Longer duration of kangaroo care improves neurobehavioral performance and feeding in preterm infants: a randomized controlled trial

A Staff Educational Intervention to Increase the Time of Skin-to-Skin Care in a Swedish NICU: A Quality Improvement Project

BACKGROUND

Skin-to-skin contact (SSC) is crucial in neonatal intensive care unit (NICU) care; yet, challenges exist in its implementation. This study addresses a knowledge gap by examining the most effective ways to introduce SSC in the NICU, emphasizing the need to seamlessly integrate this practice for optimal infant and parent care. One way, among many, to implement SSC is to increase staff's knowledge and awareness about SSC.

OBJECTIVE

To describe the effect of an educational intervention on SSC time, the number of SSC sessions per day, and the number of infants cared for with SSC within their first day of life.

METHODS

A pre- and postinterventional study design was used to determine the effect of an educational intervention on SSC time, the number of SSC sessions per day, and the number of infants cared for with SSC within their first day of life.

RESULTS

The prevalence of infants receiving SSC during their first 24 hours of life, the number of SSC sessions per day, and the duration of each SSC session increased after the intervention, and these effects persisted over 2 years.

IMPLICATIONS FOR PRACTICE

Our study highlights the impact of staff education and reflective discussions on SSC in the NICU. Integrating these with practical training, parental education, and NICU environment modifications is pivotal for enhancing and sustaining optimal SSC practices, benefiting both infants and parents.

Consensus document for the kangaroo mother care method

INTRODUCTION

Currently, kangaroo mother care (KMC) is an intervention whose implementation in clinical practice varies widely. The aim of this document is to gather the latest evidence-based recommendations in an attempt to reduce interprofessional variation and increase the quality of neonatal care.

METHODS

The document was developed following the guidelines provided in the Methodological Manual for the Development of Clinical Practice Guidelines of the National Health System: formulation and prioritization of clinical questions, literature search, critical reading, development of the document and external review. The target population was preterm (PT) and/or low birth weight (LBW) newborn infants admitted to a neonatal unit.

RECOMMENDATIONS

Based on the current evidence, recommendations have been issued to address 18 clinical questions regarding the impact of KMC (morbidity and mortality, physiological stability, neurodevelopment, feeding, pain, families), including infants with vascular access or respiratory support devices. It also describes the KMC procedure (transfer, positioning), the facilitators and barriers related to the implementation of KMC and how to implement KMC in extremely preterm newborns (less than 28 weeks of postmenstrual age in the first days of life).

CONCLUSIONS

Kangaroo mother care is a beneficial practice for PT infants, LBW infants and their families. The implementation of these recommendations may be useful in everyday clinical practice and may improve KMC outcomes and the quality of care provided to neonatal patients.

Complications of Preterm Birth-The Importance of Care for the Outcome: A Narrative Review

Preterm-born children are susceptible to problems of adaptation in the early neonatal period, as well as the emergence of consequences due to the immaturity of the respiratory, cardiovascular, and especially cerebrovascular systems. The authors searched PubMed, Scopus, the Cochrane Library, and Web of Science for articles that were available in their entirety and published in English between 1990 and 2024 in peer-reviewed journals using keywords relevant to the manuscript topic. Analyzing the requested studies and manuscripts, adequate articles describing the stated problem were used. The last trimester of pregnancy is the most important period in brain development. Brain growth is at its most intense, and nerve cells are created, multiply, and migrate, creating numerous connections between them and receptors. During this period, the baby is protected from the influence of external environmental factors. When a baby is born, it leaves its protected environment and very often requires intensive treatment to survive. In these circumstances, the immature nervous system, which is in a sensitive stage of development, is overloaded with numerous external stimuli, continuous light, noise, inappropriate positioning, and repeated painful reactions due to necessary diagnostic and therapeutic procedures and the unavoidable absence of the mother and the family, which cause stress that threatens proper programmed development. Minimally invasive therapeutic procedures and the presence of parents during hospitalization play a significant role in reducing the consequences for a premature child.

A systematic review and multivariate meta-analysis of the physical and mental health benefits of touch interventions

Receiving touch is of critical importance, as many studies have shown that touch promotes mental and physical well-being. We conducted a pre-registered (PROSPERO: CRD42022304281) systematic review and multilevel meta-analysis encompassing 137 studies in the meta-analysis and 75 additional studies in the systematic review (n = 12,966 individuals, search via Google Scholar, PubMed and Web of Science until 1 October 2022) to identify critical factors moderating touch intervention efficacy. Included studies always featured a touch versus no touch control intervention with diverse health outcomes as dependent variables. Risk of bias was assessed via small study, randomization, sequencing, performance and attrition bias. Touch interventions were especially effective in regulating cortisol levels (Hedges' g = 0.78, 95% confidence interval (CI) 0.24 to 1.31) and increasing weight (0.65, 95% CI 0.37 to 0.94) in newborns as well as in reducing pain (0.69, 95% CI 0.48 to 0.89), feelings of depression (0.59, 95% CI 0.40 to 0.78) and state (0.64, 95% CI 0.44 to 0.84) or trait anxiety (0.59, 95% CI 0.40 to 0.77) for adults. Comparing touch interventions involving objects or robots resulted in similar physical (0.56, 95% CI 0.24 to 0.88 versus 0.51, 95% CI 0.38 to 0.64) but lower mental health benefits (0.34, 95% CI 0.19 to 0.49 versus 0.58, 95% CI 0.43 to 0.73). Adult clinical cohorts profited more strongly in mental health domains compared with healthy individuals (0.63, 95% CI 0.46 to 0.80 versus 0.37, 95% CI 0.20 to 0.55). We found no difference in health benefits in adults when comparing touch applied by a familiar person or a health care professional (0.51, 95% CI 0.29 to 0.73 versus 0.50, 95% CI 0.38 to 0.61), but parental touch was more beneficial in newborns (0.69, 95% CI 0.50 to 0.88 versus 0.39, 95% CI 0.18 to 0.61). Small but significant small study bias and the impossibility to blind experimental conditions need to be considered. Leveraging factors that influence touch intervention efficacy will help maximize the benefits of future interventions and focus research in this field.

