ABSTRACT

Using formulate to determine the anion gap is currently a useful tool in the interpretation of acid-base balance. There are many equations sustained by electroneutrality that have proven correlation with each other in adults. However, given the peculiarity of infants, these formulas can not show similarities. Objective: To estimate the degree of correlation between pH, AG, and GIF by Stewart and Gilfix critically ill neonates. Methods: In a prospective cohort of infants cared for in a neonatal intensive care a comparative study was conducted with laboratory blood gases and taken to income, with which were calculated by the following formulas: anion gap with and without the inclusion of potassium, strong ion gap formula of Stewart and Gilfix base difference. For statistical analysis, descriptive and inferential statistics were performed using Spearman correlation test and linear correlation with pH and formula Stewart. SPSS version 20 was used. Results: The formulas were calculated on 146 blood gases, finding a statistically significant correlation with the formula of strong ion gaps with the anion gap, unlike real bases. The best way to predict units change equation Stewart was the base deficit. Conclusions: Anion gap Gilfix formula and have good correlation with the Stewart.
