In order to assess the therapeutic value of 1,3 butanediol in ethylene glycol toxicosis, mixed-bred dogs were given an oral dose of commercial antifreeze at 6 ml/kg of body weight (0 hour) and treated (IV) 7 times at 6-hour intervals with 5.5 ml/kg of body weight 1,3 butanediol solution (20% in physiological saline solution) beginning at 8, 12, and 21 hours. Serum glycolic acid concentration was quantitated by high-pressure liquid chromatography. Three dogs that were given ethylene glycol, but no 1,3 butanediol treatment, died with elevated serum glycolic acid concentrations. Five dogs were given ethylene glycol and 1,3 butanediol treatment. Of 2 dogs treated at 8 hours, 1 survived and 1 died at 39 hours; 1 treated at 12 hours and 1 treated at 21 hours survived; 1 dog died soon (27 hours) after treatment was initiated at 21 hours. Four of the 5 dogs had dramatically decreased serum glycolic acid concentrations after 1,3 butanediol treatment, indicating its effectiveness in inhibiting alcohol dehydrogenase-dependent glycolic acid formation in vivo.
