OBJECTIVES: To determine the feasibility of using a novel inhaled analgesic agent (Penthrox(TM) , methoxyflurane)) for transrectal ultrasonography (TRUS)-guided biopsies of the prostate.
PATIENTS AND METHODS: Patients undergoing TRUS-guided biopsies were each given a Penthrox inhaler to self-administer during the procedure and instructed in its use. Immediately after the procedure, patients were asked to rate their pain using a verbal rating scale from 0 to 10.
RESULTS: In all, 42 consecutive men underwent a TRUS-guided biopsy. The median pain score was 3. All 42 patients stated they would be happy to undergo the same procedure again. The only adverse effects reported by patients were brief light-headedness and a sickly sweet taste.
CONCLUSION: This study of our initial experience using Penthrox suggests that it may have a role in analgesia for TRUS-guided biopsy. It may provide safe, adequate analgesia that is easy for urologists to use and avoids excessive use of resources. Planning for a randomised control trial comparing Penthrox to the current 'gold standard' of prostatic infiltration of local anaesthetic is presently underway.
