ABSTRACT

Objective: To determine the concordance of glucose, sodium and potassium in peripheral arterial and venous samples in critically ill children.
Material and methods: We included results of glucose, sodium and potassium peripheral arterial and venous samples of hospitalized children in the emergency department and the pediatric intensive care unit at Children’s Hospital of Sinaloa. For statistical analysis paired t-test was used for continuous variables. We determined the correlation between the two techniques by the Pearson correlation coefficient (r) and the method of Bland and Altman.
Results: One hundred fifty one paired samples were processed. There was no statistically significant difference in mean glucose values in the sample peripheral venous blood and p = 0.97. The agreement was adequate for the Pearson correlation coefficient (r = 0.96) but not by the method of Bland and Altman. For sodium and potassium observed statistically significant differences in means p ‹ 0.001, although the agreement was good for both ions, r = 0.94 and r = 0.92 respectively, whereas by the method of Bland and Altman found important variability in the results of two tests.
Conclusions: Although our study results in peripheral arterial and venous samples showed a good correlation for the Pearson correlation coefficient, the clinician should be cautious in interpreting the results of glucose, sodium and potassium blood gas samples mainly from patients severe.
