Brief Summary

1-hour Premedication for Allergy Goal in Emergency: PAGE-1 is a prospective, parallel, two-arm, non-inferiority, randomized controlled trial evaluating the safety of a 1-hour (intervention) versus a 4-hour (standard regimen) intravenous (IV) premedication protocol in adult patients in the Emergency Department (ED) with a documented iodinated contrast allergy and requiring computed tomography (CT) imaging for a high-risk indication.

Outcome Measures

Primary Outcomes (2)

  • Difference in proportion of Acute Contrast Reaction

    Measurement of any contrast reaction after contrast administration

    30 minutes

  • Proportion of patients eligible for intervention

    Ratio of those eligible to screened

    Before randomization

Secondary Outcomes (2)

  • Proportion randomized to intervention and control

    Within 30 minutes after completion of CT imaging

  • Adverse events after intervention

    Within 30 minutes after assessment of primary outcome

Study Arms (2)

1-hour Premedication Protocol

EXPERIMENTAL

IV glucocorticoid and antihistamine 1 hour before contrast

Other: IV glucocorticoid and antihistamine

4-hour Premedication Protocol

ACTIVE COMPARATOR

IV glucocorticoid 4 hours before contrast and IV antihistamine 1 hour before contrast

Other: IV glucocorticoid and antihistamine (standard of care)

Interventions

Methylprednisolone sodium succinate (e.g., Solu-Medrol®) 40 mg IV immediately 4 hours before contrast medium administration, plus diphenhydramine 25 mg IV 1 hour before contrast for CT imaging

4-hour Premedication Protocol

Methylprednisolone sodium succinate (e.g., Solu-Medrol®) 40 mg IV immediately plus diphenhydramine 25 mg IV 1 hour before contrast medium administration for CT imaging

1-hour Premedication Protocol