Systematic Review of Kangaroo Care Duration's Impact in Neonatal Intensive Care Units on Infant-Maternal Health

Kangaroo care (KC), skin-to-skin contact between infants and caregivers, is encouraged in neonatal intensive care units (NICUs) to support health through improved weight, growth, and infant-maternal attachment while reducing the incidence of sepsis and infant pain. However, the optimal duration and frequency of KC to maximize health outcomes is unknown. Given parents' time stressors, identifying optimal KC time is critical. A literature review was undertaken on May 28, 2021 via querying the PubMed database from January 1, 1995, to May 28, 2021, regarding KC and NICUs with 442 results. Eleven studies met the eligibility criteria of (1) comparative KC between infants and adult caregivers in NICUs as a randomized controlled trial, (2) peer-reviewed articles in English, (3) study subjects ≥5, (4) health outcomes, and (5) KC sessions >1. Infant physical growth parameters, infant neurodevelopment, infant stress via salivary cortisol levels, and breastfeeding outcomes appear to increase with KC as compared with standard care (SC) without KC. Improvements were observed with longer KC duration, 2 h/d as compared with 1 h/d, for neurodevelopment and breastfeeding outcomes, but no greater improvement with longer KC duration was shown for reducing infant stress through salivary cortisol levels. Regarding maternal stress, the influence of KC duration showed mixed Parental Stressor Score: NICU scores. Further study on the impact of KC duration and frequency on health outcomes and dose-response relationship would help determine how much and how frequent KC is needed to improve specific health outcomes for infants and their mothers. KEY POINTS: · Data on kangaroo care duration's health impacts is lacking.. · Establishing dose-response for kangaroo care is needed.. · Kangaroo care for longer improves some but not all outcomes..

Impact of Parent Presence and Engagement on Stress in NICU Infants

BACKGROUND

Infants in neonatal intensive care units (NICUs) are exposed to frequent stressors that impact their neurodevelopmental outcomes. Parent presence and engagement are considered critical to improving infant outcomes, yet associations between cumulative NICU parent presence, engagement, and infant stress are infrequently examined.

PURPOSE

To examine associations between NICU infant stress and the amount (hours per week) or frequency (days per week) of parent presence and skin-to-skin care (SSC).

METHODS

A secondary analysis of a data set representing 78 NICU families was conducted. Infant acuity was measured using Neonatal Medical Index (NMI) scores. Parent presence and SSC data were collected from electronic medical records. Infant stress was measured using resting salivary cortisol levels collected at NICU discharge (median = 33 days of life).

RESULTS

More cumulative SSC was associated with lower discharge cortisol in NICU infants for SSC measured in hours per week (P = .03) or days per week (P = .05). Cumulative parent presence was not significantly associated with infant cortisol at discharge. Hierarchical regression analyses examining timing of parent presence supported a model including admission cortisol, NMI score, and parent presence during weeks 1 to 4 of life for explaining infant stress at discharge (R2 = 0.44, P = .004). Analyses examining timing of SSC supported a model including admission cortisol, NMI score, and frequency of SSC during week 1 for explaining infant stress at discharge (R2 = 0.21, P = .04).

IMPLICATIONS FOR PRACTICE AND RESEARCH

Early, frequent SSC to mitigate stress in NICU infants was supported. Results suggested that timing of parent presence impacts NICU infant stress; however, additional study is recommended.

Predictors of time to full enteral feeding in low birth weight neonates admitted to neonatal intensive care unit: a prospective follow up study

BACKGROUND

Survival of LBW infants has increased in recent years because of novel perinatal interventions, but the introduction and advancement of enteral feeds for low birth weight infants is challenging. In Ethiopia the proportion of low birth weight infants is thought to be 17.3%. The purpose of this study was to determine the time to full enteral feeding (FEF) and its predictors in LBW neonates admitted to neonatal intensive care unit in selected hospitals of Addis Ababa, Ethiopia.

METHOD

An institutional based prospective follow up study was conducted from March 15 to June 15, 2022 among 282 LBW neonates admitted to six randomly selected hospitals. Both primary and secondary data was used by interviewing mothers and prospective medical chart review of neonates. The Cox regression model was used and variables having a p-value less than 0.05 with 95% CIs in a multivariable analysis were declared as statistically significant association with time to full enteral feeding.

RESULT

Out of 282 neonates involved in this study, 211 (74.8%) of them reached at FEF. The overall median time to full enteral feeding was 5 days. Predictors significantly associated with time to full enteral feeding were educational level, birth weight, cesarean delivery, hospital acquired infection, being on antibiotics, age at initiation of trophic feeding, routine gastric residual evaluation and NICU location (hospital).

CONCLUSIONS

This study demonstrated the difficulty of understanding which low birth weight neonate will attain FEF in a timely manner and factors that affect time to FEF. There is a delay in full enteral feeding achievement among low birth weight neonates and there is a great deal of heterogeneity of practice among health care providers regarding feeding of infants as it was evidenced by a variation in feeding practice among hospitals. Nutrition should be considered as part of the management in neonatal intensive care units since low birth weight neonates are developing edematous malnutrition while they are in the NICU. There should be standard feeding protocol to avoid heterogeneity of practice and additional study should be conducted for each categories of GA and BW with long follow up time.

The effect of the swaddling method on stress levels in newborns administered nasal CPAP

BACKGROUND

This study aims to investigate the effects of the swaddling method on the stress levels in newborns receiving nasal continuous positive airway pressure (nCPAP).

METHODS

The study was conducted between 1 June 2022 and 1 October 2022 with 40 newborns who underwent nCPAP in the second-level Neonatal Intensive Care Unit (NICU) of a city hospital in the Central Anatolia Region of Turkey. Data were collected using a descriptive form, including the characteristics of newborns, a patient follow-up chart, and the Newborn Stress Scale (NSS). The descriptive form, the patient follow-up chart, and the NSS were completed by the researcher 30 min after the nCPAP was started and the first saliva sample was taken. The patient follow-up chart and NSS were completed 30 min after applying the swaddling method and the second saliva sample was collected. The data were analyzed using IBM SPSS Statistics 25.0 package software and presented with number, percentage, mean, standard deviation, min-max, and t-test.

RESULTS

The study found that the mean score of the NSS after the intervention (3.52 ± 2.57) was lower than that before the intervention (10.02 ± 2.05) (p < 0.05). The mean saliva cortisol levels of the newborns after the intervention (4.99 ± 1.89) were lower than before the intervention (5.51 ± 1.65) (p < 0.05). The mean heart (135.50 ± 14.15) and respiratory rates (68.07 ± 10.16) of the newborns after the intervention were lower than those before the intervention (140.82 ± 18.11; 72.95 ± 9.06, respectively) (p < 0.05). There was no difference between the mean oxygen saturation of newborns before and after the intervention (p > 0.05).

