Relato de caso: infestação da cânula de traqueostomia por miíase

Miiase e uma afeccao causada pela presenca delarvas de moscas em orgaos e tecidos. A incidencia destaparasitose e comum no meio rural entre animais decriacao e, baixa na especie humana. Ocorrenormalmente em pessoas debilitadas, mas pode ocorrerem pacientes troficos e saudaveis. As larvas deCochliomyia hominivorax e Dermatobia hominis, sao osagentes causais mais comuns das miiases humanas naAmerica. O quadro clinico e variavel, pois dependendoda localizacao, podem ser cutâneas, subcutâneas oucavitarias. O principal objetivo desse trabalho foiapresentar um relato de caso de infestacao por miiaseem sitio de traqueostomia em um paciente com carcinomade laringe. A metodologia utilizado foi o relato de casoassociado a revisao de artigos cientificos de bases dedados (Scielo e Pubmed). O diagnostico de miiase humanae clinico, porem para que se possa detectar algumas desuas complicacoes, pode ser necessario examescomplementares. O tratamento convencional da miiaseinclui na remocao das larvas com uso de substânciasquimicas, o que promove a asfixia das larvas e induz suasaida da lesao. Em lesoes maiores ou quando ha celuliteadjacente e indicada a debridacao do local com retiradado tecido necrotico. Myiasis is a disease caused by larvae of flies in organand tissues. The incidence of this parasitic disease iscommon on the agriculture living, for example on animalscreation and uncommon in human being. It occursnormally in weak people, but might occur in healthfulpatients. The larvae of Cochliomyia hominivorax eDermatobia hominis are the more common agents ofmyiasis in American human beings. The symptoms arevariable, therefore depending on the localization, can becutaneous, subcutaneous or in cavities. The main objectiveof this work was to present a case report of infestationby myiasis in the place of tracheostomy in a patient withlarynx carcinoma. The used methodology was casereport associated with scientific article revision ofdatabases (Scielo and Pubmed). The diagnosis of humanbeing myiasis is made by the physical examination,however to detect some of its complications, it can benecessary complementary examinations. Theconventional treatment for myiasis includes the removalof the larvae with chemical substance, which promotesthe larvae?s asphyxia and induces its exit of the injury. Inbigger injuries or when there is adjacent cellulitis it isindicated the surgical hygiene and the necrotic tissue?swithdrawal.
