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.
Prospective observational study.
Children admitted with scorpion sting in a tertiary care hospital between December 2009 and November 2010 and followed-up till May 2011.
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.
Scorpion stings, a common and fatal medical emergency in India, produce echocardiographic changes without any long term residual damage on myocardial activity.
蝎子蜇伤在印度和许多其他热带国家是常见的急症。在印度，红蝎子更为常见，其毒液更易导致心肌功能障碍。针对这个问题开展的研究非常少。以下研究在安得拉邦进行，旨在确定儿童蝎子蜇伤后的心血管并发症，并进行为期6个月的随访。
前瞻性观察研究。
2009年12月至2010年11月期间在一家三级护理医院收治的蝎子蜇伤儿童，并随访至2011年5月。
每36例住院病例中就有1例是蝎子蜇伤。最大病例数出现在0至3岁年龄组。76%的病例出现心电图改变，42%的病例出现心肌炎。超声心动图显示射血分数（EF）降低，观察到短暂二尖瓣反流和室壁运动异常。平均EF从第1天的16%分别改善至第5天的47.94%和第14天的59%，具有高度统计学意义。到1个月末，所有幸存者的EF均恢复正常，6个月时未观察到残留心脏功能障碍。
蝎子蜇伤在印度是一种常见且致命的医疗急症，会引起超声心动图改变，但对心肌活动无任何长期残留损害。
