Topic One: Blisters

Blisters occur when the epidermal and dermal layers are separated by heat, and fluid fills the empty space (Vuolo, 2009).

Blisters are not always treated in the same way. Small blisters can be left intact to minimise the risk of infection. However large blisters tend to divide opinion as to whether they should be debrided or aspirated using aseptic technique (Vuolo, 2009). While it is recommended that local guidelines are followed, the general consensus is that blisters greater than 1cm² should be deroofed, while smaller blisters should be left intact.

Blisters on the palm of the hand should be left intact unless they restrict movement. After deroofing, any remaining dead skin should be removed with sterile scissors.
