Description of personal protective equipment (PPE)

1.Waterproof gown 2.Mask. The conventional surgical mask does not offer protection if aerosols exist. The type of mask that is required includes the N95 and FFP2/FFP3 masks (which filter 96% and 99% of organisms, respectively). It is preferable to use masks without valves, because masks with valves do not protect patients from our microorganisms. We recommend wearing a surgical mask over an N95 or FFP2/FFP3 mask. 3.Glasses. Because of the power tools, aerosols are produced during procedures, so that complete ocular screen coverage is essential. 4.Full face coverage screen. This does not protect from aerosols, but is necessary when there is a risk of splashing (blood, vomiting, or other biological fluids). 5.Sterile gloves (2 pairs). 6.Cap. It is a good idea for all staff with long hair to have it fully tied up in a low bun and properly restrained. 7.Exclusive footwear for the area of activity, without perforations. We recommend long boots for arthroscopy. Once the PPE is in place, surgical scrubbing with an alcohol gel will be performed on the surgical gloves, and sterile equipment necessary for the surgical intervention (gown and sterile gloves) will be placed on the PPE.
