Abstract：
The objective of this study was to operationally define the concept of success in peripheral intravenous catheterization in children considering the Walker and Avant model. This is a methodological study, carried out through the following steps: concept selection, the definition of the analysis objective, identification of possible uses of the concept, determination of critical or essential attributes, construction of a model and opposite case, and identification of antecedents and consequences. The study was carried out based on a search in international databases from January to March 2021. The sample consisted of 47 studies conducted in 17 countries between 2008 and 2021. Five attributes, 20 antecedents, 10 consequences, and an empirical reference of the studied concept were identified. Also, 2 cases, model and opposite, were elaborated, and an operational definition of the concept was developed. The Walker and Avant method enabled the operationalization of the concept of success of peripheral intravenous catheterization in children based on attributes, antecedents and consequents, and model and opposite cases.
摘要：
这项研究的目的是考虑Walker和Avant模型，在操作上定义儿童外周静脉导管插入成功的概念。这是一项方法论研究，通过以下步骤进行：概念选择，分析目标的定义，识别概念的可能用途，确定关键或基本属性，构建一个模型和相反的案例，以及前因后果的识别。这项研究是根据2021年1月至3月在国际数据库中的搜索进行的。该样本包括2008年至2021年在17个国家进行的47项研究。五个属性，20个先例，10个后果,并确定了所研究概念的实证参考。此外，2例,模型和相反，被详细阐述，并对该概念进行了操作定义。Walker和Avant方法使基于属性的儿童外周静脉导管插入成功的概念得以实施，前因后果，以及模型和相反的情况。
