Abstract: ［Abstract］ Objective To analyze the difference of bedside blood gas test results after cardiac surgery， so as to improve the compliance of bedside blood gas test management standards for improving the accuracy of the results. Methods 363 patients in the cardiac intensive care unit from January to February 2018 were selected as the research objects. At the same time， each patient was tested by electrolyte of bedside blood gas analysis and sent to the laboratory for blood biochemistry and routine blood test. The differences of sodium， potassium， blood sugar and hematocrit results obtained by bedside blood gas analyzer and routine biochemical blood test in laboratory were compared， and the influence of different operators on the difference of test results was analyzed. By the Point?of?care testing （POCT） model， the quality management evaluation scores of bedside blood gas testing were collected from January to June 2018. Results The outcomes showed that there were significant differences between the two methods only in the results of blood sodium and hematocrit. Among the objective factors of operators， only basic education has statistical significance. The quality management evaluation score of bedside blood gas test increased from 55 to 93. Conclusion By analyzing the difference between the results of two methods of bedside blood gas detection and laboratory， strict management rules of bedside blood gas analysis are formulated to improve the compliance of implementation。

摘要： ［摘要］ 目的 对心脏术后床旁血气检测结果的差异性进行分析，提高床旁血气检测管理规范执行的依从性，从而提高结果准确度。方法 选择2018年1月至2月心脏重症监护室363例术后患者作为研究对象，每例患者同一时间分别进行床旁血气分析电解质检测和送检验科进行血液生化、血常规检测，对比使用床旁血气分析仪与检验科生化血常规检测分析这两种方法获得的钠、钾、血糖、细胞压积结果的差异性，并分析不同操作者对检测结果差异性的影响。收取2018年1月至6月六个月的床旁血气检测质量管理评定的评分进行对比。结果 两种检测方法仅血钠及红细胞压积两个结果之间存在差异，具有统计学意义。操作者客观因素中，只有基础学历影响具有统计学意义。床旁血气检测质量管理评定评分由原来的55分上升至93分。结论 通过对床旁血气检测与检验科两种检测方法结果的差异分析，临床据此制定严谨的床旁血气分析管理规范，提高其执行的依从性。
