目的:分析危重症病人C-反应蛋白(CRP)与营养不良的关系,为临床判断病情、评估预后、进行治疗提供依据。方法:选取危重症病人140例,于入院后第2天清晨空腹抽取静脉血,测定血清CRP及各项营养指标(总蛋白、清蛋白、血红蛋白、淋巴细胞计数、胆固醇和三酰甘油等),并应用主观全面评价(SGA)法评价病人的营养状况,分析CRP与各项营养指标的关系。结果:①入院病人中营养正常者67例,占47.9%,营养不良者73例,占52.1%;②营养不良组病人CRP明显高于营养正常组(P<0.05);③除淋巴细胞计数和血清三酰甘油外,CRP与多项指标均具有明显相关性(P<0.05)。结论:危重症病人多存在营养不良,CRP与多项营养指标存在相关性。临床医师可根据病人的CRP水平判断其营养状况,评估病情。
Objective: To analyze the relationship between C-reactive protein (CRP) and malnutrition in critically ill patients, and provide the basis for judging the disease, assessing prognosis and treating. Methods: 140 cases of critically ill patients were selected and fasting blood samples were taken on the second day after admission. Serum CRP and various nutritional indicators (total protein, albumin, hemoglobin, lymphocyte count, cholesterol and triglyceride) The subjective comprehensive evaluation (SGA) method was used to evaluate the nutritional status of patients, and the relationship between CRP and various nutritional indicators was analyzed. Results: ①Inpatients with normal nutrition 67 cases, accounting for 47.9%, malnourished 73 cases, accounting for 52.1%; ② malnutrition patients CRP was significantly higher than the normal nutrition group (P <0.05); ③In addition to lymphocyte count and Serum triglyceride, CRP and a number of indicators have a significant correlation (P <0.05). Conclusion: Most critically ill patients have malnutrition, and there is a correlation between CRP and multiple nutritional indicators. Clinicians can judge their nutritional status according to the patient’s CRP level to assess the condition.
