MEDINA, Julio et al. Conducta frente a la sospecha de infección relacionada a catéter venoso central para hemodiálisis. Rev. Méd. Urug. [online]. 2006, vol.22, n.1, pp.29-35. ISSN 0303-3295.

Summary Background. To determine central venous catheter related infection (IRcat) in carriers of central venous catheter (CVC) is of vital importance in order to avoid unnecessary removal of CVC. Objectives. 1. to determine the frequency of the removed CVC because of suspicion of IRcat (not confirmed). 2. to identify clinical factors that improve IRcat diagnose. Methods. The observational study was conducted from May, 1 to September, 30, 2003 at the Nephrology Department (Hospital de Clínicas). The inclusion criteria were as follow: patients of the Nephrology Department over 18 years old who underwent an hemodialysis CVC. Results. One hundred and seven consecutive patients carriers of CVC were enrolled in the study: 50 CVC (46.7%) were removed because of infectious causes and the left 57 (53.3%) due to other causes. The first group was divided in two: a) removed CVC with subsequent IRcat, n = 22 (44%); and b) removed CVC without IRcat, n = 28 (56%). A 20-variable comparison using an univariated analysis was done: a 14-day CVC was associated with temperature corresponding to IRcat (p = 0.02, OR = 2.1, IC 95% = 1.2-3.7). Conclusions. Fifty six percent (56%) of hemodialysis CVC removed because of infectious causes were not confirmed as infection process. A 14-day CVC was associated with IRcat in the cases of infection process.
