Pre-0p today...surgery 1 week from today Hi everyone. I had my pre-op today at Frankilin Regional in Louisburg. Wow...took 3 hours and I had one unwanted suprise. Apparently, the anestheseologist makes all the GPS patients get an artierial catheter to continously monitor your bp during surgery. YIKES!!!! Sounds pretty painful. Other than that everything went well and I'm ready to go next Thursday jan 31..
