INTRODUCTION Chylothorax after congenital cardiac surgery is associated with increased risk of malnutrition. Nutritional management following chylothorax diagnosis varies across sites and patient populations, and a standardised approach has not been disseminated. The aim of this review article is to provide contemporary recommendations related to nutritional management of chylothorax to minimise risk of malnutrition. METHODS The management guidelines were developed by consensus across four dietitians, one nurse practitioner, and two physicians with a cumulative 52 years of experience caring for children with CHD. A PubMed database search for relevant literature included the terms chylothorax, paediatric, postoperative, CHD, chylothorax management, growth failure, and malnutrition. RESULTS Fat-modified diets and nil per os therapies for all paediatric patients (<18 years of age) following cardiac surgery are highlighted in this review. Specific emphasis on strategies for treatment, duration of therapies, optimisation of nutrition including nutrition-focused lab monitoring, and supplementation strategies are provided. CONCLUSIONS Our deliverable is a clinically useful guide for the nutritional management of chylothorax following paediatric cardiac surgery.
