ABSTRACT

INTRODUCTION: The presence of an active bacteremia has been considered a relative contraindication to perform an intrathecal puncture due to the risk of causing meningitis or epidural abscess. However, a clear and definite causal relationship has not yet been demonstrated. OBJECTIVES: To determine the relationship between intrathecal puncture and the development of meningitis in sub-jects with bacteremia. MATERIALS AND METHODS: Experimental study in rats with chronic bacteremia to which dural puncture was performed. Meningitis was then evaluated by direct drainage of the cisterna magna and histopathological studies of brain tissue. RESULTS AND CONCLUSION: 12 of 40 bacteremic rats that underwent intrathecal puncture developed meningitis. Previous administration of antibiotics seems to reduce this risk.


INTRODUCCIÓN: Se ha considerado la presencia de una bacteremia activa como contraindicación relativa para realizar una punción intratecal por el riesgo de provocar meningitis o absceso peridural. Sin embargo, aún no se ha podido demostrar una relación causal clara y definida. OBJETIVOS: Determinar la relación entre punción intratecal y el desarrollo de meningitis en sujetos con bacteremia. MATERIALES Y MÉTODOS: Estudio experimental en ratas con bacteremia crónica a las que se les realizó punción dural, luego se evaluó la presencia o no de meningitis mediante drenaje directo de la cisterna magna y estudios histopatológicos de tejido cerebral. RESULTADOS Y CONCLUSIÓN: 12 de 40 ratas bacterémicas a las que se le realizó punción intratecal desarrollaron meningitis. La adminis-tración previa de antibiótico parece disminuir este riesgo.
