Kangaroo care improves post-extubation cardiorespiratory parameters in infants after open heart surgery

Simulation Training to Increase Holding of Fragile Infants in Cardiac Intensive Care Units

BACKGROUND

Promoting bonding and neurodevelopmental care is an important element in the cardiovascular intensive care unit (CICU); however, holding of infants by family members is inconsistently practiced.

OBJECTIVES

This quality improvement study aimed to safely increase the holding of medically complex infants in the CICU by developing a holding guideline and offering simulation-based staff education.

METHODS

Using consensus methodology and high-fidelity simulation, an expert work group created a holding guideline and training to increase staff confidence and competence in holding critically ill infants in the CICU. The effectiveness of the intervention was tested via a postintervention survey used to assess participants' confidence in and comfort with holding critically ill infants and elicit suggestions for further support. Participants who engaged with the mannequin were surveyed to assess the validity of the simulation trainer.

RESULTS

After the intervention, participants (N = 130) reported increased confidence with infant holding (76%) and greater confidence in preparing families to hold their infants. Participants (95%) strongly agreed that the simulation enabled realistic, safe practice in holding a medically complex infant with catheters and tubes. More years of experience and engagement with the simulation trainer were associated with increased posttraining confidence. Participants cited increased resources, practice, and adherence monitoring as key supports for infant holding.

CONCLUSIONS

Expert group consensus with high-fidelity simulation training is a feasible, safe, and reliable method for teaching higher risk skills and guiding protocol development.

Parental holding of infants improves haemodynamics in the cardiac ICU

We performed a single-centre, retrospective study to assess physiologic changes of infants in the cardiac ICU while being held by their parent. Continuous data streaming of vital signs were collected for infants included in the study from January 2021 to March 2022. Demographic and clinical characteristics were collected from the electronic medical record. The physiologic streaming data were analysed using mixed-effects models to account for repeated measures and quantify the effect of parental holding. Comparison analysis was also performed controlling for intubation, pre-operative versus post-operative status, and whether the holding was skin-to-skin or not. Ninety-five patients with complete physiologic data were included in the study. There were no immediate adverse events associated with holding. Heart rate decreased during the response time compared to its baseline value (p = 0.01), and this decrease was more pronounced for the non-intubated and pre-operative patients. The near-infrared spectroscopy-based venous saturation increased overall (p = 0.02) in patients while being held. We conclude that parental holding of infants in the cardiac ICU can be safely accomplished, and the haemodynamic and oximetric profile during the holding is favourable compared to the infants' baseline prior to holding.

Optimizing Neurodevelopmental Outcomes in Neonates With Congenital Heart Disease

Neurodevelopmental impairment is a common and important long-term morbidity among infants with congenital heart disease (CHD). More than half of those with complex CHD will demonstrate some form of neurodevelopmental, neurocognitive, and/or psychosocial dysfunction requiring specialized care and impacting long-term quality of life. Preventing brain injury and treating long-term neurologic sequelae in this high-risk clinical population is imperative for improving neurodevelopmental and psychosocial outcomes. Thus, cardiac neurodevelopmental care is now at the forefront of clinical and research efforts. Initial research primarily focused on neurocritical care and operative strategies to mitigate brain injury. As the field has evolved, investigations have shifted to understanding the prenatal, genetic, and environmental contributions to impaired neurodevelopment. This article summarizes the recent literature detailing the brain abnormalities affecting neurodevelopment in children with CHD, the impact of genetics on neurodevelopmental outcomes, and the best practices for neonatal neurocritical care, focusing on developmental care and parental support as new areas of importance. A framework is also provided for the infrastructure and resources needed to support CHD families across the continuum of care settings.

Developmental Care Practice and Documentation Variability in the Cardiac ICU

OBJECTIVES

Describe variability in developmental care practices, as documented in the electronic health record, for infants undergoing congenital heart surgery.

DESIGN

Multicenter, retrospective, cohort study.

SETTING

Six pediatric cardiac centers.

PATIENTS

One hundred eighty-two infants undergoing one of three index operations: Norwood palliation, aortic arch reconstruction with ventricular septal defect closure, or arterial switch.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Core domains of developmental care encompassing pain assessment, feeding, infant holding, caregiver involvement, therapy, and psychosocial services were reviewed. Practices varied across individuals, institutions, and the hospital stay. At five of six sites, greater than 90% of individuals had physical or occupational therapy services as part of their care, but the day of first evaluation ranged from day of admission to postoperative day 28. Similar patterns were seen in feeding team and social work involvement. Consistent documentation of developmental care was dependent on the domain and site. Of the total days reviewed (n = 1,192), pain scores were documented in 95%. In those same days, documentation of whether or not a patient was out of the crib to be held varied by site from 11% to 93%. Type of oral feeding, breast versus bottle, was documented on the day prior to discharge 48% of the time.

CONCLUSIONS

There are significant, quantifiable variations in documented developmental care practices at both the individual and site level. More reliable documentation of developmental care practices is required to associate these variables with later outcomes and investigate disparities in individualized developmental care practices.

