To identify predictive risk factors for myocardial dysfunction in children with scorpion sting envenomation and to evaluate the effects of Scorpion antivenom and prazosin combination therapy on occurrence of myocardial dysfunction.
Observational.
Tertiary care hospital in Southern India.
85 children aged <13 years with scorpion sting envenomation.
Frequency of myocardial dysfunction; predictors of myocardial dysfunction.
24 children (28.2%) developed myocardial dysfunction. Hypotension at admission (P=0.003) and increased time (>4h) between sting and administration of appropriate therapy (P=0.001) were independent predictors of myocardial dysfunction on logistic regression. Scorpion antivenom plus prazosin combination therapy led to an increase in cumulative proportion of children without myocardial dysfunction.
Early (<4 hours) administration of Scorpion antivenom along with prazosin increases the cumulative percentage of children not developing myocardial dysfunction.
确定蝎蜇伤儿童心肌功能障碍的预测风险因素，并评估抗蝎毒血清与哌唑嗪联合治疗对心肌功能障碍发生的影响。
观察性研究。
印度南部的三级护理医院。
85名年龄小于13岁的蝎蜇伤儿童。
心肌功能障碍的发生率；心肌功能障碍的预测因素。
24名儿童（28.2%）出现心肌功能障碍。入院时低血压（P=0.003）以及蜇伤与给予适当治疗之间的时间延长（>4小时）（P=0.001）是逻辑回归中心肌功能障碍的独立预测因素。抗蝎毒血清加哌唑嗪联合治疗导致无心肌功能障碍儿童的累积比例增加。
早期（<4小时）给予抗蝎毒血清联合哌唑嗪可增加未发生心肌功能障碍儿童的累积百分比。