CONCLUSIONS

The study showed that the swaddling method played a role in reducing the stress levels in newborns who underwent nCPAP. It is recommended that randomized controlled trials examining the effect of swaddling on the stress levels of newborns who underwent nCPAP be conducted.

Efficay of high-flow nasal cannula in the paediatric population: A systematic evidence map

PROBLEM

High-flow nasal cannula (HFNC) has been widely used in paediatric medicine as a non-invasive ventilation mode for respiratory support. However, the differences in its efficacy across different diseases and intervention types remain poorly understood.

ELIGIBILITY CRITERIA

An extensive literature search was performed across multiple academic databases to investigate the systematic reviews and meta-analyses of HFNC.

SAMPLE

This study included 35 systematic reviews and meta-analyses, which collectively examined 355 randomised controlled trials and assessed 51 outcome indicators.

RESULTS

The findings suggest that the existing clinical research evidence predominantly supports the therapeutic efficacy of HFNC. Notably, there is a significant focus on treating acute lower respiratory infection, hypoxaemia, bronchiolitis, and respiratory distress syndrome following extubation. However, concerning the respiratory status, the existing clinical research evidence mainly demonstrates the therapeutic benefits in post-extubation respiratory support and primary respiratory support.

CONCLUSIONS

The research on HFNC has witnessed significant expansion, primarily focusing on respiratory disorders, post-extubation respiratory support, conscious sedation, and related fields. The evidence mapping provides a systematic and comprehensive overview of the available evidence on HFNC therapy in paediatric patients.

IMPLICATIONS

This study systematically and comprehensively assessed the clinical subjects and populations involved in HFNC therapy. Notably, this study analyzed the trends, current status, and evidence gaps of research, and furnished decision-makers and relevant researchers with a more comprehensive reference basis.

Implementation of Kangaroo Care in a Pediatric Cardiac Intensive Care Unit

With supporting the best neurodevelopmental outcomes possible, the doctor of nursing practice project was constructed. An educational program was created for nursing staff discussing the importance of kangaroo care and how to safely facilitate it in the intensive care setting. Following the education completion, kangaroo care was implemented. Data were collected exploring barriers to implementation, discharge on maternal breast milk, and parental feedback.

NICU sensory experiences associated with positive outcomes: an integrative review of evidence from 2015-2020

To inform changes to the Supporting and Enhancing NICU Sensory Experiences (SENSE) program, studies investigating sensory-based interventions in the NICU with preterm infants born ≤32 weeks were identified. Studies published between October 2015 to December 2020, and with outcomes related to infant development or parent well-being, were included in this integrative review. The systematic search used databases including MEDLINE, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, and Google Scholar. Fifty-seven articles (15 tactile, 9 auditory, 5 visual, 1 gustatory/olfactory, 5 kinesthetic, and 22 multimodal) were identified. The majority of the sensory interventions that were identified within the articles were reported in a previous integrative review (1995-2015) and already included in the SENSE program. New evidence has led to refinements of the SENSE program, notably the addition of position changes across postmenstrual age (PMA) and visual tracking starting at 34 weeks PMA.

Abnormal infant neurobehavior and later neurodevelopmental delays in children with critical CHD

Infants with critical CHD have abnormal neurobehavior assessed by the Neonatal ICU Network Neurobehavioral Scales. This retrospective cohort study hypothesized associations between abnormal infant neurobehavior in the first month of life and later neurodevelopmental outcomes at 1-2 years of age. Associations between abnormal infant attention (orienting to and tracking stimuli) on the Neonatal ICU Network Neurobehavioral Scales and later motor, cognitive, and language neurodevelopmental outcomes on the Bayley Scales of Infant Development-III at follow-up were examined with descriptive statistics and univariable and multivariable regression. Multiple imputation was used to account for missing outcome data. 189 infants with critical CHD were included, and 69% had abnormal neurobehavioral attention scores. 58 (31%) returned as toddlers for neurodevelopmental follow-up, of which 23% had motor delay. Abnormal infant attention had high sensitivity (92%, 95% CI 60-100%) but low specificity (36%, 95% CI 23-52%) for later motor delay. Higher infant attention scores were associated with higher later motor scores in univariable analysis (coefficient 3.49, 95% CI 0.52,6.46, p = 0.025), but not in multivariable analyses. Neither cognitive nor language scores were associated with infant attention scores. Lower birth weight and male sex were significantly associated with lower motor scores in multivariable analysis (p = 0.048, 0.007). Although impaired infant attention is interdependent with other clinical and demographic risk factors, it may be a sensitive clinical marker of risk for later motor delay. In children with critical CHD, impaired infant attention may be capturing early signs of abnormal visual-motor neurodevelopment.

The effects of kangaroo mother care on physiological parameters of premature neonates in neonatal intensive care unit: A systematic review

PURPOSE

The effects of Kangaroo mother care (KMC) on physiological parameters in preterm infants have been reported in the literature by experimental and quasi-experimental studies, and varying findings have been presented. The present study was conducted to determine the effects of KMC on the physiological parameters of premature newborns in the Neonatal Intensive Care Unit.

DESIGN AND METHOD

The review was conducted according to the specified keywords by scanning the EBSCO-host, Cochrane Library, Medline, PubMed, ScienceDirect, Web of Science, and TR index databases using the keywords "kangaroo care AND preterm AND vital signs." The pool mean differences (MDs) were calculated, adopting a 95% confidence interval (CIs) using the Stata 16 software for the meta-analysis [PROSPERO: CRD42021283475].

RESULTS

Eleven studies for systematic review and nine studies for meta-analysis, including 634 participants, were found eligible for inclusion. It was determined that the "temperature" (z = 3.21; p = 0.000) and "oxygen saturation" (z = 2.49; p = 0.000) values created a positive effect in general in the kangaroo care group; however, there was no sufficient evidence to state that it affected the "heart rate" (z = -0.60; p = 0.55) and "respiratory rate" (z = -1.45; p = 0.15) values. In the present study, the duration of KMC application had statistically different effects on temperature and oxygen saturation (SpO₂) (p < 0.05). One-hour or shorter applications of KMC had a higher effect on the temperature and oxygen saturation values (1.83; 1.62, respectively).