Individualized Family-Centered Developmental Care for Infants With Congenital Heart Disease in the Intensive Care Unit

BACKGROUND

Individualized family-centered developmental care (IFDC) is considered the standard of care for premature/medically fragile newborns and their families in intensive care units (ICUs). Such care for infants with congenital heart disease (CHD) varies.

OBJECTIVE

The Consortium for Congenital Cardiac Care- Measurement of Nursing Practice (C4-MNP) was surveyed to determine the state of IFDC for infants younger than 6 months with CHD in ICUs.

METHODS

An electronic survey was disseminated to 1 nurse at each participating center. The survey included questions on IFDC-related nursing practice, organized in 4 sections: demographics, nursing practice, interdisciplinary practice, and parent support. Data were summarized by using descriptive statistics. Differences in IFDC practices and IFDC-related education were assessed, and practices were compared across 3 clinical scenarios of varying infant acuity by using the χ2 test.

RESULTS

The response rate was 66% (25 centers). Most respondents (72%) did not have IFDC guidelines; 63% incorporated IFDC interventions and 67% documented IFDC practices. Only 29% reported that their ICU had a neurodevelopmental team. Significant differences were reported across the 3 clinical scenarios for 11 of 14 IFDC practices. Skin-to-skin holding was provided least often across all levels of acuity. Nurse education related to IFDC was associated with more use of IFDC (P < .05).

CONCLUSION

Practices related to IFDC vary among ICUs. Opportunities exist to develop IFDC guidelines for infants with CHD to inform clinical practice and nurse education. Next steps include convening a C4-MNP group to develop guidelines and implement IFDC initiatives for collaborative evaluation.

Comfort-holding in critically ill children: a scoping review

PURPOSE

To understand and summarize the breadth of knowledge on comfort-holding in pediatric intensive care units (PICUs).

SOURCES

This scoping review was conducted using PRISMA methodology. A literature search was conducted in MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane CENTRAL Register of Controlled Trials. Search strategies were developed with a medical librarian and revised through a peer review of electronic search strategies. All databases were searched from inception to 14 April 2020. Only full-text articles available in English were included. All identified articles were reviewed independently and in duplicate using predetermined criteria. All study designs were eligible if they reported on comfort-holding in a PICU. Data were extracted independently and in duplicate.

PRINCIPAL FINDINGS

Of 13,326 studies identified, 13 were included. Comfort-holding was studied in the context of end-of-life care, developmental care, mobilization, and as a unique intervention. Comfort-holding is common during end-of-life care with 77.8% of children held, but rare during acute management (51% of children < three years, < 5% of children ≥ three years). Commonly reported outcomes included child outcomes (e.g., physiologic measurements), safety outcomes (e.g., accidental line removal), parent outcomes (e.g., psychological symptoms), and frequency of holding.

CONCLUSION

There is a paucity of literature on comfort-holding in PICUs. This scoping review identifies significant gaps in the literature, including assessment of child-based outcomes of comfort-holding or safety assessment of comfort-holding, and highlights core outcomes to consider in future evaluations of this intervention including child-based outcomes, parent-based outcomes, and safety of the intervention.

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.

Skin-to-Skin Care is Associated with Reduced Stress, Anxiety, and Salivary Cortisol and Improved Attachment for Mothers of Infants With Critical Congenital Heart Disease

OBJECTIVE

To estimate the effect of skin-to-skin care (SSC) on biobehavioral measures of stress (anxiety and salivary cortisol) and attachment (attachment scores and salivary oxytocin) of mothers before and after their infants' neonatal cardiac surgery.

DESIGN

A prospective interventional, baseline response-paired pilot study.

SETTING

Cardiac center of a large, metropolitan, freestanding children's hospital.

PARTICIPANTS

Thirty women whose infants were hospitalized for neonatal cardiac surgery.

METHODS

Participants acted as their own controls before, during, and after SSC at two time points: once before and once after surgery. We measured the stress response of mothers, as indicated by self-reported scores of anxiety and maternal salivary cortisol, and maternal-infant attachment, as indicated by self-reported scores and maternal salivary oxytocin.

RESULTS

Significant reductions in self-reported scores of anxiety and salivary cortisol were found as a result of SSC at each time point, as well as increased self-reported attachment. No significant differences were found in oxytocin.

CONCLUSION

Our findings provide initial evidence of the benefits of SSC as a nurse-led intervention to support maternal attachment and reduce physiologic and psychological stress responses in mothers of infants with critical congenital heart disease before and after neonatal cardiac surgery.

Skin-to-Skin Care Is a Safe and Effective Comfort Measure for Infants Before and After Neonatal Cardiac Surgery

OBJECTIVES

To determine the effect of skin-to-skin care on stress, pain, behavioral organization, and physiologic stability of infants with critical congenital heart disease before and after neonatal cardiac surgery.

