摘要 自2019年12月以来,湖北省武汉市相继出现新型冠状病毒(2019 novel coronavirus,2019-nCoV)感染者,病毒持续蔓延,迅速传播至全球,引起了国内外社会的广泛关注。该疾病主要是以肺部病变为主,发展迅速,初期以发热、干咳和乏力为主,少数患者伴有鼻塞、流涕、咽痛和腹泻等症状,继而迅速进展为呼吸窘迫综合症、感染性休克、全身多脏器功能衰竭甚至死亡,致死率极高。由此可见,保证患者呼吸道通畅,维持有效通气是救治重症患者的关键所在。然而在大多数医院中气管插管操作都由麻醉医生完成,长期暴露于高浓度的气溶胶环境中,对麻醉医生的生命安全造成了严重威胁。那么针对麻醉医生进行气管插管时会直接接触患者呼吸道的问题,我们对一次性气管导管进行了改良,即在气管导管末端放置一次性呼吸过滤器,防止痰液喷溅,减少气溶胶的扩散,以期降低麻醉医生在插管过程中被气溶胶感染的风险。 Since December 2019,people with new coronavirus(2019 novel coronavirus,2019-nCoV)have successively appeared in Wuhan City,Hubei Province.The virus has continued to spread and spread rapidly around the world,causing widespread concern in domestic and foreign society.The disease is mainly caused by lung lesions and develops rapidly.The initial stage is mainly fever,dry cough and fatigue.A small number of patients are accompanied by symptoms such as nasal congestion,runny nose,sore throat and diarrhea,and then rapidly develop into respiratory distress syndrome and infection Sexual shock,systemic multiple organ failure or even death,the mortality rate is extremely high.This shows that ensuring the patient’s airway is smooth and maintaining effective ventilation is the key to treating critically ill patients.However,in most hospitals,the endotracheal intubation operation is performed by an anesthesiologist,and long-term exposure to a high-concentration aerosol environment poses a serious threat to the life of the anesthesiologist.Then,for the anesthesiologist when intubating the trachea,it will directly touch the patient’s airway.We have improved the disposable tracheal tube,that is,placing a disposable breathing filter at the end of the tracheal tube to prevent sputum splashing and reduce aerosol Spread to reduce the risk of an anesthesiologist being infected by aerosol during intubation.
