Intrathecal fentanyl added to hyperbaric ropivacaine for transurethral resection of the prostate

Abstract

Addition of fentanyl 25 microg to hyperbaric ropivacaine 18 mg for spinal anesthesia in patients undergoing TURP may significantly improve the quality and prolong the duration of analgesia, without causing a substantial increase in the frequency of major side-effects.
