The use of Tablo continuous veno-venous haemodialysis to rapidly remove lithium in a patient with severe lithium toxicity

Abstract

We report a case of severe, life-threatening lithium toxicity in a patient with bipolar I disorder who presented with altered mental status and acute renal failure. At admission, serum lithium level was well above toxic levels (>2 mEq/L). The signs and symptoms of lithium toxicity significantly improved after treatment with continuous veno-venous haemodialysis (CVVHD). The patient was discharged with no neurological or renal sequelae. Herein is the first case report using the Tablo CVVHD system to treat severe lithium toxicity.
