Modificación de la flora conjuntival por el empleo de soluciones de higiene palpebral / Modification of the conjuntival flora with cleaning papebral solutions

Objetivo: El objetivo del presente trabajo consiste en valorar la efectividad de una solución de higiene palpebral en el preoperatorio de cirugía de cataratas así como las modificaciones en la flora conjuntival. Material y métodos: Estudiamos 286 pacientes divididos en 5 grupos. Un grupo control que no utilizó el producto y los 4 restantes que emplearon el producto durante 3, 4, 5 y 6 días respectivamente. El diseño del estudio fue prospectivo, randomizado y enmascarado. Se tomó una muestra de fondo de saco conjuntival en la mañana del día de la cirugía, previa a la instilación de colirios. Las muestras fueron sembradas y analizadas según las técnicas microbiológicas. Resultados: El tiempo óptimo de utilización de las soluciones de higiene palpebral en el preoperatorio de cirugía de cataratas es de 4 a 5 días. Si se usan menos de tres días no se reduce la tasa de cultivos positivos y si se aplican más de seis se aíslan microorganismos que no forman parte de la flora conjuntival habitual. Conclusión: En caso de utilizar productos de higiene palpebral no deben prolongarse más de cinco días consecutivos previo a la cirugía de cataratas(AU)

Objective: The aim of the present study is to evaluate the effectiveness of a solution of palpebral hygiene during the preoperative stageof cataract surgery. Materials and methods: We studied 286 patients divided in 5 groups. One control group that did not use the product, and the remaining 4, that used the product during 3, 4, 5 and 6 days. The design of the study was prospective, randomize and masked. We took a sample of the conjunctival fundus in the morning of the day of the surgery, before commencing treatment with eye drops. This sample was sown according to microbiological techniques and analyzed by the microbiology department. Results: The best time for using palpebral hygiene solutions prior to cataract surgery is four to five days. If it is used at less than three days, it does not decrease the rate of positive cultures and if the solution is applied more than six days, microorganisms that are not part of the common conjunctival flora may appear. Conclusions: Palpebral hygiene products should not be used more than five consecutive days previous to surgery(AU)
