General features of acid-base metabolism evaluated during the first three days. (A) pH. (B) Bicarbonatemia. (C) PaCO₂. (D) Chloremia. (E) Lactatemia. (F) Corrected anion gap. *P < 0.05, Tukey's post hoc analysis between survivors (n = 66) and nonsurvivors (n = 89). ^#P < 0.05, Tukey's post hoc analysis vs day 0. Bars represent standard deviations. NS = not significant. PaCO₂ = partial pressure of carbon dioxide.