DESIGN

A baseline response-paired design was used, with infants acting as their own controls before, during, and after skin-to-skin care at two distinct time points: once in the preoperative period (T1) and once in the postoperative period (T2).

SETTING

Cardiac ICU and step-down unit in a large metropolitan freestanding children's hospital.

SUBJECTS

Convenience sample of 30 infants admitted preoperatively for critical congenital heart disease.

INTERVENTIONS

Eligible infants were placed into skin-to-skin care for 1 hour with their biological mothers once each at T1 and T2.

MEASUREMENTS AND MAIN RESULTS

Measurements of stress (salivary cortisol), pain and behavior state (COMFORT scale), and physiologic stability (vital signs) were assessed immediately before skin-to-skin care, 30 minutes into skin-to-skin care, and 30 minutes after skin-to-skin care ended.At both T1 and T2, infant pain scores were significantly decreased (p < 0.0001) and infants moved into a calmer behavior state (p < 0.0001) during skin-to-skin care as compared to baseline. At T1, infants also had significantly reduced heart rate (p = 0.002) and respiratory rate (p < 0.0001) and increased systolic blood pressure (p = 0.033) during skin-to-skin care. At both T1 and T2, infant cortisol remained stable and unchanged from pre-skin-to-skin care to during skin-to-skin care (p = 0.096 and p = 0.356, respectively), and significantly increased from during skin-to-skin care to post-skin-to-skin care (p = 0.001 and p = 0.023, respectively). Exploratory analysis revealed differences in cortisol reactivity for infants with higher baseline cortisol (> 0.3 μg/dL) versus lower (≤ 0.3 μg/dL) prior to skin-to-skin care. Infants with higher baseline cortisol at T2 experienced significantly reduced cortisol during skin-to-skin care (p = 0.025). No significant differences in demographics or baseline variables were found between infants in either group.

CONCLUSIONS

Skin-to-skin care is a low-cost, low-risk intervention that promotes comfort and supports physiologic stability in infants before and after neonatal cardiac surgery.

Kangaroo Care for Hospitalized Infants with Congenital Heart Disease

BACKGROUND

Kangaroo care (KC), or skin-to-skin care, occurs when an infant is dressed in a diaper and held to a parent's bare chest. This form of holding has been shown to have many benefits for hospitalized infants and has been shown to be a safe and feasible intervention to support infants with congenital heart disease. Despite known benefits, KC was not implemented routinely and consistently in our cardiac center for infants with congenital heart disease. The purpose of this project was to support use of KC as a nursing intervention for hospitalized infants with congenital heart disease and their parents.

METHODS

A KC quality improvement committee formed to develop strategies to increase frequency of KC, including the creation of a new nursing policy and procedure on KC for infants, adaptation of the electronic health record to facilitate KC documentation, education, and supporting translation of KC into practice through the cardiac center's first Kangaroo-A-Thon.

RESULTS

Twenty-six nurses initiated KC 43 times with 14 patients over the 8-week period for the Kangaroo-A-Thon. No adverse events were reported as a result of infants being held by their parents in KC.

CONCLUSION

Our local initiative provided preliminary evidence that KC can be safely integrated into standard care for hospitalized infants with congenital heart disease. Formal standards and procedures, along with creative initiatives such as a Kangaroo-A-Thon, can be a first step toward fostering the translation of KC into practice.

Supporting Optimal Neurodevelopmental Outcomes in Infants and Children With Congenital Heart Disease

Improved survival has led to increased recognition of developmental delays in infants and children with congenital heart disease. Risk factors for developmental delays in congenital heart disease survivors may not be modifiable; therefore, it is important that lifesaving, high-technology critical care interventions be combined with nursing interventions that are also developmentally supportive. Implementing developmental care in a pediatric cardiac intensive care unit requires change implementation strategies and widespread support from all levels of health care professionals. This manuscript reviews developmentally supportive interventions such as massage, developmentally supportive positioning, kangaroo care, cue-based feeding, effective pain/anxiety management, and procedural preparation and identifies strategies to implement developmentally supportive interventions in the care of infants and children with congenital heart disease. Improving developmental support for these infants and children at high risk for developmental delay may improve their outcomes and help promote family-centered care.

Autonomic Nervous System Function After a Skin-to-Skin Contact Intervention in Infants With Congenital Heart Disease

BACKGROUND

Infants with complex congenital heart disease (CCHD) demonstrate impaired autonomic nervous system (ANS) regulation, which may contribute to commonly observed impairments in feeding, growth, and development. Close mother-infant physical contact improves ANS function in other high-risk infant populations.

OBJECTIVE

Our purposes were to examine feasibility of a 2-week daily skin-to-skin contact (SSC) intervention and to describe change in ANS function in response to the intervention.

METHODS

Feasibility was assessed by recruitment and retention rates, safety, and acceptability. Autonomic nervous system function was measured with linear and nonlinear measures of heart rate variability (HRV) during a feeding before the 14-day SSC intervention and 3 times during a 4-week follow-up.

