Standardized Feeding Protocols to Reduce Risk of Necrotizing Enterocolitis in Fragile Infants Born Premature or with Congenital Heart Disease: Implementation Science Needed

Neonatal Intensive Care Workflow Analysis Informing NEC-Zero Clinical Decision Support Design

Decision support in neonatal ICUs is needed, especially for prevention and risk awareness of the devastating complication of necrotizing enterocolitis, a major cause of emergency surgery among fragile infants. The purpose of this study was to describe the current clinical workflow and sociotechnical processes among clinicians for necrotizing enterocolitis risk awareness, timely recognition of symptoms, and treatment to inform decision support design. A qualitative descriptive study was conducted. Focus groups were held in two neonatal ICUs (five groups in Unit A and six in Unit B). Transcripts were analyzed using content analysis and compared with field notes. Clinicians (N = 27) included nurses (37%), physicians (30%), neonatal nurse practitioners (19%), and other staff (16%). Workflow processes differed for nurses (who see necrotizing enterocolitis signs and notify providers to order diagnostic tests and treatments) and providers (who receive notification of necrotizing enterocolitis concern and then decide how to act). Clinicians desired (1) a necrotizing enterocolitis-relevant dashboard to support nutrition tracking and necrotizing enterocolitis recognition; (2) features to support decision-making (eg, necrotizing enterocolitis risk and adherence scoring); (3) breast milk tracking and feeding clinical decision support; (4) tools for necrotizing enterocolitis surveillance and quality reporting; and (5) general EHR optimizations to improve user experience.

Effect of standardized vs. local preoperative enteral feeding practice on the incidence of NEC in infants with duct dependent lesions: Protocol for a randomized control trial

Background

Infants with duct dependent heart lesions often require invasive procedures during the neonatal or early infancy period. These patients remain a challenge for pediatric cardiologists, neonatologists, and intensive care unit personnel. A relevant portion of these infant suffer from respiratory, cardiac failure and may develop NEC, which leads to inadequate growth and nutrition, causing delayed or complicated cardiac surgery.

Methods

This randomized control trial will recruit term infants diagnosed with a duct dependant lesion within the first 72 h of life. After obtaining written parental consent patients will be randomized to either the physician led enteral feeding or protocol-based feeding group. The intervention will continue up to 28 days of life or day of cardiosurgical treatment, whichever comes first. The primary outcomes include NEC and death related to NEC. Secondary outcomes include among others, number of interrupted feedings, growth velocity, daily protein and caloric intake, days to reach full enteral feeding and on mechanical ventilation.

Discussion

Our study will be the first randomized control trial to evaluate if standard (as in healthy newborns) initiation and advancement of enteral feeding is safe, improves short term outcomes and does not increase the risk of NEC. If the studied feeding regime proves to be intact, swift implementation and advancement of enteral nutrition may become a recommendation.

Trial registration

The study protocol has been approved by the local ethical board. It is registered at ClinicalTrials.gov NCT05117164.

Necrotizing Enterocolitis Associated with Congenital Heart Disease-A Review Article

Necrotizing enterocolitis (NEC) is a relatively rare but devastating entity associated classically with the preterm cohort in the neonatal intensive care unit. Preterm and term babies with congenital heart disease are at risk of a number of comorbidities because of the hemodynamic derangements due to a structurally abnormal heart and the corrective procedures adopted. Necrotizing enterocolitis is one of the dreaded complications associated with this cohort and impacts the course of these babies in the hospital in a major way. A large majority of term babies with NEC are in the backdrop of a significant congenital cardiac lesion. This review article summarizes the literature and elaborates this entity including its specific features, risk factors associated with its causality, histopathology and related aspects of hemodynamics, and feeding in this vulnerable population. It also provides insight into modifiable risk factors and early markers of detection of gut necrosis to facilitate prevention and early detection. It highlights the subtle but definite difference in outcome variables to help physicians enable the parents of babies with heart disease to develop a better understanding of the entity and its expected course while counseling.

Enteral Nutrition in Term Infants with Congenital Heart Disease: Knowledge Gaps and Future Directions to Improve Clinical Practice

Optimal nutrition is essential to improve short- and long-term outcomes in newborns with congenital heart disease (CHD). Nevertheless, several issues on nutritional management and concerns about the potential risk of complications related to enteral feeding exist. This narrative review aims to summarize and discuss the available literature on enteral feeding in term infants with CHD. A wide variability in feeding management exists worldwide. Emerging approaches to improve nutritional status and outcomes in infants with CHD include: implementation of a standardized enteral feeding protocol, both preoperative and postoperative, clearly defining time of initiation and advancement of enteral feeds, reasons to withhold, and definitions of feeding intolerance; early minimal enteral feeding; enteral feeding in stable term infants on hemodynamic support; evaluation of enteral feeding in term infants with umbilical arterial catheters and during prostaglandin infusion; assessment and support of oro-motor skills; and promotion and support of breastfeeding and provision of mother's own milk or donor milk when mother's own milk is not available. As evidence from term infants is scarce, available observations and recommendations partially rely on studies in preterm infants. Thus, well-designed studies assessing standardized clinically relevant outcomes are needed to provide robust evidence and shared recommendations and practices.

The effect of early oral stimulation with breast milk on the feeding behavior of infants after congenital cardiac surgery

OBJECTIVE

To investigate the effect of early oral stimulation with breast milk on the feeding behavior of infants after congenital cardiac surgery.

METHODS

Infants with congenital heart disease were randomly divided into the breast milk oral stimulation group (n = 23), physiological saline oral stimulation group (n = 23) and control group (n = 23). Debra Beckman's oral exercise program was used with breast milk and physiological saline in the breast milk oral stimulation group and the physiological saline oral stimulation group, respectively. The time oral feeding and total oral nutrition were started, the length of intensive care unit (ICU) stay and hospital stay, weight and the complications at discharge were recorded for each group and statistically analyzed.

RESULTS

The time oral feeding and total oral nutrition were started and the length of ICU stay and hospital stay were significantly less in the breast milk oral stimulation group and physiological saline oral stimulation group than in the control group (P < 0.05). There were no significant differences in other indicators between the breast milk oral stimulation group and the physiological saline oral stimulation group, except for the time total oral nutrition began (P < 0.05). However, there were no significant differences in weight or complications at discharge among the three groups (P > 0.05).

CONCLUSION

Early oral stimulation exercises with breast milk can help infant patients quickly recover total oral nutrition and reduce the length of ICU and hospital stay after cardiac surgery.
