摘要
目的比较机械通气重症患者测定的静息能量消耗(mREE)与临床医师根据患者病情计算所得的实际营养供给量(pREE)之间的差异,并探讨不同能量缺失程度与预后的关系。方法收集60例机械通气患者的相关资料,进行危重病程度(APACHEⅡ评分)及营养风险评分(NRS 2002),根据患者不同APACHEⅡ评分分为2组,即APACHEⅡ≥15分组和APACHEⅡ<15分组,对2组患者的mREE和pREE进行比较;根据患者能量缺失程度将其分为4组,比较4组间APACHEⅡ评分、住院时间及死亡率的关系。结果按APACHEⅡ评分分组,各组间实际营养供给量、间接测热法测得的静息能量消耗差异有统计学意义(P<0.05)。按能量缺失程度分组,其APACHEⅡ评分、ICU住院日、28 d死亡率差异有统计学意义(P<0.05)。结论间接测热法监测所得的静息能量消耗明显高于临床医师根据患者病情所给的营养供给量,患者能量缺失越严重,病情越重,死亡率越高。
Objective To compare the difference between the resting energy expenditure（ mREE） on critically illness with mechanical ventilation and the real energy expenditure（ pREE） and then assess the correlation the degree of lack of energy and prognosis.Methods 60 mechanical ventilated patients were collected to calculate the scores of the APACHEⅡ and the nutrition risk screening（ NRS 2002）,and then were divided into two groups in terms of the different scores of APACHE,one 15 points,the other≥15 points.Then the mREE and pREE were compared. Those were divided into four parts according to their different lacks of energy,and then the scores of APACHEⅡ,hospitalization and mortality were compared. Results According to the APACHE Ⅱ scores grouping,the actual supply of nutrition and resting energy expenditure measured by the indirect method of measuring thermal of each group was significant difference（ P〈0. 05）; According to the degrees of energy loss of grouping,the APACHE Ⅱ score,ICU length of hospital stay,the mortality rate of 28 d were statistically significant（ P〈0. 05）. Conclusion The resting energy expenditure is significantly higher than that in the nutrition supply given by clinicians on the overall level. The more serious the lack of energy,the more severe status of the patients and there is higher mortality in the patients.
