Transurethral vaporization of the prostate is a new method of electrosurgery used for treating benign prostatic hypertrophy. We observed simultaneous obturator nerve stimulation during spinal anesthesia while the middle lobe of the prostate was being resected.

Temporary transcutaneous pacing thresholds were measured in 10 patients undergoing primary coronary artery bypass grafting (CABG) operations and 10 patients having reoperative CABG operations 7 months to 14 years after their previous cardiac surgery. All surgeries were performed via median sternotomy. After anesthetic induction using either fentanyl or sufentanil in combination with enflurane, the pacing stimulation thresholds were determined.
