Self-contamination Following Removal of Two Personal Protective Equipment Suits: a Randomized, Controlled, Crossover Simulation Trial
Anesthesiologists and other professionals are at high risk of viral infection during aerosol-generating procedures.
Knowledge of the protective quality of PPE suits and the risk of self-contamination after removal is paramount.
This trial used an ultraviolet-fluorescent solution to explore differences in self-contamination after removal of gown PPE (PPE-G) and coverall PPE (PPE-C).
A two-period/two-intervention (AB/BA) design was chosen; each intervention consisted of audio-guided placement of PPE, full-body spraying of fluorescent solution, audio-guided removal of PPE, and assessment of self-contamination through ultraviolet light scanning.
The primary outcome was the mean within-participant difference (traces of any size) between PPE suits.
Statistical significance was tested using t test for paired data.

有源比较器：PPE-G (gown) followed by PPE-C (coverall)
Placement of PPE-G (personal protective equipment including a gown for body protection) fluorescent solution full-body spray, removal of PPE-G and assessment of self-contamination through ultraviolet light scanning. Placement of PPE-C (personal protective equipment including a coverall for body protection), fluorescent solution full-body spray, removal of PPE-C and assessment of self-contamination through ultraviolet light scanning. |
Placement of PPE-G under direct instructions (audio recording), fluorescent solution full-body spray, removal of PPE under direct instructions (audio recording) and assessment of self-contamination through ultraviolet light scanning.
Active (wet wipe cleanse of any fluorescent traces visible under ultraviolet light scanning) and passive (15 minute interval) washout period to prevent a carry over effect on the second allocated intervention.
Placement of PPE-C under direct instructions (audio recording), fluorescent solution full-body spray, removal of PPE under direct instructions (audio recording) and assessment of self-contamination through ultraviolet light scanning.