RESULTS

Recruitment rate was 72%; retention rate was 55.5%. Mothers were universally positive about SSC. Ten mothers and infants completed a daily mean of 77.05 minutes of SSC during the 14-day intervention with no adverse events. Baseline high-frequency HRV, reactivity to challenge, and recovery after challenge improved during the 6-week study. Nonlinear measures demonstrated abnormally high sympathetic activity, especially after feeding, in most infants.

CONCLUSIONS

Skin-to-skin contact is feasible in infants with CCHD. Linear measures of HRV suggested improvements in ANS function with this intervention. This article is one of the first to describe nonlinear HRV measures in infants with CCHD. Additional research is needed to identify variations in linear and nonlinear effects based on specific cardiac conditions and with varying intervention doses and timing. This low-cost, low-risk intervention has the potential to improve outcomes in infants with CCHD.

Developmentally Supportive Care in Congenital Heart Disease: A Concept Analysis

THEORETICAL PRINCIPLES

Improved survival of infants and children with congenital heart disease experience has led to recognition that up to half of congenital heart disease survivors also experience developmental delay. Developmentally supportive care is a care model shown in Neonatal Intensive Care Units to be associated with improved outcomes, but developmentally supportive practices with premature infants may not be equally effective in the cardiac population that includes all ages.

PHENOMENA ADDRESSED

The purpose of this paper is to present a concept analysis using the Walker and Avant method in order to identify and define characteristics of developmentally supportive care as it may be applied to the population of neonates, infants, and children with congenital heart disease. A theoretical definition of developmentally supportive care is presented.

RESEARCH LINKAGES

This concept analysis will provide nurses and allied health professionals with a theoretical basis to implement high quality, family-centered care that meets individual developmental needs in a population at high risk for developmental sequelae. Nursing implications for developmentally supportive care as it applies to infants and children with heart disease are discussed.

Skin-to-skin care for procedural pain in neonates

BACKGROUND

Skin-to-skin care (SSC), often referred to as 'kangaroo care' (KC) due to its similarity with marsupial behaviour of ventral maternal-infant contact, is one non-pharmacological intervention for pain control in infants.

OBJECTIVES

The primary objectives were to determine the effect of SSC alone on pain from medical or nursing procedures in neonates compared to no intervention, sucrose or other analgesics, or additions to simple SSC such as rocking; and to determine the effects of the amount of SSC (duration in minutes), method of administration (e.g. who provided the SSC) of SSC in reducing pain from medical or nursing procedures in neonatesThe secondary objectives were to determine the safety of SSC care for relieving procedural pain in infants; and to compare the SSC effect in different postmenstrual age subgroups of infants.

SEARCH METHODS

For this update, we used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 1); MEDLINE via PubMed (1966 to 25 February 2016); Embase (1980 to 25 February 2016); and CINAHL (1982 to 25 February 2016). We also searched clinical trials' databases, conference proceedings, and the reference lists of retrieved articles for randomized controlled trials and quasi-randomized trials.

SELECTION CRITERIA

Studies with randomisation or quasi-randomisation, double- or single-blinded, involving term infants (≥ 37 completed weeks' postmenstrual age (PMA) to a maximum of 44 weeks' PMA and preterm infants (< 37 completed weeks PMA) receiving SSC for painful procedures conducted by healthcare professionals.

DATA COLLECTION AND ANALYSIS

The main outcome measures were physiological or behavioural pain indicators and composite pain scores. A mean difference (MD) with 95% confidence interval (CI) using a fixed-effect model was reported for continuous outcome measures. We included variations on type of tissue-damaging procedure, provider of care, and duration of SSC.

