Question

The risk of implants becoming hematogenously infected
(a) Increases with time after surgery due to enhanced bacterial colonization
(b) Decreases with time after surgery due to host tissue integration with the implant
(c) Increases with implantation of the primary device as opposed to secondary revision surgery (d) Decreases following secondary revision surgeries due to development of immune tolerance by the patient

Justify your answer

Answer 1

Answer- A) increases with time after surgery due to enhanced bacterial colonization.

Reason- 1. Insertion of implants damage or invade epithelial and mucosal tissues therby suppporting the growth of bacteria and serving as reservoir.

2. Invasive medical devices implant impair host defense mechanisms and when contaminated with microbes or bacteria can result in chronic infection

3. Tissue damage caused by surgery increases the susceptibility to infections and bacterial growth.

4. Thus these bacteria spread infection through the hematogenous route causing risks to the body.
