Spinal Clonidine Fails to Provide Surgical Anesthesia for Transurethral Resection of Prostate: A Dose-Finding Pilot Study

Abstract

Subarachnoid clonidine cannot be reliably used as the sole agent for spinal anesthesia, since general anesthesia is often required or deep sedation occurs. Increasing doses of clonidine do not prolong postoperative analgesia. Thus, clonidine could be used as a spinal analgesic but not as a spinal anesthetic.
