增龄可导致器官功能减退和代谢能力下降，营养不良和衰弱发生率增加，以及术后不良临床结局。预康复是指患者在面对手术等主要生理压力时，接受的术前干预训练，老年外科患者因其代谢特点是预康复的适宜对象。多维预康复技术核心内容包括运动、营养及心理，运动锻炼方案趋于个性化，营养干预包含口服营养补充和营养咨询，心理辅导以消除焦虑和鼓励完成预康复计划。目前有较多临床研究支持多维预康复能提升老年外科患者的术后行走能力，降低并发症发病率，在卫生经济学等方面的效果尚需更多的研究确证。“,”Aging can lead to organ dysfunction and metabolic decline, increased incidence of malnutrition and frailty, and postoperative adverse clinical outcomes. Prehabilitation refers to the preoperative intervention training received by patients confronted with major physiological stress such as surgery. Geriatric surgical patients are suitable objects for prehabilitation considering their metabolic characteristics. The core content of multimodal prehabilitation technology includes exercise, nutrition and psychology. Exercise program tends to be personalized, nutritional intervention includes oral nutrition supplement and nutrition counseling, and psychological support is provided to eliminate anxiety and encourage the completion of prehabilitation plan. At present, evidence from many clinical studies supports that multimodal prehabilitation can improve postoperative walking ability of geriatric surgical patients and reduce the incidence of complications. More studies are needed to confirm the effect in health economics and other aspects.
