Effect of early kangaroo mother care on time to full feeds in preterm infants - A prospective cohort study

Skin-to-skin care (SSC) for term and preterm infants

Skin-to-skin care (SSC) is an important part of parent and infant care during the neonatal period and into infancy. SSC should be initiated immediately after birth and practiced as a standard of care in all settings, as well as in the home. There is strong evidence that SSC has a positive effect on breastfeeding and human milk feeding in both term and preterm infants, as well as on mortality, cardiopulmonary stability, and thermoregulation. SSC reduces pain and infant stress, enhances parent-infant bonding, has neurodevelopmental benefits, and has positive effects on parental mental health. The safety and feasibility of providing SSC has been established in term and preterm infants, and SSC is recommended as best practice for all infants. The benefits of SSC outweigh the risks in most situations, and despite challenges, care providers should implement procedures and accommodations to ensure that SSC occurs as a safe and positive experience for the parent, family, infant, and health care team. This statement includes all families as defined and determined by themselves, and recognizes that health communication, language, and terminology must be individualized to meet specific family needs by the health care team.

Les soins peau-à-peau chez les nourrissons à terme et prématurés

Les soins peau-à-peau (SPP) sont un aspect important des soins au parent et au nourrisson pendant la période néonatale et la première enfance. Ils doivent être entrepris immédiatement après la naissance et faire partie des soins standards dans tous les milieux, y compris à la maison. Selon de solides données probantes, les SPP ont un effet positif sur l'allaitement et l'alimentation par du lait humain, tant chez les nourrissons à terme que prématurés, de même que sur la mortalité, la stabilité cardiorespiratoire et la thermorégulation. Les SPP réduisent la douleur et le stress chez les nourrissons, accroissent l'attachement entre le parent et son nourrisson et ont des effets bénéfiques sur le neurodéveloppement de l'enfant ainsi que sur la santé mentale des parents. Le caractère sécuritaire et la faisabilité des SPP sont établis chez les nourrissons à terme et prématurés, et ces soins sont recommandés dans le cadre d'une pratique exemplaire auprès de tous les nourrissons. Les avantages des SPP sont supérieurs aux risques dans la plupart des situations, et malgré les défis qui y sont associés, les dispensateurs de soins devraient adopter des protocoles et prévoir des adaptations pour s'assurer que les SPP soient une expérience positive et sécuritaire pour le parent, la famille, le nourrisson et l'équipe soignante. Le présent document de principes s'adresse à toutes les familles, telles qu'elles se définissent et se déterminent elles-mêmes, et tiennent compte de l'importance de personnaliser la communication, le langage et la terminologie en matière de santé pour que l'équipe soignante réponde aux besoins particuliers de la famille.

Time to Reach Full Enteral Feeding and Its Predictors among Very Low Birth Weight Neonates Admitted in the Neonatal Intensive Care Unit: A Follow-Up Cohort Study

Background

Feeding is crucial for very low birth weight neonates to grow and develop properly. This study aims to determine the time to achieve full enteral feeding and predictors among neonates admitted at Felege Hiwot Comprehensive Specialized Hospital.

Methods

An institutional retrospective follow-up study design was conducted among 332 very low birth weight neonates from July 1, 2018, to June 30, 2021. Samples were selected through a computer-generated simple random sampling method, and the data were entered into Epi data version 4.6 and then exported to STATA version 16 for analysis. Kaplan-Meier with the log-rank test was used to test for the presence of difference in survival among predictor variables. Model goodness of fit and assumptions were checked by the Cox-Snell residual and the global test, respectively. Variables with p value <0.25 in the bi-variable analysis were fitted to the multivariable Cox-proportional hazard model. Finally, the adjusted hazard ratio (AHR) with 95% CI was computed, and variables with a p value less than 0.05 in the multivariable Cox regression analysis were considered significant predictors of time to reach full enteral feeding.

Results

A total of 332 neonates were followed for 2,132 person days of risk time and 167 (50.3%) of very low birth weight neonates started full enteral feeding. The overall incidence rate of full enteral feeding was 7.8 per 100 person day observations. The median survival time was 7 days. Very low birth weight neonates delivered from pregnancy-induced hypertension-free mothers (AHR: 2.1; 95% CI: 1.12, 3.94), gestational age of ≥33 weeks (AHR: 5,; 95% CI: 2.29, 11.13), kangaroo mother care initiated (AHR: 1.4; 95% CI: 1.01, 2.00), avoiding prefeed residual aspiration (AHR: 1.42; 95% CI: 1.002-2.03), and early enteral feeding (AHR: 1.5; 95% CI: 1.03, 2.35) were significant predictors of full enteral feeding.

