[Assessment of metabolic acidosis in critically ill patients: method of Stewart-Fencl-Figge versus the traditional henderson-hasselbalch approach].
To review strategies of assessment of metabolic acidosis giving emphasis to the of Stewart-Fencl-Figge method versus the traditional method of Henderson-Hasselbalch. ⋯ The traditional Henderson-Hasselbalch approach fails in analyzing the underlying mechanisms of metabolic acidosis and possesses many variables that intervene with its result especially in the critically ill patient. The Stewart-Fencl-Figge method offers a broader analysis of metabolic acidosis, indicating its mechanisms and guiding a better therapeutically strategy. As an alternative, the albumin-corrected and lactate-corrected anion gap seems to be as useful as the Stewart approach in identifying the unmeasured anions.
