[Risk for vascular trauma: diagnosis proposal and validation by experts]

This concept and content validation study aimed to compose the title, vulnerability mechanisms and risk factors for the nursing diagnosis 'Risk for Vascular Trauma', according to the taxonomy proposed by NANDA, as well as to validate the elements of this diagnosis, based on 60 experts' opinion. Fifty-one factors were identified, related to five axes: medication and infusion form/periodicity; intravascular catheter and dwelling in the same site; fixation of the intravascular catheter; individuals, their habits, communication standard, lifestyle and sensory-motor ability; and professional decisions, institutional policy and procedures. Among these, 28 vulnerability factors were identified (score > 0.80). The results evidenced that 'Risk for Vascular Trauma' is a new nursing diagnosis, and its clinical validation is suggested.
