Prostate brachytherapy under hypnosedation: A prospective evaluation.

ABSTRACT

PURPOSE: Hypnosedation (HS) for brachytherapy has been proposed in patients with prostate cancer and has been evaluated. MATERIALS AND METHODS: 79 patients were treated with brachytherapy under HS. The Visual Analog Scale questionnaire was used to assess comfort and anxiety and the lowest, mean, and highest level of pain. Data for 79 patients who underwent general anesthesia (GA) and 37 patients who underwent spinal anesthesia (SA) treated at the same period were compared with HS group in terms of medication and treatment duration. RESULTS: 11 patients (13.9%) requested a GA, because they did not reach the hypnotic level. For the remaining 68 patients, the mean pain and comfort scores evaluated just after the intervention were 3.1 and 7.4, respectively. At 8 weeks, the scores were 2.8 and 7.5, respectively. 66 patients (97%) would choose this approach again and recommend it to other patients. The patients in the HS group received significant less medications than in the GA (remifentanil, propofol, kétamine, phenylephrine, ephedrine…) or SA (sufentanil, midazolam, morphine, bupivacaine…) groups with mean values of 3.1 vs. 7.9 vs. 5.6 (p < 0.0001), respectively. HS increased the mean time of surgery room occupation by 12 min vs. GA and by 20 min vs. SA. However, the recovery room occupation is avoided with HS (GA = 61 min and SA = 67 min) and a shorter duration of a need for a urinary catheter was noted. CONCLUSIONS: HS is a feasible and comfortable method of anesthesia and a good alternative to GA and SA for patients undergoing prostate brachytherapy, with reduced treatment duration and number of medications.
