血气生化仪与自动生化分析仪在急诊生化检验应用中的比较研究

摘要

Objective:To analyze statistically the results of potassium, sodium, chlorine tests by blood-gas biochemical analyzer and automatic biochemical analyzer, in order to have a reference data for blood-gas biochemical analyzer in emergency biochemistry examination.Methods: A total of 101 cases were selected in emergency department. Arterial and venous blood samples of these cases were drawn and tested in electrolyte examination by blood-gas biochemical analyzer and automatic biochemical analyzer. The results of both instruments measured were analyzed statistically.Results: The results of potassium, sodium, chloride ion concentrations tested by blood-gas analyzer ABL80 were lower than the results tested by Beckman AU5800 automatic biochemical analyzer. The correlation analysis were performed in each tested item between the two instruments, and the differences were statistically significant(r=0.997,r=0.992,r=0.989;P<0.05).Conclusion: Although there were differences between two instruments in testing potassium, sodium and chloride ion concentration, the correlation was significant in each test item between the two instruments and the testing speed of blood-gas analyzer ABL80 is faster than the other. Therefore, in order to make quick and accurate clinical judgments about patient's condition, it is worth using blood-gas biochemical analyzer for a preliminary reference in clinical application.%目的：对血气生化仪和全自动生化分析仪的钾、钠、氯的检测结果进行统计学分析，为血气生化仪在急诊生化检验的应用提供参考数据。方法：选取101例急诊入院患者，同时抽取动、静脉血，采用血气生化仪和全自动生化仪进行电解质检查，并对两种仪器所测相同项目的结果进行统计分析。结果：ABL80型血气分析仪所检测的钾、钠、氯离子浓度均低于贝克曼AU5800全自动生化分析仪所测得结果，对两种仪器所测各项目结果分别做相关性分析显示，差异有统计学意义(r=0.997，r=0.992，r=0.989；P＜0.05)。结论：血气生化仪检测钾、钠、氯离子浓度虽然与全自动生化仪有差异，但相关性较好，同时因其检测速度快，为对患者病情作出快速准确判断，使用血气生化仪做为初步参考具有临床应用价值。
