Toxicity

T. trivittatus is the main responsible for more serious accidents in Argentina. A study on the epidemiological clinical aspects of T. trivittatus in Argentina found that the symptoms included pain (85%), edema (26.6%), local burning (24.7%) erythema (20.7%) and local itching (12%); neurological symptoms included paresthesia, cramps, excitation and headache, cardiovascular symptoms involved pallor (18.8%) and tachycardia (18.2%). Dyspnea, hypotension, cardiac arrhythmias, cyanosis, bradycardia and precordial pain occurred in 5% of the cases, along with hypothermia. Vomiting, nausea and sweating also occurred, while headache, arthralgia and paresthesia were mild. The severity of accidents is related to the age group and the amount of venom injected.
