Background: Water soluble and insoluble chemicals in the pesticide formulation may be eliminated more effectively in time if hemodialysis (HD) and hemoperfusion (HP) are performed concurrently. Aim: This study is aimed at evaluating the efficacy of concurrent HP and HD in patients with acute pesticide intoxication. Methods: Between January 2011 and December 2012, we used HP and HD consecutively (HP-HD group, 347 cases), and then during the next 2 years (January 2013 to December 2014), we used concurrent HP and HD (HPD group, 383 cases). We compared the clinical outcomes between the 2 groups. Results: The mortality was higher in the HP-HD group than in the HPD group: (48.1 vs. 20.9%) for the overall mortality and (81.8 vs. 57.9%) for the paraquat (bipyridylium) mortality (p < 0.001). In multiple logistic analyses, age (p = 0.013), ingested volume (p < 0.001), and HP-HD (p = 0.014) were significant risk factors for mortality in the paraquat ingested group. Conclusion: Concurrent HP and HD would be an effective and safe treatment for patients with acute pesticide intoxication, in particular, paraquat intoxication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