MAIN RESULTS

Twenty-five studies (n = 2001 infants) were included. Nineteen studies (n = 1065) used heel lance as the painful procedure, one study combined venepuncture and heel stick (n = 50), three used intramuscular injection (n = 776), one used 'vaccination' (n = 60), and one used tape removal (n = 50). The studies were generally strong and had low or uncertain risk of bias. Blinding of the intervention was not possible, making them subject to high risk, depending on the method of scoring outcomes.Seventeen studies (n = 810) compared SSC to a no-treatment control. Although 15 studies measured heart rate during painful procedures, data from only five studies (n = 161) could be combined for a mean difference (MD) of -10.78 beats per minute (95% CI -13.63 to -7.93) favouring SSC. Meta-analysis of four studies (n = 120) showed no difference in heart rate following the painful procedure (MD 0.08, 95% CI -4.39 to 4.55). Two studies (n = 38) reported heart rate variability with no significant differences. Two studies (n = 101) in a meta-analysis on oxygen saturation at 30 and 60 seconds following the painful procedure did not show a difference. Duration of crying meta-analysis was performed on four studies (n = 133): two (n = 33) investigated response to heel lance (MD = -34.16, 95% CI -42.86 to -25.45), and two (n = 100) following IM injection (MD = -8.83, 95% CI -14.63 to -3.02), favouring SSC. Five studies, one consisting of two substudies (n = 267), used the Premature Infant Pain Profile (PIPP) as a primary outcome, which favoured SCC at 30 seconds (MD -3.21, 95% CI -3.94 to -2.47), at 60 seconds (3 studies; n = 156) (MD -1.64, 95% CI -2.86 to -0.43), and at 90 seconds (n = 156) (MD -1.28, 95% CI -2.53 to -0.04); but at 120 seconds there was no difference (n = 156) (MD 0.07, 95% CI -1.11 to 1.25). No studies on return of heart rate to baseline level, cortisol levels, and facial actions could be combined for meta-analysis findings.Eight studies compared SSC to another intervention with or without a no-treatment control. Two cross-over studies (n = 80) compared mother versus other provider (father, another female) on PIPP scores at 30, 60, 90, and 120 seconds with no significant difference. When SSC was compared to other interventions, there were not enough similar studies to pool results in an analysis. One study compared SSC (n = 640) with and without dextrose and found that the combination was most effective and that SSC alone was more effective than dextrose alone. Similarly, in another study SSC was more effective than oral glucose for heart rate (n = 95). SSC either in combination with breastfeeding or alone was favoured over a no-treatment control, but not different to breastfeeding. One study compared SSC alone and in combination with both sucrose and breastfeeding on heart rate (HR), NIPS scores, and crying time (n = 127). The combinations were more effective than SSC alone for NIPS and crying. Expressed breast milk was compared to SSC in one study (n = 50) and found both equally effective on PIPP scores. There were not enough participants with similar outcomes and painful procedures to compare age groups or duration of SSC. No adverse events were reported in any of the studies.

AUTHORS' CONCLUSIONS

SSC appears to be effective as measured by composite pain indicators with both physiological and behavioural indicators and, independently, using heart rate and crying time; and safe for a single painful procedure. Purely behavioural indicators tended to favour SSC but with facial actions there is greater possibility of observers not being blinded. Physiological indicators were mixed although the common measure of heart rate favoured SSC. Two studies compared mother-providers to others, with non-significant results. There was more heterogeneity in the studies with behavioural or composite outcomes. There is a need for replication studies that use similar, clearly defined outcomes. Studies examining optimal duration of SSC, gestational age groups, repeated use, and long-term effects of SSC are needed. Of interest would be to study synergistic effects of SSC with other interventions.

A Case Study of Infant Physiologic Response to Skin-to-Skin Contact After Surgery for Complex Congenital Heart Disease

BACKGROUND

Infants with complex congenital heart disease requiring surgical intervention within the first days or weeks of life may be the most seriously ill infants needing intensive nursing and medical care. Skin-to-skin contact (SSC) is well accepted and practiced as a positive therapeutic intervention in premature infants but is not routinely offered to infants in cardiac intensive care units. The physiologic effects of SSC in the congenital heart disease population must be examined before recommending incorporation of SSC into standard care routines.

OBJECTIVE

The purpose of this case study was to describe the physiologic response to a single session of SSC in an 18-day-old infant with hypoplastic left heart syndrome.

METHODS

Repeated measures of heart rate, respiratory rate, oxygen saturation, blood pressure, and temperature were recorded 30 minutes before SSC, during SSC (including interruptions for bottle and breast feedings), and 10 minutes after SSC was completed.

RESULTS

All physiologic parameters were clinically acceptable throughout the 135-minute observation.

CONCLUSION

This case study provides beginning evidence that SSC is safe in full-term infants after surgery for complex congenital heart disease. Further research with a larger sample is needed to examine the effects of SSC on infant physiology before surgery and earlier in the postoperative time period as well as on additional outcomes such as length of stay, maternal-infant interaction, and neurodevelopment.

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

BACKGROUND

Kangaroo mother care (KMC) has been widely used to improve the care of preterms and low birth weight infants. However, very little is known about cerebral hemodynamics responses in preterm infants during KMC intervention. The aim of this study is to evaluate the changes of cerebral blood flow (CBF) in middle cerebral artery, before and after a 30 minute application of KMC in stable preterm infants.

METHODS

It is a prospective, pre-post test without a control group study. CBF flow paremeters were measured with Doppler ultrasonography in one middle cerebral artery. Sixty preterm stable infants were assessed before and after 30 min KMC. CBF indices were assessed in different positions before KMC, forty neonates in supine position and 20 in vertical suspension (baby is held vertically away from the skin of his mother). Other dependent variables heart rate and mean arterial blood pressure and Spo2 were also studied before and after KMC.

