups: control (gentle touch + human voice), control + breast milk odor, and control + breast milk odor + breast milk taste. Heart rate, oxygen saturation, and voice recordings of crying were measured across heel-prick procedures: baseline, no stimuli (stage 0); during heel prick (Stages 1–4); and recovery (Stages 5–10). Generalized estimating equations and Kaplan–Meier survival analysis compared differences in changes between groups for heart rate, oxygen saturation, and time to crying cessation. Changes in mean heart rate and oxygen saturation in neonates receiving breast milk odor or breast milk odor + breast milk taste were significantly less than those at the corresponding stage for the control group. Among neonates receiving breast milk odor or breast milk odor + breast milk taste, hazard rate ratios for crying cessation were 3.016 and 6.466, respectively. Mother’s breast milk olfactory and gustatory interventions could stabilize the biobehavioral responses to pain during heel prick procedures in neonates.

Comparison of the analgesic effect of inhaled lavender vs vanilla essential oil for neonatal frenotomy: a randomized clinical trial (NCT04867824). Eur J Pediatr 2022; 181:3923-3929. [PMID: 36076107 PMCID: PMC9458311 DOI: 10.1007/s00431-022-04608-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 08/24/2022] [Accepted: 09/01/2022] [Indexed: 11/25/2022]
Abstract
UNLABELLED It is necessary to treat neonatal pain because it may have short- and long-term adverse effects. Frenotomy is a painful procedure where sucking, a common strategy to relieve pain, cannot be used because the technique is performed on the tongue. In a previous randomized clinical trial, we demonstrated that inhaled lavender essential oil (LEO) reduced the signs of pain during neonatal frenotomy. We aimed to find out whether inhaled vanilla essential oil (VEO) is more effective in reducing pain during frenotomy than LEO. Randomized clinical trial with neonates who underwent a frenotomy for type 3 tongue-ties between May and October 2021. Pain was assessed using pre and post-procedure heart rate (HR) and oxygen saturation (SatO2), crying time, and NIPS score. Neonates were randomized into "experimental" and "control" group. In both groups, we performed swaddling, administered oral sucrose, and let the newborn suck for 2 min. We placed a gauze pad with one drop of LEO (control group) or of VEO (experimental group) under the neonate's nose for 2 min prior to and during the frenotomy. We enrolled 142 neonates (71 per group). Both groups showed similar NIPS scores (2.02 vs 2.38) and crying times (15.3 vs 18.7 s). We observed no differences in HR increase or in SatO2 decrease between both groups. We observed no side effects in either of the groups. CONCLUSIONS We observed no appreciable difference between LEO and VEO; therefore, we cannot conclude which of them was more effective in treating pain in neonates who underwent a frenotomy. TRIAL REGISTRATION This clinical trial is registered with www. CLINICALTRIALS gov with NCT04867824. WHAT IS KNOWN • Pain management is one of the most important goals of neonatal care as it can have long-term neurodevelopmental effects. • Lavender essential oil can help relieve pain due to its sedative, antispasmodic, and anticolic properties. WHAT IS NEW • Lavender and vanilla essential oils are safe, beneficial, easy to use, and cheap in relieving pain in neonates who undergo a frenotomy for type 3 tongue-ties.

Abstract
PURPOSE Invasive intervention can negatively affect prognosis, behavior, environmental adaptation in neonates. Some nonpharmacological pain management methods are used for effective pain treatment. This study investigated the effect of breastfeeding, kangaroo care, and facilitated tucking positioning on heel-stick pain in neonates. DESIGN A quasi-experimental design was employed. The study was conducted in three family health centers in Kütahya/Turkey. The sample consisted of 140 healthy neonates with the gestational age of 37 weeks or more, birth weight greater than 2500 g, and no sucking problems. The sample was divided into four groups (breastfeeding, kangaroo care, facilitated tucking position, and control). Data were collected using a Baby-Mother Characteristics Questionnaire, a Physiological Parameter Follow-up Form, and the Neonatal Infant Pain Scale. Data were analyzed using chi-square, the one-way analysis of variance (ANOVA), Kruskal-Wallis, Student t-test, and Mann-Whitney U tests. The research adhered to ethical principles. RESULTS The facilitated tucking position group cried less and experienced less pain during heel stick than the other groups (p < 0.05). Breastfeeding, kangaroo care, and facilitating tucking help reduce heel-stick pain but facilitating tucking causes less crying and imposes less pain on neonates than the other methods. CONCLUSION Facilitated tucking position may be preferred to reduce pain during heel stick. PRACTICE IMPLICATIONS Using facilitated tucking positions and breastfeeding methods can assist healthcare professionals as supportive methods in pain management.

