Abstract: | We report a case of intravenous malathion poisoning. Serum pseudocholinesterase (PChE) levels were undetectable for 24 hours post injection and increased to 9 IU/mL (normal 7-19) at 7 days. A concomitant decrease of serum malathion was seen with the increasing PChE. The half-life was calculated to be 2.89 hours. |
