Abstract:
A 53-year-old woman was brought to the Emergency Department for a persistent state of stupor, tremors, fever and oliguria. The patient had been under treatment for depression. The electrocardiogram showed a wider QRS complex; laboratory tests were as follows: urea 110 mg/dL, creatinine 3 mg/dL, sodium 135 mEq/L, potassium 4.5 mEq/L, and lithium 8.0 mEq/L. Renal replacement was initiated to normalize plasma lithium levels; both stupor and speech impairment persisted for several days after dialysis. Complete recovery was achieved several days afterwards.
