Impact of kangaroo mother care on cerebral blood flow of preterm infants

Should Fathers Also Do Kangaroo Care?

OBJECTIVES

The aim of the study is to compare the effect of maternal and paternal Kangaroo care (KC) on vital signs and cerebral oxygen saturation (rSO2) parameters.

METHODS

This randomized study included 35 preterm infants born at 32 weeks gestation or earlier. The body temperature, respiratory rate, heart rate, oxygen saturation (sPO2), and cerebral oxygen saturation (rSO2) were measured at the postnatal 35th week of gestation during three periods: in the incubator before KC, during KC with the mother or father, and in the incubator after KC. The measured parameters of the three periods were compared within each group (mother or father) and between the groups (mother and father).

RESULTS

There was no statistically significant difference between the vital signs during the three periods, both in the mother and father groups, and between the parents.The rSO2 values increased significantly in both parents (p <0.001) during and after KC. When we compared parents, rSO2 values were significantly higher during (p = 0.015) and after (p = 0.046) mother KC.

CONCLUSION

The difference between M-KC and F-KC can be ignored as the cerebral near infra-red spectroscopy values are within normal limits. The active participation of fathers in KC should be encouraged by health professionals in all NICUs.

KEY POINTS

· * The vital signs during and after kangaroo care, both in the mother and father groups, were similar.. · * The rSO2 values increased significantly in both parents during and after kangaroo care, favoring the mother.. · * This difference can be ignored as the cerebral near-infra-red spectroscopy values are within normal limits in both groups, and the participation of fathers in kangaroo care should be encouraged..

Improving the Treatment of Neonatal Sepsis in Resource-Limited Settings: Gaps and Recommendations

Neonatal sepsis causes significant global morbidity and mortality, with the highest burden in resource-limited settings where 99% of neonatal deaths occur. There are multiple challenges to achieving successful treatment of neonates in this setting. Firstly, reliable and low-cost strategies for risk identification are urgently needed to facilitate treatment as early as possible. Improved laboratory capacity to allow identification of causative organisms would support antimicrobial stewardship. Antibiotic treatment is still hampered by availability, but also increasingly by antimicrobial resistance - making surveillance of organisms and judicious antibiotic use a priority. Finally, supportive care is key in the management of the neonate with sepsis and has been underrecognized as a priority in resource-limited settings. This includes fluid balance and nutritional support in the acute phase, and follow-up care in order to mitigate complications and optimise long-term outcomes. There is much more work to be done in identifying the holistic needs of neonates and their families to provide effective family-integrated interventions and complete the package of neonatal sepsis management in resource-limited settings.

Changes in cerebral blood flow parameters among preterm 30-34 week neonates who are initiated on kangaroo mother care - A prospective analytical observational study

BACKGROUND

Kangaroo mother care (KMC) is recommended standard of care for preterm neonates. They are vulnerable for cerebral blood flow (CBF) fluctuations linked to intraventricular hemorrhage and periventricular leukomalacia, which have implications on neurodevelopment. This study was designed to document any change in CBF in middle cerebral artery (MCA) of stabilized preterm 30-34 weeks neonates who are initiated on KMC.

METHODS

We designed a prospective analytical observational study in a tertiary care neonatal unit. We enrolled 30-34 weeks preterm neonates eligible for KMC after their stabilization (n = 40). CBF was measured in supine position via right MCA Doppler through the temporal window before any KMC, after 2 h of 1st KMC session and following 24 h of 1st session. CBF was quantified in terms of pulsatility index (PI), Resistive Index (RI), peak systolic velocity (PSV), end-diastolic velocity (EDV), mean velocity (MV) and values were compared against the existing normative values.

RESULTS

Mean gestation of study population was 31.91 weeks with a mean birth weight of 1432.75 g. Median day of initiation of KMC was 7 days with mean duration of KMC on day 1 was 4.56 h. We could find statistically significant decrease in the values of PI and RI from 90th centile towards 50th centile of normative values with a mean difference of 0.22 (99 % CI 0.02-0.43, p 0.005) for PI and 0.05 (99 % CI 0.02-0.07, p = 0.000) for RI post the first session of KMC. Following 24 h of 1st KMC session, we could find a significant increase in values of PSV, EDV and MV comparing values of pre-initiation with day 2 pre-KMC but values of PI and RI were not significantly different.

CONCLUSION

CBF among 30-34 week preterm neonates tend to optimize after initiation of KMC.

Effect of Kangaroo Mother Care on Cerebral Hemodynamics in Preterm Neonates Assessed by Transcranial Doppler Sonography in Middle Cerebral Artery

Objective

To study the effect of KMC in premature newborns on cerebral hemodynamics in the middle cerebral artery (MCA) using transcranial doppler sonography.

