Abstract
Introduction: Scorpion envenomation is one of the life-threatening factors and health challenges in tropical and subtropical areas. Annually, scorpion envenomation is reported in 1.2 million cases and the mortality rate is high among children. Considering the complications on the cardiovascular system caused by scorpion venom and the importance of early diagnosis of heart problems in stung children, this study aimed to investigate the relationship between cardiac dysfunction diagnosed by Doppler Echocardiography and Tissue Doppler Imaging methods in patients with scorpion envenomation in Bandar Abbas Children's Hospital in 2017. Method: This descriptive-analytic study was performed on 80 children aged between 2 months to 14 years who were suffering from scorpion envenomation. All patients had normal echocardiography and tissue doppler for evaluation of systolic function and mitral inflow echo for evaluation of left ventricular diastolic function by pediatric cardiologist during the first 24 hours post hospitalization (12-72 hours after envenomation). Data were analyzed using SPSS 23 Statistical Software and the proper statistical tests. P-value <0.05 was considered as the significance level for this study. Results: In this study, 38 patients (47.5%) were girls and 42 (52.5%) were boys with the mean age of 2.59 ± 0.882 years. The time between the scorpion sting and the referral to the hospital was 3.25 ± 1.55 hours. In this study, 12.5% had Tachycardia. In this study, abnormal cardiac function was detected by Ejection Fraction method was 2.5%, by E / Ea 10%, by Aa wave 8.8%, and by S-wave tissue doppler was 10%. However, no abnormality was reported by Isovolumic Relaxation Time. Conclusion: The abnormality of systolic function was reported in 2.5% and 10% of patients using EF wave method and S-wave method respectively. Also, using tissue doppler, most abnormalities in diastolic function were reported by E/E wave method (10%). It is recommended that both Doppler Echocardiography and Tissue Doppler Imaging methods be used for patients stung by scorpions for evaluation of cardiac function and the possible complications of envenomation.