CONCLUSION

Our results provided references for clinical implications, and the "temperature" and "oxygen saturation (SpO₂)" values created a positive effect in general in the KMC group. However, there was no sufficient evidence to state that it affected the "heart rate" and "respiratory rate" values. The duration of KMC application had statistically different effects on temperature and oxygen saturation. One-hour or shorter applications of KMC had a higher effect on the temperature and SpO₂ values. Longitudinal, randomized, controlled studies examining the effects of KMC on vital signs in premature newborns with vital parameters outside the normal reference range are recommended.

PRACTICE IMPLICATIONS

The goal of the NICU nurse is to improve the infant's well-being. The application of KMC is a unique care for the nurse in maintaining the newborn's well-being. The vital signs of newborns hospitalized in the NICU with critical problems may be out of normal limits. KMC is an essential developmental care practice that ensures that the neonate's vital signs are kept within normal limits by relaxing the neonate, reducing stress, increasing comfort, and supporting interventions and treatments. KMC application is unique for each mother‑neonate pair. Depending on the tolerance of the mother and infant in terms of duration, it is recommended to perform KMC in the NICU under the supervision of a nurse. Neonatal nurses should support mothers in giving KMC in the NICU since KMC has ameliorative effects on the vital signs of premature neonates.

Kangaroo Mother Care for Low-Birth-Weight Babies in Low and Middle-Income Countries: A Narrative Review

In low and middle-income countries (LMICs), the infant mortality rate is much higher than the high-income countries (HICs). The higher infant mortality is due to low birth weight (LBW) a combination of intra-uterine growth retardation (IUGR) and prematurity, which are risk factors for acquiring infectious diseases amongst newborns. Kangaroo mother care (KMC) is a neonatal procedure that is carried out in newborn infants, especially in preterm babies and LBW babies. It is skin-to-skin contact between a mother's bare chest and a stable infant. KMC is an important intervention in reducing infant mortality rates in LMICs. A comprehensive literature and data search was done using key databases like PubMed and Google Scholar. A total of 42 articles out of 1,168 articles were selected for review after screening and elimination of the repeated articles. Through this review we have tried to analyse the benefits of KMC in newborns, the need for the participation of fathers and family members, and the need for implementation of this practice at a broader level by policy formulation in LMICs. We have also discussed the need for KMC for the prevention of infant mortality in LBW newborns in LMICs.

Skin-to-skin contact-An effective intervention on pain and stress reduction in preterm infants

Introduction

The outcomes of pain and stress in preterm infants in the neonatal intensive care units (NICUs) compel the continued search for pain- and stress-reducing interventions.

The objective of the study

To investigate how skin-to-skin contact (SSC) influences chronic pain and stress in preterm infants in the NICU.

Materials and methods

The study included 140 preterm infants in the NICU with gestational age less than 34 weeks. The overall design was a baseline-response design. Urine and saliva were collected before (baseline) and after SSC to measure pain and stress markers by enzyme immunoassay method. The behavioral indicators of chronic pain were assessed using the EDIN (Échelle Douleur Inconfort Nouveau-Né-neonatal pain and discomfort).

Results

There was a significant decrease in the dopamine level in preterm infants after SSC in comparison with baseline values (85.99 [69.35; 112.20] pg/ml vs. 132.20 [104.80; 183.70] pg/ml), p < 0.001. The β-endorphin and serotonin levels increased after SSC (40.09 [26.81; 70.63] pg/ml vs. 29.87 [20.61; 46.94] pg/ml, p = 0.009 and 25.49 [20.45; 40.08] ng/ml vs. 22.30 [15.13; 31.65] ng/ml, p = 0.011, respectively). A significant decrease in cortisol levels in saliva and urine after SSC in comparison with baseline values (0.125 [0.079; 0.225] μg/dl vs. 0.371 [0.188; 1.002] μg/dl, p = 0.000 and 27.06 [14.59; 35.35] ng/ml vs. 35.25 [19.78; 61.94] ng/ml, p = 0.001, with a simultaneous increase of oxytocin level (57.00 [36.55; 88.49] pg/ml vs. 38.20 [28.78; 56.04] pg/ml, p = 0.009 were revealed. The total pain EDIN score in infants after SSC was below 6 points, significantly decreasing compared to the baseline (p < 0.05).

Conclusion

Preterm infants in the NICU experience stress and pain, which were confirmed by the EDIN pain scale and laboratory markers. The level of dopamine and cortisol as pain and stress hormones were reliably high, and normalized after regular SSC. Simultaneously, pain-relieving and anti-stress markers of oxytocin, β-endorphin and serotonin reliably increased in preterm infants in response to the SSC.

Touch Experiences of Preterm Infants During Essential Nursing Care

Purpose: To characterize and quantify touch experienced by preterm infants in the NICU during essential nursing care, identify instances of skin-to-skin touch between infants and caregivers, and identify clinical/demographic variables associated with touch experiences. Design: Cross-sectional study. Sample: Preterm infants (N = 20) born 27-32 weeks post-menstrual age. Main Outcome Variable: Categories of touch during observations. Results: Touch experienced by infants during day and night shifts was primarily direct touch that was further categorized as general handling. During day shifts, 30 percent of direct touch was provided for comfort, but only 9.7 percent of touch was provided exclusively for comfort (i.e., without more intrusive touch). During night shifts, 10.6 percent of direct touch was provided for comfort, and 3 percent was categorized as exclusive comforting touch. Caregivers wore gloves for >89 percent of infant touch. Only the level of respiratory support was associated with touch categories during both shifts.

Effect of the Kangaroo Mother Method after Preterm Delivery on Maternal Stress and Anxiety in the Context of the COVID-19 Pandemic-A Cohort Study

BACKGROUND

The kangaroo mother method (KMM) may benefit infants and mothers in many ways. However, few studies focused on its efficacy on maternal anxiety and stress, especially in the context of the COVID-19 pandemic.

OBJECTIVE

To examine the effect of the kangaroo mother method (KMM) on postnatal stress and anxiety in mothers of preterm infants in neonatal intensive care, in the context of the COVID-19 pandemic.

