RESUMO
BACKGROUND: Taurolidine is a molecule with anti-endotoxic, anti-microbial and anti-inflammatory properties that inhibits bacterial adhesion, allowing for its use as lock therapy for the prevention of catheter-related bloodstream infections (CRBSI) in long-term central venous catheters (CVC). AIM: To report a preliminary experience, the first one in Chile, using lock therapy with taurolidine for the prevention of CRBSI and to report its efficacy. METHOD: A taurolidine-based solution was instilled in the CVC of three children with intestinal insufficiency dependent on parenteral nutrition, attended in a Chilean tertiary hospital, and the rate of CRBSI before and after its use was compared in retrospect. RESULTS: In the two patients who started lock therapy immediately after the installation of their CVC, the rate of CRBSI was brought to zero, whereas in the third patient, who had a 9 months-old CVC with a recurrent CRBSI history, an intercurrent CRBSI forced discontinuation of the prophylaxis. CONCLUSIONS: Lock therapy with a taurolidine-based solution prevented CRBSIs when it was begun immediately after installing the CVC, in contrast with an old CVC with a history of recurrent CRBSIs.

INTRODUCCIÓN: Taurolidina es una molécula con propiedades anti-endotóxicas, antimicrobianas y anti-inflamatorias, que inhibe la adhesión bacteriana, lo que ha permitido usarla como terapia de sellado en catéter venoso central de larga duración (CVC) para prevenir infecciones del torrente sanguíneo asociadas a CVC (ITS-CVC). OBJETIVO: Dar a conocer una experiencia preliminar, la primera en Chile, con taurolidina como terapia de sellado para prevenir ITS-CVC y reportar su eficacia. MÉTODO: Se instiló una solución en base a taurolidina en el CVC de tres niños con insuficiencia intestinal, dependientes de alimentación parenteral, atendidos en un hospital terciario de la Región de Valparaíso, y se comparó la tasa de ITS-CVC antes y después de su uso mediante un análisis retrospectivo. RESULTADOS: en los dos pacientes que iniciaron terapia de sellado inmediatamente después de instalado el CVC, la tasa de ITS-CVC se logró llevar a cero, mientras que, en el tercero, portador de un CVC instalado 9 meses antes, con ITS-CVC recurrentes, un nuevo episodio de ITS-CVC obligó a suspender la profilaxis. CONCLUSIONES: La terapia de sellado con solución en base a taurolidina previno las ITS-CVC cuando ésta se inició al momento de instalarse el CVC, no así en un CVC antiguo con ITS-CVC recurrentes.
