The use of a short-acting benzodiazepine to reduce the risk of syncopal episodes during upright stereotactic breast biopsy

The use of sublingual lorazepam provides a safe and effective means of reducing the risk of syncopal episodes during upright stereotactic breast biopsy. Sublingual lorazepam, 2-4 mg, was received by 19 women undergoing a total of 20 stereotactic procedures.

All 4 women who received lorazepam for significant anxiety had successful biopsies. Stereotactic guided wire localization also was performed in 2 cases
