Abstract

Purpose: We investigated the association between continuous renal replacement therapy (CRRT) and mortality after acute glyphosate or glufosinate intoxication. Methods: The electronic medical records of patients with acute herbicide ingestion who were admitted to the regional emergency center of a metropolitan city in Korea from 3/1/2013 to 2/28/2022 were analyzed and reviewed retrospectively. The case group received CRRT, while the control group did not. In total, 96 patients experienced acute herbicide intoxication in the study period. Baseline characteristics were analyzed and compared between the two groups after propensity score matching. The outcome variable was mortality fitted by a Cox proportional hazard model. Results: After full matching between cases of CRRT use and controls (patients who did not receive CRRT) using propensity scores, 96 patients (27 cases, 69 controls) were analyzed. Propensity matching yielded adequate balance (standardized mean differences <0.25) for all covariates. We fit a Cox proportional hazards model with survival as the outcome and CRRT as a factor, including the matching weights in the estimation. The estimated hazard ratio was 0.41 (95% confidence interval, 0.23-0.76; p=0.0044), indicating that CRRT reduced mortality. Conclusion: In this propensity score-matched analysis, CRRT reduced mortality in patients who visited the hospital with acute glyphosate or glufosinate intoxication. In patients with acute herbicide poisoning with high severity calculated by the APACHE II (Acute Physiology and Chronic Health Evaluation II) score and SOFA (Sequential Organ Failure Assessment) score, CRRT should be actively considered to improve the survival rate.
