摘要
Objective To prospectively compare two local anaesthetic techniques for prostatic biopsies, which are usually taken with no anaesthesia; because multiple biopsy techniques are becoming more common and there is an increasing need for analgesia/anaesthesia during the procedure. Patients and methods The study group comprised 86 consecutive men (median age 67.7 years) undergoing prostatic biopsy because of either an abnormality of prostate specific antigen level or digital rectal examination. They were randomized into four groups; men in group 1 received 10 mL of 1% lignocaine infiltrated into the periprostatic nerve plexus bilaterally; men in group 2 received 11 mL of 2% lignocaine gel rectally; men in groups 3 and 4 were recruited as controls, and given either plain gel rectally or an injection with saline into the periprostatic nerve plexus. Sextant prostate biopsies were taken in all cases using a standardized protocol. Immediately after the procedure patients were asked to indicate the degree of pain on a 10-cm visual analogue scale. Results Men in group 1 had significantly less pain than the others (P < 0.001). There was no statistically significant difference in pain between men who received plain gel rectally or saline injection (P = 0.35). The rectal instillation of 2% lignocaine gel did not reduce pain significantly (P = 0.186) compared with the controls. Conclusion A periprostatic nerve block with 1% lignocaine was associated with significantly less pain during prostatic biopsy than was rectal lignocaine gel or placebo.
