Self-Administered Nitrous Oxide (SANO) During Transrectal Prostate Biopsy to Reduce Patient Anxiety and Pain

Summary

Transrectal prostate biopsy is a commonly performed ambulatory procedure for diagnosing prostate cancer. Prostate biopsy are associated with pain or anxiety. Nitrous oxide (or laughing gas) is a well-known inhaled anesthetic which is frequently used in dental offices and for pediatric procedures to alleviate a patient's anxiety and pain. This study seeks to determine whether administration of nitrous oxide at the time of prostate biopsy will improve a patient's experience of care.
