Improving Neurodevelopmental Outcomes in NICU Patients

Feasibility and Impact of a Pilot Neonatal Cuddler Program on Preterm Infants in the Neonatal Intensive Care Unit

OBJECTIVE

Preterm infants experience daily stress in the neonatal intensive care unit (NICU). Positive sensory experiences mitigate stress responses, but parental participation can be limited by external pressures. This study aimed to describe the impact of a neonatal cuddler program (NCP) on preterm infants' growth.

STUDY DESIGN

A multidisciplinary program trained volunteers to interact with NICU infants when family was not at bedside. Infants were followed prospectively throughout admission. Intervention data included frequency, type, and duration of activity throughout the study period. Student t-test and chi-square test were used to analyze the impact of volunteer interaction on anthropometric measures at discharge.

RESULTS

Forty-five infants interacted with a volunteer (intervention group, n = 45) compared with the control group (n = 56) following coronavirus disease 2019 restrictions. The median (range) time of interaction with a volunteer in the intervention group was 90.0 (5.0-705.0) minutes per infant. Infants in the two groups had similar gestational ages, birth weights, lengths, and occipitofrontal circumferences (OFC). Infants in the intervention group had higher rates of spontaneous intestinal perforation, bronchopulmonary dysplasia, and reached full enteral feeds later. However, rates of severe intraventricular hemorrhage, retinopathy of prematurity, and duration of mechanical ventilation were similar. Infants in the two groups did not differ in the NICU length of stay. At discharge, infants in the intervention group weighed more (p = 0.04) and had higher OFC's (p = 0.01) and OFC z-scores (p = 0.03). The change in z-scores from birth to discharge was significant for the weight (p = 0.02) but not length or OFC. In regression analyses, only group allocation was identified as a significant factor for OFC z-scores at discharge (β= 0.279, p = 0.011) and for change in weight z-scores from birth to discharge (β = 0.226, p = 0.041).

CONCLUSION

Growth is positively impacted by an NCP despite limited interaction. Additional work is needed to demonstrate the impact on neurobehavioral and developmental outcomes.

KEY POINTS

· Establishing and implementing a neonatal cuddler program in a large, level IV NICU is feasible.. · Neonatal cuddler programs can provide positive sensory experiences when parents are not at bedside.. · Even limited exposure to these positive sensory experiences can positively impact growth parameters for preterm infants..

Improving Developmental Positioning in a Level III NICU Using Evidence-Based Teaching and a Standardized Tool: An Evidence-Based Quality Improvement Project

Positioning and handling is a core measure of developmental care that has been universally difficult to implement in the technical NICU environment. Appropriate positioning has been shown to not only improve postural and musculoskeletal outcomes, but enhance sensory development, physiologic stability, thermal regulation, behavioral organization, sleep facilitation, and brain development. In order to improve the developmental positioning practices of bedside nurses in a level III neonatal intensive care unit, a quality improvement project was initiated. Guided by the Iowa Model for Evidence-Based Practice, this project included an evidence-based educational intervention and a standardized positioning assessment tool. After the intervention, there was improvement in knowledge scores, and positioning scores increased from an average of 8.81 +/- 0.19 to 10.93 +/- 0.15.

Using complexity science to understand the role of co-sleeping (bedsharing) in mother-infant co-regulatory processes

Human infants spend most of their time sleeping, but over the first few years of life their sleep becomes regulated to coincide more closely with adult sleep (Galland et al., 2012; Paavonen et al., 2020). Evidence shows that co-sleeping played a role in the evolution of infant sleep regulation, as it is part of an ancient behavioral complex representing the biopsychosocial microenvironment in which human infants co-evolved with their mothers through millions of years of human history (Ball, 2003; McKenna 1986, 1990). This paper is a conceptual, interdisciplinary, integration of the literature on mother-infant co-sleeping and other mother-infant co-regulatory processes from an evolutionary (biological) perspective, using complexity science. Viewing the mother-infant dyad as a "complex adaptive system" (CAS) shows how the CAS fits assumptions of regulatory processes and reveals the role of the CAS in the ontogeny of mother-infant co-regulation of physiological (thermoregulation, breathing, circadian rhythm coordination, nighttime synchrony, and heart rate variability) and socioemotional (attachment and cortisol activity) development.

Establishing a Foundation for Optimal Feeding Outcomes in the NICU

Many infants in the NICU experience difficulties with oral feeding, which contribute to prolonged length of stay. Oral feeding is a complex task involving sensorimotor functioning of the face, mouth, and larynx, as well as coordination of sucking, swallowing, and breathing. The care provided in the NICU starting at birth sets the stage for future oral feeding. The purpose of this article is to describe strategies that will establish a positive foundation to support optimal oral feeding. Nurses can use these strategies to protect newborns from noxious stimuli and promote positive auditory, tactile, gustatory, and olfactory experiences to optimize neurodevelopment for the complex task of feeding.
