Processo de punção de vasos periféricos em adultos: diversidade de experiências e representação social

Abstract

Abstract: Quanti-qualitative research whose methodological route intended to analyze the social representations of venipuncture among adults who have experienced the peripheral vessels puncture. Multiple methods and techniques were adopted. During the quantitative approach a survey research was conducted, while in the qualitative approach individual interviews were taken, applying the techniques of "cutting and pasting of comics" and "free recall". The application of these techniques aimed to capture intervening variables on the process of puncturing peripheral vessels and support the identification of elements and characterize the relevance of the social representation of this process. Data obtained from October 2012 to February 2013 through individually recorded interviews and field diary, both conducted in a hospital (regular hospitalization area) and in a program of renal replacement therapy. Sample selection complete. After applying the eligibility and exclusion criteria, there were 365 approaches for data collection, 235 people participated in the phase of the survey, of whom 120 were hospitalized, 75 were on hemodialysis and 40 collected blood samples. There was individualized approach and help to fill the questionnaire. Evocation technique applied in the interviews, with participation of 90 people, 30 of them hospitalized for blood collection or hemodialysis. With the inductive term appointed (process of vessel puncture). We obtained 444 words/expressions evoked to five of the requested. In applying the technique of "cutting and pasting of comics" and recording the explanatory discourse 60 people participated, 20 in each situation addressed. The same comics were shown to the participants of this step. A participant joined one or more techniques. For the treatment of the survey data, with descriptive analysis, was used the Statistical Package for Social Sciences (SPSS) version 20. Evocation data formed the corpus, consolidated in EVOC 2000 version, and were analyzed through the fourhouse board technique. The contents obtained by the technique of cutting and pasting the comics were consolidated into NVivo software version 10 and analyzed according to similarity of expressions. All information has been addressed with patterns of anonymity, using names of flowers, stones or colors. We met all ethical and legal requirements for research involving humans. In the survey phase participants profile predominated the participation of women in blood sample collection and men hospitalized or undergoing hemodialysis, with younger age among women who collected blood; predominance of skin declared as white (40%), less than nine years of education (65%), marital stability (55%) and children. As the process of vessel puncture is a technical/scientific procedure, users, however, interpret it in a particular way, featuring some steps over others. It was possible to identify the intervening variables (exposure to different situations and times of occurrence of vessels puncture processes) compared with the outcome variables, i.e., the feelings, perceptions and behaviors of the participants before the process of puncturing blood vessels. There was a modification of perceptions, feelings and behaviors throughout the stages of the process of vessels puncturing. In the period preceding the introduction of the needle inside the vessel there was a predominance of feelings of fear, discomfort, anxiety, indifference and normality and behaviors of

xxii silence, collaboration, normality and "being used to" were adopted, although accompanied by the nervousness of those people in hemodialysis. The length of the needle insertion was experienced with feelings of pain and discomfort and behaviors of collaboration, silence and nervousness, with occasional gaze deviation, not to follow the technical procedure performed. Maintaining the needle in the vessel predominantly generated feelings of limitation of movement and discomfort when the period was extended. There was also the behavior of collaboration. The feeling of relief and burning sensation were predominantly those who emerged during the removal of the catheter inside the vessel and the participants mentioned to adopt behaviors of collaboration and indifference to the removal. In the post-removal time predominated feelings of indifference, relief, normality and nothing and behaviors of silence and collaboration, showing the non-perception of this moment as a step of the process, except to people who underwent hemodialysis. The results showed that the structure of social representations of vessel puncture was composed by the central elements of pain and fear. The peripheral elements appeared insecurity, who punctures, professional skill, result, repuncturing and bleed, setting a neutral or negative approach expressed in different puncture situations that relied on experience, information, value judgment, conception of its purpose and sensory perception, what was reaffirmed by the technique of cutting and pasting. To capture the social representations through the feelings and behaviors, as well as knowledge, values, experiences of people own their vessels punctured for the purpose of blood collection, drug therapy or hemodialysis during puncture, allowed to reread the puncture of vessels. While a procedural activity, care demands showed up for which the nurse has opportunities to print educational guidelines, therapeutic and management actions and to capture/use evidences from the investigation. Answers of individuals were characterized for which the nurse is able to minimize negative feelings and behaviors and to encourage positive ways of coping. In proposing a quanti-qualitative approach, using multiple methods and techniques from a conceptual and methodological framework, this research proved to be enriching and creative and brought as its limitation the not comparison of the participants while groups that have peculiar experiences in the process of blood vessels puncturing.
