Echocardiologic evaluation and follow-up of cardiovascular complications in children with scorpion sting in coastal South India.

Kumar CM, Prasad SV - Indian J Crit Care Med (2015)

Bottom Line: Echocardiography revealed decreased ejection fraction (EF), transient mitral regurgitation and wall motion abnormalities were observed.Average EF improved from 16% on day 1 to 47.94% and 59% on day 5 and 14 respectively, which was highly statistically significant.By the end of 1 month, all the survivors had normal EF and no residual cardiac dysfunction was observed at 6 months.

ABSTRACT

Introduction and objective: Scorpion stings are a common emergency in India and many other tropical countries. In India, the red scorpions are more prevalent, and their venom is more likely to cause myocardial dysfunctions. There are very few studies conducted on this problem. The following study was done in Andhra Pradesh and aimed to identify cardiovascular complications of scorpion stings in children with a follow-up of 6 months.

Study design: Prospective observational study.

Setting: Children admitted with scorpion sting in a tertiary care hospital between December 2009 and November 2010 and followed-up till May 2011.

Results: Scorpion stings account for 1 in every 36 admissions. Maximum cases were in 0-3 years age group. Electrocardiogram changes were seen in 76% cases and myocarditis in 42% cases. Echocardiography revealed decreased ejection fraction (EF), transient mitral regurgitation and wall motion abnormalities were observed. Average EF improved from 16% on day 1 to 47.94% and 59% on day 5 and 14 respectively, which was highly statistically significant. By the end of 1 month, all the survivors had normal EF and no residual cardiac dysfunction was observed at 6 months.

Conclusion: Scorpion stings, a common and fatal medical emergency in India, produce echocardiographic changes without any long term residual damage on myocardial activity.

Figure 1: Electrocardiogram changes in children with scorpion sting

Mentions: Electrocardiogram changes [Figure 1] were noted in 38 (76%) cases, with sinus tachycardia being the most common finding noted in 36 cases and sinus bradycardia in two cases. ST-segment depression, tall T-waves and T-wave inversion were seen in eight, two and six cases respectively. Low voltage complexes are noted in two cases. On repeating ECG on the 5th day, ECG changes disappeared in most of the cases except in four cases in which T-wave inversion persisted despite clinical improvement. On follow-up T-wave inversion disappeared in one case by 1st week follow-up ECG and in other three disappeared on 1 month follow-up.
