西部落：你的外科医生怎么准备大型手术（在线收听）

Y:Hey,Don.Did you have wanna be a doctor when you are a kid?

D:Yeah,I always wanna be a surgeon.

Y:So,what happend?

D:I'm afraid of blood.Plus,it’s a lot of pressure, having someone’s life in your hands. I mean one mistake and you can kill someone.

Y:Right.But you know there are things surgeons can do to cut down on mistakes. Like, for instance, warming up before operating.

D:You mean warming up by as streching or something?

Y:Not exactly,but sort of.Most of the time, surgeons prepare for surgery by going over the case and thinking about the procedure. But studies have shown that warming up by actually practicing the procedure or going through the hand motions of the surgery really helps.In one study, doctors that warmed up this way had eighty-percent fewer errors than doctors who didn’t warm up.

D:Wow,so how can the surgeons practiced on a computer simulator or something?

Y:Exactly.And many hospitals have simulators, but they’re usually tucked away in a classroom or in the basement. But if there were a practice simulator near the OR, more surgeons could take a few minutes to warm up and perform better during the real thing.

D:Cool,if I'd known about this,maybe I would have to become a surgeon.

Y:Maybe.
