title: [Analgesic effect of oral tramadol on transrectal ultrasound-guided needle biopsy of the prostate in a randomized double-blind study].
abstract: A total of 121 Japanese patients scheduled for prostate biopsy were randomly and double-blindly assigned to be given a single oral dose of 100 mg Tramadol mixed with 20 ml of sugar syrup or placebo, 30 minutes before the procedure. Pain severity was measured by verbal rating scale (VRS) and visual analog scales (VAS). We also analyzed cardio-respiratory parameters and complications. Of 121 patients, 117 replied validly to VRS and VAS ; and 91 of 117 patients replied to the cohort questionnaire for analysis of the late disorder, patient's impression, prolonged pain and past history of hemorrhoid treatment. Tramadol showed no significant effect on pain severity indicated by VRS and VAS, and no change in cardiorespiratory parameters. Furthermore, 70 patients without a history of hemorrhoid treatment, showed no significant analgesic benefits of Tramadol during the biopsy. In total, 3 patients had side effects of vomiting (CTCAE : grade 1)6), which subsided spontaneously. The oral administration of a single dose of 100 mg Tramadol 30 minutes before a transrectal needle biopsy of the prostate was safe, but was not effective to calm down the pain severity.
