The association of malnutrition with surgical morbidity and mortality is well recognized. The question of whether this relationship is causal or simply an association in sick patients has been hotly debated. The field of nutrition support has grown out of the belief that correcting malnutrition will modify associated risks for poor outcome. It has been easier to substantiate this belief in some clinical situations than in others. The evidence for nutrition support during the perioperative period is reviewed and recommendations are made about where nutrition support is most useful and where it may be counterproductive. Some of the important unanswered questions about perioperative nutrition support are raised.
营养不良与手术并发症及死亡率之间的关联已得到广泛认可。这种关系是因果关系还是仅仅是患病患者中的一种关联，这一问题一直备受激烈争论。营养支持领域的发展源于这样一种信念，即纠正营养不良将改变不良结局的相关风险。在某些临床情况下，证实这一信念比在其他情况下更容易。本文回顾了围手术期营养支持的证据，并就营养支持最有用的地方以及可能适得其反的地方提出了建议。还提出了一些关于围手术期营养支持的重要未解决问题。
