强离子隙等指标在重症肺炎中的应用价值分析

The application of strong ion gap and other indicators in acute pneumonia

目的探讨强离子隙(SIG)、乳酸和阴离子隙(AG)等指标在重症肺炎中的应用价值。方法在测定血气、血pH、电解质结果基础上,应用Stewart-Figge方法学的方程式计算SIG。结果 223例重症肺炎患者与71例非重症肺炎患者进行比较,钠、钾、SIG、AG、清蛋白(ALB)、pH、磷酸盐及乳酸水平差异均有统计学意义(P<0.05),重症肺炎患者中217例存活患者与6例死亡患者比较,SIG、AG及ALB水平差异有统计学意义(P<0.05)。结论 SIG、乳酸和AG等指标对重症肺炎的诊断、治疗、病情监测具有指导意义;SIG值在重症肺炎患者预后评估中有较大的应用价值。

Objective To investigate the application value of strong ion gap（SIG）,lactic acid,anionic gap（AG） and other indicators in acute pneumonia.Methods SIG was calculated with Stewart-Figge model,based on the results of blood gas,blood pH,and serum electrolytes.Results Comparing 223 acute pneumonia patients and 71 non-acute pneumonia patients,there were significant difference in the results of sodium,potassium,SIG,AG,albumin,pH,phosphate and lactic acid（P0.05）.The results of AG,albumin,and SIG of 217 alive acute pneumonia patients were also significantly different from those of 6 death acute pneumonia patients（P0.05）.Conclusion It might be important of SIG,lactate,AG and other indicators for the diagnosis,treatment,and monitoring of acute pneumonia.The application value of SIG in prognosis of acute pneumonia could be significant.
