Canine nerve agent antidotes
Atropine: 0.2 - 2 mg/kg IM. 30 kg (66#) canine, IM = 6 to 60 mg Mark I injector contains only 2 mg!
2-PAM Chloride: 10 - 20 mg/kg IM 30 kg canine = 300 to 600 mg. The Mark I injector contains 600 mg (The LD50
for dogs is 190 mg/kg, so the injector dose should be relatively safe for dogs over 10kg)
Diazepam: 0.2 - 2 mg/kg IV for seizure control, used to
effect. The CANA injector contains only 2 mg for IM use IM diazepam in dogs unpredictably absorbed

Blast injuries
1. Primary: from blast wave injury to tissues Mainly affects organ systems with a high
air to fluid ratio (auditory, pulmonary and GI.)
2. Secondary injuries: from bomb fragments or flying debris
3. Tertiary: victim propelled into stationary objects
4. Other: Burns, smoke, radiation

Principles of Veterinary Triage
General medical triage nomenclature Green: Minor (walking wounded) Yellow: Delayed treatment OK Red: Needs immediate care Black: Dead/going to die
Veterinary professionals would triage for animals and potentially could triage people in catastrophic situations.
