Previous issue date: 2014-05-27 / A terapia larval ? a utiliza??o de larvas est?reis no desbridamento de feridas. Atualmente essa t?cnica vem sendo bastante utilizada na Europa, Estados Unidos da Am?rica e Israel, dentre outros pa?ses, entretanto, ainda n?o foi implementada rotineiramente no Brasil e n?o h? relatos de sua aplica??o utilizando larvas da mosca Chrysomya megacephala em pacientes humanos. O presente trabalho objetivou avaliar o desbridamento de ?lceras de dif?cil cicatriza??o utilizando larvas de C. megacephala. Cinco pacientes com ?lceras cr?nicas foram inclu?dos no estudo ap?s responderem a um question?rio, serem esclarecidos sobre os poss?veis riscos e benef?cios da terapia larval e assinarem o Termo de Consentimento Livre e Esclarecido ? TCLE. Antes das aplica??es, foram colhidas amostras para identifica??o das bact?rias presentes nas ?lceras. Ap?s essa etapa, as ?lceras foram avaliadas antes e durante o tratamento atrav?s de registro fotogr?fico, mensura??o de di?metros e avalia??o dos percentuais de tecido necr?tico e de granula??o. A avalia??o foi seguida da aplica??o de aproximadamente cinco larvas est?reis de 2? est?dio de C. megacephala por cm2 de les?o. Os curativos com larvas foram trocados ap?s 48 horas e com 48 horas de intervalo entre as aplica??es. As ?lceras dos pacientes inclu?dos no trabalho apresentaram car?ter polimicrobiano e em todas elas foi isolada a esp?cie Pseudomonas aeruginosa. Todos os pacientes submetidos ? terapia larval apresentaram redu??o significativa do percentual de necrose e aumento do tecido de granula??o na superf?cie das ?lceras e uma consequente melhora no decorrer do tratamento. / Larval therapy is the use of sterile larvae in the debridement of wounds. Currently this technique has been widely used in Europe, the U.S.A., and Israel, among other countries, however, has not been implemented in Brazil yet, and there are no reports of its application using larvae of the fly Chrysomya megacephala in human patients. This study aimed to evaluate the debridement of ulcers difficult to heal by using larvae of C. megacephala. Five patients with chronic ulcers were included in the study after answering a questionnaire, to be informed about the possible risks and benefits of larval therapy and signed a Free, Prior and Informed Consent. Before the applications, samples were collected for identification of the bacteria in the ulcers. After this step, the ulcers were evaluated before and during treatment by photographic recording, measurement and evaluation of diameters, percentage of necrotic tissue and granulation. The evaluation was followed by the application of approximately 5 second instar sterile larvae of C. megacephala per cm2 of lesion. Dressings with larvae were exchanged after 48 hours with 48 hours between applications. The patients? ulcers included in this study had polymicrobial nature and in all of them was isolated Pseudomonas aeruginosa species. All patients underwent larval therapy showed a reduction in the percentage of necrosis, increase of granulation tissue on the surface of ulcers and a consequent improvement during treatment.
