Objective To search, evaluate and summarize the best evidence on the management of enteral feeding intolerance in children after surgery for congenital heart disease, and to provide a basis for medical staff to carry out clinical practice. Methods All evidence related to enteral feeding intolerance management in children after surgery for congenital heart disease was systematically searched from relevant Chinese and English databases, guideline websites, and relevant professional association websites. Our search included clinical decisions, guidelines, evidence summaries, systematic reviews, expert consensus and original studies. The search period was from setup of database to April 1, 2023. Two evidence-based trained investigators independently assessed the quality of the included literature, extracted and synthesized the evidence. Results A total of 15 articles were included, including 1 recommended practice, 3 guidelines, 5 expert consensuses, 4 systematic reviews, and 2 randomized controlled studies. 24 best pieces of evidence were summarized from five aspects: assessment and monitoring of feeding intolerance, nutritional preparations, feeding methods, symptom management, and management strategies. Conclusion The best evidence for the management of enteral nutrition feeding intolerance in children after congenital heart surgery summarized in this study can provide an evidence-based basis for further enhancing nutritional management of children and promote disease recovery and improve the quality of clinical care.
