Objective To summarize the evidence related to perioperative nutrition management for lung transplant patients, and to provide reference for formulating nutrition management strategies. Methods Following the 6S Model of evidence acquisition, we searched for evidence on nutritional management for lung transplant patients, including clinical decision support statements, guidelines, expert consensus reports, evidence summaries, systematic reviews and relevant original studies, in domestic and foreign databases and websites from their inception to October, 2024. The quality assessment was conducted by two researchers and the evidence was extracted, evaluated and integrated. Results A total of 12 publications met the inclusion criteria, including 2 clinical decision support statements, 2 guidelines, 5 expert consensus reports, 1 quasi-experimental study and 2 cohort studies. A total of 35 pieces of evidence were summarized into 6 aspects：multidisciplinary team, nutrition risk screening and assessment, body weight management, nutrition requirements, ways and timing of nutritional intervention, postoperative nutrition management， and nutrition monitoring. Conclusion The best evidence on perioperative nutrition management for lung transplant patients can provide evidence-based reference for clinical practice. It is recommended that medical staff should assess the clinical context and combine professional judgement in the process of translating the evidence into practice, thus to provide scientific nutrition management and guidance for patients.
