RESUMO
OBJECTIVES: during peripheral venipuncture, health professionals are recommended to use a tourniquet above the puncture site in order to potentiate venous distension. Given its characteristics and use in clinical settings, tourniquets may represent a source of microorganism dissemination. However, the results of scientific studies in this area are scattered in the literature. This scoping review aims to map the available evidence on health professionals' practices related with tourniquet use during peripheral venipuncture and associated microbiological contamination. METHODS: scoping review following the Joanna Briggs Institute methodology. Two independent reviewers analyzed the relevance of the studies, extracted and synthesized data. RESULTS: fifteen studies were included in the review. Overall, tourniquets were reused without being subject to recurring decontamination processes. It has been found that practitioners share these devices among themselves and use them successively for periods between two weeks and seven and half years. CONCLUSION: nursing practices related to tourniquet use during peripheral venipuncture are not standard. Reuse of tourniquets may jeopardize the patient's safety if reprocessing (cleaning and disinfection/sterilization) is not adequate, given the type of tourniquet material and microbiota found. New studies are needed to assess the impact of various types of reprocessing practices on tourniquet decontamination and patient safety.

Se realizó la medición de seis torniquetes neumáticos de presión del Hospital ABC por espacio de 30 días dos veces al día, una previa y una posterior a su empleo en procedimientos quirúrgicos, obteniéndose de esa manera 360 mediciones en total (60 por cada aparato de isquemia). Se obtuvieron variaciones de las presiones entre -8.3 mmHg como valor más bajo hasta + 11.41 mmHg el más alto, predominando las mediciones de menos mmHg, las cuales son las más peligrosas, por lo que se recomienda la calibración de los torniquetes neumáticos antes de su uso clínico y después de su uso por espacio de 90 o más minutos