Methods

In this descriptive study, 40 clinically stable preterm neonates admitted to the neonatal intensive care unit of our institute and undergoing Kangaroo mother care (KMC) were enrolled. Physiological and cerebral blood flow parameters of MCA were obtained by using transcranial doppler sonography at baseline, at 60 minutes of KMC, and after 60 minutes of stopping KMC.

Results

Of the 40 enrolled neonates (24 males), the mean (SD) birth weight, gestation age, and postnatal age were 1698.25 (495.44) g, 33.00 (1.67) wk, and 6.80 (4.51) days, respectively. The mean (SD) cerebral blood flow velocities increased (peak systolic velocity (PSV), P=0.03; end diastolic velocity, P<0.001; mean velocity, P<0.001) and doppler indices decreased (resistive index, P=0.001; pulsatility index, P<0.001) significantly; whereas, heart rate (P<0.001) decreased but SpO2 (P=0.001) and mean blood pressure (P=0.003) increased significantly at 60 minutes of KMC as compared to baseline. Sixty minutes after stopping KMC, all parameters (except PSV) were higher than baseline, indicating post KMC effect.

Conclusion

KMC improves cerebral hemodynamics in clinically stable preterm neonates.

The efficacy of Kangaroo-Mother care to the clinical outcomes of LBW and premature infants in the first 28 days: A meta-analysis of randomized clinical trials

Objective

The objective of this study was to systematically determine the benefits of Kangaroo-Mother Care (KMC) on the clinical outcomes of low birthweight (LBW) and preterm infants.

Methods

For this study, the following databases were retrieved for articles published until November 2021: PubMed, Web of Science, EBSCO, and the Cochrane library. The primary clinical outcome was mortality between enrollment and 28 days. The secondary clinical outcomes were the mean duration of hospital stay, hypothermia, sepsis, exclusive breastfeeding at the end of the neonatal period, and exclusive breastfeeding at discharge.

Results

We conducted a meta-analysis, which included 17 RCTs, involving overall 17,668 participants. The results of this meta-analysis showed that KMC could reduce the primary clinical outcome of mortality between enrollment and 28 days (RR: 0.80, 95% Cl: 0.71-0.91, p < 0.01). For the secondary clinical outcomes, KMC had a varying degree of benefits on the mean duration of hospital stay (SMD: -0.96, 95% Cl: -1.02-0.90, p < 0.001), hypothermia (RR: 0.45, 95% Cl: 0.27-0.75, p < 0.01), and sepsis (RR: 0.79, 95% Cl: 0.70-0.89, p < 0.001). The exclusive breastfeeding at the end of the neonatal period and exclusive breastfeeding at discharge of KMC had benefits, which was not statistically different though (OR: 2.16, 95% Cl: 0.55-8.41, p = 0.27; OR: 1.16, 95% Cl: 0.82-1.64, p = 0.39, respectively).

Conclusions

KMC was decreased mortality in LBW and premature infants between enrollment and 28 days. In addition, KMC also had a favorable effectiveness on the secondary clinical outcomes, such as mean duration of hospital stay, hypothermia, sepsis. Moreover, KMC also had a slight effectiveness on exclusive breastfeeding at the end of the neonatal period and exclusive breastfeeding at discharge.

Sensory-based interventions in the NICU: systematic review of effects on preterm brain development

BACKGROUND

Infants born preterm are known to be at risk for abnormal brain development and adverse neurobehavioral outcomes. To improve early neurodevelopment, several non-pharmacological interventions have been developed and implemented in the neonatal intensive care unit (NICU). Sensory-based interventions seem to improve short-term neurodevelopmental outcomes in the inherently stressful NICU environment. However, how this type of intervention affects brain development in the preterm population remains unclear.

METHODS

A systematic review of the literature was conducted for published studies in the past 20 years reporting the effects of early, non-pharmacological, sensory-based interventions on the neonatal brain after preterm birth.

RESULTS

Twelve randomized controlled trials (RCT) reporting short-term effects of auditory, tactile, and multisensory interventions were included after the screening of 1202 articles. Large heterogeneity was identified among studies in relation to both types of intervention and outcomes. Three areas of focus for sensory interventions were identified: auditory-based, tactile-based, and multisensory interventions.

CONCLUSIONS

Diversity in interventions and outcome measures challenges the possibility to perform an integrative synthesis of results and to translate these for evidence-based clinical practice. This review identifies gaps in the literature and methodological challenges for the implementation of RCTs of sensory interventions in the NICU.

