Abstract
Objective To analyze the concept of fluid overload in Chronic Kidney Disease patients undergoing dialysis therapy and comparing it to the Nursing Diagnosis of Excess fluid volume present in the NANDA International. Method An integrative literature review carried out in the LILACS, CINAHL and SCOPUS databases. Results The sample was comprised of 22 articles. The defining attributes of the concept were: fluid retention, fluid buildup in the body, and weight gain over a short period; while the attributes composing the definition were: fluid retention in the body (intracellular/extracellular space) expressed by weight gain over short period of time. Twenty-one (21) antecedents and 22 consequents of fluid overload in patients with renal disease in dialysis therapy were identified. Conclusion The definition evidenced by the NANDA International taxonomy for the Excess fluid volume Nursing Diagnosis and the components of this diagnosis need to be complemented in order to better target the care of patients with kidney disease undergoing dialysis therapy.
Highlights
The nursing diagnosis Excess fluid volume, classified by the NANDA International in the domain of nutrition and class of hydration(1), was identified in 82% of terminal Chronic Kidney Disease patients undergoing hemodialysis in a study on the subject, representing a high prevalence of this problem among these subjects(2)
It is necessary to confirm the relationship between the characteristics not considered as being significant for Excess fluid volume in Chronic Kidney Disease patients undergoing dialysis, as well as to identify whether there are other components in addition to those presented by NANDA International
The concept of fluid overload was selected in the first step as it represents the conceptual core and the judgment element related to the nursing diagnosis of Excess fluid volume
Summary
The nursing diagnosis Excess fluid volume, classified by the NANDA International in the domain of nutrition and class of hydration(1), was identified in 82% of terminal Chronic Kidney Disease patients undergoing hemodialysis in a study on the subject, representing a high prevalence of this problem among these subjects(2). Another study states that the indicators azotemia, a decrease in hematocrit, a decrease in hemoglobin and anxiety are not accurate for establishing the diagnosis of Excess fluid volume in dialysis patients(3), despite being included in the taxonomy of NANDA International for this diagnosis(1). In this sense, it is necessary to confirm the relationship between the characteristics not considered as being significant for Excess fluid volume in Chronic Kidney Disease patients undergoing dialysis, as well as to identify whether there are other components in addition to those presented by NANDA International. The exhaustive analysis of some concept for any potential diagnosis, intervention or nursing result facilitates the taxonomic work, providing a strong evidence base(5)