RESULTS

The mean gestational age of the infants was (32 ± 2 weeks), and mean birth weight was (2080 ± 270 gm). Comparing CBF indices (Pulsatility index and Resistive index) before and after KMC has shown a significant decrease in both Pulsatility index (PI) and Resistive index (RI) after 30 min. KMC, the mean values were (2.0 ± 0.43 vs 1.68 ± 0.33 & 0.81 ± 0.05 vs 0.76 ± 0.06 respectively P < 0.05*) with mean difference (0.32 & 95% CI 0.042-0.41 & 0.05 & 95% CI 0.04 to 0.06 respectively P < 0.05*) and increase in end diastolic velocity & mean velocity 30 min of KMC (10.97 ± 4.63 vs. 15.39 ± 5.66 P < 0.05*& 25.66 ± 10.74 vs. 32.86 ± 11.47 P < 0.05* ) with mean difference (- 4.42 & 95% CI -5.67 to -3.18 and -7.21 & 95% CI - 9.41 to 5.00 respectively). These changes indicate improvement in CBF. No correlation has been found between CBF parameters and studied vital signs or SpO2.

CONCLUSION

Kangaroo mother care improves cerebral blood flow, thus it might influence the structure and promote development of the premature infant's brain.

Skin-to-skin care for procedural pain in neonates

BACKGROUND

Skin-to-skin care (SSC), otherwise known as Kangaroo Care (KC) due to its similarity with marsupial behaviour of ventral maternal-infant contact, is one non-pharmacological intervention for pain control in infants.

OBJECTIVES

The primary objectives were to determine the effect of SSC alone on pain from medical or nursing procedures in neonates undergoing painful procedures compared to no intervention, sucrose or other analgesics, or additions to simple SSC such as rocking; and the effects of the amount of SSC (duration in minutes) and the method of administration (who provided the SSC, positioning of caregiver and neonate pair).The secondary objectives were to determine the incidence of untoward effects of SSC and to compare the SSC effect in different postmenstrual age subgroups of infants.

SEARCH METHODS

The standard methods of the Cochrane Neonatal Collaborative Review Group were used. Databases searched in August 2011: Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library); Evidence-Based Medicine Reviews; MEDLINE (1950 onwards); PubMed (1975 onwards); EMBASE (1974 onwards); CINAHL (1982 onwards); Web of Science (1980 onwards); LILACS database (1982 onwards); SCIELO database (1982 onwards); PsycInfo (1980 onwards); AMED (1985 onwards); Dissertation-Abstracts International (1980 onwards). Searches were conducted throughout September 2012.

SELECTION CRITERIA

Studies with randomisation or quasi-randomisation, double or single-blinded, involving term infants (> 37 completed weeks postmenstrual age (PMA)) to a maximum of 44 weeks PMA and preterm infants (< 37 completed weeks PMA) receiving SSC for painful procedures conducted by doctors, nurses, or other healthcare professionals.

DATA COLLECTION AND ANALYSIS

The main outcome measures were physiological or behavioural pain indicators and composite pain scores. A weighted mean difference (WMD) with 95% confidence interval (CI) using a fixed-effect model was reported for continuous outcome measures. We included variations on type of tissue-damaging procedure, provider of care, and duration of SSC.

MAIN RESULTS

Nineteen studies (n = 1594 infants) were included. Fifteen studies (n = 744) used heel lance as the painful procedure, one study combined venepuncture and heel stick (n = 50), two used intramuscular injection, and one used 'vaccination' (n = 80). The studies that were included were generally strong and free from bias.Eleven studies (n = 1363) compared SSC alone to a no-treatment control. Although 11 studies measured heart rate during painful procedures, data from only four studies (n = 121) could be combined to give a mean difference (MD) of 0.35 beats per minute (95% CI -6.01 to 6.71). Three other studies that were not included in meta-analyses also reported no difference in heart rate after the painful procedure. Two studies reported heart rate variability outcomes and found no significant differences. Five studies used the Premature Infant Pain Profile (PIPP) as a primary outcome, which favoured SCC at 30 seconds (n = 268) (MD -3.21, 95% CI -3.94 to -2.48), 60 seconds (n = 164) (MD -1.85, 95% CI -3.03 to -0.68), and 90 seconds (n = 163) (MD -1.34, 95% CI -2.56 to -0.13), but at 120 seconds (n = 157) there was no difference. No studies provided findings on return of heart rate to baseline level, oxygen saturation, cortisol levels, duration of crying, and facial actions that could be combined for analysis.Eight studies compared SSC to another intervention with or without a no-treatment control. Two cross-over studies (n = 80) compared mother versus other provider on PIPP scores at 30, 60, 90, and 120 seconds with no significant difference. When SSC was compared to other interventions, there were not enough similar studies to pool results in an analysis. One study compared SSC with and without dextrose and found that the combination was most effective and that SSC alone was more effective than dextrose alone. Similarly, in another study SSC was more effective than oral glucose for heart rate but not oxygen saturation. SSC either in combination with breastfeeding or alone was favoured over a no-treatment control, but was not different to breastfeeding. There were not enough participants with similar outcomes and painful procedures to compare age groups or duration of SSC. No adverse events were reported in any of the studies.