METHODS

A cohort study of two groups of 56 mother-infant dyads recruited from a neonatal intensive care unit was conducted. Two groups were compared in terms of the mean duration of KMM during the twelve days of the study: the intervention group (mean duration of more than ninety minutes per day) and the control group (less than ninety minutes). Maternal stress was measured using the Parental Stressor: Neonatal Intensive Care Unit (PSS: NICU) scale and STAI E/R questionnaire before and after intervention (KMM). Demographic and other maternal covariates were extracted from medical records. Daily NICU records were used to track the frequency and duration of KMM sessions.

RESULTS

Mothers of the intervention group scored lower on the PSS: NICU and STAI E/R, although no statistically significant differences were found (p > 0.05).

CONCLUSIONS

Contrary to research based on biological and physiological parameters in newborns or performed before the COVID-19 pandemic, the differences found in applying subjective scales in mothers in the context of the COVID-19 pandemic were not significant. Therefore, mothers' perception of physical contact with their preterm infants may not have been as positive due to their fear of transmitting COVID.

Early-life factors associated with neurobehavioral outcomes in preterm infants during NICU hospitalization

BACKGROUND

The aim of this study was to investigate the influence of early-life pain/stress and medical characteristics on neurobehavioral outcomes in preterm infants.

METHODS

A prospective cohort study was conducted with 92 preterm infants (28-32 weeks gestational age [GA]). Early-life pain/stress was measured via the Neonatal Infant Stressor Scale (NISS) during the first 28 days of NICU hospitalization. Neurobehavioral outcomes were evaluated using the NICU Network Neurobehavioral Scale at 36-38 weeks post-menstrual age. Functional regression and machine learning models were performed to investigate the predictors of neurobehavioral outcomes.

RESULTS

Infants experienced daily acute pain/stress (24.99 ± 7.13 frequencies) and chronic events (41.13 ± 17.81 h). Up to 12 days after birth, both higher acute and chronic NISS scores were associated with higher stress scores; and higher chronic NISS scores were also related to lower self-regulation and quality of movement. Younger GA predicted worse neurobehavioral outcomes; GA < 31.57 weeks predicted worse stress/abstinence, self-regulation, and excitability; GA < 30.57 weeks predicted poor quality of movement. A higher proportion of maternal breastmilk intake predicted better self-regulation, excitability, and quality of movement in older GA infants.

CONCLUSIONS

Preterm infants are vulnerable to the impact of early-life pain/stress. Neurobehavioral outcomes are positively associated with increased GA and higher maternal breastmilk intake.

IMPACT

During the first 12 days of life, preterm infant neurobehavioral outcomes were vulnerable to the negative impact of acute and chronic pain/stress. Future research is warranted to investigate the long-term effects of early-life pain/stress on neurobehavioral outcomes. Gestational age remains one of the critical factors to predict neurobehavioral outcomes in preterm infants; older gestational age significantly predicted better neurobehavioral outcomes. Feeding with a higher proportion of maternal breastmilk predicted better neurobehavioral outcomes. Future research is warranted to investigate how maternal breastmilk may buffer the negative effects of early-life pain/stress on neurobehavioral outcomes.

The effect of kangaroo care practice after caesarean section on paternal-newborn interaction: A mixed-methods study in Turkey

OBJECTIVES

The first meeting of the mother with the newborn after the caesarean section is usually delayed due to some reasons in Turkey. Although there are many benefits of applying kangaroo care (KC) between mother and newborn, there are a limited number of studies on the application of KC between newborn and father after caesarean section in international literature. This study was conducted to determine the effect of kangaroo care between father and newborn after caesarean section.

METHOD

A mixed-methods study was used. Data were collected through semi-structured interviews and video recordings. While KC was applied to a couple of the father and the newborn in the experimental group, no application was given to the control group. The study sample consisted of 30 control group participants and 30 experimental group participants, from 60 planned caesarean delivered newborns and their fathers. In this process, newborns' (heart rate, respiratory rate, peripheral oxygen saturation rate, body temperature) and fathers' (feelings and behavior) characteristics were recorded. The data collection complied with the consolidated criteria for reporting qualitative research guidelines.

RESULTS

No significant difference was found between the two groups in terms of newborns' mean heart rate (p>0.005). On the other hand, the respiration rate, oxygen saturation, and the mean body temperature values showed significant differences (p ≤ 0.005). The differences between the two groups were significant in terms of the happiness levels of the father and newborn pair and the calmness of the newborns (p ≤ 0.005).

DISCUSSION

The finding that respiratory rate, oxygen saturation and mean body temperature values were within normal limits in the control group, despite being showed significant differences from the KC group, also supports the benefit of the father's involvement in KC. Almost all of the fathers in the study group reported that KC had a positive effect on their interaction with their newborns and that they were satisfied with the experience. KC should be disseminated and routinely applied.

Clinical practice guideline for kangaroo mother care in preterm and low birth weight infants

Kangaroo mother care has reduced mortality and morbidity in preterm and low birth weight infants and has many benefits, such as promoting breastfeeding. Based on the current evidence in China and international, we developed a clinical practice guideline for kangaroo mother care in preterm and low birth weight infants using the Grading of Recommendations, Assessment, Development and Evaluation and proposed 34 recommendations for 20 key questions. Our goal is to promote the appropriate implementation of kangaroo mother care in clinical practice.

Affective Touch and Regulation of Stress Responses

Much has been documented on the association between stress and health. Both direct and indirect pathways have been identified and explored extensively, helping us understand trajectories from healthy individuals to reductions in well-being, and development of preclinical and disease states. Some of these pathways are well established within the field; physiology, affect regulation, and social relationships. The purpose of this review is to push beyond what is known separately about these pathways and provide a means to integrate them using one common mechanism. We propose that social touch, specifically affective touch, may be the missing active ingredient fundamental to our understanding of how close relationships contribute to stress and health. We provide empirical evidence detailing how affective touch is fundamental to the development of our stress systems, critical to the development of attachment bonds and subsequent social relationships across the life course. We will also explore how we can use this in applied contexts and incorporate it into existing interventions.

