ICU重症患者的体温水平对不同血糖测量方法结果影响的比较研究
The impact of temperatures on the results tested with different blood glucose testing methods for critical patients in ICU
目的:对比分析ICU重症患者在不同体温水平下的床旁动脉血气分析与血糖仪快速末梢血糖检测结果。方法同步采集196例ICU重症住院患者的静脉血生化、动脉血气分析和快速末梢血的血糖检测标本,分别计算不同体温水平,不同血糖分组下同步快速血糖检测与静脉血/血生化仪法(标准法)所测血糖值的差异、相关系数、偏倚校正因子及对所得血糖检测结果,进行对照分析。结果正常体温水平下,低血糖组同步快速血糖检测与静脉血糖值结果比较阳性率最低3.31%(5/151),而两两比较中低血糖组与目标组比较,高血糖组与目标组比较,均差异有统计学意义(χ2=38.469、15.504,P<0.01)。发热体温状态下,低血糖组同步快速血糖检测与静脉血糖值结果比较阳性率为0,而两两比较中低血糖组与目标组比较,低血糖组与高血糖组比较,在选择同步快速血糖检测与静脉血糖检测均差异有统计学意义(χ2=18.187、12.857,P<0.01)。结论高体温水平下,不可通过同步快速血糖检测来反映危重患者血糖真实值。
更多Objective To compare the impact on the results tested with arterial blood gas analysis and peripheral blood with glucose meter for critical patients in ICU in different temperature states. Methods The samples of venous biochemical test, blood arterial blood gas analysis and peripheral blood of 196 cases of critical patients in ICU were collected synchronously, and measure the D-value, correlation and bias adjustment factor of glucose blood tested with a synchronous fasting blood glucose test and venous/biochemical analyzer in different temperature states and different blood glucose groups, and the results of blood glucose test were analyzed. Results In normal temperature state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 3.31%(5/151), while the pairwise comparison showed there was both statistical signifcance between hypoglycemia group and target group (χ2=38.469), hyperglycemia group and target group (χ2=15.504) when choosing a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). In high temperatures state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 0. There was both statistical significance between hypoglycemia group and target group (χ2=18.187), hypoglycemia group and hyperglycemia group (χ2=12.857) when choose a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). Conclusions In high temperatures state, a synchronous fasting blood glucose test can not reflect the true value of blood glucose for critical patients.
