Successful treatment of bifenthrin toxicosis using therapeutic plasma exchange.

Objective: To describe a case of bifenthrin toxicosis in a dog with a successful outcome following the use of therapeutic plasma exchange (TPE) and intralipid therapy.

TPE was initiated after lack of significant clinical improvement 12 hours after initial presentation.