A Narrative Review of Kangaroo Mother Care (KMC) and Its Effects on and Benefits for Low Birth Weight (LBW) Babies

Kangaroo mother care (KMC) is a preventative, economical method for infants with low birth weight (LBW). KMC benefits LBW infants in a number of ways. This review standpoints the effect of KMC on the weight gain of LBW neonates. KMC also improves breastfeeding rates during the hospital stay as well as at home. KMC can be provided not only by mothers but also by fathers and other adults in the family. However, it is not routinely practiced in hospitals. Short-term and long-term KMC is beneficial for survival, neurodevelopment, breastfeeding, and mother-infant bonding. Preterm infants are more likely to experience neonatal mortality and morbidity due to acute breathing problems, gastrointestinal problems, autoimmune disorders, and neurological defects as compared to full-term and normal-weight infants. A thorough literature search was conducted using key databases like PubMed and Google Scholar, as well as Medical Subject Heading (MeSH) terms and related keywords. Clinical health experts also believed that implementing KMC would assist mothers in developing more solid emotional bonds with their newborns. As a result, both mothers and their newborns felt more secure, and the babies were more relaxed. KMC was also seen to support the infants' growth and development, which improved the mothers' sense of connection. It is crucial to remember that KMC works better for babies with very low birth weight (VLBW). The mother-child relationship enhances sucking-feeding, and KMC infants have higher means of growth parameters.

Effects of kangaroo care on pain relief in premature infants during painful procedures: A meta-analysis

AIM

This study aimed to evaluate effects of kangaroo care on pain relief in premature infants during painful procedures.

DESIGN

A meta-analysis.

METHODS

Eight databases (Cochrane Library, PubMed, Embase, Web of Science, China Biology Medicine [CBM], China Science and Technology Journal Database [CSTJ], China National Knowledge Infrastructure [CNKI], and WanFang Data) were systematically reviewed from inception to November 2021 for randomized controlled and crossover trials.

RESULTS

Thirteen studies, including 2311 infants (kangaroo care: 1153, control: 1158) were analyzed. Kangaroo care had a moderate effect on pain relief during painful procedures in premature infants at a gestational age of 32-36 + 6 weeks but no effect at 28-31 + 6 weeks. Furthermore, 15 or 30 min of kangaroo care had a moderate effect and could markedly relieve pain at the instant of and 30/60 s after, had a small effect at 90 s after, and no effect at 120 s after the procedure.

PRACTICE IMPLICATIONS

Kangaroo care may be an effective nonpharmacologic alternative therapy to relieve procedural pain in premature infants born at a gestational age of 32-36 + 6 weeks.

The Effectiveness of Kangaroo Mother Care (KMC) on attachment of mothers with premature infants

Objective

Attachment is a socio-emotional relationship between the mother and infant that increases the probability of a preterm infant's survival. This study aimed to evaluate the effectiveness of Kangaroo Mother Care (KMC) on maternal attachments of mothers with premature infants.

Study design

This quasi-experimental study was performed on 100 mothers of premature infants who were admitted to neonatal intensive care units. A questionnaire comprising demographic information and the Maternal Attachment Scale were used as data collection tools. All data analysis was performed using SPSS software version 25. Significant level is considered P < 0.05.

Results

After the intervention, the levels of maternal attachment of mothers in the intervention group were significantly higher than in the control group (47.7 ± 2.9vs. 40.4 ± 5.4, P = 0.003). After the intervention, the infants in the intervention group has a significantly higher number of breastfeeding than the control group (10.6 ± 1.8 vs. 8.2 ± 1.6, P = 0.000). Moreover, the infant of the intervention group had a statistically significant higher weight at discharge time (2164.4 ± 481.1 vs. 1965.2 ± 372, P = 0.042).

Conclusion

The results of the present study showed that Kangaroo Mother Care can be used to improve the maternal attachments in mothers with premature infants. It improves the breastfeeding and weight gain status in infants as well.

Skin-to-skin contact to support preterm infants and reduce NICU-related stress

OBJECTIVE

Hospitalization in the neonatal intensive care unit (NICU) with numerous painful medical interventions, being separated from parents, leads to the high risk of chronic stress for preterm infants. Today, many NICUs use more appropriate developmental care and pain management, but the early and long-term outcomes of stress in these vulnerable infants require searching for more stress-reducing interventions in neonatal care. The objective of the study was to investigate how skin-to-skin contact (SSC) can influence the biologic stress levels in preterm infants in the NICU by assessing cortisol and oxytocin levels.

PARTICIPANTS AND METHODS

The study included 71 preterm infants with gestational age less than 34 + 0/7 weeks who were recruited from level III NICU. The overall design was a baseline-response design. Saliva and urine were collected before (baseline) and after skin-to-skin contact to measure salivary cortisol and urinary oxytocin by enzyme immunoassay method.

RESULTS

The infants' baseline hormonal status was represented by the following indicators: the level of salivary cortisol was 0.402 [0.227; 1,271] μg/dl, urinary oxytocin 48.88 [32.97; 88.11] pg/ml. There was a decrease in salivary cortisol levels to 0.157 [0.088; 0.351] μg/dl compared to baseline (p ˂ 0.001) with a simultaneous increase of the urinary oxytocin level -73.59 [45.18; 108.8] pg/ml (p = 0.028) in response to SSC.

CONCLUSION

Preterm infants in the NICU experience significant stress, characterized by hormonal imbalance: an increased level of the stress hormone cortisol and a decreased level of the anti-stress hormone oxytocin. Skin-to-skin contact helps to ameliorate the hormonal stress in preterm infants by activating the oxytocin release with simultaneous reduction of cortisol secretion.

Benefits of Kangaroo Mother Care on the Physiological Stress Parameters of Preterm Infants and Mothers in Neonatal Intensive Care

It is well documented that the stress of separation of mother and baby can lead to short-term physiological instability as well as neurological, sociological or psychological consequences that may last a lifetime. Objective: The goal was to estimate the effect of kangaroo mother care (KMC) on physiological and biochemical parameters of preterm infant stress and maternal stress in neonatal intensive care. Methods: The investigation involved 112 preterm infants. Two groups were compared according to the mean duration of KMC during 12 days of study: the KMC group (mean duration more than 90 min daily) and the control group (less than 90 min). Results: Kangaroo mother care for more than 90 min on average per day in preterm infants is associated 12 days after the intervention with lower mean cortisol levels (p = 0.02), greater weight gain and less need for parenteral nutrition in preterm infants, as well as less postpartum depression (p = 0.02) and lower cortisol levels (p = 0.002) in the mothers of preterm infants. Conclusions: This study suggests that KMC can be used to improve the stress of preterm infants and their mothers, and that the greater weight gain observed in these preterm infants could contribute to a shorter average hospital stay and lower healthcare expenditure.