IMPACT

This paper represents the first systematic review to investigate the effect of non-pharmacological, sensory-based interventions in the NICU on neonatal brain development. Although reviewed RCTs present evidence on the impact of such interventions on the neonatal brain following preterm birth, it is not yet possible to formulate clear guidelines for clinical practice. This review integrates existing literature on the effect of sensory-based interventions on the brain after preterm birth and identifies methodological challenges for the conduction of high-quality RCTs.

Review of Kangaroo Mother Care in the Middle East

Mothers and newborns have a natural physiological requirement to be together immediately after birth. A newborn has a keen sense of smell and will instinctively seek out the mother’s nipple and begin breastfeeding if placed skin-to-skin with her. This practice is known as Kangaroo Mother Care (KMC). It was first suggested in 1978 and has been recommended by the World Health Organization (WHO) as a means to ensure successful breastfeeding. It is well documented that KMC is associated with positive breastfeeding outcomes, particularly in cases where breastfeeding is exclusive and, on average, continued for 3 months or longer. Studies of infant nutrition and breastfeeding have shown the importance of immediate, uninterrupted skin-to-skin contact between newborn and mother following vaginal birth. This practice is also recommended for mothers who give birth via cesarean section, once the newborn is stable. The rate of breastfeeding is still suboptimal in Middle Eastern countries, in light of the WHO’s recommendation that mothers should exclusively breastfeed for the first six months and continue breastfeeding for up to two years. To increase the rate of breastfeeding, practices should be promoted that have been shown to improve outcomes, such as KMC. However, little is known about this important practice in the region. The aim of this study was to shed light on KMC-related studies conducted in the Middle East between January 2010 and January 2022. Specifically, this review examines breastfeeding practice rates for the first 6 months of birth, and evidence of KMC practices, by country and type of study design. The research terms used for this review were “skin to skin”, “Skin to skin contact”, and “Kangaroo Mother Care”, focusing on “Middle East”, “Eastern Mediterranean”, “Arabian Gulf”, “Arab”, and “GCC”.

Neuroscience meets nurture: challenges of prematurity and the critical role of family-centred and developmental care as a key part of the neuroprotection care bundle

Advances in neonatal-perinatal medicine have resulted in increased survival at lower gestations. Although the incidence of germinal matrix haemorrhage-intraventricular haemorrhage and cystic periventricular leucomalacia is reducing, a new phenotype of preterm brain injury has emerged consisting of a combination of destructive and dysmaturational effects. Consequently, severe neurological disability is reported at a lower rate than previously, but the overall morbidity associated with premature birth continues to present a large global burden and contributes significantly to increased financial costs to health systems and families. In this review, we examine the developmental milestones of fetal brain development and how preterm birth can disrupt this trajectory. We review common morbidities associated with premature birth today. Although drug-based and cell-based neuroprotective therapies for the preterm brain are under intense study, we outline basic, sustainable and effective non-medical, family-centred and developmental care strategies which have the potential to improve neurodevelopmental outcomes for this population and need to be considered part of the future neuroprotection care bundle.

The Feasibility of Kangaroo Care and the Effect on Maternal Attachment for Neonates in a Pediatric Cardiac Intensive Care Unit

BACKGROUND

As survival rates in neonates with congenital heart disease have improved, research has shown they are at an increased risk for brain injury and neurodevelopmental delay. One intervention shown to have a positive impact on the development in premature and full-term newborns, as well as a positive impact on mother-infant relationship, is kangaroo care (KC). There is limited evidence to support the use of KC in infants with congenital heart disease, some of who may also be premature.

PURPOSE

The purpose of this study was to examine the safety and feasibility of introducing KC for neonates with congenital heart disease in the pediatric cardiac intensive care unit.

METHODS

A descriptive observational feasibility study was employed to evaluate the safety and efficacy of KC for this population.

RESULTS

There were 25 neonates included with 60 sessions of KC. There were no adverse events including line and tube dislodgments and physiological instability related to the use of KC.

IMPLICATIONS FOR PRACTICE

This study found KC to be safe and feasible for neonates with KC.

IMPLICATIONS FOR RESEARCH

This is the first study examining the feasibility and safety of KC in this vulnerable population of neonates. Further research should be conducted using a quasi-experimental design to investigate neurodevelopmental outcomes with a larger sample of patients.

Impact of Skin-to-Skin Parent-Infant Care on Preterm Circulatory Physiology

OBJECTIVES

To ascertain the impact of skin-to-skin care between parents and infants on cardiac function and cerebral blood flow in preterm infants.

STUDY DESIGN

We undertook a prospective study of 40 self-ventilating preterm infants at a quaternary center and assessed cardiac performance and cerebral blood flow. Assessments were carried out two hours before skin-to-skin care and then 60 minutes after skin-to-skin care (with the infant still on parent and turned supine).

