ABSTRACT Objective: to validate the content of a Standard Operational Procedure, regarding nursing interventions in emergency patients treated with vasoactive drugs. Method: methodological study, carried out from December 2015 to January 2016. Content validity was determined by 16 experts (13 nurses, 2 pharmacists and one biomedical scientist), who judged it through a four-point Likert scale. The items were evaluated in terms of: feasibility, objectivity, simplicity, clearness, pertinence and accuracy. The Content Validity Index was applied, accepting the value ≥ 0.90. Results: two rounds of evaluation were required to achieve the minimum index. The items were reviewed regarding writing, dilution, indication and replacement interval. The instrument was validated with 33 items and with total Content Validity Index of 0.99. Conclusion: the instrument was considered appropriate, fractionally and globally, for nursing care for the patient treated with vasoactive drugs in emergency, in a safe and reliable way.
