Summary

Intravenous diazepam effectively managed panic attacks during MRI scans in 46 patients, allowing study completion without adverse effects. Patients were willing to undergo repeat MRI scans if needed.

Area of Science:

  • Radiology
  • Pharmacology
  • Psychiatry

Background:

  • Magnetic Resonance (MR) imaging is a crucial diagnostic tool.
  • Patient anxiety and panic attacks can impede MR imaging completion.
  • Sedation protocols are often necessary but can have side effects.

Purpose of the Study:

  • To evaluate the efficacy and safety of intravenous diazepam for managing panic attacks during MR imaging.
  • To determine if diazepam administration prevents the need for sedation cessation.
  • To assess patient willingness for repeat MR examinations after diazepam intervention.

Main Methods:

  • 3000 conscious patients without specific comorbidities were enrolled.
  • 46 subjects experiencing panic attacks during MR imaging received IV bolus diazepam.
  • Adverse effects and study completion rates were monitored.

Main Results:

  • Diazepam successfully resolved panic attacks in all 46 affected patients, enabling examination completion.
  • No expected side effects of diazepam, such as somnolence or respiratory depression, were observed.
  • Patients reported rapid relief from panic symptoms and agreed to repeat MR scans if necessary.

Conclusions:

  • Intravenous diazepam is a safe and effective intervention for managing acute panic attacks during MR imaging.
  • This approach facilitates the completion of essential diagnostic imaging in anxious patients.
  • Diazepam may offer a favorable risk-benefit profile compared to other sedatives for this indication.
