Experience with sacral block regional anesthesia for greenlight photoselective vaporization of prostate

Objective: To explore the effect of appropriate local anesthesia in the greenlight photoselective vaporization of prostate（PVP） on the high-risk patients with benign prostatic hyperplasia（BPH）. Methods: A total of 56 high-risk patients with BPH were examined in this study.We carried out PVP in 55 of them under sacral block regional anesthesia with lignocaine chloride.Patient discomfort level during each block was assessed using pain grade questionnaire. Results: We had perfect pain control in the majority of the patients except that one patient required conversion to epidural anesthesia.Patients’ acceptance was very high.The anesthetic beginning effect time was 5min of 22 patients,10min of 29 patients and 15min of 4 patients,respectively.The anesthetic duration time was 60 min of 38 patients and 60-180 min of 17 patients.The anesthesia satisfactory with pain grade 0, I and II was 48 patients,5 patients and 2 patients,respectively.Only four patients had sligh dizzy,panicky and tinnitus,no other complication of the anesthetic procedure occurred. Conclusion: It is concluded that caudal anesthesia with 2% lignocaine chloride gives adequate anesthesia for greenlight photoselective vaporization resection of the prostate gland.We believe that ours is a simple,safe and effective procedure.
