Abstract

OBJETIVOS: Descrever e avaliar os acidentes escorpiônicos notificados no estado de Minas Gerais, em crianças e adolescentes, no período de 2001 a 2005, e calcular incidência e mortalidade e identificar fatores relacionados à evolução para óbito. MÉTODOS: Estudo de 14.406 fichas de notificação obrigatória do escorpionismo em Minas Gerais, de pacientes de 0 a 19 anos. Após análise univariada, com fatores relacionados a mortalidade (p OBJECTIVES: To describe and evaluate notified scorpion envenomation incidents in children and adolescents in the Brazilian state of Minas Gerais between 2001 and 2005, and to calculate the incidence and mortality and identify factors related to fatal outcomes. METHODS: Analysis of 14,406 mandatory notifications of scorpion envenomation involving patients aged 0 to 19 years in Minas Gerais. After performing a univariate analysis of factors related to mortality (p < 0.25), multivariate analysis was carried out using logistic regression. RESULTS: The number of notifications of accidents involving scorpions increased over the period. The age group that suffered most accidents was 5 to 9 years. Local pain was reported in 95% of cases. The majority of cases were classified as mild (60%) and antivenom was given to 42% of this population. The mean mortality rate was 0.7%. The state capital, Belo Horizonte, was the municipality with the greatest occurrence of incidents. Each hour's delay before receiving first medical care was associated with a 9% increase in the odds ratio for the likelihood of death, which was 46 times greater in the severe group than in the moderate and mild groups. A decrease of 1 year in patient age was associated with a 13% increase in the odds ratio for the likelihood of death. CONCLUSIONS: There was an increase in the number of notifications over the period studied. The following factors were identified as linked with a higher odds ratio for the likelihood of death: delayed first medical care, being classified as a severe case, and younger age of victim.
