概括
与一次性选择相比,可重复使用的棉花外科帽显著减少碳排放和健康影响. 建议选择可重复使用的盖子,以减少外科手术的环境足迹.
科学领域:
- 环境科学 环境科学
- 医疗保健的可持续性 医疗保健的可持续性
- 外科手术的安全性
背景情况:
- 由于环境和无菌性问题,重复使用和一次性手术盖之间的选择受到争议.
- 目前的建议往往有利于一次性盖子,尽管缺乏证据表明手术部位感染 (SSI) 风险降低.
- 在选择外科服装时,环境影响是关键考虑因素.
研究的目的:
- 为了比较可重复使用的棉帽和一次性布芬帽对环境的影响.
- 评估二氧化碳等效 (CO2e) 排放量,用水量和对健康的影响.

01:10PPE Use in Healthcare Settings II: Doffing
899
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

01:22PPE Use in Healthcare Settings I: Donning
958
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...
