MOLINA MEJIAS, Patricia et al. Contribution of the ultrasound performed by nursing to the exploration of vascular access. Enferm Nefrol [online]. 2017, vol.20, n.3, pp.241-245. ISSN 2255-3517.  https://dx.doi.org/10.4321/s2254-28842017000300007.

In recent years, vascular ultrasound has been used in nursing dialysis units, improving knowledge of vascular access (VA), helping in the selection of cannulation zones and increasing confidence in new or difficult VAs.

Our objective is to describe the reasons for the exploration of VA with ultrasound, the findings found and contrast them with the radiology service.

It is an observational, descriptive study in 22 patients with arteriovenous fistula (AVF). We designed a graph where data from ultrasound scans were collected and exploited with SPSS15.

The sample consisted of 22 patients. There were 37 explorations. The main causes of the exploration were mainly difficulty or pain in the punctures followed by the localization of new areas of puncture, previous extravasations, surveillance in the maturation of AVF and follow-up of AVF. We found 35.1% with thrombi, 8.1% collateral circulation, 5.4% collections / hematomas and 13.5% stenosis. Of the 22 patients, 6 were referred to radiology and 2 stenosis, 1 decrease of flow and 1 thrombus were tested.

A high number of ultrasound examinations by nursing are carried out autonomously with which AV dysfunctions are identified, contributing more information about AV.
