<qa>  What is the second type of anesthesia?You are being asked to join the study because you have early stage prostate cancer and will have your prostate removed. The purpose of this study is to compare blood loss during surgery among two types of anesthesia. One type is general anesthesia. It puts you in a deep enough sleep that you will not feel anything. It also keeps your blood pressure low, which might decrease bleeding. The second type is combined spinal-epidural anesthesia. For this type, a small catheter is placed in your spinal canal through your back. Anesthesia given through the catheter makes your body numb from the waist down, so the sleep you would be in is not so deep. Your blood pressure would remain in your normal range. After surgery, the catheter remains in place to treat your pain, but your body would not be numb. When you wake up after general anesthesia, you would receive pain medicine through a vein in your arm.
