Randomized Controlled Trial Comparative Study Clinical TrialNitrous oxide vs periprostatic nerve block with 1% lidocaine during transrectal ultrasound guided biopsy of the prostate: a prospective, randomized, controlled trial.
We compared the efficacy of Entonox (BOC Gases, Manchester, United Kingdom), a mixture of 50% nitrous oxide and oxygen, with periprostatic infiltration of 1% lidocaine to provide analgesia during transrectal ultrasound (TRUS) guided biopsy of the prostate. ⋯ Inhalation of Entonox or periprostatic infiltration with 1% lidocaine can be used for analgesia during TRUS guided biopsy of the prostate since each provides significant and similar pain relief.