AUTHORS' CONCLUSIONS

SSC appears to be effective, as measured by composite pain indicators and including both physiological and behavioural indicators, and safe for a single painful procedure such as a heel lance. Purely behavioural indicators tended to favour SSC but there remains questionable bias regarding behavioural indicators. Physiological indicators were typically not different between conditions. Only two studies compared mother providers to others, with non-significant results. There was more heterogeneity in the studies with behavioural or composite outcomes. There is a need for replication studies that use similar, clearly defined outcomes. New studies examining optimal duration of SSC, gestational age groups, repeated use, and long-term effects of SSC are needed.

Nonpharmacological management of pain during common needle puncture procedures in infants: current research evidence and practical considerations

All infants undergo painful procedures involving skin puncture as part of routine medical care. Pain from needle puncture procedures is suboptimally managed. Numerous nonpharmacologic interventions are available for these painful procedures, including swaddling, holding, skin-to-skin care, pacifier, sweet-tasting solutions, and breast-feeding. Adoption of nonpharmacologic pain-relieving interventions into routine clinical practice is feasible and should be a standard of care in the delivery of quality health care for infants. This review summarizes current knowledge about the epidemiology of pain from common needle puncture procedures in infants, the effectiveness of nonpharmacologic interventions, implementation considerations, and unanswered questions for future research.

Meta-analysis of physiological effects of skin-to-skin contact for newborns and mothers

BACKGROUND

Skin-to-skin care has been adopted all over the world, although physiological changes during or after it have not been evaluated very well. The purpose of the present study was therefore to investigate whether skin-to-skin contact for newborn babies and their mothers affects body temperature, heart rate and oxygen saturation of the babies.

METHODS

Studies investigating body temperature, heart rate and oxygen saturation of babies during and/or after skin-to-skin contact were systematically searched and reviewed. Meta-analyses to examine the effects and meta-regression analyses to investigate correlations between the effects and birthweight, duration of the care, environmental temperature, and resources of the setting, were conducted.

RESULTS

A total of 23 studies were included. Meta-analyses showed evidence of an increase in body temperature (weighted mean difference [WMD] 0.22 degrees C, P < 0.001) and a decrease in saturation of babies (WMD -0.60%; P= 0.01) during skin-to-skin care, compared with those before skin-to-skin care. Increase in body temperature was more evident in middle-low-income settings (WMD, 0.61 degrees C, P < 0.001) than high-income settings (WMD 0.20 degrees C, P < 0.001). Both the positive effect on body temperature and the negative effect on saturation were more marked in cold environments than where the environmental temperature was higher (WMD 0.18 degrees C, P < 0.001; WMD -0.82%, P= 0.02).

CONCLUSION

Skin-to-skin care is effective in increasing the body temperature of babies, especially where resources are limited and the environment is cold. Decreased oxygen saturation of the babies, however, warrants further prospective studies to confirm the findings.

Kangaroo Care modifies preterm infant heart rate variability in response to heel stick pain: pilot study

BACKGROUND

Heel stick is the most common painful procedure for preterm infants in neonatal intensive care units. Resultant pain causes adverse physiological effects in major organ systems. Kangaroo Care (KC), involving mother-infant skin-to-skin contact is a promising analgesic for infant pain; however, the effect of KC on the autonomic nervous system's response to pain is unknown.

AIM

To determine if KC results in improved balance in autonomic responses to heel stick pain than the standard method where infants remain in an incubator care (IC) for the heel stick.

STUDY DESIGN

A randomized cross-over trial.

SUBJECTS

Fourteen preterm infants, 30-32 weeks gestational age and less than 9 days postnatal age.

OUTCOME MEASURES

Infant behavioral state, heart rate, heart rate variability (HRV) indices including low frequency (LF) and high frequency (HF) power, and the LF/HF ratio measured over Baseline, Heel Warming, Heel Stick, and Recovery periods in KC and IC conditions.

RESULTS

HRV differences between KC and IC were that LF was higher in KC at Baseline (p<.01) and at Heel Stick (p<.001), and HF was higher in KC at Baseline than in the IC condition (p<.05). The LF/HF ratio had less fluctuation across the periods in KC than in IC condition and was significantly lower during Recovery in KC than in IC (p<.001).

CONCLUSIONS

Infants experienced better balance in response in KC than IC condition as shown by more autonomic stability during heel stick. KC may be helpful in mediating physiologic response to painful procedures in preterm infants.

