Outcomes
Primary outcome [1] 288352 0
Record the incidence of skin necrosis following skin sparing mastectomy that requires surgical treatment in all patients within 10 days of surgery. This is assessed by nurses and doctors on the wards who look after the patients postoperatively. There is no specific test as we check the wounds everyday for any signs of wound complications.
Timepoint [1] 288352 0
From surgery up to 10 days post-operatively.
Secondary outcome [1] 299934 0
Measure change in vascularity due to heat preconditiong using laser-doppler imaging.
Timepoint [1] 299934 0
Immediately preoperatively and after heat preconditioning
Secondary outcome [2] 299935 0
Record length of hospital stay
Timepoint [2] 299935 0
