Why not 21 days? What's wrong with 7 days? why not a month?
Where did your immunologist found the magic figure of 14 days?
In terms of clean surgery - an immunosuppressed patient is not different
from any patient; the contamination-if any-occurs DURING the operation;
after the operation the wound is rapidly-within few hours- sealed. So
NOTHING, NOTHING can change the fate of the wound AFTER the operation which
is determined DURING the operation . This is true for any type of patient.
Your patient needs a good antiseptic bath to decrease her skin flora,
PERI-OPERATIVE antibiotics, careful hemostasis, avoidance of
bacteria-loving suture material (i.e. silk) and nothing else.
Ask your immunologist to provide you with references to justify the 14
days. Tell him he talks nonsense!
