The vast majority of the time, we do not leave the operating room during procedures to use the restroom, eat or take any breaks. The ability to withstand long periods of time in the operating room comes with our years of surgical training. We are used to being in the operating room for many hours at a time. When we are operating, we feel very focused. We are able to tune out everything else besides the procedure at hand. At the end of an operation, that is when we will realize we feel hungry or tired. Until the surgery is over, we are in the zone.
