Does alcohol play the role of confounder or neuroprotective agent in acute CO poisoning?
문종구 Chonnam National University 2019 국내석사
Objectives: This study investigated whether alcohol influences the predictive value of initial lactate and Glasgow Coma Scale (GCS) score at presentation for the severity of acute carbon monoxide (CO) poisoning and neurologic outcome in patients with acute CO poisoning. Additionally, whether alcohol has a neuroprotective effect after acute CO poisoning was evaluated. Methods: This retrospective study included 158 patients who showed with acute CO poisoning between January 2017 and July 2018 and had an available blood alcohol content (BAC) at presentation. The baseline characteristics, clinical course during hospitalization and neurologic status at 30 days after acute CO poisoning were collected and compared according to BAC. To account for possible confounding or neuroprotective effects of alcohol, BAC was introduced as a continuous variable and a stratified categorical variable in the analysis. Results: The mean and maximum BAC at presentation were 56.8 mg/dL and 408 mg/dL, respectively, in 158 patients presented at a mean of an hour after acute CO poisoning. Lactate, adjusted for previously suggested predictors, was not associated with acute CO poisoning severity; however, after additional adjustment with BAC variables, lactate was associated with CO poisoning severity. Initial GCS score was associated with CO poisoning severity during hospitalization and neurologic outcome at 30 days after acute CO poisoning, regardless of BAC adjustment. BAC variables were negatively associated with CO poisoning severity but not neurologic outcome at 30 days. Discussion and Conclusion: The severity of CO poisoning should be predicted based on serum lactate alone without adjusting for BAC. However, the initial GCS score can be used as a predictor of CO poisoning severity and the neurologic outcome at 30 days after acute CO poisoning regardless of alcohol consumption history. Alcohol does not have a neuroprotective effect on acute CO poisoning. Further study is needed to validate these results.
