- Construction and validation of a scale of assessment of self-care behaviours anticipatory to creation of arteriovenous fistulaPublication . Sousa, Clemente Neves; Figueiredo, Maria; Dias, Vanessa Filipa; Teles, Paulo; Apóstolo, João LuísAims and objectives. We developed a scale to assess the self-care behaviours developed by patients with end-stage renal disease to preserve the vascular network prior to construction of arteriovenous fistula. Background. The possibility of creation of an arteriovenous fistula depends on the existence of an arterial and venous network in good condition, namely the size and elasticity of the vessels. It is essential to teach the person to develop self-care behaviours for the preservation of the vascular network, regardless of the modality of dialysis selected.Design. Methodological study. Methods. The scale was developed based on clinical experience and research conducted by the researcher in the area of the vascular access for haemodialysis. The content of the scale was judged by two panels of experts for content validity. The revised version of the scale was administered to a convenience sample of 90 patients with end-stage renal disease. In the statistical analysis, we used the Cronbach’s alpha, the Kaiser–Meyer–Olkin and scree plot and the principal component analysis with varimax rotation. Results. A principal component analysis confirmed the univariate structure of the scale (KMO = 0 759, Bartlett’s sphericity test-approximate v2 142 201, p < 0 000). Cronbach’s a is 0 831, varying between 0 711–0 879. Conclusion. This scale revealed properties that allow its use to assess the patients self-care behaviours regarding the preservation of the vascular network. Relevance to clinical practice. This scale can be used to evaluate educational programmes for the development of self-care behaviours in the preservation of vascular network. This scale can identify not only the patients that are able to take care of their vascular network but also the proportion of patients who are not able to do it, that need to be educated.
- Physical examination: How to examine the arm with arteriovenous fistulaPublication . Sousa, Clemente Neves; Apóstolo, João Luís; Figueiredo, Maria; Martins, MM; Dias, Vanessa FilipaPhysical examination has demonstrated its effectiveness in identifying complications of arteriovenous fistula (AVF). It should be initiated at the stage prior to the construction of the AVF and continue in its accomplishment, maturation, and subsequent use in the treatment of hemodialysis. Nurses should incorporate the physical examination in their practices, in order to preserve the vascular net of patients and assist in the recognition of complications of AVF. It is intended to describe aspects of the physical examination that enable the identification of the AVF complications including: infection, accessory veins, venous stenosis, steal syndrome, high-output cardiac failure, and venous hypertension.
