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。
