Reactive gel surfaces on operating tables followed by foam surfaces on ward beds vs alternating pressure (active) air surfaces on operating tables and subsequently on ward beds

Proportion of participants developing a new pressure ulcer · preventing pressure ulcers

Reactive gel surfaces on operating tables followed by foam surfaces… may leads to higher proportion of participants developing a new pressure ulcer compared with alternating pressure (active) air surfaces on operating tables and… (low certainty).
