title: Acute lithium intoxication.
abstract: We present a case of acute lithium intoxication in a 51-year-old woman on chronic lithium therapy. Her serum lithium level was 10.6 mmol/l 13 hours after ingestion and 5.8 mmol/l at 24 hours. Dialysis therapy was not employed and she recovered well after fluid resuscitation. Serum lithium levels in chronic intoxication are more indicative of intracellular lithium concentration and therefore of clinical toxicity, as opposed to serum lithium levels in acute intoxication. Clinical features of toxicity are more important than a spot lithium level. A combination of clinical toxicity, the duration of exposure and a serial profile of serum lithium levels should guide dialytic therapy for removal of lithium.
