Delta values as a prognostic marker in methanol poisoning: a retrospective cohort study

Purpose: The aim of the study was to evaluate mortality prediction performances delta bicarbonate, anion gap, and ratio in methanol poisoning (MP) cases.
 Materials Methods: This clinical study, which followed a cross-sectional design, involved patients with MP who were still alive when they initially arrived at emergency department tertiary care hospital. Patients divided into two groups non-mortality. died during treatment follow-up assigned group, while others non-mortality group. Receiver Operating Characteristic (ROC) analysis used determine cut-off diagnostic value measurements biomarkers predicting mortality. 
 Results: Nine (20%) 45 their follow-up. showed significant difference averages pH, bicarbonate (HCO3-), lactate, HCO3-, ratio, but not partial carbon dioxide pressure (pCO2). In mortality, gap found have outstanding power (AUC>0.9), acceptable (AUC: 0.7-0.8). Conclusion: Delta can be as prognostic factors cases.
