Administração de Heparina Intravenosa em Acesso Venoso Periférico: prática baseada na prevenção de eventos hemorrágicos

Abstract The aim of the study was to associate the occurrenc e and severity of hemorrhagic events with infusion devices used in anticoagulated patients with sodium heparin. It is a retrospective cohort study, performed by medical record analysis. Data collection took place in 2014 and 867 medical records of two intensive and one semi-intensive uni ts of a public university hospital in Rio de Janeiro were investig ated. The Bleeding Academic Research Consortium (BA RC) scale was used to evaluate the hemorrhagic event severity, an d to associate the hemorrhagic event occurrence wit h intravenous devices, the relative risk (RR) was calculated. In the study, the hemorrhagic event rate was 21.5% (CI = 13.5-31.5). Patients with peripheral venous access presented a 1.35 times greater risk of bleeding in the skin whe n compared to patients with central venous access. Patients with central venous access, already presented 1.29 times more risk of bleeding at puncture site when compared to patients with peripheral access. It is suggested that hepar in is primarily infused with peripheral venous access, since the co mplications resulting from hemorrhagic events at th e puncture site are more severe when compared to hemorrhagic skin e vents.