RESULTS

Infants were 30.5 ± 0.6 weeks' gestational age and 1378 ± 133 g birthweight. Axillary temperature noted a nonsignificant increase during skin-to-skin care from 36.7 ± 0.07°C to 36.9 ± 0.07°C (P = .07). Cardiac contractility (right ventricular fractional area change [26.5% ± 0.3% vs 27.8% ± 0.4; P < .001] and tricuspid annular plane systolic excursion [0.73 ± 0.03 cm vs 0.77 ± 0.03 cm; P = .02]) increased significantly, coincident with decreased measures of pulmonary vascular resistance. An increase in systemic cardiac output was associated with increased cerebral blood flow and reduced middle cerebral artery resistive index (0.81 ± 0.02 vs 0.74 ± 0.02; P = .0001).

CONCLUSIONS

We documented a significant circulatory beneficial adaptation to a common neonatal practice. These findings align with previously documented physiologic benefits in cardiorespiratory stability and cardiac rhythm in preterm infants, and may be mediated through modulation of the autonomic nervous system.

Positive Social Interactions in a Lifespan Perspective with a Focus on Opioidergic and Oxytocinergic Systems: Implications for Neuroprotection

In recent years, a growing interest has emerged in the beneficial effects of positive social interactions on health. The present work aims to review animal and human studies linking social interactions and health throughout the lifespan, with a focus on current knowledge of the possible mediating role of opioids and oxytocin. During the prenatal period, a positive social environment contributes to regulating maternal stress response and protecting the fetus from exposure to maternal active glucocorticoids. Throughout development, positive social contact with the caregiver acts as a “hidden regulator” and promotes infant neuroaffective development. Postnatal social neuroprotection interventions involving caregiver–infant physical contact seem to be crucial for rescuing preterm infants at risk for neurodevelopmental disorders. Attachment figures and friendships in adulthood continue to have a protective role for health and brain functioning, counteracting brain aging. In humans, implementation of meditative practices that promote compassionate motivation and prosocial behavior appears beneficial for health in adolescents and adults. Human and animal studies suggest the oxytocinergic and opioidergic systems are important mediators of the effects of social interactions. However, most of the studies focus on a specific phase of life (i.e., adulthood). Future studies should focus on the role of opioids and oxytocin in positive social interactions adopting a lifespan perspective.

Influence of maternal factors on the successful outcome of kangaroo mother care in low birth-weight infants: A randomized controlled trial

BACKGROUND

Kangaroo mother care (KMC) is associated with positive neonatal outcomes. Studies demonstrated significant influence of maternal factors on the success of applying KMC.

AIM

To determine maternal factors that influence on anthropometric parameters in low birth weight babies that received kangaroo mother care.

METHODS

This is a randomized controlled study that involved low birth weight newborns. We randomly assigned newborns into two groups; a group who received KMC and a group who received conventional care. Maternal factors were recorded. We followed weight, length, and head circumferences of newborns for thirty days.

RESULTS

A total of 40 newborns were included. Weight parameters were significantly higher in the KMC group than the conventional group. From maternal characteristics, only gestational age was found to influence increased head circumference in KMC group (p = 0.035); however, it did not affect the increase in weight or length. Maternal age, parity, education, mode of delivery, fetal sex, and initial Apgar score did not influence growth parameters in either groups.

CONCLUSION

KMC was associated with increased weight gain in LBW infants. Gestational age influences head growth in infants who received KMC.

Advances in pediatrics in 2014: current practices and challenges in allergy, gastroenterology, infectious diseases, neonatology, nutrition, oncology and respiratory tract illnesses

Major advances in the conduct of pediatric practice have been reported in the Italian Journal of Pediatrics in 2014. This review highlights developments in allergy, gastroenterology, infectious diseases, neonatology, nutrition, oncology and respiratory tract illnesses. Investigations endorse a need to better educate guardians and improve nutritional management in food allergy. Management of hyperbilirubinemia in neonates and of bronchiolitis have been improved by position statements of scientific societies. Novel treatments for infant colic and inflammatory bowel diseases have emerged. Studies suggest the diagnostic utility of ultrasonography in diagnosing community-acquired pneumonia. Progress in infectious diseases should include the universal varicella vaccination of children. Recommendations on asphyxia and respiratory distress syndrome have been highlighted in neonatology. Studies have evidenced that malnutrition remains a common underestimated problem in developing countries, while exposure to cancer risk factors in children is not negligible in Western countries. Advances in our understanding of less common diseases such as cystic fibrosis, plastic bronchitis, idiopathic pulmonary hemosiderosis facilitate diagnosis and management. Researches have led to new therapeutic approaches in patent ductus arteriosus and pediatric malignancies.
