Processo de punção de vasos e trauma vascular periférico em uma unidade de pronto atendimento

Abstract

Introduction: The use of blood vessels, despite being recognized as useful and beneficial to clinical practice, can cause iatrogenic, adverse effects and compromise the safety, treatment and comfort of the users. The manifestations of change in the insertion site of the peripheral intravascular catheters or adjacent areas are known as vascular trauma. Objectives: to produce light-hard assistance technology in the bundle modality to support the implementation of nursing interventions on the peripheral vessel puncture process and prevent the vascular trauma in an Emergency Department (ED) based on a situational diagnosis, with a view to the structuring of evidence-based nursing care. Methods and techniques: Reference was made to: 1) Public Policies in Emergency; 2) Procedure of puncture of peripheral vessels in a UPA; 3) Theory of Social Representations (Abric) and 4) Theory of Neuman. Mixed-method research, operationalized in sequential and simultaneous procedures using complex interventions, according to the Medical Research Council (MRC). Scenario: UPA of size III in Minas Gerais. There were methodological steps: Development (integrative review, ambience, field diary, structural approach to social representations); Reliability and Piloting (cohort and field diary); Evaluation (bundle construction, educational process and field diary) and Implementation (permanent education with segment and monitoring and field diary). Participants were 56 members of the nursing team and 228 users of the Sistema ùnico de Saúde (SUS) who had their punctured veins evaluated in a cohort (252). Data collected by triangulation of techniques and methods (semiological, photographic, interviews, projective techniques, participatory observation and electronic collection) with the support of the Open Data Kit (ODK), EVOC 2000® and SPSS24® programs were used, and ethical/legal research requirements involving human beings were met. Results: users presented as: men (58.3%), with low schooling (56.8%), elderly (55.6%) and allocated in the yellow sector (67.1%); incidence of peripheral vascular trauma of 62.3% (predominantly enduring, edema and pain) documented by imaging criteria. There was a correlation (p-value = 0.001-0.040) between sex, age, hypertension, visible blood and self-evaluation of having a difficult-to-puncture vein with outcome variable (vascular trauma). Light-hard care technology was developed in bundle modality, based on situational diagnosis and scientific evidence. Technological / communicational and didactic-pedagogical tools (video and protocol) were used to subsidize individual and group approaches. The integrative review delineated collections on types/causes of vascular trauma and interventions compatible with ED users, explaining modifiable/non-modifiable profiles by nursing interventions. Symbolic elements portrayed human responses from users and practitioners who drive care demands and gaps in the perception of how they conceive, confront, value, experience, and deal with the issue. Collective conception of professionals based on a fragmented technique disconnected from the sensitive and singular dialogical relationship that should preside any professional act. Conclusions / final considerations: the complexity of this issue and the distance of the nurses from their role in directing the nursing staff and assisting/management activities made it possible to deny the hypothesis of nullity of H1 and the hypothesis of nullity of H2. Contributions were: situational diagnosis, bundle creation and educational approach. It is recommended: institutional investment in continuing education of the nursing team and appropriate materials, creation of an institutional protocol for reporting adverse events and completion of a cohort after the implementation of the bundle and replication of this research in other EDs.
