目的：观察机械通气的脓毒症患者能量消耗与累积能量平衡对其预后的影响。方法：应用间接测热法监测60例脓毒症行机械通气患者的静息能量消耗（MREE），记录每周能量累积平衡，比较存活组与死亡组累积能量差异。采用logistic回归分析患者死亡危险因素。结果：死亡组能量累积负平衡在第二周与第三周明显高于生存组（t＝2．585，P＝0．014；t＝2．903，P＝0．007）。多因素回归分析中，开始喂养时间、能量累积负平衡为死亡危险因素。结论：给予恰当的能量，有效实施营养支持，避免能量摄入不足可能是改善预后的有效手段。

Objective To assess the influence of cumulative energy balance on outcome in septic patients requiring mechanical ventilation. Methods The indirect calorimetry (IC) was used to obtain target energy in 60 septic patients. The cumulative energy balance between survivors and non-survivors were compared. Logistic regressions was used to analyze the risk factors of death. Results Non-survivors had higher negative energy balance than survivors (P<0.05). The logistic regression analysis demonstrated that the start time of feeding and cumulative caloric balance were risk factors of mortality. Conclusions Effective nutrition support might be a good strategy to improve outcomes.
