A comparative study of severe scorpion envenomation in children caused by Tityus bahiensis and Tityus serrulatus Estudo comparativo do envenenamento escorpiônico grave em crianças provocado por Tityus bahiensis e Tityus serrulatus

From January 1984 to May 1994, 17 of 239 children under 15 years old stung by Tityus serrulatus (15.1%) or Tityus bahiensis (84.9%) presented severe envenoming. Of these 17 patients (1-11 years old; median=2 yr) 14 were stung by T.serrulatus and three by T.bahiensis. All of them received scorpion an...

Of these 17 patients (1-11 years old; median=2 yr) 14 were stung by T.serrulatus and three by T.bahiensis. All of them received scorpion antivenom i.v. at times ranging from 45 min. to 5 h after the accident (median=2h). On admission, the main clinical manifestations and laboratory and electrocardiographic changes were: vomiting (17), diaphoresis (15), tachycardia (14), prostration (10), tachypnea (8), arterial hypertension (7), arterial hypotension (5), tremors (5), hypothermia (4), hyperglycemia (17), leukocytosis (16/16), hypokalemia (13/17), increased CK-MB enzyme activity (>6% of the total CK, 11/12), hyperamylasemia (11/14), sinusal tachycardia (16/17) and a myocardial infarction-like pattern (11/17). Six patients stung by T.serrulatus had depressed left ventricular systolic function assessed by means of echocardiography. Of these, five presented pulmonary edema and four had shock. A child aged two-years old presented severe respiratory failure and died 65 h after being stung by T.serrulatus. Severe envenomations caused by T.serrulatus were 26.2 times more frequent than those caused by T.bahiensis (p<0.001).<br>No período de janeiro de 1984 a maio de 1994, de 239 crianças com até 15 anos de idade, picadas por escorpiões pertencentes às espécies T.bahiensis (84,9%) e T.serrulatus (15,1%), 17 apresentaram envenenamento grave. Destes 17 pacientes, cuja idade variou de 1 a 11 anos (mediana=2anos), 14 foram picados por T.serrulatus e 3 por T.bahiensis. Todos receberam anti-veneno escorpiônico i.v. entre 45 min. e 5 hs após o acidente (mediana=2 horas). À admissão, as principais manifestações clínicas, alterações laboratoriais e eletrocardiográficas observadas foram: vômitos(17), sudorese profusa(15), taquicardia(14), prostração(10), taquipnéia (8), hipertensão arterial(7), hipotensão arterial(5), tremores(5), hipotermia(4), hiperglicemia(17), leucocitose (16/16), hipocaliemia(13/17), aumento da CK-MB (>6% da CK total)(11/12), hiperamilasemia(11/14), taquicardia sinusal(16/17) e padrão semelhante ao infarto do miocárdio(11/17). A ecocardiografia, observou-se depressão da função sistólica ventricular esquerda em 6 pacientes, todos picados por T.serrulatus. Destes, 5 apresentaram edema pulmonar e 4 choque. Uma criança de 2 anos de idade, picada por T. serrulatus, faleceu 65 horas após o acidente devido insuficiência respiratória grave. Conclui-se que os acidentes graves determinados por T.serrulatus foram 26,2 vezes mais freqüentes que os determinados por T.bahiensis (p<0,001).http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0036-46651995000400008Scorpion envenomationTityus serrulatusTityus bahiensis
