防护设备可最大程度避免医护人员在医疗环境中的新冠肺炎感染风险

近日研究人员考察了为一线医疗专业人员提供的适当个人防护设备对2019年冠状病毒病的防护效果(covid-19)。
 
研究在中国武汉的四家医院开展,2020年1月24日至4月7日,中山大学附属医院和南方医科大学南方医院共派出420名医护人员(116名医生,304名护士)驰援武汉,为期6-8周。给予医护人员适当的个人防护设备,上述医护人员参与covid-19入院患者的医疗救治。招募77名无covid-19暴露史的医护人员和80名covid-19康复的患者来验证抗体检测的准确性。研究的主要终点为Covid-19相关症状(发热、咳嗽和呼吸困难)和严重急性呼吸综合征冠状病毒2(SARS-CoV-2)感染的证据,定义为鼻咽拭子病毒特异性核酸的阳性试验,或血清样本中IgM或IgG抗体的阳性试验。
 
医护人员的平均年龄为35.8岁,女性为68.1%(286/420),每周平均工作5.4天,每4-6小时轮班,在重症监护室每周平均工作16.2小时。所有420名研究参与者都与covid-19患者有直接接触。在武汉期间,没有一个医护人员报告covid-19相关症状。当这些医护人群回到家中时,SARS-CoV-2特异性核酸和IgM或IgG抗体均呈阴性。
