RESUMEN
Venous canalization can be one of the most frequent causes of accidents due to an accidental puncture. To carry out activities which serve to lessen these misfortunes, bearing high biological risk, should become a priority for sanitary institutions and for their professionals. Inside a global strategy which deals with this aspect and with the objective of evaluating the convenience these instruments have in our center the authors made a practical evaluation on a series of them to discover their technical viability and their subjective consideration by professionals who employ them. For motives related to the practices of the ward in which this research took place, an emergency ward, the authors intentionally chose two passive instruments, available on the market, and three nurses who received 120 sample security catheters, 60 each for products A and B, to carry out habitual clinical practices, alongside a pad of paper on which to record any incidents. Regarding instrument A, 30 incidents, 52.6%, were detected while 37 sample procedures occurred. Regarding instrument B, 4 incidents, 7.01%, were detected while 47 sample procedures occurred. In absolute terms, neither of the two instruments demonstrated problems of an insecure manner; which is to say neither produced a situation related to the appearance of mis fortunate incidents associated to accidental punctures. The lower number of incidents with instrument B appears to be related to the habitual use of a conventional cathetec not a security one, produced by the same manufacturer in our center This research project was subsidized by the Sanitary Research Fund, PI 051265.