Abstract
Objective: Our research was conducted empirically to determine whether another mother's breast milk could be used to reduce the pain of newborns who were not able to access their own mother's milk for any reason. Materials and Methods: The sample group of the research included 90 newborns [smell of own mother's milk (30), smell of another mother's milk (30), and the control group (30)] hospitalized in the unit. A neonatal information form was used as the data collection tool, the Neonatal Pain, Agitation, and Sedation Scale (N-PASS) was used to assess the newborn's pain, and an evaluation form prepared by the researcher was used to record the findings. Results: The group which was exposed to their own mother's milk had a significantly lower N-PASS mean score compared to other groups and the group which was exposed to another mother's milk was observed to have a significantly lower N-PASS mean score compared to the control group (p < 0.05). While the median values for the total time spent crying of the "own mother's milk" group and the "another mother's milk" group were similar; the total time spent crying of the control group had a significantly higher median value. Conclusion: Our research determined that, while the most effective method for reducing pain in newborns was the smell of their own mother's breast milk, for newborns who were not able to access their own mother's breast milk, the smell of breast milk from a different mother could also be used.

The Effects of a Continuous Olfactory Stimulation Using Breast Milk (COSB) on Behavioral State and Physiological Responses in Korean Premature Infants. J Pediatr Nurs 2020; 53:e114-e120. [PMID: 32147276 DOI: 10.1016/j.pedn.2020.02.042] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 02/25/2020] [Accepted: 02/25/2020] [Indexed: 11/23/2022]
Abstract
PURPOSE This study aimed to evaluate the effects of continuous olfactory stimulation with breast milk (COSB) on behavioral and physiologic states of Korean premature infants. DESIGN AND METHODS We examined the COSB effects on the behavioral states and physiological responses, including heart rate and oxygen saturation, in 30 premature infants using a non-equivalent control group pre- and post-test design. Sterile 2 cm × 2 cm gauzes wet with 2 cc breast milk were placed 10 cm away from the infants' nostrils 8 times per day for 3 consecutive days. We obtained five measurements each of the behavioral state, heart rate, and oxygen saturation of the premature infants in the neonatal intensive care unit (NICU). Statistical analysis was conducted using descriptive statistics and two-way repeated-measures ANOVA. RESULTS The experiment group presented significantly reduced heart rate variations (p = .039). There were significant differences in the heart rate at all time-points in the control group (p < .001) but not in the experimental group, indicating more stable (p > .089) heart rates in the latter group. There were positive COSB effects on the behavioral states of premature infants at some time points. CONCLUSIONS COSB can be a useful intervention program for high-risk infants for partial behavioral state stabilization and significant heart rate stabilization. PRACTICE IMPLICATIONS COSB might enable NICU nurses to provide a useful and safe developmental care plan for the premature infants hospitalized in the NICU to improve their physiologic and behavioral condition.

