How do you know if you dislodge the graft? 1 week post-op.

In general, it would be difficult to dislodge a graft after one week.  One sign of dislodging a graft may be bleeding.

It is not uncommon for the shafts of the transplanted grafts to shed and fall out in the first few weeks following a transplant. If you truly dislodge a graft seven days into your post op course, there will be excessive bleeding from that site. 

At five days post-op, grafts are not yet fully secured and can potentially be dislodged by pulling or other forms of excessive contact with the area. Normally bleeding will result from a lost graft. If you noticed no bleeding then chances are that you're fine. 

dislodged grafts will bleed and that is how you know that you disturbed them. At one week I would not expect more of these to happen