Conclusions

According to this study, the time to achieve full enteral feeding was relatively short. Therefore, healthcare professionals should emphasize achieving full enteral feeding and address hindering factors to save the lives of VLBW neonates.

Kangaroo Mother Care in Term and Late Preterm Neonates: A Systematic Review

This systematic review aims to investigate the efficacy of kangaroo mother care (KMC) in term and late-preterm babies. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, seven studies were analyzed, which covered a wide range of outcomes, from the post-vaccination serum bilirubin level and pain during the vaccination to the prevention of hypothermia and long-term neurodevelopmental outcomes. Results point out that KMC might come with some advantages such as the reduction of neonatal bilirubin levels, a painless and quicker vaccination process, and better prevention of hypothermia. Moreover, initial and lengthy KMC also plays a possible role in the better long-term brain development of low-birth-weight neonates. Furthermore, the limitation of smaller numbers of studies and variability in results remains to be solved. The next step is working to build stronger evidence and creating proper conditions for the implementation of KMC in future healthcare.

Skin to Skin Contact Correlated with Improved Production and Consumption of Mother's Own Milk

Background: Human milk diet, preferably mother's own milk (MOM) over donor milk (DM), is recommended for preterm infants. Expression of MOM in proximity to preterm infants, especially during or immediately after skin-to-skin contact (SSC), is associated with greater milk production. However, the correlation between SSC and MOM production during hospital admission in preterm infants has not yet been studied. Our study investigated the relationship between SSC and MOM production and consumption in preterm infants during the first postnatal month of life. Materials and Methods: This was a prospective cohort study. Mothers and their preterm infants born at <35 weeks by gestational age (GA) and eligible for SSC within the first 5 postnatal days were eligible for the study. Mothers were given a binder to document pumped breast milk volumes and SSC sessions. Pumped breast milk volumes, enteral feeding type and volume, and SSC duration and frequency were collected daily over the first 28 days of life, along with demographic, perinatal, and feeding data from electronic medical records (EMR). Results: Mean birth GA and weight were 30 ± 3 weeks and 1,443 ± 576 g, respectively. SSC duration was inversely correlated with GA and weight. The SSC duration was positively correlated with ingested MOM volume after correcting for birth GA. The SSC duration was predictive of increased volumes of pumped MOM. Conclusion: Our findings suggest that SSC duration is associated with improved MOM production and consumption. SSC can be a useful tool to increase MOM exposure and improve long-term health outcomes in preterm infants.

Effects of kangaroo mother care on feeding intolerance in preterm infants

OBJECTIVE

Feeding intolerance (FI) is a common condition in preterm infants because they have an immature gastrointestinal tract. There are studies on the effects of the position on gastric residual volume (GRV) in preterm infants. Kangaroo mother care (KMC) may be an instrument for reducing FI by providing an upright position to infants. Moreover, numerous studies conducted with this therapeutic position applied by putting an infant on the mother's chest have indicated its positive effects on the infant's weight gain, growth and development, and vital signs. Therefore, this study aimed to reveal the impact of KMC on FI in preterm infants.

METHODS

The population of the study, designed as a randomized trial, consisted of 168 preterm infants [KMC: 84, Standart Care (SC): 84] hospitalized in the neonatal intensive care unit of a university hospital between June and November 2020. Infants were randomly selected and divided into two groups. After the vital signs of the infants in both groups became stable, the infants were fed in the same position. KMC was applied to the infants in the intervention group for 1 h by preparing a suitable environment after feeding. Infants in the SC group were placed in the prone position after feeding. The GRVs of the infants in both groups were recorded on the Infant Follow-up Form before the next feeding.

RESULTS

No statistically significant difference was detected between the groups upon comparing them in terms of demographic and clinical characteristics. The body temperatures and O2 saturations of the participants in the KMC group were statistically significantly higher, and their respiratory and heart rates were lower than the SC group. The transition time to full enteral feeding was statistically significantly shorter, and FI was experienced significantly less in the KMC group infants than in the SC group (p < 0.05). There was no statistically significant difference between the groups in terms of the infants' weight gain and length of hospital stay (p > 0.05).

CONCLUSION

The present study demonstrated that KMC had a positive impact on FI in preterm infants. KMC is not only a safe care model providing the earliest contact between parents and infants but also a practice whose positive effect on the functioning of the digestive system in preterm infants we can use.

Skin-to-skin SDF positioning: The key to intersubjective intimacy between mother and very preterm newborn-A pilot matched-pair case-control study

Background

Skin-to-skin contact (SSC) has been widely studied in NICU and several meta-analyses have looked at its benefits, for both the baby and the parent. However, very few studies have investigated SSC' benefits for communication, in particular in the very-preterm newborn immediately after birth.

