Fracaso y punción múltiple en la colocación de catéteres para hemodiálisis en un hospital escuela

Objective: To determine the incidence of influent factors in failure and multiple punctures for the placement of central venous catheter for hemodialysis (CVCHD). Methods: A descriptive analytical study, patients with hemodialysis requirements from February to October 2014 were included. Nurses of the vascular access clinic recorder clinical characteristics, as well as the number of necessary punctures, fail to place the CVCHD and its immediate complications. The analysis of the data was done with descriptive and inferential statistics as corresponded; multiple logistic regression was done. Results: 180 procedures were analyzed, of which 170 hemodialysis catheters (94.4%) were able to be placed. The failure of the CVCHD placement was more frequent in patients with a previous catheter history with an OR 1.46 (95% CI 1.03 - 2.05). Obesity was the only Conclusions: There was an increased risk of failure with a history of previous catheters and the obesity was associated with the need
