Estudo clínico-epidemiológico do acidente escorpiônico em criançase adolescentes no Estado de Minas Gerais no período de 2001 a2005

Abstract

Objectives: Describe and evaluate the Scorpions accidents notified in Minas Gerais state including children and adolescents in the period of 2001 to 2005. Calculate the incidence, and the risk factors related with mortality. Methods: It was made a study of the compulsory notification data of accidents caused by Scorpions in the period between 2001 and 2005 in Minas Gerais state involving children and adolescents. There were analyzed 14,406 notification records of children and adolescents (age between zero and 19 years) with Scorpionism diagnosis. There were excluded 201 patients who did not have age distribution classification or date of birth. After univariate analysis, with mortality factors (p<0,25), it was made logistic regression to makemultivariate analysis. Results: There was an increase of Scorpionism notification along the years. Fifty-five percent were male. The accidents were more prevalent in the period of September to December. Among the cases which was possible the scorpion specie identification (40% ofthe sample), eighty-seven percent were Tityus serrulatus. The most prevalent age distribution was between five and nine years old. Local pain was present in 95% of the cases and the most affected body area was the upper extremity in 46%. The most of the accidents was considered mild (60%) and severe case (7%). The average lethality of that group was 0,7% and it was higher between patients who were one to four years old. On that age distribution, chance to evolve into death was 24 times higher than age distribution of 15 to 19 years old. The serum was administrated in 42% of mild cases. The highest accidentoccurrence was in Belo Horizonte and the highest lethality was in Santa Luzia. The highest incidence was in Conceição das Alagoas and the highest mortality was in Pavão. After multivariate analysis, were identified admission risk factors to evolve into death. The delay of each hour, until the first aid, represents an increase of 9% to evolve into death. Thechance to evolve into death among severe cases is 46 times more than moderate and mild cases. Each year that decrease patients age increase chance to death in 13%. Low blood pressure and respiratory failure at the admission are considered death risk factors.Conclusions: There were a notification increase along the years and accidents peak often occurs between September and December. The most prevalent age distribution was five to nine years old. There were identified as risk factors to evolve into death, delay to first aid, severe cases, the smallest age, low blood pressure and respiratory failure at the admission.