Abstract
BACKGROUND Preterm and full-term neonates undergo many painful procedures during their hospitalization in the neonatal intensive care unit. Unrelieved and repeated pain can have important repercussions on their motor and intellectual development. Still, pain management interventions are limited for neonates. OBJECTIVE This systematic review aimed to evaluate the effectiveness of olfactive stimulation interventions on the pain response of preterm and full-term infants during painful procedures. DESIGN Systematic review and meta-analysis. DATA SOURCES An electronic search was conducted from inception to August 2019 in PubMed, MEDLINE, Embase, CINAHL, PsycINFO, Web of Sciences, CENTRAL, Scopus and ProQuest. REVIEW METHODS Study selection, data extraction, assessment of risk of bias and quality of evidence were performed by two independent reviewers. RESULTS 3311 studies were screened. Of the 14 studies included studies (n = 1028 infants), results from 10 were combined in meta-analysis. The latter demonstrated that olfactive stimulation interventions using a familiar odor were effective compared to standard care on pain reactivity (SMD -0.69; 95% CI -0.93 to -0.44; I2 = 20%, p < 0.00001), pain regulation (SMD -0.40; 95% CI -0.66 to -0.14; I2 = 13%, p = 0.002), crying duration during (SMD -0.42; 95% CI -0.73 to -0.10; I2 = 47%, p = 0.009) and after the procedure (SMD -0.37; 95% CI -0.68 to -0.07; I2 = 0%, p = 0.01), heart rate after the procedure (MD -3.87; 95% CI -7.36 to -0.38; I2 = 99%, p = 0.03), oxygen saturation during (MD -0.47; 95% CI -0.86 to -0.08; I2 = 91%, p = 0.02) and after the procedure (MD -0.56; 95% CI -0.99 to -0.13; I2 = 99%, p = 0.01). No adverse event was reported. CONCLUSION These findings are based on low to very low quality of evidence limiting our confidence in effect estimates. More rigorous trials with a larger sample size are needed to enhance the comprehension of the mechanisms underlying olfactive stimulation interventions and the interventions' efficacy.

Abstract
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.

Abstract
PURPOSE To compare the effects of integrating mother's breast milk (BM) with three different combinations of sensory stimuli on preterm infant pain during peripheral venipuncture procedures. DESIGN A prospective, repeated-measures randomized controlled trial. METHODS Preterm infants (gestational age between 28 and 37 weeks, and in stable condition) needing venipuncture were recruited by convenience sampling (N = 140) and randomly assigned to four treatment conditions: (a) routine care (condition 1); (b) BM odor or taste (condition 2); (c) BM odor or taste + heartbeat sounds (HBs; condition 3), and (d) BM odor or taste + HBs + non-nutritive sucking (NNS; condition 4). Pain scores were assessed based on the Premature Infant Pain Profile-Revised (PIPP-R) over nine phases: baseline (phase 0, 5 min without stimuli before venipuncture), disinfecting (phase 1), during venipuncture (phase 2), and a 10-min recovery (phases 3-8). FINDINGS Infants who received BM odor or taste + HBs + NNS had significantly lower increases in pain scores from baseline compared with controls across phases 1 through 8. Infants treated with either condition 2 or 3 demonstrated significant reductions in mild pain during disinfecting and recovery phases, as compared with the controls. When condition 2 was used as the reference, there were no significant differences in pain scores between the infants receiving condition 3 across the nine phases, suggesting mothers' HBs have only mild analgesic effects on venipuncture pain. CONCLUSIONS Integration of mother's BM odor or taste, HBs, and tactile NNS should be considered as an intervention for alleviation of procedural pain for preterm infants. CLINICAL RELEVANCE Clinicians should incorporate the integrated sensory intervention into caregiving support for preterm infants undergoing short painful procedures.

