ABSTRACT

Objective:

To determine the in vitro toxicity of different concentrations of sevoflurane in cells exposed to X-ray.

Methods:

The genotoxic effects of sevofluorane were studied by means of the micronucleus test in cytokinesis-blocked cells of irradiated human lymphocytes. Subsequently, its cytotoxic effects on PNT2 (normal prostate) cells was determined using the cell viability test (MTT) and compared with those induced by different doses of X-rays.

Results:

A dose- and time-dependent cytotoxic effect of sevofluorane on PNT2 cells was determined (p >0.001) and a dose-dependent genotoxic effect of sevofluorane was established (p >0.001). Hovewer, at volumes lower than 30 μL of sevofluorane at 100%, a non-toxic effect on PNT2 cells was shown.

Conclusion:

sevofluorane demonstrates a genotoxic capacity as determined in vitro by micronucleus test in cytokinesis-blocked cells of irradiated human lymphocytes.
RESUMEN

Objetivo:

Determinar la capacidad genotóxica del anestésico sevofluorano en en células expuestas a radiación ionizante.

Métodos:

La genotoxicidad del sevofluorane se determinó mediante el test del bloqueo citocinético de linfocitos humanos irradiados bloqueados con citochalasina. La capacidad citotóxica se determinó mediante el test de viabilidad celular e inhibición del crecimiento celular (MTT) en células PNT2 (epiteliales de próstata), comparando sus resultados con los inducidos por diferentes dosis de rayos X.

Resultados:

Se ha determinado un efecto citotóxico del sevofluorane sobre las células PNT2 que presenta correlación con la dosis administrada y el tiempo de estudio utilizado (p >0.001), así como un efecto genotóxico con características dosis-dependientes (p >0.001). Sin embargo, con volúmenes de sevofluorane puro inferiores a 30 μL no encontramos efecto citotóxico sobre las células PNT2.

Conclusión:

Sevofluorane muestra una significativa capacidad genotóxica in vitro determinada mediante el test de micronúcleos en linfocitos humanos irradiados con bloqueados citocinético mediante citochalsina.
