研究目的:

重症患者常处于高度应激状态,机体进入高分解代谢阶段,能量与蛋白质需求显著增加。然而,由于胃肠道功能障碍、手术创伤及药物(如镇静剂、抗生素)的干预,患者易出现营养摄入不足,从而诱发或加剧营养不良 [1] 。已有研究报道,ICU 中营养不良的发生率高达38%~78% [2-4] ,营养不良不仅增加感染风险、肌肉消耗、压疮形成及功能丧失,还显著延长住院时间和提高病死率 [3,5-8] 。因此,优化营养支持,尤其是早期、精准的营养干预,对于改善重症患者预后具有极其重要的意义。  

Objectives of Study:

Severe patients are often in a state of high stress, and their bodies enter a stage of high catabolism, with significant increases in energy and protein requirements. However, due to gastrointestinal dysfunction, surgical trauma, and the intervention of drugs (such as sedatives and antibiotics), patients are prone to inadequate nutrition intake, which can trigger or exacerbate malnutrition [1]. Studies have reported that the incidence of malnutrition in the ICU is as high as 38% to 78% [2-4]. Malnutrition not only increases the risk of infection, muscle consumption, pressure sores, and functional loss, but also significantly prolongs hospital stays and raises mortality rates [3,5-8]. Therefore, optimizing nutritional support, especially early and precise nutritional intervention, is of extremely important significance for improving the prognosis of severe patients.