Abstract
BACKGROUND Preterm infants are often unable to co-ordinate sucking, swallowing and breathing for oral feeding because of their immaturity; in such cases, initial nutrition is provided by orogastric or nasogastric tube feeding. Feed intolerance is common and can delay attainment of full enteral feeds and sucking feeds, which prolongs the need for intravenous nutrition and hospital stay. Smell and taste play an important role in the activation of physiological pre-absorptive processes that contribute to food digestion and absorption. However, during tube feedings, milk bypasses the nasal and oral cavities, which limits exposure to the smell and taste of milk. Provision of the smell and taste of milk with tube feedings is non-invasive and inexpensive; and if it does accelerate the transition to enteral feeds, and then to sucking feeds, it would be of considerable potential benefit to infants, their families, and the healthcare system. OBJECTIVES To assess whether exposure to the smell or taste (or both) of milk administered with tube feedings can accelerate progress to full sucking feeds without adverse effects in preterm infants. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2018, Issue 5), MEDLINE via PubMed (1966 to 1 June 2018), Embase (1980 to 1 June 2018), and CINAHL (1982 to 1 June 2018). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised and quasi-randomised trials. SELECTION CRITERIA We included randomised and quasi-randomised studies that compared the provision of the smell or taste of milk (or both) immediately before or at the time of tube feedings, with no provision of smell or taste. DATA COLLECTION AND ANALYSIS Two review authors independently abstracted data according to Cochrane Neonatal methodology; they also assessed risk of bias, and the quality of evidence at the outcome level using the GRADE approach. We performed meta-analyses using risk ratio (RR) for dichotomous data and mean difference (MD) for continuous data, with their respective 95% confidence intervals (CIs). MAIN RESULTS Three trials involving a total of 161 preterm infants were included in this review, but only two trials (131 infants) contributed data for meta-analysis. There was no evidence of a clear effect of exposure to the smell and taste of milk with tube feedings on time taken to reach full sucking feeds (MD -2.57 days, 95% CI -5.15 to 0.02; I2 = 17%; 2 trials, 131 infants; very low-quality evidence). One trial reported no adverse effects. There was no evidence of a clear effect of exposure to the smell and taste of milk on the following outcomes: time taken to reach full enteral feeds (MD -1.57 days, 95% CI -6.25 to 3.11; 1 trial, 51 infants; very low-quality evidence), duration of parenteral nutrition (MD -2.20 days, 95% CI -9.49 to 5.09; 1 trial, 51 infants; very low-quality evidence), incidence of necrotising enterocolitis (RR 0.62, 95% CI 0.15 to 2.48; 1 trial, 51 infants; low-quality evidence), and late infection (RR 2.46, 95% CI 0.27 to 22.13; 1 trial, 51 infants; low-quality evidence). There was very low-quality evidence demonstrating that exposure to the smell and taste of milk decreased duration of hospitalisation by almost four days (MD -3.89 days, 95% CI -7.03 to -0.75; I2 = 51%; 2 trials, 131 infants). In two trials, an increased growth velocity was noted in infants exposed to the intervention, but we were unable to combine data to perform meta-analysis. No data were available to assess feed intolerance and rates of exclusive breastfeeding at discharge. Included trials were small and had methodological limitations including lack of randomisation (one trial), lack of blinding, and different inclusion criteria and administration of the interventions. AUTHORS' CONCLUSIONS Evidence from two trials suggests that exposure to the smell and taste of milk with tube feedings has no clear effect on time taken to reach full sucking feeds, but it may decrease length of hospitalisation. However, these results are uncertain due to the very low quality of the evidence. There is also limited evidence about the impact on other important clinical outcomes and on safety. Future research should examine the effect of exposure to the smell and taste of milk with tube feedings on clinical outcomes during hospitalisation, such as attainment of full enteral and sucking feeds, safety, feed tolerance, incidence of infection, and infant growth. Additionally, future research should be sufficiently powered to evaluate the effect of the intervention in infants of different gestational ages, on each sex separately, and on the optimal frequency and duration of exposure.

Abstract
OBJECTIVE The objective of this study was to evaluate the analgesic effects of maternal milk odor on newborns. MATERIALS AND METHODS We searched the literature in PubMed, MEDLINE, CINAHL, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) and collected all the randomized controlled trials (RCTs) investigating the effects of maternal milk odor versus scentless or other odors on procedural pain in newborns. The quality of included studies was assessed by the Cochrane Collaboration Risk of Bias tool. A meta-analysis was undertaken with the Review Manager 5.3 software and Stata version 11.0. Subgroup comparisons were prespecified according to the types of control groups. RESULTS Eight RCTs included a total of 453 participants. The results of meta-analysis showed that compared with the scentless group, the maternal milk odor group had lower pain scores during blood sampling (standardized mean difference, -0.81; 95% confidence interval [95% CI], -1.18 to -0.44; p < 0.001) and shorter crying time afterward (mean difference, -8.10; 95% CI, -15.46 to 0.73; p = 0.03). The maternal milk odor group had lower heart rate variability and oxygen saturation variability during and after a procedure, compared with both the scentless group and the vanilla group. However, no significant difference was identified in the mean heart rate and mean oxygen saturation in terms of the maternal milk odor group compared with amniotic fluid odor or mother's scent. The maternal milk odor group versus the formula milk odor group had shorter crying duration and lower levels of salivary cortisol after sampling. CONCLUSIONS Maternal milk odor appears to play an analgesic role in newborns. However, more high-quality studies are needed to confirm and quantitate the effect.

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