Failure to thrive is common in infants with hypoplastic left heart syndrome and its variants and those with poor growth may be at risk for worse surgical and neurodevelopmental outcomes. The etiology of growth failure in this population is multifactorial and complex, but may be impacted by nutritional intervention. There are no consensus guidelines outlining best practices for nutritional monitoring and intervention in this group of infants. The Feeding Work Group of the National Pediatric Cardiology Quality Improvement Collaborative performed a literature review and assessment of best nutrition practices from centers participating in the collaborative in order to provide nutritional recommendations and levels of evidence for those caring for infants with single ventricle physiology.
Adequate caloric intake plays a vital role in the course of illness and the recovery of critically ill patients. Nutritional status and nutrient delivery during critical illness have been linked to clinical outcomes such as mortality, incidence of infection, and length of stay. However, feeding practices with critically ill pediatric patients after cardiac surgery are variable. The Pediatric Cardiac Intensive Care Society sought to provide an expert review on provision of nutrition to pediatric cardiac intensive care patients, including caloric requirements, practical considerations for providing nutrition, safety of enteral nutrition in controversial populations, feeding considerations with chylothorax, and the benefits of feeding beyond nutrition. This article addresses these areas of concern and controversy.
Objective: A standardised multi-site approach to manage paediatric post-operative chylothorax does not exist and leads to unnecessary practice variation. The Chylothorax Work Group utilised the Pediatric Critical Care Consortium infrastructure to address this gap. Methods: Over 60 multi-disciplinary providers representing 22 centres convened virtually as a quality initiative to develop an algorithm to manage paediatric post-operative chylothorax. Agreement was objectively quantified for each recommendation in the algorithm by utilising an anonymous survey. “Consensus” was defined as ≥ 80% of responses as “agree” or “strongly agree” to a recommendation. In order to determine if the algorithm recommendations would be correctly interpreted in the clinical environment, we developed ex vivo simulations and surveyed patients who developed the algorithm and patients who did not. Results: The algorithm is intended for all children (<18 years of age) within 30 days of cardiac surgery. It contains rationale for 11 central chylothorax management recommendations; diagnostic criteria and evaluation, trial of fat-modified diet, stratification by volume of daily output, timing of first-line medical therapy for “low” and “high” volume patients, and timing and duration of fat-modified diet. All recommendations achieved “consensus” (agreement >80%) by the workgroup (range 81–100%). Ex vivo simulations demonstrated good understanding by developers (range 94–100%) and non-developers (73%–100%). Conclusions: The quality improvement effort represents the first multi-site algorithm for the management of paediatric post-operative chylothorax. The algorithm includes transparent and objective measures of agreement and understanding. Agreement to the algorithm recommendations was >80%, and overall understanding was 94%.
Background Ventricular assist devices (VADs) support children with heart failure. The objective is to report on the nutrition outcomes of children requiring VAD. Methods This was a retrospective study performed in a tertiary care center. All patients undergoing VAD placement from 2010 to 2018 were included. Exclusion criteria were VAD placement in outside hospitals, missing baseline anthropometrics, and death in the first 15 days post‐VAD. Clinical, demographic, and nutrition data were collected from baseline and at 2 months post‐VAD. Descriptive statistics were used. Results Of the 52 patients who had undergone VAD placement, 49 (65% male, 80% with cardiomyopathy; median age at VAD, 8 years) met the study criteria. The median length of stay following VAD was 63 days. Eight patients (16%) had malnutrition at baseline (five mild, two moderate, and one severe). At 2 months post‐VAD, seven (of 49) patients had undergone heart transplantation and three (6%) were deceased. The proportion of patients with malnutrition was significantly different at 2 months post‐VAD (P = 0.009), with six patients showing evidence of malnutrition (three mild, two moderate, and one severe; body mass index z score at baseline vs 2 months: 0.11 (± 1.72) vs 0.43 (± 0.94), P = 0.049). The percent of required energy consumed increased from 77% at baseline to 90% at 2 months post‐VAD (P = 0.021). The proportion of patients fed solely enterally also increased (62% vs 84%, respectively; P = 0.042). Conclusion VADs are associated with improved nutrition outcomes. Future studies should investigate the impact of VADs on body composition and longer‐term outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