A Systematic Review of the Effects of Skin-to-Skin Contact on Biomarkers of Stress in Preterm Infants and Parents

BACKGROUND

Premature infants and their parents experience significant stress related to separation and lifesaving procedures. While evidence suggests that skin-to-skin contact (SSC) is a stress-reducing intervention for both neonates and parents, the mechanisms that underlie its efficacy are not well understood.

OBJECTIVE

Purpose of this systematic review is to summarize the current state of knowledge on changes in biomarkers (ie, oxytocin [OT], cortisol, hypoxanthine, xanthine, uric acid, and allantoin), associated with SSC in premature infants and parents, that may reflect physiologic responses to stress.

METHODS

A comprehensive literature search was conducted from 1990 to 2020. Studies were selected using prespecified inclusion and exclusion criteria.

RESULTS

Of the 175 studies identified, only 19 are included in this review. Ten studies evaluated only infants, 2 evaluated only parents, and 7 evaluated for changes in biomarkers in both infants and parents. Cortisol was the most common biomarker evaluated. While changes in infants' cortisol levels were highly variable, in 55% of the parent studies, parent cortisol levels decreased following SSC. In both parents and infants, OT levels decreased following SSC. Only 1 study found that allantoin levels were significantly lower in infants who received SSC.

IMPLICATIONS FOR PRACTICE AND RESEARCH

While evidence suggests the numerous benefits of SSC, additional research is needed to identify the optimal biomarker to determine the mechanisms that underlie these effects. The use of novel biomarkers (eg, gene expression changes microbiome) may provide new insights into the mechanisms that underlie the efficacy of SSC.Video Abstract available at:https://journals.lww.com/advancesinneonatalcare/Pages/videogallery.aspx?autoPlay=false&videoId=48.

The effectiveness of Kangaroo Mother Care in hospitalization period of preterm and low birth weight infants: systematic review and meta-analysis

OBJECTIVE

To evaluate the effectiveness of kangaroo mother care (KMC) in reducing the length of hospital stay of preterm and/or low birth weight infants.

SOURCE

Cochrane Library, Pubmed, Embase, LILACS, and Scielo. Randomized clinical trials without time or language limit were included. The intervention was the KMC in preterm and/or low birth weight infants born in health facilities compared to conventional care. The article selection was performed by a pair of reviewers independently. The methodological quality assessment was performed using the tool Risk of Bias 2.

SUMMARY OF THE FINDINGS

Eight hundred and sixty-four citations were identified and 12 were selected for data extraction. There was a reduction in the length of hospital stay in days in the KMC group compared to the conventional care group, with a statistically significant difference (MD -1.75, 95% CI -3.22 to -0.28). The subgroup that underwent the intervention for more than six hours daily did not show a statistical difference for the length of hospital stay outcome (MD -0.79, 95% CI -2.52 to 0.90), while the subgroup that underwent the intervention for less than six hours daily showed a reduction in this outcome with a statistically significant difference (MD -4.66, 95% CI -7.15 to -2.17).

CONCLUSIONS

KMC is a safe and low-cost intervention that has been shown to be effective in reducing the length of hospital stay of preterm and/or low birth weight infants.

Comparison of Chest-to-Back Skin-to-Skin Contact and Chest-to-Chest Skin-to-Skin Contact on the Risk of Oxygen Desaturation and Change in Heart Rate in Low Birth Weight and/or Premature Babies: A Randomized Controlled Clinical Trial

Chest-to-chest (CC) skin-to-skin contact (SSC) is a widely used method of SSC to prevent low birth weight (LBW) and/or premature babies with the risk of hypothermia. However, very recently, a study has also shown that the chest-to-back (CB) SSC is also useful for such a purpose. It is also evident that CC SSC enhances the cardiorespiratory performance of LBW and/or premature babies from the risk of cold stress. However, whether babies kept in CB SSC have the risk of clinically relevant decreases of oxygen saturation or critical changes of the baby heart rate comparing the two SSC methods has been studied hardly. Thus, we assessed the risk of oxygen desaturation and changes in babies' heart rate among LBW and/or premature babies kept in CB SSC compared to the standard. In this study, we enrolled 46 LBW and/or premature babies born between 32 and 37 completed weeks of gestation. We used a parallel-group randomized controlled clinical trial. Peripheral arterial blood oxygen saturation (SpO2) and heart rate (HR) were measured using an OxiMaxN-600X Pulse Oximeter. We transformed these measurements into stability of the cardiorespiratory system in premature infant (SCRIP) scores. We applied a generalized estimating equation model to analyze the data. No statistically significant difference was observed between babies kept in CB SSC compared to babies kept in CC SSC in either blood oxygen saturation or heart rate (P > 0.05). Thus, the CB SSC can be used as one possible way to care for LBW and preterm babies in the kangaroo mother care. We suggest more studies before scaling up the approach in routine care.

Factors Impacting Long-Term Gastrostomy Tube Dependence in Infants with Congenital Heart Disease

BACKGROUND

Infants with congenital heart disease (CHD) often experience oral feeding intolerance requiring gastrostomy (GT). Complications related to GT use are common. The study aim was to identify factors associated with continued GT use at one-year.

METHODS

A retrospective cohort study was performed at a tertiary children's hospital using the Society of Thoracic Surgeons database and patients' electronic medical record. Infants <1-year with CHD who underwent cardiac and GT surgery between January 2014-October 2019 were identified. Patient demographics, preoperative feeding, clinical variables, and GT use at one-year was evaluated. A separate cohort discharged with a nasogastric tube (NGT) was identified for longitudinal comparisons.

RESULTS

Of 137 infants who received a GT, 115 (84%) continued using their GT at one-year. Factors associated with continued GT use included lower median percent of goal oral feeding before GT placement (0% IQR 0-6.5 versus 3.7% IQR 0-31), prolonged hospitalization after GT placement (36% versus 14%, P-value = 0.048), and failure to take oral feeds at discharge (69% versus 27%, P-value <0.001). There was no difference in demographics or clinical comorbidities between groups. Clinic/emergency room visits for GT complications were common (72%). Eight infants discharged with a NGT did not require GT placement.

CONCLUSIONS

Patients with CHD tolerating minimal oral nutrition before GT placement, prolonged hospitalization after GT, and difficulty with oral feeds at discharge were more likely to use their GT at 1-year. Outpatient NGT feeding is feasible for select infants with CHD. Efforts to optimize care for this complex, device-dependent population are warranted to minimize risks and facilitate family engagement for long-term care.

