Question 1

What are the factors that delay the wound healing?

Answer 1

1) infection / prolongs the inflammation & increase the local tissue injury
2) nutrition/ protein deficiency
3) Glucocorticoids/ result in poor wound strength due to diminished fibrosis
4) poor perfusion/ due to arteriosclerosis & diabetes
5) foreign bodies/ fragment of steal and glass
