Conclusion
In this retrospective data set, application of the Paris guidelines
would have resulted in fewer overall cases of hemodialysis for lithium
poisoned patients, but would have failed to identify a statistically
significant number of patients who may have benefited from expedited
extracorporeal drug removal. While the EXTRIP criteria results in an
increase in the use of hemodialysis, overall patient outcomes were
improved, and fewer patients deteriorated. A prospective study is needed
to more conclusively determine the relative performance characteristics
of both EXTRIP and Paris criteria.
