espanolEn los ultimos anos, ha comenzado a usarse por parte de enfermeria la ecografia vascular en las unidades de dialisis, mejorando el conocimiento del acceso vascular (AV), ayudando en la eleccion de las zonas de canulacion y aumentando la confianza en los AV nuevos o dificultosos. Nuestro objetivo es describir los motivos de exploracion del AV con ecografo, los hallazgos encontrados y contrastarlos con el servicio de radiologia. Es un estudio observacional, descriptivo en 22 pacientes con fistula arteriovenosa (FAV). Disenamos un registro donde se recogieron los datos de las exploraciones ecograficas y se explotaron con el programa SPSS15. Se realizaron 37 exploraciones en 22 pacientes. Las principales causas de la exploracion fueron: dificultad o dolor en las punciones, localizacion de nuevas zonas de puncion, extravasaciones previas, vigilancia en la maduracion de la FAV y seguimiento de FAV. Hallamos 35.1% con trombos, 8.1% circulacion colateral, 5.4% colecciones/hematomas y 13.5% estenosis. De los 22 pacientes, 6 se derivaron a radiologia y se contrastaron 2 estenosis, 1 disminucion de flujo y 1 trombo. Las exploraciones ecograficas realizadas por enfermeria de forma autonoma se identifican disfunciones del AV aportandonos mayor informacion sobre el AV. EnglishIn 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.