Mapping the Field in Stress, Anxiety, and Postpartum Depression in Mothers of Preterm Infants in Neonatal Intensive Care

Objective: The main aim of this study was to describe and conduct a bibliometric analysis of the state of research on stress, anxiety, and postpartum depression in mothers of preterm infants in the Neonatal Intensive Care Unit. Background: Women affected by premature births are particularly exposed to mental health difficulties in the postpartum period. The desire to comprehend and the growing interest in research on stress, anxiety, and postpartum depression in mothers of preterm infants in neonatal intensive care have led to a substantial rise in the number of documents in this field over the last years. Thus, it makes it vital to regularly review the state of knowledge on this phenomenon in order to identify progress and constraints, to stimulate reflection, and to encourage progress in future research. Method: This study examined 366 articles published in the Scopus database (1976–2020). Keyword analysis was also used to identify hot research trends to be developed in future studies. This study complies with the PRISMA-Scr guidelines for quality improvement research in the EQUATOR network. Results: Our results reveal that research in this field is in a period of high production and allows this flourishing body of work to be organized into different periods, highlighting the most important themes. In such a way, our research enriches the lively field by presenting a comprehensive understanding of the field. Discussion: The key contribution of this study is the development of a conceptual map of research on stress, anxiety, and postpartum depression in mothers of preterm infants in neonatal intensive care units.

Parent-Infant Skin-to-Skin Contact and Stress Regulation: A Systematic Review of the Literature

Several studies have focused on neonatal maternal separation (MS) to investigate behavioural and neuroendocrine reactions to lack of contact, but only a few have focused on early separation in the first days or weeks after birth. This literature review investigates the vital importance of contact and touch by exploring how skin-to-skin contact (SSC) regulates stress in the mother-infant relationship. Various databases such as PubMed, Scopus, and ScienceDirect were searched for literature published between 2015 and 2020. From 1141 articles, 22 were declared eligible. The reviewed articles showed how SSC regulates child stress by biological indicators such as the autonomic nervous system (ANS), heart rate variability (HRV), cortisol, and oxytocin. This research concludes the importance of SSC for stress regulation, especially during the COVID-19 pandemic. With no research to date indicating a possible risk of neonatal COVID-19 transmission following SSC, SSC should continue to be practiced for all women, as recommended by the WHO.

Positive Effects of Kangaroo Mother Care on Long-Term Breastfeeding Rates, Growth, and Neurodevelopment in Preterm Infants

Background and Objectives: Kangaroo mother care (KMC) benefits preterm infants' health through increasing breastfeeding, but the longitudinal effects of KMC remain unknown. This study investigates the impact of KMC on breastfeeding and health outcomes in Chinese preterm infants. Methods: A longitudinal randomized controlled study was conducted with 79 preterm infant-mother dyads. The KMC group (n = 36) was provided 2.5 hours/day KMC during the neonatal intensive care unit (NICU) hospitalization, while the control group (n = 43) received standard care. Infant's feeding regimens and physical growth were documented daily at NICU. Physical growth and Neonatal Behavioral Neurological Assessment were measured at 40 weeks, 3 months, and 6 months of corrected age (CA). Breastfeeding outcomes were documented at 6 months of CA. Results: Compared with the control group, KMC infants received higher mothers' milk proportion during hospitalization (B = 0.16, confidence interval [CI] = [0.11-0.21]) and less feeding intolerance at discharge (odds ratio [OR] = 0.11, CI = [0.02-0.43]); and higher exclusive breastfeeding proportion (OR = 14.6, CI = [3.5-60.9]) at 6 months CA. KMC infants also had significant increased body weight and body length at hospital discharge; and more increases of body weight, body length, and head circumference in follow-ups. The neurobehavioral score was also higher in the KMC group compared to the control group over time. Conclusions: Longitudinal KMC effects are significant in promoting preterm infants' breastfeeding outcomes, growth, and neurodevelopment. Early initiation of KMC practice is highly recommended to the parent-infant population in Chinese NICUs to promote breastfeeding and developmental outcomes.

Family integrated care in single family rooms for preterm infants and late-onset sepsis: a retrospective study and mediation analysis

BACKGROUND

During hospital stay after birth, preterm infants are susceptible to late-onset sepsis (LOS).

OBJECTIVE

To study the effect of family integrated care in single family rooms (SFRs) compared to standard care in open bay units (OBUs) on LOS. Peripheral or central venous catheters (PVCs/CVCs) and parenteral nutrition (PN) were investigated as potential mediators. Secondary outcomes were length of stay, exclusive breastfeeding at discharge, and weight gain during hospital stay.

METHODS

Single-center retrospective before-after study with preterm infants admitted ≥3 days.

RESULTS

We studied 1,046 infants (468 in SFRs, 578 in OBUs, median gestational age 35 weeks). SFRs were associated with less LOS (adjusted odds ratio (OR) 0.486, 95% confidence interval (CI): 0.293; 0.807, p = 0.005). PVCs (indirect effect -1.757, 95% CI: -2.738; -1.068), CVCs (indirect effect -1.002, 95% CI: -2.481; 0.092), and PN (indirect effect -1.784, 95% CI: -2.688; -1.114) were possible mediators of the effect. PN was the main mediator of the effect of SFRs on LOS. We found shorter length of stay (median length of stay in SFRs 10 days and in OBUs 12 days, adjusted β -0.088, 95% CI: -0.159; -0.016, p = 0.016), but no differences in weight gain or exclusive breastfeeding at discharge.

CONCLUSIONS

SFRs were associated with decreased incidences of LOS and shorter length of hospital stay. The positive effect of SFRs on LOS was mainly mediated through a decreased use of PN in SFRs.

IMPACT

Family integrated care (FICare) in single family rooms for preterm infants was associated with less late-onset sepsis events during hospital stay and a shorter length of hospital stay after birth. FICare in single family rooms was associated with less use of peripheral or central venous catheters and parenteral nutrition. Mediation analysis provided insights into the mechanisms underlying the effect of FICare in single family rooms on late-onset sepsis and helped explain the differences observed in late-onset sepsis between FICare in single family rooms and open bay units. The reduction in late-onset sepsis in FICare in single family rooms was mediated by a reduced use of intravenous catheters and parenteral nutrition.
