JAMA Intern Med:医务人员自我污染率高达46%!

2015-10-15 Mechront 译 MedSci原创

医务人员在移除个人防护设备(PPE)时,皮肤上、衣服上沾染的污染物会导致病原体的传播以及感染风险增加。为探究医务人员移除PPE期间,皮肤和衣服被污染的几率和地点,以及评估对污染频率进行干预的影响,研究者在2014年18月28日—2015年5月31日,进行了一项时点患病率研究和实验设计的干预研究。研究对象使用荧光乳液进行模拟的移除被污染的PPE,以及对另人群进行教育、实践(使用荧光乳液进行移除污染的

医务人员在移除个人防护设备(PPE)时,皮肤上、衣服上沾染的污染物会导致病原体的传播以及感染风险增加。为探究医务人员移除PPE期间,皮肤和衣服被污染的几率和地点,以及评估对污染频率进行干预的影响,研究者在2014年18月28日—2015年5月31日,进行了一项时点患病率研究和实验设计的干预研究。研究对象使用荧光乳液进行模拟的移除被污染的PPE,以及对另人群进行教育、实践(使用荧光乳液进行移除污染的PPE可以随时看到衣服、皮肤上的污染物)等干预研究。

435次手套和医用外衣的模拟移除试验中,有200 (46.0%)次荧光乳液提示皮肤或衣物污染,参与研究的4家医院的污染率差不多(range, 42.5%-50.3%)。同时研究发现移除污染的手套的时候比医用外衣污染率更高 (52.9% vs 37.8%, P = .002) ,因技术失误导致的污染率显然更高 (70.3% vs 30.0%, P < .001)。干预试验结果提示,进行了干预的人群其污染情况显著好转(干预前 vs. 干预后 60.0%  vs 18.9% , P < .001),并且干预1个月以及3个月之后,干预效果依旧存在,这两个时间点的污染率均为12.0%,与干预前相比,干预的效果是很显著的。模拟试验过程中,荧光乳液和MS2噬菌体污染率相似 (58.0% vs 52.0%, P = .45)。

研究结果表明,医务人员在移除手套、医用外衣等防护物时,其自身皮肤和衣服的污染率很高,不过通过加强教育和实践练习(实践中随时能看到自身污染情况)可以有效的减少医务人员的自我污染情况。

抗帕金森震颤手套问世

西班牙科研人员为解决帕金森氏症患者手臂的震颤问题,研制出一种可缓解震颤的智能手套,现已进入临床试验阶段。 据马德里“10月12日大学医院”4月15日发布的新闻公报介绍,这种机器人骨骼手套通过一个行动控制系统、传感器和一组电极来控制震颤。它能分辨出手臂的颤抖是正常的活动还是病灶震颤,从而有效控制震颤。 这家医院已在40岁至80岁的80名帕金森氏症患者中进行了临床试验。戴上这个特殊的手套后,医生和患者
