研究目的:

1.针对重症肺炎患者能量摄取利用障碍问题,通过全面营养评估明确最佳营养治疗方案、制定标准化营养管理流程与策略,以改善病情、促进康复,为同类患者营养支持提供依据,这是重症营养发展的首要目标。 2.明确重症肺炎患者早期肠内营养胃肠道耐受性现状及喂养不耐受(FI)影响因素,为预防 FI 提供新思路;通过干预降低 FI 发生率,助力患者达标肠内营养,最终降低病死率。 3.突破既往参考其他疾病指南的局限,对比营养支持对重症肺炎与其他危重症患者的影响差异,提出该类患者特有的营养支持方案。 4.筛选可预测重症肺炎患者不良预后的营养学易用性指标,推动临床通过针对性干预改善预后。 5.以多学科协作和循证医学为支撑,通过营养支持加速患者康复、缩短住院时间:既能提高医疗资源利用率、缓解 “看病难”,彰显社会效益;又能降低住院费用、优化医院经济结构,实现医院、医保、医疗多方平衡,达成社会效益与经济效益统一。  

Objectives of Study:

1.For severe pneumonia patients with energy intake/utilization disorders, determine the optimal nutritional therapy via comprehensive assessment, develop standardized nutritional management processes/strategies to improve conditions and promote recovery. This will provide a basis for nutritional support in similar cases and is a primary goal of critical care nutrition. 2.Clarify the status of gastrointestinal tolerance to early enteral nutrition and factors influencing feeding intolerance in severe pneumonia patients to inform FI prevention. Reduce FI through interventions to help patients meet enteral nutrition goals and lower mortality. 3.Move beyond reliance on guidelines for other diseases; compare how nutritional support affects severe pneumonia patients versus those with other critical illnesses, and propose a tailored nutritional support plan for the former. 4.Identify user-friendly nutritional indicators that predict poor prognosis in severe pneumonia patients, prompting targeted clinical interventions to improve outcomes. 5.Leverage multidisciplinary collaboration and evidence-based medicine to accelerate recovery and shorten hospital stays via nutritional support. This enhances medical resource efficiency and eases "difficulty in accessing care" (social benefits), while reducing hospitalization costs and optimizing hospital economic structures. It achieves balance among hospitals, medical insurance, and healthcare, uniting social and economic benefits in practice.
