Abstract:
Objective To investigate the influence of different storage and time on the arterial blood gas analysis.Methods This study used a randomized controlled repeated survey design, and totals of 120 samples of arterial blood were divided into two groups by random.The blood samples of group 1 were stored in 4 ℃refrigerator, while the samples of group 2 were stored at 0℃ice box.All blood samples were tested immediately at half an hour, one hour, an hour and a half and two hours.Results pH,PaCO2 ,PaO2 ,SaO2 of the two groups had no statistically significant difference (P>0.05).But there were statistically significant differences in test results at different time points (P<0.01).With the prolonged time of samples set aside, the value of pH, PaO2 and SaO2 showed a decreasing trend, while the PaCO2 value gradually increased.Conclusions The test results of blood samples stored in 4℃refrigerator or 0℃ice box show no difference, and every arterial blood sample should accomplish the test in 30 minutes, otherwise it would affect the results of blood gas analysis.