Interação mãe-bebê pré-termo e mudança no estado de humor: comparação do Método Mãe-Canguru com visita na Unidade de Terapia Intensiva Neonatal

OBJETIVO: avaliar mudanças nos estados de humor de mães de bebês pré-termo em função do tipo de contato com o seu filho: Método Mãe-Canguru (MMC) e visita ao filho na incubadora da Unidade de Terapia Intensiva Neonatal. MÉTODOS: foi aplicada a Escala Analógica de Humor em 60 mães divididas em 2 grupos: mães que participam do Método Mãe-Canguru (GC) e mães que acompanharam o bebê na incubadora (GI). Os grupos foram pareados em função da idade das mães, número de gestações e tipo de parto. As mães foram avaliadas antes e depois de uma das visitas ao filho na incubadora ou sessão de MMC. RESULTADOS: as mães do GC melhoraram o humor, relatando: sentirem-se mais calmas, fortes, com idéias claras, ágeis, dinâmicas, satisfeitas, tranqüilas, perspicazes, relaxadas, atentas, competentes, alegres e amistosas. As mães do GI não apresentaram melhora no estado de humor em nenhum item, mas pioraram no item "sentindo-se desajeitada". CONCLUSÕES: o Método Mãe-Canguru mostrou-se eficaz na melhora nos estados de humor de mães de bebês pré-termo, contribuindo assim para a minimização dos efeitos negativos da internação neonatal.

Natural Parenting — Back to Basics in Infant Care

This review examines an age-old approach to parenting recently rediscovered in Western industrialized societies and known by names such as natural parenting, attachment parenting, and instinctive parenting. Its leading principle is utmost sensitivity to the child's innate emotional and physical needs, resulting in extended breastfeeding on demand, extensive infant carrying on the caregiver's body, and cosleeping of infant and parents. The described practices prevailed during the evolutionary history of the human species and reflect the natural, innate rearing style of the human species to which the human infant has biologically adapted over the course of evolution. An overview of research from diverse areas regarding psychological as well as physiological aspects of early care provides evidence for the beneficial effects of natural parenting. Cross-cultural and historical data is cited to reveal the widespread use of the investigated parenting style. It is concluded that the described approach to parenting provides the human infant with an ideal environment for optimal growth both psychologically and physiologically. It is yet to be determined how much departure from this prototype of optimal human parenting is possible without compromising infant and parental wellbeing. The review also invites a critical reevaluation of current Western childrearing practices.

Implications of Kangaroo Care for Growth and Development in Preterm Infants

OBJECTIVE

To review research on kangaroo care with implications for growth and development in preterm infants.

DATA SOURCES

Nursing, medical, and child development research literature was searched through PubMed through 2003 using the search terms kangaroo Care, skin-to-skin, growth/development, and premature infants.

STUDY SELECTION

Randomized controlled trials, pretest-posttest designs, and other comparative studies of kangaroo care were reviewed. Reports exploring parent perspectives were examined for attachment and parent-infant interaction findings. Theory and research regarding growth in preterm infants were explored.

DATA EXTRACTION

Research on topics of kangaroo care, skin-to-skin contact, preterm infant growth, preterm infant weight gain, and failure to thrive was evaluated.

DATA SYNTHESIS

Research on kangaroo care reports physiologic safety for preterm infants and increased attachment for parents. Attachment promotes nurturing behaviors that support growth and development. Weight gain as a benefit of kangaroo care remains in question.

CONCLUSIONS

Kangaroo care is safe for preterm infants and may have important benefits for growth and development. Suggestions are made for future research on effects of KC on preterm infants.

Emotion regulation and touch in infants: the role of cholecystokinin and opioids

Behavioral-pharmacological research in infant rats supports the role of cholecystokinin (CCK) and opioid peptides in mediating early learning of new associations with aspects of the nest and dam, such as maternal odor, milk, and contact. The current paper reviews research that examines the hypothesis that these neuropeptide systems are further involved in mediating emotion regulation in infants, thus playing a role in the emergence of stress-reactivity and other motivational systems. The beneficial effects of maternal proximity, handling, and touch on the development of emotion regulation have been demonstrated in both human and animal models. Interventions that promote tactile stimulation of the infant ("touch therapy") and infant-mother contact ("skin-to-skin contact" or "kangaroo care") have been shown to improve the infant's ability to self-regulate, and to moderate the effects of some risk factors. Theoretical perspectives and empirical findings regarding emotion regulation in infants are first discussed. This is followed by a review of work providing evidence in animal models (and suggestive evidence in humans) for the importance of CCK and opioid neuropeptides in affecting infant emotion regulation and the impact of touch-based interventions, in particular in the context of infant-mother attraction, contact, separation, and attachment.

Infant crying: nature, physiologic consequences, and select interventions

This article describes the nature of infant crying, the physiologic events and changes associated with it, and appropriate nursing interventions for infant crying. A cry is a series of four movements that basically resembles a Valsalva maneuver. Documented immediate and long-term sequelae of crying include increased heart rate and blood pressure, reduced oxygen level, elevated cerebral blood pressure, initiation of the stress response, depleted energy reserves and oxygen, interrupted mother-infant interaction, brain injury, and cardiac dysfunction. Caregivers are encouraged to answer infant cries swiftly, consistently, and comprehensively. Kangaroo care is an efficient method for preventing, minimizing, and halting crying. Other interventions for crying include swaddled holding, a pacifier, sugar water, a sweet-tasting nonsucrose solution, heartbeat sounds, distraction by lullabies or mother's voice, rhythmic movement, and reduction of external stimuli.
