Abstract:
Objective:To investigate the prognostic value of strong ion gap (SIG) in acute paraquat (PQ) poisoning.Methods:Seventy-two PQ poisoning cases were enrolled into a retrospective analysis, which were divided into 2 groups, survival group ( n=18) and death group ( n=54). The levels of SIG, anion gap (AG),pH, HCO 3-, and lactic acid were compared between the two groups. ROC analysis was used to evaluate the prognostic value of these indexes in PQ poisoning patients. Results:The levels of SIG, AG, HCO 3- and lactic acid were significantly different in the survival group and death group ( P < 0.05). The area under curve of each index was as follows: SIG (0.956) > AG (0.917) > lactic acid (0.778) > HCO 3- (0.635) > pH (0.437). The Youden indexes were as follows: SIG (0.60) > AG (0.321) > lactic acid (0.113). Conclusions:SIG shows a better prognostic value in PQ poisoning compared to other acid-base imbalance indexes.
