Comparison of two intravenous sedation techniques for percutaneous radio frequency trigeminal rhizotomy. A pilot study.
Conscious sedation, as used in dentistry and oral surgery, has been used satisfactorily to manage patients undergoing the intense pain encountered in radio frequency trigeminal rhizotomy for tic douloureux. The pain produced by this procedure cannot be blocked by local anesthesia. General anesthesia cannot be used because of the need for sensory testing in an awake, cooperative patient. Conscious sedation using alphaprodine, hydroxyzine, methohexital, and intensive behavioral modification was compared with a neuroleptic intravenous sedation technique using droperidol, fentanyl, and thiopental. Patients managed with conscious sedation were found to be more amnestic for the pain of surgery, a difference that persisted six months later.
