Abstract：Objective To compare the role of blood gas biochemical analyzer and automatic biochemical analyzer in emergency biochemical examination.Methods Eighty patients admitted to the emergency department of Qidong People's Hospital from October 2020 to October 2022 were included.The blood gas analyzer and fully automated biochemical immune analyzer were used to detect the electrolyte indicators,the blood collection volume,test time,and potassium,sodium and chloride ion concentrations of the two instruments were compared,and Pearson correlation coefficient was applied to perform correlation analysis on the results of potassium,sodium,and chloride ion concentration detection.Results The blood collection volume and testing time of blood gas biochemical analyzer were lower than those of fully automatic biochemical analyzer[blood collection volume(mL):1.96±0.24 vs.3.72±0.32,testing time(minutes):2.36±0.28 vs.45.54±6.12,both P<0.05].The detection results of potassium,sodium and chloride by fully automatic biochemical analyzer were higher than those by blood gas analyzer[potassium(mmol/L):4.76±1.18 vs.4.12±0.96,sodium(mmol/L):142.18±6.56 vs.137.32±7.16,chloride(mmol/L):99.21±4.32 vs.97.48±3.54,all P<0.05].Pearson correlation analysis showed that the detection results of potassium,sodium and chloride using two instruments were positively correlated(r values were 0.998,0.993 and 0.998,and P values were 0.000,0.000 and 0.000,respectively).Conclusions Both blood gas biochemical analyzer and automatic biochemical analyzer could be used for emergency biochemical examination,and the test results are different,but the correlation is good.The former speed is relatively fast,which could improve work efficiency,so as to meet the needs of emergency better.
