Abstract:
OBJECTIVE: Create an aerosol containment mask (ACM) for common otolaryngologic endoscopic procedures which also provides nanoparticle-level protection to patients.
METHODS: Prospective feasibility study.
METHODS: In-person testing with a novel ACM.
METHODS: The mask was designed in Solidworks and 3-dimensional printed. Measurements were made on 100 consecutive clinic patients who underwent medically necessarily endoscopy, 50 rigid nasal and 50 flexible, by 9 surgeons.
RESULTS: Of the 50 patients who underwent rigid nasal endoscopy with the ACM, 0 of 25 patients with the suction off and 0 of 25 patients with the suction on had evidence of leakage of 0.3 μm particles. Of the 50 patients who underwent flexible endoscopy with the ACM, 0 of 25 patients with the suction off and 0 of 25 patients with the suction on had evidence of leakage of 0.3 μm particles. In terms of comfort, 73% of patients found the ACM somewhat or very comfortable without suction, compared to 86% with the suction on. Surgeons were able to visualize all necessary anatomic areas in 98% of procedures. In 97% of procedures, the masks were able to be placed easily.
CONCLUSIONS: ACM can accommodate rigid nasal and flexible endoscopes and may prevent leakage of patient-generated aerosols, thus avoiding contamination of the room and protecting health care workers from airborne contagions.
METHODS: The level of evidence is 2.
摘要:
目的:为耳鼻喉科普通内镜手术制作气溶胶防护罩(ACM),同时为患者提供纳米颗粒水平的保护。
方法:前瞻性可行性研究。
方法:使用新型ACM进行面对面测试。
方法:面罩是在Solidworks中设计的,并进行了3维打印。对100名接受医学必要内窥镜检查的连续临床患者进行了测量,50个刚性鼻和50个柔性鼻,9名外科医生
结果:在使用ACM进行硬鼻内窥镜检查的50例患者中,25名患者中的0名进行了抽吸,25名患者中的0名进行了抽吸,有迹象表明有0.3μm颗粒的泄漏。在接受ACM柔性内窥镜检查的50例患者中,25名患者中的0名进行了抽吸,25名患者中的0名进行了抽吸,有迹象表明有0.3μm颗粒的泄漏。在舒适度方面,73%的患者发现ACM在没有抽吸的情况下有些或非常舒适,相比之下,在吸气的情况下,这一比例为86%。外科医生能够在98%的手术中可视化所有必要的解剖区域。在97%的程序中,面具很容易放置。
结论:ACM可以容纳刚性鼻内窥镜和柔性内窥镜,并且可以防止患者产生的气溶胶泄漏,从而避免房间受到污染,并保护医护人员免受空气传染。
方法:证据水平为2。
