8. Primary intention
The edges of the wound are closed (in apposition)and
secured with sutures, clips or skin closure strips
usually within 24to 48hours. Simultaneously in 8to
10days, healing takes place throughout the depth, and
little new tissue is formed. For the first 2days, there
could be a little leakage of bloody exudate or of odour
from the wound. A warning sign of a potential
complication is beyond the normal signs that is a
prime consideration in management of risks
associated with the open phase of healing .

9. Secondary intention
The wound has to be left open to allow healing by
contraction and replacement of missing tissue with
granulation and epithelial tissue. This is a common
method of healing in surgical excisions or traumatic
wounds with tissue loss. However, the duration of
healing depends on the amount of tissue that must be
replaced which the resulting scar can be quite
extensive.

10. Tertiary intention healing / delayed
wound closure
Such wound is kept open to allow for drainage of
exudate, control of contamination or for further
surgical procedures to be completed. Usually within 7
days as bacterial contamination rises markedly from
the 8th day onwards, the wound is surgically closed
again. Wound that has to be kept open for longer
periods of time with significant bacterial
contamination has to be reduced before surgically
closed.
