BRAZALET TEJERINA, Mónica et al. Comparative study of safety needles and non-safety needles. Rev Soc Esp Enferm Nefrol [online]. 2008, vol.11, n.4, pp.265-270. ISSN 1139-1375.

The daily practice of nurses working in haemodialysis involves risks such as accidental injections, with the consequent risk of contact with biological agents. Accordingly, the highest possible number of tools with safety devices should be used. Our aim was to evaluate the possible differences between needles fitted with safety devices and needles which did not have such devices in the puncture of arteriovenous fistulas. We carried out an experimental prospective study with 42 patients who had antologous fistulas. A register was created of data relating to the "patient", the "professional" and the "material" in order to evaluate differences between the two different types of needle. A total of 35 patients were analysed over 455 sessions. There were no significant differences in the use or not of the safety device with regard to the pain caused, blood flow, venous pressure or bleeding on puncture. Of 910 injections with safety needles, the device jammed on 24 occasions.
