Definições operacionais das características definidoras do diagnóstico de enfermagem Volume de Líquidos Excessivo

Abstract

As definições operacionais são requisitos importantes no ensino da Semiologia e Semiotécnica nos Cursos de Graduação e Pós-Graduação em Enfermagem. Este estudo descritivo, acerca das definições operacionais elaboradas para as características definidoras do diagnóstico de enfermagem Volume de Líquidos Excessivo em portadores de cardiopatias foi realizado a partir de revisão da literatura, no período de 1985 a 2001. As definições operacionais foram analisadas criticamente por quatro enfermeiros especialistas em diferentes campos clínicos de atuação. Após os ajustes sugeridos por esses especialistas, os dados foram enviados a uma consultora técnica, para avaliação conclusiva.

Excess fluid volume: clinical validation in patients with decompensated heart failure

“…In an exploratory and descriptive study developed at an institution specialized in patients with cardiovascular diseases, the researchers attempted to detect 61 nurses' use of and importance attributed to the defining characteristics of the diagnosis Excess Fluid Volume. Hepatojugular reflex scored high in the importance category, with 3.89 on a scale ranging from 1 to 5 points (21) . In that research, the important relation between hepatojugular reflex and the Excess…”

“…The findings of this physical examination method can be extremely useful in clinical practice, as it is a feasible and low-cost means to support the assessment of hemodynamic conditions, especially in critical patients (24) . In a study of a group of cardiovascular patients, in which nurses detected the use and importance granted to the defining characteristics of the diagnosis Excess Fluid Volume, it was verified that increased central venous pressure figures among aboveaverage characteristics, scoring 3.84 (21) . In another study, central venous pressure variations were defined as one of the minor defining characteristics, identified in 55.5% of patients diagnosed with Excess Fluid Volume by expert 1 and in 66.6% of patients by expert 2 (23) .…”

“…In this context, a research assessed mortality during one year in patients hospitalized with acute HF and the authors demonstrated that pulmonary congestion was the most common symptom in the sample, present in 63.5% of cases assessed (22) . In the results of a study performed at an institution specialized in cardiovascular patients, the nurses who participated in the study described pulmonary congestion with above-average scores in the category 'use of defining characteristics', corresponding to 4.35 on a scale from 1 to 5 points (21) . Besides, in a content validation study of this nursing diagnosis, it was observed that this was one of the primary characteristics (17) .…”

Prevalence of nursing diagnosis of fluid volume excess in patients undergoing hemodialysis

“…We used a questionnaire as an instrument of data collection, it was developed according to the defining characteristics present in the nursing diagnosis of fluid volume excess -NANDA International -supported by the literature, which contained the operational and conceptual definitions of each characteristic, in order to facilitate the instrument construction (13)(14) . This instrument had opened and closed questions, divided into: sociodemographic and clinical data, data from general physical examination, and laboratory tests of segments.…”
