Resumen

COBO SANCHEZ, José Luis et al. Comparative study of the incidence of bacteraemia related to the haemodialysis catheter: bioconnectrs versus direct connection. Rev Soc Esp Enferm Nefrol [online]. 2011, vol.14, n.4, pp.230-235. ISSN 1139-1375.

Objective: To compare hemodialysis catheter-related bacteremia rate between bioconectors use and direct connection. Methodology: Comparative, retrospective and cross-sectional study over 2 consecutive years (one year with direct connection - 2009 February to 2010 February - and 1 year using bioconectors Tego® -2010 March to 2011 March-) in hemodialysis patients in our unit with a permanent catheter as vascular access. Catheters connection and disconnection protocol was the same during the study period, except for the disinfecting solution used: iodine povidone was using in direct connection, and 2% chlorhexidine was using with bioconectors. Catheter-related bacteremia was defined as onset of fever with a positive blood culture in the absence of another infection source. Results: 69 patients were studied: 36 during direct connection period and 33 during use bioconectors period. Six patients were studied during both periods. Bacteremia rate during direct connection period was 24.6/1000 catheters-day (9 bacteremia), while during the using bioconectors period, bacteremia rate was 5.47/1000 catheters-day (2 bacteremia) (p = 0.036). Staphylococcus aureus (3 patients) and staphylococcus coagulase negative (3 patients) were the most common infectious agents during direct connection period. Conclusions: Use of bioconectors significantly decreases the rate of bacteremia catheter-related in hemodialysis patients versus direct connection.
