Indian red scorpion envenoming

Abstract

The clinical course and treatment outcome of scorpion envenoming in 293 children was studied in a hospital at Mahad in Raigad district of Maharastra. 111 (38%) children who reported 1-10 hours (mean 3.5 hours) after sting had hypertension, 87 (29.6%) with tachycardia reported within 1-24 hours (mean 6.7 hours) of being envenomed and 72 (24.5%) children developed acute pulmonary edema after 6-24 hours (mean 8 hours) of sting. Six victims were brought dead, while 17 (6%) died later owing to multiorgan failure with loss of consciousness and convulsions (who reported after 24 hours of sting). Early administration of prazosin (125-250 ug orally) improved the clinical symptoms. Morbidity and mortality due to scorpion envenoming depends upon time lapse between sting and administration of post synaptic alpha-1 blocker, prazosin hydrochloride.

Scorpion Sting Envenomation in Children: Factors Affecting the Outcome

“…Mortality observed in this study was 8.9% as compared to 1% to 10.7% reported by various authors from different places [11][12][13]. The causes for higher mortality may be late presentations in emergency and associated multiple systemic involvements.…”

Myocarditis with Hypotension after a Scorpion Sting

“…Immediately following a scorpion sting, an autonomic storm is responsible for hypertension, tachycardia, and shock [2]. Cardiovascular effects are particularly prominent after stings by Indian red scorpion (Mesobuthus tamulus) [3]. In the present study, 24-year-old female patient presented with complaint of a scorpion sting and was determined to have myocarditis with left ventricular dysfunction and hypotension.…”

Problems and Paradoxes of Animal Toxins and the Heart

“…Scorpion stings cause a wide range of conditions, from severe local skin reactions to neurologic, respiratory, and cardiovascular collapse. 45 Scorpion venom stimulates the autonomic nervous system, predominantly the sympathetic, which leads to sudden liberation of endogenous catecholamine resulting in an early transient rise in blood pressure, bradycardia, and increased vascular resistance. Clinical manifestations depend on time lapse between sting and hospitalization and/or treatment received at a periphery location.…”
