| The Making of a Surgeon How does a doctor recognize the point in time when he is finally a "surgeon"? As my year as chief resident (进修医生) drew to a close, I asked myself this question 1 more than one occasion. The answer, I concluded, was 2 .When you can say to yourself, "There is no surgical patient I cannot treat competently, treat just 3 or better than any other surgeon"- then, and not until then, you are 4 a surgeon. I was 5 that point. 6 , for example, the emergency situations that we met almost every night. The first few months of the year I had 7 the ringing of the telephone. I knew it meant another critical decision to be 8 .Often, after I had told Walt or Larry what to do in a particular 9 , I'd have trouble getting back to sleep. I'd 10 all the facts of the case and, often, wonder 11 I had made a poor decision. More than once at two or three in the 12 , after lying awake for an hour, I'd get out of 13 , dress and drive to the hospital to see the patient myself. It was the only 14 I could find the 15 of mind I needed to relax. Now, in the last month of my residency, 16 was no longer a problem. Sometimes I still couldn't be sure of my decision, but I had learned to 17 this as a constant problem for a surgeon. I knew that with my knowledge and experience, any decision I'd made was bound to be a 18 one. It was a nice feeling. This all sounds conceited (自负的) and I guess it is - 19 a surgeon needs conceit. He needs it to encourage him in trying moments when he's bothered by the 20 and uncertainties that are part of the practice of medicine. He has to feel that he's as good as and probably better than any other surgeon in the world. Call it conceit -call it self-confidence; whatever it was, I had it. | ||||
