Assessment of a general therapeutic protocol for the treatment of acute T-2 toxicosis in swine.

T-2 toxin, a trichothecene mycotoxin suspected of being used as a chemical warfare agent, was administered iv to swine at a dose of 3.6 mg/kg body weight (iv LD50 approximately 1.2 mg/kg). Four different therapeutic protocols were assessed for their efficacy in the treatment of the resultant acute T-2 toxicosis syndrome. One therapeutic protocol included the combined use of metoclopramide, activated charcoal, magnesium sulfate, dexamethasone sodium phosphate, sodium bicarbonate and normal saline. The other 3 protocols utilized the same agents less 1 of the following: the combination of activated charcoal and magnesium sulfate, sodium bicarbonate, or normal saline. All 4 treatment groups showed improved survival times compared to a positive T-2 control group. Within the limits of the study, it would appear that the removal of activated charcoal and magnesium sulfate was most detrimental to the T-2 toxin-dosed swine.
