Abstract

PURPOSE: Extracorporeal elimination of drugs is a critical part of managing poisonings, although the indications and optimal method remain a matter of debate. The aim of this study is to report our clinical experiences with continuous renal replacement therapy (CRRT), as performed by emergency room physicians, as method of extracorporeal drug elimination in patients with poisoning.
METHODS
This study was a retrospective study of the consecutive patients who underwent CRRT, as performed by an emergency room physician, for acute poisoning. The patient characteristics, the kinds of drugs and the method of extracorporeal elimination were analyzed by reviewing the patients'charts.
RESULTS
During eleven months, 26 patients with acute poisoning underwent extracorporeal elimination (2 patients; intermittent hemodialysis, 24 patients; CRRT). The mean time from the decision to performing extracorporeal elimination was 206.0+/-36.8 minutes for intermittent hemodialysis, 62.9+/-8.5 minutes for continuous venoveno-hemodiafiltration (CVVHDF) and 56.6+/-6.8 minutes for charcoal hemoperfusion. For the patients with CRRT, CVVHDF was conducted in 10 patients (3 patients; valproic acid, 2 patients; Lithium, 1 patient; salicylates, 1 patient; methanol) and charcoal hemoperfusion by using CRRT was done in 14 patients (13 patients; paraquat, 1 patient; dapsone). For the 12 patients who required hemodialysis due to severe poisoning, 7 patients underwent CRRT because of their unstable vital signs.
CONCLUSION
CRRT was an effective method of extracorporeal drug elimination in patients with acute poisoning, and especially for the cases with unstable vital sign and for those patients who required an early start of extracorporeal elimination according to the characteristics of the drug.
