Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / A importÃncia dos praguicidas como agente causal de intoxicaÃÃes e Ãbitos à evidenciado pelo nÃmero de ocorrÃncias registradas, principalmente nos paÃses em desenvolvimento. No Brasil, os praguicidas ocupam a terceira posiÃÃo dentre os agentes responsÃveis por intoxicaÃÃes agudas. Eles agem por inibiÃÃo enzimÃtica (acetilcolinesterase) de modo irreversÃvel, podendo provocar aparecimento de sinais e sintomas colinÃrgicos caracterÃsticos. Podem causar ainda o aparecimento da sÃndrome intermediÃria e da polineuropatia tardia. Este estudo teve como objetivos traÃar o perfil epidemiolÃgico dos pacientes intoxicados no estado do CearÃ, no perÃodo de fevereiro a julho de 2004, atendidos no Centro de AssistÃncia ToxicolÃgica do Cearà (CEATOX); avaliar o tratamento proposto; verificar os sinais e sintomas das sÃndromes colinÃrgica e intermediÃria e analisar os fatores de risco associados à evoluÃÃo dos pacientes. Foi realizado um levantamento de dados preliminares referentes a janeiro de 2002 atà junho de 2003. A coleta dos dados foi realizada a partir dos prontuÃrios mÃdicos, fichas de notificaÃÃo do CEATOX e entrevista com o paciente ou responsÃvel. Foram analisados 19 pacientes, sendo 10 (52,6%) do sexo masculino e 9 (47,4%) do feminino. A mÃdia de idade foi 27,8Â11,4 anos. A ocupaÃÃo trabalhador agrÃcola representou 42,1% (8/19). As tentativas de suicÃdio representaram 84,2% (16/19) dos casos. Houve 4 (21,1%) Ãbitos. As principais manifestaÃÃes clÃnicas foram diarrÃia (78,9%), miose (57,9%) e sialorrÃia(52,6%). Fez-se dosagem da AChE na admissÃo dos pacientes intoxicados, sendo mÃdia e desvio-padrÃo 1,06Â1,50 UI/mL. As demais dosagens foram feitas no decorrer do internamento de cada paciente. Dentre as complicaÃÃes clÃnicas, as do trato respiratÃrio foram as mais importantes (57,2%). Atropina foi administrada em 16 (84,2%) dos pacientes. A mÃdia de internaÃÃo foi 8,6Â8,5dias. Houve associaÃÃo estatÃstica quando se comparou ventilaÃÃo, tempo de UTI e tipo de intoxicaÃÃo com o surgimento de complicaÃÃes clÃnicas (p<0,05) (teste do qui-quadrado e exato de Fisher). A regressÃo logÃstica nÃo mostrou significÃncia estatÃstica quando analisou risco de Ãbito a partir das variÃveis em estudo. Os resultados mostraram que se faz necessÃrio uma reestruturaÃÃo no protocolo de atendimento e tratamento dos pacientes intoxicados com IOF, bem como sua divulgaÃÃo no hospital Instituto Dr. Josà Frota e em outras unidades hospitalares. Os resultados demonstram ainda a situaÃÃo crÃtica quanto ao uso inadequado de praguicidas organofosforados no estado do Cearà e a necessidade de orientaÃÃo ao consumidor e adequada vigilÃncia sanitÃria quanto ao uso e comercializaÃÃo dos mesmos. / The importance of the pesticides causal agent of intoxication and deaths is clearly shown by the number of registered cases, mainly in developed countries. In Brazil, pesticides places the third more important group of substances responsible for acute intoxication. They act through enzymatic inhibition (acetylcholinesterase) in an irreversible way, leading to characteristic cholinergic signs and symptoms. They are also able to cause the intermediary syndrome and the delayed polyneuropathy. This study aimed to set out the poisoning patientsâ epidemiological outline in Cearà state, observed from February to July 2004, who received medical care at Centro de AssistÃncia ToxicolÃgica do Cearà (CEATOX); evaluating the proposed treatment; verifying the signs and symptoms related to the cholinergic and intermediary syndromes; analyzing the risk factors matched to patients recovery. Some preliminary data were obtained from January 2002 to June 2003 concerning to these poisoning events. The data collection was performed from medical recording, CEATOX notification files and patients or their companion interviews. 19 patients were analyzed, 10 (52,6%) men and 9 (47,4%) women. The average age was 27,8  11,4. Agriculturists represented 42,1% (8/19) of all cases. Attempted suicide constituted 84,2% (16/19). There were 4 (21,1%) deaths. The main clinical observations were diarrhea (78,9%), myosis (57,9%) and sialorrhea (52,6%). The AChE levels were measured immediately after admission and expressed in terms of mean  standard deviation (1,06  1,50 UI/mL). The other AChE measurements were performanced during the permanence of the patients in the hospital. Among clinical complications, those ones related to the respiratory tract were the most relevant (57,2%). Atropine was administered to 16 (84,2%) patients. The average time of admission was 8,6  8,5 days. There was statistical association when were compared ventilation, time spent in the ICU and type of intoxication with clinical complications (p<0,05) (Chi-square test and Fisherâs test). The logistic regression did not show statistical differences when the death risk was analyzed comparing to the studied variables. The results stress the need to adopt more suitable measures with a restructured protocol in handling patients intoxicated with IOF, giving ample publicity at the hospital units of Dr. Josà Frota Institute and others. The data obtained also point out the critical situation in Cearà State in the use, misure or inappropriate vigilance by the sanitary authorities.
