科学美国人60秒听力练习：短袖不能阻挡细菌

科学美国人60秒英文文本

Good news for chilly doctors—you can wear long sleeves with impunity inside hospitals. Because University of Colorado researchers find that docs pick up just as much bacteria when their forearms are bare as they do when wearing long sleeves. The study is in the Journal of Hospital Medicine. [M. Burden et al., Cleaned Physician Uniforms and Infrequently Washed White Coats Have Similar Rates of Bacterial Contamination After an Eight-Hour Workday: A Randomized Controlled Trial]

Britain recently issued guidelines that banned white coats and long sleeves in hospitals in the hope that the move would decrease the chances of picking up and transferring bacteria, especially the scourge of MRSA: methicillin-resistant staph. The research team wanted to see if the rule would actually help. They had 50 doctors start a workday wearing a freshly washed short-sleeve shirt and another 50 in their unwashed long-sleeved white coats.

Samples were taken from all 100 docs, at the wrists, pockets and cuffs, if they had them. And by the end of an eight-hour shift, both groups of physicians were carrying similar bacteria loads. In fact, after just three hours the short-sleeved docs were already hosting half of the bacteria as the docs wearing unwashed coats. So go ahead and wear long sleeves in the hospital. If you’re going to wash something, make it your hands.

科学美国人60秒中文翻译：

医院里一些怕冷的医生而言，有一条好消息——可以在医院里穿长袖服了，不用担心受到惩罚。因为科罗拉多大学的科学家发现，即便把前臂裸露出来，带上细菌的数量也和穿长袖服一样多。这一研究发表在了《医院医学杂志上》[M. Burden et al., "Cleaned Physician Uniforms and Infrequently Washed White Coats Have Similar Rates of Bacterial Contamination After an Eight-Hour Workday: A Randomized Controlled Trial," link to come]。

最近，英国公布的新大纲禁止在医院里穿白大褂和长袖服，希望这一举措能够降低以上带上细菌到处传播的几率，尤其是MRSA，也就是耐甲氧西林金黄色葡萄球菌。但是这一研究团队想看看这一新规是否真有用。于是，他们找到50名医生，他们每天穿着刚刚清洗过的短袖服工作，同时找来另外50名医生，则穿着没有清洗的长袖白大褂。

然后，对这100名医生的腕关节、口袋和袖口进行取样分析，看带有哪些细菌。试验结果发现，8小时过后，两个组的医生带有的细菌数量一样。实际上，3小时过后，穿短袖的医生带有的细菌数量，就已经是那些穿着未清洗衣服的医生带有数量的一半了。所以，大胆在医院里穿长袖服。非要清洗的话，注意把手洗干净。
