How dangerous could that laptop, desktop, or Mac sitting in front of you be?

    The first report to count computer-related emergency room injuries shows that each year more and more Americans are tripping over cords, dropping monitors, banging heads and snagging limbs.

    Emergency room visits from computer injuries increased sevenfold between 1994 and 2006, according to a report published June 9 in the American Journal of Preventive Medicine.

    The first report to count computer-related emergency room injuries shows that each year more and more Americans are tripping over cords, dropping monitors, banging heads and snagging limbs.

    Worse, the number of injuries outpaced the number of new computers in the home. While injuries jumped 732 percent, household computer ownership increased by just 309 percent.

    "The numbers look overwhelming but think about how in 2006 we had 115 million emergency room visits in the U.S., then visits from computers was 0.008 percent," said Dr. Charlene Irvin, of the American College of Emergency Physicians.

    Since this study was limited to only 100 hospitals, counting computers injuries from all hospitals would likely bump up that percentage. But Irvin doubts computer woes would ever make the top 10 list.

    While more common causes of emergency room visits such as gunshots and motor vehicle accidental injuries of course got more media attention, she was pleased to see information from external cause of injury codes （e-codes） used to document why people came into the emergency room. Irvin said only 17 states voluntarily submit e-codes.

    Indeed, the report highlighted details that are hard to come by in many emergency room statistics. For instance, computer equipment falling on a person caused more E.R. visits [21.1 percent] than did tripping or falling on the computer, [18.2 percent of visits]. Also, males were more 7 percent more likely to injure themselves on the computer than females.

    The data also showed head injuries increased until 2003, and then went on a decline. The authors guessed that the move to thinner LCD screens from the heavy, boxy cathode ray tube monitors had a safety benefit.

    "If a person comes into the ER and says 'I dropped a computer monitor on my foot,' they're not saying 'I dropped my LCD monitor on my foot' or 'I dropped my cathode ray tube computer monitor on my foot,'" McKenzie explained.

    Perhaps the most concerning revelation from the report was the ever-increasing number of children injured by computers. McKenzie said each year children made up a greater proportion of the already growing numbers of people heading to the emergency room with computer accidents.

    "Young children under 5 had the highest overall injury rate, and they had the greatest injury rate increase over any group," said McKenzie. "There are a lot of young children, really young children, using computers these days."

    Doctors' safety advice for computers matter follows basic home safety rules: keep heavy objects like computers away from edges and on secured, stable furniture, keep cords secured and out of reach, and keep an eye on the child.

    "Computers are not play toys. They are made up of heavy （crushing!）, often moveable （catching!） parts, all of which are strung together with wires and cords （strangulation risk!） and then plugged into an electrical source （electrocution risk!）," Dr. Lara Zibners, author of "If Your Kid Eats This Book, Everything Will Still Be Okay," wrote in an e-mail to abcnews.com.

    放在你跟前的手提電腦、臺(tái)式電腦或者蘋果公司的微機(jī)有多危險(xiǎn)呢？

    第一個(gè)將電腦和急診室聯(lián)系起來(lái)的研究報(bào)告表明，每年越來(lái)越多的美國(guó)人被電腦線絆倒、被掉下來(lái)的顯示器砸到頭和四肢。

    在美國(guó)的一個(gè)雜志《預(yù)防醫(yī)學(xué)》上6月9號(hào)發(fā)表的一篇文章談到，從1994年到2006年，由于電腦而受傷進(jìn)急診室的人數(shù)增加了7倍。

    更糟糕的是，受傷的人數(shù)超過(guò)家庭擁有電腦的數(shù)目。受傷人數(shù)增長(zhǎng)了732%,而電腦占有數(shù)只增加了309%.

    "以上數(shù)據(jù)也許看起來(lái)很多，但是想想在2006年我們一共有150萬(wàn)人進(jìn)了急診室，那么由于電腦而受傷進(jìn)急診室的人數(shù)就只占0.008%."美國(guó)急診室內(nèi)科學(xué)院的博士Charlene Irvin說(shuō)。

    由于這項(xiàng)研究只在100所醫(yī)院中進(jìn)行，如果將所有的醫(yī)院都算進(jìn)來(lái)，也許由于電腦受傷進(jìn)急診室的百分比會(huì)顯著增加。但是 Irvin 對(duì)于電腦這項(xiàng)隱患能進(jìn)前十名十分懷疑。

    相比更加普遍的進(jìn)急診室的原因，比如槍擊和車禍，更能吸引媒體的注意，但是她很高興看到有關(guān)于其它的人們?yōu)槭裁催M(jìn)急診室的原因編碼，形成文件。 Irvin 說(shuō)只有17個(gè)州自動(dòng)提交了編碼。

    這份報(bào)告甚至對(duì)一些在急診室很難收集的數(shù)據(jù)也有很細(xì)節(jié)的描述。比如，由于計(jì)算機(jī)砸到人身上引起的急診室就診事件（21.1%）多于被電腦絆倒或摔到電腦上的事件（18.2%）.男人由于電腦受傷人數(shù)比女人因電腦受傷的人數(shù)多7%.

    數(shù)據(jù)還顯示頭部受傷事件在2003年及以前是增長(zhǎng)的，之后開始下降。作者猜測(cè)由笨重的陰極管顯示器變?yōu)楸〉囊壕э@示屏，更加安全了。

    McKenzie解釋說(shuō)："當(dāng)一個(gè)在急診室就診的病人說(shuō)'我把電腦的顯示器砸到腳上了',那個(gè)人是在說(shuō)'我把陰極管電腦顯示器砸到腳上了',而不是說(shuō)'我把液晶顯示屏砸到腳上了'."

    也許，在這篇報(bào)告中最受關(guān)注的是孩子們由于電腦受傷的人數(shù)不斷增加。McKenzie說(shuō)每年兒童由于電腦受傷的人數(shù)在逐年增加的因電腦受傷的人數(shù)中占了很大比例。

    McKenzie說(shuō)："5歲以下的兒童在受傷率上最高，他們相比其他人群更容易受傷�，F(xiàn)在有很多小孩，十分小的小孩，在使用電腦。"

    關(guān)于電腦事件的醫(yī)生安全建議遵循以下基本的家庭安全規(guī)范：不要將笨重的物品比如電腦放在邊緣處，而是放置在安全的、穩(wěn)定的家具上，電腦線要保證安全，不要放在手邊，時(shí)刻注意孩子們。

    "電腦不是玩具娃娃。它們是由重物組成的（危險(xiǎn)！）,通常是可移動(dòng)的（可拿到）部分，這些部分是由各種線連接的（絆倒危險(xiǎn)！）,這些電線接通電源（觸電危險(xiǎn)�。�."《如果你的小孩吃這本書，那么一切仍將美好》的作者--Lara Zibners博士在一封給 abcnews.com的郵件中寫到。