Aims

To investigate the immediate benefits of Supported Diagonal Flexion (SDF) positioning during SSC on the quality of mother-very-preterm newborn communication and to examine the coordination of the timing of communicative behaviors, just a few days after birth.

Subjects and study design

Monocentric prospective matched-pair case-control study. Thirty-four mothers and their very preterm infants (27 to 31 + 6 weeks GA, mean age at birth: 30 weeks GA) were assigned to one of the two SSC positioning, either the Vertical Control positioning (n = 17) or the SDF Intervention positioning (n = 17). Mother and newborn were filmed during the first 5 min of their first SSC.

Outcome measures

Infants' states of consciousness according to the Assessment of Preterm Infants' Behavior scale (APIB). Onset and duration of newborns' and mothers' vocalizations and their temporal proximity within a 1-s time-window.

Results

In comparison with the Vertical group, very preterm newborns in the SDF Intervention Group spent less time in a drowsy state and more in deep sleep. At 3.5 days of life, newborns' vocal production in SSC did not differ significantly between the two groups. Mothers offered a denser vocal envelope in the SDF group than in the Vertical group and their vocalizations were on average significantly longer. Moreover, in a one-second time-frame, temporal proximity of mother-very preterm newborn behaviors was greater in the SDF Intervention Group.

Conclusion

Although conducted on a limited number of dyads, our study shows that SDF positioning fosters mother-very preterm newborn intimate encounter during the very first skin to skin contact after delivery. Our pioneer data sheds light on the way a mother and her very preterm vocally meet, and constitutes a pilot step in the exploration of innate intersubjectivity in the context of very preterm birth.

The role of skin-to-skin contact in exclusive breastfeeding: a cohort study

OBJETIVE

To understand the role of exposure to skin-to-skin contact and its minimum duration in determining exclusive breastfeeding at hospital discharge in infants weighing up to 1,800g at birth.

METHODS

A multicenter cohort study was carried out in five Brazilian neonatal units. Infants weighing ≤ 1,800g at birth were eligible. Skin-to-skin contact time was recorded by the health care team and parents on an individual chart. Maternal and infant data was obtained from maternal questionnaires and medical records. The Classification Tree, a machine learning method, was used for data analysis; the tree growth algorithm, using statistical tests, partitions the dataset into mutually exclusive subsets that best describe the response variable and calculates appropriate cut-off points for continuous variables, thus generating an efficient explanatory model for the outcome under study.

RESULTS

A total of 388 infants participated in the study, with a median of 31.6 (IQR = 29–31.8) weeks of gestation age and birth weight of 1,429g (IQR = 1,202–1,610). The exclusive breastfeeding rate at discharge was 61.6%. For infant’s weighting between 1,125g and 1,655g, exposed to skin-to-skin contact was strongly associated with exclusive breastfeeding. Moreover, infants who made an average > 149.6 min/day of skin-to-skin contact had higher chances in this outcome (74% versus 46%). In this group, those who received a severity score (SNAPPE-II) equal to zero increased their chances of breastfeeding (83% versus 63%).

CONCLUSION

Skin-to-skin contact proved to be of great relevance in maintaining exclusive breastfeeding at hospital discharge for preterm infants weighing 1,125g–1,655g at birth, especially in those with lower severity scores.

Effects of skin-to-skin care on electrical activity of the diaphragm in preterm infants during neurally adjusted ventilatory assist

BACKGROUND

Skin-to-skin care (SSC) reduces neonatal mortality and morbidity and is widely implemented in the neonatal intensive care unit. However, changes in respiratory effort during SSC in ventilated preterm infants remain unclear.

AIMS

To evaluate the effect of SSC on electrical activity of the diaphragm (Edi) and vital signs in premature infants who are intubated and under neurally adjusted ventilatory assist ventilation.

STUDY DESIGN

We performed an observational cross-over study. Data were measured in three periods: before (pre-SSC period), during (SSC period), and after (post-SSC period) SSC. Stable 30-min data in each period were extracted.

SUBJECTS

Thirty-four SSC procedures were performed in 14 preterm infants with a median gestational age of 25.3 weeks (interquartile range, 24, 26.4) and a birth weight of 659 g (566, 694). The median postnatal age was 41 days (31, 53) at the study with a median postmenstrual age of 31.3 weeks (30.4, 32.5).

OUTCOME MEASURES

Median values of Edi peak, Edi minimum, respiratory rate, SpO₂, and heart rate were measured in each condition. The Kruskal-Wallis test with Bonferroni multiple comparisons was used to compare each parameter in each period.

RESULTS

Median Edi peak and Edi minimum values were significantly lower during SSC compared with pre- and post-SSC, without any change in respiratory rate, SpO₂, or heart rate.

CONCLUSIONS

Respiratory efforts as evaluated by Edi are significantly reduced during SSC in ventilated preterm infants.
