简述戴无菌手套

答案

参考答案:

尚未戴无菌手套的手,只允许接触手套套口向外翻折的部分,不能碰到手套的外面;已戴一只手套的手,不可接触另一手套的内面和未戴手套的手。无菌手套有干、湿两种,以干手套最为常用。

1.戴干手套法先穿无菌手术衣,用手套袋内无菌滑石粉包轻轻敷擦双手,使之光滑。用左手白手套袋内捏住两只手套的翻折部提出手套,使两只手套拇指相对向。先用右手插入右手手套内,再将戴好手套的右手2~5指插入左手套的翻折部内,让左手插入左手套中,然后将手套翻折部翻回套压住手术衣袖口。用无菌盐水冲净手套外面的滑石粉。在手术开始前,应将双手举于胸前,切勿任意下垂或高举。

2.戴湿手套法在灭菌手套内先盛放适量的无菌清水,使手套撑开,手易于伸入。选取适合自己手大小的手套,解开灌有清水手套套口的绳结。以左手拇指、食指及中指提住撑开套口,迅速将右手伸入右手套内,使各指尖直达手套指部之顶端,然后将右手腕向上背伸,使手套中积水向腕下方流出。再用右手指插入左手套的翻折部,并提起,将左手同上法插入手套中,使水依右手方法从腕下部排出。戴好湿手套后,再穿无菌手术衣。

手术人员做完一台手术,需继续做另一台手术时,可按下列步骤更换手套和手术衣:①洗净手套上的血渍、污物,先脱手术衣,后脱手套,注意双手皮肤不得接触手套外部及其他物品,以免受污染;②在流动清水下冲洗双手,用无菌毛巾拭干;③在70%酒精或0.1%新洁尔灭等消毒溶液中浸泡双手、前臂5分钟,待干;④再按上述方法重新穿无菌手术衣及戴手套;⑤若刚完成的是感染手术或手套有破损,则须按常规重新洗手进行手臂消毒。

小题1: In this collection, Bill Bryson is writing from home. We find he assesses life both in New England and in the contemporary United States. With the telescopic perspective(远望视角) of one who has stepped out of the American mainstream and come back after 20 years, Bryson holds the mirror up to U.S. culture and feel strange to his motherland.
小题2:This book is a guide to the world’s unspoilt sights and experiences. It presents one thousand fresh and fascinating alternatives to hundreds of well-known tourist destinations and sights, including alternatives to the Carnival in Rio and the beaches of Thailand, the most-visited national parks, over-rated restaurants and holiday sites.
小题3:Returning to the U.S. after 20 years in England, Bill Bryson decided to reconnect with his mother country by hiking the length of the 2100-mile Appalachian Trail. Awed by merely the camping section of his local sporting goods store, he still goes into the wilderness and learns hard lessons about self-reliance.
小题4: A travelogue by Bill Bryson is as close to a sure thing as funny books get. This book is no exception. Following an urge to rediscover his youth, the author leaves his native Des Moines, Iowa, in a journey that takes him to across 38 states in the country, which is like a small town in his opinion.
小题5:Born in Iowa, Bryson backpacked through Europe as a young man. While living in England some 20 years later, he revisited many of the same places from arctic Norway’s northern lights to romantic Capri in Italy. Here he jumps back and forth between old memories and new experiences.
